Thread: Reliability Upgrades
12-18-2013, 08:09 PM #1
I'm doing some work on the RXP mainly for longevity and reliability any other suggestions to add to the lists ?
The supercharger was done by Jerry about 20hrs ago with the latest Seadoo kit.
- Upgrade intake and exhaust valves to Supertech.
- New valve seals.
- New rocker shaft bolts.
- Flywheel bolts.
- 08 S/C oiler mod.
- Check pump bearing and add gear oil.
- Bilge pump.
- New in tank fuel filters.

that's a good start... new battery and starter solenoid wouldn't hurt either

Looks like you've got the known problem areas covered in your upgrades.

Looks good, might consider a set of arp head bolts, nothing wrong with oems but you can reuse Arp.
OEM head gasket also.
Maybe a new carbon seal, hat, and bellows if yours are original.

I have an oem head gasket on the way.
Carbon seal and bellows were replaced in July right after I bought the machine.
The manual says the head bolts can be reused as long as the length is within spec, mine are all 1mm less than spec. I planned on re using the head bolts unless there is a really good reason not to.

The manual does say you can re-use them as long as their within specs..... but I personally wouldn't risk it. If they don't hold.... your doing the entire job over again, and buying another $80+ head gasket. I'm not a fan of the oem head bolts, I'd recommend you buy a set of ARP's.... and be done with them for good.

I have to stop hanging out here you guys can spend my money faster than my wife and three daughters
OK I'll look into the ARP stud kit !

True you can reuse the TTY bolts if they measure within spec and have not necked down, many do, including well known performance shops. I don't really like using TTY bolts, don't like the install process, and my understanding is that one reason they are used is to compensate for minor install variants when being installed on an assembly line (Minor install variance will still yield the same clamping force?). Just personnel preference for me and I agree with others I would go with some ARP head studs especially if your already in there, and you intend on doing future performance mods?
surely you could pick up some retainers to go in with the new valves while they are being done? Pick up an ECU later and turn some higher rpm?
are you still running the stock mani intercooler? External IC would be more efficient and cooler IAT's can only be a good thing for the motor.
