Oil Control For My Rb

[badhairdave]

I agree with roy.

Ok so with all the responses so far it seems to be the best cost/benefit will be to;

1. Fit oil restirctors

2. Fit a large sump

3. Oil cooler

4. Really well thought out and designed catch can/sump breather setup

5. Leave the stock pump (can anyone confirm that the NEO does come with an N1 pump factory)?

6. Stock harmonic balancer

7 Drop it in

I would like to retain VCT, So i'll need to pick the sweet size restrictor. It seems to that 1 - 1.3mm is the around about size to go. But which size will be ideal. The car will get the very rare street drive. Obviously you dont want to starve the head of oil at these low rpm conditions.

I lost track of the number of track days i did with my old r32 with a std bottom end rb25 and the oil slightly over filled. I had a basic catch can setup but it did nothing really, never had oil in it at the end of a day.

Most oil control issues in rb20/25's are introduced when people start chucking high volume oil pumps on their engines. You were either 1 of the unlucky few, or possibly you just cooked the mineral oil...

What turbo are you going to run and what power, boost and revs do you think you will have?

If this is a temp engine, then I personally would just throw the std motor in, run a good oil cooler and filter. (pressures on my engine are all over the place depending on the oil filter I am running, Std Nissan seems to work well) and enjoy the thing.

Run Castrol 10W60 Edge, make sure your volume is a tad over filled and just enjoy the car. Unless you have slicks and running amazing times the engine will be fine.

All this money spent on your oil system, it would be cheaper to just buy another NEO IF the engine has a problem. In which case you woudl be able to sell the old head to the RB30 deviants, bottom end could be of use to somebody.

Seems waaaay too much hard work and money when rwd RBs last perfectly fine if you just keep good quality oil up to them.

Too much money? Restrictors $10. Bore out and relieve the oil returns $0

Well its not really $10 and $0.

Its more like $400 - $500 by the time you get a new FULL genuine gasket kit from the US. (I could use many of the other gaskets so i'd want a full kit).

Then the cost to have the head faced for a nice clean surface for the head.

New head bolts, some argue you dont need to replace them, I've reused them before, but for $70 and on a decent engine, why not use them.

You know what, I think I am wrong! I just went out and checked the oil pump off my Neo (which has never been rebuilt before now) and the oil pump definately looks like an N1 pump going by the pattern of screws on the back. I couldn't find my bloody big phillips screwdriver to get the screws out to check the gears inside though. I will confirm though.

PS cool video. I need to get my car build finished and get it out on the track!!!!

How sure are you of this, i have hear a few conflicting reports.

I'll be using a high flowed RB25 turbo with a 2871 cartridge. Power, hmm i would like to think it will make 250-260kW with injectors, AFM and a Nistune.

What will i rev it to? Hmm hard question, i do love revs, however, theres no point in revving it much past the engines peak power. Maybe a shift light might come in handy here to get those smooth shifts I'd expect peak power to be under 7,000 with stock cams.

Yes i see your point of just throw it in. However, a sump is just so appealing to me, it will have a decent resale value and help keep the oil where it is needed - near the pickup!

I'll be using semi slicks yes, when the car was last raced it did a 1.21 around Mallala on $120 Toyo RA1's that i bought from U pull It lol. I did manage to do a better time than several GTR drivers with relatively good setups through the day. How is this so, i dont know. But it felt awesome

Thats me, a little rough in many areas haha, but not too bad for a 2nd day out doing a sprint. That was skyline nationals last year.
