Forged Piston Options? All I can find are two Wiseco part numbers
Posted 08 March 2021 - 05:31 PM
K555M92 92.00 Bore 7.2
K555M925 92.50 Bore 7.3
Why is the compression ratio so low on these???? Any preference one over the other? I was trying to find a set of pistons between 8 and 9 to 1.
Anyone suggest any other manufacturers or forged piston options because I cant seem to find anything other than these two Wiseco options?
Thanks for your input in advance.

He can call and ask for Sue Nash. They should have some made already you will just have to purchase rings. same ring set up as oem, just whatever oversize. They are higher compression with 6CC dish Vs oem dish of 15cc

The reason for a low static compression is because it is far less likely to detonate. The boost can be safely raised higher in a general sense.
IMHO - JE makes the best forged piston at a reasonable price, and they are more expensive than Wiseco. They will be lighter and stronger but I think the only option I had was free floater pins. I wanted those anyway, so it wasn't a problem.
Wiseco is a quality piston too and well worth the money. I have them in 3 engines and JE's in one. The Wisecos are probably the best bang for the buck piston.
If you bore it .075 over, then a Toyota 22R at .030 over is the same size and the pin height is the same. So you can order those pistons and they will work fine if you want to bore that baby out.

For 500.00 for a set... I have to say, I was hesitant to go forward and was looking at just chucking the drivetrain and looking at inline 6 or 2.3 Ford. However, I guess since the car I guess has the rare color. I decided to stick with the G54B and just try and add value to the car instead of chopping it up.
