the install wasn't that bad. i took my time so i didn't mess up anything. some of the bolts are pretty difficult to get at though. an impact gun would almost be a must for some of the big bolts on the turbo. you have to pull the radiator out too, unless you want to put a hole in it. for some odd reason more coolant came out then what went back in. I'm not sure if i got an air bubble or what. I'm new to the forum and i'm curious about flashing my ecu, but i'm curious what these guys(tuners) are doing to get 25-45hp.

 

there is a way to discon the ecu without discon battery... you can unplug two fuses in the fuse box thing near the driver'se left leg i think... dunno tho... would have to check.

 

there is another way to reset ecu completly,
disconect both pos and neg and touch each other.!

 

where can i get 1o.5 hotside. and is this stock turbo upgrade?
what is hotside exactly./?

 

^this is a stock turbo upgrade...you can get the 10.5T turbine housing from

forcedperformance.net

Another nice stock turbo upgrade is the Titanium-Aluminum (Ti-Al) Center House Rotating Assembly (CHRA). Having Ti-Al CHRA should offset the lag felt by a bigger turbine housing. I've seen them sell on ebay for ~$400.

 

It needs to be tuned. Even if you reset the ecu, everything is still adjusted according to base trims which are not altered when you reset it. This means the ecu can only compensate for so much without a reflash. Get it tuned and you'll love it. I promise.

 

where can i get a reliable flash? I live in washington.

 

If you can go without your car for a few days, most tuners have a mail-in flash available. If not, you may have to wait until someone travels close to where you live. You could check around to see if anyone can do it locally as well.

 

The increase in lag is normal as the larger nozzels require more exhaust gas flow to develop the same pressure. The lower pressure will not spin the paddle as hard so boost will not occur as early in the rpm range. The ti shaft has less mass so it will spool with less pressure. If you combine the two upgrades, for around $600 you will be making some very nice broad band gains from a stock looking turbo. The potential benifits to be gained from adjusting the ecu maps will not occur by mearly letting the ecu learn.

 

no its the fuse box in the engine bay,just pop the cover off and look for the key on the underside of the cover that has the pictures of the engine and remove those
