are you going to pull the engine appart? you will need to take the crank out and get a machine shop to machine the snout down so the collar will fit.

For drifting its a must. hitting rev limiter all the time will jerk the pump and eventually crack it and stuff your engine (i have yet to see it though)

About $250-300 fitted, its cheap insurance, id put a 33 or n1 pump at the same time.

Theres a person on here who had this exact thing happen. Rev limiter launches, and all the shock loading shattered the N1 oil pump drive. (they are made stronger, and more brittle, theres a fair bit of talk about it on this forum)

As for limiter action on a stock oil pump... I think its definitely worth extra coin.

To not fix the crank issue, is madness. Simple as that.

i decided to use the stock nissan rb25 oil pump on my rb30det with the crank collar mod and have had no issues at all!
