i got a hks to4z on a 26 making 360kw on only 15psi and revving to 6000rpm (fuel issues above that), booked in for new tune now as i found the fuel problem. 10 000rpm limit should see around 380-390kw on same boost :laugh: then ill wind it up to 22psi or so and it should be interesting. thats only the 0.81 housing too

If you want the 400rwkw.

T04Z, it'll get upto around 440rwkw from what information has come around thus far

The GT35 will do it, but its going to be asking a lot of boost from it where the t04z is a lot less

You'll need a flag load more than 24psi to get 400rwkw from the GT35 mate.

Have a look at what people have posted, and also in the RB26 dyno results thread.

Most t04z equipped cars are making the 400rwkw on around 24-26psi with the other associated gear.

yerp mite have to go the 1.06 exhaust, i think sydneykid had one making :

Calcs..........

632 bhp = 472 kw less ~60 kw (2wd) = 412 rwkw

The average power from 4,000 rpm to 7,000 rpm is massive and it's not straining at all. A/F ratios are not over 12 to 1 anywhere and the knock is less than 20. Cams and a bit more airflow (no more boost required) it would make 500 rwkw easily]

Ah the old RB30, used it in the car once and then someone paid me enough for it so I could build a bigger and better RB31DET. The GT35R had a 1.06 A/R turbine, with the T4 flange. The compressor A/R was 0.70. Boost was ~1.7 bar (25 psi), the dyno graphs went with the engine as part of the sale

see what r33_racer comes up with...bugga hey

so my next question is where do i buy exhaust wheels from?

Edited by kastin

that dyno is known to read maybe a few kws more than others here but definitley not in the vicinity of 80 which i would have thought the limit would have been.

i still didnt believe it however a mate of mine went for a ride in the thing and said it was scary (hes been in lots of 400kw cars before). it did run a 10.8 (maybe 10.6) so that confirmed it for me.

it has stock internals with a headgasket, greddy intake and cams 260's (no porting)

The dyno sheet has no reference to boost... how do you know this then?

Its 20psi its not 450rwkw on PULP.

I wont believe that until i have a boost gauge in my own hand as it runs the numbers, just going by the compressor map will tell you its a tall story.

The MPH would be HUGE if it is indeed 450rwkw.

To many unknowns about that setup to pass it as valid

ok then, ill just post up bullshit for the hell of it.

the same guy (Lithium) on here went for a ride in it and i know the owner of the car. its on pump gas at 20psi running a power fc with map sensor (rb26 one). i didnt believe it but there is the dyno sheet, someone has seen the car run on the dyno and at the drags and its going to be featured in nz performance car magazine sometime soon. proof?

read your compressor maps all you want but at the end of the day all your going to be is an internet mechanic who can argue all day long about something you know little about. ill find out the mph so you can do some calculations or something :laugh:

Good you do that

Cause telling people they can make 450rwkw off a GT35/20psi on PULP with just 260 cams/no porting is a joke and would grossly mid-lead people

We'd better see a MPH well into the 135 range (140 possibly i think).

You'd also better send a letter to Garrett, they'd be interested to know about it aswell im sure.

well on 1.7 bar with our gt3040 .82 we made 375rwkws and 365rwkws on 1.5. After 1.5 it was starting to blow hot air and power wasnt increasing much as you can see.

So i figured with this new motor, with the only differences to the old one is that its now got a dry sump system, gt3540 .82, and 4" exhaust. We should be able to crack if not get extremely close to 400rwkws.

Am i being a little too optimistic?

Heres a link to the site showing the Japanese Performance r33 SirRacer is talking about, it has the list of mods and times ,it states it runs a gt3540 and makes 450rwkw on 19psi but it dosent say what a/r, all it says is (secret a/r), it ran a 10.65 @ 128mph,(mph seems a bit low for the rwkw) when i saw it the day it ran that time it didnt look to even to be stripped, it was just a boring plan looking r33 with slicks.

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
