Message:: [QUOTE="Dr. Jeff Harper, post: 538980, member: 22311"]My drag racing Familia weighs 875 kilos and now has a new "3JZ" (1JZ cylinder head+ 2JZ block = 3JZ !) with 264 cams, Wiseco forged pistons, a single Holset turbo, 800cc SARD injectors, all controlled by a MicroTech ECU (tuned by MacTec). It uses a modified Toyota A342 automatic transmission and high stall (4200 rpm) torque converter from MV Automatics in Australia. The entire brake system is new.  The rear end is a Nissan truck unit with 4.33 gears and a spool.  I use Goodyear racing tires on Centerline wheels.  With the old 1JZ engine it had a best of 10.70 e.t. at 215 kph. My goal with the new engine combination is a 9.90 e.t. at around 225 kph.  This is a bracket (11.90 or 10.90) or "Pro Truck" index race car.  The object is to be able to consistently and reliably run exactly on the e.t. index in the bracket.  It is not designed to see how fast or quick I can make it go.[/QUOTE]
