is that usdm or jdm. was the del sol even ever available in japan. i tried a google search myself but didnt find what u found

Yes it was, but they were not very common.

Del Sol was the EG CRX, where the CRX that we know of, is the EF CRX.

B16A = JDM 2nd gen
B16A2/B16A3 = USDM (civic SIR/del sol VTEC)
B16A1 = JDM 1st gen

B16s are stout little engines that make 100hp/L. And with the right combination of parts/headwork can make 200whp. Unfortunately since its only a 1.6L its notoriously torqueless, which translates into having to keep the rpms rather high for it to be making any sort of substantial power. Which is alright since it has a 77mm stroke and 81mm bore. So its very high rpm stable. B16s in stock form run out of breath at 7600rpms but with a few mods its not uncommon for these engines to make power up to 9000+ rpms.
Drop the compression a little and add boost b16s can put out very impressive numbers both whp and torque. Even on stock internals they're capable of over 250whp.
