240Z_Master Posted March 24, 2009 Share Posted March 24, 2009 Anyone here have a good hookup for turbos? I'm looking for a GT3076R T3 Flanged, Internally Gated (Don't ask)... A/R probably .63. Thanks... I've searched far and wide but I figure if I could get the "Hybrid Z" discount Quote Link to comment Share on other sites More sharing options...
jc052685 Posted March 24, 2009 Share Posted March 24, 2009 I am selling my pretty much new internal wastegate for 5 bolt setup. Let me know, cause these things are like $100 new! Also have the actuator if you need that. Think they are $95 new. Make me some offers. Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted March 24, 2009 Author Share Posted March 24, 2009 I was looking something more built into the turbo housing... Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted March 24, 2009 Share Posted March 24, 2009 I think THIS would be your best bet for an internal wastegate - I plan on using it, and Hughdogz is already using it...http://www.atpturbo.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=ATP-WGT-023&Category_Code=WGT1 Quote Link to comment Share on other sites More sharing options...
boardkid280z Posted March 24, 2009 Share Posted March 24, 2009 What's this, Brad, the pic he posted or JC's thing, or something else, did you forget a link? Quote Link to comment Share on other sites More sharing options...

boardkid280z Posted March 24, 2009 Share Posted March 24, 2009 Here is a link to a thread where we discussed the UIW: http://forums.hybridz.org/showthread.php?t=144403&highlight=ultimate+wastegate http://www.atpturbo.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=ATP-WGT-023&Category_Code=WGT1 I also found this ebay auction: http://cgi.ebay.com/ebaymotors/Garrett-V-Band-Adapter-GT25R-GT28R-GT30R-WG-5-BOLTS-VB_W0QQitemZ160312405579QQihZ006QQcategoryZ33742QQssPageNameZWD1VQQrdZ1QQcmdZViewItemQQ_trksidZp1638Q2em118Q2el1247 They list it as only being for the Garrett GT series turbos, GT25-30, but I don't see why it wouldn't work on any turbo with the 5 bolt Ford style exhaust housing.

JustinOlson Posted March 24, 2009 Share Posted March 24, 2009 yoparts.com is the cheapest I've found. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted March 25, 2009 Share Posted March 25, 2009 THey say it is for any exhaust housig that has the 5 bolt Ford style exhaust housing. Supposedly it can handle the GT series turbos, but that may only be at high boost - not low boost - too much to bypass... Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted March 25, 2009 Author Share Posted March 25, 2009 I'm a fan of the one I posted because it has a divided flange to keep the surge down from the wastegate to the exhaust wheel. Anyone agree? This still doesn't answer my question if anyone knows any hookups for Garrett Turbos. Quote Link to comment Share on other sites More sharing options...

Anyone agree? This still doesn't answer my question if anyone knows any hookups for Garrett Turbos. Hehe, sorry for threadja... I mean sidetracking your thread. I found this site when I was looking around for info on Garrett's internally gated GT30Rs. Looks like a pretty good deal, compared to other places. $1200+$125(I.W.) http://www.cimotorsports.net/motor-sport-products/garrett-gt3076r-turbocharger.html I don't know if there any distributors who give HybridZers discounts on those, especially if you're looking for a genuine Garrett turbo. Cool flange, I guess you'll be making you're own downpipe with that exhaust housing. How far down will you reintroduce the wastegate gas? I have seen them put back in anywhere from 3 inches to 3 feet down from the turbo. With that adapter, you could make your own divorced downpipe and I've seen them where people reintroduce the wastegate exhaust 2 feet down from the turbo, some more, some less. Farther from the turbo, the gas is less turbulent and the reintroduction causes less backpressure increase. I believe this is what you were interested in. Something like this: (originally posted by jgkurz) But of course without the external wastegate. Here are a couple of threads I found about downpipes with wastegate piping and internal vs external discussions: http://forums.hybridz.org/showthread.php?t=125955&highlight=downpipe+bolt http://forums.hybridz.org/showthread.php?t=136938&highlight=downpipe+bolt I would say I would agree with your approach on keeping the wastegate gases away from the turbine exducer to improve flow, that is the one thing I am concerned with on the Ultimate Internal Wastegate that Brad and I were talking about. You're choice does seem to address that issue, and I assume it would flow more without that additional turbulence. I wonder if the size of the wastegate hole is any different.

kiwi303 Posted March 25, 2009 Share Posted March 25, 2009 I wonder if as an additional turbulence reducer, if having the waste gas pipe join the downpipe where the pipe sizes up by at least the area of the waste gas pipe? say a 2.5" tubo exit, and the waste pipe joins at an expansion where the downpipe goes up to 2.75", on it's way to a 3" exhaust/muffler system?

It seems like that would have a beneficial effect on exhaust flow. The turbine outlet (on this setup) is 3" though, so you'd have to step up to 3.5" or 4" to follow your line of reasoning. (3" is (30")^2 and 2" is (20")^2, so add those two and you get (50")^2, where 4" tubing is only (40")^2). I would be curious to see what gains you might get from having a 3" downpipe for 2 feet and then increasing to 4" as you reintroduce the wastegate gas. Compared to 3" all the way back with WG gas reintroduction at the same 2ft point. I know 4" seems big, but I'm pretty sure over 300hp, you would notice a difference and get some gain by increasing the exhaust size. And back to the original topic, check this page on Garrett's website that will give you a list of their distributors: http://www.turbobygarrett.com/turbobygarrett/jsp/SearchDistributor.jsp Quote Link to comment Share on other sites More sharing options...
