All that has to be done is the custom mounts nad IC adn exhaust .

Try and get a Celica AllTrac Alt bracket though . So you don't have to cut the big notch in the frame .

You can make well over 400RWHP on a stock block . 525 RWHP has been made on a stock block .

With rods and stuff it will be much more reliable though .

If you haev any questions hit me up with a PM . BTW I was at my freinds house when I posted last I was FCDrifter .
