depends on what you think "extreme" is. With the hasport mount kit you have to remove your stock tranny mount (grind the welds) and use hasports. And you have to get a slim radiator fan. or cut your stock one. But thats it.
Also, I've read that you can use your stock radiator(not recommended because you need a higher capacity radiator for the bigger engine) as long as you change the fan and use an ultra thin one. I'm doing this swap and I'm planning on using a Fluidyne radiator with an ultra thin fan.
or you could save some $$$ and get a stock vtec del sol radiator. And "a real racer doesnt need a/c or p/s"?? lol.. are we on fast and the furious?...
