I've been searching for a Jatco RE5RO1A for ages, and have never been able to find one for sale.

Are they that rare?

There are plenty of the 4 speed RE4RO1A models around...

Currently, I have a Jatco 4N71B (VL 4 speed auto) matched to my RB25det, and I really want to upgrade to the 5 speed auto.

If anyone knows of a place I might be able to ask about getting one, could you please let me know. Thanks.

I think you'll find it's the same as V35, M35 Stagea, and late model Patrols. The latter two obviously have a transfer case.

Happy to be proven wrong, but I'm fairly sure that's it.

hi ive been told that the 5 speed auto came in the non turbo 32s and as the trans housingis the same size as the 4 speed the internals are smaller(read weaker) so that the whole lot would fit in

in theory, could I buy this, rebuild it with stronger parts, and fit it to my RB25det?

Aftermarket ECU to run it?

. so you you want to pull a recon trans apart so you can fit stronger parts?your keen with deep pockets that for sure, i know info is limited but you might want to investigate this 5 speed AT some more. . .you might find your car is pulling the same revs in 5th as it would with the 4 speed auto,aftermarket ecu to run it? MIGHT be something out there

Not so interested in the revs in the last gears. More interested in the extra pull from the early gears.

I found the gear ratios in comparison to the 4 speed, once, a while ago. Cant find them again. But it was something like this:

1 - 3.857 - 2.785

2 - 2.140 - 1.545

3 - 1.384 - 1.000

4 - 1.000 - 0.694

5 - 0.694

    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies. 
    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
