UK Spec K20 Power?

[FR2000]

I'm looking into fitting a K20 engine into my sportscar. Am i right to think all UK spec are running to 200BHP and its only the JDM spec that are 220BHP? Or does the later model UK spec K20 (K20Z) have 220BHP?

the K20Z4 (used in latest version of UK CTR) has a whole PS more = 201 PS; JDM Integra has 220PS, JDM CTR has 225PS.

Wow, big gains then! I've just wilipedia'd it and they rekon the FD2 which is from the 07 onwards civics have 220BHP?
Any idea who deals in second hand engines/reconditioned engines?

The UK version and the JDM version are as you rightly pointed out different. On the UK civic type R they used the K20 which had 200PS and the JDM K20 as used in the Integra Type R is 220PS standard. They differences are the JDM has a higher compression ratio, hence Integra owners don't really like fitting after market forced induction (Superchargers, Turbos) as they don't tend to have a long life cycle. (the engine needs a lot of work to strengthen it up)
The UK version is more suited to forced induction. I suspect they will be other slight differences in the JDM and UK versions like cams, and definitely Inlet and exhaust manifolds.
Also if you start searching the internet you will find other variants from the US market such as the K20A2 and K20A3

Mugen Euro sell brand new FD2 engines. . .

Remember the higher power variants will be designed for high octane Japanese fuel. Their fuel is very high quality and they can buy higher octane ratings than are available here.
