got a b16a1 in 1990 civic hb

 

Depends on mods but most put down an average of 140ish whp

 

ok cool so its about 20hp less

 

More or less but it depends on mods and the overall health of the engine.

 

91civic,
what u recomend for exhaust piping size with skunk2 manifold and throttle body
and dc header.

 

Mine makes 160hp and 118tq on our dyno.

Like I said depends on mods and engine health. By the way those are good numbers for bolt ons.

I'd recommend 2.25" or 2.5" piping at the most. 2.5" is pushing it though with just bolt ons.

 

cool thanks

 

You guys aren't gonna believe it, but all I've got is short ram intake, DC 4-1 Header, 2.5" Header-back exhaust (no cat or resonator), and a chipped PR3 ecu. Can't explain why it did so good, especially since our dyno is a Dyno Dynamics, which is a load bearing dyno rather than a Dynojet so numbers are typically lower.
