Hello all, I will be ordering a shift kit on Monday, and have decided that I want to get a hi stall converter to go with it.

By the time I get my hands on one and get it put in, I am reasonably expecting something in the area of 180 – 190rwkws.

After having looked thru a bit of info about them, I understand that the procedure of picking a torque converter is related to where the engine is making peak torque in the rev range. Not having had my car on the dyno to see exactly where its making its peak torque does make it a little difficult to work out what stall speed I should be looking at for the converter. I notice that the majority of people on here have ones rated 2800 – 3000rpm.

Is it safe to simply pick one off the shelf, even though one rated at 3000rpm might not always be the best real world application? I have read that I should be looking at one that is rated at around 500rpm lower than where peak torque is generated. Using the 3000rpm example, would that be best coupled to an engine that is producing peak torque at 3500rpm?

My intention is once the car is dyno'd and I know where it's doing what, then I can work out what the converter should be rated at. The car is to remain completely drive able – I drive it 400klms a week – so I am obviously not gonna be chasing up something rated at 5500rpm lol.

I am basically looking out for any advice anyone can give about this. I would also like to know about other people's set ups. I have referred a fair bit to the auto power and ¼ times thread that I have found on here, but it mainly refers to numbers, not set up details.

Also, what is the best way of measuring this 'stall' – Flash or True stall? Not planning on having a transbrake, would I be correct that Flash stall would be what I should be asking about?

I appreciate any and all comments or advice anyone has to offer (this is the 1st auto 'performance' car I have owned, so I am like a sponge at the moment – I am soaking everything up lol)

Cheers,

Chris

hey chap

r33 stall convertors are awesome little things.

they still lock up when not under heavy load while the old school chev / ford etc convertors wont.

im running the 2800 / 3000 rpm convertor in my 33 yet the car will happily go up hills at 1600 rpm in drive.

my old chev 3k high stall needed to be doing 2750rpm to move, let alone going up hills.

so in answer to your question contact mike at MV automatics over here in Adelaide and he will organise one for you.

the highest they can go with the stock convertor housing is the 2800 / 3000 rpm that i run, and this will be perfect for you.

if you want to go higher for some reason then you will have to get a smaller convertor 4 cylnder nissan i think, and then that can be modded up higher around the 4000rpm mark but the cost is 2.5 times more then the 2800 convertor.

i hope that makes sence.

Cheers for that mate. Maybe a 3500 is not gonna happen, so a 3000 it prob will be.

My big concern was wether it would need a piss load of revs to just navigate over speed bumps or a slight incline etc.

Have u noticed any difference in fuel economy and what revs it needs to keep a steady 100klms even?

As i mentioned above, the high stall will still lock up and drive from around 1200 rpm and above like a standard convertor, its only when you load it up on the brakes or on a big hill that it will go up to stall speed of 3k etc.

normal driving you wont even know its there.

I highly recomend a 2800 from MV Auto's, and im running over 300 rwkws everyday in my wifes daily shopping bus

Cool. Was seriously worried about drivability of em eh, but i was gonna do it either way.

With regard to putting it in, did u do it yourself? I got a shift on my loungeroom floor that i am gonna put in, but i am thinking a stally is a job for the pros.

If your keen to install the shift kit then the High Stall is simple.

put your car on a hoist or up on stands, then unbolt the trans and drag it out.

un bolt the standard convertor off the engine, and bolt the new one on.

roll your trans on its back undo the pan and install the shift kit then bolt it back together.

with a dozen beers it shouldnt take more then 5 / 6 hours job done.

failing that just get a local trans place to do it for you.

prob around the $300 mark

Stally aint gonna happen for a month or so (fingers crossed i get a new job and get paid out a SH!T load of holiday pay). But i can access to a hoist anytime i want (the stage 2 kit is going on sat), so i am reckon i should give it a shot!

Cheers for all your info dude, much apprecitated!!!

    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
