Jesse’s S13 first came to me as a 700 dollar shell with an auto tranny and a completely shot KA24. Within a week, Jesse had sourced a RB25 and tranny and had 2 wiring harnesses ready to be wired up.
When it came to the mounts, Jesse had sourced a shop that was closing in San Jose off of Bird Avenue. After review, the mounts looked to be a Ruckus Racing knockoff, and the shop had left us with doubt, but they worked like a charm
Within 3 hours, we had the stock KA out and the RB25 mounted and ready to rock and roll.
After dropping the motor in, next was getting the car to run as it was missing the turbos, exhausts, maf and intake pipes.
Deciding to go the budget route, Jesse had me weld a wastegate opening into his manifold, and we opted to use a Ebay adapter flange to go from Garrett flange to the T3 flange. After test mounting the turbo, a Pro Street AN oil return line was installed.
Running a T3 62-1 with a .84 a/r and Stage V hotside, along with a Pro Street downpipe and Pro Street Stage III Intercooler Kit using a Spearco 2-216 core, Jesse’s RB25 put down 325 SAE corrected wheel horsepower at 14 psi on my Dynojet.
My time tuning Jesse’s car was limited as his stock side feed injectors just couldn’t keep up with the turbo. After 6000 rpm, the injector duty cycles began to creep above 85% which was well above the Apexi Power FC warning threshold.
