Hello fellow Lexus freaks.

I’ve decided not to buy headers and other NA parts and have been presented with two turbo options.

OPTION #1, QUESTION
I’m looking at purchasing a F-max kit for my SC 5speed as a starting point, however have come to understand that the 92-air flow meter & computer do not like boost. Can I run a new style AFM or MAF on a 92? Would I need to upgrade my computer to do so?

OPTION #2, QUESTION
I also have a friend who has a complete Automatic Aristro TT front cap who has decided to not go forward with his project GS300. He has offered me the front cap including front larger brakes + 4piston calipers for $3500.00 Clearly this would be the way to go over the Fmax, however I would like to keep my 5speed trans and am not sure If the Computer for the auto & 6speed are the same. Can I run the auto computer setup with my 5speed?

Decisions, decisions……..

Any help would be greatly appreciated.

 

Yes the auto ecu will work with the 5sp tranny.

 

firstly did you mean "front clip"? anyways if you are talking about a front clip, I would not waste my time, the NA is a great starting platform. I also don`t know what you are talking about the maf sensors, I have been running around for a couple of months with my stock maf and b.o.v. venting to the atmo, and no problems so far. If it were me I would get a toyomoto manifold, and a fair sized turbo and work from there.

 

That’s what the guys at turbokits which sell Fmax kits claim. The 92 Air Flow Meter does not perform well with the turbo kit. Yes front clip with struts, brakes and all. I think it’s a fair price + I could sell the TT Auto trans to generate some extra funds. I know the computers On the RX-7 TT's are not interchangable between auto and 5 speed, I herd the same about the Supra.

Thanks!!
