I was just thinking that we could save my fingers from doing the walking.

Anyone have a tip on where the best price on a good set of underdrive pullies might be? Ones that come in colors would be cool, but any of them can be painted I guess.

The motor they are for is a '90 J-spec turbo...

Thanks,

 

I'll try to save you some money instead. Underdrive pulleys are a waste on a road car. Your alternator is gutless enough without you slowing it down and lowering its output further. You should only underdrive your water pump if cavitation is a problem, which it is not on a street car. Unless you spend a lot of time at constant high rpm (i.e. race car), you will not notice any difference (you'll be lucky to see 1-2hp on a dyno), but you may cause cooling and charging problems.

 

Thanks for saving me the money. Dual belt pullies it is...
