Well I'm about to pull the trigger on a kb front mount kit with a t76mm magnum turbo. Gonna run 3.5 inch down pipe and 3.5 inch all the way back. Any way I just won't some opinions on what size exhaust housing to go with. Lots of ppl go with the .96ar and like it I believe but I'm keeping my nitrous plate kit and decided to spray this thing out of the hole up to around 5-6 psi with 50-75 shot. So I'm wondering if I should step up to a 1.15 ar to take even more advantage of this or stick with a .96? Setup is going in a 02 ex cab 2wd with lq4 triple 12 cam and a 4l80e with STOCK converter. Gonna run about 10#s

 

i would go with the larger ar for shure...i just changed my setup for the larger ar and turbo and couldnt be happier

 

Any guesses when the 1.15 ar would start spooling without n20

 

my ar is the 1.22 and it spools full boost at 3500 with my circle d a1 converter and 3.42 gears...boost controller helps alot. mine doesnt open the waste gate untill i have reached full boost then it starts regulating pressure.

 

Is this a track only setup? If your gonna be driving it much off the track I sure wouldnt size the turbine housing based on spool time when you spray. Are the .96 and 1.15 both P-trim turbos? How quickly do you want it to spool under casual driving conditions?

 

This is a dd. I going with q trim. I'm also keeping in mind traction so I might need a little more lag delay also. I dunno

 

same here...this truck has been to the track 4 times over the years.it's a bad *** street sleeper

 

biggest ar you can get

 

The 4l80 is gonna help you with traction. I think the best move you could make for your build would be to go with a good 3k converter. If you were planning for one, I would say go for the 1.15 ar for sure. The difference between my stock converter and my yank made a night and day difference on spool time. If i had stayed with the stock converter, i would have preferred a p-trim .96 because the verter wont load the engine enough to spool the turbo as well under part throttle. With the 3k yank and 1.0 ar q-trim, the engine is loaded so much more that this turbo seems like its just waiting to be unleashed at part throttle acceleration.
