Turbo Fuel Question

You, sir, are my hero. I'll keep that in mind ;)

Hmm were you twin-scroll? Because as I said the PO was seeing 10 psi at 3000 rpm on an essentially stock 3.0L Toyota 7M-GTE

not twinscroll

HX50 will work well around 18psi and up. I tried the HX55 on my B34 M30 with a twinscroll manifold and it spooled up pretty decent but when it lit up all hell would break loose, it would spin the drag radials at 90mph.
IMO the HX50 is way too big for a 2.8 and the car won't be enjoyable unless it's WOT all the time or using it as drag car.

I'm actually on a gt35equivalent Turbonetics, the big holset was very lazy and late to spool. HX50 would be way too big, I can hardly spool the gt35 below 4k. I creep up to 1 psi by 3500rpms.

Your reliability will be 100% up to your tuning abilities.
I'm at 18psi now and making over 400whp simply because I made a more aggressive tune.

the h1c was lazy? My HX35 spools pretty well on a 2.5L M50... I don't drive the car hard so my latest log doesn't give an accurate number, but I have 7.5 psi boost @ 3473 rpms @ 46.9% throttle. 100% throttle in a high gear sees full boost far earlier and I'll creep into boost by 1400 rpms.

What cm^2 is your turbine housing. Is it twin scroll?

I have the 12cm housing and it is twin scroll, but it's on a single scroll manifold.

H1c was very lazy, it was much bigger than my gt35, it was the large h1c with the antisurge inlet and huge turbine housing.

630's and a PTE 6262 turbo with a billet comp wheel will out flow a 35r by 30%. MS or VEMS.
