I could understand why he would ask a question.....the springs and retainers are probably much stiffer and strong in the E46 vrs. the E36 which means higher revs. I did it to my 240sx thats got the whole sr swap and can rev to 9000 safley, by putting stiffer springs, well i doubled them actually and did a few other things, but the concept is the same. Maybe thats why B) atleast thats what I picked up, but hey I've been wrong a whole butthole load so eh....

Yeah, I just mainly wanted the springs and retainers for a higher rev limit. I had the chance to get a e46 head at a discount so I was only wondering how compatible the parts were.

you can get euro springs and stuff, first you would need a soild lifter conversion that runs about 1600$USD, the only downside to solid lifters, is that they need to be adjusted every 20k miles.

Yep, the self adjustable valves don't need inspection once in a while. You need other pistons as well to getting a higher rev engine.

I was not clear in my answer.... Only the eurospec M3 engine has solid lifters indeed. He needs to be sure if he wants the extra maintenance or not.

If your talking about the euro spec s54 engine. there is no difference between the euro spec and the us spec. they are actually the same engine. however the e36 s52 engine, us spec is detuned a lot compaired to the euro spec. The s54 vavles do have to be adjusted about every inspection 1 service. About the valve springs. I don't know but it doesn't seem like it's worth trouble. But hey it's your car.
