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.

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!

Cheers

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

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.
