wow thats very impressive! ya the main thing holding me back now is my fuel pump, running out of juice around 6200. I plan on replacing that pretty soon. So was the rs-t a 420a or a 4g63? Ive seen the 420as do some impressive times however I would imagion the 4g63nts to be a better motor. I hate people that tell me I can't put boost to my motor! Sure these internals were never meant for boost however the 9:1 pistons were designed with the exact same material properties as the 7.8:1 pistons, only difference is higher compression. therefore just run a bit lower boost thus lowering the internal compression ratio.
