hello,
 

hey, im new to the forums,

ive just got a few questions

first of all im from australia and im driving a 3.8L v6 (vn commodore)

its a buick LS3 motor (89)

whats stopping me from throwing a smallish turbo such as a t3 onto my motor,
what exactly would i need to achieve a stable 6psi setup???

cheers

kick yourself in the testicles

Re: hello,
 

sheesus nice to see someones help ful :o

Re: hello,
 

yeah most people here pretend to be helpful and all they do is bullshit around and make fun of people. In order to avoid this, the best thing you can do is READ. Search the forum. Look into the turbo projects section. Get some ideas about how you want to rig things up. Then search for more info on those ideas. Look into manifold setup, fuel delivery, engine control, IC mounting points, turbo sizes and applications.

There is a myriad of information at your fingertips on this forum. Most of it will NOT come from replies to your post. Believe it or not, someone has probably asked your questions already .... atleast 3 times. No disrespect, but doing your homework should help you to avoid "helpful comment" and also let you in on the knowledge your after.

Re: hello,
 

You'll get help when you ask specific questions (which would indicate thought and possibly reading/research on your part).

If you say "Tell me what I need to do to boost my car" then you're going to get shitty replies.

That's just how it is... :8

Re: hello,
 

lol aight, i wasnt just asking a question without searching up on it,
im still learning about how a boost setup works.. someone correct me if im wrong,

to run a stable 6psi setup, can i get away with using
turbo
manifold
piping
blow off valve
oil line
boost gauge
hose clamping and stuff
some kind of modification to the memcal (ecu)

so my real question is, could i get away with running that boost with that setup, is there anything else i require and is a ecu modification actually required?

cheers

Re: hello,
 

Downpipe
Exhaust

As far as engine managment, i'm thinking the easy would be to run an fmu :3
As far as chipping, :S

Re: hello,
 

cheers man,

with the exhust are you talking about custom headers?

my exhust system is a 2.5"

whats involved in fitting the downpipe?
say an extension pipe inbetween my headers and my cat converter?

as for FMU ill look into it, the reason i say remapping the ecu is because i have all the materials to do it, (eprom reprogrammer, memcal, and all the required tools/roms required)

once again thanks for all the help

Re: hello,
 

ok you can definatly run a trubo with that setup but it will take some serious piping to connect both exaust manis to the turbo. I would also recomend a delete cat pipe and a lager fuel pump along with your fmu, maybe a walbro 255lph. this is definatly a dooable setup its just going to take a lot of research on your end.

cheers mate

Re: hello,
 

Maximum Boost by Corky Bell. It works wonders for those who are uneducated about the ways of boost.

Re: hello,
 

Corky Bell is the turbo GOD...look him up

and correct me if im wrong but isnt a T3 a little small for a 3.8 litre engine??

Re: hello,
 

The bigger T3s were on 2.3L 4 cyl in OEM applications. You want something larger-or two small T3s

Re: hello,
 

Quick somebody hide that ---- about corky bell.
JD is gonna be pissed :P

Re: hello,
 

for all of you who dont know the motor ill lay it out for you

3800
v90 config
single camshaft
redlines @ 5500rpm

125kw @ flywheel
around 90rwkw~
292nm torque

with a bit of tuning its already around
100rwkw
300nm torque

as for a t3 being a little small, im really not after a crazy boost setting just something along the lines of 6psi-9psi
i investigated supercharging but that would cost alot more, the reason i want 6psi-9psi is so that i dont have to use a intercooler/modified head

my cousin just threw a larger turbo on his R33 skyline (gts)
does anyone know what that turbo is? im pretty sure it was running @ 9psi on a 2.5L straight 6 engine

i'll definatly read up on it, hoping to do this setup for as cheaply as possible, thanks for all the help

Re: hello,
 

i think its a t25 or t28? You could boost with 2xt25s or ihi rhb5s and that car will rip. For a single turbo setup get a T3 48/60 or a 60/63

Re: hello,
 

how much roughly are the T25's? im looking for a budget setup, and the piping for 2xT25's / the turbo cost themself might be a bit much just to run anywhere from 6-9psi boost

could i get away with 9 with no intercooler?, i know that most turbo cars come running with 9psi, but im geussing they roll out of the factory setup for 9psi, where mine rolled out normally aspirated, ill look into it, thanks for the suggestions, it all helps

the T3 AR.60 looks like a good choice, not too bad pricing either, am i correct in saying its the turbo used in supra's? i think the 96 model

Re: hello,
 

An intertcooler has nothing to do with how much boost you can run, it has to do with wether you are gonna blow up your engine or not

Re: hello,
 

You should consider an intercooler. Read all the stickies on this site, LOTS of information is available at your fingertips. Post, and you will get flamed, and ultimately feel worthless. Read, and you will learn much! :y

Re: hello,
 

Post pics of your car!

Re: hello,
 

lol, Corky Bell is a douchebag and is book is helpful if this was the 1970's. :-\

Re: hello,
 

But its still a good start to to get you caught up on the whole turbo idea if ur not very informed

Re: hello,
 

Yeah and so is this: http://www.turbobygarrett.com/turbob...ch_center.html :-\


The bottom line is Maximum boost is an outdated waste of money and anything in that book can be found online for free.

Re: hello,
 

Oh yeah, it's so outdated ::)

It actually has a lot of good information in it. I guess turbocharging has changed a bunch since 1997 ::)

Re: hello,
 

Don't roll yours eyes at me fag. Its a great book that shows how to install an FMU. ::) And no absolutely nothing has changed since 1997. Just look at your average turbo Honda, the setups today look and perform exactly the same as they did in 1997. :-\

Re: hello,
 

It's a book about designing turbocharger systems, not necessarily tuning them. Obviously there have been huge breakthroughs in engine managment and the availability of parts, but the actual theory, design and fabrication has been the same since who knows when.

1997 is a bit more current than 1970, fag ::)

Chill the ---- out, what crawled into your vagina?

Re: hello,
 

see the bottom of this page for a picture of the engine bay (note pod filter now using proper clamps/piping and housed in a heatshield)

the engine bay is bigger just looks smallish due to the angle of the picture
