i also think the 2-3" jump is a bit dodge. but to answer your question, i have a cheapo R33 dump pipe on my s2, just had to change the angle of the long straight piece so it met up with the cat ok. that flexi section may help with this, i cant remember how much i had to change the angle but those flexi pieces only bend slightly.

excuse me if this seems like a stupid question, but i realise everyone wants the dump and front pipe to make up the "turbo back" system, but i was just wondering what about extractors???? does anyone have them or are they no real improvement once you've got the dump pipe hanging off the turbo?

just curious ppls

cheers, Bradd

you mean an exhaust manifold.

maybe one day I'll grab a decent brand name stainless steel mig welded 2nd hand item off ebay (around $450US)

same goes for the intake manifold, one day would like a Greddy plenum, rerouting the fmic as neccesary

Hi all,

Just wondering, of those of you that have fitted a large hi-flow cat' (the round stainless style with 3" flanges and 4" or 5" body), how close does your cat' sit to the ground? My ride height is currently about 395mm centre to guards and I already have too little clearance there for my liking. My cat' is the lowest point on the car. If I go any lower, even 20 or 30mm, I fear I might collect speed humps!

cheers mate, so the standard exhaust manifolds are pretty good up to say 300kw or so??? like you wouldn't put one on unless you were putting a custom plenum on as well?

a turbo charged car does not have the "extractors" that a naturally aspirated car has, on an NA car, you have the head, the extracters/headers(on a 4banger they are 4-2-1 or 4-1) then the rest of the exhaust.

on a turbo car you have the exhaust manifold hanging off of the head, with the turbo on that, then from the exhaust of the turbo- the first bit is called the dump or down pipe, then from there too the cat is the "front" pipe, then your cat, then the catback system which ideally has a midmuffler then the rear muffler

cool thanks for clearing that up for me ryan, just wasn't sure how it all worked with the "turbo back" system

now time for a dump/front pipe, is it better to get a dump and front in one piece or to get the spilt dump pipe with a separate front pipe?

personally I would go a proper 3" bellmouth, not the chinese spilt's...

yeh thats what i thought too, just lookin at a couple on ebay, there's one that is a 3"bellmouth design dump and front pipe in one for a 33 (which means it should fit my S2 ) i dont see what the advantage is of having a split dump pipe anyways, its all going into one pipe anyways?? :S

Greg from GKtech is a champ too, but i wasn't impressed with his RB product.

      R34 GT-T cycling ABS pump

      The team at OBD2 Australia are pretty good, shoot them an email and ask them. I've dealt with them before for work stuff. I'd be shocked if it didn't work, so long as Consult can activate the ABS. But you might need to use KLine for it which would be the stopper, as I don't think that piece does KLine comms.

      Yeah and hence my ghetto way of slamming the brakes, get the ABS to cycle, rebleed seems to be a sensible workaround.

      Hey! Happy to help. Nothing inherently wrong with the adapter, it's more so with Brett Collins himself. He gave me a lot of incorrect information when I was in contact with him and was extremely rude when I challenged him. He stated I could not use any aftermarket twin plate clutches except for his own, not to use the dush shield, bla bla bla and it was all BS.  Collins stated to cut roughly 14mm's off the housing, I took off 15mm to make room for the dust shield. I would confirm with whatever adapter manufacturer you're using.

      33 GTR Broken front wheel knuckle

      There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.

      Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.
