I have the 197hp AT RX8 and want to modify my engine to about 300-350 HP... is this possible? and if so... how?

 

I'm thinking maybe you could get it up to 250-260 MAYBE but even then it would take a lot of money and work.

 

greddy has a turbo kit. re-amemiya also has a turbo kit, specifically for the AT. 300~350hp, why?

 

No data to back this up, but I don't think the AT would take this power w/o major modifications to the drivetrain. There is a reason we didn't get the high power engine out of the gates. The turbos coming out sound good, but will probably only bring you up to the power that MT has stock.

 

Add a transmission cooler. Best mod in the universe for an ATX.

 

Is this a hard install and at what cost?

I've already installed a CZ unit to my auto, K&N intake, and most recently a Borla exhaust. Sounds great and has a bit more power than a stock auto 8.

 

Most stacked plate coolers are around 45-50 bucks. You'll usually need a few extra feet of 11/32nd hose, and some nicer clamps. So around 60 bucks. Difficulty of the install is based on where the stock radiator cooler hoses are running, and the distance to the transmission.

 

how did you get the CZ unit to work with your auto?

 

Where can I go get the AT tranny cooler installed?

 

Whuuuuuuuuuuu?!?!? I've been waiting for developments on this. I hadn't heard that someone had figured out how to use it on an AT.

 

Guys:

Please follow this link to the CZ unit and using with auto 8's:

Just checked out the thread and replied. I think it's great that you guys are pioneering such a development.

Btw, was the AT tranny cooler hard to install? Will Mazda void my warranty if they see it during a checkup?

 

If I install a transmission cooler will the service techs bitch aboutit and void my warranty?

 

Not as long as you install it "in-line" with the stock radiator cooler.

The stock cooler heats the fluid (preventing it from being overcooled) while the stacked plate keeps it at 180F-160F, right in the sweet spot.

You can always talk to your dealership before hand about it. Its a longevity/consistency mod. It greatly extends the life of the transmission, and allows for more consistent shifting as heat is kept in check.

 

the best mod you can do is trade in your auto for a manual :/

 

Will this horse ever die? Its a bloody mess on the side of the road and some people still feel the need to kick it again and again....

 

Yeah thanks for the thread crap.... none of us here realized you could actually trade in one car for a different version of the same car, thank God you came in to enlighten the rest of us.

 

Here is an IDEA lets compare cars son.
you make more horse power what ever and those extra ports by the way you lose a whole lot of power and I mean a lot of power when you go any where over 8000 RPM and save the BS look at any ones DYNO and up until 6000 RPM the auto is the more powerful car keep in mind the 6 port was not used in the turbo 7 for a reason say I am wrong dare ya

cry me a river

 

...wow...

 

Huh?
