Once the car hits the stall point of ~3000rpm however, the torque converter locks in and transfers ALL the power through the box. No slipping at all, assuming the engine is capabable of overcoming whatever is stopping the wheels from turning (ie: the brakes). An easy demonstration is to do a line lock. Stand on the brakes and floor it. From idle to ~3000rpm, nothing will happen. As soon as the engine reaches ~3000rpm the torque converter will lock in and the wheels will start receiving the full power. This results in a skid, and cheering crowds, and naked hot chiqs wanting to have sex with you. As is my understanding.

^found on a commo forum LOL!

ps if i get a stall converter will it break my transmission? would a stage 2 shift kit and transmission cooler be enough for my NA auto tranny to support a RB25det conversion?

OK, first of all the original person who wrote that post doesn't really understand how a torque (or stall) converter works.

Secondly a "shift kit" is generally modifications performed to the trans &/or valve-body to give quicker, firmer shifts, etc.

If anything by doing a shift-kit & high stall alone you will be more likely to break things.

What you want to do is strengthen the trans by (depending on your budget) getting an overhaul using strengthened components such as clutch drums, etc, maybe upgrading to kevlar bands & clutch plates, adding an oil cooler (as you mentioned), etc

Really there are a lot of options but the price will soon sky-rocket.

I wouldn't add shift kits or high stalls unless you either strengthen the trans or are prepared to replace it when it fails.

Also there is no such thing as a "stage 2" shift kit.

This isn't Gran Turismo... :ninja:

Some shops may offer varying levels of modifications such as stage 1, stage 2, etc but what is included is likely to change from shop to shop.

Before you buy anything do some research, know what you're buying...
