Hello !

I'm trying to find a definitive answer on this ; do you absolutely needs a sump extension when fitting a hi-flow aftermarket oil pump ? I was told because of the extra pumping power these pumps have, you should have a bigger sump as well because theres a risk of sucking dry the sump. your though ?

Thanks!

For the cost of a sump extension eg trust it's worth it. To change the oil pump it's an engine out job with the removal of the sump. For me it's a no brainer.

I know I didn't really answer your question. But do it right the first time and don't worry about it again :)

I'm assuming your talking about an rb26.

Yeah, sorry for not answering your question.

What you have been told is correct especially if you intend to track at some stage.

Yes if your oil pump is pumping at a higher rate than OEM there is a good risk it will empty your sump.

Do it anyway.

My engine will already be out, this is not a problem.

the problem is that I drive my car in the street and here in canada, we have tons of pothole, so the fact that I already ',scrub my pan at the moment, with an even lower sump/pan..i'm really scared to crack my pan/sump.

I barely track the car and have a tomei baffle plate installed in the pan. So I think my best choice is N1 with reimax gear.

Get a decent sump made. Forget that trust 44 gallon drum junk.

I have a 9.5 litre sump and it's not the lowest point up the front of the car. Maybe contact rips in NZ and get him to make you one.

thank you sir. I will see what these guys can do or any other custom sump in fact. Pretty much, the last piece of my puzzle before we start building :)

The danger of emptying your sump is real. You should probably fit restrictors in the oil supply as a minimum but an enlarged capacity sump is a really good idea.

Someone in the US has recently imported a couple from Racefab so maybe worth a look if you have time for shipping:

How low does the Trust one sit?

Although it might be at risk, a deeper sump is a better design than something that just has more volume by being wider on each side.

I'll give you a definitive answer, that is tested and proven time and time again.

1. Yes it is essential to fit a bigger and baffled sump

2. Call hi octane and get one of their cast sumps (assuming we're talking RB26) and be done with it.

Although I have recommended a bigger sump it is NOT in fact essential. I have just reread your post where you say you hardly track the car. I do take my RB30 with an N1 pump to the track and I have a stock RB26 sump with Tomei baffle kit. I also have 2 x 1.00mm restrictors and a good sump ventilation system. It has been fine for three or more years now.

But if you do want an enlarged sump there is no reason why deeper is better - with a good system of gates it is only capacity that matters. Have a look at some of the sumps on Rips engines:

A deeper narrower sump is improved as the oil is always closer to the pickup like the Trust design. If it is gated and much larger, wider, etc then of course that is better again.

More oil capacity is always better, more cooling effect and less risk of starvation with higher flowing oil pumps.

Have a look at the RIPS sumps, they don't sit any/much less lower than the stock sump really. And yeah as mentioned, avoid the Trust ones, they hang low.

This is the one i am talking about. Ends up holding about 8 litres.

You can also pick them up through Performance Metalcraft.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
