Actually when you mill a head or block and lower the cams it retards. Adding thickness to the HG and raising the cams will advance the cam timing. You should have went the other way if you were trying to get it back to stock.
Stock valve springs don't loose seat oe open pressure. I measured mine (180K+ miles) when I was putting in CompCam springs, was using a Rebic LC to increase revs. I checked seat and open pressures. I don't have the specs on hand but they were within 2 lbs from stock pressures. I really doubt you...
Copper spray is not needed on new gaskets. Reusing them, yes. They come with a viton coating that seals them when new. I have a MLS HG's on an engine that had 180K + miles. It held for over a year at 24 psi until a case of deto. Alot of new cars come with MLS HG's. The surface doesn't look any...
The 7m ignitor will not work with it. You'll need an ignitor from Haltech or get one from a Volvo S90 3.0l. I'm considering the same setup and found this on a Haltech board.
On hot wire afm's the oil can collect on the element enough to cause problems. It is common with 3.4 Tacomas. A little brake cleaner makes it better. You need the oil do stop the fine dust.
You don't need 550's to run a lex. I did it without one and a friend is doing it too with 440's and Lex. We both have widebands and neither had lean issues. He runs a full 60-1 T4 and 18 psi also. He ran into fuel cut with the lex at 17 psi so is now running an FCD too. I would buy a wideband...
Hmm, I've been doing it (500+) for 2 years without any problems. WTF are you talking about fuel maps for now :3d_frown: ? WIDEBAND, nearly everyone making power has one and a way to tune there fuel curve but you. When you achieve that kind of power let us know how much you've spent on cams, ecu...
Define useful. If it's running a P trim or larger on the hot side it just isn't coming on until 4300-4500 rpms. What truck turbo are you talking about? :nono: A turbo that will make 500 + rwhp will have alot lag on a 3 liter motor. A friend of mine asked why I always hit the rev limter in 1st...
Then this mod obviously isn't for you. Power bands change with big turbos. Some of us don't have full boost till 4500 rpms and need a little more rpm.
I was one of the guys that had my ecu (89') modded by him. He did it twice and it still stopped at 6600 rpm both times, DVM tach verified...
It being a solid hub or sprung has nothing to do with the quick engaugement. The fact that they don't have a marcel does. Sprung only reduces some shock placed on the driveline on enguagemant. The marcel on a stock disk is what makes the disk so easy to engauge.
No it won't cause you to run rich.
No these cars do not run "naturally rich"
Have you checked it with a wideband or measured the stock O2 voltage?
It is common to have 1 or more wires break just inside the O2 plug. It will run rich if that's the case.
