Absolutely nothing BAMF. I think what the guys are hinting at is why by the old ls version when you can get your hands on the type-r (just an assumption).

I like the old integra's but I wouldn't touch that sucker at 2500. Myabe 750, yank the engine and tranny and drop an old DOHC 6G72, their certainly appears to be enough room in the engine bay to accomidate the swap.
