Finally assembled the motor got the timing right no more rearranged cam caps...Before I go in detail here are possible factors for what could've went wrong...Setup is as follows Hondata S200 Oside Tiger Injectors(Ebay) supposedly 550cc 290lph fuel pump(Ebay also...took a crap the day after official Walbro 255 on the way)...Stock block b20 8.8:1...Cylinder Head GSR supertec .5mm over valves ITR cams(supposedly)...Said and done we were able to pull 163.7whp and 135.3 ft/lbs of torque redline at 8100 with an AFR of 12.66...My tuner said he couldn't get the Hondata to control the injectors and he didn't believe that the cams were Type R's being that other setups similar to mine that he has tuned in the past i.e. have made 185 and 149...also on their dyno graphs the hp curve is still climbing on my i'm falling off...I will post the dyno in a few...Anybody else have similar setups experience any problems with S200 or injectors

 

I think you meant to post this in the NA forums?

regardless 8.8:1 static compression isn't doing you any favors

 

I plan on boosting the motor so I don't mind having 9.0:1 or slightly over 9:ish...Still shold be good for 14psi in theory but those walls won't hold what a B20vtec will make on 1bar IMO...Even despite the 8.8:1 compression ratio it's not so much how much power it was making it was how power was dying off and where in the powerband...So the question I'm trying to get some ideas to is, is this more of a cam issue or improper for lack of a better word fuel delivery via cheap parts...Remember I stated my tuner couldn't control the fuel injectors and my "290 lph" fuel pump both ebay name brands have proven to be problematic for my tune...

 

testing has shown the ebay pumps to be ****... replace it with a brand pump
what brand are the injectors?

the s200 is old tech but it works... have you checked the mechanical cam timing, base timing (distributor), is timing sycnd in the s200, checked ignition system health, plug gap, plug heat range, do you have a wideband, etc

 

You know whatll get you more power ???































A turbo. Take your *** to the all motor section with your ebay rattle trap build

 

I was like hmmm lets see

Daaaaaaaaamn.

YEAH you should be in the all motor, but if wideband was reading correct fuel would be there. Like they said before the compression is not what I would want for all motor. compression test to make sure motor is healthy.

 

Sounds about right for an 8.8 motor. Those motors stock are 10.5:1 or 11:1.
