QuestionOkay, I've found a Performance/Racing Transmission Cooler made by Macko, that lists a rating of 29,900. Would that be high enough? Too high?
I've looked into SummitRacing as you suggested, and I've got a garage there, and I've ordered a catalog.
Oh, sorry, if you forgot, the car is a 2000 Dodge Neon 2.0L SOHC w/ 3spd Auto...though I'm looking into replacing the Stock 670 w/ a 'Ultra-470' from Import Performance Transmissions. It lists as fitting all front wheel drive, 3spd Dodge/Chrysler/Plymouth models. So, as far as I can tell it'd just be a simple swap.
And From Fast Fabrications I've found some Longtube Step Design Headers, ceramic coated for $250.
Now, I know I want to get flex pipes, and I have a choice of 2.5" or 3.0"
is wider always better, or would I have a reason to get the smaller?

AnswerOK you're asking me about tranny coolers for automatic trannys- - -I know almost nothing about them. I suggest you bounce that one off the guys at Summit Tech Line.
As far as the headers go I think that's a wise chioce, make sure they're coiated on the inside as well, otherwise pay the extra to have that done.
As far as pipe size goes, you'll be better off with the smaller diameter. The 3" stuff looks cool on the street, but it robs torque at lower engine speeds. It may even benefit you to use a 2 1/4 pipe, but this will require experimentation. Take both with you to the strip, make 5 passes with each one, and compare the times. It would be best to change them between each pass to keep the temperatures and air densities as close as possible. Sounds like a lot of work, but obvioulsly you are after the very best package you can put together.
That's all I know about it, if you can find someone with a chassis dymomometer, you can learn more about what really works.
Good luck
