wrong pheno spacers

[stang67fb]

ok well since a few days ago ive been running pheno spacers for the 1.8 on my klze, dont ask me why cause i dont even know. but anyways i took them off and just put the manifold on with a regular gaskget and there is no feeling in power Gains at all. i still hit the same times at the track and everything. and from the looks of it i say the phenos were blocking all kinds of power specially from my top end. but still i have no power AT ALL beyond 6200rpm's. its like the car just cannot breathe at all above 6200. now i used to be able to rev the ****er to 7500 and still have more power than i do now at 6200,WTH is choking my car.i wish i could show you guys what i mean.please help me!....

wth is chocking your car??? the 1.8 spacers...did you notice the spacers were REALLY smaller than your intake ports? you have the klze intake manifold right with the 1.8 spacers IIRC?

Is the 2nd VRIS opening up? To check stick a piece of paper between the linkage and its stop. IF it moves the paper will come out. IF it doesn't the paper will still be there.

Have you adjusted the TPS and timing?

[stang67fb]

i did the paper test and they both flew out so the vris works also you can feel when they open up. i did a fuel pressure test today and got 35psi at idle and 42psi at WOT which i guess is normal. so the pump isnt the problem.and yes i screw with the tps all the time. seems im tuning it almost everyday. when i use the fan method now though and without the phenos its set at .55 which is kinda low. with the phenos it was at .62 before the fan. anytime after either of those settings now the car revs when in first with the clutch down only a little but enough to be annoying. also i noticed no difference at all at the track moving the tps to .79 with the idle screw up all the way idling at 2500rpms in gear.i ran the same times as before and it still has no power above 6200. it seems like after it hits 5200 you feel the kick from the vris BUT the torque drops off VERY fast to 6000. btw i even tried tying open the VRIS and still have no power up top. so what can it be....Am i the only one with this problem???

are you using the K8 throttle body? I am and I know for a fact that is limiting my top end. My car pulls about the same past 6000rpm, when it should be pulling harder and harder.

klze's suck

[stang67fb]

no im using the millenia TB kl47 and yes for some reason i think klze's suck to for now...but i still have faith cause it was fast for a week or 2 even with the k8 manifold and tb and computer it was way faster than it is now. Oh and i found out that the EGR passage that comes from the #5 port of the manifold was blocked up top in the neck of the TB opening prolly causing me to fail emmisons when the car was completly stock and the reason i had no VAcuum leaks when i had it on the ZE. Because isnt it supposed to leak out of the side of the head when its on a klze??

[TsiMiata]

There is no port on a KLZE for it to leak out of.

I'm not sure if your saying your engine has this port on the head or doesn't.

There not Really smaller, width of ports are the same just a little extra material in the corners. I can't see how you would ever see a difference at the track with or without pheno's. I use them and I don't believe in them.

[stang67fb]

so then what really is causing me to loose all this power all around and not be able to rev to 7k anymore. Could the disty or bad wiring somewhere cause any of my probs?

[DavidOS]

could be ecu related

[TsiMiata]

Does the tach "jitter" at all at higher rpms? If it does thats a good indication of ignition trouble.

[stang67fb]

well i would say it could possibly be the ECU BUT it has ran the same (well ****tier) with the corksport ecu. And no the tach doesnt jitter at all in upper rpm's or anywheres for that matter.

[timpronk]

1. Dirty Air Filter?

2. Throttle linkage binding causing the throttle body valve to not open all the way?

3. Timing is out?

4. Running to lean/rich

[stang67fb]

well it cant be the filter cause i ran it without it and it was the same, timing is at 13btdc, the linkage opens up all the way, ive tested it tons of times, oh and it does seem to run a little rich but its allways been like this.

[stang67fb]

any other ideas??
