Small B series intake manifold?
Hello members 
I am busy with an engine swap and by the look of things a stock manifold wont clear my firewall.
At the moment I have a D16 with Y8 head and intake, the intake clears my firewall by 1 inch.
I can not change my engine position really, its a 1986 4wd wagon with the 4wd tranny.
Engine bay space is super tight, so was wondering if there is a cost effective intake manifold out there that has short runners?
I do not have any intake at the moment, just going by photos online it looks like it wont clear the fire wall.

Is the acura integra P72 intake manifold considered as short? Its like an upside down design. Does it flow ok? Looks like it has ''variable runners''
GSR wont fit my head unless I re drill the bolt holes
