Hi All,

I was just wondering what the highest whp and boost pressure people have ran on H22 without sleeving the block, on the Stock FRM liners?

Ive a sleeved block on one of my setups but the other has Stock FRM Liners, with Mahle Gold Series pistons, Eagle Rods etc, so wondering what power people are running.

Also how long have they lasted?

Cheers

the stock frm sleeves are at least as strong as the other stock sleeves honda has used, they use frm because it is stronger.

If you have the standard mahle h22 pistons they use a standard pin, so I wouldnt push it much past 600 or so with out upgrading the wrist pins.

 

Ah cool, cheers JD.

Im only planning on making 550 engine power on that setup so around 480whp. That will be stock H22A or A2 Block with uprated Pistons / Rods / Bolts etc.

My other setup is running around 505whp, but running Darton Sleeves also on H22A.

Cheers
Jay
