OK, i have spoken to the Mike at MV automatics, and am seriourly thinking about ordering tomorrow morning an upgrade for my rb20 automatic gearbox, consisting of a 2800rpm high-stall and stage 2 shift kit

i want to know if anyone has gone down this route and can give me a description of how it drives?

Mike said that drivability is alomst normal and the converter still locks on the highway so fuel economy is almost normal too...

apparently their gearbox drives nothing like the traditional V8 high-stall gearboxes...

can anyone give me some insight??

cheers,

Warren

parts have been ordered :D

should take about 1.5 weeks to get them all made and sent out, then i just have to put them in and i'm laughing!

mike thinks that even with the rb25 turbs on rb20 i should be able to get about 4-5psi at that rpm to help me shoot off the line!

13's here i come!!!

(ran a 14.7 @ 98mph with the current setup)

Hi,

i have a R33 4door. I have mikes shift kit, and recently installed a 2800 converter as well.

The shift harshness varies with your right foot, so its not always hard. But boy does it make the tyres work when it does shift....

As for the new converter, its pretty good. You notice it a little more in street driving conditions, but not too much. And the lockup still works a treat.

On the strip, (assuming you have good enough tyres to stall onto without spinning ), i was getting 7-9 psi with a quick stall at light throttle (since only got side mount cooler at that stage) .

Unfortunately, the 60' timers wernt working on the night i went out. but ET dropped from a 13.8 to a 13.2 However MPH dropped 4 mph

Not sure if this was converter, or due to the fact sitting on the line with boost fried the SMIC sooner and it lost top end......

i have a 2500 stall converter

from Dynamic Race Transmissions

along with my rebuilt box.

shifts are hard as.

its cost $600 for the converter.

Waz will your box be fully manualised after the stage 2 shift kit?

its still a std rb20det box right?

p.s my diff sounds like its copping a hiding if it changes from 1st to 2nd while rolling,you actually need to give it sum so it changes smoother

i don't want to say what i paid (people can call MV automatics for that) but it was just a bit more than what you wrote and that was for the shift kit AND converter

and of course different company means different product.. s they will perform differently..

its not manualised, just sharper changes...

the rest of hte box is standard... still rb20det auto box

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.

      Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.

      @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
