I've recently swapped a B16 into my EK, and am running a stock Si computer. Car seems to run normally, but engine sounds a bit off during idling, almost like a tractor. Idle isn't irratic, once warm it stays at about 800rpm. I'm not sure what the problem I have is, but here are the issues:

-Fuel pressure gauge reads 45psi when system is primed, but when I start the car it jumps to 70psi
-Car has no power past 5000 rpm
-Car feel super slow, slower than my D16 that was in before the swap
-Compression test read 185/210/220/210
-When I pull put out the plug for cyl1 while running, the car's engine has no change, however when I pull out 2,3 and 4 (while leaving the rest in of course) the car dies almost instantly. I know for sure I have a spark though, but from what I'm guessing there is nothing going on in cyl1?

My guess right now is that the fuel injector in piston #1 is clogged but I want to hear your input, if any.

*Note: spark plugs, wires, rotor, cap, timing belt, water pump, fuel filter, thermostat have all been changed with brand new ones before the swap. Only put down 120kms on the motor so far.

 

Did you check your ignition timing with a timing gun?

 

^Yes, ignition timing was set perfectly with a timing gun. Forgot to mention that.

 

I'd try swapping one of the injectors in place of number one to test it out. Maybe you got a faulty spark plug wire? Have you checked to see if the firing order is correct as well?

 

I double checked with the Helms manual to make sure I had the firing order dead on. Z pattern, and #1 starts where there is a "C" on the dizzy cap.

I'm picking up new injectors from a friend tomorrow, also gonna grab a new FPR from the junkyard off a random B series Honda, and hopefully it may fix one of the problems.

If the car still feels weird, I'm going to check the harness pinouts for continuity (although it's an OEM harness off a '99 with vtec, and also the ECU is oem '99 Si (P2T I believe it was). I can't think of anything else possibly affecting this issue.

 

CEL's?

 

No CEL's at all. Had one for a bad IVAC unit, but I replaced it and nothing since.

 

Replaced injectors, and still nothing. I can smell fuel on the spark plug so I know it's getting fuel. Replacing the FPR today because I'm pretty sure that the spring inside it is done, and that's why the pressure reads so high.

I think my last resort is doing a valve adjustment, if that doesn't fix it then I'm pretty sure my piston #1 just dead, and I'm going to need new rings.

unless somebody has any other suggestions?

 

ok, so I can't install the FPR until I get a 98+ style fuel rail, my fuel rail just won't let the fpr fit because it ends up hitting my runnings (Skunk2 manifold).

I'll probably get one by friday, and post an update.
