My compression checked out to 195 - 200 across the board. I'm at 110,xxx miles and I believe it's time for a rebuild. However, I would like to go with a higher compression piston. Obviously, I would have to get an EMS. If I were to just rebuild the motor with higher compression pistons, what price am I looking at? I've never rebuilt an S2000 motor, I'm used to b-series. Also, if there are any recommendations on what I should focus on while rebuilding the motor, please share.

Thanks in advance!

 

Don't rebuild it until it's really broken

 

What makes you think you need a rebuild? 195-200 across the board should be fine, depending on a bunch of factors, but within 5psi is extremely encouraging. I'd definitely dyno it, preferably with a few other similar S2k's, before going to the trouble/expense of a rebuild you probably don't need.

Personally, if my '01 were in need of a rebuild, I'd either rebuild it with a 2.2 crank and rods, or just throw a good used 2.2 in there.

 

I think it really depends on your goals. If the engine is working and power is still healthy why mess with it?

However, if you already have your heart set on a build for higher compression etc etc, then it's better to start with an engine that's not broken.

 

???

I feel exactly the opposite. If the engine is healthy and all you're planning on is bumping compression, I wouldn't bother. If it's due for a rebuild, then go ahead and mod things in the process.

If the engine is literally "broken" (i.e., cracked block), then of course you wouldn't rebuild it! But the idea that a worn engine due for a rebuild is "broken" and not a good place to start is kind of a funny notion, IMO...

 

I dyno'd it back in October. The vehicle only put out 187 whp and 135 tq. I have Berk headers, Megan Exhaust and AEM v2 intake. I feel that's a tad bit low

I'm just going to start setting money aside for this rebuild of mine. If I wanted an OEM rebuild, any ideas as to what that might run me? I eventually want to go ITB's.

 

If you are in SoCal I have a recommended builder that did mine. All stock rebuild will probly run you about $4000-$6000.

 

^ Oh god, that's ridiculously expensive. I'm going to go high compression pistons with springs, valves and retainers tuned on an AEM EMS and I don't plan on spending more than $3,500. I'm located in Tampa, Florida. Thanks for the input though!

 

6000 will buy you a honda crate longblock. I'd take that over a rebuild anyday for that price.

 

Were there any other cars dyno'd that day to benchmark with? Depending on what your mods are proven to be worth, 187rwhp might not be terribly out of whack if the dyno is "low" vs. others (most of which are optimistic).

Anyway, I think I'd just look for a good used 2.2 from a low-miles wreck (preferably rear-end first into a tree/guardrail/ditch/whatever).
