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.

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
