can you tell me exactly what turbo you used because I obviously need something better than the T25... I wouldn't mind using the TGP x over, flange, and downpipe either so I am interested to see what turbo you used that just bolted on.

Dave

thanks again for the wisdom... I looked around and it turns out I will most likely be going with something in the T3 family.  We can fabricate a flange pretty easily... I mean, just take the X-over you have now and the turbo to a machine shop and they set you straight for about $100-$150.  As for the downpipe, I'm sure they could do the same thing for us... that's what we did with the TGP turbo and the cavalier... the downpipe didn't fit so we cut the part we needed and they fabbed the rest for like $50.  

Find a good exhaust and machine shop and you won't have a clearance issue in the world!!  Anywho, thanks again for the 2 cents... i still think we'll be gettin some 36# injectors though just to keep my options open.  Oh yeah, we're burning a chip and Marcel hasn't done one for a 3 speed auto before... anyone have any advice on this one?? :(  

THANKS AGAIN... AND AGAIN! :)

Dave

well seeing as how the entire world recommends a better turbo... any recommendations?  I noticed you listed 2 in your post but keep in mind that I don't know what those mean... I'M NEW TO THE TURBO/TGP WORLD! :)  thanks SOOOOOOO much for all your help guys!  You have no idea how long it would have taken me to figure this crapp out on my own on the v6z24 boards.  

So for now... I need to get some 36 lb injectors, and MSD box, a chip tuning, and a better turbo... sigh... better hit the lotto soon ;)

Dave

man where were you guys 3 years ago when I started this thing! :( coulda spent the money MUCH better!

haha, thanks man... 'save as' indeed  :lol:

www.jcob2.com
click the project zoturbo link on the left.  that'll give you an idea of what we are dealing with.  I REAALLLY wish I woulda known about this site when we started this project :( lotta goodies here that i didn't know b4.

So provided I get some 36lb injectors AND a chip tuning is there any reason I can't crank the boost a little higher?... say 18-20?

Dave

so seeing as how this boost is 'less powerful' are you saying I can safely crank it higher simply b/c it's a T25??

Dave

Hey guys, I too am a recent graduate of V6Z24... still love the site!  Anywho, i posted a thread in the performance section and we have come to the conclusion that simply having my chip burned is the way to go.  

i was wondering A) what hardware/software I would actually need to burn a chip and are the chips a 1 time burn or can you re burn the same chip a million times?  and B)... could someone make me a chip instead  :oops:  :oops:  :oops:  

I have a modded 3.1L TGP motor and we currently have the stock TGP injectors a 3 speed tranny w/ a shift kit, all kinds of engine mods (heads/plenums/cam/etc.) but we will be running around 14psi so TIMING IS THE ISSUE! :(  We need to remove the speed limiter and change the timing curve basically... thinking 1.5-2 degrees of retard /lb of boost?  Sound about right???

ANYONE!?????? :cry:

Hey guys, thanks for the info thus far!!

To answer some of your questions...
it is a 3 speed automatic with a shift kit
this was a 3.1 turbo from a TGP that we basically tore apart and built up.

And yes, after doing A LOT of research, i'm going to have to agree that I should get rid of the FMU and MSD box and have chip burned.  

And the reason we are keeping the small turbo is mainly because of the cost/power ratio so to speak.  Since we can't run over 14psi b/c of the weak heads/gaskets/tranny and other weak points we decided to keep the t25.  Like i said before... the v6z24 board didn't have too many TGP experts and in retrospect the forged bottom end might have been overkill :(:(:( but I was told that anything over 8psi would have popped a stock piston or 2.  

Oh yeah, and any ideas how much timing I should be pulling when I burn a chip?  I'm assuming 1.5-2 degrees/pound of boost?  Sound about right?? Anything more specific would help though ;)  

THANKS GUYS!... I feel right at home :)

oh yeah, and who are the chip burning people I should contact?

Hey guys... I too am a graduate of V6Z24.com :)... still an awesome site though!

Anyway, I have a pretty heavily modded 3.2T (was 3.1L)  but have some concerns and questions that i haven't really had answered by the J-body folk.

Here is my setup
3.2L Turbo (stock t-25 garrett)
255 lph in tank fuel pump
Stock Cavalier ECM and memcal

now we are tuning and we obviously have some timing/fuel issues.  We plan on using an MSD DIS-4 box to pull timing, and use an adjustable procharger FMU to compensate for fuel.  

I've been told that the stock TGP fuel injectors are no good after about 10 psi.  Is this true??  Do I need to upgrade?  Also, I was told that even though I've got a strong fuel pump, I should still throw in an inline pump or my in tank one will die on me sooner than expected.  Are these both true??

I have a forged bottom end and provided eveything is tuned we're expecting 330ish crank HP.  That's a biig if though seeing as how we can't seem to figure out our tuning issues.

So....
#1) Do I need to upgrade my injectors and what do you guys suggest.  Also where to buy em would be good ;)
#2) Do I need an inline fuel pump now?
#3) Do you guys have any better tuning suggestions other than the MSD box and an FMU?

ANY help with this would be REALLY helpful guys.  I know I'm new to the boards but we've been on this project for almost 4 years now and it's about time to finally get this DONE!  

Any Thoughts?

Dave
