standard sr internals are good for 400-450hp with proper maintence and proper mapping,the weakest part of the sr engine is the standard head gasket,,put a steel gasket on them and they will hold upto 450hp,,i had a standard engine before with totally stock bottom end with just a steel head gasket running 2 bar boost and no issues,i would not but in a rb20 over a sr20 but maybe thats just me
