Suggested turbo size for a TT 5.0 305 camaro...
 

Okay what should I start with for a turbo size...i figure the 14b would be wayyyyyyyy to figgen small...like a rhb5 on a h22a right? I want to do something junkyard/flat rate style so what would be a decent turbo to start with/

btw, this is going on a 305 small block camaro 5.0...

thanks

just make the flanges for a T3, lots of options to go wither there, make this thing 350+ capable.

Post pics of your progress fool!

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

do you have a mullett?

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

if i may ask, why are you going with the week 305?

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

LOL.. I made a post like this some time ago. I wanted to TT an 83 Camaro Z28.. hopefully yours is newer.. The reason for turboing a 305? Its whats in the engine bay, most likely.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

are your eyes chinky?

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

hehe 305s are such garbage but if its in there and you cant swap nothin because of $ might as well turbo it.

it'll give it a kick in the pants at least

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

nothing wrong with a 305 when you can't afford anything else. I ran with a 305 for a few months - I hated it but I lived.

Boost the ---- out of that thing and make your setup 350 do-able.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

Okay, First off, I ------- HATE mulletts.

I live outside this small ass town of 2500 people that is all farmers and hicks. I hate the bitches. I have a CRX w/ a JDM dohc zc. Those bitches at my school are all like "stroke it, over bore it..put posi in that little thing" there are trucks at my school that would seriously have no problem driving over my car.

anyawys, so my other buddy has a camaro. he is currently lookin for a 400 small block to build up for it...and yeah it has the bad ass 305 in it. I cracked the joke that we should put a pair of turbos on the 305 becuase he is all interested in how im putting a turbo on my crx. so he is like, okay i'll put a grand towards it if you want to build it.

the fact is that in this area, 305s are ------ worthless. shops will set them by the trash hopeing poeple will take them awayt so they dont have to pay the $10 to have the junkyard take them.

that car has the tuned port injector or whatever the ---- right so it is fuel injection so turbos will work great wtih them.

all of the hicks in this area will be like, what the ---- are those.

and it doesn't matter if we blow the ---- out of this motor...it is going to be pulled anyays...might as well blow the heads off so we dont' have to take them off.



so what would be a good turbo size to start with?

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

;D Dont mind these guys they got 4cyl on the brains.Lets take a look at the 305 low compression + for turbo Has same crank as a 350 another + The rods are the same as a 350 another + cyl heads interchange with a 350 Another +.
Head gasket is a solid metal gasket that crushes to .015 thickness another +
Has the tune port injection system another + but not really neeed.
The 305 engine a negative in everyones eyes.But the + to it is readily availible.Like a d15 dime a dozen....

If i could have gotten those forged pistons for 115.00 bucks i would have boost a 305 instead of 283. 20 to 25 psi boost before something would let go.Would run like a rapped ape in the mean time.
Anyway if you gonna twin turbo it i would start get a pair of chrysler lebaron turbos or pair of mitsu turbos which i beleive they are a lil smaller quick spool.If you got any other questions email ill help you out i got knowledge in the turbo domestic area.
Go for it boost it till she blows all other sbc will bolt in when she does an you got a wide range of motors to swap in when she goes....

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

okay Nathan I have a feel from where you are coming from.

I wouldn't suggest getting a 400, they are sometimes a bitch to come by and need "special parts". What I mean by that is that if you need new heads then you can only use 400 heads (which are pretty shitty). Most people use 350 heads and have them machined with that extra water port found on the 400 sbc. I would say stoke a 350 motor. A 383 can put down some serious power.

Your biggest challange will be fuel managment, have you decided what you wanted to do with that yet?

Here is a good website to show you what to do to build the ---- up:
http://www.2quicknovas.com/doesgo2003.html

If this guy has some money to throw around then go for standalone fuel managment but carb setup will work.

Let me know your progress, I'm going to start one of these TT v8 setups soon as well (a few guys around here want to).

