SBE 302 Turbo selection?

[98stangv6]

I am putting together a budget turbo kit for my SBE 302 and planned to run a cheap GT45, but I have the opportunity to buy a Borg Warner S366 at a pretty good price. I already have the GT45, but am worried it won't start building boost quick enough. 1) Do you think the GT45 would pair well with the 302? 2) Would I benefit more from the S366? 3) Also open to other opinions.

Setup is SBE 302, TFS 170s, 4150 EFI intake and elbow, E85, non-intercooled, TKO600, 3200 lbs.

GT45: Trim: 69
A/R: .66
Inducer: 68.7
Exducer: 97.8*
Turbine:
Trim: 92
A/R: 1.05
Inducer: 87.4
Exducer: 77*

S366: Compressor Wheel Inducer Diameter (mm): 66mm
Compressor Wheel Inducer Diameter (in): 2.6
Compressor Wheel Outer Diameter (in): 3.6
Turbine Wheel Outer Diameter (mm): 80mm
Turbine Wheel Outer Diameter (in): 3.14
Turbine Wheel Exducer (mm): 73mm
Turbine Wheel Exducer (in): 2.89
Turbine A/R: 0.91
Turbine Inlet Style: T4
Scroll Type: Twin

The gt45 will be a little laggy but the s366 should make boost quicker and be plenty for your set up. All depends on hp and et goals. But with a stick if it were me, I'd run the s366.

I gotta ask- whats the SBE in "SBE 302" mean? Never heard that one before. Small block engine?

Id run the S366 also. The 1.05 A/R on a stock bottom end will be very slow to spool.

Out of those two I would go with the Bog Weiner 366.
