Customer feedback?
Do a search on YT for airbox silencer removal or deck plate mod. Drop a K&N filter in, tune it, tweek the timing,and upgrade the exhaust for starters. There isnt much IMO to do without tearing the engine apart and building it up into a beast. Those are the least expensive things I know to do for starters. hope I helped. Blue

Well there's not much you can do at all...the 3.0 is a gutless, but reliable engine.
I recommend you drive it until the engine won't go no more and then replace it with a 3.4 or a supra swap.
Good luck.

3.0 mods that are easiest:
2.5" mandrel bent exhaust w/ turbo muffler
clean out your throttle body
change all oils in car to synthetic
do the intake mods (drill holes in airbox) and silencer removal
give it a general tune-up, change fluids
increase ignition timing by 10* (listen for pinging, run premium gas)
That's pretty much it... use ECT if you have an auto, too. Oh, if you want you can also do the cold start fuel injector mod thingy and possibly bump up timing a bit more with no pinging...

If you increase you ignition timing by 10 degrees that should put you around 20 BTDC. That seems a little on the high side to me.
Check out this thread for intake on a 2nd gen. I added a couple pics at the bottom.

I'm going to put a 5.0 in and forever forget the 3.slow
(my 4runner tows a diesel air compressor, so it needs a little more grunt, and a little more brake to be completely confident pulling a trailer)
on the trail though the 3.0 is fine, 5.0 would be more fun tough
