With the 160/80 or 160/100 injectors being such a hot choice, I suspect that the 63mm or maybe the 66mm would be the optimal choice for those injectors?
I believe the GTP38R is 66mm right?

Your response time is great! I should hire you for appliance maintenance or something...

I just happen to be at the computer right now
Yes, the 38r is 66mm on the compressor side

I never got this Sous. You would thing the 6spd would build rpm's faster then the auto there for the 1.0 would be the all a round choice. I have the 1.0 with stock injectors and love it. Soon to be changed, but I've said this for ever. Oh I have an auto.

The nice about working with KC on this is if we think it needs a 4inch intake or a 1.0 housing (for towing heavy) he will send the parts and we will test. He is determined to make these the standard drop in option.
Sous I have a 1.0 housing if you are interested and wanna give it a try.

I'm starting to like the options of the KC turbo, seems like it would be a great bolt on option, EGT's will be my main concern if these turbos show some good #'s I might consider a conversion on my OBS. Post your findings my friend I'm interested as well.

How much of a pain is it to replace the up-pipes? Trying to decide if it's worth it since I'm a little short on cash to spend on the truck after the turbo and new front brakes.

If you are taking the turbo out, then do the up-pipes. Replacing the pipes is easy with the turbo out, and impossible with the turbo in.
The Dorman up-pipes are a good and cheap fix for your problem.

Ok, since I haven't ordered parts yet which turbo reinstall kit should I go with on riffraff? There is a turbo reinstall kit 99-03 and a turbo reinstall kit GTP38? I plan on pulling the pedestal so I can delete the ebpv components if that makes a difference

I currently have 175/0's and previously had 160/0's with T4/S366. IMHO, this is the perfect combo. I would not consider anything 'smaller' - especially with bigger nozzles.
One of of the trucks I just finished has 238/80's and T4/S369 and that truck friggin' RIPS!!! Driven conservatively, you'd never know it was a beast - but put the hammer down and tire life will suffer... (that guy called the day he got his truck and asked if there was a lower power setting for his chip - he was in lowest HP tune 'heavy tow'. Lol. )
We'll have to see what kind of feedback Charlie gets about exhaust housings. He sent me a 1.0 AR for the 369 and explained that some folks had surge issues 'in hotter tunes under some conditions' using the .84 housing. The truck I'm using it in will not even get 'hot tunes' and I'm more interested in fast spool than top end HP.
That said, there's a BIG difference in auto vs manual trans. The auto can handle a 'bigger' charger because TC slip and downshift will spool WAAAAAY faster than 6spd can. I had the same engine (160/0's and T4/S366) in my Excursion with BTS and in my dually with 6spd. The difference in SOTP's power was huge! The X would bury boost gauge at 3/4 throttle from hwy speed. The dually takes awhile to get there... It's possible the smaller AR would help the 6spd with all other things being equal.

They are notorious for flattening, hardening, leaking, etc over time.
FYI. RiffRaffDiesel has pedestals without EBPV for under $100 (the Garrett brand is more expensive). But you'd have to use a fooler or something for the solenoid to avoid a code.
If you have taps and tools, no worries, but an option if you don't or not wanting to mess with it.
