Currently stroking out a B18, kicking around the idea of ITB's on it. Would I not have enough space to do an effective setup, or would I not see the gains to make it worth the time?

^^^ He might know a thing or two about it

 

I have a friend with a 90 CRX with a b16 in it and slapped some ITB's on it an it definitely fit and made good power.

 

there is a crx on this months issue of super street, if you look closely it has twm itbs on it. looks really nice.

 

Cool, I haven't done too much research on the geometry/math of choosing correct runner lengths and stuff yet. But, correct me if I'm wrong, short runner length is good for throttle response whereas long runners are better for top end horsepower? Also, how expensive are mass produced setups compared to a DIY? Not sure what size throttle body to use either, stroking the B18 out to 2.26L via Crower kit.

It's the other way around.

 

Ah ok, which makes better torque?

 

longer runners, hence the better throttle response.

 

Is it necessary to run velocity stacks, or are they just an option? Also is there any type of filtration setup on ITB's?

 

All of the brand name ones that I have seen are already shaped like velocity stacks. They do help air flow and I would recommend having them if yours doesn't. Also most I have seen aren't filtered but I do think some sort of filters are available form various filter manufacturers, you'd just have to look into it.

 

Thanks for all the help.
