by proper do u mean legal way or proper way for not having any crankcase vapour going back into your engine? proper legal way is to have it entering your catch can through on of the top outlets then back into before the turbo for the outher outlet. and the drain at the bottom should feed back to your sump so u don't have to ever worry about it getting full..

um.. sure? lol.. well i dont mind if its not hooked up2 the sump.. the rest sounds ok tho.. :banana: def want it the best way.. i find it hard for a pic for an rb20 :D( its connecting up to a d1 catch can.. has 2 dash fittings at the top.. and a drain plug(currently closed off) ..

haven't got a pic of one for an rb20 but if u dont want any going back into your engine which is best for performance then u need to block off the one going to your inlet manifold first of all otherwise you'll get an air leak and won't run properly. then either drill some holes in the top of the catch can and feed the 2 outlets from your rocker covers into the 2 fittings. or somehow join the 2 outlets on the rocker cover so that they end up into one of the fittings on the catch can then stick a filter onto the other catch can fitting... hope this helps..

haha aww sowie brother.. but u have an rb25 it just sliped my mind.. mine 100% plumbed back.. an legal ftw.. anyways heres a pic.. i made everything from scratch.. bought it all from bunnings rofl.. catch can made out of pvc sleeve and fittings ect.. baffled and stuffed with scourers ect.. and the hose.. and Hose clamps.. WOO sexy time.. mite go a 16mm hose dia.. an fittings wen i end up with a good lookin catch can ect :P

im about to install mine. yours looks nice and neat. but where did the second hose go?

or you only had 1 inlet/outlet

It goes to the return on the intake pipe.

Probably better to set it up the other way... as far as i can gather anyway :S

    • Don't take it as a guarantee. It's all a game of statistics. And on top of that, smooth over a thick layer of "quality of spanner spinning" as a further Gaussian curve of probability of failure. You play games at anything above ~400 HP, and you're using up margins in terms of engineering and luck.
    • Aye, everything is being touched and all the parts that are responsible for the oiling issues are also fixed. (Crank collar, billet prp oil pump, head return to sump, yada yada yada)  Everything used is of reputable brands like greddy, prp etc. My tuner did mention we’d keep the torque on the “lower” side.   glad to read that my engine won’t blow up on me lmao 
    • It's a fuel pump. EFI, high pressure, but specs otherwise unknown. A bodge job.
    • 800 engine horsies is fine. Will need all the obvious upgrades. Rods, pistons, oil pump, big sump, sump breathing mods. Build for revs because revs are power with less stress on the bottom end compared to boost. Keep the torque down in the midrange, either by limiting boost or timing.  
    • Hiya guys,    i’m currently in the process of getting my rb26 built. everything is being replaced with better/upgraded parts or oem when that’s good enough (which isn’t alot lol). someone earlier mentioned to me that i’ll be screwed cause the iron block can’t take 800hp (to the engine, not wheels) which is what it’s being built for.  what do you guys think about this, am I cooked or na? The guy building the engine will also do the mapping as he is “the guru of old nissan engines” here in Belgium. I know the mapping makes a huge deal so i’m not concerned about that.    I honestly he’s talking shit cause he’s that kinda guy but a second opinion never hurt anyone! cheers in advance! 🫶🏻
