hey im planning on building up my 95 GPse into a turbo car and i was wonderin if anyone had these parts! any help would be awesome.

Rear exh manifold
downpipe
charge tubing
turbo
tgp map (one that senses boost)
HM-282 or HM-284
computer (or can i use my stock one with a chip?)
crossover
Intercooler
Oil lines
and any thing else i would need!
thanx for the help!

There are two TGPs that are currently being parted out.  Take a look.  :icon_rolleyes:

your swap would be a little more involved due to your car being a '95 with OBD-1.5 electronics.  you can't use your 3100 'L82' since for the most part none of the TGP parts will bolt onto it, so you would need to get either an '89/'90 'LG5' VIN 'V' TGP engine or an '89-'94 'LH0' VIN 'T' 3.1 MPFI engine.  you could also turbocharge an '88/'89 2.8 'LB6' VIN 'W' engine with TGP parts.  i myself just turbocharged a regular '91 3.1 MPFI 'LH0' engine with good results.

besides the stuff you listed above, you would also need:

- TGP wiring harness but only if you want to use the wastegate solenoid.  i would just use a regular 3.1 VIN 'T' MPFI engine wiring harness and a $25 MBC.
- the OBD-1 1227727 ECM since your car is OBD 1.5
- TGP engine oil pan or get a regular 2.8/3.1 oil pan modified for turbo oil drain
- turbo coolant lines including the water-to-oil cooler (it's part of the system).
- TGP radiator and upper radiator/intercooler mounting panel if using the stock TGP intercooler
- not really needed, but TGP intercooler fan
- TGP plenum, or just have a regular NA 2.8/3.1 plenum drilled and tapped for the MAT sensor

there may be other things you need in order to do the OBD-1.5 to OBD-1 swap, i really have no idea there.  also, adding a 5-speed to a '94+ W-body is kind of a bitch compared to adding a 5-speed to an '88-'93 W-body (due to the clutch pedal).


i have a TGP engine oil pan, TGP intercooler, TGP intercooler fan w/wiring, and the TGP water-to-oil cooler if you're interested.  just PM me.

well i can fab stuff up cuz i would like to use the "L82" what wouldnt fit?

pretty much nothing.  the exhaust manifolds would bolt up but the port shape is different so you'd have to grind ALOT of material away and the TGP exhaust manifolds would likely be prone to leaking and/or cracking at that point.  if you were to do that you could probably use the TGP crossover pipe, turbo and downpipe (then again the TGP downpipe bracket won't bolt up to the rear 3100 head), otherwise nothing else bolts up.  not even the oil pan.  about the only TGP parts you could use when turbocharging the 3x00 engine would be the radiator & intercooler.

if you wanted to turbocharge a 3x00 engine i would consider the '00+ 3100 'LG8' or better yet the '96+ 3400 'LA1' engine over the '94-'99 3100 'L82'.  it will cost alot more then swapping out to the older 3.1 MPFI engine and turbocharging that, but if you can fab/weld then you have it alot easier than most.

I have said it once so I guess I need to say it again. Do not  post information you don't know for a fact is true.  :bash:

TGP exhust manifolds work just fine, no cracks no leeks. I know for a FACT they will work on the 3100 and 3400. Mine have been through the ringer and they aren't cracked and they don't leak. Yes you have to do some serious grinding on the lower part of the D.

The TGP down pipe bracket will fit to any 3100 or 3400. It helps to use bolts.  :laugh:

Oil pan, if alum in 95 it will eaisly accept a drilled and taped 3/8 pipe for the oil return. If it is steel than you can put a tgp on it.

Say it here or don't say it.

hey thanx for helping me could i use a mill to make the D port or would it be better to use a rotary tool?

You would spend allot more time setting up the mill than it would take to grind them. (conventional mill I assume. NC would be a programming nightmare.)

You have to gasket match the port and then blend it into the manifold chamber. If you went straight in on the D you would go through the manifold about 3/4 in. :icon_frown: About a 4 to 6 hr job depending how many times you stop for a beer.  ;) That includes smoothing out the whole manifold and grinding the ends round. There is allot of cleanup you can do on these manifolds to make them flow better.

i wasn't referring to you Jud, i was reffering to pics others have posted on v6z24.com and domesticcrew.com.  from what i have seen there is no way i would attempt it.  sure it works, but i guess i consider it a hacked fix (no offense) considering there is so little sealing are after grinding them out to fit the port shape.

not on the heads that were on my 3400 IIRC; there were NO holes for the downpipe bracket to bolt to.  there may have been one for the alternator bracket, but there was no hole on the other side.  if you want to bolt up the TGP downpipe using only one bolt i guess that is your choice, but again i consider that hacked.  but who knows, maybe your heads were a different casting # and you have both holes?

i would check out v6z24.com and domesticcrew.com about using TGP manifolds on 3x00 heads.  there are ALOT more people there that have turbocharged 3x00 engines.  this forum only has a few.  most people will tell you it would be a better idea to use a '94-'95 log style rear manifold and cap off or somehow remove the downpipe outlet before attempting to use the TGP exhaust manifolds.  don't get all of your info from one source, just do some research before you start grinding.

Jud, why not post pics of your exhaust manifolds so we can all see?  i'd also like to see pics of your TGP downpipe (the one you had to grind out to accept the larger turbine wheel of your new turbo).  i myself would rather just buy 3" V-band for the downpipe than start grinding away a ton of material, but if you could post pics maybe you could sway me into doing what you did.

ok ill do that! thanx :icon_biggrin:

my mistake, the holes are actually there, but in their place are studs for the ICM/coilpack bracket to bolt to.  you could relocate the coilpacks, or there might be another way around it.

I have a T25 that I am not using PM if interested.
