it's a common build... B16 > B18 head. Talk to Steve Leitner about building a good engine for his needs.

how about the obvious ?
b16 block with a b18c1 head?

imported_gatherer

why though .... there is no benifit there (in my opinion) to get the b18c1 head you'll probably have to buy the complete engine at which time it's just better to drop that in because there is no replacement for displacement

well im talking about b16 head on a b18c block.. i not sure why anyone would switch it around

ryuujin

well one reason I could think of is is possibly getting better flow once the B18C head is ported

apparently it seems to be a good combo with the turbo... I know b18a is LS not GSR but its the same idea...not sure of the reasoning behind it why they chose the b16 head instead of the GSR head... but it seems to work well with the turbo...must make less compression... but n/a you would want the opposite... I guess it depends on what he has planned for it...
