so i have a D15B7 with no intake manifold an a D15B2 intake manifold ( the one with no fuel rail... ) laying around. I know it will fit but i was wondering however how much power would be lost. considering the TB is like half the size of a B7 intake manifold. minus the injectors etc.

it is going into a 90 civic

thx for any input

 

I am not a pro on the subject but I think that the the loss of 2 extra injectors is probably bigger issue then smaller TB. Since guts of D15B7 are identical of those from D15B2 you can safely assume that you gonna get only 92 HP (just like stock D15B2). Anyone else?

 

well more around the 80's range i bet, count in the miles, any damage the motor may have from the miles and such.

 

motor has about 140k. has been rebuilt however plus new timing belt water pump etc...i would assume also about 92hp

the motor will be runing on the stock civic ecu and harness

 

yes be just like a stock b1 cause the heads are the same in a b7//b1 so roughly 90ish hp

 

what a waste of a b15b7. id sell that pos manifold and get the real one.

 

mpfi!!! :D

 

well power isnt my main concerne...considering its running on a 4 speed tranny.

gonna be my DD gas saver
