Hello im after getting some extractors for my r32 skyline na, i want to increase performance slightly without going the whole turbo conversion.

How much power gain do extractors give roughly? which are good value for money? What kind of prices?

I have an apexi n1 exhaust system on the car already, just want to add to that.

Anymore ideas? :starwars:

Im in adelaide by the way, :)

rb20 is pretty much the same as a rb25 for the extractor threads.

you can buy them in NZ easy as. there is a parts site that is listed in the other thread that exports extractors.

prehaps you aussies need to organise some group buy on them?

really so rb25 extractors would probably fit straight on to an rb20de? :)

if anyone has some websites or prices could they let me know? Cheers!

www.partsco.com have them for the 2 litre. Around $240 plus $100 for freight to oz. Just wish I'd heat wrapped mine b4 fitting...

hello again, i'm after getting these in adelaide can anyone recommend a good place to get them? also ...

How come some people say you should really heat wrap them?

How much/how hard is it to heatwrap them, is there really a benefit in doing this?

Thanks!! :P

heat wraping helps keep some more heat outa your engine bay. um you heat wrap them yourself. i paid $50 for like 50'x1" of it.

i have heard people say do and some people dont. my new extractors arnt heatwrapped as the exhuast guy who i know well said dont do it as the heat gets held in the metal longer and they become brittle or somthing.

you can always get them heat coated.

you could get some custom extractors made up? mine cost me $650 all up as i got them to do some other work on the car as well.

hey mate - seriously no one can answer all your questions exactly, best way is to do some homework and make some phone calls.

rb25de extractors should fit an rb20de

as some people above have stated, there are possible pros and cons in heatwrapping extractors - that is entirely up to you.

partsco sell extractors - but if you want a price you are better off calling them or emailing and asking for a quote. (coby, hurricane, fujitsibo, there's quite a few brands out there)

you can also make custom extractors (muffler shop should be able to do it) - probably using your original flanges, and again the amount of power it adds can be anything, because they are custom.

i think you're looking at this whole "extractors how much power do they give?" a little one dimensionally. from what i have read and what other people have told me, extractors give allow better breathing and flow of exhaust gases.

you may/may not see much change in any max power (or dyno power read out). instead you might find a more drivable and chunkier/fatter mid range. there is no rule of thumb as to how much more max power you will get, but i would hazard a guess at ~5-10kw

Cool thanks that's answered all of my questions actually, and yeah im going to make a few phone calls but i'm just wondering if ordering interstate will be a good idea rather than local. Most people say coby are the best, so perhaps i might go for them unless anyone has another brand they know are great as well?

cheers

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      RB20DE NEO smallbox clutch.

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      Lock up the old for sale / wtb threads.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
