1991 NA with Complete S5 Engine/Driveline swap

1989 13BT Engine with Series 4 Turbo/Manifold
No Airpump, ACV, PS, vacuum mod done (4 vac lines on complete engine)
3" Thunderfabrications DP/MP combination
3" HKS Hiper Drivers side exit exhaust
Mazdatrix FCD
Walbro 255lph fuel pump
Apexi SAFC
ACT upgraded PP w/ a stock level disk
K&N Intake filter (Stock TID)


With the above set up around what lb boost will i be running, i was thinking around 225-250rwhp, but i might be overshooting. I was also looking at High 13's ET.
-----------------------------------------------------------------
Then I am thinking about upgrading the secondary injectors before putting on a 3" TID. I was thinking 680cc's.

Then a custom FMIC followed by 2 upgraded Primaries

Then a Stage 4 BNR hybrid done to stock blown S5 turbo.

From there i will decide.

What do you think?

Your figure sounds about right to me. Before I redid my engine compartment I was running about that horsepower and was running about a 13.7 in the quarter.
