Thanks. Ill update when news arrives.

 

This sucks...I was hoping they would hold out on me.

I'm wondering if I can squeeze another "season" w/the stockers.

 

I think if you keep it in the low 500whp range and a good tune, you should be ok.

I pretty much immediately saw issues once I was in the low/mid 600 range.

 

Laskey quoted me yesterday for a complete head build, containing Supertech nitride SS valves, Supertech springs and Ti retainers, Supertech valve seats, full head disassembly, hot tank, deck, valve guide check, 3 angle valve job, and assembly and shipping back for $900 total, that is a untouchablre deal!!!!

 

Well that sucks, I was pushing for 600-700 this summer.

Of course it will stay in the 400 range 95% of it's life..just as it did last summer.

Only turning it up a handful of times over the summer, or the 1-2 track days.

Still, this has me concerned.

 

Yeah, Mike is great to deal with and I highly recommend going with him and his work.

 

In my car, I can't speak for anyone else, I do all sorts of driving. Street driving, cruising, highway pulls, tons of drag racing, two step, etc.

My car would still run a decent number under boost, but I would notice a drastic decrease in idle quality. Eventually, after adjusting the valves like 10 times, 2 of the valves broke. In the mean time, this put a lot of wear on the seats too.

Good thing about boost.......haha. My old Subaru motor had 60%+ leakdown in all cylinders past the valves, and it still ran 10's. Actually, that motor, which was beat, was the only time I got into the 10's with that car.

What's strange is, I ALWAYS used stock valves back in the day in my 9 second FWD car, and never had issue. For some reason though, with the S2000, it just doesn't work. That said, with a drag car you often accept certain things that you wouldn't in a car you drive on the street a lot since you don't see much variable in the driving condition and type of driving.

 

I tried the 2 step one time while I was setting it up. Didn't "sound" right, so I haven't been back to trying it since...winter came to quick

I spoke to a well known tuner about this yesterday, he said in some instances, some people who are making big power on stock components could be running ultra conservative timing which is causing their EGT's to be higher than normal causing the valves to warp.

I'm still going ahead w/my plans..see how it pans out.

I'll save the headwork until next winter.

 

Just hope the worse doesn't happen and wipe out your entire motor. I got VERY lucky when my valves broke. VERY.

Typically it's catastrophic when that happens.

You also want to make sure that your VTEC is locked in while on the two step. This can cause some serious issues too if overlooked.

 

Yeah my valve failed exhaust side cylinder #3 at drag races shortly after using an ignition cut limiter with no retard. I was low 600 whp.
