What does it take for Mid 12's?

Can it be done on the stock turbo?

My current mods:

3" DP/3" MP/3"Y/2.5" Dual/3" Straight mufflers
Intake/Cone Filter in cold air box
Boost gauge (lol)
S-AFC.
Solid engine mounts
Cheap-*** 10 year old goodyears, on stock wheels
Clutch that doesn't disengage properly when really hot


What else do I need to get there? I've got a fuel pump and injectors on the way.. then I need more fuel before I can get more boost..

I put crushed ice on the intercooler when at the track/whatever.. this seems to help alot. Do I need to go to a front mount/different IC?

OHHH

I've also got (on the way, not yet) open-vented wastegate.. so my exhaust flow should be pretty damn good, I think.. I don't think that my exhaust will be a restriction EVER again.. not with a stockport 13b-t.

I'm getting the twin-scroll working again this weekend as well, because not having it = teh poop. the low end is SO WAY BETTER with it on, not in performance driving, just in regular putzing around.

you will need a better turbo for mid 12's, and yes you will need a fmic

probably going to need around 320-350 hp for mid 12's stock turbo is only good for like 275

no weight reduction aside from easy stuff (hatch mat removal. spare, etc).

Better clutch is on the way when this one fails. not till then. I did it twice last year, and I'm not looking foreward to a 3rd time.


I guess I wasn't specific, but I want to be in the 12's with my 10AE

a divided wastegate isn't really necessary with my setup.. it's open vented and seperate from the rest of the exhaust flow.. it's "almost" divided.
