Automatic Transmission HP question.

I drive a 1994 Acura Integra LS, my car is an automatic, and right now is 100% stock. When the summer rolls around I am thinking about increasing my hp, but I am curious to know where I should stop as it is an automatic transmission. So in short, What is the max hp you would recommend putting in my car, so I don't destroy my tranny.

Anything simple bolt-on (like, intake, header, exhaust) you should be fine as long as your tranny has fluid in it.

If you bought a turbokit, then your tranny would probably eat itself

Stock you have ~140hp @ the crank. With full bolt ons you should be around ~160hp @ the crank, or 140hp @ the wheels. With a turbo you would be pushing over 200hp to the wheels and that's too powerfull for a stock automatic tranny

try and find a gsr automatic tranny, they are extremely rare but exist, that might be the ticket. the tsx is the only one i know of having a clutch in it to handle the power.

I have a 99 GS Auto and the trans will be strong enough for quite awhile but the thing you will run into is being able to tune it. If you are serious about building a motor I would get a stick. I looked into building a motor but its just not worth building an auto. I am just making mine a clean dd and then going to get another teg for building a fast car. IMO

Also if you go with a gsr head you will have to get the ecu off a auto gsr, those are also rare and expensive

Well once I get all of the bolt on's put in, what are other ways to increase the acceleration of my automatic transmission Integra?

Bolt-ons won't give you +20 horsepower. Not even close to that.

Mteg is building an auto right now, the tranny would be fine, its the tuning that you'll run into a problem on.

The auto tranny will hold 200whp fine. So far the best option I've found is using a SAFC for tuning-which works fine if done right. I was trying out AEM's FIC but I ran into a few problems-the main one bineg that it would not hold the program after you disconnected the laptop. I was getting really good results-around 162whp on a mustang dyno. The auto tranny is slower cause it has way taller gears. To increase performance, have your torque converter rebuilt by Level 10 or pro-tech transmissions-around $500. Another cheap mod is to add a tranny cooler-real simple to install.

Yes a tranny cooler and the level 10 converter is about all you will need. Give the fluid a good flush too. The converter will help your power delivery as well, it will feel a bit crisper. I ran a 75 wet shot on my Auto LS and it took it like a champ. I must say, Auto's do love the spray. An auto is actually a plus on N2O. But if that shock didnt rip it apart on a stock set-up around 80k then you should be fine.

If you do go harder out level 10 sells valve kits that will help you shift quicker. They can even hook you up with paddle shifters $$

It's all in how much you want to spend. If you have the money, Level 10 will build you an auto tranny that will outperform a manual-cost is around $4k though.
