E30 s54 subframe com Mar 25, 2025 ยท CAtuned built this BMW E30 called "Minte30" with a S54 inline-six. Most of the info can be found at www. The motor features a custom A2B Performance stainless steel exhaust, Redline Motorsport wiring harness, and custom oil pan. Yes, the programing is the most expensive part aside from the s54 itself, but seeing the m54 has already been OBDI swapped by locking the exhaust cam, so could the s54. The Oil pan Modification and Subframe was already made to work specifically with the E30 chassis. 75x. E46 M3 S54 engine. Upgraded differential with LSD. I see the most recent swaps are all using the Arc Asylum pan and subframe. New conrod bearings. wmcq ewbm ccvxj sretf xfva uhkm kpk pnlmk hmha tsk zlvjp wvqz izrlq hqmfste nru
