Hey all, with the extractors that you place on your car what do they actually do like in performance wise because i have been told many stories about that they dont do much or they dont do anything and like they give you heaps of power and stuff like that but i am unsure of what it actually does.? thanx

I have yet to fit mine as im still saving up a bit of $$ to get them ceramic coated (not to mention find someone who does ceramic coating) But once fitting extractors, your power figure may not jump up, but a lot meatier, more useable band of torque through the lower-midrange of the power delivery should be expected.

i didnt find a huge increase in power uptop when i got my extractors fitted, but the power in mid range was increased 10 fold. It makes the car so much more fun to drive and gives it alot nicer crispier exhaust not, u wont be dissapointed. If i was ever to buy another NA car extractors would be the first mod i did to it.

i find my mandrel bent fujitsubo's to be a godsend...

a) the car revs a lot better, not as restricted as a standard manifold

B) makes the exhaust note really good (not so good when you don't have a resonator)

c) looks really nice under the bonnet when they're stainless steel :)

A guy I know got a 13 rwkw gain when he got extractors and a 2 1/2" exhaust system on his R34 .

I have extracors and 2 1/2" exhaust system, on my R33 GTS25. I would totally recommend them, the car pulls very well through mid range and keeps pulling till red line.

Hey guys looking at getting a set of hurricane extractors, just wondering if anyone on here has them? And if so what are they like?

RB25DE EXTRACTORS NEEDED .

Hurricane extractors , hmm , haven,t heard of them . do you have pics or where you can get them .

Also the fujitsubo extractors anybody know where you can get them or at least a pic of them

I modified a set of rb30e extractors to fit , but would prefer bigger primaries .

Yeah when i was fixing my exhaust i got them to check one last time for any extractors other than Coby and they found a place in Sydney that does RB25DE extractors by Hurricane. I've heard of the brand just havn't seen a pic and don't knwo anythign about them. I wasn't expecting anyone else to do extractors for non-turbo's. Obvioulsy they're mild steel but i'll find out a little more about them.

i ddint realise the rb30 extractors could be modified to fit the rb25de. Any pics? How easy was it to do dondesoto??

Cheers

Paul

not a real simple fix

went to an exhaust shop and they profile cut some new flanges useing the cast iron rb25de manifold as a template

then i fitted the flanges to the head to align to ports

put flat washers on the manifold studs then tack welded the flat washers to the flanges . that way your flanges are aligned as best as possible . at this stage i ported the flanges to match perfectly to the heads ports .

i then cut the flanges off the rb30e extractors .

to get the pipes to line up with the flanges , i had to cut the secondary pipe that is fed by the 3 front cyls then rejoin .

tack welded the pipes to the flanges

removed extractors from engine and welded it all back together .

now if i had my camera i would do some pics , but its not here so if you are still interested i,ll post some later ( there are 2 pics of my engines in my profile but dont show exhaust very clearly )

much easier to buy a manufactured set , but i allready had the rb30e extractors from the previous engine

the local exhaust shop was willing to make me a set for $650 , another place called Gonzo pipes said $ 900 but people tell me he is the best

the snakes help heaps ! trust me ! my old rb25de had a set of killer genie snakes on her, a quality simota air filter on it & a turbo muffler and the turbo boys used to have no chance !

my mates dad had a r33gtst that was boosted to 2 bar and over the first like 300 metres i had him cold !

for the measy outlay of $739 fitted, it really gives you a kick in the pants as opposed to one with standard exhaust.

Gotta fly guys, got turbo butts to kick !

    • I'd be very surprised if you can buy new OEM mats. But if you can, I want some too!  Do you have links to the variations you found? Also, where are you located? I found that Nengun is happy to list items to purchase but when you do buy them you'll get an email that it's actually discontinued. As far as I know the variations in floor mats are different colour schemes as well as automatic and manual having a slightly different shape. The automatic ones fit into a manual car without issues, but I think you'd have trouble fitting the other way around. I have photos that show the shape difference if you care. FWIW I bought sets of used floor mats in decent condition at yahoo auctions.
    • Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏
    • Hi, Marek here 🙋‍♂️. I finally fulfilled my longtime dream - recently bought Stagea and now waiting for it to arrive in Poland. There's only few of these in my country, and one of the owners  recommended mi this forum as a source of all the info i'd need since now i own one  so here i am.  
    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
    • and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.
