My Car! 1988 Toyota Supra Turbo Targa 5-speed

[Goodspeed]

So this thread has drifted to the bottom because things have largely gone unchanged with the car, but I just started making some money and I have a lot of ideas virtually set in stone I thought I'd run by everyone as this car will hopefully be reasonably different by the fall.

I just turned putting 4k miles on the car this past Sunday (the 4th) since buying the car late last August. So far its been impeccable.

The only things I have done are:

- Swaybars. The Suspension Techniques bars transformed the car, made it much flatter and frankly safer to drive. Low cost plus ease of installation made it a hugely rewarding investment.

- Sumitomo HTRZ rear tires. My pass. rear Yoko AVS became mysteriously flat after sitting overnight in my parking lot, with a small cut in the sidewall. These have so far had much better traction, and they were about 70 a piece. The Yokos are sticky but soft and wear fast.

My plans are as follows (with a few Q's):

Maintenance
- Oil change in 371 miles
- Change trans and rear end fluid. Should've done this when I bought the car but the previous owner took great care of the car as a whole so...
- Paint the exhaust with high-temp enamel. The hanger and muffler have definite surface rust that needs to be taken care of.
- 4 wheel alignment
- Remove, sand, and paint some sun-dried/cracked moldings and body pieces
- Source new or recover handbrake boot, shift knob, and center console cover
- Possibly repaint rear bumper cover
- New front lower ball joints
- Valve stem seals...oil consumption and smoke-upon startup is present

Modifications

Suspension
- Tokico Illumina dampers, TEMS-compatible and adjustable
- Eibach springs

Do I need a spring compressor for this job? How dangerous is it when dealing with removing factory springs/installing aftermarket ones?

Wheels and Tires
- Chromed or Polished MKIV TT wheels
- 245F/275R tires...Fuzion? BFG's?

Interior
- Short shifter
- Autometer electric oil pressure gauge
- AEM UEGO Wideband in A-Pillar spot

Exterior
- Silverstar sealed-beams and fogs
- Fog-light rewire: ability to turn them on independently of headlights

Engine Performance and Misc. Items
- Walbro 255lph in-tank fuel pump
- AEM or Aeromotive rising-rate AFPR
- RC 550cc Injectors
- Lexus V8 MAF from SC/GS/LS400
- CX Racing FMIC (already have)
- 2.5" Intercooler piping and couplers
- A'PEXi S-AFC for injector control
- Magnaflow exhaust tips
- Greddy oil-filter adapter, to install new pressure sending unit. Installs between filter and block (much more accessible)

Two questions: When doing the fuel upgrades, is it possible/safe to reuse factory fuel lines? In essence, just replacing the pump, installing FPR and injectors, but leaving the rest intact. From my research on the MK3 I haven't found an account of redoing the entire system for my simple needs, but I know that fuel system kits (such as for the MK4) include up to 20 feet of stainless steel braided lines. New fuel filter: necessary?

Also, the S-AFC is quite possibly un-necessary. The 550cc injectors are 25% larger than the factory 440's; the Lexus V8 MAF body is 25% larger in internal diameter and volume. The two compliment each other perfectly and it is an old, proven fuel mod by a current Toyota engineer by the name of Reg Reimer. It has been proven to push fuel cut past 19psi from the stock 14; my power goal is 300+whp and as close to 400wtq as I can get, if not achieve. An extra 6+ psi from the current 13 would achieve this I feel; the turbo would be out of efficiency certainly before fuel would run out. Is the S-AFC then necessary for any further air/fuel corrections and tuning? I need to find out what duty cycle the 550's are at when they are theoretically near fuel cut with the Lexus MAF, but thoughts welcome

Plus: what is an injector "clip"? A new clip must be soldered/spliced into the factory harness...why? I know virtually nothing about wiring and electronics.

After this is all accomplished, I feel like the car will be largely done. I see no need to further an already pristine example, and the car is still to this day fast enough. I have made it a point to limit my driving so as to be able to enjoy the car as if it was still new to me, and its still a blast to take the targa off and hit the road. The 4th gen still has my heart, however, and that will be dealt with as well as another, older Japanese classic that I always fall for. With the MK3, however, I'm looking forward to another year (almost) and another four thousand miles 8)
