stony Posted November 19, 2012 Share Posted November 19, 2012 Dont think this has been covered. Other then the premade kits, what turbos will bolt up to the rb26 exhaust manifolds. Pics of the turbos installed would be awesome. Whats the biggest you have ever seen on stock manifolds? Quote Link to comment Share on other sites More sharing options...
ZT-R Posted November 19, 2012 Share Posted November 19, 2012 Don't think you would need much more than the gtx28 series... Quote Link to comment Share on other sites More sharing options...
rayaapp2 Posted November 20, 2012 Share Posted November 20, 2012 I have a pair of rb26 manifolds. I suppose you are refering to physical space between the two manifolds? I have seen the stock manifolds ported out and larger turbos installed, but not to often. There is a ton of extra meat inside the port at the turbo flange. Im guessing its there to keep velocity up, but It apears to be one of the points where Nissan was trying to pull power back on these engines as far as I can tell. I ran across a Greddy or HKS display somewhere on the internet where they had fitted some larger Turbos on a mockup RB26 with stock manifolds. I use to save pictures like that, but my personal server crashed about a year ago and I have never gotten around to trying to recover that data... and I know I saved the pictures. I believe it was at one of the Japanese Car shows back around 2010ish that had the display. Sorry I know thats not much help. Quote Link to comment Share on other sites More sharing options...
stony Posted November 20, 2012 Author Share Posted November 20, 2012 Yea exactly my thoughts. The stock manifolds can be ported to match alot of turbos as long as the flange pattern is the same. Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted November 20, 2012 Share Posted November 20, 2012 We put my GT2876r's on the stock cast manifolds, just to see if they would fit ... They did. Quote Link to comment Share on other sites More sharing options...

stony Posted November 20, 2012 Author Share Posted November 20, 2012 Joel are these the turbos your talking about? These are GT2876r's? And they fit the manifolds? Did they fit in the car? Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted November 20, 2012 Share Posted November 20, 2012 Did you snap any pics with them installed? James Thagard did. I have the pic somewhere, and will look for it... Quote Link to comment Share on other sites More sharing options...

stony Posted November 21, 2012 Author Share Posted November 21, 2012 SO joel, If they fit why did you go with the top mount custom manifold? Were there other problems with fitment maybe with a downpipe? Im considering this to move all the hot stuff away from stuff that dosnt need to get hot ;> Quote Link to comment Share on other sites More sharing options...
stony Posted November 21, 2012 Author Share Posted November 21, 2012 Joel, Have you dyno'd your car with those turbos? i'd be curious to see where the power comes on at. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted November 21, 2012 Share Posted November 21, 2012 Pretty late i would imagine. Stony, Can you not fit a 3" dp down the hole? i fit a 4" down there with plenty of room. Even put a flex pipe in it so really its 5" od right above the frame rail area.... Quote Link to comment Share on other sites More sharing options...
stony Posted November 21, 2012 Author Share Posted November 21, 2012 I'm going to try eventually, I have a mid plate that mounts to the frame rails and it pretty much blocks off any passage for exhaust. right now it passes out the firewall just behind the left front tire.

Fairlady240Z Posted June 16, 2013 Share Posted June 16, 2013 I purchased the Tomei arms 8260 turbo kit. the kit provides all the water and oil cooling lines, gaskets complete direct bolt on replacement. The turbo's are rated @ 650 hp. Cost about $2800.00 shipping included. Quote Link to comment Share on other sites More sharing options...
