Jay Perry’s Fully Built 05 STi

The time is here! The time is now to see one of the craziest builds we have yet! This is Jay Perry’s 2005 STihttp://ajwperformanceproductsblog.com in house Engine builder and Tuner of AJW Performance. Jay decided to pull all the stops with this one. Everything has been reworked from last seasons setuphttp://ajwperformanceproductsblog.com for referencehttp://ajwperformanceproductsblog.com Precision 6265http://ajwperformanceproductsblog.com Wiseco pistonshttp://ajwperformanceproductsblog.com stock heads/camshttp://ajwperformanceproductsblog.com stock ecu full weight driver running 504whp. <- Dont believe me?


First 10 Second pass:


At the end of last summerhttp://ajwperformanceproductsblog.com Jay had the car tuned at 535whp (will get the dyno printout). Out cruising one day it was time for a launchhttp://ajwperformanceproductsblog.com spinning tireshttp://ajwperformanceproductsblog.com he heard a big bang. Pull over and get the car towed home and find a forged rod right through the block! Oops. Time for a bullet proof build! We sat down and planned out parts and got them flowing.

This new setup should push Jay’s beast to 6XX+ on our local mustang dyno. Howeverhttp://ajwperformanceproductsblog.com I wont talk about numbers until its broken in and fully tuned.
