very hard, not on the street at least, VERY HEAVY wheel spinning with be a big issue, the tyre size, then 2wd vs 4wd...:uh-huh:
never been a big fans of doing such conversion, as they make the car more unbalance. why don't just work on yr sr20det? as the latest speed magazine show a s13 pulling 310rwkw at stock internal. it work out cheaper to mod the engine internal even with those 2.2L kit then do a Rb26 coversion.
