Proposed NZ Classic Japanese race series

[KiwiStaz]

There appears to be an interesting race series being proposed in NZ that might suit the starion. I see that dirtygalant has already found it on toyspeed.org.nz

Rules

2.All cars must be at least 20 years old and this will be a rolling 20 years i.e. 2009 – cars must be pre 1989 and manufactured in Japan.

29.Cars cannot compete within the series if they do not comply with the rules.
30.Cars will be scrutineered to ensure eligibility.
31.The quickest lap time for Pukekohe Park Raceway will be 1 min 7 seconds. Cars that lap quicker than this time may be excluded from the series.

Not sure I like the rolling age rule (no 2) as your car could become obsolete as a new one becomes available (eg next year 300zx TT, supra's with 1jz come available). Saying that a starion could be creatively built to the rules - my interpretation of rules 5,10 and 15 would allow you to build a widebody replica that could run wider tyres and rules 18 to 21 sound like they might allow twin camming...

How would you interpret the rules and build a car for this series?
(don't worry I am miles off being able to afford to copy your ideas)

Hmm im interested now, but only if we can put twincam head down to a FREE engine mod. Don't see why not as im still using a starion block haha

[JD_Stazza_Brendan]

doesnt mention diff gears.

responsive 300hp MPI starion (GSR-V would be the go) on the edge of weight limit with 4.6 diff gears.

Alternate engines for rallying here in Oz state you must keep the same number of camshafts & valves as OEM. Not sure how a 16 valve DOHC MPI stroked Staz would pass under those NZ rules.
The concept sounds great, but more rules are needed to avoid the 'grey' areas of interpretation.

The twin cam head would fall under the fact its a later model engine and also the hybrid rule, ie using two different head engine combos to make the engine.

I would go the dash engine to meet the rules as they came standard on the gsrv, it would give you the similar power potential as the twin cam head.

The idea of allow replicas suck though, as theres nothing stopping you from building a modern chassis with a classic body.
