go to bimmerworld.com or turnermotorsports.com, lots of cams, and different setups, i think most though are about 245-255 whp on the us spec e36M3. chuck stickley's company would be the one to talk to about building an NA motor.Good luck

300 wheel horse power will be a bit of a challange, but you can change the pullies, get cams, M50 intake manifold, cold air intake,active autowerke software that alows for 100 octane fuel, a track pipe, headers, intake, high performance head, and ofcourse larger injectors. For better power delievery you can change the diff, and get a carbon fiber drive shaft. Wider rear tires would also improve acceleration. All of the engine mods would probably put you in that range.

NA 300 whp is not happening with a US spec M3. The best you can hope for is around 260 whp.

Street drivable NA 300 whp S50B30 US or S52 is not happening. Possible for track use, if you have some mad $$.....

If you don't want to sink too much money, get a SC. Not too much more power, but it will give you power on demand and definitely get you ~370whp if you get a pricier solution....

I agree with Magical Trevor. N/A is so much more than doing a blower. But listen to this word of advice. There are a lot of stoopid people on this forum that will probably tell you that supercharging your car will hurt the engine or run it too hard, but guess what taking the engine completely apart and rebuilding it to factory tolerances is much more of a gamble. Go to

300Whp NA is never ever going to happen for a street able S50 or S52. No way, no how.
The most I have ever see was a fully built S52 race engine and it made 280Hp. (actually 278 and change)

I installed a VF engineering Vortech sc and made 306 RWHp and more torque than a NA engine could ever dream of. The engine has the exact same feel as before, but just seems BIGGER. I have driven TS equipped cars and that is even more pronounced, albet $6K more. The AA stage 2 C38 will make 340Rwhp.

with tall that moneyfor those kits at turner and bimmer world you are better off getting a supercharger, check out activeautowerke.com

I am doubt doubting you guys, so please dont take this wrong. But I think it could be done. Honfa 1.6 and 2.0s have done 320whp on pump, as dailys, with no power adders. It has to be possible.

find me a daily driver honda that has 300+ whp on pump gas. I had a 95 civic hatch with a 2.2liter with 13:5:1 compression on race gas only and it put down 231 whp tuned by the best honda tuner in the united states.

300whp is a far fetch for a bmw all motor. with the money you spend on trying to reach anything close to that you could have put a blower on your car and then you still have more room to grow

I agree with your last statement. I see no purpose in going all motor. Forced induction will always give more power, and in the long run, be cheaper.

It's doable with a BMW motor with the same displacement, just not this one. BMW motors are on average more superior to Honda motors for building them up, for instance, 2.5L s14s have reached the high 200s with street drivability and in the 300s with race gas, but yes, a blower is much cheaper and more reliable.
