Im running a type r head and type r intake manifold in my 99 si but still on the stock b16 fuel rail and injectors. I was wonderng if my car would run better with the type r or upgraded fuel rail, type r or upgraded fuel injectors and better fuel pump to compensate for the power and air? I have chipped p28 so i would get it tuned later.

But my concern was my cars idle fluctuates from time to time..and sometimes when i fill up on gas it has a hard time starting and idling..i have to give it gas for like a minute. maybe the p28 is the problem?? any help would be great thanks

 

the rail and injectors are the same.

 

also what size fuel pump? woulda 255lph be to much or 190lph ok..im planning to be all motor..maybe spray here and there.. also what size injectors. thanks alot guys

 

oh ok i just saw the rail was like tubular and the b16 is rectangle. I think my injectors are clogged or somethings because i here like a ticking sound like at 4k rpms and up. oil pressure is good, i have a new fuel filter, new distributor, no cel. just an oil leak by the oil pump and that jumpy idle at times

 

bump for some help on this issue?

 

that ticking sound could be your valve train asking for a valve adjustment.. a motor doesn't care what shape your fuel rails is, it only want a the fuel. what makes you think that the ticking sound is related to the shape of your fuel rail or injectors... i would love to hear how you came to that conclusion. unless what you are hearing is pigging, anyways get your car tune and all that bs will disappear

 

nicely said. how i came to the theory, not conclusion, of that ticking sound was maybe my injectors trying to spray but are dirty or clogged.

 

It's more likely that it's your valvetrain that's out of adjustment and not your fuel injectors. Your Si fuel pump is also exactly the same as the type R pump. Fuel is not your problem.

 

ya i was thinking that, because its starting to all come together. I guess im just trying to find an excuse to buy new better stuff...lol! I adjusted my valves twice and have intake at 0.007 and exhaust 0.008.

So the smaller the number the tighter the lash correct? If thats the case im going to put intake on a tighter 0.006 and exhaust on the tighter 0.007.. i thought it was the other way around

 

what about the jumpy idle? thats what made me assume or question the fuel system or something related to it. also when i pump a full tank..problem starting car

 

if you idles is going up and down constantly reset your iac, unplug the iac with the car on and turn the idle crew in your TB down till your car is at around 500RPM plug it back in and is all set, if this doesn't fix the problem just get the car tune.

 

i have a b16a2 TB, i think that the type r or b18 TB have the idle screw correct?

 

^they all do...how else could you adjust idle?

 

maybe im thinking of the fast idle screw. That on integras, on there TB they have 2 screws, one of them being able to adjust idle. i dont know of b16 tb of being able

 

obd2 manual b series did not have the fast idle valve. if you're runnign a p28, try unplugging the evap purge solenoid.

 

Yes i am aware of that, so when he was saying to adjust my idle screw, i was saying i dont have one. i read on an integra forum on how to do that but my car doesnt have it right?

Yes i am running a p28, you said try unplugging the evap purge solenoid at the canester? what would that help..my idle issue or my starting issue when i pump gas? thanks dude

 

fast idle valve and idle adjustment screw are two seperate things, I believe you have them confused.

 

The helms manual gives you correct methods on how to adjust idle. If you still have idling issues, I would clean out the IVAC with brake fluid, or check for a vacume leak.
