I have a feeling that this particular turbo have steel inlet wheel.

Same ceramic exhaust wheel.

I would say that the boost and power levels would be close enough to the same.

I think on the series II R34, there was a 20nm hike in torque, but saem 206kw power rating.

BASS OUT

I wouldn't think so.

I'd say that there were either engineering computations that said the nylon compressor wouldn't suit the slightly raised torque, or they didn't want to do another build of the turbos because they were running the model out.

I thought that Japan had a max allowable output of 206kw by law, and everything was claimed to be 206 when in actual fact they were putting out more (closer to 220kw in series 3 GTT)

First they had the engine capacity restriction, until a clever guy invented the turbo, then they had a max power output to combat that. Next thing you'll prolly see is all carbon fibre or plastic panels to get a better power/weight ratio! =-D

the 206kW isn't a law, its more of an unspoken agreement...

its like in golf, how you don't walk on someone's line on the green.. there's no law, its respect for the othere players game

cf respecting other car companies overall car quality rather than just their power output

And on the topic, i have an R33 series 2 turbo with 45v2 on the side, and it definately has the nylon compressor wheel...

99% sure they are the same mate, differences between the RB25DET and RB25DET Neo are all internal not external, so parts like that should be a straight match.

Can anyone else with a bit more knowledge confirm that?

Bump. I would like a confirmation of the above, as I need to have my manifold > turbo bolts done, and workshop suggested just going straight to drilling+retapping them which will be expensive. My other option is a NEO exhaust manifold off a mate for cheap, low kms. Will it be a direct replacement for my s1 R33 RB25 engine?

Also, how much are they roughly worth second hand for below 50,000kms?

Thanks

not sure if its ba bf fg fgt

but I'm havin bad luck eit​her way motherf**kers :

The car I bought had bl​own the turbo and didnt get around to fittin the f6 one and bought an f6 car himself & lost interest.

​SO:

I got turbo all hooked up (f6), dump made, lines done then start up and oil in entry and exit of turbo and lots of smoke. FK

So I buy a r33 turbo for rego and cut/ weld its dump to suit and redo the lines and again FK I get oil out the dump this time... FK but getting money bak

So this arvy I'm getting an ​r34 turbo for reg, taken off a running r34 to upgrade. Temporarily I will run this until I sell/ rebuild & sell or rebuild and use this gt35.

this will be the 3rd turbo bolted to it in under 2 weeks lol.

Hi all I'm doing a little research as I'm after stock reliability for my track car so going back to standard Nissan turbo on my r32 rb25det s2 from my aftermarket set up.

 

read this post and others -

what id love to know is what is the 'best' standard Nissan turbo to use.

i recently bought an Op6 then realised it has the single blade nylon compressor wheel (45v1) and rear steel wheel (shown as have having 6 point hex nut). From other posts I see this turbo is good up to 12psi.

Now this week mate wants to sell me his op6 turbo for a decent price - this turbo appears to have twin blade (metal) compressor wheel and 45v3 on it. What boost would this turbo be rated too -

overall which turbo is better??

No OP6 turbo has the bit I bolded above.  Regardless, any Nissan/Hitachi turbo with either or both of ceramic rear or plastic compressor should be run at more than 12 psi.  Not that this is the "limit".....they're just increasingly likely to explode as you wind the boost up and below 12 psi it's a bit less likely than it is above 12 psi.  Some die at 7 psi.

Realistically, there is no such thing as "stock reliability" when talking about these turbos.  Especially when talking about a track car.  That is the place where you will certainly kill them.

That's how it looks when you run the turbo over 12PSI ..

Never found the turbine wheel I guess it went straight through the exhaust.

The compressor is nylon btw. (this coming off an 1998 S2)

 

Actually I was running this turbo at 14PSI for a while and thought I was lucky.

But when I went to the drag strip and floored it went on the first run :(

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
