OK, I'm looking at buying a 70mm throttle body for my b18c1.. I have the skunk2 intake manifold and I was hoping to port match the opening of the skunk2 intake manifold with the throttle body.. i'm pretty sure that will work.. but here's my main question.. BBK makes a 70mm throttle body but they specifically say NON-vtec.. my question is why is it non-vtec I don't see how the throttle body should matter if it's vtec or not.. is it because of sensors that come with the throttle body.. meaning i could just change out those sensors with my factory sensors???

 

i think maybe its for the soch motor, but if it isnt, then just hook up a hose to the map sensor and your good to go. just keep the hose as short as possible

 

Anyone know what else could be the difference in a b16 b18 vtec or non vtec TB?

thanks

 

anyone?? this is mind boggling.. i didn't think there was a difference between a vtec and non-vtec throttle body... someone please fill me in here..

 

just go buy a oem type-r tb & have it bored save your money.

 

well i can get a 70mm for under 300.. boring costs 100 bucks.. so that leaves like 200 bucks.. also i believe i would have to find a 97 type-r throttle body as my car is obd1..

and bumpity bump

70mm is way over killed!
stick with an ITR 62mm unless your making plus 250whp
