ok for the record i'm still new to these stuff but will a 2jz-gte performance rods and pistons, etc.. fit into the sc300 blocks? b/c i'm planning to built my stock sc300 engine for turbo and finding performance internals for the sc300 is pretty difficult..

 

yes they will fit, same block man. the onyl thing that will not fit is the exhaust cam from a GTE b/c the GE has a dist gear on there.

 

GE and GTE rods are identical. GTE pistons are very similar to GE and have only a slight cup volume difference.
If your power goals are not over ~500 HP, stock pistons and rods with a thicker headgasket and new rings should do the trick for you.
