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

Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
