Do i get my stock ECU or CPU or w.e Reflashed or tuned to handle my turbo on a 420A engine? OR do I get a ecu cpu out of a GS-T?

Umm no.. You dont need to mess with ur stock ECU wen u turbo. I turboed my RS and its a straight up bolt on with a lil Fab work. If u plan to get EMS like a full stand alone then YES thats the time you'll mess with ur ECU. If you have big cash and the patients to turbo our motors then Go For iT!! Just have a back up plan in case things go wrong in the future. Be ready to drop like 15g for our motors. Im already up to 7g just for the turbo kit and other parts. LOL thats not counting my rebuild in Jan. thats another 7g!!! HAHAHAHAH. like i said BE READY! :imsorry:

Don't scare the poor guy.j/k

He was right though. It takes a good amount of money to boost a 420a, but its worth it. You should get a synapses missing link for your map sensor or YOU WILL GET FUEL CUT AND BLOW UP YOUR BAD **** 420A :57:

wut kind of fab work you talkin?? so the innercooler pies can fit or what?

um no the intercooler is a straight up bolt on.. the fab work is welding the oil return line in the oil pan, custom dp, BOV flange in the piping. etc..

Maybe 2 times out of 10.

hmmm... instinct tells me its not a bolt on...

well i got the Hahn $1000 intercooler up to 700hp that bolts right on with the pipings

sounds good to me

You should have to do some minor modifications to the front bumper. I had to remove my foglights to accomidate the piping. :57:

if i went turbo on my RS I would proly have to cyt away on the inside of my bodykit huh??? Unless the pipe goes under the front bumper bar

Hahn is the only one i hear bolts up perfectly.

The hahn kit is as close to a bolt on kit as your going to get. :57:
