A lightweight flywheel does wonders on a NA engine..

My '2f legal' front running full built N/A 1.8 engine produces 180rwhp on a dyno dynamics dyno.

The 180rwhp peak is not the number to look for its the huge gain in torque over std thats impressive :twisted:

How many hours is it rated for though? From what I heard most of Gary Stewart engines are about 30 hours in "2f legal" form.

Mine has similar characteristics. It makes 140rwkw (187rwhp) at 7500, but at 4800rpm its already making 105rwkw (140rwhp), and the torque curve is very broad.

speaking of mods,
my na8 is very basic. 4-2-1 extractors, 2.5' exhaust, mania cold air.
also have a straight through pipe for track so remove the rear muffler. more for hecktic noise, bro!

the car has suspension mods, good tyres and pads and roll cage.

very basic mods and my best at wakefeild is a 1.12.8.
my first time at wakie in the mx5 was hand timed doing a mid 1.16. mind u it had standard intake and exhaust at that time.

while its quick for what it is, the other mx5 challenge cars run from 1.08 to 1.10 with rebuilt motors etc.
im at this point where i'll get an ecu to fine tune the most of the power it makes. hopefully then with better track conditions i'll be looking at low 12s high 11s

so as others have said, do basics, drive the sh*t out of it and fine tune the suspension and tyres and driving style!

Thanks Guys, I wont be getting anything untill summer uni holidays when ive saved up and have a life. Also technically a cant drive the car by myself untill I get green P's in febuary next yr which is why im going to be doing more fixing/upgrading than driving (I know it should be the other way around)

Engine
Cams
Exhaust
Intake (possible mania?)

Chassis
Coilovers(probaly yellowspeed)
Brakes(already ordered HPS pads and braided brake lines - done)

Tires
Federal 595's Semis

Misc
Race seats/harness/Roll Bar

Any other suggestions on any other mods?

Wozzah's cams.

My exhaust... :mrgreen:

Works engineering intake (awesome price, ask mania for it or PM me)

Get in a car with yellowspeeds first.

Get whatever dished wheel, quick release, pedal covers, seat mounts etc that make the car just perfect driving position for you.

Why can't you drive the car on red P plates?

The yellowspeeds are ok if your on a small budget, if your not there is better available.

Don't go the Federal semis, you would be better on some Dunlop Starspecs (Z1) that are classed as S specs with a rating of 300.

I didnt have the car when I took the test, which was in an auto, so I cant drive a manual by myself untill I get my green p's, when the RTA thinks that I am now magically able to drive a manual.
