3.0lt based, 8.5:1 compression, 500ps (493hp) @ 1.2bar from what I can understand. Japanese generally quote rear wheel power

seems pretty low on power for me, for 1.2 bar of boost

No doubt, but there are a lot of unknown’s, unless someone can read Japanese properly for the correct specs.

Plus we don’t know what dyno was used, an we all know they differ quite a bit.

Update for those interested. Turbo’s are only factory Nissan S15/200sx turbo’s (hence 1.2bar and only 500ps) still runs factory cams, with minimal head work - Port and Polish/port matched.
