Quick video showing how quickly the turbo spools and hits fuel cut, have to find the over boost problem.
Thinking the waste gate is stuck shut.

Weighted gear knob, 93 shift assembly and baseplate. Will be looking
At possibly raising the baseplate if the cables allow. I also have the 205 cables I could possibly use if needed. URL=http://s1324.photobucket.com/user/Celicaovertriped/media/F169B839-A46B-41FB-B460-0EFE25C22593_zpstpgzfpb4.jpg.html]Image[/URL]

Installed the 93 shifter assembly and base plate... Wow what a difference! Clutch still needs bleeding and adjustments.
Fixed the over boost issue, was a vac routing problem causing the WG to not open. Had an XS turbo BOV kicking around so I slapped that on, need a stiffer spring because it likes to chatter... Works fine though for now. Sun roof delete completed flame away idc :P Image
Video of me messing around, still need to get used to the light weight flywheel, and brakes. Her first donuts!!!

Not bad, I was left foot braking to initiate the spin, will be a lot easier with the stiffer RSB and LSD. I don't like using the hand brake, but I'll prob install a hydro brake while I'm redoing the lines to the rear.

You really have to think about how your using the brakes and clutch... The car will understeer like a pig if your doing it wrong. On the other hand if you get it right you can drift for days with minimal counter steer.... Wish I had videos of my st165, that thing was a beast in the snow.

Still waiting on my fabricator to fix my floor. Decided to remove the stock fuel tank, get a fuel cell, AN fittings up to the fuel rail, adjustable FPR, new brake lines to the back. Possibly a rear diffuser once it's all together. Have been fighting the wiring harness and ecu after hooking up the obd1 data streaming. Car will not run properly, won't idle, is misfiring and over fueling. Checked over the pin outs 3 times, replaced plugs, cap... Will try to diagnose it further. Leaning more and more towards investing into a Haltech ecu, 8 foot flying lead harness, and a race pack. Want to just be done buying gauges and dealing with electronics once and for all. Plus the stock ecu likes to run really rich under boost and there's tons of room for improvement, really being held back. :shoots:

In other news I picked up another ST185: 1991 red car that's rusted, blown up, and has a sheity black paint job. We have already pulled the engine, and rear subframe. Next set is to fix the rusts, and prep the chassis for rallying.

Do you have any pics inside of the new sunroof panel? I am still leaning towards making one out of fiberglass but I would like to see more of yours. I am about to drop my rear end today to put in the 205 subframe.

Picked up a set of high lift rev3 HKS 272 Cam shafts
Image
Image
plan to eventually drop them in with uprated springs, retainers, and shim-less buckets. Still undecided on which springs and retainers to get. Decided on ATS adjustable cam gears. Cusco type 2 underbrace is on its way, rear end soon to be replaced.

Washed out the inteior with soap and water yesterday and scrubbed with a wire brush. Residue from the sound deadener remains and also the seam sealer. Thinking soaking the stuff in K1 will take care of it. then im going to remove the unnessary brackets on the floor pan for the rear seatbelts, and seat. lightly sand and clean up the metal for fresh black paint. A friend is going to be welding the floor pan and rear end for me, my machinist was too busy and bailed out.
