so if they left the crank bolt out? its the tuner that makes up for it?

i think the more important aspect is not who BUILT - it but who TUNED it...
IMO - poor tuning breaks B20's, not high RPM/side-load/RS ratio etc...
both guys who handled my tuning knew what to do, so make sure if you do a B20VTEC - get it tuned by a experienced tuner...
BTW - instead of re-inventing the wheel, guys have a read of this thread before asking simple questions:
what's the max rpm a stock b20 is good for and what would be needed to take it to around 8,500?
is b20b8 or b20z better in terms of both performance and compatibility?
also, on a built and camed (sk2 pro1) b16a2, would be worthwhile replacing the b16 bottom and ctr pistons with a stock b20 bottom (maybe with high comp pistons)? or is that just asking for dramas by using a built head on a stock bottom? and i assume i can't reuse b16ctr pistons in a b20??

We have taken stock B20 rods to 8800rpm's. We capped the rev limit to 8600rpms though. I would run a set of H or I beams forged Rod for piece of mind.
Just use a b20b8...
And yes, it would be worthwhile to change your b16a bottom end to 2.0l. A stock B20 bottom end spec will run fine with your headwork. Check out phamburgers b20vtec. Thats running a V1 spec bottom end with headwork. Its making over 130kw with less than 10:1 compression
CTR psiton wont fit the b20, different bore size (81 compared to 84mm)
