1sickhb pm'd and asked for a specific part list for a 300whp Celica. I will start a list here and others can add or critique mine:

(assuming 2nd gen)

1. MR2T tranny, MR2T inner axels, 89-91 v6 camry outter axels (I have also heard that alltrac outters will work).

2. Upgraded turbo kit. T3/T4 hybrid or TD06 are probably the most common upgrades. Also, get an external waste gate. A tial 38mm or 44mm are good choices.

3. Stand alone engine management. There are alot of choices out there. Some examples are Hydra Nemisis, Autotronic, AEM, Haltech, SDS, Tec3, etc. Each have pluses and minuses that you should research before buying however most will do the job. The best thing to do is pick one that your tuner is familiar with. I would not go with a SAFC or other black box for tuning. Again, some will disagree here but its a safety issue. There are some hybrid black boxes out there that come close to having all the features of a standalone but the prices approach the cost of standalone. An example is the SMT-6 or SMT-7 systems.

4. Minimum 550cc injectors. If I were doing it, I would go at least 720's.

5. Upgraded fuel rail. Wolfkatz, ATS, ChrisK, Hux, etc.

6. Adjustable Fuel Pressure regulator

7. Supra TT fuel pump

8. Front Mount Intercooler. Again, there are many out there that will do the job. Search for a thread that Manny posted (Presure2) about selecting an intercooler.

9. Intercooler piping

10. Water injection system. Joe O. or Aquamist are good choices for the 3sgte.

11. At LEAST a FULL 2.5" exhaust. If I did it over, I would get a 3" exhaust.

12. A good tune by a knowlegable tuner - an abosolute must.

13. Guages. Boost and Oil Pressure for sure. Others to consider are EGT, water temp., wideband, and knock sensor. There are many different brands including Apexi, Greddy, and Defi. These are expensive but accurate and reliable. I went with autometer. I am not sure I would do that again.

14. Upgraded clutch. I would go with a Clutchmasters or Spec. If you are looking for a stock feel and do not plan to go much over 300whp, I would recommend a Clutchmasters Stage 3 or Spec Stage 2. If you are going for 325-375, I would go Spec Stage 3.

Some would argue that the FMIC, FPR, Water Injection, Stand alone EMS, Fuel Rail, external waste gate were not totally necessary. The fact is that you COULD get 300whp without any of them. However, IMO its not a good idea. Other considerations are lightened flywheel, aftermarket intake manifold, cams, steel head gasket, ARP studs, and forged internals. Again, not necessary but most would provide a larger safety margin and some would give you more power.

If you have an ST, I would definitely get a brake upgrade. Suspension modifications are also a good idea.

Finally, RESEARCH, RESEARCH, RESEARCH. Do not merely get something because someone else has it or recommended it. Check with multiple sources and draw your own conclusions. There is a lot of misinformation out there and it is your money. That advice applies to this post and other recommendations that I have provided as well.

If you know your goals are limited to 300whp, I would seriously consider a 3rd gen. - but there are disadvantages to that as well.
