Rb26/30 With Hks 2510

[Guilt-Toy]

I got a set of HKS 2510's for my RB30DETT, only thing is that with the stock turbo's its making 280+ rwkw, and from what i can see these turbo's wont make anymore power then this...

anyone used them before? is it worth installing them? I don't get why HKS would make a set of turbo's that are not any better then the stock r32 twins?

anyone have any ideas or suggestions?

how much power should these 2510's make ?

[R31Nismoid]

Given 2530s are bigger than -5s (400rwkw+)

And 2510s we the baby/response upgrade, probably similar to either -7 or -9 - so 300-330rwkw perhaps?

Perhaps look @ the Cartride tag, might tell you more of the story.

Or work it out from the comp wheel and compare to a -7/-9

I've got a pair of HKS 2530s here with stuff all kms on them, rear housings have been HPC'd

[Guilt-Toy]

seeing that it has the steel rear wheels, and a extra 50kw at the top end... should not be soo bad of an upgrade...

i really do enjoy the stock r32 turbo's to be honest but i do not know how long they will last on 14psi with a rb30 spinning them up

[R31Nismoid]

I'd probably guess not too long, and if they do let go - motor could go with it

If you've got em off - measure the wheels. Will give you the easiest way to work out where they "sit" in relation to other more well known offerings

2510's should flow similar/maybe slightly more than the 34 N1's.

I had a set on my old GTR and they were just as responsive(From my point of view) as the few stock turbo'd GTR's i had been in.

[Guilt-Toy]

what power did you make?

with the stock turbos on a rb30, if i don't want them to fall appart how much boost should i run??? not keen to rebuild this motor from a turbo letting go.

[Crans]

No Idea on power. I bought the turbos with the engine but did some research before handing the cash over. A few UK GTR owners were getting 400 - 420rwhp on them.

Not a very widely used turbo from what i can see

A close friend has a 2510 equipped GTR, I consider his car to be fairly well optimized in terms of supporting mods.

The 2510s feel to have an excellent top end and are fairly linear down low but have a fairly sharp shift onto power. Sort of like a big single.. they have the low end pull of a 300kw turbo, and they make just over 300kw.. but they have the lag of a 350-400kw turbo lol

This is just my feeling, and I flat out keep telling the guy to swap for a single but yeah... Hes spent enough money. If I was you I would sell them and buy a good quality singe manifold then bang on a 300kw capable single and reap.

[R31Nismoid]

Guilt & I were looking @ specs quickly earlier and they are sorta in the middle of a -7 and -9

Bigger comp, but a tighter trim so they *should* be somewhere between a -7 and -9 so 320-330rwkw and about as responsive as it gets. Shouldn't feel "laggy" like a -5 set would.

[Guilt-Toy]

looking in the engine bay today... looks like it will be quite a mission to put a big single in the Z engine bay, the twins are just about touching atm.

might have to stick with twins on this car... besides 330kw at the wheels is good for a daily streeter with a stock rb30e bottom end.

[GTScotT]

Check out the specs of the exhaust wheel and consider that too much flow from the front side for the rear more or less would stall them. I think thats their problem, they choke on spool and take a little longer than expected to wind up.

Probably worse on a 3L too

[Guilt-Toy]

turned the boost down for now on the stock turbos.
