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.

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. -------------------- QUOTE(lagos @ Jul 10, 2006 - 1:55 PM) [snapback]454118[/snapback] 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. |

Wolfkatz sounds good to me, but out of curiousity why wouldnt u buy an ATS rail Jay? bboy -------------------- ..(formerly daily driven) 3S-GTE powered celica currently set @ 12psi.. |

Boring out the rail, even a little bit, would concern me due to structural integrity. Now, I have never heard of a problem with an ATS rail so I don't want to imply that the structural integrity is weakened to a point that they are not safe or that they don't do their job in lowering the pressure drop. I am just saying that I wouldn't buy one. -------------------- QUOTE(lagos @ Jul 10, 2006 - 1:55 PM) [snapback]454118[/snapback] 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. |
