[vspec_gtr32]

looking for an oil pump for my r32 GT-R, undecieded on which brand, i was looking at either a Tomei, Jun or Greddy one, they all look as good as each other, i'm sure people have had good and band experiences with some, so can people please post their experiences here to help me deciede...

cheers Aaron

They are not all the same.

Tomei is the best in the market for crank direct driven oil pumps for this engine.

The rest are on par with each other although some flow variations are present between models.

The N1 pump is a nice upgrade if you just want some cheap insurance, the other pumps are if you want to be making big hp reliably. EG. over 450hp at the wheels. Unless you are going for big numbers, stay with the N1, otherwise, JUN or Greddy, then if you want the Roles Royce go the Tomei for absolute insurance and peace of mind.

And then Dirt Garage just advertised an external pump system so take a look at that.

won't you need a crank collar too?

Not if you use the Tomei pump.

The other ones, yes it is advised to use a collar but if revs are kept under 7500rpm it takes years to do any significant damage in most cases.

not if he buys one of these

+1 for belt driven

He's only using 2530s and im assuming a reasonably sedate build...

So N1 pump.

vspec-gtr32 - next time please use the search button, most of you latest threads have been covered many times so have a read around before cracking out new threads as there is lots of prior info about for most questions

Tomei....I am no longer a fan of JUN pumps. But for not much more than a Tomei pump, you could get Dirt's group buy external.

Im getting a nitto oil pump installed right now. Suppose to be a great product at a descent price. So theres just another one to look at. Goodluck..

[vspec_gtr32]

cheers guys,

firstly, thanks for the info 3lit3 32, much appreciated, i defenitly want "absolute insurance and peace of mind", so tomei sounds like the way to go...

secondly, i have bought a r33 gtr crank so i don't need a clollar...

thirdly, sorry dirt but i want to keep my air-con atm and think it may be a bit of an overkill for a street car, but in sayig that pricing is very comparable

lastly sorry R31 Nismoid for the threads but there is so much B/S in a lot of them i don't have time to read them all so i thought it would be easier to ask again to get more of a direct answer..., in future i will try to read more..

thanks Aaron

Your not saying that cause of my slight little JUN oil pump failure are you mate...

I had a JUN pump and it cost me a very expensive engine when it broke into 5 bits on oran parks main straight.

The bearings are still stuck on the crank and the journals are bent to the point where you can see if with a naked eye

6 stage dry sump is now being used touches 9,800rpm plus frequently and never has an issue. Stupid crank driven oil pumps.

no he's saying it because his JUN pump just lunched itself.

why do you think im running a Group Buy on external pumps.

[Risking]

If you want absolute, its simply dry sump and big bucks.

Otherwise any oil pump can be killed with poor treatment, just like N1 pumps can go forever if treated right.

There isn't one brand of pump that hasn't been destroyed so depends on your definition of absolute

ive never heard of an external pump wet sump set-up failing either...lots less than dry sumping and less hassle. Why store your oil in your boot when it will live quite happily under your engine.

Interesting read. Definately wanting to go with the external pumps that Paul is teeing up... Otherwise i guess Tomei are the gucci pump on the market for crank driven at the moment.

[T04GTR]

tomie pumps break too. got a stock crank it will still break if pushed.

[T04GTR]

if i had to do it again id go external then i would be able to go 9k+ with the right head hardware. as it is now im stuck to 8.5k with my jun pump.
