Steve Cargill Posted August 3, 2002 Share Posted August 3, 2002 From what I've picked up the following is roughly true. This is without boost controller, fuel computers or ECU changes. J spec pump & injectors are OK up to about 18PSI (along with the J spec turbos) With hybrids they are only OK to about 15PSI If I put UK 550's and resistor on with J spec turbos there is no benefit and I'm over-fuelling. The fuel pump may also be borderline for this flow. 550's with UK pump on hybrids should be OK for 18PSI Done a bit of trawling and come up with the following parts list for the upgrade. Any other biits needed, pipes clips etc etc. Injector 6* 23209-49035 Resistor 1* 28510-46020 Fuel pump 1* 23221-46110 Link to comment Share on other sites More sharing options...
Ian C Posted August 3, 2002 Share Posted August 3, 2002 You can run 21psi on hybrids with that setup You need wiring from the engine loom to the resistor pack as well. 7-core automotive stuff. There is a 7.5mb download here Injector upgrade That is my documentation of the installation process, if you are interested. -Ian Link to comment Share on other sites More sharing options...
