Hello, I recently became in love with my car after I got this h22 swapped
Into my cb7. I'm new to all these car stuff so I don't even know anything.. But I have this problem when I got my car Dyno tuned. Now this is a jdm h22a, so once I got my Dyno results I was completely depressed. My results were 126 hp and 131 torque. This is a stock h22a with OEM headers
And my stock accord's exhaust. The person who Dyno tuned my car said that if I just got some bigger headers and a 2.5 exhaust pipe not cranked, my car will push out atleast over 180hp... I am having doubts... Can anyone tell me if buying after market headers
And exhaust
Will really increase my hp that much?

 

when you got the engine swapped over did you upgrade the intake and exhaust or is that all stock accord parts also. which ecu are you using

 

Any CEL's?

 

well i have a Generic intake, and the exhaust is all stock from the accord. and i have a tuned p28 now...

 

no, there's no CEL.

 

The stock exhuast is reatricting u somewhat but a exhuast is not gonna prevent u from 50 extra hp. I would look into removing valve cover checkin valve lash, tune up I would research the swap and double check the work. Something is not right to be putting out those #s

 

Is your P28 chipped though? Just curious.

Also, do a compression check.

 

the stock exhaust as definitely holding you back a little. either the motor needs a tune up or adjustment or is improperly tuned.

if your running a stock h22 why not just invest in the p13

 

My P28 just got tuned from the place i dyno tuned it. and thats the result they gave me.

 

iunno,, the person who did my swap for me recommended the p28,so that's all i have.

 

well, i just talked to my Dyno tuner Bubba from Do it Dyno. and says there's nothing wrong with my engine.. he really believes that what is totally restricting my power is my H22a running with the OEM headers and stock exhausts with cats..

 

is VTEC engaging?

 

So I assume it's chipped. In order for a OBD1 ECU to be able to tune, it has to be chipped. Can't just be a virgin P28 ECU; otherwise, car would run lean and what not.

 

What intake manifold do you have?

 

I assume he's got a stock IM on his JDM H22A; since, he just swapped it in.

 

I would too but with power that far off the curve maybe not.

 

no way the exhaust is restricting that much power. post up the dyno with air/fuel

 

Well my vtec is a smooth crossover, and yeah I hear it roar.

 

Obviously it's not tuned correctly. Save yourself the bs with this place that is ripping you off and get a p13 ecu and call it a day.

 

I bet your vtec is not engaging

 

Trying to get your post count up?
