GrandAmSE Posted November 2, 2006 Report Share Posted November 2, 2006 Ok I'm turboing my 3.4 and this is the parts I have. What else do I need besides piping, flanges and a BOV. T3 Turbo by AiResearch Turbo Prix Intercooler Quote Link to comment Share on other sites More sharing options...
kuntzie Posted November 2, 2006 Report Share Posted November 2, 2006 your going to need a tune custom x-over injectors a MAP sensor (2-bar) if you plan on decent boost levels custom downpipe it is alot harder then you proably think Quote Link to comment Share on other sites More sharing options...

Guest TurboSedan Posted November 2, 2006 Report Share Posted November 2, 2006 this is the 2nd time today i've had to move one of your threads to the correct section anyways. it sounds to me (so far anyway) like you have no idea what you're getting into. what you'll need more than anything is alot of time researching this project and ALOT of money.

GrandAmSE Posted November 3, 2006 Author Report Share Posted November 3, 2006 Yeah I know but I'm prepared to learn before I do this. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted November 3, 2006 Report Share Posted November 3, 2006 I would spend a good couple months of research and what EXACTLY needs to be done. This is not something simple. Best thing you can do is research for yourself. Not only is there alot of info here, but on 60*v6 as well. Quote Link to comment Share on other sites More sharing options...

Guest TurboSedan Posted November 3, 2006 Report Share Posted November 3, 2006 PM timg on here or 60*V6 forum. he turbocharged his LQ1. one nice thing about turbocharging an LQ1 (depending on year) is that you can use a front exhaust manifold on the rear by flipping it upside down. that way you wouldn't have to worry about making custom headers/log manifolds or blocking off the downpipe flange. of course, you'd still need a custom crossover and custom everything else for that matter. i'm pretty sure you can't use modified TGP code on a turbocharged LQ1 either - you have to either go with a standalone system like MegaSquirt or an FMU and a something like the Split Second FTC like Tim used. i think he ditched all that recently and went with OBD-2 so he could use a DHP PowerTuner though.

GrandAmSE Posted November 3, 2006 Author Report Share Posted November 3, 2006 Don't get me wrong I not just going to say hmm I think I'll put in that turbo today and go at it. I looked at this flexable exhaust tubing to make the turbo to I/C to TB pipes. I was planing on just welding closed the stock downpipe and then have a flange weld to the exhaust crossover. Do you think I could use the flex tubing to make my down pipe if I weld it to a flange? I'm new to this and plan oon taking it slow. Quote Link to comment Share on other sites More sharing options...
intern8tion9l Posted November 3, 2006 Report Share Posted November 3, 2006 i don't think flexible tubing will give you a smooth air flow at all for the intake, i might be picturing the wrong stuff though. i'd also have a real downpipe fabbed up by an exhaust shop if you want to do it right. as long as you're prepared to spend the money for the project, then spend it Quote Link to comment Share on other sites More sharing options...
kuntzie Posted November 3, 2006 Report Share Posted November 3, 2006 id ditch the 3.4 and go 3500 hybrid IMO easier to work with... and theres a few people one here proving that 1 cam can do the job and some. Quote Link to comment Share on other sites More sharing options...

Do you think I could use the flex tubing to make my down pipe if I weld it to a flange? I'm new to this and plan oon taking it slow. flexible exhaust tubing? are you serious? nooooooo way! you would have major boost leaks using that as intercooler piping, and major exhaust leaks using it as a downpipe (not to mention i imagine it would be loud as fuck and rattle like crazy). you really need to do alot more research. for intercooler piping - buy 2.5" mandrel bent aluminum pipe and either weld them together and/or use silicone straight or 'hump' connectors using SS T-bolt clamps. for a downpipe, use stainless steel 3" mandrel bent pipe and weld on the appropriate flanges and use a flex bellow in the right location. same goes for the crossover pipe - stainless steel mandrel bent pipe (2.25"?) using a flex bellow on each side of the turbo flange. you obviously have alot of homework to do. it really does sound to me like you think you can just throw this all together and get it running within two weeks. this kind of project is likely going to take at least a year depending on how much money you have, how determined you are, and how serious you are about doing things the RIGHT WAY.

GrandAmSE Posted November 3, 2006 Author Report Share Posted November 3, 2006 I'm just throwing out ideas here. So the car I got my STB from had a 3.1 N/A in it. You guys think that would work better? How much (relatively) should a 3.1 n/a run you at the j/y? Since there really isn't a kit and if there was like I could afford 4G's all at once. I'm buying the parts piece by piece. I still have a shitload of stuff I still need and plan on have most of the work done by a shop. I just want to know to a T what I'll be doing so I can say this is how you can do it and don't try to fuck around and have them be like oh the turbos way to small here buy this 3000.00 dollars one. The biggest project I can do in my garage is an enigne swap so if I turbo a 3.1 I could just drop it in myself. Anyone got anymore thread I could read about either turboing 3.1 or 3.4s?

