more power for 325i se

[steedymorgan]

any one know the best way to get more power out of a 325i M10 maybe up to 210bhp ish, and can the auto box take that much????

cheers people

You all stock?

would get about 7-10 HP gain from a FULL exaust system...you could chip it,fit racing cams..the list is endless really

depends on how much money your willing to spend

think the cheapest would be bigger throttle b's & exhaust system

though im no pro with the E30's so outhers could probably be a lil more helpfull than lil ol me

The 2.5 is the M20. And to get up to that with out building a 2.7 will be a very pricy affair. A MAF conversion, increase in CR, shrick cam, BBTB and a 6 branch exhaust is probably the way to start. But I think this will only reap 190bhp max although I could stand corrected.

I think Karans 2.7 only just produces 220bhp and he has spent a lot on the build, so I'm afraid you're aiming a bit high.


Oh and yeah the auto box will take it, there is a guy on here with an auto 2.7 can't remember who though.

cheers peps some one on here said something about some chip that only cost Ԛ£55 , i always thought they were much more any one tried one?

i need more low down grunt it's just to slow until you hit 3000rpm lol

Welocme to the world of the M20 engine..lol

i too have the same problem as do most here i think...ive just found out about the chips myself and would get between 4-12HP gain depending on what chip and what outher mods you do to yer Lump...

and yea,there 55 squids..that and an exaust system would give you a noticible difference...

what about a mopified Air-filter? ... PiperCross/K&N etc etc.. you can squeeze a few HP outa them too..

" There's no substitute for cubic inches" someone once said. And they wern't wrong.
2.7 litre build is the way to go, if you want to stick with the M20. That way you get the power you want, along with reliability, and a nice tractable, driver friendly engine.

[steedymorgan]

how much does the 2.7 build cost tho, i just might get me a chip to start off with, thanks for the pointers tho

Forget which thread it was in, but someone mentioned that the MAF conversion was about Ԛ£700. However, an Emerald setup can cost less than that which could well lead to some more power and also the complete loss of the air flow sensor

Tis quite a lot of money, but then finding another 30-40bhp is never going to be cheap

Turbos, you know they're the way!

2.7 build is gonna be round the Ԛ£2k mark if done properly with custom pistons etc..... then ull need extra goodies like cams/exhast/inlet big tb

list goes on really!

then with emerald standalone ecu u shold get 210hp...

mine when last dynod was 213hp and 220lb torque, with old 6 branch, now have a new one, may get car dynod soon actally as its workin great at the moment-would be nice to see 220hp

on the road this equates to porsche boxster humbling speed....0-60 in 6 secs flat and 1/4 in 14.5 with top whack at 144 gps.......

[steedymorgan]

60 in 6 damn thats good, what breaks you running now, cos 325i with abs is not the best and it's got new disc's and pads all round. i think i better start saving lol
cheers all of you for the help

[Karan]

brakes are srf fluid, ferodo 3466 compound front, ds2500 pads rear, ate power discs front, zimmerman drilled discs rear,

it stops very well but the pads are very harsh and i do get through brakes..... but then i do get a bit carried away lol

[twintrack]

N20 is the cheapest way
