Ok, I feel my GTS-T is feeling a little neglected so I'm considering a 100 hp shot of NOS on demand on WOT.

RB25/30 - GT3076R - Haltech Platinum 2000. 337 rwkw.

Good move ?, or should I save the dollars and wait until my kids pillage it all.

I don't drag it.

I'm hoping for a setup which the Haltech can introduce Nos only in certain gears , revs and at WOT.

But right now my injectors are maxed , my intercooler has 2 1/2 in and out, and I'm running stock manifold.

Will I still get anything more with NOS ?

As long as your exhuast is up to the extra flow, yes you will see great gains. The stock intake manifold makes it easier to get a more even distrobution from single point of injection.

Your intake pipework etc wont affect the amount of extra power you can gain from nitrous.

The trick is to get the nitrous consistant. To do this you will need a bottle pressure gauge and heater on a pressure switch.

Is the engine still stock internally? If it is, I would suggest no more than 75ph fixed shot or 100hp progressive shot. If it's built, then think 100 fixed and 150 progressive, depending on boost pressure etc.

Cheers

Put a twin scroll 3788R on it instead!

I dont usually go for performance in limited quantities. Id prefer to know I can hoon interstate if I wanted to LOL

Le mans 24hr of Hoon

So get a G size bottle :woot:

Will lift the bonnet and intake manifold 10ft off the ground if it backfires though lol

Yeah... leanouts/nitrous backfires are pretty spectacular. Only ever seen them on carbied engines though... not saying it can't happen, but I've never heard of a backfire on a FI efi engine (engines that don't mix air and fuel inthe intake manifold 'plennum').

I think it's a great 'power adder'. There is no real trade off for the extra power when you'r not using it. For an extra 100hp of kick, you don't have to use a bigger turbo- more lag, you don't need bigger injectors- fuel economy/tune resolution, your not shifting the power curve up or down- if your using cams/cam gears, there's very minimal down time for install and it dosn't cost a bundle. Not to mention the dyno curve goes straight up at activation- ha ha ha!

Thanks for all that info.

Yep car is built forged bottom end, Poncams, and Plazaman plenum.

Exhaust is stock ex manifold to 3 inch.

Intercooler has 2.5 either side.

3076 is 0.82 Ar, should have gone 1.06.

Running 21 psi now, does have more in it.

it does feel like its choking at high rpm

      R33 GTS25 NA - Stalling when vehicle is at operating temp

      By TurboTapin · Posted

      Do the following first and get back to us. - Clean and verify your IACV - Verify for vacuum leaks/post MAF leaks. (Pressure test is the best and cheapest way) - Do you have a BOV with stock ecu/MAF? If so, remove it.

      R33 GTS25 NA - Stalling when vehicle is at operating temp

      By DRoc81 · Posted

      Hey all, The skyline I have is stalling when the engine is at normal operating temp.  When starting it while it is cold, it'll run just fine.  I have replaced the battery (bad cell), I have replaced the fuel pump, fuel filter and clean the MAF sensor.  Any other suggestions?

      Thanks for all the information on this.  I tried ordering the parts from Amayama website and all 3 Solenoids are discontinued and not available.  Does anyone have any other websites to suggest that I could find the parts?   Separate issue-- I will start a new thread, but basically the vehicle is stalling when warmed up.

      It's unfortunate what Tomei USA has done to Tomei's name in general. I'm very weary of ordering parts from them now. I only order direct from a Japanse source (e.g Nengun). At least their logos are different, so you end up knowing what you have.

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      Update Issues 5 (plus #4) - 10 After making a claim about issue #4's missing part, DeAgostini Japan sent a whole new issue #4 and it arrived about 2 weeks after that. That was back in early March. It took another 4 weeks to receive issues 5 - 13 though. This update is for issues 5 - 10. Ove the 5 issues the front left suspension and most of the engine have been completed. The quality of the castings and fit of the parts is quite good, it seems better than DeAgostini's BNR34 Skyline GT-R from the Fast & Furious 2 movie, which (to me anyway) doesn't seem to have as tight tolerances or quite as accurate castings.  Each issue has a lot of info about the 1989 - 1993 Skyline range and other Nissan models from that era, but the focus is on the BNR32 Skyline GT-R Nismo and the various racing it did in Japan, Europe (Spa 24hrs) and of course Australia. I've included some text translated with Google Lens in some photos and will add to them if there's anything worth including.
