i just sold Team_dat my 180B, so he can slot an L18, weber and 5 speed into his 120Y coupe.
you can't tell me that an A14 or A15 will be quicker than this - all he needs is a cam and a pipe and it will wipe away any NA A series in the same car.
and considering all the crossmembers interchange, it's gotta be one of the easiest conversions going.
