    rxtx260 supercharger & injecters

    i am currently in the process of rebuilding my supercharger, my querstion is, what injectors come stock with the 260tx, and what would be the most reliable way to boost the ski? im not looking to spend thousands and thousands. i have a 8650rpm reflash, exhaust, intake, and the new updated oem I/C. what are some good options to boost up the ski and what other supporting mods do i need? thanks.

    I've been reading up on posts for about the et127 on a 215, would that be a good option for a 260?

    The stock charger on the 260 has a 137mm wheel. The ET 137 +3mm has been discontinued so you will go with the ET 137 +4mm as an upgrade. http://www.4-tecperformance.com/inde...oducts_id=2017

    that would be going backwards. This is the upgrade you will want to use

    If you're running stock valve springs you are in the danger zone at anything above 8300 rpm.

    Why do you need to run the fuel regulator?

    id upgrade the valve-train and throw the ET 137x4 on it along with a 4in intake/velocity stack set up......all you'd hear is blower lol. id be curious to see what your DCs are at but u might need a regulator or bigger injectors.
