Just wondering ... how difficult will it be to extract say another 30-40WHP out of the e90 325? Is it financially realistic to get that much without any forced induction? With a remap I am informed you can only get no more than 20 ponies, a new air intake will give about 5 ponies max. New plugs ... 1 pony. Thanks!
 
The best is to sell the car and buy higher powered engine car, e.g. 3.0 litre
 
There's not much which you can get out of NA engines. Remap is approximately 7-10% bhp gains at most. If you want 30bhp - 40bhp, it takes a bit of extra effort somewhere else :)

kolamp ... Looks like need to set aside 20-25k ya?

Nahh depends on parts ure going to install...lets say for IHE mod,
Intake cost around few hundred bucks up to 4K;
Header should cost probably from 1K-4K;
exhaust cost around 1K up to sky's the limits LOL
Remap cost around 2K to 3K...

Doesn't meant you have to do it all at the same time....there's no rush, slowly find the parts that suits your pocket and yes like aoch88 said, NA engine will cost u a lot more to churn out more HP compare to FI engine...

A quick solution is to install NOS system which will give u bang for buck...instant HP that cost lesser than I mentioned earlier but ur engine gonna spoilt on long term usage...
 
i would be vary of anybody you says they can get 5hp from just the air filter change.
when i did mine, i bought a pipercross and k&N and after each swap i went to the dyno.
i got 1-2 hp difference. and that can easily be attributed to a million other factors.
biggest burn i got was when i was sold Hiop headers which the seller claimed could do 15bhp.
total rubbish. got the same 1-2hp. and that was 5k for the headers.
if you want to go fast, buy a faster car. modding is hard and expensive for na's, turbos on the other hand....
 
Lokk under d vendor section. Devillian has a supercharge kit 4 a reasonable price, but he is located in sg. I was quite tempted 2 do it on wifes e92 330.
 
Slide ... that is what I suspected ... guess it DOES NOT make financial sense to even try and get a mere 30HP out if the N52. A 335 would be a good solution huh? LOL!

rx8 ... naaaah, wanna keep her in NA form as stated. Then upon reading up more, the N52 is a magnesium block, not that hardy. If can a Rotrex would be a great option to take, their unit has wonderful results. But then ... loadsa money need to be spent.

stroker kit!!! google it!

not worth the investment vs hp. especially when your current engine is still running strong. better you save up towards another car with the hp that you want. unless you have ooodles of cash to burn :)

Mr Singh, you are correct. Not worth the investment. Maybe the 135 for a fun weekend car ... looking at something like that. But I have to say a Boxster is also most tempting.

lol....i'm not singh la, i dont have pisang raja, only pisang putera. :D

yes, fun cars for the weekend. my friend has a 135i, it's nuts. very suited for the times when you wear your underwear outside and want to go faster than a speeding bullet. boxster also nice, but attracts too much attention for dd. :)

What colour would you advice me to get those undies in? Better for bikini cut, jock strap style or just the plain old uncle one is best?
