itr manifold...worth it?
 

im considering swaping in a itr intake mani/ TB/Injectors on my otherwise stock b18b. anyone here have this done?
any noticable diff in performance/milage?

ITR manifold is different than the b18b, it won't fit.

i thought so to, but a few people i spoke with were insistant that it would.
so my only options for intake mini is after market?

you could make the ITR IM fit but it would involve drilling new holes and some aluminium welding (not worth it IMO).
So only options are aftermarket. I am using the AEBS typhoon IM along with a 64mm t/b and fakedata intake manifold gasket (totally worth it as well). I was impressed with how well the AEBS IM performed. Its not the prettiest peice and i've even seen some that needed the runners cleaned up a bit b/c there was excess casting. But for the price it can't be beat.
Or of course you could always go an buy the $1200 US AIR Endyn intake manifold.

fawk that, i could get a super charger for a few hundred more
lol

don't waste your time with a supercharger. Not on a B18B. If you want to boost go turbo. Superchargers aren't as efficient on a 4 cylinder as they are on a V8. It takes power to make power with a S/C.

I have the itr manifold for sale....I am supercharging....
