why the downgrade?

well if you built a 13b and squice 412 hp to the wheels, and on the last dino pull it blows up, and the apex seal takes your $1500 turbo on the way out. you will think twice to do it again don you think...

Yeah, RB26's usually do it the other way around... Blow the turbo and take the motor out...

What is the car being used for? As the RB26 will be alot heavier up front destroying a fair bit of weight distribution in the RX7...

I was meaning weight overall.

The RB26 has to be at least double, if not triple the weight a 13B.

Might help though with drifting, more front end grip. Circuit racing would be a different story though.

Have you weighed both motors up at all?

Surely though a 300rwkw rotor shouldn't just "die" if built right?

Few friends of mine have had reasonable powered rotaries without much of a drama.

What about SR20? That idea cross your minds? Would be lighter and then less need for more power :nyaanyaa:

Yeah, RB26's usually do it the other way around... Blow the turbo and take the motor out...

lol that :nyaanyaa:

If using the stockers of course... Which i pray he isn't...

Is that a comment based on myth or fact? :nyaanyaa:

As i said, i know a fair few rotor owners... it's nowhere near as bad as everyone "thinks" which is just based on rumour among the piston crew predominately.

Add to the fact rotor rebuilds are nothing of the expense that is a RB26.

I've heard of more RB26's letting go than rotaries among all the people i know... which is an interesting thing i think :nyaanyaa:

the point is that it "happened" and now im up to better and grater things. live alone challenging, there for sr20 is out of the question, its bean done numerous times. and a FC/RB26 not that i now of...

Same here... And that's if you EXCLUDE Duncan from that list...

PS: I hope you've fitted a winged and gated sump to that thing... Other wise I see it lasting around 1 drift meet...

When treated right, a Rotary will last well into the 200 000KM range. (Which is the same for most performance motors, yes your mums Dad's Uncle may have a commodore that has 450 000KM on it, but does it get revved to redline every day... No)

Edit: And by the sounds of it letting go... Sounds like it pinged... And that is one thing a rotary will instantly shit itself from... Detonation.

yep it was mi mistake. forgot to wrap the down pipe and premix so it was catastrophic failure. the back iron broke were all do... and the center one pushed the coolant seal into the passage. + the rotor and rotor housing and turbo GT35R lol im done with them for now.

Yeah but wouldn't this be because people (making an assumption) think that rb's can take a beating... and they know for fact! that a rotary will be more fragile under load hence why the 26's are blowing quicker in most cases because the driver will take more caution with the rotary and give the rb the beating of its lifetime lol

you get what I'm saying?

Have you seen rotary guys giving it a go? I have... They push just as hard as piston drivers do...

And the OP admitted his one letting go was a human error issue, not a mechanical flaw...

Yeah fair enough :nyaanyaa:

Although it's not the first RB26 into a FD :nyaanyaa:

One... if not two of the big Jap tune houses have a FD with a 26 (or at least had one hehe)

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
