The Official BXX's 90 TGP Project Thread

[BXX]

Figured it was time to make a thread


This of course is aboot the continuing madness of my TGP. For those who don't know a bit of history of the car...

This used to be Psycomatt's old whip, which was sold to Jonpro. From there, Jon ditched the LG5 and went for a LX9 Turbo running Megasquirt. Unfortunately, having used the stock LG5 manifolds (think tiny ports) on the LX9 (think big ports) and a GT3076r turbo, it blew headgaskets. Replaced those, retuned a bit, and they didnt last long. Jon gave up, said the hell with it and I made a joke to sell it to me cheap one night in chat... Well, that's what happened. Sold to me, and delivered from outta state I have a 90 TGP that's basically a basketcase but not rotted out (sans the usual hidden quarter issues)

When I finally rolled it into my garage, I tore into the engine. I found the headgasket not blown, but burned through. After actually paying attention to the TGP manifolds on there, I noticed the redish-white hue. BINGO!! Cylinder temps were sky ass high causing the HGs to burn through. Couldnt flow enough exhaust gas out the small TGP manifold ports, so the cylinder temps just keep going up under ~8psi of boost.


Right now the car sits as a shell currently sporting all the body panels though. I can't remove them and start on the rust repair and body work until I find a place to put them.

Current progress is welding all un-needed holes in the engine bay and removing a welded on firewall bracket and removing the battery tray and getting that all covered up, followed by primer.


Sunday I scored a 284 setup from Pullapart. 92 GTP with 127K on it and a bad engine. I snagged the trans, mount, axle stub shaft, trans to engine bracket, shifter, cables, column and bracket and pedals, and all clutch hydraulics for $132! I'm gonna buy the flywheel, axles, and clutch new. Spec stage 3 will do nicely. Clutch line is getting replaced with braided stainless hose. Looks nice and lets me route it differently.

I just finished modding my firewall plate tonight, it's clean up. Gotta weld some steel in to cover up the hole's left from the A/C evaporator core block.


I'll get some pics up tomorrow and keep this project rolling, it needs to be done by next summer.

For those of you who haven't tuned in to my of my rambling..

-90 TGP
-LX9 3500
-284 5-speed
-GT3076r turbo
-Many suspension mods


Pretty much the simple cliffnotes on what's the madness in process

[Psych0matt]

did you decide what to do with the front clip/body kit? I was pretty set on doing a TGP front swap on mine, but the more I get mine looking better, the less I wanna do that.

[BXX]

Yes, I'm prolly gonna rip of the existing shittastic later year like 96 bumper and it's going in a dumpster.

I'll need to source a TGP bumper, and header panels and headlamps and such.

[Psych0matt]

I has most of that. It would need paint, but it's sitting in the garage. Could use the bumper lights, but I believe the sedan ones are the same.

Chow much?? BTW, since shipping isn't gonna happen, how far are you from me again??

[Psych0matt]

I wanna say it was about 3-4 hours (taking our sweet ol time). Are you keeping my old wheels, assuming you still actually have them? I would potentially trade those for the clip and header panel. otherwise I wouldn't mind making a trip out some weekend for the heck of it, I'd probably say cover my gas and like $75 ish? We can work something out if you want

[BXX]

Actually, these old wheels arent gonna do me a damn bit of good.

So yeah I can trade for the TGP bumper and header panel

[Psych0matt]

why wont they do you any good? But yeah, that would most likely work for me.

[BXX]

Cause 16"s are for stock economy cars


Yes, the TGP may see 20's. More than likely 19x9"s though. Depends on what I find.

And im not sure if Im gonna get off my lazy ass and touch the car today. I just feel wore down from work lately..

[xtremerevolution]

So Bob's finally coming after the GSX. If you pull this off, you should have no problem overtaking me in a straight line or around a corner. Good luck. I'll be watching this thread.

[Addicted2bass]

Looks like a sweet project! Should be sick when it's done. I will be keeping and eye on this thread for sure.

Here's some progress from today. I still need to deal with the battery tray, but it was lunch time From there i need to buy some sheet metal to fill in the A/C portion hole in the firewall plate and to do any patch work from where the battery tray was.

-Some of the 5 speed goodies I got


-How the car resides now, on 4 jackstands as a shell of itself




-Some chasssis goodies. Still need to trim the LCA bushings to size. I'll do that once the cradle is in.


-Modded firewall plate


-Top of the core support has un-needed holes welded and ground. I'll do the front once I deal with the bumper and stuff


-And some further progress. Just trying to make the final result look clean and no so cluttered.


















BTW, I'm thinking of painting the car pearl white.

I imagine you are relocating the battery. You could probably pull off at least a semi-shaved engine bay.