97loudcut Posted November 3, 2006 Report Share Posted November 3, 2006 This thread makes me lol "I got a turbo and intercooler" There is so much more involved in a custom job like this. I hope everything work out for you. Quote Link to comment Share on other sites More sharing options...

I bought one for $35, with a valve stuck in one of the pistons. Also, I've been to a few that wanted $400-$500 for one (too much, IMO). You can do searches too. It's kinda hard given the crappiness of the search function here, but it can be done. I thought there used to be a list of everything you needed from a TGP engine to turbo an LH0, but I may be imagining that. Some people say the T25 turbo on the LG5 is a little small, and it might be, depending on what you're looking for out of the engine. But, for starters, just stick with the stock turbo. Get that running well, then look to upgrade the turbo if you are so inclined. Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted November 3, 2006 Report Share Posted November 3, 2006 Depends. I bought one for $35, with a valve stuck in one of the pistons. Also, I've been to a few that wanted $400-$500 for one (too much, IMO). i'd say $100 tops for a good running 3.1 MPFI LH0 engine. btw, you should be able to find a much newer (and MUCH better) 3400 LA1 engine for $400-$500. they should be easier to find too, since they are newer and availability is higher. and it would likely have less miles and run better than any used 3.1 MPFI engine you'd find. BUT, turbocharging a 3400 will be more work in that you can't use alot of the TGP stuff. fwiw i bought a complete '00 3400 engine last spring for $150. it was blown due to a bad LIM gasket (notorious problem on these engines) but i didn't care - i wanted to rebuild it with forged Wiseco pistons anyway. for $150 it was worth it for the top end swap alone. which is another idea you should really consider - a 3.1 MPFI engine using the heads & intakes from a 3400 or '00+ 3100. they are known as "3x00 hybrid" engines on the forums. btw, i bought my 111,000 mile TGP Turbo 3.1 LG5 engine from the local j/y for $350 and that included almost everything - the radiator, intercooler, everything turbo specific etc besides the turbocharger itself (it was already gone) and they didn't want to sell me the wiring harness & ECM either at that price because for some reason they thought they could get good money for that i removed the memcal when they weren't looking and stuck it in my pocket LOL. you don't need the TGP specific wiring harness anyway - i would just use a stock NA 3.1 wiring harness & ECM with a TGP memcal and you're good to go. the only other thing you'd need to do as far as wiring goes is you'll have to cut a small slot in the MAP sensor connector in order to plug the 2-bar MAP sensor in, but that's hardly a big deal. it took me literally 5 seconds with a Dremel. other than that all you need to do is extened the IAT and O2 sensor wires to the right locations. also, a NA 3.1 wiring harness won't have the boost controller solenoid wiring but who cares when you can use a better $25 MBC instead. btw, that TGP engine i bought ended up having a melted piston so i kind of got ripped off in the end. oh well, that's more my fault then theirs. at least i still had all the TGP parts to put on my Cutlass's original 3.1 LH0 engine. I thought there used to be a list of everything you needed from a TGP engine to turbo an LH0, but I may be imagining that. i'm sure i could come up with a COMPLETE list of things you'd need to turbocharge a NA 3.1 or 2.8 using TGP parts. i'll try to post a list later. fwiw, i do have some of that stuff for sale Some people say the T25 turbo on the LG5 is a little small, and it might be, depending on what you're looking for out of the engine. But, for starters, just stick with the stock turbo. Get that running well, then look to upgrade the turbo if you are so inclined. while the turbo really is too small, it's damn fun on the street because there is almost ZERO lag. makes for a fun car to drive around town in and it's fun in a typical street race. not that i condone that kind of activity yeah, definately start off with the stock TGP turbo. or you could spend $1200 on a ball bearing Garrett GT2871R turbo which will make MUCH more power and be a bolt on besides the oil & coolant lines.

intern8tion9l Posted November 3, 2006 Report Share Posted November 3, 2006 i thought the stcok 3.1 ECM was different from that of the 2.8/3.1T? i mean it doesn't make sense to me, but thats what the computer said when my friend and i looked it up at his shop Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted November 3, 2006 Report Share Posted November 3, 2006 i thought the stcok 3.1 ECM was different from that of the 2.8/3.1T? i mean it doesn't make sense to me, but thats what the computer said when my friend and i looked it up at his shop it's the same - ECM # 1227727. only the MemCal is different which can easily be swapped out of course. my Cutlass still uses its original ECM. as a side note, the early MAF equipt 2.8 might have had a different ECM, and i think the later ('92-'93?) might have had a different ECM as well but i'm really not sure.
