Official Turbo LSJ thread!!!

Orginally i used the gm gasket and put rtv ultra copper on "all exhaust components" as per zzp instructions. Lasted 2 years and then got the annoy exhaust tick on start up, ***** like nails on a chalkboard to me. This time around I cleaned everything off and I'm not using anything but new gaskets. That grey stuff on the top of the manifold is propoxy20, like jb weld but better and actually withstood the heat of the manifold without smelling like **** for days. Helped me track down where the leak was coming from.

S256 will make more torque, especially on 6 more lbs of boost and more timing. I'll need to turn up a bit to see my torque curve start to look like that. Also, as you go up in turbo sizes, you will fall farther and farther away from a 1:1 hp to tq ratio. My turbo is just coming into its efficiency range, as the graph shows, BUT I will finally be able to let her eat a little this week

I used an ebay kit i think was for a mustang and it fits pretty well actually. Only had to hack up one pipe. You probably dont want 3" piping though.

OMG the sound of the s259 batmo compared to the s252 et. Made me fall in love with my car all over again. Going to try to get some vids if weather is good. I can't wait to start turning the boost back up.

Not even close. No need to be accusatory.
Just simply saying anyone can say whatever they want. Without proof, who cares? I'm not at all saying it didn't happen. In fact I'm certain it did. We were talking about the cars out there now.
Kenny broke 12's but doesn't have the slip, so few people believe it, and no one really cares.
Innocent until proven guilty
False until proven true
Wrong until proven right

I meant to say broke past 12. Either way, I wasn't at all saying it didn't happen. I was just using it as an example of if you don't have proof, most people aren't going to believe you. It's sadly just how this world works.
