How much with stock tramission take before breaking?
Got a 2002 GT (4 door) that I'm planning on moding to some degree. I really enjoy running it around the local road racing track during some club events.
Currently purchased a u-bend replacement and the GM suspension upgrade, they'll be added to the car soon.
After that, the plan I have sketched out is (in order of installation):
* Wizaired Cold Air Induction System with 9" K&N cone filter
* GT High Velocity Throttle Body (stage 1)
* L36 HV Intake Insert
* L36 Throttle Body Coolant Plug
* Under Drive Wapter Pump Pulley
* 10% Under Drive Wapter Altenator Pulley
* Random Technology 3" Downpipe/Hi-Flow Cat
* custom 3" exhaust with high flow mufflers
* L36 ER Rocker Arms and Install Kit
* A modified PCM of some sort (gonna be awhile
)
and perhaps a Ported Exhaust Manifold
To the best of my research, this will add somewhere between 40 and 80 HP and more torque as well.
I know that the transmission for the GT and GTP is the same except for the final drive ratio, and the transmission for the GTP seems to hold up pretty good, so I think that I'm going to be OK.
Mind you, I'm not looking to create a drag car, but a daily driver (a sleeper) that's more fun to drive and has some get up and go to it, without sacrificing any longevity, reliability or drivability.
You think that using Mobile 1 ATF is a good idea for this? What's the downside? I presently change the Mobile 1 engine oil and filter like clockwork every 3K miles, figuring that the engine will perform better for a longer time before it will need major work to refresh it.
What do you think?
