100lbs. to minimum weight. .041" to .050, must add 200 lbs to minimum weight. Max. .030” overbore. No rotary, or 16 valve engines. Camshaft must be stock lift and duration. No long duration camshafts allowed. No adjustable cam sprockets or offset keyways allowed. Pistons and head must be matched; no mixing of pistons and head to add compression. No grinding on rods or rod caps. Engine must not exceed 190psi per cylinder
(NO EXCEPTIONS).
Handicap for 12-valve engines: All cars with 3 valves per cylinder must run a weight of 0.1 lb. per
CC. EG (1500 CC must run a 150 lb. weight). All penalty weight will be located between front and rear firewalls
and be securely fastened to the car.


Is there anything i can do to the EFI to make more power

You can look at a custom dyno tune but I don't really know how much you would gain on a stock 2.3

I do not see anything about s/cing it lol

What is that

I'm assuming he means supercharging. There isn't anything in there about forced induction but if the rules are that strict I'm sure it isn't allowed.

Ya No Turbos/Ram Air or supercharging

What about gear ratios? If you go to a lower ratio that would help things out.

If you are still running an engine driven fan for the rad, swapping to an electric one will save you a few horsepower.

Im running 3.08 now in 2nd and 6400rpm going into the corner I have tryed 3.55 and 2nd gear and was hitting 6500rpm just past 1/2 way down the straight away...i would love to find a set of 3.27

No i have always run an electric fan

Is there an mods to the EFI that i can do.....bigger injectors,fuel rail,throttle body,fuel pressure reg...etc...are there any parts from a 5.0l that will fit on it
