Does anyone know how much boost (MAXIMUM) a non-modified CT26 turbo can handle???

A new rail is necessary on TUNED engines. If you are running the stock ECU, the leanest cylinder on the stock rail is still pig rich.

I asked a similar question in their original thread a long time ago and the Wolfkatz's could not say there would be a problem on the stock rail and ECU even with an upgraded pump. Check out posts 87 and 88 in this thread:

Fuel Rail Thread

I have yet to see someone having a problem at 15psi on stock injectors, stock rail, and upgraded pump.

i know your trying to do the right thing for your motor, but this is one of those times where you should just trust the guys who have had their swaps for a while and have done a ton of research into this.

thnx jay...yah i was thinking myself "why would it be leaning?" when the ecu dumps a crackload of fuel after 12psi to prevent detonation. im not doubting theres a pressure drop...but i dont believe this will lean anything out to dangerous levels. still tho...75 bucks is still pretty cheap for an upgraded rail from ATS

Its your money. If it were me, I would wait until you get an EMS and then buy a real rail from either Wolfkatz, Hux Racing, or Speed-Source. I like ATS and they provide very good products but I would never buy one of those rails.
