Vehicle: 91 CRX Si Special Edition
Engine: 93 Integra GS-R 1.7L DOHC VTEC
Modifications: - Generic intake pipe and filter
- High flow catalytic converter
- 2 1/4 inch exhaust pipe from catback
- Magnaflow exhaust

Had a post earlier regarding my 1.7 GSR motor in my CRX lacking power, this is what i found. Muffler was plugged, TPS was reading 0.3V - 4.4V, and lazy oxygen sensor. So, replaced the muffler with my old magnaflow one lying around, adjusted the TPS (hacksawed rivets and installed some torx screws) to 0.47 - 4.61 (closed - WOT), and replaced that lazy oxygen sensor with an NTK replacement.

I finally got around to going to dyno to get some base numbers to work with, this is where i figured out the oxygen sensor must be lazy if you look at the light load acceleration at 3 -4500 RPM you'll notice my A/F ratio was about 15:1 and went to stoich as engine management switched to open loop.

Did 4 runs, first run with distributor timing found to be at 14 deg btdc, then adjusted up to 17 deg btdc and found a little gain in HP but a 7 ft lb gain in torque with final results to the wheels: 145.18hp and 114.14ft lb torque.

Now finally after the above repairs, i have a respectable baseline to start with, planning to go turbo, i've purchased a Walbro HO 255LPH fuel pump, B&M adjustable fuel pressure regulator, Hondata s300 engine management computer.

I'm looking for ideas for this build, and any input you have if you have experience with building and tuning as this will be my first build. Also any comments on my dyno chart are welcome as well. I'll be posting future progress and dyno results in the future as well after modifications when i can.
