I was playing with the idea of making a 2.4L H22A1 (H23A1 Crank and 89mm sleeves)... and then turbocharging the project... All the added displacement will give the turbo a nice kick in the *** , but I was wondering what kind of problems I might be looking at... Before I start dumping money into this project... I tried searching, but didn't really find anything...

Thanks.

 

89mm is too small to start out at. if anything happens to the cylinder wall it had better be fixable in that 1mm or you will be resleeving.

too close IMHO.

 

Stick with the stock stroke and stay with a 88mm bore maximum.

keep the bore small ,87.5 or 88mm , but u can run a h23 crank its worth the tq for the heavy car

 

If you go 89 bore use darton m.i.d kit sleeves, they give you iron cylinder walls.
