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.

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!

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.

INASNT,

check this baby out, it might be just what you need.

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

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.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
