Since I'm back in town, I got the chance to finish up this car that I started working on back in 2007. Car had a ton of issues that needed to be sorted out from leaky injector seals to a clogged cat. Anyhow, finally got his tune done.

Motor is running strong considering it's got 147k miles on the stock bottom end.

I'm looking to do the same. What exhaust are you running and what kind of cat? I'm assuming this is tuned with K-pro?

It's not a swapped car. It's a 2005 RSX type-s. I forget the exhaust the guy has, but it's a reatively quiet one. Yes, tuned with K-pro.

Gees look at the tq and power curve, its a beast for a RSX and would be wild in a lighter chassis.

There's another guy I'm in the process of tuning that has an even bigger beast of a motor. Only 10hp less than this motor, but on 3.5psi. He'll break 300 when we get him boosting 6psi to redline. It's a K24 motor in an ep3, so stay tuned for that one. Hopefully sometime later this summer I'll have some final results for that motor.

bad-ass numbers... Does the 05 RSX-S come with a k20z1? and 05 that already has 147k? That fking insane.......

What kinda rh and exhaust is he running?
Whats the a/f at? 11.5-11.8 in boost at full throttle?

Actually, my mistake, it's a 2002.

JRRH, fujistubo power getter.

The a/f doesn't need to be that rich on an RSX-s with only 9lb of boost.
