First Mod Help

[Joeballz]

Ok i just picked up a 1993 TT Supra. I have some extra money to throw around so i figured id list the mods im considering, than listen to what you guys have to say. The mods go, Apexi GT Exhaust, Tanabe Downpipe W/ O2 Sensor Simulators, HKS Bov Kit, HKS Super Mega Flow Intake Kit, B&M Shifter, Apexi FMIC Kit, Greddy Front Strut Bar, Greddy Turbo Timer W/Harness, and Greddy Profec B Spec II Boost Controller. These are the mods im considering. Let me know what you think. Some of you might tell me different from what i choose so let me know. Thanks!!!!!

You don't need O2 simulators on a 93.

If you get an aftermarket BOV make sure its recirculated unless you want to run really rich and stall everytime you let off the gas.

The rest of the stuff I don't really have any opinions about. I think I've read that a lot of people don't like the Profec B, I'm not sure why though. I run a Blitz SBC-IDIII myself, love it.

And most importantly... Use the search feature before asking questions, 9 times out of 10, its already been answered somewhere on the board..

I'd switch out the apex'i exhaust for a blitz, VS, or HKS Ti. Also, I'd get a greddy 3 row if I were you. And with the BOV you don't need a "kit" if you have a FMIC. You can get a flange welded onto your pipe and place the BOV on the pipe. Also, you do not need an O2 simulator with a 93(OBD I).

Your list looks good, but like stated before, you dont need the o2 on a 93. You might want to rethink the profec b and go with the sbc id. Do a search on the profec and see what comes up. Alot of people have problems with spiking with that controller. I have the profec a and havent experienced any serious problems. It will spike occasionally, but thats only on very cold days (30-40 degrees)

If you don't install a BCC or some other less conventional way to override boost/fuel cut, you'll hit that every time you step on the gas slightly aggressively. To boost (over stock) or not to boost, that is the question.

[MtFujiSupra]

That's a great list. I got another list for you:
1. Stem seals
2. Head gasket
3. Wheel bearings
4. Control arm bushings
5. Starter contacts
6. Center console lid
7. Hatch rust repair
etc., etc., etc.

Take a look at your prize and ask yourself, where will I get the money (after buying all those toys you listed) to fix the above well-known probs?

After that/\, I would consider getting a better clutch setup, stock one will not hold long under BPU levels, how many miles are on the car??

[Joeballz]

its has about 85k on it

[HaYaBuSakLr]

I have heard the Profec B holds 30+ psi firmly.....hmm....maybe i outta keep my AVC-R instead of going with the Profec B.

[twitch69187]

Timing belt, drive belt, crank pulley, underdrive pulleys, Radiator, new shit that can be done and should be done when you are doing the timing belt, Waterpump??? Just a few things you could do while you are in there. That is if they arent done already. That is what I plan on doing. But as for most of that goes Im pretty sure if only going for BPU levels then most of the stock stuff will do.

You will need a Boost Cut Controller. Otherwise you will hit boost cut at about 15psi.

Get the largest diameter exhaust you can afford. Bigger is better on a turbo car.

Get an ebay downpipe (around $100 or less) dont spend the money on a name brand. It's just a bent pipe for God's sake. Why spend $200 or more? I have the ebay one (megan racing brand) and despite the inevitable, and frantic sounding, warnings you will get from forum members about the O2 sensor studs, mine are FINE.

Get the HKS BOV. Unless you are auto, dont worry about recirculating it...UNLESS you actually have stalling issues when you let off the gas. Mine has never stalled my 6spd Supra.

HKS Intake kit. In my opinion, I dont think it is worth it for performance gains until you get rid of the MAF, unless you want the additional sounds it will get you. But others may disagree with me on this one. Plus i dont think those foam filter kits clean the air as well as a K&N type filter.

Front strut bar. If i was going to get one, i would get the TRD because it has solid mounts on the ends where the bar attaches to the bracket, not a bolt that allows flexing.

Profec B II. I think the sequential twin operation confuses this type of boost controller which has fuzzy logic.

BUT MOST IMPORTANT OF ALL (for those who arent rich) check the "For Sale" section of SupraForums. Most all of this stuff is for sale on there a lot of the time.
