"...telling the ECU that the incoming air in the intake system is cold and so advances the ignition to compensate producing more power"

What the hell? That first bit about temperature aside (which has been discussed), couldn't you do the same dangerous thing just by rotating your crank angle sensor a few degrees? That would cost all of $0! I wonder what the hell it actually is that is costing you the $35.

The only legitimate cheap/free performance enhancing mod I know about is with late model Suzuki sports bikes (mine included), and it's nothing to do with the inlet temperature. All it does is trick the bike into thinking it's always in 5th gear, to give it an extra 2 degrees timing. Suzuki decided to de-tune the lower 4 gears to make it a bit safer to ride (less wheely-ing tendencies) and a simple resistor in the right place can change it and turn the bike back into a tank-slapping bitch. Of course, you could just advance the ignition 2 degrees manually with the CAS, but then 5th and 6th would be 2 degrees too advanced and it'd probably ping.

Edit: I'm not suggesting anyone advance their timing without a proper tune! Just saying this in case you didn't notice I said "dangerous" up there.

      Compatible rear drive shafts R34 N/A?

      By GTSBoy · Posted

      They should do. I have S14 (or something S chassis, anyway) driveshafts in my R32 (because my diff flanges have 3x2). They're the right length. When you go looking for R32/3/4 driveshafts (for turbos), they're all the same thing, so are the same length. So there really shouldn't be any reason why those cheapies from JJ won't also fit an R34. R32/3 NA should also be the same thing. The (3x the price) D-Max ones are uni-fit. They have 5x1 and 3x2 bolt holes and say they cover all the cars. So that would also suggest that they are all the same except for the flanges. And in that case, the flange goes both ways. I'd be buying the D-Max ones if I ever have to replace a shaft. Because that will open up diff options without needing to juggle shafts also. Juggling shafts is gay.

      GReddy Injector Help!

      Yeah with the adaptors they do look like the photo above - just the fitment within the plenum itself and then further with the rail to the intake is questionable - we shall see tomorrow hopefully once I get some replies from Aeroflow, maybe those bosses are the missing piece....

      Should be fine, if you have it sitting too far in, you end up just spraying the walls and have shit idle. You "can" run them like that, however I don't think it's a great idea (also depends on your plenum, might be good to just get the injector bosses first, mock it up and see if you need to get the bottom extension) Ideally your injectors, with the extension should look like this  (Not my photos, just Google)

      Thanks for the replies guys, it's really appreciated.  It seems the kit was supposed to come with those injector bosses but hasn't. Unsure if they'll help as even with the adaptors to make them a 3/4 height injector they still sit too far out so mount the fuel rail?

Do S13/S14/S15 or R32 NA/ R33 NA fit? https://justjap.com/products/gsp-premium-rear-drive-shaft-l-h-nissan-silvia-s13-s14-s15-3x2-type?currency=AUD&srsltid=AfmBOoqY7EwDaYCUoUU3mxxZ_qrUXkVVHiV4MIN7ozoar6scjnEiekv- would this fit?