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

I was just planning on a FMU unit or something like that....

dont feel like spending a hsit load on a stand alone and im pretty sure i couldn't chip it with turboedit or anything

yeah the 400 was made in the "smog era" or someshit right? so it's ports are mad small...but yeah

there is one guy that has a 400 otherwise he'd prolly go wtih a 350...

it all dependson what we find

what options do i really have as far as mangment?

would the AFC hack work on this....if it would it'd be tight as ----



one more thing, so like a pair for 14b turbos should be pretty good size? they run like 2.2L so yeah...we'd like the turbos to spools low becuase the redline is like 5500 on this motor


nathan

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

Yes there is port differences between all differnt casting number heads but all sbc heads from 267,283,302,307,350,400
are interchangable.The 400 has 2 steam holes in them so all you do is take a 400 head gasket center punch the 2 holes between the cyl an drillem out.I checked out the page on the twin turbo setup an thats alot of work on welding.I got a set of block huggers an turn em upside down an built exhaust from there into a single t3 spools quickly 2200 an pulls all the way to 5k or so to busy driving to just look at tach.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

I've never fucked with any 400s so I don't know the specifics but I did know about the ports in the head.

I'm with Ted on this one, T3 would be more ideal. Try and find a couple off those older chrysler K cars. Those cars are 2.2 and 2.5 litres and should be able to flow on a 5.0.

---- your stock fuel delivery system man, go standalone. With man standalone setups they are live feed to the laptop and can do more then uberdata (no chip burning needed either).

I'm drooling over some ultra megasquirt, look into that ----, build yourself a $1000 setup for a couple hundred bucks.. I can't wait till it gets released!

-ry

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

;D why go fuel injection theres guys doing 25psi through a carb. What i have learned on my setup i pretty much got the carb mods down to a tee. My fuel on a wide band is comparable to a fi setup.Check out this 7 sec carburated blowthrough turbo video.
www.tysonracing.com/786.MOV

just thought i would add this to this thread.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

do those ports look small?

https://www.homemadeturbo.com/jbliss/sb409_2.jpg

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

well no, Those heads look exactly like the ones i had on my camaro.They where world product heads. :D
Hm that even looks like a rpm preformer manifold.I like the holley strip dominator myself straighter ports an more air under the runners for better heat transfer....Also i see those heads are the dual valve cover set up center bolt an outer bolt.... ::)

Nice engine you got there.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

heh you are good i must admit!

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

Im the small block guru of hmt. I got just about any sbc engine you want or need in my garage.My plan was to turbo a 400 sbc but the block need to be decked due to some minor rusting around a head bolt hole an this made pits under the headgasket fire ring.An with the pistons i had it would have given me to much compression to turbo.So i goona just throw my 350 with some forged slugs in for now till i get the 500 caddy engine ready for the twin turbo swap.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

its a holly street dominator manifold :P

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

Damn spark plug wires in the way.Couldnt really see the front very well...

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

yeah cadracer is the man.. I can hold my own with the chevys but he's definately got us all beat.

oh and the reason why Bruce with the nova didn't just do it the quick and dirty way like you is cause he really doesn't have the room like we do under the hood of our trucks. Man I jump in the motor all the time when I gotta do ---- to the truck, stand on the steering column or frame rail and away I go.

It's good to know that you've fine tuned your carb like that, I'm still in the air as to what I want to do. Fuel injection would be great for efficiency but carb would be simple. I would have to go out and buy a holley double pumper since the only functioning carb I have right now is an edelbrock (1400 series i think) that is on the truck. I'm most likely going to have to go go with fuel injection on the truck since I get into some really hairy manuvering with it (living in the mountains baby) and the carb likes to flood out at angles. Yes I know I could always install a solid float and it will take care of most of the problem... I'll worry about it later.

I just want to go fuel injection on my sleeper cause it's just cool to have a laptop sitting next to you while driving ;)

If anyone wants to go with standalone let me know and I will see how far I can help you, I've been reading up on the ---- for a while and it's the route I'm gonna go (megasquirt yo).

