91 B18A1
Intake/Chikara Header/2.5" exhaust
fuel pressure regulator
Crower 3/4 race cams, .440 lift

I dynoed this a couple of years back, how does it compare to similar setups?

 

that seems pretty good considering the 91 has the 130 to the fly horsepower rating.

i'd say some port work, high compression, fuel upgrade, and a better header will yeild some good *** numbers!

 

Those are some great numbers for a nonvtec with only the listed mods.

 

Wow.. completely stock internals? so just stock head with cams and bolt ons??

 

I had a B18B with I/H/E,AFC,FPR,and Crower spring, retainers, and Crower 405a, and it put down 158 @ 127 @ 7500rpm, then I put Tec2 with nothing else and it made 168 @ 128 on a stock bottom end. I had the motor bored .20 over with 10.5 piston and it put down 178 @ 138. I ran 12.8 @ 106

Yeah, the camshafts made all the difference. That and turning up the fuel pressure. It turned it into a totally different car.

nonvtecallmotor, that's a nice setup you got How high do you rev it to?

I had the Crower 404 cams, but I didn't upgrade the valvetrain like I was supposed to.

damn...........did you bend a valve or what?

nice numbers!!!

 

I put in a PYR ECU for an 88-91 Si and it had no rev limit after the dyno. I missed second gear going down the track(bad synchro) and thought it was in gear and got back on it. It ended revving up over 8 grand. I cracked one of the cam bearings and a couple of the valve lash adjusters came loose.

On the dyno with a stock LS ecu it would cut out at 6800. After the PYR ECU I revved it to 7500 rpms. After that it would just lose power, probably valves floating.

After over-revving, I sold the camshafts to a friend with an Integra. I'm working on a turbo setup for the LS now.

Here's a timeslip for the cam, 3 days after the dyno...



And here's the car...



Yeah, It looks like ***.

Now it sits waiting in the backyard, I've added a Skunk2 intake manifold since then. And it definitely needs a paint job, the three color things not working too great.



It'll be back together before summer.

 

I reved my 1.8's to 8500 rpm. My 2.0 thats in my car now goes to 9000 rpm with stock rods. The 2.0 made 198 @ 148 nonvtec @ 12.4 @ 107 in a 91 si. my 1.8 where in a 91 hf that was alot lighter.
