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:

      Need AC Compressor for R32

      By silviaz · Posted

      Ah yep. I asked a auto electrician about getting a cheap rebuilt alternator vs a new one. He also said he used to it back in the day but it ended up costing similar to what a new one would and recommended getting a new one,.

      Will I Need A Retune After Cahanging My Catalytic Converter ?

      By silviaz · Posted

      Ah, to clarify if the car has already been tuned and has been modified and you want to go from a oem cat to a 100 cell or decat or vice versa.Are you saying that the car doesn't need to be tuned after a cat change if it's already been tuned?

      High temp brake fluid?

      By Komdotkom · Posted

      This has been covered a bazillion times but google wet boiling point vs dry. Motul is only good when it's fresh, once it absorbs moisture it gets pretty average very quickly. So as above, make sure you change it if you're going racing. I run the Endless brake fluid in mind, but only because a mate is a distributor and it's cheap. It's not quite as good as SRF but I'm running 380mm rotors on a Skyline so it's not like they get hot.

      Does 98ron contain ethanol?

      By Kinkstaah · Posted

      That's the thing, they still add it and it makes fuel cheaper, implying adding 10% of it drops the cost of 91 by what, 5c a liter? I remember when it was barely half the price of 98. Because you know, 85% of what is in the fuel is way cheaper than 91 fuel is by volume.

      Need AC Compressor for R32

      By GTSBoy · Posted

      Auto electricians that do repairs on automotive AC systems can source service kits. I don't know where they actually source them. I do know that there is one available for the R34 comp that I would need it for. If you have to pay someone to dismantle, clean and do needed repairs and fit kit contents, then you'd probably end up spending a good fraction of the cost of a new one. I would not be paying for that, because I would be doing it myself. My mechanic (bro-in-law) will happily source what is needed. Back in the day (like in the 80s and 90s), rebuilding an AC compressor was the standard approach, same as for starter motors, alternators, etc, because new replacements were v. expensive. After the China manufacturing boom and the rise of the disposable approach to everything, people just started throwing broken/worn stuff away and not rebuilding things.
