do a search for PartsCo , new zealand mob i believe, they carry a good extractor option for N/A Skylines, You'll also need to purchase the Exaust Manifold gasket, (~$90 i believe).

1989-98 Nissan Skyline R32, R33 - RB20, RB25 DOHC. 1 1/2" Primary 1 3/4" Secondary 2" Outlet Part #D12

That should do the trick :) Im also doing the extractors at the moment, im pretty sure im gonna go with the Coby's, unless someone can advise me otherwise.

i can get some pics for ya tomorrow, ummm coby extractors with the rear collector modified to 2 1/2" then to a highflow (hollow) cat through a custom made 2 1/2" pipe through to a titanium tipped stailess body cannon, with the cool blue titanium burn on the end of the tip, whole exhaust is mild steel and built specifically for a 25de 33.

thanx heaps guys, I'll be lookin in to gettin the coby's as well.

yep i agree with you . i adapted a set of rb30 extractors by getting new flange plate made and welded it on and one of the pipes had to be lengthened . i got a workshop but if you havent , far better to go the coby route . they sound great with extractors and decent exhaust , sort of sound a turbo certainly cant make cos theyre muffled by the turbo (sorry turbo guys)

  • 3 years later...
any1 have a set of coby extractors lying around?, extremely keen on getting some ><

I have the extractors from dondesoto, the rb30e ones with an rb25 faceplace, though they are to suit an r31, so you would have to get an exhaust shop to cut and shut it. I replaced them with some fujitsumoto's that dump into 3" for my rb30de

    • thanks mate, one of the reasons I even bought it to be fair.
    • I found parts on EFI Solutions webshop that seemed to be the accurate ones. I haven't gotten around to fitting the turbos back on the car yet since I still have to deal with the shitty crack in the engine block. But I'm confident that the bolts I ordered will fit. According to EFI they are also 7-16/24. The reason M11x1 got involved here is because it is apparently very similar to 7-16/24.
    • Well, to be fair to the car I've driven it daily for almost a decade now, although in that time only put on 50k, as it just recently passed 100k miles early this year. For the most part its been fine because I've been able to source parts from AUS like jacks jdm and a few places in Japan, some things like pads have been easy since 300z pads swap right in... I realize its probably at that time in its life i should find a new DD (but I rent and only have so much space, no garage) so new cars just complicate things. As it is older though, I recognize its about that time as with my '67 GTO to maybe side step and find an alternative, but if i can keep driving it... I want to.   That said, I may just look into a local shop that might be able to, problem is the mechanic I work with has limited space as a mom and pop operation, and he's a busy busy man, so id need to find out if he can keep the car in the meantime, which may or may not be practical for him. Maybe I'll just buy one off jacks jdm and get that refurbed /shrug.. just looking at options and what others may have to offer for advice on the matter. Like I said, its hard finding people around here who actually have one, I've had mine 9 and a half years and I've met 3 others, and they are all military, one was oem from 95 with 30k miles (rip that car... guy got hit after someone crossed s double yellow, totaled it)
    • I've noticed my rear springs sag a bit compared to the fronts. I have stock springs and KYB struts. The front wheels are pretty consistent in their ride height, but compared to the front wheels, one of the rears sits 20mm lower, and the other 40mm lower. This negatively affects the ground clearance, and also angles the headlights up. What are some some economical options for new springs? Or information like good spring rates, lengths  in order to find a suitable replacement etc Far from lowering the car, I'd prefer to raise it a bit to keep it ground clearance friendly.
    • I searched for ages as well, I'm importing an engine to get the head off it.
