Has anyone here carried out a GTS4 auto conversion to GTR.

I am looking at going drag racing this year and am sick of the broken gearboxes that cost an arm an a leg to replace.

1 Is the GTS4 a strong enough box or does anyone know of one that adapts and keeps the 4WD system.

2 Where can i buy the setup IE gearbox loom and ecu

and lastly any problems i might encounter

im keen to know this to as i want an auto in my everyday gtr, its all to hard in peak hour traffic but i dont have it in me to get rid of my gtr so this is the only option,

i would assume the auto has to be "strengthend" but finding and getting someone to do it at the right price will be the hard part,

Sports cars don't have auto transmissions. /rant

If you can't drive a manual in peak hour, then you shouldn't be driving a manual. If Nissan thought the GT-R needed an auto, then I'm sure they would have made it an option.

I would think that if your RB26DETT is trashing transmissions (manual), you will be lucky to make the first 60 feet with a GTS4 auto - it was, after all, only designed to handle a 160kW RB20DET. If you MUST have an auto, I would reckon the box from a Stagea might have the innards to handle a bit of grunt.

Was talking about this the other night with a mate who has a Stag, he was telling me about the manual conversion for stags and from the sounds of that it should be pretty easy to bolt the stag box into a gtr, as mentioned though, need to figure out how to control it.. or get it built and manualised and not worry about ignition cut on shifts :)

I know that Al's Race Glides and MV autos can build Jatco boxes to handle some power....(will run 10's), but not too sure if they have done the Stagea boxes.

Yes, will definitely have to get rid of the electronics and manualise it etc in order for it to handle the huge increase in power.

The GTR box would be stronger than the auto box. So if u are breaking GTR boxes, chances are the auto box wont hold up. You could get someone like MV automatics to strengthen the auto.

Someone on these forums bought the HPI 33 4door with an auto rb26. Think its running 11's. But thats running a strengthened box. Do a search

    • So next year I am looking at upgrading from my VE SS bomadore ute to something more refined.  I wanted to stick with a V8 but not anything German or Australian, either a coupe or a sedan. So if I wanted anything newish that limited my options to either the Lexus RCF which I quite like. But with the price they demand and a kid on the way a 2 door coupe is probably not going to be the best idea. The next best thing would be the ISF but the newest models are 2014 and commanding over 60k and even the older 2008 models in ok condition starting around 35k is kind of bullshit. So I figured if I could not have the noise I could perhaps make do with easy power. Enter the infinity Q50 or Skyline equivalent. The price difference between the 300 and 400hp models seems a bit crazy. Right now there is 300hp Q50 one on carsales from a dealer with 61km for 27k drive away. If I wanted to get a 400hp Red or 400R car the prices seem to start at 43k From my limited research it seems that the only differences are that the 400r/Red Red runs more boost and a more aggressive tune. There are are turbine speed sensors on the turbos. Has 2 pumps for the water to air intercooler. Runs an engine oil cooler. I'm guessing that the exterior trims might look a little more sporty as well. I had a lazy look for upgrades to bridge the gap on z1motorsports They have kits that upgrade the water to air heat exchanger as well as the coolant pump which should give a non Red/400r better intercooling temps than the stock Red/400r. I added an engine oil cooler with a thermostat as well to try and make things as close as possible. Obviously the ECU is going to need a tickle. Having not done much in the way of research they also sell a ECU flashing tool with pre loaded tunes that are supposed to boost the non Red/400R by 100hp which adds 1k USD to the cost. The total cost of the parts @ the current time including shipping and taxes worked out to be $4350 AUD. Personally I would rather get the car tuned on a dyno which would probably add more cost Assuming the worst that you got a workshop to install the new parts I would guess no more than 5 hours would be required in the worst case @ 5 x $150 per hour = $750 So the total cost could be around $5100 So for easy number 5k + 27K = 32k I guess that would leave some change left over to swap out the open diff and fit a LSD Any thoughts?      
    • Right, not sure why I thought it to be a lean spike. It might be fixable with modern card-style hot film MAFs which have some design features to avoid counting reversion flow but I've never tried it myself.
    • I did not realise this, I'll contribute more and earn my stripes and retry later. 
    • I'm only going to hassle you for posting links to images. It's against my policy to click links that could be some nasty payload. Sadly, you need to make 9 more posts before you can just stick the images directly in a post, unless @PranK sees this and bends the rule for you.
    • Hello,new to the group, I bought a R32 from auction recently, wondering if anyone knows the cars history, seems to have the usual go fast bits on it, plan is to do an engine swap- add 2 extra cylinders and 1 extra turbo. https://www.dropbox.com/scl/fi/i4rjmlzubjbwjtguh6f4s/IMG20241011140744.jpg?rlkey=q0lumm251377vknbqktfwrycq&st=7scvwx4e&dl=0 https://www.dropbox.com/scl/fi/ro24qmwzlczzlfsr4y05x/Screenshot_2024-10-10-10-49-23-90_9a2f5bb2149dae94cd1e190effc09b33.jpg?rlkey=oyguh26ttshlf04ccp48odf4v&st=xloae97b&dl=0   New to forums and posting pics, if links don't work, take it easy on me, 42yrs old and I tune carburettors!!
