The downside is you lose a v8.
i Don’t think I’ve ever heard someone considering doing this change before.
Would you not just supercharge the v8?
All of the above
Latest M4 engine makes more sense in a E46 M3 surely....
ok guys I should have explained better its in a e92 m3 race car and the s55 seems the way forward to make more power I cant super charge as the cars has to have bmw parts and have come out of the factory in some format
Well, that makes more sense i guess! I think physically fitting shouldnt be an issue, an e92 335i runs an n55 which is what the s55 is based on, so i imagine subframe, mounts, gearbox etc will be straight forward. Not sure on the in’s and out’s of the ecu and fuel system etc, but i think with some work, time and money its do-able.
If you are allowed to tune the engine there is a successful Dutch motorsport team that build their own S65 engines. They do a few options from 500bhp to 600bhp all in beautiful naturally aspirated form. A google search will find them.
