Vlt Running Gear Into R33

[MZTRBO]

Hi Guys,

Just need some info for my mate so here it goes;

The car is a r33 gtst and it now has an rb30/25 sitting in the engine bay. Some questions we have is in regards to the vlt auto gearbox.

1. As you may be aware this gearbox is not electronically controlled like the r33 auto's. So my question is will the car have any difficulties running a fully built auto gearbox from a vl. The car was previously manual so no auto ecu in the car.

I figured it wouldn't be a problem but better to ask.

2. Are vl turbo and r33gtst auto flywheels the same?

3. How do we go about getting a proper signal to the speedo? I believe the vlt box is mech driven speedo and the 33 elect delivered? Any ideas?

4. What tailshaft combo could we use to bolt it all together? Atm the entire man tailshaft is in there and its to long by a few inches. Will putting a front shaft of an auto work?

Can anyone forsee any other issues with using a setup like this?

Cheers and thanks in advance,

Daniel

1. if the gearbox doesn't need any electrical input then it will just do it's mechanical thing and not batt an eyelid. If the auto is fully built then it shouldn't need anything like ignition cut on changes etc.

2. nfi

3. nfi

4. get the front half cut short and then the whole lot rebalanced.

why would you want to do that anyway?? whats wrong with an r33 box... and why wouldnt you run a manual??

fo speed o signal use a vdo signal generator.

do what i do .... drop both shafts to a specialist and usually 70-80 bucks later its all sorted.

Few reasons actually;

1. Bought all running gear out of 10sec VL so it came with the package.

2. R33 gtst auto is electronically controlled and doesnt let you utilize an replacement ecu as they do not control electronic gearbox's. So this leaves you with only piggy backs ecu's.

3. Taking the manual out and replacing with an auto as I mentioned earlier its for a drag setup. If you need me to explain the benefits of an auto over a manual in a drag application let me know.

VDO thing sounds good, but how does it work exactly seeing that the box end of things is mech and not electronic..

The tail shaft thing sounds good, but I guess we will experiment first with the man/auto stuff as we already have some, somewhere.

1. That's what I thought. In mentioning the ignition cut I thought the same thing and also realise that the tailshaft will be completely solid aswell, whereas a normal auto tailshaft also has some kind of gas/compression thing on the back shaft to reduce the force aswell. We'll see how the box goes I guess.
