Build log
- 2011Bought as a tired KA24DE automatic coupe with 174k miles for $2,300. Ran, barely.
- 20125-speed swap over a long weekend. First proper drive on Angeles Crest.
- 2013SR20DET blacktop clip landed from Osaka; swapped in a two-car garage over one winter.
- 2015Z32 brake conversion and 5-lug hubs. Finally stops like it goes.
- 2017Full respray in factory KH3 Super Black — back to the original paint code on purpose.
- 2019GT2871R, 550cc injectors, Nistune. 264whp and the first dyno sheet worth framing.
- 2022Fortune Auto 500s and fresh bushings, aligned for street. It rides better than stock now.
- 2024Garrett G25-660, ID740s, Walbro 255, Haltech Elite 1500 — 312whp on an E30 mix.
- 2026Fifteen years in. Not for sale.

Ask the mechanic
“I want 350whp” →
It already knows the chassis, engine, and what’s installed.
