Hey i was wondering whether anyone knows or has done this... is it possible to say go out to a junkyard and ripp a turbo off a car that came factory turbocharged? like an Eagle Talon or ripp it off a 3000Gt and have it work on a Third Gen? Cuz if this works im nott gonna spend the money on buyin brand new ones and just gett them cheap from a Junkyard then plum up my own twin turbo setup..

 

Look for some turbos off a Thunderbird Turbo Coupe. Between 83-86 are the bigger ones. To distinguish the year, look for the hoods with out the scoops built in. These are the T-03 turbos, 87-88 had IHI turbos which are smaller, but they ran better due to the intercooler. I use to have an 88. For a 4cyl., it ran damn good. Put your guns away, but I would like to get another one sometime. It was very easy to pull 300hp out of these, and 400 with N2O, without worries of damage. I had about 200hp, but got 30mpg everywhere. Anyway, look for the older ones. They usualy run anywhere from $50-$100 each. Plan on having them rebuilt, or do it yourself. Its not hard, and the kits aren't that expensive.

Check out this eGroup for McCulloch and Paxton superchargers: http://groups.yahoo.com/group/mcpax. They are working on a project to convert JY turbos to belt drive... Big boost for just a few $$, about $600-$700 for a complete system that doesn't have the problems that current SC's or turbos have. They also have another project (The Terminator) to retrofit existing SC's and turbos, that will provide max boost instantaneously. It doesn't increase boost, it just makes it come on instantly, making it seem like a much larger blower. No more SC or turbo lag. Believe it or not, this uses a JY smog pump! These systems are actually being tested... This group is going to turn the blower industry upside down.

 

OK thanks alot guys.. one more thing if anyone is still lookin at this post... My aunt just totalled her Grand Am GTP and is gonna have it taken to a junkyard and all...Would it be possilbe to take the factory supercharger off her GTP and have it fit my 350??

 

No problem! Bolts right up.

Oh, wait, I should mention that you're going to have to lop 2 cylinders off your block. Sorry!

Hey wasap Warrior. Sorry that supercharger will prolly not fit on your v8. Superchargers are usually designed for certain engines only, whereas turbos can be used on any engine if you can custom fabricate all the piping. The performance you can expect will depend on the displacement of the engine, the compression of the engine, and if the turbo matches up well with that setup. Smaller turbos will generally produce less power than a big turbo but they will spin up faster with less lag, so its kind of a tradeoff. I would say a good bet for junkyard turbos would be the old Buick turbos from the GN's ... those should work well. Good luck!!

factory turbo's are made specifically for the rpm range and size of the motor they are attached to.. you might blow you're motor if you don't know the specs of the turbo.. if you get a small turbo, the nozzle area controls the speed that u'r turbo spins at.. smaller the nozzel area, the faster the exhaust will have to go through cuz it's pushing harder.. and if it's off a talon or whatnot, which is a 2.0 Liter.. well.. now you got 5.0 or 5.7 liters going through it.. so it will go nuts.. to fix this you have to have a waste gate or pressure release valve.. or you change the turbo's housing to something bigger to slow down the turbo and let the exhaust go through easier.. and you'll get MAX boost at a low rpm (which is good for street, i guess.. but not really for track) now on an aftermarket turbo, you can pretty much always find the correct size of housing for you're application.. but on something factory it might be hard. and then there's all the manifold/headers to remake and such..
a good book, i've found to read up on this (if you want to go junkyard turbo) is "Turbochargers" by Hugh MacInnes..

where did you find this book at?? Just go to any book store and they will have it??

 

i found the book at a speed shop.. they usully have books on motors and carbs and such there.. found a turbo in the back, they might have some at BIG bookstores under the car section, but i'm having a hard time finding one on superchargers (specific) in bookstores.. so i'm going through the speedshops.. just ask at the counter, they might be nice enough to point it out for you
one thing that i've been told cuz i've asked the same question about junkyard turbo's. they've told me (the machanics and ppl who street race (and with some kinda "why would you bother with a junk turbo?" kinda look)) anyways.. if anything a turbo off a Diesel motor would be the best choice.. with some housing modifications and such..
neways.. don't be afraid to ask questions at speed shops and such.. cuz they want to make money and want u to like them so you pick them.. neways.. what's the fun in having somebody else do you're mods, eh?.. heh.

