E30 engine conversion

Post Mon Dec 24, 2012 7:23 pm

Hi and Merry Christmas everyone,

I am thinking of purchasing a second E30, however this time I am looking for one to use as a fast road / track day car. I think I have found the base vehicle, however I am unsure of what would be the best engine conversion. I like the idea of a 3.5 litre turbo, as I believe this is a fairly easy conversion, however I don't want to upset the handling. I would prefer a 6 pot as I love the sound of these engines, however a 4 pot would be best for handling. Any suggestions that wouldn't be too taxing to convert?

Thanks.

M52b28 is the way to go. they are light and can get them up to 270Bhp with a few extras on them

Come and buy my S50 powered road legal (just) track car . Turn key sorted car for a lot less than it will cost to build anything decent

A PROPER SORTED RELIABLE M30 turbo conversion will leave you no change out of 5K and then you need a car

Contrary to what is often spouted on the internet, RELIABLE power costs lots of money.

pete, you got any pic's of this fine beast of your's? (keep it clean)

270bhp from a m52b28??? please do tell how you get to that with "a few bolt on goodies"

Am I right in thinking the M52B28 is the E36 328i lump? That sounds tempting.

I would like to build my own car ideally as I can build it to my exact specification, but thanks.

Tell us more ? Which goodies and how much ?

M50 mani with BBTB plus remap 250ish bhp with the cams 270bhp for the 100bhp gain

Post Mon Dec 24, 2012 7:48 pm

Don't forget your K&N air filter, that must be good for about 12hp.

250 bhp with bolt on mods???? I am building a 3.0l m52 with cams, if I hit a GENUINE 250 bhp i will be chuffed. As for 270 bhp, I am not saying its impossible but I am sure Pete's s50 would be cheaper.

EFA.

Where did you get 100 bhp gain anyway?

Post Mon Dec 24, 2012 7:55 pm

Rich, m50 inlet and bbtb with remap would give a real world 230bhp. S50 cams maybe 260bhpu

with M20 flywheel and a good M52? will pull them numbers

Post Mon Dec 24, 2012 8:00 pm

A lightened flywheel will not ad a single bhp or lbft.

Post Mon Dec 24, 2012 8:04 pm

the whole M52 forums over the world but be wrong then i guess lol

Post Mon Dec 24, 2012 8:04 pm

And an m20 clutch is starting to feel the pain at about 220 lbft!!

Post Mon Dec 24, 2012 8:06 pm

Dont believe everything you read on the web!

Post Mon Dec 24, 2012 8:13 pm

i dont mate but im happy now with my setup, with 250 if i can it. the car it fast now as it is... all on top is a bonus

Post Mon Dec 24, 2012 8:16 pm

Dont get me wrong, an M20 flywheel is a must but it wont give any more power.

Post Mon Dec 24, 2012 8:22 pm

i know what you mean but when i did My M20 on it was much more smooth pulling off my duel-mass was fooked anyway. in the newyear going to put it on a rolling raod.

Sanspeed and Bexley Motor Works are both in Bexleyheath.

How much power does a m102 engine make, and what do you need to do to increase it?
