yeah they can physically swap in just like a b16 or b17 but I think that the programming differences will be most difficult for him. I think the easiest route would be to find another b18 (either a1 or b1) and throw that **** in there.

 

i agree.. a b20 running a pr4 ecu will be quite lean. the b20 need lots of fuel. I remember jeff saying they do anyways.

 

Youll got any tips on checking to see the condition of the engine mainly the shortblock while its in the car and the cars not running? im gonna head to the junkyard and check out a few tegs.
