200bhp+

[bss325i]

200bhp from an M20 will require a capacity increase with all the associated costs.180bhp will cost about £1500

I would say 200bhp is possible without touching the bottom end.

Arguments aside, i got 185bhp and 190lbft from only a £650 manifold and £400 exhaust but to be honest i dont think the exhaust is much of an improvement over a standard one power wise.

seems like a good gain better than the hottuning ones, what power was it pushing out before, or dont you know

171bhp and 172lbft. Completely stock but with less than 50000 miles at the time.

It seems no one wants to give the M20 route a chance anymore, well not many people anyway.

Welcome to 4 pot land!

The ONLY four pot i would consider is an S14.

worth the money then

wish you could get an m42 to sound like a s14 with carbon airbox

Have you heard one up close or just on the 'tube?

[Alex]

just the tube

[bss325i]

just the tube

You have GOT to hear one or better still get a ride or drive in a car with one!

[Alex]

how come they sound sooo good

ITBs hooked up to a hollow carbon air box combined with an 8k rev limit.

I do! The M20 is good enough for what I want to achieve I reckon.

I agree. I think that you could get pretty close with a carefully thought out plan of attack.

I am,of course,quoted out of context,every 10bhp over about 180 will cost about £1000,as proved by my good friend Barry,he spent £1060 or so on his exhaust to obtain 14bhp.Next step is either more capacity or a lumpy cam,problem with lumpy cams is that you destroy the low engine speed drivability,my wife would moan even more!!

Erm... and and and and where's the bloody group hug one when I want it?

[Bob_S]

dan, yeah I saw that, I doubt it's making that atm. Er oh M54 mani's are different to m52's which would explain why I have struggled like a cock to make my exhaust! dohhhhhhh

Alex, it cost me £500 to put an m50 in and change to an e36 rack I did all the work myself mind.

Rav, Burgoil is obviously a pikey and just wants to extract as much cash out of this poor guys pocket as possible.

guy with chromer who doesnt have space to do the conversion sorry I forgot your name, speak to danthe about a conversion

[1an]

a m52 2.8 with the m50 intake manifold will make 220bhp with a remap and a decent exhausty system as proven in 12345kevin' car.

[Simon13]

whats wrong with trusty 2.7 route?!

EXACTLY, I was waiting for you to come on here Simon.

I was about to say that.

210 BHP standard on an Alpina c2 2.7

No messing around involved, will deal with standard 2.5s and most other cars on roads today.

[Jhonno]

More expensive, less economy, slower..

Does give you a fresh engine though..

Of course M20's only for a sport etc

[Simon13]

i've got a good plan for M50's if i ever get around to it, will that be 245 or 265bhp sir?
