H22a
ok h22a supposed to have 205 the a1 and a4 195, jdm engines have higher compression. Type s is 220 with 11:1 h22a is 10.6:1 usdm a1 and a4 are 10:1. If you need any parts for an h22a Ive got them, I recently threw a rod, but everything is fine. go to h22a.org for specs. any h22 should bolt right up in that prelude. the harness and ecu will need changing tho. Good luck with the swap
