  1. thanks guys i'll have to check my plugs. my friend who i did it with said it might wear off in a week. but i can't stand waitin that long the way it is. it says run it while puttin it in then turn it off then let it sit for 5 minutes, then start it up again. thats exactly what i did.
  2. Has anyone tried the seafoam engine treatment? i put some in my Z and its running really weird. Supposedly it stops in a week and will go back to normal. Who has heard good things about this stuff? I read somewhere you aren't supposed to use it on engines with over 150k on them. Help me out here people.
  3. Any relatively inexpensive ways to up your horsepower and throttle response? Quick and easy things.
  4. Thanks, but I think I'm gonna go to the shop and get it done, maybe even some straight pipes. Thanks for the offer though
  5. I have a '74 260Z and I cut off the muffler. It sounds great now but I lost alot of back pressure. I'm looking at 3 options, Targa exhaust system, Twice pipes system with glass packs or get it done at the shop with maybe a magnaflow muffler. Any suggestions?
