I've done a lot of reading and searching, but i'm trying to find a good turbo upgrade that doesn't require any supporting mods that most of the turbos mentioned use to get the most out of them.

One of my stock turbos has given up. So i need to upgrade, but don't want excessive lag. Any ideas? GT2860R? I'm just not sure what version.

cheers,

andrew

Well what constitutes "worth the effort"?

Stock turbos will run into the low 300rwhp quite happily.

There is not a huge amount of room between that & the point where your AFM's & fuel system run out of puff.

As for cam gears. There is a thread somewhere where bear baron has posted a dyno sheet of the before/after results. Most useful. The cam gears that is.

I'm wondering the same thing.

What would you say the minimum supporting mods would be for say a GT2860R to make it worth the effort?

Do you need computers / cam gears etc etc.

yes.

Generally Fuel pump

ECU, Cam gear, full exhaust, decent clutch... they are all a must.

Injectors if you want a little bit more out of it as your likley to max out the stockers before you max the turbos.

Cheers

I went the 2860R-5s, Great mod. As above really... ECU, Low restriction exhaust-inc, dumps and front pipe, free flowing cat and cam gears. Then the next spend would be turbos, fuel pump and the injectors ...unless you want to plonk down the coin all in one go. Then 32R suspension GB then some reliable gauges then wheels then ...... :ermm:

If you don't want/have any support mods then the smallest of the three version is the one for you.

:laugh:

But mis_quoted I believe.

GT2850R turbo's come in 4 Versions.

N1,SS,-5(2530),-10(GT-RS).

Buy either the N1, or SS.....same size housing as the stock unit no EPA probs.

Cheers

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
