Well finally got the car on the rollers today. And good news it made it home under its own power, alot more of its own power.
1992 1.6 5spd
150K stock motor
Greddy kit with the only remaining part not upgraded being the turbo
Tony's 2.5" DP to 3" cat to 2.5" exhaust straight through muffler
Stripes intercooler kit
Braineack MS with EBC boomslang
CLutchnet 3X PP and 4 puck sprung disk
Had a hell of a time making the EBC work smoothly but we got it. Added spring to help the WG. Got it to make 12-14 psi steady. After 20 or so pulls on the dyno made best of 189 Hp, not to bad but I was really hopeing for over 200. Its got a hickup at about 4500 rpm that we could not iron out, popular answer was that it was an ignition miss and would be solved by closing up spark plug gap or new coils. I'm open to ideas. The tach jumps when it happins.
But I got to tell you 189 hp in this light of a car really felt great driving home. I'm sure its faster than my mildly modded 5.0 DD.
I have a graph and I'll get it scanned in the AM and post it.
Anyone want my datalog let me know I'd be happy to let some if you experienced guys look it over.
Any bets on low long the rear lasts? Auto-x Sunday!
Thanks for all the help getting this project going!
Post a screenshot of your timing map when you get a chance. Interested in seeing what you guys came up with. Considering Ben made close to 250 on the greddy kit, maybe that was 17 psi though. I still think you should be at 200 at 14 psi.
Have the dyno plots to load up?
The only thing 3" is the cat, figures that would help flow.
My concern is the turbulance caused in the exhaust stream by the abrupt change in exhaust diameter. May not have as much factor as I think, but it was good for a few hp on an NA honda/acura motor.
Look at the exhaust stream as fliud, that fluid will most likely follow the bottom of the pipes. As it hits the lip going from 3" to 2.5" it can cause a swirl effect, but not a good one.
I understand your thinking, and I would not say anything unless I had seen it myself before.

add a .1uF cap from js8 to ground. gap plugs at .30"
