Currently I can get about 21 mpg on a good week. The car is very sluggish though. My best 1/4 has been 16.4 with some mods. The car has about 250k on it now. I've had it since 216ish. Its had a recent timing belt change and I've changed all the fluids. What should I do to make it back to factory specs? And where is that DIY of changin the plugs on the 2jz? I cant find it anywhere.

21mpg is very good! I wouldnt mess with that!

How do you drive your SC? I accelerate pretty gradually, rarely blasting off the line, and I get 25-26 mpg. 97' SC300 68k miles.

I average 85mph on the local highways and not very hard acceleration at stop lights.. 21ish mpg with the 1jzgte. If i go 65-70 on the highway, i can get better.

what exactly is involved in a tune up

changing plugs is not very easy to do. you will need to take out the upper plenum to
get access to nbrs 3, 4 and 5 plugs.

clean your throttle body while your at it since thatll come off anyway.

plugs, wires, rotor/cap, timing belt, w. pump, serpentine belt, and i think thats it? thats all the stuff i changed when i did my tune up. and tightened up the throttle cable a bit.

edit: i just notice you drive a 400, im guessing its easier to change plugs on it and not sure exactly where the throttle body is.

rotor/cap= is that the disrtibuter?

what is the cost around to get a tune-up... myself or mechanic?

RaynArt

roughly 340? about in parts. could be a little more since i remember buying misc parts/access. i didn't really need but since i was buying car parts anyway labor was $60 and a pizza since i knew the guys.

Thanks for jackin my thread

Anyways does anyone have the writeup?

Also, does anyone know if I can use the same caps, rotors, wires, and plugs on a 1jz?

remember you'll need 2 dist.caps on a sc4 , and get a good set of wires.I've heard through some threads here that it is quite common to get a bad wire in the set exp. with the cheaper plug wires.
