one for the brainiaks
was thinking today about using a 3.5 litre nissan 350z engine and gearbox in a seven style vehicle. now some of the 350z's have that trip-tronic
(flappy padel) gearbox and i woundered whether you could incorporate that into the seven as well?
what would be involved in taking it out of the nissan and into the seven? what parts would be needed etc

ECU and masses of wiring I would think...

I would expect that the paddles would just be connected to micro switches so you could easily make something to attach to your steering column and
maybe just use the actual paddles and switches from the donor car. You wouldn't need to use the whole steering column enclosure. The paddles
would need a pivot and end stops and the switches would just need to be held in the correct position on a plate of some sort.
The wiring wouldn't be too scary I don't think as you should be able to just lift it straight out of the donor. It's not as if you
need to build a loom from scratch yourself.
Sounds interesting - keep us posted!

I wouldn't even bother thinking about it to be honest. The wiring and ECUs required to make it work will make it pointless. Assuming they will
work in anything other than the parent car. Things like this in new cars are nice, but not really transferable to a 7.

(Sorry to barge in - again).
I disagree...I think it might be easier than you think. Depends on how the gearbox works at the minute.
Alot of the bike engined boys use a button/paddle to switch a solenoid to nab the next gear, while the ECU kills the spark temporarily...so you get a
flat shift.
Alot of aftermarket ECUs are coming out with flat shift options already built in (The latest Emerald does).
The difficulty will be how the gearbox currently works...is it just a fairly normal sequential, or is it something really flashy that needs oodles of
electronics to work properly?

^^ What he said, but beware, a lot of japanese cars have intelligent transmission computers which learn the way you drive to optimise gear shifts.
Clever shit, and way beyond me!

surely it would work if i took the entire loom from the donor along with the engine & box etc and then just dropped it into a chassis?

Indeed - these days an engine needs to be able happily talk to another ECU or two on the car before it will probably even wake up. I guess you could
always add a simulator of some sort, but you would need to know the CANBUS protocol to even go sniffing... An aftermarket ECU (i.e. Emerald) would be
a necessity as a starting point - but don't expect the gearbox ECU to play ball, so you'd need another one for that..

You'd probably have to take the loom and everything electrical with it, right down to the electric windows...

I think thay have that kind of problem with the S2000 ECU's, but some clever people have worked out how to modify them (I think there is a kit
manufactures in the US that modify S2000 ones)

well , you can get gearbox controllers for the AW series of auto gearboxes which have electronically controlled solenoids , i cant see it being much
different , if theyre electrically actuated , which means youll have to delve into it a bit more serious .
Ive always thought the BMW SMG box behind that six cylinder would make a nice starting point .

Scary stuff, all this electronics! 
My first car was a 103E Pop and the only remotely electronic component was the capacitor in the distributor.
Lots of ideas keeping you busy, Alex!
