my b18 intake manifold

[12mod]

hi guys just chasing some info i have a b18c5 jap spec engine in my eg when we lifted the motor out to respray the car i found a dirty big crack in the manifold i have a spare b18c2 vtir manifold am i going to lose much power if i run it instead.

any thought would be much appreciated.

thanks james

How did the crack happen? Your b18c2 wont suck in as much air as the b18c5 because of a smaller port. Not a GREAT difference but good enough

im not sure it looks like its been there for a while though so maybe last time i had the engine out should i track down another type r manifold

[lsvtec]

unless u can get the manifold welded or else just get another type r manifold

Even if u wanted to run the b18c2 intake manifold it won't fit your b18c5 head
