The Skyline Guy r34

I see that the oem bnr34 crank pulley is pretty affordable at 180usd and the fluidampr is over 600usd. Would a new oem pulley be a good buy for the internals?

Ok, so you would say its worth getting a damper?

Ok, will it be worth it to put on a fluidampr to prolong the life of the stock pump and gears?

I dont have the space or time to pull the engine unfortunately.. Ok so ill wait with the pump and gears. Would it be increasing the life of the pump/gears and worth the $ to just put a fluidampr on there while changing the timing belt which needs replacing soon anyway?

Im not pulling the engine for an oil pump, that is too excessive. I'll try to do it with the engine in the car, taking off the gearbox and sump. I've also got the oem clutch so maybe I should upgrade that while in there. Im not sure what type of rev limiter it is.. Didnt know there were different types of rev limiters? As for my driving, its only on the street doing a few pulls through the gears to about 7000rpm. Maybe a few launches if I feel like it. I also have a antilag/launch control button wich I know hammer alot on the gears.

Yes the engine is in the car and running without issues. The car is tuned with all of these issues in mind and is limitet to about 7200rpm. But I was thinking it would not hurt to have 25 year old gears swapped to new billet ones? Also putting on a fluidampr would help ease the stress of the pump?

Ok, so let me clarify.. This is a street car that does about 2000km a year. I know a complete billet oil pump is stronger and better but I just cant justify going down the rabit hole (atleast not right now) I have a link ecu that tells me I lose preassure at one pull, because the sump runs dry. I now have about 6,2 liters of oil in oem pan and that fixed the problem. Putting a nitto pump or something will surely drain the sump quicker and ill need a bigger sump and so it begins... I just dont want my oem gears to fail. Surely some billet/chromoly gears will last longer if I center the gears correctly? I also found the reimax gears with a billet backing plate for not too much more $. Is this plate worth getting along with the gears?

Combined with a fluidamper this should be a pretty safe engine?

I have a 500hp r34 gtr and I guess its time to upgrade the oil pump gears to something stronger that can handle rev limiter and shock. I've been looking for billet gears and came over the plazmaman gears for about $380, but then I saw Reimax had some Chromoly steel gears for about $250 parts number: 15110-AAR11-81. How is the strenght on these? Anyone heard about these shattering? Is chromoly steel as strong as billet? I have the oem 05u oil pump so the 81mm should fit?
