Hi, I tried to search but could not find any definite answers. Does anyone know if KA24de pistons from a D22 Nissan frontier will fit in a 240sx KA24de without any modifications. I want to lower is compression ratio to 9.2:1 for my KA-T build @ 8-10 psi by using quality cast OEM spec pistons. I don't know if anyone has tried this setup before. I read online that D22 KA24de has a lower (9.2:1) CR which is the ideal CR for my setup. I know many people use the stock 9.5:1 CR when doing a low boost KA-T. Also, I know people would advise using forge 9.0:1 pistons but I have my reasons for wanting to use cast 9.2:1 piston, less thermal expansion, faster spool, drivability, ect. I know my idea may not make sense to some and I apologize in advance for asking a question which seems dumb or has been discussed before. I am currently I'm the process of purchasing the items for my build and deciding on the pistons is holding me up.

I found some threads stating that 99-01 altima also has 9.2:1 CR. Does anyone know if the altima or D22 pistons will work in 240sx KA-T.
