2600 Stall on stock engine?

[84GNwith87eng]

My motor is a stock '87 intercooled motor, has 30# 009's + street 93 chip. I'm getting the transmission rebuilt, and was wondering if it would be a good idea to get a bigger stall converter while the trans is out, like a 2000-2600. I plan to get a te-44 and front mount in december, so would this be reasonable?

thanks

The factory converter is rated at 2024rpm's and some have gotten them to stall upwards of 2800. Most stall near 2600. If I were you, I'd call either Bruce or Chris and set something up with them.

my wifes car has a 44 and a front mount and itll fry the tires for 3 city blocks with a 3000 stall 911 at 12 am in midtown manhattan with me driving it .

Prolly thi biggest help is that you are going to have to understand "stall speed" as it relates to a turbocharged car. Gerneally, if a TR vendor is advertising a torque converter stall speed of 2600, that means it'll stall at 2600 RPMs with on e psi of boost. What is important is that the same "2600 RPM stall" converter may go up to 2900 RPMS at a 10psi launch, on an otherwise stock motor. But put that 2600 stall converter behind a highly modifed motor and it may stall at 3200 at 10 psi.

Hope that helps.

I had a stock D5 stall at 2800 behind a very mild 350 olds (edelbrock performer package) in an 84 LeSabre. Stall varies with torque.

So with all that being said, what is the best converter/stall speed for a stock application? I would also like to know since I'm debating on reusing my D5.

Chris, what do you have for an inexpensive converter?

Inexpensive convertors

Speaking from experience, the most expensive convertor is usually the cheapest one you could buy outright trying to save a few $$$ during a rebuild.

If you are going to go through the expense of rebuilding the trans on these cars, even a fairly stock setup, it might be prudent to look for a good quality convertor even if it costs a bit more than some of the least expensive ones out there. This is especially true if there is even the remotest chance of you trying to upgrade other stuff like the turbo, intercooler, etc.. down the road.

Building a good convertor takes quality parts and labor that aren't cheap, and while you might get away with something cheaper in the short run, I had the unfortunate experience of trying to save a little $, only to end up having some of the convertors fins break off after a few thousand miles, and destroying the transmission, on a near stock setup that I don't race or take to the track.

Maybe I was unlucky, but these cars produce a lot of power even stock, and I assume with alchy you are running more boost than stock, so that puts extra stress on stuff that could end up breaking. Do a search on transmissions and torque convertors + failure and you'll see I'm not the only one that has found this out...

Hope this helps you

we have a remanufactured ,restalled d5 that prices at 299.not cheap,but a high quality piece.poston has sold dozens of them without problems.

Chris, how much to rebuild my stock D5? I would rather use my stock GM TQ. Include new drive hub, cleaning, seals, o-rings, washers and balance. What is turnaround time? Do you do all the work yourself or is it farmed out?
What is shipping charges back to Buffalo?

Thanks

we dont provide that service.we only sell them outright .we do save you 15 dollars if you return your core.all convertors are remanufactured by a local company,respectively.
