on my stock B18a1 intake manifold theres 2 wholes ( one for the tps, the other for the fast idle).......i noticed on the skunk2 or blox intake manifold theres only one hole (which is for the tps).......do those not use a fast idle or something?

Also......on my intake manifold theres a EGR valve......but on the skunk2 an blox theres no flange for it....i just want to understand this all.

 

anyone?

 

On the B18b the manifold only have one hole because the fast idle is mounted under the thottler body. But the B18a the fast idle is mount with the manifold that why you only see one hole because that manifold his built for B18b. You could still use it with your B18a throttle body but you will not have a fast idle or you could just find a B18b throttle body to use so you could still have a fast idle. If it don't make sense holla back to me I will try to clear it up for you.

 

you pretty much cleared it up for me.....but i have one more question..

whats up with the EGR valve and flange on my stock B18a1 manifold?....i dont see a flange on those other manifolds (skunk2, blox, etc...)

how would i hook that up without the EGR