Try a pair of Nissan 280Zx turbos.
It's about half the size of a 5.7 V8
So a pair (twin turbo setup) should be about right.

 

No one uses housing size to control boost, you use a wastegate. I also can't think of any situation in which having boost at lower RPM and holding it across the rev range is bad. Drag racing is more about area under the curve than it is peak numbers. The main considerations when choosing a turbo: Will it provide enough airflow for my engine? Will it be efficient at the boost levels I intend to run? Will be sized so as to have a reasonable boost threshold? Is the hot side efficient enough to not pressurize the exhaust manifolds excessively?

That being said, the T03's off of the thunderbird turbo coupes seem to do well on a mild motor, a pair of GN turbos would do well on a more modded motor.

 

Warrior,

That Grand Am GTP has a 3.8L V6. 240 hp @ 5200 rpm
Right?
Non supercharged were rated 200 hp so it is only a 20% hp increase.

Boost is probably around 3 psi

Of course it is possible to put it on your 350, but it will require a lot of custom parts. With a different pulley it could probably flow air for 300 hp, not much more.

If you can get it for free then ship it to me if you don't want to keep it

Might put it on my lawn-mower or something ...

I have a turbo off of an 89 Turbo Coupe. My plans changed so i don't need it. All seems fine with it, no play and is pretty clean. Email me if you are interested.

 

how much would you sell it for Omega?? and you only have one correct??

 

what about quad-turbos that would be cool so has anyone ever done this i would like pictures

 

mike moran did a quad turbo setup in his fourth gen camaro but never got it down the track. he burnt up clutches left and right and decided it wasn't cost effecient. he was trying to sell it but i think he ended up just dismantling it.

 

Holy back from the dead Batman!

 

didn't even realize that this hadn't been posted in since 2001. atleast i wasn't the one who brought it back.

 

i did a search on turbo chargers and this came up and i didnt realize it was that old until i already posted it

 

saab 9000's also used t3's, some are water-cooled and have an adjustable integral wastegate.

 

Okay I know this is a really old topic, but I have to point out a mistake in it.

The Grand am dose not a GTP model, nor did or dose it come with a 3.8v6, your thinking of the Grand PRIX witch had the GTP and the 3.8L engine (in SC and NA form.) Also was the Buick Regal GS, the Monte Carlo SS (I belive either 2000 or 2002 and up had the SC) the Impalla SS the Bonneville SSEi, the Buick Riviera, the Buick Park Avenue Ultra and I think thats about it. The specific supercharger used on the series 1 3800 L67 was an eaton m62 the series 2 L67 was an eaton M90, there are after market shops that have modified the M90s to use the rotors out of M112s (what is used on the SC Cobra IIRC)

Just had to point that out... sorry for resuercting this post, but I didnt want some one to go out looking for a grand am gtp and make a fool of them selves.

 

The confusion is prolly the GRAND AM GT, vs GRAND PRIX GTP

Also, the bonneville SSE has the same motor.

I used the FPR from a '99 GTP for my car. (singleplane EFI)

Looks like an old topic, but I just thought I'd mention that I'm in the process of doing a JY twin turbo buildup on my mustang. Using the turbocoupe "super 60" .60/.63 turbos somebody else was mentioning. Turbo's on a fox body is waaaaaay easy, not sure about thirdgens but it couldn't be that much harder.

 

Oh yes, I forgot about the SSE having the option to have the supercharger

I'm planning on turbocharging a 4.3 89 blazer in the near future, hence my sudend intrest in turbos. (i'm normaly a superchager guy, but I can get used t3 turbos off ebay fairly cheaply) Thinking of doing the remote mount thing.

Basicly I just want to have around 300-350ish TQ at a realitvly low RPM.
