I know about the post count thing man, im just saying, usually people new to forums in general, are pretty new to the car. Not even supra specific. Obviously in this case i was wrong. But yea your on the right path. The studs are def the way to go. If i may ask what version of fcd did you buy? I have one that is said to not work well with mkiii's but there is a version that is suppose to work pretty well.

Yes its the K3 that works with mkiii's. Sometimes with hpf you have to be real specific with what ur asking for. I was once told that underdrive pulleys WOULDNT require new belts lol. Oh oh and when i ordered my plugs from there site, i specifically called and asked if the part number i was ordering was all 6 plugs, he said yes, today i recieved my package... Guess what... Only 4 plugs as expected lol.

As far as the walbro. The 255lph is what ur refering to. The 255 is the one ur going to want. Im not sure if it requires a new fpr, maybe someone else can answer that, i think it does though.

Well if you boost 15-20 psi on ur stock turbo you aren't going to have a turbo more than a week, if that. The stock fuel system can handle some power but if you upgrade the fuel pump, you might as well upgrade the injectors to 550cc. And it would be a very good idea to look into a fuel pressure regulator. Aeromotive regulators are a popular choice. Also to get more air in, you're going to need to buy a Lexus LS400 AFM. Not sure of the year but it's an older one. It's just a bigger housing that allows the stock AFM sensor to bolt to it.

i have a t3 used on a thunderbird i could use if needed it should bolt up. and i was looking into injecters when i got the FP... so i should not boost 15 yet.. i should do 10 and wait until i do a bigger turbo. sounds good. as for HPF dave is the best person i talked to as of now. chris was a lil slower on supras but i still got really good service. spending 600.00 i better. now im just waiting for all the parts to arive and i will back on the road.

redmaro · 04-19-2007, 04:31 PM

I think the stock turbo is only good to about 14psi. Good luck.

Supra_87_mk3 · 04-20-2007, 03:25 PM

ight thank you. so i wont be running high boost until i get a bigger turbo... do you think i should go ball bearing or not?

i dont know much about turbo's this is my first one all i know is i am learning somthing new ever day.

im low on cash for a while b/c of my new upgrades. so it would be a while b4 i could buy a ballbearing turbo...there so much money...also any good brands to keep in mind?
