Hey all. Have a NEO 25DE head going on a 30 block. Looking at buying a Plazaman intake. The plenum i'm looking at is the "top half" that bolts onto the factory runners.

Is there a difference in the design of the manifold/runners? I am guessing that this plenum would bolt onto both. Can anyone confirm please?

Thanks Chris

i have not got one here to compare though.

Ps the KU plenums from ebay are quite good too (used a few now with excellent results), might save you some coin. :)

Interesting. Guess i might shoot over to the rb30 forum and see what others have done before.

Talking to the bloke from plazmaman, and he says that most people buy a set of turbo runners and bolt them on.

I just had to buy a whole turbo Neo motor to get this guy the proper head. The original head I sent him came out of a non-turbo R34 4 door. I thought it would be the same from information I read on this website. That information was wrong.

I notice that in that thread there was a reference to casting numbers on the heads themselves. Dont suppose you ever worked out which casting fitted which manifold at all?

Got a feeling i am up for an expensive and rather shithouse custom job now...

We are still working that out right now. I've got a head packed up and ready to ship as soon as we find out. I think I might wind up sending him the intake gasket to see if it fits.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      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...
