LS1 Z Posted October 3, 2004 Share Posted October 3, 2004 Haven't written in a while. Been driving the car! I was happy with it until I let MAS280 take her for a spin a few weeks ago. He couldn't stop laughing at me and even said he was gonna make a post how slow my Z is Here is the story.... Went over MAS280'S house for computer editing(ls1 edit) and hang out. He asked me if I was happy with the car. I said yes, Feels quicker than my 93 lt1 Vette. After some tuning, let him go for a spin and that's were the laughing started. He said the car is producing 1/2 the power it should. Lacking fuel big time. Tracked it down that day to switch out the 280z pump and put in john's pump. Same problem. At Idle I would have 60 p.s.i., Hard rev the pressure would drop down to 35 p.s.i. Warming the car up one morning at the shop, I started to smell fuel. popped the hood and alot of fuel was spraying all over the engine . The fuel line from the regulator to fuel rail sprung a leak. On inspection the hose collapsed on the in side and broke down. I couldn't even blow through it. Replaced the hose, Now 60 p.s.i. under all conditions. Here comes the power..... Went back again over MAS280'S house last weekend for more tuning. Removed the thermostat. Throught out the day the Z got quicker and quicker. Even Mike is starting to smile. Which is a heck of alot better than laughing. Getting bit by the speeed bug. Gonna look into a cam very soon. Looking for that 11 second range! Mike Knell called me and asked how the car was. I believe his first question was "Fix that fuel problem yet?" Where is the love? I did menction to him my clunking r200 rearend. His solution was take out the solid diff mount and put the stock nissan one in... That lasted one test drive. The diff lifted and took out my e-brake linkage! Back to the solid mount. Ran the problem by MAS280 and of course he had a solution. He gave me a diff mount set up that puts the mount on top of the diff and then bolts inside the tunnell were the straps used to bolt. Right on!! Other than that. My tach has been sent to john's and stilll working on my abbott speedo. Picked up some very nice HID headlights off KASHABI1 gonna install this week. And gonna switch from Shell gas to Chevron to cure a pinging problem at high end. No it is not running lean anymore. JOEY Quote Link to comment Share on other sites More sharing options...

mas28O Posted October 3, 2004 Share Posted October 3, 2004 Did you have time to burn off all of the bad gas? Mike Quote Link to comment Share on other sites More sharing options...
Phantom Posted October 4, 2004 Share Posted October 4, 2004 Joey, On the Abbott speedo. Be sure to solder all your connections. They don't mention that in the installation instructions but if the electrical connections aren't absolutely perfect the speedometer will occaisionally be erratic.
