Hi,
I have this toyota tranny wich is made by Borg Warner, the problem is nobody makes a high stall converter for this baby and shipping it to USA to have it tweaked will cost me a lot of money, somebody told me that if I machine the impeller and turbine, or the stator in order to increase clearance, the stall speed will be raised and the converter will work fine, this is suposed to be the mod that is made by all the converter remanufacturers to create high stall units, is this correct? how much should I machine and where? it would be a drag cutting and welding it back several times so I would like to make a good estimate from the begining, I have the tooling and skills for the project, just need the correct info.
Thanks a lot in advance.

Give us some more info....
What is your stall speed now? Is this foot brake or transbrake checked?
How much do you want it raised?
How much motor do you have? Do you have cam specs, stroke, engine displacement, max RPM, shift points, rear gear ratio and tire size.
What is your expected use for this application? What type of driving will it be used for?...........

thanks for repying,
The tranny is in the back of a 1980 1.6 litre toyota 2T engine, it is a street car, has a mildly modified head, headers, dual carbs, stock cam, the problem is it is very slow taking off, it needs a more free revving converter, we are at 6.600 feet of altitude and all help is wanted, the specific question is if increasing the internal clearance of the converter increases the stall speed? it would be nice having it at around 3800rpm wich is a good point for clutch take offs with this same engine.

well, im not intending this to be an insult. but imo dont mess with it. i could see this being a disaster. worst case, something could come apart after you put it back togeather small metal pariticals could be pumped through the trans causing failure. if its your car and you are willing to take the risk go for it , but if its a customer car dont take the risk . send it out.

so am I rigth or not, increasing the clearance does raises the stall speed or not.
thanks
