260DET

Yes, looking at modern cars can be a lesson in where additional bracing can be done on the Z car, MX5 is a good example.

If you are considering a double wishbone rear just make sure that it can be mounted high enough into the body so the car can be lowered without compramising the roll centres. There is not much room up there because the original suspension did not need it.

Yeah they are being done, oh well, maybe for the next project.

Interesting comments and I think that you have nailed the crucial weaknesses in the stock S30 body for race use. Basically the fire wall does not sufficiently connect forward to the front suspension load points. Also the attachment of the front X member which bolts to the rails, the stock four bolt setup allows flex, it's simple to add a couple of brackets forward to bolt to the rails.

A pic of the holed rear would be good, count me dim but trying to visualise the air flow path has got me.

Bloomin heck, go for it but I would have sorted the 2JZ's cooling issues out, some proper bonnet vents would likely do that. LS will be better in some ways though, lighter and better weight distribution if it's back close to the fire wall.

So DCT conversions are being done in the US, I'm just finishing a 6L80E conversion behind a LS3 LOL.

That controller system sounds brilliant, I have a LS3 in my 280ZX race car so a suitable DCT transmission would be needed too.

They have a separate adjustable tensioner, the alternator is non adjustable I believe.

Just wondering if anyone is working on such a project, the electronics would be the challenge I guess.

To check on a belt size and it's run wrap a length of electrical wiring around the pulleys, worked for me.

The most difficult/expensive part is the electrics, an aftermarket ECU is the simplest using a manual transmission. But do you want to go that way?

Good, the US deserves a cheer up.

Some Murrican Dartsun racing action .

This project shows how great the 280ZX can look with some sympathetic attention, a S30 looks dated compared with this embellished S130.
