I ran BKR8-EIX iridiums gapped at .025 up to 28psi in my SR. I would get those plugs, wires, and hardwire it and you should be fine. The plugs are about $7 each though.

Holset HY35 for $300 BUCKS ON EBAY. I had a GT2871R and made 365whp at 21psi on a SR20. They are great turbos but they cost $1100 and are not rebuildable. The HY35 has a 9cm2(.48 ar T3) hot side and will spool just as fast as a GT3071R .82ar and make 400whp and 400wtq at 20psi. http://www.ka-t.org/f...

Very impressive for 16lbs. get your fuel pump hardwired and I bet it fixes your leaning out. I had to when I got up to these power levels. If not it's in your tune. When you get the fuel fixed do another pull at 21psi and she will make 400whp and 425 wtq all day long. The HY35 chokes out past 21psi ...

That doesn't seem right...
I'd say that's close in a 2800lb s14. I trapped 115-116mph in a 2570lb s13 sr20 car. It made 360whp with that setup.

I would have to agree with the above post. I would buy a revhard cast mani and a T4 on center before I spent my money on this log. If you aren't going equal length then JGS for T3 and revhard/treadstone for a T4 on center are the way to go IMO.

You should be cuttin 1.7 or better. 20psi is to high(cold or hot?)

300 ft/lb at 3200rpm is awsome. I made 300 at 4200 in my sr20 (GT2871R) ur curve will shift to the right quite a bit witht he holset(HX or HY35?) but it should be about right for the KA powerband. 18-20psi on the Holset will make 400/380tq on the KA-T with a good tune.

235/60/15 MT et Street radials.

With that power level you need to run 13-15psi cold and launch very close to the limiter. With a sub 1.8 60' it will run low 12's for sure. It takes about 350whp to get in the 11's so you are close.
