I recently bought an M20B25 engine with about 165k on it. The plan with this build is to complete an engine overhaul and then find a decent E30 to swap the engine into. I've got it pulled apart and am cleaning and replacing all the bolts, pumps, and brackets. However, I feel I am at a major crossroads with this engine. I was planning on going with a standard M20B25 bottom end with a Bimmerheads Super Sport head with the 274 cam. After reading a ton of material on strokers, I might be interested in a M20B27 bottom end and the M20B25 head. The main BUT in this whole idea is I live in California and must comply with the stringent smog laws. I know the policy is if it looks stock there is no reason they can fail you. Before I make an expensive leap, I need some guidance. So, my questions are as follows:
Has anyone had a 2.7L stroker in California and been able to pass smog?
What do I need to do electronically to make it pass smog?
Will I have to pull everything off every two years to pass smog? (Frowning on this because I had to do this on my E36 M3)
Will the Super Sport head from Bimmerheads and the stroker even pass smog?
What are the differences between the 2.7 block and the 2.5 block and will all of the accessories be the same?
Are things like the oil pan different between the 2.7 and the 2.5?
Are the gaskets the same between these engines?
Does an early model 2.7 fit a later model 2.5 head?
Any advice and leads on posts are appreciated. Thanks in advance.
