Might have just found myself a 2.0l silvertop (34k on the clock!!) to put in my rs1800. I just have a couple quick questions about it, firstly, my rs1800 has a superchipped ecu (CULT) will this be ok with the 2.0 engine? secondly, i have an ashley 4-2-1 and full exhaust system which is pretty new on the 1.8, will this fit straight onto the 2.0l? thanks alot, danny.