-ryan

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

:D well damn your in luck i so happen to have a complete tpi setup minus ecu an harness.If your interested in it let me know i was gonna use it but i modified my carb to do work at this time. 8)I have been looking into the megasquirt stand alone on the tpi unit but just havent needed it at this point.But my truck is 2 wheel drive an you can barely slide a floor jack under it to raise it.Its pretty low an i like it that way for now...Im running 15 psi on stock internals just put in new cast alum pistons an a high volume/pressure oil pump.With a mild solid roller cam an the 283 puts out almost 400ftlbs torque at 3k 4x4 would love that.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

i was thinking of just going standalone all by itself.. as in a build up for the volvo v8 project. On the truck I'm not sure yet.. was thinking about just buying the solid float from edelbrock and seeing how she handles after that.. maybe a little bit of wide band tuning for that carb ;)

It's going to be like 4-7 months before I get back to her, I have the integra to play with right now while I'm living in florida for a bit.

I'm waiting for ultra megasquirt to get released, that ---- looks soooo hot man. Utilizing full time wideband o2 sensors, map sensor and spark control. Man I read all of their website and it has so much potential. You can daisy chain like 5 units together to get more functions out of your car, sequential fuel injection.. I can't wait to build one.

the setup would look something like this:
http://www.sdsefi.com/sbman.jpg

custom made fuel rails, modded intake manifold (gotta tig them injector bosses in). it should still sit lower then any carb after it's done.

What do you think Ted?

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

Damn Thats looks awesome.I was thinking obout that type of setup on my caddy motor cuz just on motor alone it has stock 825cfm carb. My desktop dyno shows 1100cfm needed for the 520 cube caddy motor an now add a turbo setup an now i would be looking at probably a 1150 dominator for adequate fuel if i was carb.So fI is probably in future if i want to get good power.
::) hm twin turbo, twin carb twin bonnets each feeding from each turbo. Would look way wicked....Just an idea.
See what happens in my head to many ideas an not enough money to try em out.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

man ultramegasquirt would work well for you.. I bet you'll be running dual injectors and ---- with that many cubes.. I was thinking a dual 600 carb setup right when you started talking about it.. that setup sounds pretty insane.

I'm going to have to scour the megasquirt website again (and join their forum) and try and find out what's up with the ultra megasquirt - it is still in the testing phase.

Man you can do more with it then you could with say your basic thousand dollar standalone setup, it just looks unreal. You get live feed to the laptop, no roms to mess with, change your timing curve and know your EGT on the fly man.. simply awsome. I bet you'll have to set a few of the modults in series to control the 16 fuel injectors that you'll most likely need :o

I'm gonna have to give you a final price and ----.. count on things like wideband o2 sensors, map sensor, various coolant sensors and simple GM sensors for whatever operation. I was thinking around a couple hundred bucks to build the main control box, including pc interface and ----, add on all the sensors and misc stuff you will need and give you a general price.. hell of a lot cheaper then running two new carbs and high rise intake manifold.

I'll look into it all tonight and get back to you, I think the guys are hounding me to go make some food right now.. lasagna sound good tonight? Oh yeah Ted, if you need me to assemble the board for you I can solder it all together, I'm just itching to make it myself.. gotta still make a few DIY wideband o2 sensors too.. damn I need to go meet up with an electrical engineer for some circuit designs.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

think we jacked the hell out of this thread enough? If I create a megasquirt ultra thread later I might seperate a few of our posts over to it.. but at least we are giving plenty of usefull info to the TT 305 guy.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

;D Hell ya i think we jacked his thread lol. I think we covered the info for him though.I got 3 305 in the garage think i gonna throw one in the 77 camaro an see what it will do with a t04 single setup.Ill just rob most parts from the truck since im changing to the caddy motor.Im down for the help on the mega squirt.They way i would do it would be fi an then add a nitrous spray bar under the billet throttle body an ad fuel that way when boost is applied.2 fuel solenoids one on with 5psi other on at 13 or 15 psi.think that would handle it.Yeah let me know cuz i know jeff hates me changing directions on these projects.Too much down time for him but he can just concentrate on himself family guys have a few more things going on so our projects take longer......If you make a megasquirt topic ill be there

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

Did you see this?Gives me goosebumps

www.tysonracing.com/786.MOV

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

yeah that's just scary, I'm not even near those kinda goals.. like 700HP would subdue me just fine. Eventually I would love to do a BBC buildup, quad turbo or some ----.. 454-502 buildup would be fun.

