S2 RST, engine tune to 200bhp
Hi guys. I'm looking at getting an S2 as an everyday car as kids force me to give the BMW to the wife.
If I find a rather stock one, what do I need to do to the engine to make around 200bhp?
I don't want to go crazy on it as I'd like the transmission to hold for a while.
Does a chip, -31, cam, exhaust and K&N give enough?
Should I rip the head off and send it to a head specialist for a full gasflowed port/polish job?
For suspension I was thinking GroveGarage's damper/spring kit or Koni/Eibach and a set of bushings. Do they need anything else? Does the stock brakes cope with the increased power?
thanks for any advice, and keep in mind, I cannot get a livemap as I'm in Norway

your need a decent intercooler to go with that lot mate , as for the suspension go for the spax spx adjustable kit its very good quality and lasts well add a decent strut brace and a set of polly bushes to that and and it will feel alot better , as for the brakes u will defo have do something with them as the standard ones are shite , depending on ur budget best bet is a set of 2wd cossie brakes up front with drilled and grooved discs and some good quality pads add a full set of braided lines and that will bring her to a stop alot better oh yer and bin the abs
My ex rs turbo was producing 200bhp and 280nm torque.
-AMW Intercooler
-Cosworth sierra turbo
-Kent cams cvh31
-Megasquirt with wasted spark efi conversion
-31 actuator
-Ported head
-Rebuild engine with new parts
-2.5" S/S Exhaust
-10 psi boost
So.. the reliable power is quite expensive though. First i´d drop off the fuckin ke-jet shit. That is useless.

i would say get rid of the cvh block and replace it with a silver top 2.0l zetec. thats wot i did but i have put a hybrid t4 turbo on mine but dont no the bhp got to wait for the running in period to finish til i can get it on a rolling road. your prob looking a 1k mark for the bottom end with fitting. but its sooooooo worth it

mines 200 with chip,-31,possible hybrid turbo,pace ic,ultra light flywheel,solid lifters,panel filter and stainless,boost set at 14 psi.
although ive got a bad oil leak now lol

With Norwegian prices I won't find a bottom end for Ł1k.

mines running tourque of the devil chip pace intercooler stage 2 turbo -31 acturator k and n pannel filter full mongoose exhaust it made 183bhp. was told at a newmans cam and a bigger intercooler should see 200bhp or very close. i will find out in sept as its going back to tourque of the devil once my cam and intercooler are fitted. oh and a ap paddle clutch was fitted as the old 1 shat its self!
The principle behind the ZVH is that you get a great engine with a 16v head and then modify the block to enable the fitting of a 8v head which generally flows less.
To make the most out of any engine you require decent management which has been mapped well
mine had standard engine,chip -31 actuator,slightly larger intercooler,k&n air filter,scorpion exhaust and kent cam and vernier pulley.its the vernier pulley that allows u to squeeze the last few bhp out of it.it was set up by jamsport at 14 psi boost level and made 210 bhp and 226 lb ft torque

ive seen cars make 140@wheels on this spec at that boost,realisticly ur lookin at 170-180bhp at this boost
I agree 170-180bhp is more realistic, when mine had a turbosystems chip, turbosystems cam, turbosystems ported head and uprated intercooler it could only just touch 200bhp
My old engine made 200bhp @ fly and was completey standard, 15psi of boost!
Just had the usual.... Chip, FMIC, Scorpion, K&N.
So long as the engine is in good order its achievable, although very few are!

even on a steel bottom end 14 or 15 psi of boost through a std t3 still wouldnt produce a genuine 200bhp
ive seen many an rst with chip/cooler/exhaust/cam all make in the region of 140-160@wheels,the top end of the scale ones usually have bigger turbo's,newman cam or headwork
as to think that 5-6psi above std boost will make 70 more bhp on std turbo is laughable

well i had it tuned 2 years running and both times thats what it made on the RR mate! I'd post the print out up but that went with the engine when i sold it.
Oh and that was on a standard cam, but the head was ported.
What difernece would a steel bottom end make??

Are you sure about the camshaft thing? My ex rst produced over 200bhp in the dyno with kent cams cvh31 which i think its pretty same as rst standard camshaft.
Now i am asking if i rebuild engine in winter should i use standard EFI camshaft or newmans cam etc.. i now kent cams suck i have now one installed and it last 200km until started making noise.
So has anyone get over 200bhp in dyno with standard cam? With under 17psi
