I have Tanabe down pipe, hks carbon T.I. catback exhaust, Injen intake with upper intercooler pipe, the hks spark plugs ACT street clutch. and i just got a Hks type 1 turbo timer......


does anyone know if the timer could cause the problem i am having?

Also i'm not to sure about the gapping and my car was running fine with these plugs for about 5000 miles. it wasn't until i got the timer installed that i started running into problems. And about the boost it feels like it wants to build boost but it doesn't, it just starts to sputter when i get to 4000 rpm now. I can hear the turbo spool up if i give it a little gas and make my way up to 6000 rpm slowly but, it's just when i put my foot on that gas it all seems to go down hill. The problem seems to be getting worse since i wasn't getting the sputtering until 5000 rpm before now it's at 4000 rpm

any help would be appriciated.

 

Why in the world do you have those plugs? You should have NGK BPR7ES, not some strange HKS plugs that are a 9 heat range, which is crazy. They probably fouled out and need to be changed. That's like the first and easiest troubleshooting step you always do when you start sputtering under boost...

 

go and get some ngk bpr7es gap them to .026 and install them. let us know if that solves your problem.

 

see told ya.....: ) good luck man
