OK,Well i scored another turbo (GT2860RS .84 a/r) and instead decided to Keep both as of right now (may change my mind) but wondering which turbo would you Use on Which car.

1: is my Track car (Coupe Blktop SR) I've been working on - It already has a GT2560 BB Turbo

2: Is my Daily driver w./ Stock T25 Redtop (w/ supporting mods).High Power Dosen't matter either way as its not going to be balls out but wouldn't mid the extra power.

Which Turbo Should I use on Which car: for Track (road race) setup (not nessc HIGH Power so much as Controllable power) Better boost response Heat Reliability,etc.
Or For QUICK nice daily Driveability.

What Mods would I need to make sure they are Good enough w/ moderate boost levels:
480cc's @ least good enough?,(already planning a New MAF N60 or N62),Fuel etc etc.
Track car needs to be Fast but Not BALLS out fast as it needs a Perfect Mixture.

BTW: stock Maf we found already is maxed out when hooking the consult up to my Daily car 2 w/ 9psi.

My comments.

I think you have your track requirements figured out somewhat, but it's still very broad.

Roadcourses could range anything from a .5 mile autocross course to a 20-mile full road course.

You really have to tune your car for the specific track.

I generally don't like forced induction for track use due to excessive temp and more moving parts = less reliability. Even the best turbo will still have some lag.

Also, the bigger the track = need more response because cornering speeds are higher. For short tracks you can pretty much go WOT on low speed corners and still be ok.

If you still insist on a turbo, I would suggest looking for as close to a magic bullet as you can possibly get. Meaning your turbo can be tuned for the specific track to run low boost for response or high boost for power with a boost controller.

Recommending specific turbos is beyond me but I can check with my engine builder and recommend one for you.

I personally prefer larger displacement, low-revving, NA pushrod V8s for track use. Cheap and reliable.
