What is the build spec on the engine, a 731 head with 264 duration cam? Eta exhaust manifold, M20B20 or B25 inlet manifold? Which AFM and trottle body? What injectors?

[Ant]

525E lower CR bottom end

885 head

stock cam and 2-5 inlet mani iirc

Neil, DO NOT fit the E36 M3 injectors !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

nor do you require an FSE

your AFR plot is 11.5:1 @ the top end, there is plenty of fulling in the system as is for the spec of youyr engine dude

cheers ant, what do u suggest buddy

[cliffybabe]

eta im also running a big bore 2.5 throttle body with alpina 6 branch in addition to the other bits ant has mentioned

Put any more umph into that cabbie and you will blow the chrome off!! Seriously,to make a noticable difference will cost big ££,settle for what you have,or stick an M50/52 in

na i dont want to loose the m20 lump got to much on it now

Im thinking about a remap and going over to supe ron too

[cliffybabe]

ok i have found my eninge build thread BArry recomend a 272/272 and Ant recormended a 273/273 CAT cam

What benifit would i see running a new cam?? What brand is better I have seen evolve are selling the CAT cam for £220 too

Thanks for ur input guys im lost when it comes to bits like this

[reggid]

i would run cc273/273 or dr284/272 with the later probably retaining a tad more lowend

[cliffybabe]

so with the cams Cat and Shrink is it just branding

[ShakeyC]

The cat and shrick cams with same the numbers are not actually the same profile, they measure and calculate lift and duration in different ways so a cat 272 and shrick 272 can be very different profiles.
