cryptnix Posted November 4, 2004 Report Share Posted November 4, 2004 :-) Yeah. I already have the turbo. Only thing is I've asked this question before. But with a motor thats got 140,000 miles on it is it TRUTHFULLY worth my time? I don't plan on putting any type of strain on it as 6 to 8 is pretty much the max. 6 psi is fine with me but, as far as the computer goes what options do I have for my motor?! It frustrates me that not really anyone updates these ODB 2's for our cars... If anyone can enlighten me then awesome. I have things in order, and a friend helping me out with my manifold, so, if anyone dares to help me and point me in the appropriate direction please tell me. All my issues with my girly girl seem to be free now, after lots of lots of money lol ... grr, but i want some more performance and I want to just do it for the honest hell of it to learn more about turbos. So, other than that guys ... I know my compression is alittle high for a shot but ... Give me your information ... I understand most, if not all of it. If I successfully do this I may just consider a 3400 turbo setup, or better yet a L67 with Twins on it. All in all... 1. I am prepared to be flamed by idiots who think I am not going todo this. 2. The probability of blowing my motor. 3. The 3100's/3400's are cheap now a days so ... its no biggy. It's bound to happen with its current state, so, why not get more umph out of it! What I need to know ... ... is fuel management. ... spark timing, etc. So really, the information I need is from you turbo boys... so, I'll be waiting for your posts.

jeremy Posted November 4, 2004 Report Share Posted November 4, 2004 keep a running tally of the your total $ spent...if it is cheap enough, I (I really mean you, me and your buddy) may have a project for next summer... Quote Link to comment Share on other sites More sharing options...

sl3196 Posted November 4, 2004 Report Share Posted November 4, 2004 Don't know how to set-up the computer stuff but if your dumping alot into this turbo set-up I would tear the engine apart and rebuild it. Quote Link to comment Share on other sites More sharing options...

gp90se Posted November 5, 2004 Report Share Posted November 5, 2004 if you want to do this, truthfully, put a 3.1 wiring harness on it and rewire the interior to work with it so you can use a TGP chip, just to start. if you can get that part done, im sure people will be willing to help with turboing it. if you do go that route, a 3.1 chip will run the 3100 fine.

Canada Posted November 5, 2004 Report Share Posted November 5, 2004 First off....buy the book Maxium Boost.....a guy by the name of Corky Bell wrote it.....its not to the engineer's level...which is nice. That is simply the best source of information you can get......everything that I would tell you is a repeat of that book. As far as your controlling setup goes.....if you go with an extra injector controller (Simple Digital Soultions has a nice unit) you can use that to control fuel under boost. And you really don't have to mess with timing with only 6 psi...you could to make a few more horises, but its not manditory. Quote Link to comment Share on other sites More sharing options...
cryptnix Posted November 5, 2004 Author Report Share Posted November 5, 2004 wow, you two ... i love ya for the info ... i was thinking the 3.1 comp cause then i could get rid of my catalytic inverter. i just want to see if its worth building the 3100 to spec for a turbo setup ... or if i should really just waste the cash on a 3800 swap ... the 3800 to me though is so much more pleasing to my head being in all on how much it has for aftermarket.

gp90se Posted November 5, 2004 Report Share Posted November 5, 2004 now who in the sam hell would want a boat anchor under their hood (Chill, i still got love for the l67) build a crossover, downpipe, weld the rear manifold shut, put some pipes on, an intercooler, a BOV, wastegate, your turbo, wire it up for MPFI and toss a TGP type chip into it, you will have the workings of a 3x00 turbo car. given thats a VERY simple and basic list, But thats where you'd have to start. Figure out if the 3.1 harness will work with the firewall plug, and if not, convert the SFI to MPFI (instructions are around). Theres a lot more advansed stuff on how to do all of this ( 3 bar map sensor, transmission info, TUNING!!!) but ya gotta start somewhere. Good luck Quote Link to comment Share on other sites More sharing options...

