Damn, that is a huge increase, NismoGTSX. I might have to reconsider it. I'd talked myself out of it, but this is good to hear. Have you got any more details of your mods?

dAVE:

I didn't notice your comment to me about Merli. Thanks for the tip. I've just spoken to him about it actually.

Nahh - its got a fair bit more than 300... Probably more like 330... It makes 300 by 5000rpm, and then broke traction past 5500rpm, so I'm not sure of it's exact figures yet. It revs to 7500....

As for how quick down the track... Not sure if I'm in a hurry to run it... I've spent god knows how much money on it to get it to this stage, and it's suspension setup is for track work...

To run a decent time, I'd have to fit an auto box, and some sicks, plus some front runners, and that's money I'd rather not have to spend...

When I end up selling it, I might spend the $$$ just so I have the slips for 10 seconds when I sell it.

BTW - MIC33R - I'm not saying that the plenum's a complete waste of money... I'm saying that for that sort of $$$ outlay, you could spend it better :)

I have a custom plenum on my car, but i cannot really quantify the results of just the plenum, as I did alot of mods all at the same time. It definitly helps reducing the length of pipework but at my level (205rwkw) I don't think it makes a noticable difference. Another thing you have to factor in is alot of custom plenums remove the factory idle sensors, etc from the plenum which then requires a full computer.

Pics of my plenum are here www.mfx.com.au/team/prgen.jpg

Details on moy mods are here http://www.mfx.com.au/team/pages/prg.htm

Darren at Mood Motorsports made my plenum, which I believe is a much better design than the Sub-Zero item due to the tapered design. The Sub Zero one to me looks as if it favours the first few cylinders, and would starve the last few.

If you give Mood Motorsports your manifold, they will make the polished aluminium plenum for $850. He also did my pipework and I/C for $2000. I can't speak highly enough of his work, it is excellent.

Just tell him that Jeff from MFX recommended him.

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
