Fik it. I've got a spare if you need to salvage any parts.

If your idea of mods includes an aftermarket catalyst, then count my car in. Otherwise, all stock M20B25, 3.73LSD, 15x7 wheels w/ 225/50s, B-Sports and IE Stg3 springs. With the tank topped to the neck I've returned 365-370 miles (mostly highway) on the trip meter which is around 25mpg. Maybe a tad better if I grandma the throttle.

No wheels or driveshaft.....0mpg :(

[dandingo]

Mine's mostly stock with a Mark D chip and suspension. I just did an entire tune up and got 28.5 mpg from L.A. to Palm Springs and back this last weekend, between 70 and 85 mph. I also had the a/c on about 50% of the time. It was about 90% freeway and 10% city. I get about 18 in the city and 20 if I drive like a 90 year old.

[nando]

yeah, they only hit a max of 40% dc though. 21-24# would perfectly suit my current power level but I got a good deal and they were barely used - and there's lots of room for future growth. :)

[cheades]

Nando, you are running 42# injectors???

S50
24# injectors
3.5" maf
JimC chip
3.23 lsd
10-13mpg on the track, 25-28 freeway

[nando]

Sweet. So there is hope for my turbo stroker project.

your friend is probably getting poor mileage from that fuel-only setup, the timing is way retarded and it has to run super rich to compensate.

[einstein57]

Turbo M20B28
Holset HX35
Volk Adapter
MSnS w/ Waste Spark
60# injectors
3.73 rear end

I am getting about 20 mpg mixed with lots of romping on it and about 25 freeway.

Stock ETA
Dinan Chip (came with car, I wouldn't pay money for that piece of shit)
2.93 LSD

I have a rubbing caliper on one side that is dropping mpg by about 2-3 mpg that I need to fix. I used to get 25 city and 29 freeway.
