Here are the specs for my new cars engine, which supposedly wasn't really ever run and was built by learnerspermit.
PS, the VTEC KILLER CAMS ARE BEING REPLACED WITH STOCK CAMS/CAM GEARS. PLEASE KEEP THAT IN MIND WHEN RESPONDING. I am not a fan of the cams at all, regardless, I am sure they are great for the track or for other people, but I plan on boosting one day and these cams are not compatible with that plan. I am on the stock ecu.

Questions for an idiot who has never owned a built motor before.

1. The compression is listed at 11.0, I believe stock is 11.8, is this correct?
2. Is the motor stroked? I don't believe so, but I am very naive, I have owned several boosted, big turbo motors, but never touched the block before.
3. It appears obvious to me that with stock cams this motor should be capable of intense power numbers, is this assertion accurate?
4. How f@#king cool is it that I got an s2000 for 5 grand with this amazing motor in it. I have tons of respect for BC, tons, and have never heard anything but great things about him.


5. MOST IMPORTANTLY, WILL THIS MOTOR BE ABLE TO RUN ON STOCK ECU WITH STOCK CAMS. I HAVE NO PROBLEM GOING WITH SOME SORT OF PIGGYBACK, OR WHATEVER IT'S CALLED IN THE HONDA WORLD, BUT DON'T WANT TO DEAL WITH STANDALONES. SO, WILL THIS ENGINE RUN ON THE STOCK ECU WITH STOCK CAMS? The build seems fairly basic, just a extremely forged motor with extremely well made bad ass parts on it. I am hoping nothing is wrong with it, thus leading to the cheap price, thanks.[attachment=19009:IMG_5572.jpg]

 

1)The stock compression ratio is 11.1 : 1 on the F22 and 11.0 : 1 on the F20.

2)The stroke appears to be stock, since the piston "compression height" listed on the piston sheet is the same as the stock piston and the rod center to center length is the same as the stock rod.

3) The stock cams specs are:

OEM AP1 Cams
Adv. duration: 295 / 309
Dur at 1mm: 247 / 243
Lift: 12.15mm / 11.1mm
Lobe centerline: 98 deg ATDC / 100 deg BTDC

At this lift, the stock head intake port will flow about 300 cfm (results may vary).

This is enough flow to make about 300 hp with the stock compression ratio on an engine dyno (not chassis dyno)and without a turbo. BUT, other factors may prevent this from happening. The OEM intake, TB, exhaust system (w/ Cat. Conv.), etc. will limit the power potential.

4) Way cool !!!

5) You should not have a problem using the stock ECU with the components that you will be using.

 

awesome info! this forum has been great. I really appreciate the help. I've been an ap1 owner for just over a week and every question I've had has been promptly answered here, it's great. very informative.

As for question 4, my question was what sort of power could this engine I have handle. I was told 800hp, I'll never look at number that crazy, but I will be supercharging before the end of 2012, I've heard the stock engine can handle 400whp pretty reliably, so i'd assume with a supercharger with complementing parts, id assume I'd be looking about 350whp and this motor I have would have no problem with those numbers. For now, I am probably leaving the motor as stock aside from bolt on's and itb's. I'd like to be around 230whp, I think I can approach those with a test pipe, cai, itbs, and possibly stage 2 cams from bc and a hondata, I am not sure if the s2000 has the same hondata applications as the rsx-s, I've seen them go around 220-230whp with bolt ons and hondata.


As for now, the car is creeping closer and closer to completion. I got my rear bumper, headlights and my shift knob (lol) all for only 310$ so far. I'm not a poor guy, but I do love a deal. This site has a great marketplace and I should have the car finished for about 750$, putting me at 6250$ out of pocket for a completed s2000 with a built engine, carbon fiber lip and hood. Not a bad deal, and really, after I sell these vtec killer cams, I will have essentially completed the car for free, assuming I can sell them for about $600.

Thanks again, last question would just be in regard to the power potential this motor can safely handle with boost. I guess I might got turbo if I can run 400whp reliably. Crazier than I am used to, I usually aim for 1hp/9lbs power to weight, all of my cars have basically hit that number, this may be my first nutso car, I am considering turning it into a time attack beast in 2013.
