93 Civic Hatch EG DX with 98 us H22A4,p13chipped (spoon),saturated
injectors with no resistor box,ported,DC header,2 1/4 exhaust,intake,prelude trans.13"steeles only ran a 15.2 at 93mph something seems wrong . Drives ok but it has a slight hesitation low rpm, uses a full tank of gas every 200km's. Running 255lph pump stock reg. at 40psi. ANY IDEA'S why my car is so slow.I was told it should be in the 13's at 100mph.Could my timing be out using h22a4 distributor with p13. Any suggestions would be appreciated

 

Yes, it could be your timing.

Pull your spark plugs to make sure you aren't running too rich/lean/detonating. I was running lean and detonating at stock fuel pressure. I ran .3 secs faster by adjusting it two points up.
Btw, that DC header is ***. You'll want 2.5" piping.

What was your 60ft at the track? How many times did you run? What Kind of intake? Did you change your spark plugs/spark plug wires/dizzy cap and rotor?

 

40 psi on saturated injector's is waaaaay too low. It should be in the upper 40's I believe.

 

i'm running new stock plugs,nology wires,new cap&rotor.checked the plugs,electrode is light tan color but outside rim of plug is carbon black.I don't think the header is holding that much power back.Custom intake 2 1/2" kn filter.Ran two runs at same et&mph very little wheel spin.Sorry i don't have the slips for 60ft.

 

Check your timing. It can create a huge loss of power. Any CELs?

 

sorry with reg. unpluged 50psi

 

Compression Test. Leak Down. Any smoke from exhaust? Any strange sounds?

 

No cels.But dizzy not adj. on h22a4 1998

 

comp. at 230psi across the board

 

Crappy motor maybe? Last thing i can think of is to get it on a dynojet to get some objective numbers. That compression might be just a smidge low, but it's pretty darn good.

that is definetely an issue there....

i have the same ecu. and i had the same dizzy,. with that slight hesitation, it is usually do to the timing being off...

the p13, being obd1, u need to adjust the timing.. but, with that dizzy, u cannot...

what i did:

we had to notch out the bolt holes
(turn them circles into ovals/ we just used a round file, since its aluminum, its not that hard to file it down)
on my dizzy so that i could twist it a little, and in a sense adjust ur timing. someone told me that this would not work for some reason. but i did it. and it worked. sooooo.. u might wanna try that..

 

Checked timing,14deg.So no reel need to modify dizzy.When the car is cold it feels more powerful on small lobes then when its warm it lacks,Backfiring on decell.

 

Mine does the same thing, exactly.

 

So is this 1/4mile mph normal for this setup?My friends 95 si coupe ran the same with me driving,less mods&lt;b16 i/e

well.. not really... i ran a 15.03@94. or somehting like that... with less than u.
i had..:
jdm p13
shorty intake
gutted interior. thats it. (bad bad run for me though)

 

I guess i just expecting more.Everyones talking mid 13's with this setup,or spining till half track. (hondaZvic)Checked your rides 600F4i nice! I ride a F4i on the track&03gsxr 1K for the street Maybe that's why the car feels so slow.

 

hehehe.. that'll do it.
how long u been riding for?

 

Bout 13years I'm new to this honda stuff cars i mean lol .I thought i'd try this swap and i'm not that impressed whit the outcome.

 

oh.. it just takes time to get used to it... once u get it down.. they are all the same basically...(swaps i mean)

13 years riding..
im just at 1 year now

 

hondaZvic: Do you have an h22a or h22a4?

 

a4

 

(uncle)You running the h22a4? Does any body no if senor outputs are the same between h22a&h22a4?Could the p13 be reciving the wrong inputs to create the lack of power?

I don't think that's the problem. Do you have a fuel pressure regulator or just the gauge?

 

I just have the stock reg.Pressures seem to be within spec for stock engine but i'm also using 255lph intank pump for future turbo use .It was doing the same thing with the stock civic pump.

If you have a walbro 255 then more than likely you running rich. I have almost the exact same setup as you and my fuel pressure is at 60 psi with vac. hose disconnected.
