I got ahold of a 89 b16a1 head and intake manifold to put on my 96 GSR motor. It will replace the GSr head and IM. Heres the plan, i have all these items laying around in the garage from my old b16 project: ITR intake cam, ITR valve springs (inner and outer) still in the wrapper, 3 GSR cams (one intake and two exhaust). Ill be taking the head apart next week to change the seals and i plan on port and polishing it. PLaying it safe, just smoothing out the castings and kinife-edging the dividers, no heavy port work mostly polishing. The type R springs will go on as well as the cam, I also have a polished intake manifold (b16a1) i will use. The GSr motor was runing really lean hooked to the PR3 so im geting that chipped. Can the block handle 8600 RPM? Thats where i wanna shift with the higher flow head/ITR cam setup. And how much power gains can i expect? I know this is all low budget stuff, but its the only mods i can afford right now..(cause theyre free)

 

P.S. What valve seals do i buy? GSR? LS? Type R? or b16a2 from the honda dealer?

 

What car is this going in?

I would personally stick with the GSR head unless it's in torn condition and needs to have replacement parts beyond the worth of the head. Of course, with the B16 head on the GSR motor, you will yield slightly lower compression with it.

I would definitely use the ITR valve train and such, change the seals and get some head work on it.

The block will handle 8600 RPM easily with that valve train. It's not like an LS motor

As for the shifting points and such, I wouldn't rev it any higher than a factory ITR, and of course with the P/P'ing of the head, I would get a dyno to find out what the max power is for the RPM, and shift at that point, given it's a safe RPM on the motor.

Also with the B16 head, and those cams, you might want to consider a 1 layer headgasket such as cometic, toda or mugen.

This is all in a 89 civic LX. i ran the GSr motor for about two weeks and then noticed a leaking head gasket, and since the head was out im puting on a b16 head. My main reason is the GSR intake manifold. The b16 manifold is better cause its already obd 0 and doesnt cramp up the engine bay like the GSR.

 

yes. that's true. I would go with it then

good luck man.

 

I still dont know which valve stem seals to use.....anyone?
