Stall converters for A340

[2JZR31]

What is the highest stock stall converter can I use for my A340E. My 2JZGTE one seems to stall to 2000rpm.

I have heard than the soarer one goes to 2300, can anyone confirm?

I have also heard that early 90's Camry and Tarago stall converters have a higher stall and may fit.

Does anyone know more about this?

Give QCES a call. They are in Qld aswell. Ask for Peter, I'm pretty sure they'd be able to help you out with info if you can't find anything.

Cheers.

Can anyone with a auto 1JZ confirm how high they can stall to with the brakes hard to the floor and the handbrake on?

[ProjectSleeper]

factory is 2000 to 2100 rpm..

why don't you just get it modified, they usually cost about $4-500 to get done to about 2800-3000 rpm stall

I'm thinking of going custom now. Not sure about the negative effects it will have in drivability and economy though?

[wiso]

driveabilty may slightly be afftected, escpecially in heavy traffic, otherwise it won't really bother you. economy will also be slightly effected, these are the 2 reasons i am sticking with the standard one.

but hey, if you need to launch hard, your obviosly racing it, question is, are you doing it ont he streets, or are you an occaisional dragway, and then again, is the pain in the ass of driving it every day worth that maybe 1 day of the month fun at the drags?

[2JZR31]

That's what am thinking. But if the negatives are not too bad than can live with it. Some people tell me that its hardly any different from stock. I want to cut 11's at the drags.

Not too sure what the difference between 1j and 2j converters are (if at all). Could just be the difference in low down torque.

Mine is the chaser/tarago converter and it is rated at 4000rpm. Not installed yet as I said so no way to verify this yet. Got it from QCES for $360! I was bloody impressed.

AFAIK the stock 1jz converter can be raised to around 2800-3000rpm. If you want more than that, then a pajero housing can be used.

More than that and it is tarago.

Peter will be able to help you though.

I don't think the around the town drivability will change that much with a 3000 stall. Then you have lockup clutch for the highway so no difference there. I can't see a downside If you haven't got one yet, get a trans cooler though. Necessity on these autos.

I am looking into this seriosouly now. I want to DIY the shift kit which can be done without removing the trans, but its easy to loose and mix up springs and check balls as they will fall out from underneath. So I though why not kill two birds with one stone and take it out to fit the shift kit and fit a stall at the same time?

You may have seen the thread on my brothers Soarer with twin VF10's, well we expect lag so will just get a the biggest available that still allows lock up.

I will have to chat with Peter though as to what he thinks will work best. Is he pretty clued up on choosing converters to our needs?

[chris davey]

He was very helpful with mine. Told him about my setup and my issues previously. He originally said 3500rpm but then I told him about my short gearing and how it is difficult to load the engine in 1st and he recommended the 4000rpm for me.

Are you reading my mind here? I have been planning on doing the sf.com/uk soarer forums shift kit for bloody ages. Then I just said that I will go to the drags on the 30th, then pull the auto out, change stally and do the shift kit at the same time

I have done the mod on my spare box but that was with it out of the car and I used shims. I am going to use rods in it this time. That is what Sean uses in the supercrown.

The highest stall converter that I know of that has lockup is mine

Also, they don't usually do this but when I got mine they even delivered it to my door on the sunshine coast for free! Just happened to be heading up this way. Saved me a trip to brisbane

That's tops mate. Yeah I saw your posts in the DIY shift kit thread. (actually you might have put me onto it as bassaholic on PF?) What happened to that thread? It needs a kick along. I have a A340LE which is fully electronic but I am assuming the shift kit will work the same the guys said he was developing a website ages ago but what happened? My brothers is machining up some 19x8mm shims ATM and removing his soarer trans. Thing is we don't know what the lag will be like so it will be hard to choose a converter.

[2JZR31]

I dont run the trans fluid through the radiator becuase it has no provision for it but I got this large trans "V8" trans cooler.

[chris davey]

can't remember if I did. yep that is me on PF if you didn't know. Can't get your name changed over there

Some 2j guys have done it in the US so shouldn't be an issue.

The UK guys have done the best writeup so I will just follow that.

IIRC my shims I used were 8mm thick also. No testing on the box though.

From my experience, I would rather go for a converter that is slightly too high than too low. Not being able to boost off the line REALLY sucks. Not knowing those turbos it is hard to estimate the boost threshold but as people were saying they have larger turbine a/r's than gtr t28's I think a 4000stall would be a safe bet.

If you can wait a little bit I will have more info. on driveability etc. when I get mine in in a few weeks.

Trans cooler looks adequate. I have 2 that size just in case. It does take a little while to warm up (not going through rad either) but that doesn't worry me too much as the auto functions properly when cool and I just take it easy anyway.

[2JZR31]

Yeah I know its you on PF, just couldnt remember if it was you that put me onto that thread. I got my name changed to 2JZR31 from DennisRB30 without being called 2GAYzee31 or anything. I guess I was lucky

Is that UK thread linked to in the US thead? If not I haven't seen it.
