also...I think this further supports my bad bearings in my diff theory:



That is my wastegate pull, from last November. both 4th gear pulls to around 110-115mph.

So I made whata I made with my SR20 turbo and stock tiny assed midpipe. Since dynoing I changed my midpipe to a catless, resonator less, 2.5" and I can tell you, I definately feel a difference in the way it spools and holds boost around 14psi now. So let's say that I maybe am making 230rwhp? If I changed the SR20 turbo to a GT2560 and ran 14psi, what kind of power do you think I would make? Would it be worth the hasstle of changing the turbo, and also the money I'd spend?

250 to a max of 260 if tuned right.

this was 14psi dropping to something like 10psi with the same turbo/kit on a '94 motor.




for any of those who care, my compression is still good despite my throttle sticking open like it did, however, I have lifter tick on startup now :(

Go make a thread about it.







In all seriousness, that's not bad given the WOT oil-burning mosquito-fogging that was going on.

You'd make over 265 @ 12psi with the manifold I have for sale cheap that's a bolt-in for your application and a good exhaust.
