EJ22t Swap

IdenityCrisis · 04-30-2004, 01:37 AM

i have a 2000 rs, i plan on swaping in a 91 ej22t short block and keeping my ej25 heads.

1. wht will the compression ratio be? wht will i have to do to get it around 9:1?

2. anyissues using the 25 heads on the 22 block? such as coolant passages or anything like that? or sensor holes that i willl or wont have?

3. is it possible to bore the 22 out to a 25?i want to hone the cylinders anyway and put forged pistons in, but if i can i'd like to bore it out to get more displacement and higher cr with different pistons.

any info on this kind of swap will be helpul, thanks - IC
