OEM injectors with med. oil vs Stage 1s and OEM oil?

I have a 2002 7.3 6-speed with 135k on it. Performance-wise, the truck sits as I bought it. 4" MBRP turbo back exhaust, ISSPRO gauges, and a Superchips 1705 handheld tuner. The truck runs ok I guess. My plans in the immediate future include a good intake (probably Ford AIS), a stouter clutch, and a good chip.

My somewhat near future plans are undecided. I know I want some extra punch, but am limited by PMRs and by my wallet.

Ideally I would like a set of stage 2 single shots, a medium oil class HPOP, and a 38R. I'm afraid that would be borderline too much for my PMRs, and more importantly my wallet.

I know from past experience that with a hot tune, the factory HPOP just doesn't cut it with the factory split shots.

My question is this: Knowing I will be using the factory turbo for quite some time, would I be better off running a stage 1 single shot (160-180) injector with the factory HPOP, or the factory split shots with an upgraded HPOP?

With appropriate tuning which setup would be a better long term, reliable, decently performing setup?

Thanks
Brian

i would do the turbo first, then injectors, then oil. 160/30, srp1.1, 38r is a pretty good 425 horse combo.

I agree. Also the 38r is on sale until Apr I believe at dieselsite for $1300. If you want the 1.15 housing though it will be another $300 or $400.

Do you have access to a scan gauge? I would see how healthy your HPOP is and go from there. My old HPOP was only doing 1800 psi and a SRP-1 made a huge difference on the but-o-meter scale.

The adrenaline has twice the number of pumps in circulation too.

With less than half the issues of the other two.

I'm gonna go against the majority here, you want reliability and a little more power. Mod your stock turbo with a WW and an exhaust housing and leave it alone. Better yet, find a van turbo on eBay, get a EBPV delete pedestal and a downpipe adapter, and leave it alone.

Then install the injector of your choice, and see where your ICP is.

Very likely you'll be fine on a stock pump.

Which turbine housing is best on the 38r? 1.00 or 1.10, considering stage 1's and PHP tunes.

Your choices are 1.0 or 1.15.

And if you choose to go with the better 1.15 housing, than you need to do some homework and make sure you pick up the right part number.

The 38R will need a different 1.15 housing than is used on the van turbo.

I'm surprised some of you guys say to go with a turbo first.

My only real concern is being able to supply the ICP a hot tune will call for. I thought maybe stage 1 singles would be a way to do that and have a slight power boost at the same time. AD splits are very oil hungry.

Is that not a valid train of thought? Why should the turbo come first?
