might sound like a daft question but does the 323 end up with more power than a standard 325 with the manifold mod? also how can you tell the diffrence between the manifolds?
With just the manifold, you will get very close to 325i power, but still not quite there.
The full twin pipe exhaust might help too.
Apologies if this constitutes a thread hijack - although Mark might be about to ask this, anyway ...
With the manifold and chip/remap (which?), what kind of power increase might be expected, please?
I'd expect 200-205bhp with both.
The manifold by itself would make about 185bhp, and the remap alone would give similar power figures.
Thanks for that. So ... 200bhp should be fairly easy and relatively inexpensive to attain.
Wait a minute ... I can't believe I'm even considering modifying this car!
For one thing, it's supposed to be a short-term, stopgap kind of thing. For another, it's automatic. And finally, it's fairly special even in standard form and it seems a shame to mess with it.
Regardless, I've had several items of interest in my eBay watch list for days, now!
For a non turbo petrol car, the 323i and 328i's have some of the largest gains on them, purely by unrestricting them.
keeping an eye on this thread, i have the same car.. what other mods are reccommended?
328 cats and backbox (or fancy 328 spec aftermarket) will help, as the 323 came with a 320 type single pipe exhaust.
The 325 and 328 both had twin pipes all the way back, and the 325 one will fit fine, but there is a lambda hole in the 325 exhaust that would need to be blanked off.
