hey every non turbo owner, im in the process off thinking about getting custom made extractors made up to suit right hand drive zeds. i will need to talk to the shop more but im pretty sure if i get enough people they will consider making them. this is just a *** for now so nothing definite yet. im not too sure on cost either i will need to talk to the shop. ill let you all know if anyones interested just post on here thanks
I've looked into this before. Guy who pieced my exhaust together does hot rods / V8s and I've seen his custom long tube headers. He told me if I wanted a serious piece of gear over the off the shelf bits I provided him, he'd be willing to make a V6 set for me. Let's say the price wasn't justifiable, I could buy a couple of TT motors for the price. Custom stuff is expensive. Most good exhaust shops can make a set for you but I dare say the price is just way out of most people's budgets.
cheers dave, ill talk to them on monday so hopefully i can convince them to make a few sets depending on price
The astute performance tuner would understand that its not as easy as putting pipes together in a way that gets the exhaust out the tailpipe. Its a bit of a 'black art' that many people in the local exhaust shop claim to know, but few actually understand. There is a LOT of thought that goes into runner length, flow characteristics, the merge collector, even down to the firing order of the cylinders. 'Tuned length' runners fatten out the torque curve at a point, but can sacrifice power elsewhere- good for a race engine that lives at 5K RPM all day, but not practical on the road. Some of theses even use the pressure waves generated by the movement of gas out of the cylinder head to help 'suck' gas out of the next, it gets pretty complicated. Nissan headers (while with some degree of cost constraints in their manufacture) work well, their design aims to improve power delivery throughout the rev range. No doubt a team of highly trained professionals had a reem of calculations to back up their design decisions. Designing your own would ne be feasable for a small run. The astute business person would approach the missing-in-action TTZ performance proprieter, and offer to purchases the Jig for RHD 'stillen copy' headers. These were backed up with dyno results, and have had a fair bit of R&D over the years. Im not sure what arrangement was made between the designer, the manufacturer and the owner of the rights to sell them (TTZ), but for the love of god... someone please fill this space in the market. Hell... if any business angels out there want to spot me a few grand I'll manage the whole damn thing, and profit-share the shit out of it :zlove:.
I went down the road of NA extractors, while they are a decent upgrade to an NA they'll often cost upward $800 (parts plus install, cheaper obviously if you install yourself). ie I paid $600+ for TTZ headers with gaskets and postage. Then a further $300 to install. IMO with the benefit of hindsight - keep the money and spend it on a TT (or alternative) when you're off your P's/get an ACT/WA/NT license
keep me posted please Ive been hunting for RHD extractors for ages-you've obviously been having the same problem I guess-TTZ used to make them-it's such a shame the yank sets dont fit because they are beautifully made and so cheap!
thank you for your insightful message- I have been scouring every country in the world looking for a RHD set and am as frustrated as a bloke can be on the subject. Sad loss to us all was the TTZ resource for headers-if there's any way to be helpful in this process please let me know-regards Paul in darwin
Look, I get this. BUT the big turbo swap is certainly for some but DEF NOT all. There are enough NA officinados around here who are not the slightest bit interested in the big power. They prefer the whole driving experience as opposed to the big rush when the hairdryers do their thing. Not everybody want to blast down the road, sideways in 3rd, turbos squealing, smoke, flames and sparks from the exhaust with their hair on fire and laughing hysterically!! Some of just enjoy the more leisurely and linear power result (not to mention a much sweeter exhaust note) an NA delivers without the added complexity and hedfark of converting to a full TT setup. I dont care what you TT guys say about your exhaust notes and ill have the firesuit at the ready here BUT, there is not a turbo car made in the world that sounds much better than shite-house compared to the glorious growl/wail of even a partly well designed NA exhaust, REGARDLESS of the engine config. Sorry, WAY IT IS! However, I do agree tho that costs approaching 1 large is a bit ask for a few extra killerwasps from a new set of headers unless your totally hellbent on having them. Thats the thing with all relatively modern multivalve NA's. HP increases due to the usual modifications are just incremental at best and are nowhere near proportional to the dollars put in. Engines are often pretty well optimised to begin with apart from inlet and exhaust systems which are usually restrictive due to rules and regs rather than poor design. Given how well they actually DO perform at zero noise factor is pretty impressive when you think about it really....... Its relatively easy to squeeze out more power from the blown engines (to a point....but its a pretty big point tho!) HOWEVER, in the NA V's NA scheme of things, a comparison between a bog stock and a much modified NA will show quite clear results. Comparing NA performance to TT performance is really a woftam. Its just apples to oranges. All my NA requires is some old fashioned 30/70-70/30 and 285 thou lift cams to give it the same raspy roll as an old XU-1 at idle!!!!!!!! Long live the NA I say!!!!!!!

I agree. I drive my NA every day. The TT sits in the carport most of the time gathering dust. I drove it today for the first time since the pink slip check early april Now I'm not hating on the TT, but my NA is so much more driver-freindly, despite having no clutch vac assist, and mostly stock gear (except extractors and a dusty yet polished plenum lol). My TT is a pretty good example too; it's rebuilt, mechanically and aesthetically good. I still think that if it came down to it, the NA is a driver's car while the TT is just a pure power machine, ready to kill you at a moments notice. :br:
