Ok, i'm throwing together an H23Vtec motor. I'm not wanting to spend a whole lot of money. I thowing around some ideas on what to do. First, cleam up the block check the bearings see if they are ok and just throw an H22 head on there. Second, check the bearings to see if they are ok, tear down the block and get some H22 OS pistons to put in there. Third, check bearings, find 2 H22 B pistons cause my H23 block as AABB on the piston bore and i already have 4 A pistons from my H22A4 block. My question on that would be can a machine shop make it so all the bores are the same to support the A piston. I'm just scared cause of the lining on the walls. But please anyone and everyone chime in.

 

Anyone?????

 

If you wanted to have the bores rehoned to the same size, you would prob. need to have it honed over to accept the .25 OS pistons. A machine shop could do this.

Second, I do not recommend reusing bearings. They are fairly cheap to replace while the motor's out, and can destroy the entire motor if they go out.

Third, while you are on a budget, I would STRONGLY advise that you at least have the bottom end balanced at the machine shop.

 

Thanks, another question would you use H22A4 piston with the floating wrist pin or use the H22A1 pressed in wrist pin?

 

If I had the choice, I would go with the floating wrist pin rod.

The only difference in the two is you can easily take apart a rod/piston that's joined w/ a floating wrist pin; a pressed-fit wrist pin must be pressed out at a machine shop.
