Yea, I am in europe. america is paradise for car tuning. Very big market and very low prices and good salary. Low price gas.

400bhp may be asking a bit, with that budget prob 350-370bhp.

looking at some upgraged cams, custom programming with more RPM (prob 8000rpm+ needed), upgraded intake, upgraded exhaust,

the only issue with revving the engine that high is how long is it gunna last. Some ppl upgrade the rod bolts & valvetrain to cope with around 8500. For that sort of money its probably close to what a moderate boost custom supercharger will cost.

I guess when upgrading the engine it has to be in good condition to start with where if its a high mileage engine it probably needs additional work done.

goodluck.
Zsparker is not that far away from U, for memory Dubai not USA

yea i am in dubai

Foler, you dont have to drive abroad to have your M3 tuned. In Poland I am also far from good tuners, that is why, we decided to turbocharge my euro-spec S50B30 by ourselves. I can’t believe that you don’t have any friends or mates who can weld. You only must know how to do it, but on bimmerforums there are a lot of people who would help you for sure. For 10k of $ you are able to have reliable ~0.6bar setup with lower CR MLS headgasket, ARP head studs, fully-prepared cylinder head and good tuning.
