I am new to the forum and have many questions. I have recently taken on a new project i stumbled on, its a 1990 lx with a 347 stroker from ford svo block, probe rotating assembly, trick flow race heads, trick flow upper and lower intake, 42 mm injectors, and a 60mm turbo. Everything i have is new and never been started. I am looking to find out what size throttle body i should be using for this build? I have a blow thru mass air. If anyone has any suggestions on any of this please let me know.

42# injectors are going to be your biggest hindrance on that car. I would recommend stepping up to 60# injectors.

also, you should match your TB size to the bore of the opening on the intake.
Depending on which TFS intake it is, you might wanna change it.

+1. that turbo will hold you back as well. 60mm is pretty small. itll spool really fast but will run out of breath at the 500-600fwhp mark (depending on the turbo). fwiw, i run twin 57mm on my 331

It's a HP Performance turbo system says it's capable of 700 h.p. on there web site.

thatll be fine then. 9 out of 10 people who post about a turbo they have its a low dollar one that doesnt make the hp that a quality turbo makes of the same size.

So i take it you are familiar with their products? i just finished installing the aje k member a arms and coil overs and i'm getting ready to install the front spindles and brakes once we finish powder coating them. I am also looking to pick out a management system for this set up any ideas?

Its capable of that with the upgraded turbo. Upgrade to at least the t66 at the minimum, and depending on power you want to make the t76 would be a good option.
You said you have a 347 with heads and the supporting mods, so the 60mm turbo will choke that engine up, the 60mm is for a stock engine.
You fuel system needs to be up to par as well.

I'm lowboostint76 over there btw.

To the other guy with the twin setup, looks like a nice setup, I love the twins I'm running twin 60's on a 351w based setup, but may need to go bigger now that I added some more cubes under the hood with the new setup.

I have a 347 that I have been contemplating going to twin turbos. I'm only wanting about 8-10 lbs of boost with very fast spool time. What turbos should I look for. This is in a 65 mustang and I'll be doing all the exhaust and intake fabrication myself. Are there any medium size turbos from factory cars I could look into to use?
