seeing as this has turned into an engine thread, i'll start a new topic to discuss it.
Hopefully it may get some more input

If so could be a contender, will look into it further.
If anyone else has any ideas post them up.

Dvr1000 where r u located? Will likely be heading down the east coast for a camping trip and will be in Brisbane a few times in the coming months

What is the engine weight of the ma09ert? Wiki shows 112kg, much heavier then the cr13de plus because it's turbo the displacement is multiplied by 1.7 and a restrictor has to be used (size depends on class). It's also only 8 valves and single cam, potentially limiting power/mid range torque depending on cam selection/valve sizing

ma09ert is perfect but also hard to beat an A12 with mazda miata head or well setup turbo

Adelaide is too far for us to work out anything.

I think those comparisons of weight vs the motorcyle motors aren't like for like. The bike motor weights probably includes the gearbox.

Stick with the transverse leaf spring design. You can get them to work and the weight is as low as you can go.

When Holden and Nissan were sharing their vehicles and power trains were there any Holden motors that could be fitted? I'm thinking of the Astra turbo motors. I've seen Geminis with Toyota SGE turbo motors because the NA version was fitted to the Apollos

has to be a car engine with the same number of cylinders from the same manufacturer as the car. so nissan motors or datsun motors that are inline 4cyl.

nissan CR seem to be the lightest i can find with capacity around 1.3ltrs
see here for info
http://datsun1200.com/modules/mediawiki/index.php?title=CR

If i decided to do a PhD in mechanical engineering next year i will attempt to get a project optimising the design of the 1 litre CR engine and try to match power/torque with the larger motors in the series WITHOUT forced induction.
Think koenigsegg's 'free-valve' engine and some of the possibilities for improving bottom end, plus improving top end... plus the usual intake/exhaust tuning and a slight bump in compression ratio, but will limit myself to pump fuel
