hey guys.

this has run through my head a bit, and i dont know if it would technically work.

i have 2 r32/33gtr rb26 turbos, and 2 r34gtt turbos, i have been playing around with them and just wanted to know if the front wheel and housing is too large to throw onto the rb26 turbos.

the r34 comp wheel fits on the rb26 turbos and so does the housing.

the rb26 rear housing is .48 correct? and the r34 front is .54? waste of time or try it and see how it goes?

only problem is if i do try it, one of the r34 rb25 turbos is plastic wheel and the other one is a steel wheel, two different versions of the rb25.

thx

If you are even considering this, I suggest that you never touch a turbo again, and let a mechanic do any work from now and on.

Haha bit harsh nothing wrong with playing turbos just be prepared to break them or fork out for s engine build. I did it broke every turbo haha but that was on a 20 so 400 to replace

hmmm, indeed. i just wanted to know how it would work out. i have no problems re building stuff or modding close to anything. i guess if you pump in more air than you can flow out, it might become a bottleneck.... i should have really thought about that before posting this.

A turbo spins at up to 150,000 rpm. Do you think rebuilding it yourself is a good idea with regards to balancing, etc.

Plus is it worth the risk destroying a rb26 just to save a couple of hundred and "experiment" on things that garret has already spent millions on doing?

There are plenty of tested and proven turbos in the dyno results thread.

I've also got a pair of genuine HKS 2530s for sale that have about 5,000kms on them. Rear housings are HPC'd too. Lol.

Sorry if I sounded harsh - just seen some really stupid things posted lately.

nah, all good. no trouble there. its a forum for a reason :D yeah i know turbos spin that fast, its being rebuilt with the n1 internals, so i was wondering if i could use the front end of the rb25's. either way, no point. if the frnt flows more than the rear can handle, not to mention hot air after combustion expands even more. i swear to god i had a blonde moment........ *facepalm*

Good to keep the brain active.

And its by doing some stupid experiments that some weird and wonderful creations pop up.

If you have the time, and parts, give it a try.

I don't think Nissan designed the 300zx airflow meters for the 26, but what do you know, a small wiring mod, and they work.

If you do try it eventually, good luck, and keep us posted.

      RB26 block, rb26 head

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
