Has anyone ever built an Automatic to handle Horsepower??

Thinkin 3 maybe 400 Hp...Don't hate on it just wondering for the wife to make her life easier.

Lookin at a EG...

 

Don't expect to get longevity out of it at that level. Since it is for your wife, I recommend leaving it stock. lol. If you decide to go down that route, you will have some wiring issues with the auto setup that you will need to work out and tuning. Not a lot of companies offer anything to support the Honda auto trans.

 

Ok thanks probably just go 5 speed lol

 

Honda auto transes are just not fit for power.

 

The obd2a to obd1 harness for auto is $250 at rywire.com
Same as above but Manual tranny $75
Tuners dont want to touch them. I am in that boat. Just ordered H22 and LSD auto from HMotors on Monday, then the wife changes her mind and says a manual trany is ok. I bet I am too late to change my order, but I am going to try

 

It's hard to want to touch something there is no support for. You can't adjust shift points with any tuning software as far as I know.

I would definitely try. I'd even take a loss on it if need be. Those H22 automatics weren't exactly know for being tough in stock form.
