Head Gasket Nos

Head Gasket Nos

What is a good psi boost for this engine?

87 Acura Integra D16A1. Last trip to a dyno came back 110HP @3000RPM stock n/a as it is after 21 years of use. Only 89k miles on it now.

On the way as we speak:

-New pistons/rings for a ZC; slightly lower compression than stock
-New I-bar style rods
-New stock valves
-New stock valve springs
-New head gasket
-Lighter flywheel
-New fuel injectors
-New fuel pump
-Pacesetter exhaust header (yea, I'm cheap, but they're easy to replace)
-New 2.25" Catalytic (even though my state doesn't require a cat)
-2.25" exhaust cat to tip
-Magnaflow muffler
-New water pump
-New timing belt
-New thermostat

When I pull the motor:

-Get stock crankshaft checked for straightness. good to 220hp, might replace if needed
-P/P stock A1 header
-header/deck resurface

How much PSI should I use with the least mechanical/heat wear with a supercharger with this setup? I was told 3PSI was good, but I'm wondering if I can go higher. I don't want to turbo or nos.

The answer really has more to do with the compression ratio. Have the heads CC'd and then calculate your compression ratio. If you have 7.5:1 you can run about 6 punds of boost, if you are around 8.5:1 then you need to lower it to about 4 PSI..

also if you plan to run a turbo you need to select a cam that is turbo rated, and the head gasket should be slected with the turbo in mind as well. Im not sure what the stock comp ratio is on your engine but if its higher than 8.5:1 I would consider getting dished pistons to lower it.
