I've decided to rebuild my H22 w/ a possible spun bearing 'caus I can't find an SH short block for less than $2200

I had the head redone already w/ new SS Valves new guides and seals. New autotensioner and cometec head gasket .

when rebuilding my bottom end what are my best options to mate up with my current head (I'm not changing cams or any part of the valve train it's already done)

This car has 40,000 and has already had the bolts from the flywheel back into the clutch and ruin 1 crank at 15,000 miles so everyhting should be fairly new.

Should I also replace the clutch while the engine is out even though the oem one has hardly any mileage done.

I will NOT be drag racing this car any more but it may see an occasional Auto-X

 

It depends. If you wanna raise the compression then your gonna have to sleeve with new pistons and rods. but if u wanna keep the same compression and about the same power you can just rebuild with oem parts.

 

I don't need to sleeve for type s pistons though do I? i get a little bumo in compression there are there any other types of pistons I can use to pick up some gains.....I don't want to sleeve but I would like to make it faster and stronger then it was before.

 

for type s pistons you dont have to resleeve. But for forged piston you would have to resleeve (ie. JE, CP)

 

or you can pick up some 11.25:1 wiseco pistons designed for frm blocks. they are very strong, very light and reasonably priced as well.

where can i pick a set of these up at? the only ones I could find are the low-comp ones.

And as for the rebuild: replace everything back to stock. The only thing that I can see wrong is if you spun a main bearing. If it was a rod, then screw it; it'll be replaced. Otherwise, you'll have to have the crank turned and get the right size mains. I'd also recommend some general machine work while in there:
-shotpeen the rods
-balance the bottom end, or at least the pistons and rods
-maybe micropolish the crank
And there's no need to replace the clutch yet, if it hasn't been worn much.

 

wiseco came out with them abotu 4 months ago
i beleive that the best places to get them tha ti know of are http://www.raceeng.com ans http://www.polydyn.com
polydyn charged about $20 more but they coat all their pistons.

 

If you have a spun bearing the rebuild may be more involved. If it was a rod bearing you may just need to refinish the crank and replace the rod. If it was a main bearing the block may need work. You just have to take it apart and see what the extent of the damage is. Some info on type S pistons:

Good luck and keep us posted!
