That sounds a bit sad, why so uncompetitive? Obviously the better later model cars have good dynamics but the S30 is light and the L engine can be powered up nicely although it gets a bit expensive to have Green Hornet type performance. Are the later chassis/suspension cars that much better or what is it?

Carbotech XP10's are great on the race Z, not hard on rotors either. I could buy pads like Project Mu's locally but instead go to the extra expense of importing the XP10's, good people to deal with too.

Link to AU regs which show variations of designs using self explanatory sketches, a handy design reference http://docs.cams.com.au/Manual/GeneralRequirements/2018 Edition/GQ11-Schedule J-2018-1.pdf As Jon has mentioned this is the time to consider structural aims, from my observations this is often neglected. The priority, tag the cage to the body wherever possible which requires the builder to keep the bars close to the body which some of them don't like because it makes their job harder. In particular keep the A pillar bar snug, the common idea of having a big plate with lots of 'structural' flanged holes spaced away from the pillar gets me, other than looking fancy it's nonsense from a driver visibility and a structural point of view.

Do like the minimumalist look of those flares.

It all looks pretty good, trust me, I'm a body guy lol.

If a car is being used for competition then safety requirements will be dictated by the applicable rules. Rules, just follow the rules......

I've been around here too long lol, years ago I posted details and pics of a basic half cage designed to be light yet providing some protection and chassis rigidity.

Are bearing spacers being used on your front axles that are breaking? There is a thread around somewhere on that topic together with what's available, never heard of breaking problems when using them, primarily they are are used to counter flex which I guess if excessive would lead to breakage.

You've had some good advice here from some patient people who you should thank, about time you followed it and stop assuming eg you said that the engine had fuel so someone reading that would assume that the fuel was at the correct pressure. But apparently you had not checked that so in effect you did not know if the engine had fuel or not. Fault finding requires a methodical step by step approach. Try it.

As a consumer typically with these sorts of devices a detailed and comprehensive list of compatible ECU's is not provided, here I have no idea what the 'MS2 and MS3 family' of ECU's includes. Billet and carbon fiber are all very well, it needs to have a big enough display, really it can't be too big. How big is it?

You want brakes?

This car, only in America

My present thought is to get a complete package from a wrecked car, engine, transmission, shifter, electronics and loom. Have unearthed a local fella who has the software to get it all working and tune it which was my main concern. The option would be to use that package in it's entirety or else use my present good LS3 with the Haltech and loom removed which, together with the Sonnax kitted 6L80, sounds like the best combination. The 6L is lighter than the 4L85E, is more efficient and has engine braking. Have given up on the ZF/Ford trans, to recon one here costs lots of moola plus mating it to the LS is not simple. At this stage of the project plug and play is the word.

Needs more Datsuns.

My LS3 is Haltech managed which blocks that solution unfortunately, the Haltech won't talk with the GM TCU will it. Pity. Powertrain Control Solutions have a stand alone controller for the 6L, anyone use that?