Good luck :withstupid: that is almost exactly what i am planning on doing, only with a 3400 & a Getrag 282. there are 3400's with fairly low mileage on ebay going for $200...just a thought. also, you will probably have to swap out your current 4T60-E for an older 4T60, since the E is electronically controlled. the TGP memcal cannot control it. or just swap in a Getrag.

EurosportZ34 Posted November 5, 2004 Report Share Posted November 5, 2004 wait....your going with the automatic 4T60-E still, right no tranny swap? well if you are going to a manual try getting a 284, with all the extra power you'd be having the 'lil 282 wouldn't hold up i wouldn't think Quote Link to comment Share on other sites More sharing options...
gp90se Posted November 6, 2004 Report Share Posted November 6, 2004 also, you will probably have to swap out your current 4T60-E for an older 4T60, since the E is electronically controlled. the TGP memcal cannot control it. or just swap in a Getrag. almost forgot that, the TGP chip wont support a 4t60e tranny without changing code, and I dont think that has been done by anyone yet. well if you are going to a manual try getting a 284, with all the extra power you'd be having the 'lil 282 wouldn't hold up i wouldn't think the 282 can be rebuilt if needed, and turboZ24 is running 12s with one. the 284 weights more and needs to be sent back to the company to be rebuilt if needed. my opinion, stick with the 282.

Jcrow Posted November 8, 2004 Report Share Posted November 8, 2004 Check your compression. Mine has almost 250000 miles and it has 147 psi on all 6 cylinders. I am going to use a grand national turbocharger with 3800 series II injectors (22lb/hr) A TGP chip with the EGR disabled (The TGP has a different EGR) and a volvo inter cooler. All I need now is a seal for the turbo and some exhaust parts. Quote Link to comment Share on other sites More sharing options...
Canada Posted November 9, 2004 Report Share Posted November 9, 2004 With no EGR you'll have high NOx emissions and slightly worse fuel economy. Like a forced induction guy is really worried about that. Quote Link to comment Share on other sites More sharing options...
manitcor Posted November 9, 2004 Report Share Posted November 9, 2004 if your running ODBII DHP may be able to tune your PCM for you. You will need larger injectors however your stock iginition system will be sufficiet for your level of boost. With the ODBII you can either stick with your stock t60 trans or upgrade to a t65 if you upgrade the PCM to an 00+ PCM. Like posted before, pick up maximum boost. This isisnt something you can just throw together from random spare parts and expect it work. Quote Link to comment Share on other sites More sharing options...
Canada Posted November 9, 2004 Report Share Posted November 9, 2004 DHP work with you? Ha. I've been after them for over a year to make a PCM for the Beretta. Quote Link to comment Share on other sites More sharing options...
manitcor Posted November 9, 2004 Report Share Posted November 9, 2004 DHP work with you? Ha. I've been after them for over a year to make a PCM for the Beretta. it depends, there are slight differences between PCMs even among w-bodies (and certainly between different bodies). These differences makes it more of a development matter to get a tune working on your car. HOWEVER if your ODBII pcm in your w happens to be the same as a supported PCM in the car list then DHP should be able to make the neccassary changes for you.

Canada Posted November 10, 2004 Report Share Posted November 10, 2004 Well......they make a reflash for 97+ V6 GAs (N)..................I can't think of a reason why a 1997 GA 3100 would be any different than a 1996 Beretta. Quote Link to comment Share on other sites More sharing options...
manitcor Posted November 10, 2004 Report Share Posted November 10, 2004 as Ive come to find out there are subtle differences between PCMs even in the same model year or between trims that makes this diffcult. DHP provides tunes only for the GAGT because the 3.4 SE while having the same engine for some reason the PCM cannot be upgraded with the DHP tune for the GT. To make the changes neccassary for the flash to work on a particular car there is an R&D effort involved. So of course the business must factor in resources, cost, etc in determining what cars to support. It sounds like BS I know, but I do software design for a living so I can understand how this can be a problem. Espically considering that GM doesnt release alot of info on these little boxes. Most of what has come to be is a result of years of reverse enginnering. Quote Link to comment Share on other sites More sharing options...
