There is a limited auto selection that can been used for auto conversions in GTR's, the easiest conversion is using the auto from a Stagea 4WD but you wont get 5-6 gears.

From there upwards in power capacity there are stronger auto transmissions however expect even less gears.

The biggest cost is taking a auto and adapting it to take the GTR transfer case and bolt straight on, not a cheap exercise.

Your better off getting a built Stagea 4WD auto as most of it just bolts straight up, reducing the amount of engineering involved to make it work.

i assume your talking about the M35 transmission? how much power would that be able to handle roughly

WC34 (WGNC34 as Kiwirs4t pointed out), they ran the 2.5L straight 6, bolts straight to the rear of a RB26....obviously you will need the RS Four 4wd transmission to remain 4WD.

The M35 models got a V6 and it wont bolt up from my understanding.

I wouldn't think the M35 trans bolts up - he would be talking about the WGNC34 trans.

Frankly I would give the R32 a miss and look for a small auto performance car.

That is trick but the box alone is $15k-$30k plus the padel air shift unit

c34 4wd stadea box would be the most cost effective way to do it

Then there is a company in sydney that make a T350-T400 auto adaptor kit to suit the GTR but these are really a race application setup

I don't have an objection to an auto GTR (I know some people do) but its more that you will need to go to a lot of trouble and expense to get an auto that will hold a lot of power. Also when you go to sell it after getting bored with being out-dragged at the lights by Honda Civics (unless you stall it up and do a full noise launch which can get a bit tiresome/embarrassing) you won't get your money back.

Yeah I agree, the stagea box will be fine unless you are putting out some serious numbers, it will be by far the easiest option to fit and wire up.

And I reckon, if you want a GTR and you need an auto, go for it! It's your damn car, do what you like

I would think the stag box would be plenty strong enough for a stock 32 GTR for cruising duties

Obviously if he wanted to race the car it would need something stronger like the TH350-400 or even 700 might be enough once built

Well the OP did say 400-500Hp, the stag box built should be good to a reliable 450 (abused) from what ive read about them.

If he wants more power than that, then open the cheque book and look at the T400 option for reliability.

It really does come down to his need due to his disability and his power goal.....everyone should have the right to do what they want to their car.

If he is concerned about reliability, dont constantly rape the car racing everyone.......lots of people out there running lots of power on stock manuals but they dont clutch dump and bang the gear shifts, avoiding the need to buy a OS88.

The biggest issue you'll face is that the auto is controlled by the ecu. You could run the 26 off the 25 ecu with either an SAFC to put 2 afm signals into 1 or a selin dual maf translator kit. There is some jiggery pokery to get the tps and iac to work correctly on the 26 using the 25 computer.

The up side is that series 1 auto stageas go for next to nothing for one that has a ratty body.

You could even set the auto up on an aftermarket controller, but I'm uncertain on cost.

      Duncan's V37.......race car?

      By MBS206 · Posted

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
