Hey

Just looking into camshafts for a motor I am looking at building...

Does anyone have some info about these cams?

Specifically for a decent sized twin turbo setup (GT3540) with other head mods to suit (Valve springs, retainers and lifters)

Which lift and opening would 'ideally' suit this setup?

They are available in the following;

Inlet

280 / 10.7

288 / 11

296 / 11.3

304 / 11.6

312 / 11.6

Exhaust

280 / 10.3

288 / 10.7

296 / 11.1

304 / 11.4

312 / 11.6

THanks

in my opinion.. your looking WAY to bigger cams for that turbo.. go for something more along the lines or either basic pon cams.. 260 9.15's or 272's.. cant remember who it was.. but there's someone out there that does 260's with bigger lift than 9.15mm just.. cant remember who makes them

it says twins not a single rb26s13 so they are perfect sizes, poncams are tooo small :banana:

i got 272/11.35mm lift and im running a single t04z so it just depends on what u want to do with the car.

bigger means more lag and higher efficiency in the higher rev ranges. but smaller will kill the max power and top end pulling.

thats my 2c worth

With those turbo's your going to need to spin it to like 11k before anyhting is going to happen. So I would go the biggest cams you can find. Hope you have good valve springs. And bigger doesn't mean that there will be more lag esspecially if you dial them in appropriately.

    • The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow

    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
