So I’ve been thinking of swapping my rb25 out for a 1j. Now my reason for this being is the reliability and a future rebuild if the internals go. (Looking at it from a future financial point too.) main goal of car is to be street/drift track car.

Power goals are 450whp max. I know for the rb25s stock internals thats as far as you want to take it. That’s fine but now comes the other issue; oil control.

Tackling the issue:

- Aftermarket oil pump and or oem pump with billet/steel gears.

- Head oil drain kit to the sump.

- Porting oil return holes.

- Bigger sump.

Then later on forge it out.

What are your guys opinion on this? Should I consider going the 1j route ?
