Anyone know much about the screamer dump pipes? How well they seal? I've heard they're reallllly leaky

many reports of them not sealing properly, and never sound as good as a true external gate.

also, it really is a pointless modification if only for the sound..

but it is your car so, your choice.

Alottttt of people running screamers and I haven't heard of anyone getting done for anything other than undue noise.. Even my old 25/30 with 4" turbo back with no mufflers just q cannon and screamer I didn't get done :-/

those shithouse dumps are just that, shithouse.

a better way would be to pull the turbo off, tack the internal flap shut and weld a pipe off the exhaust housing, and mount a gate off that, use a V band or 2 or 4 bolt gate no worries. absolute waste of time on a stock turbo but if its purely for sound, much better way to go, there is 1 or 2 decent chinese gates on the market, some of them are shockers.

I'd wait til you get your hands on a better turbo, even a high flow would be okay. then fiting a ex. gate off the exhuast housing wouldn't be quite as much as a waste of time, money and effort.

in other news I've organised a oven for saturday to paint all the bits for my datsun. prepped the front bar last yesterday, just need to prep the front guards and door, and spray them out. will sit the panels back on the car on sunday, except the bar, need to do a bit with motor so wont put the nose back on just yet. just about to go put wheels back on it so i can move the bugger about again.

this fine weather and daylight savings has boosted motivaton lol

What about a low mount with the fitting for a gate there already, and weld the internal gate shut on the stock turbo? Then I can get it high flowed later or go 3082r later. Really I just want the sound at the moment lol I miss gate :(

yeah you can run a ex gate provision off a stock manifold, but welding to cast is a little tricky, but can be done. there are a few places that could do it for you.

other option is to get a old HKS low mount cast manifold with 4 bolt gate provison. rareish, but work okay.

or get a custom manifold built with the gate provision built in. you'd be looking at around $850 min for something decent.

I have a stock manifold here, you could take that and get that modded, I would think you could do the whole thing for 2-300 bux with a cheap gate, just becareful which one you get.

the other end of the scale is to get say Ryan up at ulverstone (capel motorsports) to build you a manifold, he does fantastic work, on par with 6 boost. that will be around 850, then if you buy a genuine gate, say Tial 44 or 46 your going to be up for 1200ish by the time you've done gaskets studs and nuts etc.

I've got a stock manifold too if you want it.

DanialH in the other thread has a high mount external gate manifold for sale http://www.skylinesaustralia.com/forums/topic/374203-fs-brand-new-18x8-and-18x9-wheels-and-hks-2530-turbo/

I got AzCustom to make my high mount manifold and screamer and that was around the $1100 mark, sounds tough as nails though.

I've got a friend that got gate and screamer done on his stock cast manifold, cost like $120 for the guy to do it all, had the gate lying around lol. But was done properly (heating yhe manifold up to the right temp first and cooled down slowly). No eBay monsta high mounts then? :P

hypergear is starting to make his turbo's with dual gates, int and ext

you said you were thinking of a highflow, this will bolt on and use stock dump + have external gate

i had an ebay monsta high mount on my VL, i had to get it redrilled and it leaked like a siz but two gaskets and a whole heap of heatproof silicone and it was fiiiiiiine, well as fine as a bogan spec VL gets.

Who's your friend? i did one like that for someone a few months ago.

Well finally got Jacks parts painted yesterday so he can now get it all back together and hopefully leave me alone for a while lol. Anyway he wanted me to put the pic's up for him.

    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
