I saw the pictures of Lex' supercharger setup and had a few questions about that and management issues. People seem to suggest piggyback up until 20psi, but what exact piggybacks are being used here? Will an SAFC combined with an ignition modifier do for fuel and timing? Also what is the Maf setup thats used in Lex' car? Is it hardwired into the stock setup or is it using a translator? I am basically trying to figure out the supercharger setup to create roughly a 550 rwhp setup using the 1uzfe in a 1994 LS400. That combined with the V160 transmission from the Supra TT. I hope some of you can offer suggestions towards this setup and its management. ALso, what are the stock limitations of the bottom end's internals, "pistons, rods, bearings" also where can I obtain a metal headgasket, and reinforced head studs.

The bracket will work on all uzfe engines. I have not test it out, but i have eye balled. They are all have the same stablizing points. To you questions, the bracket would work on the 95 LS400.
I am sure the ecu is different between 94 and 95 in some ways. All about Apexi piggyback http://www.lextreme.com/piggyback.html
I am using a piggyback called Splite Second. This unit was made specially for 1uzfe engine. This was a custom made for my car and i really like the laptop programbility and exchange of tuned programs amoung the FI 1uzfe owners. I hope everyone get this piggyback so we can share and help out each other via email attachment. Secondly, i also like the timig control which most piggyback done have.
Lexus 1UZFE uses Karman sensor. I have most of the parts u need to engine upgrades.

Would I be better of using the split second fuel/timing calibrator than an FMU, like the super afc like on your twin turbo set-up.
SAFC is a better choice than a straight out FMU i.e. 12:1, SAFC allows you to fine tune the fuel settings slightly more than an FMU that is a hardset equation. SAFC-2 also allows for knock monitoring and several other features not found in the first SAFC. As always, stand alone rules all, but for the money just get an SAFC, no point spending massive cheddar on a fi setup and then cheaping out with an fmu.
