Tomei oil pump users

[hozer]

I'm not willing to run a trust extension. I used to work
At a performance shop and a car came in that had one which went over the ripple strip and into the sand and had ripped his sump extension off. There went his hks 2.8 engine.

If I was to get an extension at all it would be a hi-octane racing sump. Which follows the same design as the winfield r32 that took out Bathurst giving the gtr it's name Godzilla. These sumps go for a little over 2k aud. considering I paid 1400aud for my pump this is why I'm making sure it will be completely required.

RIPS extension sits 3mm lower than the OEM pan and will cost you about $500. If you can rip that off you have other problems as well methinks. And a +1 to what Dragon said.

Regardless I do think you'll be fine with no extension... Just a good idea

No one has really gave me any hard evidence/personal experiences with running a Tomei pump with no extension.

My current oil control mods are:
1.5mm Tomei oil restrictor
Tomei sump baffle kit
Mines cam baffles
Nismo oil catch can
Tomei Oil pump
No mods C/O to the oil return side of things

In my eyes id say it should be ok so long as I over fill the oil by about a litre. But some good personal experience would be good to just back up my assumption.

On my car it's filled to H mark.

From what I understand, sump extension works with a longer pickup, so pickup is always emerged in oil (doesn't uncover and starve engine, etc of oil). If Tomei oilpump is moving alot of oil to head and starving sump of oil, that would be a worthwhile mod.

Another option is run a Accusump tank, as oilpressure does drop on high G corners on racetrack (even with baffle plates, swinging pickup as used on N1 GTR racecars, etc) and helps to solve the oilpressure drop problem (without fitting dry sump) -

Also Accusump helps with prelubing engine before start up which reduces wear on turbo bearings, engine bearings. Some use Accusump on track driven V8's due to using shallow sumps and is commonly used on RB26, RB30 engines.

Accusump tank is used on Borg R33GTR which R.I.P.S built (blue tank above intercooler) -

I just bought the pump cause it hasnt been known to fail as often as others... maybe i hadnt done a lot of research back then and i didnt know as much then as do now but i went with the best pump i could afford cause alot of people said it was the best... plus every single person talks about the oiling issues of the RB26 so people rebuilding look towards every possible thing that can be done to increase oil flow back to the pan (and to everywhere else) and decrease starvation and oil gears cracking etc etc... just putting that out there cause i wanted to overdo everything to do with oiling just because i maybe hadnt done the research... since i dont track my car as of yet i may have saved ALOT of money going other routes... but i dont regret my overdoing it...

You have a huge budget. You better get a bigger oil sump friend, why skimp out on that when everything else is badass. If anything, your fueling and oiling should be the best! Shoulda gone in on the Drysump group buy... (perterson fluids)

Just to give you an insight of my actual build. I already have a Tomei oil pump fitted to my engine, with a Tomei sump bafflie kit and head restrictor already fitted. Tomei actually recommend using the baffle kit for street applications, and an extension for track use.

I would like to back this statement with some experience from people who are running the pump with no extension for street use

$500? If you're talking about the RIPS oversized sump, they're like $1000 if you get a bro deal from a preffered distributor. Who the heck do you know?


Markdett, you can't tell me your project is a street only machine, the thing is NUTS! You'd be wasting so much money if you weren't ever gonna track it hard lol. The thing is pretty heavily modded.

Yeah street use only, we only have one track here in perth, and its about an hour or so drive. Compared to some of the track builds we used to do, this is pretty mild. stage 1 if that.

Also in regards to the rips sump. Was quoted about 1400 welded!

[gtrjon]

Thats not that far off the trust route. I paid 425 for my trust sump + another 400 to have it cleaned,prepped, and welded

[markdett]

Think I might just commit to the Hi-octane sump. Probly one of the best designs ive seen.

For your veiwing pleasure,

I'm really liking the accusump , anyone here got one ? looks like a better alternative to welding the oil pan with an extension .

Check out my dry sump set up , which is based on Aviaid Series 2 pump. It is comparable to the Hi-Octan kit, if not better, but won't cost more than Tomei Pump + Hi-octane sump.

the hi octane dry sump system costs some $7000 with about $5500 worth of Peterson Fluid parts.'

As for the Accusump, I agree. I use one WITH my Rips sump to make up for the fact that my dumbass shoulda gone drysump with my budget.

As for quality and cost, like everything they build, RIPS>Hi octane.

From 4:35+ R.I.P.S talks about the process you have to follow with Accusump before starting, switching off engine -

The peterson pump 4 stage is about $1300, The tank is about $700. Whth other small things like Mandrel, Drive Gears, etc, I'd say there is about $2300 worth of peterson parts. Plus another $1000 of other things like OE Oil Pan, Greddy Oil Adapter etc, at most, there is $3300 of parts in total. The majority that you pay is for R&D and Labor.
