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 ?

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

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

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

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.

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.

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.

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

      R33 GTR running -9 with no tune

      By Murray_Calavera · Posted

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      By GTSBoy · Posted

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
