One of my cars has a jg ported p8r head.

I'm just wondering what intake manifold I should put on there...

But then I remembered that I have a couple sets of itb's, so why not try one of those out?

They're for the b16 head though.

Can't I just drill some extra holes and bolt them up?

 

Someone did do a so-so writeup on how to do B16 IM on LS/B20 head...

I think the GSR IM the runners are more closely lined but the bolt pattern more staggered where as the B16 IM was easier to bolt on but the ports didn't match up as well as the GSR IM..

 

Thanks.

The search function doesn't seem to like short strings like
IM and p8r, so I'll keep digging.

Thanks for that.

I had found this thread:

But neither of those threads seems to reference port shapes / angles.

I'll line it up with a spare gasket and take a closer look.

 

The B16 lines up perfectly
