    Hi all, i have always been in the jap world but after going out in a friends e36 m3 im converted!

    Im just wondering which model is best. By that i mean im looking to buy an e36 coupe which i will use for both road and drift use, ive had a look and im not quite sure which model to buy. I know the 6 cylinder is the best but i want to know which one would be the best to modify [engine tuning] and get the best results, unfortunatley i cant afford an m3 so either 325i,323i or 328i i appreciate your comments

    Thanks James

    325 is popular for a drift shed, cheap, plentiful, and lots of parts.
    If you want to keep something nicer for the road, then go for the 328.

    More power, and although a 193 bhp engine as standard, it has a lot more torque than the 325, and also you have the option of an M50 manifold and a remap to get you to about 230-235-ish bhp.

    A 328 will tend to be in better condition, but 325s are cheap and a lot of car for the money

    hi thanks for the comments, there are not as many decent 325 available so prob be a 328i, i know it has been covered a million times on here but is it true i have to be careful of nikisil on 328i and when you mean inlet manifold is it a complete swap ie unbolting it from the head? what about 323i ? thanks

    yes you need to watch out for Nikasil on both the 3232 and 328 engine.However post 98 engines shouldn't be a problem.
    The manifold swap also works on both the 323 and 328 engine and its the complete intake manifold from an M50 325/525 block that you need for this conversion

    you can tell visually by looking at the engine block (pop the bonnet - walk round the passenger side wing and look towards the bottom/bulkhead side of the engine block)- the below is an example of a nikasil block:



    and a non-nikasil block

    Hi thanks for the advice, im just after a good all rounder reliable but with good power. there are just so many different opinions on tuning and what is the best. I am used to working on cars so ok with spanner twirling. So if im right they all share the same bottom end [different stroke] so can i apply the same mods ie cai m50 inlet 323/328 what about cams can i use us spec m3? and also will m3 exhaust fit and be affective sorry for the barrage of questions just want to get to the bottom of this thanks.

    You can use US M3 cams and and M3 exhaust will also fit

    But if you going to do all this then why not get an M3?Cause all these mods will be expensive...US M3 cams are hard to find and not cheap,An M3 exhaust is also not cheap either

    Ha ha good question and answer is ...... monies! i actually like modding cars and dont intend on doing the mods all at once so i can spread the cost and do it bit by bit.

    Hey man. i just got a e36 aswell and i'm heavily into drifting where abouts are you ?
    i'm lucky enough to have a 328 engine in my 316...
    M50 manifold seems good but what about M3 throttle bodies?? they're pretty cheap! would they be straight swap?

    Alpina527 has done more research into this, the first problem is it will hit the oil filter housing, then after that, the injectors are pointing in the wrong direction, as they want to be aiming at the back of the intake valve.

    I guess some people have already done it, but the fact these easily available mods aren't done points to it turning out to be a failure.
