fuel system

[sketchymechanics]

ok, I am new to the lexus world and am needing a little input..

I just got a screamin deal on a 92 sc400, she runs well, but needs a little more poop, and I just happen to have a t-62, bov and wastegate.. that have been removed from the turbo camaro project and though I swore to myself that I was gonna just leave this alone.. I can no longer fight the urge..

questions..

1. what do you guys do to get the 10.3:1 comp ratio to take more than 3 psi?

2. what modifications need to be done to the fuel system?

3. where do I find build up parts for the transmission?

4. someone please give me a solid reason not to do this to an otherwise perfect lex..

Thanks in advance

Hey Welcome... this forum is specialized making perfection cars to monsterous cars.... Do u plan to run 3 psi only? Fuel will be ok if you run 7 psi or less. Supra Auto trans are same as SC400 Tran and few trans avialable to the SC400.

10 psi intercooled would be about my target, what kind of longevity can one expect?

3. If your speaking of a manual tranny, heres a place to start, W58 or R154 bellhousings from Supras. The R154 is slightly beefier and stronger.

4. Depending on your turbo setup. Are you willing to give up your A/C and PS?

And as far as longevity. No one really knows the duration life of a Forced Induction motor. But the first thing I would do to any FI is add a copper head gasket. Also remember the thicker you go the tighter the timing belt becomes. & can throw you off a few degrees when tuning it. I also remember Lex saying to also double the lower intake manifold gasket if adding a thicker MHG. hth

na, gotta keep a/c and p/s, if need be.. I will mount the turbo incon style under the car.. there are some guys down here "remote mounting" turbos http://www.ststurbo.com this may deserve some looking into, I am not a big fan of remote mounting, but I really dont want to hack and slash this car, I kinda like all the ammenities..
