It depend on the type of fuel you will be running. If you have e85 available, get a set of 1600cc or 2000cc injectors with something like a 320 lph fuel pump.

If you do 93 or 91 octane, maybe 1000cc will suffice with a 320 lph also. And I don't know how big your rail is, but a beer can -8 would be awesome.

You could get a solid 6......and I don't mean 600 lol jkjk it's honestly hard to determine power just from someone's build. It depends on the tune and conditions but could do 400/500 range

Those 850cc injectors will run out on you on regular 93 around 400whp. The HX35 and your Walbro 255 will run out close before 500hp. Your stage 3 cams are helping your top end there, though.

Injectors are getting cheaper now though! Found a used set of siemens 2250cc for just about $500, good for E85 too.

I think the home could do more than 500, especially t4. Fuel pump could go with an or mk4 supra or the aem one. I would think 850 could do more than 400hp. On evo 550cc are good to mid 300

Ah didn't realize T4 Twin scroll. Maybe a little more, then. At 20psi on my T3 HX35 I was sitting around 400whp and injector duty cycle on 93 somewhere in the 80% range. This was on Precision 85lb injectors. I wouldn't feel comfortable going much higher on the duty cycle where I keep my tune - a boost spike could starve fuel since injectors can't keep up.

I'm going to say the Walbro 255 will take you to around 500 assuming you're running E85 and know exactly what you're doing on the tune.
