Default Blouch 5.0xtr On Stock Block?

Hey guys, okay so I have tried searching for this info all over the web and have not had any luck. I currently have 2018 Sti with full Bolt ons, e85 running a blouch 3.0 XTR.
I am wanting to swap turbos for something that I have much more wiggle room when I decide to get a built block later down the line. Reason I am thinking the blouch 5.0 xtr is its "somewhat similar to the FP BLUE with the exception it runs 50lbs/min more than the FP BLUE" and one of FP techs stated that would be the largest turbo they would recommend on a stock block due to overkill and the lag of turbos like FP black and etc. My goal is 600-650whp later down line with a built engine. I wanted to get everyone's thoughts/experiences on this turbo please? I understand our stock internals are limited and this car is NOT a daily driver so with the lag being what it would be , I don't think it is an issue. I am not sure when I would even hit full boost on a blouch 5.0 . What is everyone's thoughts? Anyone running this turbo on a stock block out there?

Any reason that you want to stick with a stock frame turbo with such high power goals? There are much better options for that power level. I recommend looking into the BorgWarner EFR series as they're a much better all-around turbo.

Reason I am not going rotated is because itís like 5-6k when I can buy a stock location for half the price and still make good power. Does the borgwarner turbos come stock location?

Dude hahaha...

Why donít you turn it up another 3-4 psi and do ALL the supporting mods and see how long your motor lasts before buying ANOTHER turbo.

If you have the 10cm housing you should be able to eek another 70 Whp out of that, if your motor Stays together.

There are stock location EFRs, but they aren't stock frame. Full Race offers an uppipe and downpipe for them to fit in the stock location. However, I don't think there are any stock location EFRs that will meet your power goals.
