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 !

      My plan is to go the pink option. But still add the 4th fitting near the oil cap and just cap it off for now.  That way I can add 2 extra to the sump and have 4 dedicated breathers/drains if I ever remove the sump for any reason.

      By GTSBoy · Posted

      Oh, yeah, look - here's the thing. You always replace the tensioner when you're going in there to replace a belt....under normal circumstances. You want to make sure it is good and safe, and that you don't create a reason to take the front of the bloody motor apart again. But in this case, OP is replacing a belt that has aged out on time, not usage. The belt is a million miles away from aging out on usage. The belt gets a time "limit" merely because it is made of rubber and can degrade naturally. The tensioner? Not so much. I reckon it could last forever on the current usage pattern. So I reckon if the thing is going to continue to get used at the same rate, replacing the tensioner is somewhat gratuitous. Would I replace it if I was doing it on my car right now? Hell yes. Because my car does 10-20 thousand kays a year. So it's all going to be the same thrashedness. Would I YOLO it on OP's car. More than likely.

      I dunno. I think any one of those from each side to sump is probably enough. Remember - this is about creating a path for gas flow up from the sump to the cam covers. That gas flow then has to leave via the lines to the catch can. There's probably little point in providing 100% more capacity from sump up to covers cf. what you have from there to the catch can. Put in the 3 convenient ones? Any which way that you see fit. That'd be my thoughts.
