91 Si upgrades
header will be the best bang for your buck. made a very impressive impact on my lude. pp.com might be down right now...not sure when it will be back up tho...also i have yet to install my underdrive crank pulley, but i've hopping for a noticable difference in pickup.
I installed a DC header on my '88 B20A7.
And gained nothing at all .
I actually lost 1bhp and 3lb/ft torque.
Although it did shift peak power up to 6720rpm from 6590rpm.
I guess that's all down to the US models being 15bhp down on the UK engines anyway.

wat other mods did u have done to the car?
from dyno's of seen.. the uk spec motors put down the same at the wheels as every other 3rd gen.. back in the hp.com days.. a member had an intake on a b20a7 and put down around 109whp, which is typical..
if u actually lost hp from dc.. there mite've been a restriction elsewhere,
