Ok, so I am still working on actually buying my 80, but I do have a question.
A little history, I sold my '88 3.0 4runner. The mods to the drive train were geared toward rockcrawling. You know the usual SAS, dual cases, 35's, arbs, trail armor including an arb front bumper, OBA and on and on. Anyway, back to the 3.slow. I put the downey headers, high flow cat and magnaflow muffler on it. I left the ignition alone, everyone told me stock was as good as it gets. I put a k&n in the stock airbox. Those mods made a signifigant difference in power. The final piece was a 3mm overbored throttle body. That also made a nice seat of the pants difference. It would run 70 mph over Donner Summit outrunning my buddies 4.0 jeeps that were built along the same lines. I haven't seen anyone do anything with the throttle body on the fzj80. Has someone done it and I didn't find it or has it been tried and no benefit was noticed? I just see guys going toward porting and polishing the heads and everyone saying that headers would/don't do anything. I'm not looking at doing anything right away or if ever. My question is, has anyone approached this as a system, ie. throttle body, headers, etc? It just amazes me that every manufacturer's intake/exhaust can be improved (including other Toyotas), except for land cruisers. How did they make it so that there is no improvement to be made. Discuss.
