So I have a turbo integra ls and when I get around 5000 rpms the gauge needle breaks up. Tuner said its most likely the coil or igniter. Tuner also said that the car ran a little rich when it started breaking up. I've tried 2 different distributors but I've had the same problem. What could it possibly be? I either want to try a new ebay dizzy or try getting a oem coil. Any suggestions/info would be great. Thanks!

 

have you checked your plugs
you can try close the gap a little

 

I have them gapped pretty good already.

 

what is gapped pretty good? how much hp you making? did this just start happening or since you been boosted?

 

I forgot what it was exactly but the tuner did it. It's .28 i think? Making 215whp 202tq and yes it started happening since I went boost.

 

your timing is on? verified with timing light?

 

Yes tuner timed my car also.

 

I'm currently rebuilding the turbo due to a leaking seal. Can that have anything to do with the rpms breaking up?

 

if it happened from beginning then why didnt tuner fix it?

i would think too much or too retarded timing

 

Well he said that it was either the coil or the igniter. I'm going to go that route and hopefully it fixes my problem. Why would it be the timing?

 

your car is too awesome, the RPM gauge freaks out and faints.

 

haha if only that was the case xD

 

the fact that u tried 2 other distributors with perfect physical timing and still had the problem

so im thinking

plug wires or
grounds or
electronic timing

 

Well here's some other info. I now reverted my car back to n/a to get it inspected and the car doesn't do that anymore. Could be something acting up with high heat/power?

 

what plugs are you using?

 

the 7's. 2 steps colder

 

Gap down more went .023 on my ls per sf at 15 psi runs great now. What plugs u using? Ngk bosch autolote ect....

 

ngk. Ok I'll try that.

 

still have the same problem

 

Only 200ish, you can get away with plugs gap of .030

What engine management ? The AEM EMS tends to break up at high RPM with OEM Dizzy BTW...

Why doesn't your tuner log, Stat sync, crank count, cam count, timing errors, injector mS..........etc and pin it down that way.......

POST YOUR SET-UP !!!

 

Car was tuned on neptune. 215whp 202wtq @ 6lbs.



Stock engine except for ARP head studs

Turbonetics t3/t4 .57 trim
log manifold
DSM 450cc's

Tial 38mm wastegate
HKS BOV
2.5" charge piping & FMIC
Walbro 255

 

turbo seals fixed?

with break up so early with such little hp,

weak spark, coil
i know you said your tuner timed the car but i dont trust anybody but myself, i would double check timing
oil vapor getting engine but your not turbo so no leaky seals

 

Ya turbo was rebuilt. Spools great, no leaks. I'm thinking it's the ICM, since it sends signals to the RPM's. I'm going to test the ICM to see if it's faulty. I'm also going to try new oem spark plug wires.

 

swap dizzys with a friend of yours.


its deffinatley ignition.

same issue on my b18b1 turbo.

turned out to be dizzy. well we swapped over complete unit dizzy cap rotor and wires.

oh by the way when i went in to get tuned i rolled up with a vtec dizzy and advanced all the way,

Whitfield racing in UPLAND ca told me you cant use a vtec dizzy.


goood luck mang
