Rxp valve questions
I am putting a x charger on my 185 motor.. Was wondering if I need to change the valve, springs or retainers or if all. To be safe. Just a little info I have a 05 Rxp, bought with blown motor, had a full 185 running motor with 42hrs laying around. So I put it in.
this is what I plan on running this summer.
water box mod
straight pipe exhaust
4inch intake comming off sc
should I do valves, springs or just clips ??
any input would be great since I'm fairly new to building the 4tec
thanks in advance.

Your going to be dog shit rich with 48# injectors on a stock 215 ecu!
At stock rpm's.... you don't need to worry about the valves.

Only reason I was wondering about the valves is because I know the motors are famous for dropping the valves

That's not necessarily true. Some 04-05's had issues.... but that's about it. I blame the majority of those failures on improper winterizations, and the ski's sat for months allowing the exhaust valves to corrode.

There is no reason to upgrade valve spring/retainers if you choose to run the stock ECU with stock rev limiter, but if you plan to reflash with V-Tech and run higher RPM then the supertech spring/retainer kit is a great choice
