I'm in the middle of having a shop do a motor swap for me. An H23a with a full exhaust (sans header), port-polish work on the head, and a forged crank.

He knows that I want this engine for boost, and has done evereything accordingly for that. I am moving to Florida and will be doing the rest of the work there. For obvious reasons the mechanic wants to do as much work as I can afford. I'm about at the end of my funds, but I still have 2 options left.

I can either: Resleeve (get rid of the FRM), and go with a thicker turbo head gasket to drop my compression (done the right way, with longer headstuds).

or

Replace my OEM clutch and flywheel with about 100,000 miles on them. Still in working order.

Which should be done first/is easiest to do now? If I go with the clutch/flywheel, which would handle modest boost (no more than .5 bar) the best?

 

i say youre in a lose/lose situation
its a good idea to resleeve the block but that clutch you have on there is not going to last long if at all with boost

 

You will need to resleeve to go w/ forged pistons. Without resleeving, you will be limited to no more than 10psi to be safe.

If you are going to boost regardless, then replace the clutch first. The stock clutch WILL give out when you start boosting.

 

Can't you get a stronger clutch instead of OEM?

I'm not a fan of using thicker head gaskets. If you want to lower your compression, do it right and get the appropriate pistons. Considering that sleeving is one of your options, I would assume that you are getting new pistons for this option, anyway, right? No point in sleeving if you aren't getting forged pistons.

 

1) Resleeve with forged pistons/rods.
2) By the time you get everything built and assembled, then broken in...you 'should' have saved up enough for a nice clutch.

Stock H cranks are already forged.
