LOL. Since I've owned one I always try and steer people clear of them. They are junk and anyone who is considering one needs to skip it and buy a full-size. ;)

Might just have one already...

I need valvetrain mods....

Have to say though, beat on it for an hour today.

Didn't see the aero flashing at me saying it was seeing 1* of KR or more.

Very impressed.

Once you get to a 3.0 pulley the ic becomes a moot point. ;)

For a mild setup it will get the job done. But who has a mild setup on these cars? Once you start adding mods and hear the blower scream bloody murder it's hard to stop. :th_skull:

Next is my awesome PCM that came with the ct turbo kit I purchased from Kuntzie. In laymans terms it's junk and is what's causing the spariodic cutout issue. They're 99.9% sure it's an internal issue. Thanks buddy. ;)

So to remedy the situation I will be purchasing a tuned PCM from ZZP.

Damn, glad you got it figured out though. I laughed at the FLAME SUIT.

I have several remedies in mind...

Im kinda going through the same promblem. Well about 2 weeks ago i went to go start my car and it wouldnt start so i thougth maybe it needed new plugs and wires cause they seemed kinda old so i replaced them and still wouldnt start, so i checked the fuel rail and there was no fuel pressure to the rail and i didnt hear the fuel pump turn on so at first i checked the fuse and the fuse was good so i ended up switching the realys around the fuel pump and the the fuel pump speed control then i turn the kee then heard the fuel pump turn on and the car started. then the same thing happens if the car sits for a few hours but sometimes it takes few times switching the relays around for the pump to get power. Then one night I was on the highway I could feel my car bogging then it died everything was still working just the engine just shut off, pulled over then turned the key off and on a few times then turned it over it started up i gave it some gas then it quit again so then i got out pulled the relays switched them than bam fired up drove back home with out any promblems. Should I get a PCM tune? Fuel pump? or whatever someone help. :th_lipssealed1:

could be the fuel pump. have you tried the fuel resistor by pass deal to rule that out??

Another issue I was having is the fuel pump relay would become disconnected from the pins on bumps causing it to cut out like it was losing fuel.

If you don't have a fuel pump rewire then try the above method posted with the fuel pump resistor mod.

You should double check the battery to see what power it's putting out.

Okay thanks so much. I don't think the relay comes out because they all seem to be tight. But I'll try the resistor mod and see what happens thanks for the help

not a problem sir. may or may not do the trick, but if it doesn't then you know what it ain't. ;)

Well I changed out the o2 sensor on the manifold and so for the car hasnt acted up(knock on wood) i didnt bother changing it because I wouldnt think it would effect it. So i dished out thr 62 dollers for one and she's now running like a champ :)
