Spoke to my tuner about this today, one of the highest rated garages in europe. Was told for my power won't need a restrictor or a rear head drain. The stock front drain on the 25 was said to be enough. He did however advise a n1 due to the extra mass of oil moved. As the car won't see prolonged high revs i think it should be ok on the head pooling issue.

Imo you treat the n1 pump as a stock one, after all its only a reworked stock unit. Im becoming of the opinion other supporting mods are required to make the most of a n. Making them quite a lot more money for something I probably won't see benefit from

Morning guys, thanks for the input. Ok I will look into getting oil restrictors and a baffled sump. How would i go about making a drain back to sump from my catch can? I wasn't going to bother with bearings and piston rings, or drilling out the block oil returns tbh as that means fully stripping apart the block. I know if I had the pistons and rods out I wouldn't be able to help myself but forge them, then the engine would never get in the car! So consensus down there is n1 pumps aren't worth the bother?

Thanks for the reply. The engine is out now head is off, thats my prediciment. I dont want to blow it up tbh as there fairly expensive engines over here, (I'm from the UK) or mabie im just tight. Is it worth spending the money for extra insurance or will I just cause myself un necessary headaches for no real benefit? If I just got a new stock pump and no fancy drain kits and what have you I could put the money toward cams or a better ecu ect. I want the engine to be reliable, that's the main thing. I don't want it to go bang in three months or so.

Hi guys just thinking about oiling for my engine. Im hoping to run about 400-450bhp on stock pistons/rods. Car will be street driven with the odd drift/track day and a sensible rev limit, not thrashed off the limiter. What would you all do in terms of oil pump/ oil restictor/ head drain kit? Baffled sump? I was thinking a n1 pump, are they necissary? Any advice welcome.

Thanks guys! Dont worry im not a noob to forums, i know how annoying it is having the same questions asked over and over. Yes some do say it ruins the handling of the car, some say they prefer it. But that's a whole kettle of fish I don't plan on opening! As long as its quick enough to scare the crap out of me il be a happy camper.

Hi guys, this is james, 200sx (silvia) owner from the UK. Got a rb25det to fit in the car and came here for some advice as this forum seems very knowledgable. Please look out for some threads with stupid questions, i want to spruce up the engine a bit before it goes in the car. All the best from sunny England!
