This question may seem a little jewish, but here goes...

Are there any injectors that are standard equipment on another car that would work well as an upgrade for a mildly modded 33 GTS-T?

Further more, any truth to the rumour that XR6T injectors will work? I understand that the 33 has 'side-feed' units, am not sure what the XR has, but any input would be great. I am aiming loosly at around 250rwkW, not fussed, but dont want to starve things.

xr6T injectors are top feed, you can buy adaptor rails to run topfeed on rb25 but then you needa change injector plugs etc, or you could try source 6 jdm s15 injectors which are around 480cc? correct me if im wroung that should supply that power level?

Thanks guys, :( I would never believed that the squirters on a 2ltr 4-pot are that big! What would you expect to pay for these?

And do you know of anyone who has run them before? I'd be keen to know their limits, naturally, without finding out the hard way!

Yeah ask me !

Haha.

I would rate them at 450cc.

Getting tuned tomorrow hopefully (take 2 with a REAL AFM) with a HKS2535 and all supporting mods.

Supprised by the size of the injectors hey?

Wellllll.....

2.5 / 6 (cylinders) = 416cc per cylinder

2.0 / 4 (cylinders) = 500cc per cylinder

Not so confusing now is it ? :w00t:

Yeah, so easy swap out .....(DIY available in the appropriate sub-section)

And heaps of info .... http://www.skylinesaustralia.com/forums/in...146846&st=0

And 2 injectors for sale right here matey $125 delivered

Cheers mate...still thinking i might go the top feed 660cc siemens that ive been looking at as im probly gonna be chasing around 300rwkw eventually.

problem is my stock injectors are nearly maxing out at .8bar on the stock turbo.

hopefully an 040 pump will fix that.

hey mate, why dont you just go for drop in side feed injectors instead of top feed, such as tomei or nismo 740 cc injectors. Slide has them for $895 delivered. do you know what duty cycle your injectors are running. id say get a fuel reg as well if you want a quick fix solution to your injectors maxing out

I got one set from Slide Imports, brand new with a GTR R33 fuel pump for about $300

But thats for brand newies with all the rubber thingos to go with, see pics in the s15 thread i posted earlier.

2nd set from a written off S15 in Aus.

$250 delivered for 4 out of a 2002 model.

You should be able to pick up 2 sets for about $400-$450 and then try selling 2 like me and come out about $300 out of pocket which aint too bad

forget any other model eg. s12/13/14, no good to you if they are standard injectors,

s15 manual ones are the only 450-480cc injectors.

      It's not a dumb question. I was circling this idea myself. User error is always possible!

      R32 gtst speedo out by 10kph

      By GTSBoy · Posted

      Nope. The seal is in the drive. A new cable would just fill up and continue to convey oil to the speedo head. To check if this is what is happening, take the cluster out, dismantle the speedo and have a look. You probably don't even have to dismantle it. If there is oil coming up the cable, the drive into the speedo will be grossly greasy. I had to manually (and delicately) clean the gunk out of my speedo.

      Thanks for the quick response mate, and I agree Nismo 555s, Z32 and high flow 2871 in OP6 housing (run by PowerFC) would all be "period correct" and should be a simple, reliable and reasonably quick track car.

      It is normal for a speedo to read 0-10% high (unfortunately), intended by manufacturers and ADRs (although not in this case) to ensure your speedo does not read low if your tyres are worn. Speaking of which, what size tyres do you have on the rear, and what does they tyre placard say you should have? you can use this https://tiresize.com/calculator/ to determine what % difference that is causing Personally, when I buy tyres for a car I buy a size that will bring the speedo back to being more accurate; it if it reads 5% high I buy tyres that are 5% larger diameter. If you had an electronic speed sender like R33 onwards, the other option is to add a speedo adjuster but that won't work in R32. Finally, you  might be able to find a different sized gear for the speedo sender but that will be limited to what already exists (and I don't know what sizes do)
