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.

thanks for the help man much appreciated ill do some research

Kiwirs4t whys that man i know a lot of people are disappointed to see a auto GTR but I've always wanted to own one so i figure why not :)

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.

      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.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
