Re: cast exhaust manifold v tubular

Re: cast exhaust manifold v tubular

well ive decided im going with the cast manifold. Im sure volvo has put some design into how it flows, and the tubular one i have is modded for the bmw, so maybe its not right some how. but the cast made 7 more bhp on exactly the same engine some years ago... https://bmwrallyparts.co.uk/minipics/bmw...

Re: Lash cap leaving the exhaust valve

is the lack of lift on the valve because you need to have the clearance between cam and tappet when cold? I recently found in my engine a guide to be very sloppy after maybe 300 miles. We think its because i had a sticking injector and its washed oil from the guide. Quat, oh i see, you use the stand...

cast exhaust manifold v tubular

I have a b230a non turbo engine, its never going to do more than 190 bhp imho. Its in a bmw e36. At the moment , the engine has a tubular exhaust manifold, not a kl racing one , but very similar. At one point i had the cast manifold, 50mm down pipes, and the car made 167 bhp at the flywheel. I swapp...

b230 piston options

I have a b230A engine, it needs a rebore really, but here in england there dosnt seem to be any pistons available, no one stocks them anymore. Is there a later piston or one from a completely different engine i could use? I have a feeling there is something as i know of an engine builder here that d...

injector size

I have a b230 with the E type inlet, it has a 300 deg t5 cam in it, upped the compression, im hoping for 160-190 bhp out of it. I had the volvo t5 injectors in it, but they are damaged.
