I've done a lot of searching to find the manufacturers of modified oil sumps for the RB26

so far I've found the Tomei baffle insert and oversized oil pan

http://www.tomei-p.co.jp/_2003web-catalogu...RB_oillube.html

also the Performance Metalcraft sump

the High Energy one (waiting confirm on RB26 pans, although their website does state they do RBxx)

http://highenergy.com.au/index.php?module=...me&content=home

then there is accusump

http://www.accusump.com/acc_products/acc_units.html

there is also the Greddy/Trust oil pan upgrade kit which is also an insert into the normal pan

are there any other companies in Aus that make custom sumps ?

Do many people use the sump baffles? Is this enough with the oil gallery restirictor, oil cooler, baffles and N1 oil pump to prevent oil starvation in most track/drag/street applications ?

Or should you spend the extra money and get an oversized sump and either N1 pump or Tomei or Trust oversized pump

regards

Jason

Hi Jason

It really comes down to what you plan to use the car for.

Personally I think track work is the hardest on the lubrication system as lateral forces are more likely to result in oil starvation than straight line acceleration (the pics on the Tomei website explain this well).

I went for the Performance Metalcraft option as it provided both additional capacity and baffling without hanging too low (I don't like how low the Trust sump extensions hang). Not a cheap option 'tho!

With regards to oil pumps - there is plenty of posts on the subject about what you need. I picked up a Trust pump at a good price, so that's what I use. I also use a restrictor in the block oil feed gallery.

An oil cooler is a good idea also if you do track work.

I'm sure there are plenty of other ideas and options, but this is the way I've gone.

Cheers

Gav

    • Thanks for the info GTSBoy, legend. If there is no downside i'll likely just get the larger bosch units because why not... I remember hearing stories about people washing their bores with fitment of too large injectors way back when, which i guess has made me shy about it now. But happy to know it shouldn't be an issue. Ozdavroz, the little rb20 is a lot of fun- now that i have a little extra funds and time i am very glad to be tampering with the ol girl again, after so long. More RB20's on the road the better. Cheers, Rowdy
    • ...just a note of warning, you shouldn't drive it about with the TCU in limp mode with only 3rd gear available ~ apart from the fact you end up sheering the ATF at the torque converter interface, the high clutch in these isn't especially the strongest, particularly bolted to the RB25DE mill...which is likely a 4AX01 box with lighter duty high clutch (the RB25DET got the bigger high clutch)...be careful out there...
    • Hoping to do similar mods to my RB20 once I get it running and reliable again
    • As you're looking at using a Link ECU, then large injectors are not a problem. But there's not really any need to go 1000s on an RB20 unless you're planning >>600HP on E85, which would seem unlikely. There are other options for injectors. The Xspurt ones are available from a number of places and you can get them in the mid 600s and 725cc, which is probably a sensible place to be. These are all EV14 based. If you are not using the stock AFM (at all, which would be the case with a Link) then a large turbo intake pipe to suit the ATR turbos is not an obstacle, so you should use one instead of a highflow. Results will be better.
    • Hey guys,  I'm after some advice and this here is the best place to get it imo. I was a member a looong time ago under another account, with a lost email address. Its nice to jump back on and see some of the same names still giving good advice.  I mothballed my car when i moved to perth in 2013, and after getting towed across the nullabor a few times it has officially done more km's on a trailer than under its own power. Now that i have started the process of tidying up and modifying it, i see the fruit available (and the fruiterers selling the produce) is different than back in the day. hence my questions, as i used to 'know' what to get and now, i'm not so sure. Engine wise the car (92 gtst) has a walbro 255, k+n, fmic, cam gears and and turbo back 3"exhaust. Wish list is a Hypergear high flow or ATR43G1, Link G4x and some newer injectors before a tune up. My goals are modest, only low 200's power wise. i know i could achieve this with less, but i've been swapping out old for new where i can. Every cooling hose has been replaced, along with mani gaskets, WP, thermostat and radiator, fuel pump and timing belt, tensioner and idler, and i rebuilt the steering rack. Regarding the injectors, the fruiterers all seem to sell what used to be considered quite large injectors. There are a lot of options for bosch 1000cc EV14's, and i would like to know if that is a suitable choice for my build. Is modern injector design good enough to run these at the low duty cycles that i likely would be? is there a downside to running a too large injector these days? or, would there be an upside to running a smaller injector at higher duty cycle? I can see that there are smaller injectors still available, but the ones i have seen specifically marketed for RB's are pretty large (see: https://golebysparts.au/collections/fuel-rail-injector-kits/products/nissan-rb20-fuel-rail-bosch-980cc-1150cc-injectors-turbosmart-fpr800-regulator-kit), and i dont know enough about them to say one not marketed for RB's would fit or not. I have searched the forums, and amongst all the posts on older tech, I did see gtsboy recommend EV14's, but no size was mentioned... again, i'm not clear on if the smaller size bosch injectors are also EV14's as they do look similar.  also, if someone can recommend a tuner familiar with RB's in the Geelong or West Melbourne area i'd appreciate it. Thanks in advance guys. Cheers, Rowdy
