I'm for sure doing an engine swap but I'm torn between the B16a2 (SiR-2) and the B18c (GSR). will the b18c be a direct bolt in swap into a 95 civic dx?

 

they're both direct swaps. i say whatever you get for cheaper. if they're both the same price, get the gs-r (unless it has mad miles or something). they both have the same redline, similar hp ratings, the head is basically the same. the only difference is that the b18 has 200cc more displacement.

 

but what's the difference between the 92-95 gsr motors and the 92-00 gsr motors?
