Ok, my USDM SR20 is blown and I'm going to replace it with either a JDM or European 10:1 DE. I can just use my USDM sr20 ECU with it right? Does it make a difference that the compression ratio is higher? Or do I have to get it reprogrammed?

It will be fine.

The JDM ECU does not have any provisions for the US emissions controls. If Colorado has emissions testing, you will be SOL.

Unfortunately not. There is no place on the JDM motor for the EGR system, and your intake manifold will not bolt to the JDM head.

I think that the EVAP system will work if there is a vacuum port available on the JDM intake manifold.

JDM motors are more easily adapted to the 91-93 B13s because they are both high port, and the intake manifolds are interchangable.

Have you searched on the www.sr20forum.com ?
