Finally going na-t on my sc300. Will be running a T4 .68AR turbo for now. My main goal is to get it to run perfect on 7lbs of boost with stock 330cc injectors, stock ecu, stock fuel pump but with a safc while im saving up for an aem. How many of you guys went through this help a guy out??

 

Sounds like you want quick spool, for everyday drive-ability, The set up I was going for. Decide which turbo you want to go with. Look into Precision 6265.

 

there is no such thing as perfect with the stock ecu especially not with a safc.
look into my tt ecu mod.

 

Be patient, stock up all your parts, and save for the AEM before you install anything. This route should end with the best outcome.

edit: Clean looking ride by the way.

 

yup, if you are planning to do AEM, just wait for it - it'll save yourself all sorts of headaches...

 

I agree with everyone.. But at the same time this has been done over and over again.. the afc will give you the ability to tune in the right ball park but the stock Ecu will learn and fight the tune. but for temporary use it will do but, don't expect for your car to be a silver bullet lol it's going to have a little kick and a sexy bov sound.. That's basically it

 

A bit off topic, but what color is your car? I am getting ready to paint mine and I really like that light gunmetal color? Any info would be greatly appreciated.

Good luck with your build too, your car looks amazing!
Thanks,
Rick

 

Thanks Guys for the answers but i think i actually want to switch to ignition coils and 440cc injectors with the TT gte ecu. Does anyone know how well that runs on a auto SC? I know when done correctly on a na-t you basically got a smooth running single turbo mkiv setup.

 

Thanks its pearl gunmetal

 

it runs great on my 5 spd, there is a member doing it right now on an auto, and it is driving fine although his o/d light blinks. I think we just need to plug in a sensor/resistor to get rid of that so stay tuned you can get more info here
