EJ20 vs. EJ25 intake manifolds
 

Hi all,

there have been a few people that swapped their WRX EJ20 for a 2.5 USDM bottom end.
As the 2.5 has a slightly larger stroke, does the intake manifold still fit ?

Thx,
Jeffrey

i have fited 2.5 usdm into 95wrx the inlet manifold fits fine the only thing that wasn't a straight swap was the top coolant pipe which needed modifing

it is fine, the blocks are identical in physical size
