A few ?'s
A few ?'s
Ok I have a PMTR setup right now. I'm running Spoon JDM ITR pistons, CTR cams and ITR OVS with PP IVS and Ti Ret, Sk2 IM, P28 chip ECU VAFC, stock GSR Injectors and Fuel Pump, B&M Reg set at 43 and I'm still playing with the fuel engagement with the VAFC. Now I would like to go with a set of Sk2 St2 but would I have to change my valve train again just to run the SK2’s? Also I was planning on changeing my injectors and fuel pump, I have it narrowed down to a Walbro 190 or 255 and RC 310’s. But I don’t know if I should get the 255 pump, any feedback would be great.
Go with the 255 fuel pump and go with a set of 370cc not 310cc, with 310cc your injector duty cycle will be a little on the high side and if you ever decide to push your compression up a little in order to get those cams to make power, you'll need the extra fuel. Besides, it's never bad to have a little too much rather than too little. But yes, you will need to change out your valve train, amongst a couple other things in order to run the stage 2 cams.
Good luck,
