that was a theoretical statment, they may be. Personally i don't like the sound of rebuilding and engine <100,000km's so i'll never play with them. But i shouldn't actually say never becasue the do make huge power considering their displacement.

Tell her that it is a 2 storke engine (Even though it doesn't have any strokes), so in effect it'll use twice the fuel that a regular 1.3 litre 4 stroke engine does. It's also why they are rated at 2.6 litres when compaired to piston egines and why they make so much power from 1.3 litres.

told her that. she looked at me like id just asked her the square root of 16 billion.

theyre pretty average on fuel. lowest ive seen the consumption for one in town/suburbia (where she and most people will use it) was about 10l/100km, highest was in the 20's...

as for the rebuilding engines every 100,000km, very true for the older design engines (fd and older), more so when theyre boosted and modded, but not so true for the new peripheral port engines they use in the rx8, service life is a lot more generous.

... but its also a lot less exciting.

"lol"

:lol:

:D

:O

I thought that you couldn't type in the emoticoms but it must just be that there isn't one for :lol:

Oh it's 126491.10640673517327995574177731 by the way but i did use a calculator. :P

I would've thought closer to 3.9L

Knock yourself out on that thread... :D

on the topic if rotories, id love to have one of these;

with a 20b twin turbo itd rival both my old celsior and the 200 for fuel consumption, but itd be a great cruiser.

its the same old thread as every other rotang thread.

"rotors suck, why?"

cue jokes about busted seals and the rspca.

argument about why everything else a superior engine and that rotors sound like bad gay sex.

finish with something about an ls1.

i just saw the 3.9 litre bit but i think that is a crock, they only use 1 side of the rotor each power (Stroke) so they are only using the 1.3 litres. that's like saying that a 2 litre engine is really 4 litres because the pistons sweep 4 litres per full cycle.

Also that bit about gearing up the eccentric shaft 3 times to use regular gearboxes is also grasping at straws. They use a 3 times gear up because the rotor has 3 sides, so him saying that they could step it up to 6:1 then there would have to 6 sided rotor which would be huge.

uuuugh.

itunes just decided to purge 80gb of music from my ipod.

now for the tedious task of reloading all that music from about 12,000 different sources (3 hd's, and a couple hundred cd's...)

235's all round could work. but im not lowering it more. low enough as it is. srs. exhaust scrapes and front wheels scrub as it is.

lulwat? What are the wheel and tyre specs on the one in the pic?

Tuck the exhaust up and roll the front guards and maybe a slightly narrower tyre and you will be able to go lower to end up with the real shit fitment wise, or just pull your guards a bit so it reps flushness and doesn't look so cop-happy.

I have nothing against rotary engines, in fact I love them and the sound they make, but I have to agree with the whole 3.9L displacement argument as each rotor has 3 combustible sides to it for every one rotor revolution (not crank or eccentric shaft revolution).

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
