So im building my 99 gs300 to a NA-T. I'm not looking to make massive power, some where around the 250rwkw mark. i have a tranny cooler all ready hooked up to help handle the power but off the line/rolling gear changes are extremely slow and take a while to go down a gear.

Now i know its automatic but i previously owned a 00 Toyota Chaser and the auto in that was awesome, would spin the wheels all the way up to the end of 2nd gear and now jumping into this its just so sluggish.
is there any thing i can do to it that wont break the bank to much and without going to a manual box?

Are the Aristo auto's any different to the gs300's/will it bolt straight up?
any info/help would be great.
Thanks, Adrian.

 

no one at all?
