i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

i'm not too clear on what exactly i need and need to do with TT'ing my CARBed 350 V8.

heres what i think i need and need to do:
-get a boost carb
-get a carb encloser(or make one. since there ALOT of $$$)
-make manifolds
-get 2 turbo's
-oil lines
-piping and couplings
-FMIC

the things i'm getting hung up on are:

-what kind of turbo's should i use?

-how am i going to actuate the wastegates? (i'm thinking of making 'em mechanical. i.e having cables attached to 'em, then to my throttle. so when i step on my gas pedal. i'll be using the wastegates!?!)

-how would i control the boost levels? (would the above ^ thinking take care of that?)


thats all i can think of right now sinces it's about 6am. i'm sure i left out things.

thanks

there is an article in the Turbo Project section that a guy turbo'd his 5.0 mustang. I think he used 2 m10 turbos

Wastegates have a spring in them and let extra gas out when the turbos make enuff pressure to force the spring open. Get a 5 psi wg.

Ur mechanical idea is the most ghetto thing i have ever heard of. Get a manual boost controller or get the Turbo XS dual stage boost controller for around 200 new

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

wastegates allready are mechanical. They have a spring and a diaphram. lets say you have a 9 pound spring in the waste gate. then it takes 9 pounds of boost to push down the waste gate then it opens to allot pre turbo exaust gas to come out so your turbo is regulated to 9 pounds of boost..... your planing on running boost into a carb? you have to do a draw through method. just like superchargers do. the carb goes pre air compressor and you make a box that goes on the intake plenum so you can hook your charge pipe up to it.

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

yeah the 5.0 TT project is for a fuel injection setup. what i mean "what kind of turbo's should i use" is: the're diffirent kind of internals. i.e ball bearings, some are oil and water cooled, etc...

i have no vacuum on my S-10 besides the brake booster. to my understanding wastegates need vacuum. right? so i can't hook that part up!! how would i be able to bypass that part of the wastegate?

yes i'm planning on boosting into a carb. but since my V8 isn't fuel injected. i need to buy or make a "complete" carb encloser. meaning that the carb is fully enclosed and all that is out of the encloser is the fuel lines and throttle cable. but i will also need a "boost carb" that is designed for turbo.

thanks

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

how could you have no vacuum... lol

get some T3 turbos with internal wastegates, you hook up a vacuum line to the wastegate acuators, pressure makes them open.

the carb incloser is stupid, modified your carb or buy one that is modified to accept boost. and you put a bonnet on it. you dont enclose the entire thing

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

so where do you guys get vacuum when your intake is pressurized due to the turbo forcing the air into it?

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

The wastegates need to see vacum and pressure from the manifold or charge piping.I have been helping a friend of mine with his turbo Nova project.He is using a MSD boost timing master to pull timing under boost and will be getting a turbo ready Holley from the carb shop I believe they are called.You can do twins or just run a large single like my friend will be as you then just have one downpipe and charge pipe to build.A good resource for turbo small blocks is http://www.turbomustangs.com/smf/ they have a section on sbc as well.

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

the wastegates dont run on vacuum, when they see boost pressure is when they move.

when you're not in boost you will still have vacuum

ok i'm following you now!!

90dx thanks for the link.

pics of the turck

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

the only 2 pics i have of my S-10 are of the front and when we pulled the old tired 350 out of her.

here are links to 'em:

(in this pics you can see the tail end of my boss's '74 corvette. we just dropped in a ZZ383 crate engine from GM in her. and i got his old 350 in my S-10 now ;D.)

my S-10 is underconstruction. i'm doing all the performance and lowering before i send her to the body shop to get painted. i hope everything will be done in about 3 months time.

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

i know i know the question i'm about to ask is STUPID. BUT i have to ask it :-[ :

how does a manual boost controller work?



also, i have 3 turbo's: 1 is from a merkur T3 .60, IHI RBh5, and a diesel turbo off of a GM 6.7L.

would it be alright if i use my 2 small turbo's(T3 .60/IHI RBh5) together for my set-up?
or should i go with the BIG BOY diesel turbo?
and why?

thanks

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

I dont know the specs on that diesel turbo but sicksix on this site can probably tell you how it performs.Those two you have should work good for a twin setup though.What are you planning on doing for manifolds?A manual boost controller goes in between your vacum single for the wastegate/s and bleeds off some of the signal so the wastegate thinks it is at less boost than it is.They can be used to increase boost but not to lower past what the wastegate is set too.

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

it would be really benefitial to yourself if you researched how alot of these turbo parts work and what their function is (wastegate, bov, etc...) Once you have a firm understanding of how all these things work, it will help you to better decide how to build your setup, and what you do and dont need, and how to use each item you have properly... then things will go really smoothly for you

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

i plan on making my own manifolds.

Check this one out.......lots of good info

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

thanks for the link turbo_camaro.

i have another question:

-i'm trying to figure out the oil part of the build. and a friend of mine doesn't see how the oil gets back to the engine. anbd i tried to explain it to him. but them i got confused as well :S.

so how does the oil get back to the engine and not starve the engine of oil?

thanks

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

I just made a ½ inch return line from the turbo to the oilpan.
Just make sure you put it where there are no rotating parts at the place you put your return.
Otherwise oil could be splashed back into the return line.
Best to put it where you have a main cap.
And always put it above oil-level....... or as i do: as high as possible in the oilpan.
Make sure it doesn't have any kinks or sharp bends in it.
The oil doesn't like that........
For oil supply..... I just took out the original sender at the back of the block.
T'ed it from there. Oil pressure sender can than be put in the side of the block.
Just above the oilfilter......

Hope this helps....

I guess people dont know how to use the search feature on this site of vast information.
For starters check out the turboed sbc an i beleive there is a link to hangar18 for the carb modification.All i can say if you dont understand the workings of a wasgate then how are you gonna tune this sbc when you boost it. ::)

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

i did search the site before i posted. i just didn't type in "truboed sbc". if i had YES i would of found some info!!

i have hanger18's site saved.

i do understand now how the wastegate works.

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

:o some info? I beleive there is enough info for you to do the whole project.If you want a carb an bonnet i got one i would sell you.Holley 650 dp all mods done with bonnet dial in for daily driven 7 psi boost. If you have a good fuel pump you could crank it up to probly 10 without any problems.....Let me know
