92 4.0 I6

[lt1fire]

I have a 92 land cruiser with the 4.0 I6 engine in it... i've done all the suspension work that i want and have 36" wheel/tire combo. What I really want to do now is put some performance back into that engine with headers/exhaust/CAI/ chip and maybe a performance ignition. Finding these parts though is proving to be extreamly hard... does anyone know where to get these parts?????

any help is greatly appreciated and I am thankful I found these forums

Headers are a waste, stock manifold flows VERY well. 2.5 back or dual 2" with a decent muffler will do a lot. A good tune-up with all oem parts (plugs, wires, rotor, cap, fuel filter, air filter, O2 sensors if you have the dough) will do a good bit too. Then you could desmog it (it wont pass visual though) for a little more pep. Advance the base timing and run higher octane gas for even more advance. Open up the MAF sensor and loosen the gear ONE TOOTH, anymore than that and your mileage will go down.

Other than that there is no bolt on performance parts, you can get cams and other hotrod stuff, but if you do all this you'll be happier than before.
