I’m really new to this page and turbo setups but am familiar with b series and honda quirks in general, excuse me if i don’t know forum etiquette😅 but anyways hey guys, recently bought a motor of a buddy of mine, built by the guy who owned it before him.
here’s the specs:JDM b16A Engine
JG301 cams and JG cams gears

Supertech dual valve springs and retainers

ARP head studs and main studs

BWR Block guard

Weisco pistons 81.5 (9:9:1 comp ratio)

H beam rods

Skunk 2 maf sensor

Innovative motor mounts
bmr catch can

1000cc iniectors (speed factory)

4 bar boost controller

APR rod bolts

GSR Tranny w/ stage 3 comp clutch and lightened flywheel
currently unknown turbo and manifold, but has turbo smart blow off valve and wastegate
socketed p28
and now for my questions, what kind of power would you guys expect to make out of this? is there a good way to tell the size of turbo and brand? what kind of map sensor should i be running? Again, apologies if these questions could be answered somewhere else already🫡

Bump + suggestions for idle rpm, vtec rpm, and launch control rpm would be much appreciated

Idle RPM will likely be between 900 and 1100 for a smooth idle. Once on Dyno, set the VTEC point high like 7000 and tune the low cam fuel table... then set the crossover point low like 3500 and tune the high cam fuel table. Where the two HP graphs cross is the ideal VTEC crossover point. Launch control depends on tire compound, air pressure, pavement temperature, etc. This setting is ultimately what works best for you. To minimize risk on your drive-train, start at a low engine RPM and slowly increase the launch RPM until wheel spin is unmanageable... then drop it a couple-three hundred RPM.

huge thank you bro. super excited to get this on the dyno. when setting a base map does it really matter where i set the vtec at? i plan to pay a service to make me the base map and they require a bunch of information about settings like that

VTEC at about 5000 RPM is a good start on a B16A.
