i would rather buy a complete rb30engine ender and work with that and put all new parts in,as there fairly cheap also ive seen complete rb30's for $100 in need of rebuild,then get the complete motor ready to bolt in to your car,then when yourve got a spare week off work put the motor in,thats what im doing and it means i can still drive my car around untill the motor is fully complete,also i think u might need the front pipe modified because it might end up to close to the floorpan but thats easy stuff
