What kind of offset wheels did you use to fit sooo wide rubber under your LJ70?

Not sure what has been done, but I would suggest. Intercooler, boost to about 10-12 psi. more fuel but do not over fuel. bigger mandrel bent exhaust straight through. May I suggest your tyres may be a bit big for the size of the engine without doing some serious engine mod work.

Change your diff ratios to 4.88:1 for starters, these will suit bigger tyres, 3" dump pipe off the turbo into a 2.5" exhaust, get your turbo rebuilt and hi-flowed (is the engine a 2LT or 2LTE?), intercooler (top mount RX7), hi-flow injectors, pump re-time, block the EGR valve...

Check out www.toyotasurf.asn.au for plenty of info on gaining more power.

thanks for all that . its a 2lt and i beleive its already got 4.88 diffs as standard. will fit a boost gauge first to see what pressure i have then will up it to the 11 psi and go from there. link to the surf site looks interesting :lol:
