Best Extractors For Rb20de?

[Murry33]

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?

Im in adelaide by the way,

have you tryed a seach? there is a thread about extractors for a rb25de on the 1st page of the na forums. have a look on there to find a little more info

i paid 275nz dollas i think from memory for some COBY extractors

yes they are well worth the money and you will feel the difference

[Murry33]

i found threads on rb25 but not really on rb20, i'v heard the coby ones are good.....where are they usually sold?

Cheers!

[BADR33]

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?

[Murry33]

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...

haha yeah i wish i had too... live and learn i guess. the sunburn on my lower back made driving painfull for the next week or 2 haha.

hopfully when i get my custom rb30 extractors ill heat wrap them before fitting too.

[Murry33]

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!!

[BADR33]

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.

[Murry33]

custom heyy sounds good!!, how much power they add roughly to an NA rb20DE??

I just want it to sound nice and a little more power, without the turbo of course

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

I just bought a set of RB25DE extractors from Coby through partsco.com. Really good bunch to deal with, both Coby and PartsCo, and great price delivered to local post office.

PS: Coby will customise anything to your needs too...

[Murry33]

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
