after removing the rear blades from my gtr turbos after only 700 km at 1 bar

thought that maybe a pair of s13 sr20 turbos(they supplly 170 rwkw pretty easy easch) ... which are cheap and have the same manifold pattern should go onto a gtr motor..

has anyone done it or are they too big for the gtr motor to spin

is it just a waste of time in the end???

and does anyone have a sr20 turbo floating around to see if it fits????

The dump pipe bolts are different between a t25g and gtr turbo, also t25g's aren't good at all

in fact they shit

and for the extra lag you'll receive from running 2L turbos on an effectively 1.3L pumpage, it's not worth the time and money

Is your engine actually alright?

I mean, in most cases I have seen where a GTR turbo has blown the ceramic wheel.. there are signs of ceramic in the bore.

Need to get the mini camera out and check it before planning anything alse.. full rebuild may have you saving a bit more :P

How can it get sucked back in thru the exhaust valve. When the exhaust valve is open the piston is moving up the bore diplacing the burnt gases. When the inlet valves are open the piston is moving down the bore suckling in the fuel/air mix.

So i doubt that something in the exhaust will get sucked into the engine...could be wrong though

don't know mate... the more i think about something, the more I can convince myself that this may be the case lol...

I don't know if this is the case, but with intake / exhaust cam overlap, a small amount of exhaust could be 'sucked' back in?? Therfore, if turbo goes kaput, part of ceramic wheel could be sucked back in?

I don't know - like I said someone on the forums said this and I was sceptical as well

Hi guys, I have seen 8 X RB's with ceramic turbine failure, 2 X GTR's, 3 X R33 GTST's, 2 X R32 GTST's and 1 X R34 GTT and none of them had any ceramic anywhere other than in the cat. There wasn't any in the turbine cover or in the dump or in the engine pipe, it was all in the front of the cat. Blown there by ~200 cubic metres per second of ~600 degrees celsius exhaust gas, that's better than my Stihl leaf blower. :wassup:

Maybe if you were spinning at the time and the engine turned backwards, you might get some sucked up into the manifold. Of if you where starting the engine at exactly the time the ceramic failed and it coughed and ran backwards. :headspin:

I don't think so, Tim :rofl:

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      RB26DETT Sketchy boost mod?

      By Duncan · Posted

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.

      boost source Size Garrett gt28 gen2

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
