    I read the topic That dragon fly started maybe iam simple but my plan was to measure the before and after valve train weight and figure the difference as a % then subtract that from the valve spring tension and order springs

    Thank you all for your input I have titanium retainers locks and DSI valves from Datsun spirt I have a good unmolested. Set of rockers to put in but just enjoying a little time off work and waiting for the machine shop have a press with a tension gauge and was going to make a fixture to measure the deflection at the tip and what it takes to break it compared to a stock rocker here is a pic it ready to polish 66 grams

    I never dynoed it the guy who had this before me got 330 at the tire and he didn't have it any were close to right I am guessing 300 to 350 I had it to 18 and it would spin the tires in 3rd the lag is controlled by the secondary's with springs and too light of a spring makes it almost un drivable I got it running good with the wide bad o2 and the percys metering blocks make it so easy to tune that's what all the trouble is with these kits is the carb the power valve is reversed on this one and it richens under boost cruising I was getting 28 mpg on the hwy

    L28 DEATH rattle!

    If you think its detonation get some copper tubing and a cheep stethoscope from harbor freight pound one end of the copper tube flat and drill a hole in it bolt it on the motor close to the head were the heater hose runs is good run the tube into the car and hook up the stethoscope hose to the tube if you here detonation you know its timing if you don't a least you wont be guessing there are electronic versions of this that I own but I still use this for tuning

    New turbo Fail

    I talked to the turbo shop today they said there is a chance the carbon seal is ok and recommended a .060 restrictor I am going to plum a temporary pressure gauge to the turbo to make sure
