Will HKS 2530 give me 250rwkw

[RS500]

INASNT,

P.E.T Mods are located in thomastown (as per below)

P.E.T Modifications

7 Hanrahan St

Thomastown 3074

(03) 9464 4225

the last R33 they worked on was pushing over 400hp at the wheels on their dyno.

they built the EL Falcon that runs 10.25, although most of their work is around RB's (VL's, GTS-Ts and GTRs), etc.

Dennis is very cluey when it comes to turbo combinations and the like.

give him a call, he'll be glad to speak to you.

[Guest INASNT]

thanks RS500

i will give him a call next week once i get all my finances sorted out.

[RS500]

no probs. let me know how you go ([email protected])

Inasnt, have you had a look in the for sale section? Munro is selling his HKS 2835Rs pretty cheap, esp considering that they are nearly new. I have seen a review of them in Zoom or HPI and they seem like a pretty good turbo, and will definately get you to 250rwkw.

yes but they r high mount and i will need to get a custom manifold made for em!

Taked to gerald from ice and he said he has worked on a r33 like mine with 2530 and at 1.4 bar it did produce 250rwkw!

[ice180]

slight porky it got 240rwkw that would be mona's.... at 1.3 bar I thought. did need some serious tunign though only had some kind of jap chipped ecu to run the Z32 AFM..

[Guest INASNT]

was it the 1 from sydney? thats the one gerald was talking about

[ice180]

yes it was dens think it may have got to 250rwkw but they wound it back as it was starting to ping slightly. go the 2530 you won't regret it.. give some stock gtr's some curry.

[Guest INASNT]

240-250 its all good!

got whole of this week off to work out what i am gonna buy

[ice180]

how come you are not cruising.

budget for

power fc with h/c

injectors 550cc min

turbo

dump and front pipe if not already

z32 afm

fuel pump

decent front mount cooler u already have right??

and also ya stocky or even peformance clutch won't last long I'd say twin plate.

also good elec boost controller if not already

5 - 6 g should do it maybe cheaper 2nd hand parts.

fark now I can see why mona's car was such a bargain plus she had the teins, front and rear strut braces, active diff, anti slip and all those gauges heheheheh... Nismo speedo also.

[Guest INASNT]

i aint crusing coz my car is back to stock form for the epa test tomorrow!!

dump and front and hks fmic already done, will hold off on injectors and fuel pump till a bit laster, will try pam them all out at about 220rwkw till i get the new stuff

from all accounts i have heard about the 2540 its a big mismatch with exhaust and comp wheels!

rev

i have heard a 2530 pull 230rwkw at about 1.3 bar.

havent made up my mind as yet, i have the $$ to buy 1 but can coz i have had delays starting my new job

[West]

I got 191@wheel with stock turbo and 12psi as well, what i think is if we Hi-Flow our own turbo, cams, fuel system we should be able to get that far without spending too much dosh here. By the way anyone knows if GTR cams goes straight on Gtst? Any mods require? what's improvement?

INASNT,

this is HKS website info on their turbos:

http://www.hksusa.com/categories/more.asp?id=1092

They rate their 2530 at 320ps, with allowing about 10% for their known underating, makes 352ps - that is flywheel. Assuming standard driveline loss for GTS-t, 80ps (or it might be 70 but close enough for demonstration), leaves you with 272ps at the treads. Pretty close to 200rwkw! The 2530 is pretty popular on GTRs, but they use 2 not 1.

These are HKS's own figures. You probably could get more, but how efficient would the turbo be operating. If you are after that sort of power (200rwkw), the stock turbo will do fine.

If you upgrade, and want 250rwkw you will have to look at something like the GT2835. Two on Munros car was making 900hp- 450 a piece. Subtract 80 for driveline loss and you have370rwhp - about 270kw. This will allow you to run lower boost to achieve your 250rwkw, and still have a bit of head room. I realise you dont want to go external wastegate, but consider the advantages of going down that path. Your car will make boost quicker and will have very good boost control. You can pick up a external wastegate for under $300, and either a second hand manifold for up to $800 or you could get a mount made up to adapt a wastegate to the stock manifold - might be an added $300 but i doubt it would cost that much. Then another $300 for a dump pipe.

Not the best setup, but you will get the power you are after easily. I really do think you are barking up the wrong tree with the 2530, and in the end it will just end up costing more to get it replaced when you dont get what you want.

Your cheapest option would be get a good highflow, somewhere like GCG that has proven results at a reasonable price.

If your workshop tells you that you can get the results you want with a 2530 - get it in writing before commencing work and find out what sort of other considerations need be made - I would especially be interested in how much boost they would be needing - too much and you will have to decompress the engine which will kill off boost driveability. Also once you have got the head decompressed, you may find it would have been cheaper to get the right turbo in the first instance.

Its always nice to find the best most economical way to get performance from your car, sure you can pick up some bargains, but make sure you get the right piece of kit at the right price, not the wrong bit at a great price. It will only cost you more down the track - do it right the first time.

Please dont think I am having a go, just hate to see someone make an expensive mistake. Just trying to add something worthwhile - if you want good performance it does cost dollars.

Steve:)

[rev210]

steve, you'll be interested to know thats flywheel PS NOT rearwheel power a common mistake people make.

[Steve]

Rev, a very valid point, in my last post I mentioned that you need to allow for driveline loss - but that is definatley worth mentioning seperately as I think alot of people overlook that one.

Cheers

Steve
