Why do you want to buy a stock transmission cooler?

I just did the Davies Craig upgrade and have the stock R34 cooler available. I don't know if I want to sell it though, could come in handy somewhere else from what I've been told :D

Just get the DC Cooler, it's well worth your money :D

I pulled my valvebody out on the weekend and sent it to Mike yesterday. There are sooo many bolts in there its scary. There are about 6 different kinds of bolts too. They are different lengths.

well, when i went to an auto specialist, he suggested that i could connect my existing standard cooler to a secondary oil cooler. with both combined, it should give me the same (or close to) cooling capacity of an aftermarket replacement cooler.

but whats the DC cooler? havent heard anything about that.....

The DC cooler is the Davies Craig cooler... it's a massive upgrade over the standard cooler, well worth the money in my opinion now :)

If you're after the stock cooler though, PM me your offer :D

just a newbie question...

what do these auto transmission shift kits do?

They reduce the shift time between gears (shift overlap) & in turn with the quicker shifts it also reduces wear.

Any chance of a second group buy or whatever? I'm not goin to go searchin through the thread

You could ring up Mike from MV Automatics & see if he'll still offer you the discounted price as a SAU member.

im getting my valve body assembly modified right now by Mike @ MV Auto.

he's been very easy to deal with, and has been a great help with any of my stupid questions too. but best part is that he's called me to update and discuss whats going on - which is helpful as im in melbourne, and my car is off the road for this week while they modify it for me.

as everyone else has said in this thread, Mike has been great!

Yea me too aswell.

I'm keen on getting one in about a month once I round up enough cash to buy one.

Keep us posted if people are interested on these... maybe someone could start one

I'll give Mike a ring and see what the prices will be.

I will also see what he can do as a group buy on torque converters. (nothing too over the top- just enought for a daily driver yet a bit more stick than stock)

Sorry but I was just wondering what exactly does the torque converter do?

What is the purpose and use of a higher and stronger torque converter?

Will it make it any easier on the gearbox... if so how?

Cheers

The torque converter acts as both a clutch (stops the auto stalling when you are stationary) which is designed to lock/stall (or almost lock if you want to be technical) up at a certain RPM. You could consider it as being similar to the manual clutch and easing the pedal out so that the clutch locks up as a certain RPM.

Another benefit of the torque converter is that it also multiplies the amount of torque the engine produces up to the lock point. (and torque wins races, Horse power is for boasting)

A higher RPM torque converter has the benefit of allowing you to have more torque up to the stall point (the curse of high RPM turbo motors has been cured) at the expense of poor fuel economy at any RPM below the stall point.

If you were after a quarter mile rocket you may want to install a torque converter that wouldn鈥檛 stall until 5000rpm, which would suit a car with a big turbo and cams that pulled from 5000 - 9000RPM, but if you were to drive the car down the road at 60kmph you wouldn鈥檛 be at 5000 RMP, so the torque converter wouldn鈥檛 have locked up, and your fuel economy would be awful.

Most people install a much more conservative torque converter that will lock up by 60kmph for a street car - perhaps 2500 - 3000 rpm depending upon the turbos and power curve of the motor.

You will notice the car will rev quickly up to the stall speed, and will have more torque down low, and hence be a lot quicker off the line. With an auto this will also mean your boost will kick in earlier as well.

Hope this helps.

Thanks 4door Sleeper for the information.

So I guess its more to what setup you have on your car.

I only have a VG30 Highflow in my 33 with all the basic mods to support it. I don't think I would need a higher stall converter since my setup is not as extreme. So I guess it would be more useful in a bigger turbo like a GT30 or something.

Guess I will just buy a transmission cooler too keep my transmission alive.

Do you guys think I should upgrade for an auto shift kit?

My goals are only around the 250rwkw mark.

What do you guys think?

Dude you DEFINITELY want an upped stall converter, and the shift kit valve body upgrade - once you have driven an auto with a higher stall, you will never go back.

Basically when you boot it the revs build, but the car doesn't move (much) until the stall takeup point - so basically you can almost never get caught off boost.

However, if you never want to zoom off the lights there probably is no point - but then you wouldn't own a Skyline - you'd be better suited to a Commonwhore :/

But, I am going to wait to save up the full $2,500 to do the stall, shift kit and kevlar plate upgrade to make a 100% bulletproof trans :):D:)

AND, if you're aiming for 250rwkw you WILL need to do this too - I hear the stock trans shits itself at a bit over 200rwkw.

The kit consists of a Valve Body for the RE4R01A auto trans, which includes R32's and R33's and some others (Stageas I believe).

Any chance of a kit being offered for the R34 tiptronic in the future?

Give Mike a ring at MV automatics, he's a good guy and very helpful.

He may have the 34 valve bodies, I just dont know.

      See, that button sounds like perfection Duncan! My eyes really don't like light shining at them from a dash when I'm driving. Being part red colourblind, I've found for most cars that I can change colours on, I set everything to red, so my eyes see the elast amount of colour! I miss normal gauges in cars

      Possible swap on R34 RB20DE NEO?

      By Kapr 路 Posted

      Maaaan so many "little" things  i rly hope my old RB20 would be "ok" and not too bad. I try to learn what and what not do i need. I look at crossmember at it looks different...even parts numbers are different. Wiring and all that i rly do not know...yeah someone mentioned the speedo thing. On that yoke clip. I rly do not know what can and cant be done "custom" so that is why iam asking to know and not be suprised 馃檪  I know what it looks like

      By GTSBoy 路 Posted

      Oh, there's also the gearbox crossmember which will probably be different between the small box and the big box, and the wiring loom will probably need to be modified, because the plugs for the switches etc, will probably be different. And I think the speedo on the small box R34s is from somwhere stupid, like the diff, possibly, so you'd need to work out what needs to be done about that (assuming it is different). I think the thing you need to realise is that the front end of that yoke is a large hollow tube with splines on the inside that mates with the splines on the box's output shaft. It is a dedicated thing - not available "aftermarket". They were made to suit that box, by the car's OEM.
