ok, my extractors are getting fitted tomorrow, they are cutting off the original final 2 into 1 cone that has a 2inch diameter and replacing it with a 2 1/2 inch one to suite the rest of my system. Ill let u all know how it goes.

Hey pipols, i got my extractors fitted last Friday, and i can only describe them as excellent, definetly more tork in the low to mid rev range, and it 'seems' to go harder in the higher end of the rev range as well, they allso enlarged the final few inches of the extractors to 2.5 inches.

cool greg, my exhaust is a little louder at idle, and a bit more throatier on acceleration, but i only have the standard exhaust with standard cat, with a lukey sports muffler, it seems that my standard exhaust is 214 inch in diamater, is that the standard factory size? im planning oh a high flow cat, and a 212 inch system soon, or maybe even a 3 inch, but dont know if the noise will be to much if i went the 3.

dont go 3 inch u will lose performance most likely cos lack of back pressure! keep it at 2 1/4 - 2 1/2 ", wat kind of lukey muffler is it ? get a hi flo cat as well, catalytic converters are so bad, mine is flanged and wen i take it off and put the pipe there it makes a huge difference.

there are other ways round buying a high flow cat, they are very restrictive and pratically useless after 60000k's neways. Apparently i read somewhere that a well tuned rb engine will still pass an emissions test without one? dont know how true that is.

my car came with a HKS 2 1/2 inch Super Drager exhaust, the extractors are "Coby" brand, ordered from www.partsco.com in New Zealand i think. I modified the final 2 into 1 section of the extractors to be 2 1/2 inch diameter to match my exhaust system.

    • Agreed, I've never seen a 260RS specific manual. As GTSBoy said it will mostly be stagea other than the engine loom https://www.hgeconsulting.com.au/stageaservicemanual.pdf
    • You'lll likely have to make do with R33 GTR for engine/tranny stuff, and Stagea for the body. I don't know that there's even been an actual diagram seen in the wild.
    • Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉
    • Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny
