Stage 2 swamps injectors. Now what?

The stock injectors on my 99.5 took a crap about a week ago. I bought a set of swamps stage 2 160/100 injectors and am thinking on ordering a boost fooler and BD Wastegate actuator. Anything else/better to do while I have it semi-taken apart? I was thinking on ordering an ATS compressor housing in a few months and a set of gauges shortly.

Gauges should be put in before your new injectors. New injectors without a bigger turbo will = a lot higher EGT's. You need to monitor that at the least. I would also recommend a tranny temp gauge and Boost Gauge.

2000 F-250 XCLB 4x4 6 Speed, PIS 175/80's, ARP's, 910's, CNC Fuel Lines, 6637 Intake, GTP38R WW2, 4" turbo back, Hydra with Powerstruck and PHP tunes. International Up-pipes, ISSPRO Boost, EGT, HPOP and Fuel Pressure gauges. SB Clutch. MB Diesel HPOP.

Ok. I'll go ahead and get a set of gauges.
With that size injectors, would a larger turbo be better than upgrading the stock?

You should definitely upgrade the turbo with those injectors in order to experience their full potential. 38r or SD66 would be a good choice if you want to stay with the factory mount.

38r is a must. the stock turbo is almost at its limits with stock injectors honestly.
if you cant afford a new turbo yet, get the injectors slightly detuned and look into a ww2 or a similar billet wheel.

also if your fuel system is stock, atleast get the fuel rail crossover from riffraff.

What is the difference in the stock turbo and the 38r? Does anyone have any experience with the ATS compressor housing? I've done some research on aftermarket wheels and from what I've seen, the stock wheel is just as good as the aftermarket ones. So I'll probably stay away from upgrading the compressor wheel.

The 38r is a ball bearing turbo whereas the 38 is a journal bearing turbo. The 38r is not rebuildable but the stock one is. The 38r will spool much faster and should be good to 450 to 500hp. Also, some say that the 38r can be noisy to the point of being annoying after a while. I have yet to hear one so I can't really comment on that. I heard that there is a billet wheel that supposedly quiets these turbos down some. The other turbo to look at is an SD66 which is a hybrid of the stock, 38r and van turbo I think. It retains the rebuildability of the stocker and can support even more hp than the 38r due to the larger exhaust housing (I think). This is the turbo I will probably go with (or some variation of it). Hope this helps.

Some of that is correct
The more relevant difference in the 38R is that the compressor wheel is larger allowing more air flow.
You can put a larger exhaust housing on any of the turbos in question to keep drive pressures down.

OP, do you have tuning lined up to run the single shot injectors already? And yes gauges is #1 priority

PIS 175/80's, Van Turbo with EBPV, BD Billet Wheel
Lots of money spent at RiffRaff
Holley fuel pump, in tank mods, crappy riding leveling kit, DP-F6, 5 Gauges+Edge CS in dash, CB radio in Dash, over 100 goofy little mods
Still pretty slow, just less slow now.

That's right. 38r is 66mm on compressor side. That is why I like the idea if the sd66 because it has the 66mm compressor wheel, journal bearings and larger exhaust housing.

the stock turbo wont last last long with stage 2's.
its not if but when it blows up.

and the billet wheels are a huge improvement over the stock compressor wheel.