_____________________

I'm waiting for them to finalize ultra mega squirt man, it's going to be on! They have spent thousands of dollars in R&D for this thing, they are making it bosch wideband compatible so we don't have to pay the jacked prices for the honda vx sensors ($60 each versus $300 - both new). Man it would be so sweet to have dual wideband that's full time on your car, or you could swap out for narrowband if say you wanted to run race gas?

Tonight I'll have to dig up all the ---- I already found the other day and see what I can provide you. It's going to be a few months before I'm even around any of my v8 cars but I can help you with design or layout on whatever. The new setup is going to be so nice, 100mhz processor controlling every single electric function of the motor.. man I can't wait! This is more advanced then many of the "pay a grand for our ----" setups.. you can even go DIS and run coil packs ;D.

Like I said, I'll find as much info for you and we can be ready to build one of these things when the ---- gets finalized (they are still ironing out some bugs and trying to get the precision wideband ready). If you want me to solder the ---- together (since this is hardcore DIY) then I got you on it man.. damn I wish I could be there for the install, maybe one day. For now I have to work on some circuit designs for a HMT wideband kit that is costing me next to nothing to run wideband ;)

Ill Be the ginney pig. I like r&d it equals a price break an future upgrades that need to be worked out...

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

megasquirt is all non profit man, these guys just develop and design this modern ---- for fun.. when I start running it I will gladly join their test crew and offer whatever support I can, it's been a long time since I've even picked up an osciliscope but I can definately assemble a DIY project. Got a laptop man? I think this new ---- is going to offer full data logging capability. I would expect to spend tops $500 for everything to switch from carb to fuel injection.. possibly as low as $300.. I'll find out later and get back with you ;)

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

so how exactly could i set this up wtihout a standalone?

i'd like to be cheap as possible

nathan

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

Check out Ted's setup where he did the SBC turbo project.. he did it very cheap and effected, holley double pumper. I'll clean this thread up later for you man.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

hmm need a laptop i got like 10 of them here on my computer desk.I build em.I get the raw parts from ebay an assemble them for peeps for what ever there need are so i got that area covered.I got all the injectors an sensors an dist all i need is wide band o2 an wiring an billet throttle body with iac.I have seen the megasquirt boards for 125.00 an then you add the injector relays an so forth to customize it for your application.Just sold the gtr 32 turbos i had to a guy in germany so i got some money in my paypal which is gonna be alocated to the caddy turbo project.I wanna try out that huge turbo i had an see how well it responds to the caddy engine.If not i will do the twin ct26 supra turbos i have sitting here to be used.If you know anyone who needs a laptop for pcm programing or anything else let me know.My nodels are the gateway p2 an p3 solos. 13in screens all the way up to 15 with p3 700mhz.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

I got a laptop, well it's always down for repairs.. I'll have it working eventually. You need to wait out on the ultra megasquirt that utilizes wide/narrow band and also controls everything else. I would wait out for that one, supposed to be 3 times better then the current megasquirt II and worlds of advance upon the first one. I would hold off myself but you could always do the first setup (which is fairly cheap) then upgrade when you get the technology ready. I don't know of the current megasquirt supports dual o2 sensors either.. I don't think it does.

Your call man, I'll provide what info I can after I spend a few hours reading their website again.. maybe tag the forums up a little bit.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

What exacatly are you putting this in since we jacked your thread.I would be glad to help out.Where do u live?

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

yeah I'll clean your thread up once I get motivated.. I just feel like going to bed instead tho.. i'll clean it eventually.

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

you two need to get a room ;D

Re:Suggested turbo size for a TT 5.0 305 camaro...
 

don't worry, we'll have our own thread instead.. much better then a room.
