HOW TO GET MORE POWER FROM MY S14..??

[Cov]

Hope this is the right forum for this, going to rebuild my M3 evo engine, I know it has different cams and one or two other differances from the normal M3 but i was wondering if any one knows what i can do to bring the power up around 250 or 270bhp without puttin on a turbo or superchrager on it, any help would be get thanks.

Spend lots and lots of money......

Wilder cams,
2.5 rebuild
Alpha N with a carbon airbox

Do all these things and you should be looking at around 260-270bhp - and a bill for around 5-6k

2.5 rebuild
High compression pistions
284 cams
Head ported and gas flowed
All parts blue printed
Carbon fibre airbox
alpha N

why are you ruling out a turbo or supercharger conversion? you cant beat the kick up the arse you get when 15+psi of boost kicks in

Turbo is the way to go , monster torque increase, around 40% minimum increase.

S14 internals are very well specced and will stand some FI abuse , conatct "Rowdy Burns" on the forum, hes done an S14 Turbo install with Wasted spark( EDIS), good results too.

Thanks for the help lads, where do i go for these parts tho...? and sorry for soundin stupid but whats the alpha N...?And has anyone done this on this site and how much did it cost. willing to spend about 5-6000 euro.

On the turbo kits, I've had evo's and subaru's and just don't like the power delivery, no offence to anyone i think the work that the turbo guys do to make them work is brillant and fair play, but just not for me.

You can get most parts from there.
Alpha N is engine managment system. Are you doing the work yourself

[Cov]

Oh right sorry Ya well my mate works in an engine shop so he will be porting and polishing the head but he's a jap mad man and hasn't done much with BM's. Was hoping to get it built and then bring it some where to get set up....!! Good idea or not..??

You can tune alpha N from a laptop inside the car by urself

[Cov]

Oh right, will have to do a bit more research on this first, thanks a million for you help.

[maxfield]

if you want alot of info about it try www.s14.net

[Cov]

OH Super, again thanks very much.

This is true, but in reality its just not possible to tune the maps while trying to hold 5k RPM in fourth!

You really need a peggable rolling road to tune properly.

100% agreed !

you can map on the road quite sucessfully, however the pegged road speed offered on the dyno makes reaching specific load sites a lot easier, and you can tune for best power.

saves some extrapolation, although personally I use datalogs to dial in the last 5% of the map.

Bottom line for anyone cosidering this route, decide what you want from it before lashing the cash, and take lots of advice too.
