M52 conversion m3 exhaust issue

[slim91]

Hi everyone I'm in need of a little help in currently trying to fit m3 manifolds to my m52 and am having serious trouble and was wonder if anyone who has does this before may be able to display me a few photo please thanks slim

Modified M3 manifolds for use on an S50 E30 (should also bolt on to an M52, maybe a bit mismatched for a standard M52 )These are done by BTB, some people do it diy style by altering number 6 to clear the bulkhead and then ensuring the collectors/ down pipes clear the steering linkage!

Thanks for the help they look pretty tasty what's the quote for some of these?

You don't want to know the price trust me, At least £1300 with your current manifolds in exchange.

Standard ones will fit with a bit of modification to the lower pipe, but no good if you want to go E36 or E46 steering rack. You also need to bash the bulkhead in at the corner of the transmission tunnel near to where the steering column bearing is on the bulkhead.

There are some pics of the ones I ran on my old build thread, they may be around page 30 but I'm not sure

Not worth the aggro really

Just get some M52 ones ready to go from DanThe

Some manifold pics from this page onwards.

Another tip, if you do continue with the S50 manifold, fit the coont when the engine is out of the car.

Thanks man has helped abit cheers I'm think I'm still going to battle it out for abit as have made abit of recent progress also have a e36 rack fitted what is the difference in rack I can't remember ? I'm just stuck on the first 3 now did you have to modifie your to get it past the subframe will up load pics if ever completed aha

The E36 rack causes the primary pipes to need to run closer to the block.

There's no massive gains to be had by it, especially by the time you have hacked it about trying to get it to fit.

Save the time and money and flog it on ebay and buy some manifolds of DanThe and be done with it.

I've bought a predator system with their manifolds, made 13bhp over my last system (m52 manifolds to e30 325i system + scorpion back box).

[ross_jsy]
