I'm about to rebuild the head from a 1988 bmw 730i.
(The oil rail bolt loosened, causing the oil feed to fail at the front of the cam, this quickly removed the cam lobes on number 1 and
2 inlets).What modifications are worth doing to this type of engine.
A piper cam will add 12 bhp .... which in a 1600kg car would be unnoticeable.
(Where the 85bhp-128bhp modification in my 680kg citroen axgt was very noticeable).
Would i be better off with a standard camshaft and concentrate on fuel injection modifications, 6 > 2 custom manifold and maybe a performance front box (tuned expansion box).
The car is mint .... i've put 2 stonechips on the front over the 8000 miles since i've bought it. The single owner before me put 3 on the front. (Over 108k!!)
I intend to keep this as my main car for another 3-4 years before moving on .... i nearly bought a 68k v8 car until i noticed how loose the doors were, then how worn the pedal rubbers were, seat belt webbings worn,etc ..... clocked methinks. (And the bonnet had been resprayed over rust dots ... very strange). All other v8's i've looked at are a pile of s**te ... the only good one i've seen was over 7k. (I'd rather spend 7k on a porsche 944).
What say you guys.
