B18a Or B Im

[cbrnascar0329]

i'm building my crx with a b18a and was wondering if there was any significant advantage of use a b18b intake manifold. i've heard somewhere that if flows better than the a's manifold. i can get the manifold from the guy who's building my motor for practicaly nothing. he's willing to swap evenly because he has no use for the manifold.. thanks.....

i think the only dif. is the throttle body a is 58mm b is 60mm

they both suck. get a skunk2. its cheap, and flows much better. 8hp dyno at the wheels on a stock motor.
built- boosted, it only gets better
