Hey guys i am having trouble deciding what oil pump

I am going to use the car as a Street / Drift / curcuit

has a 1.5mm oil restrictor in the block i am wanting to go to a 1.1 i think

Read all i can on the Nitto and Tomei pumps but i cant decide what one to pick??

My impression is both strong pumps. The Tomei's pressure can be adjusted externally when mounted. The Nitto's pressure can only be adjusted by springs.

The Tomei is also adjusted by springs/shims, externally.

I picked Tomei last week for pressure adjustment convenience, and they have also been around alot longer than the Nittos.

Correct me if I am wrong yet the Tomei item is not suited to bolt on application.

From my limited knowledge the Tomei is a higher flowing pump which would probably require more than a simple restrictor to head oil supply.

The JUN item is said to be really good and is also the choice of a close friend on here after some careful (and dubious) research. You may want to consider this item also yet try to stay as close to an OEM replacement item as possible unless you are going for specific goals and have a big build in the process.

Drift + added oil flow could be an issue, especially when all you are doing is banging in a piece that changes the ID of the oil pressure capillaries.

Just purchased a tomei pump. The new HKS pump is meant to have an even higher flow rate then the tomei pump, and also carries the pressure valve on the outside of the pump. Think it may cost the same as the tomei one too!

Good point mark, about adjusting oil pressure as the higher the pressure the better it is for the bearings and less chance of damaging your engine.

I know when I bought my nitto from jim @ crd he was telling the reason he has the option to lower the oil pressure is purely to make the other non believers happy...u need to cater for all customers.

Do yourself a favour, if u live in syd drop into crd and have a look at their nitto pump which is on display and has chewed pieces of an engine block via a massive failure AND the pump gear is still in 1 piece. Amazing stuff and hard to comprehend until u see with your own eyes.

Nitto is my choice :)

Something else I will also add, to advice from ppl in the know such as paul deimar @ red r racing!

For example, the nitto bottom end kit far exceeds the tomei bottom kit in terms of qaulity and tolerance straight off the shelf

      Cleaning my wheels 😍

      By The Bogan · Posted

      I clean my wheels every time I wash the car, I also clean the barrels, the only product I use on the wheels is truck wash and a pressure washer, followed by (inset your chosen name brand) wash and wax, time per wheel is probably 2 minutes total, cleaning the barrels is easy with one of these microfibre thingies on a stick from Sabco, they're also great for getting in between the front guards and body, and tight spots in the engine bay

      An updated post here. Sounds to me like there's definitely a bit of sketchiness here.  Old mate with 10 rusting Torana's in the front yard might be more who they're focussed on. (For right or wrong).

      Is this not just about people wrecking, and storing, multiple cars in their front yard? I now a tow truck driver that was contracted by the council to clean up housing commission front and rear yards in houses and unit car parks I'm all for working on, and doing maintenance on your car in your garage or driveway, but some people definitely take the piss  There's one house locally to me that I walk past regularly where the front yard and driveway looks like a wreckers, multiple cars in various stages of being stripped, and the yard looks like all of fluids are basically dumped on the ground I may be wrong, but it seems that the initial reports, which I've seen nothing actually official about yet, may be getting taken out of context, like alot of the latest "the sky is falling" stuff found on the youtubes for clicks

      have they? Link appreciated. I live in Casey. I can see both sides of the argument in this case. There's a lot of sketchy stuff going on. There needs to be a clear definition of what this is supposed to be IMO. I wager the intent was to be a broad sweeping brush against people who have 4 cars up on blocks on their front lawn, not someone who services their own car behind their own gate on a weekend bothering probably nobody. But it'd be hard to legislate the difference there.

      Oh, the wheels were already off. I wouldn't normally take them off to clean them although it does make it easier with the ceramic, so I might take them off when reapplying. I don't drive much but now with the ceramic coat, when I do drive and they get dirty I can get most off with the pressure washer. I'll be switching to dirtier pads soon which was the motivation for the ceramic as I usually just clean them and sometimes use Autoglym wheel protector. Nah, f**k the barrels! Haha, I'll give them a quick scrub when they're off the car and a pressure wash, but even I draw the line with the barrels. Yes, dark coloured wheels allow you to get away with a lot!
