hey guys ive done a search and found heaps of info on dead n1 pumps and using jun/tomei pumps etc but im just interested at what power levels would i need to upgrade the stock gtr oil pump? i know the n1 pump is worth bugger all but they are like russian roulette and im doing a budget build if i can as its a spare engine, im gonna try and avoid having to upgrade the pump if i can.

so what power levels can i safely run with a stock gtr pump on a rb26? and if i went for a 26 head with rb30 bottom end would i be able to make more power with the gtr oil pump safely? how much with the 30?

sorry if this has been asked before, any links to relevant threads appreciated, or any info on the subject even better :thumbsup:

RB26 Stock pumps are good..if new...up to 330kwsATW

N1 pumps are only a little bit better..though some say they shit themself above 370kwsATW.

The figures above are only estimates....type of driving you do,frequency of oil changes and conditions

play a big role in longevity of these two pumps.

Jun,Tomie and other oil pumps are made tough to handle above these figures reliably...but also cost 3 times the price.

      We have a huge update coming in the next few months, version 5 of Invision will be released. I'm holding off any changes until after this change as I'm not sure what features will be removed or introduced.

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
