the machine work was done at Calvert precision engines in denton texas. he builds mostly pro mod motors, but he has done many import engines that made alot of power and are daily driven. like an 800hp 300zx that has been daily driven for 3 years.

machine work and assembly was $1700
stock sr20det long block was $1200

grand total- $6475

the motor right now has about 3000 miles on it. its broken in and never been beat on. i did take it to the dyno with a very conservative tune (11* of timing up top, and 11-1 afr) letting off at 7k rpm at 17-18lbs of boost it made 355 whp and 273 ftlbs of torque. if i would have gone to 8500 who knows what it would have made.it was a 3rd gear pull. most people do 4th gear pulls because it usually shows more power. thats what the dyno guy said. i built this motor to handle 500hp and that is easily attainable with a little more timing, boost and race gas.

buy this and save a couple thousand dollars, and a couple months of time.

asking $4200 plus shipping

hybridynamics equal length manifold. all stainless. excellent quality. collector is beautiful. similar to a full race manifold. t3 flanged and uses a tial 44mm. great shape only 2500 miles on it. no cracks. perfect. $740

the turbo was used on my last fwd sr. i went to rwd. excellent turbo for anyone seeking 500 whp. if some one buys the whole kit i will throw in oil feed and drain fittings and lines. i will trade for a gt2871r,

I'll ask a dumb question, turbo is a T3 or T4 rear?

t3 rear. if the motor gets sold than the intake manifold will go. you will be the first one to know.
