Hey all.

Looking at new sump for my 25/30. Its going into an R31. Will i have any clearance issues with swaybar/crossmember and the like if i get one of these enlargened sumps.

Are the RB30 sumps the same for both the VL and R31 RB30's?

Thanks for any assistance,

Chris

High Energy make their RB30 sumps to fit into skylines. The old design would have clashed with the swaybar in a skyline (have one at the workshop, was off my RB30 when it was in my mates commodore), I measured up my mates one and rang High Energy to begin explaining what I needed (a 50mm 45deg chamfer off the leading edge of the extension) and he was like "oh, we already do that now for all RB25 and RB30 sumps".

I will be getting a pro-circuit High Energy sump, was meant to already be got but decided to get some Spool rods and needed to get a 6boost manifold :)

Edit: can't see anything about baffles & gates in that JPC sump..

I'll have a look closer at all of the above. I did notice that the Lewis Engine's one doesnt make any references to additional baffling and the like.

Thanks for that gents.

I've decided to bite the bullet and get the ASR sump. Spent too much money already, whats a few more dollars lol.

For those interested, apparenlty the sump will still fit a 31 all right - incase anyone else is doing the same sorta thing.

Cheers for the tips lads

Just Jap sell the ASR sumps.

I emailed Lewis Engines about their sump, they didnt show any photos, but they claim their sump sump is a proven design which has been fitted to hundreds of track, and drag cars. They also offer another sump for $699 designed for even heavier cornering, acceleration and braking.

Got any pics of the "hardcore" one?

I fitted an ASR sump to one of our commodore cup engines yesterday and they are a work of art. Just make sure you pull out the screen and wash it out properly as there will still be some metal dust and shavings from the fabrication. All the parts are laser cut and well finished and the welding is perfect. This sump was $1300 but you can see the dollars in it. I can't imagine something less intricate costing anywhere near that. though.

I have a mate currently making an RB30 one for me, I'll snap some photos when it's done. We're going to have the pans and baffles laser cut and cnc bent once we have the prototype done.

Sweet as. I like pictures lol

No it doesn't, at least in my R32 GTSt the standard RB30 sump doesn't hit the swaybar.

It is the extended sumps that might have problems but High Energy now take into account the swaybar in skylines for all their RB25 & RB30 sumps.

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
