I went thru and cleaned up the ports and opened the TB opening to 69-70mm.

For a B18C head.

Asking 350 shipped

 

Are you selling it because it's not as good as the Type R manifold for N/A?

 

Yes he stated in another post on his All Motor set up he lost 8 ft-lbs throughout his whole entire powerband. This manifold is for a Forced Inducted motor or a very very very highly modified breathing monster of a NA motor. Just my opinion. If I could find a GSR head I would get it as a spare. This manifold makes power on turbo cars though. We tested this mani on a turbo car and made good power gains but a 98 ITR all motor with Crower 63402 cmas made 165whp, uh that's stock power. Once again trying to help Steve here for the forced inducted crowd I'm sure that's why he posted it here.

 

I thought thats what I had.... i guess i thought wrong..

 

Well I guess the manifold is good for FI only then.
