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-ass 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

gsracer 08-29-04 07:42 PM

300rwhp with drag radials/slicks will be close.

front mount/slicks and good driving.

87 turbo II with a turbo back racing beat exsaust, bosh fule pump, 10mm plug wires and nkg plugs, permacool e-fan, hks BOV, racing beat springs with tokiko shocks, and a new 13b from atkins with a full street port and 3mm apex seals, apexi intake, hks ground kit with 8 in wide volk gt0u rims get me to 12.9 at 105mph...

High compression turbo-NA @ 12PSI and a good launch...

woooo hooo....I already have the N/A! Now all I need is to invest in a $3000 - $5000 turbo setup :(

How about to you take the TII motor out and drop it into a gutted 1st gen. I guarantee you will see 12's.

BNR Stage 4?

andrew lohaus 08-30-04 04:07 PM

a better clutch and tires are gona be a start.

LookThatsMe 08-30-04 04:51 PM

def need a better clutch, flywheel, fmic, some stif shocks so u dont do wheel hoops, better turbos, get a external wastegate with a purge guarantee it will turn heads, and port out your intake manifold, and get some wide wheels with tires that have crazy glue on them lol

LookThatsMe 08-30-04 04:52 PM

and dont forget some weight reductions

Terrh 08-30-04 07:44 PM

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 :)

Terrh 08-30-04 07:46 PM

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.
