about 13.6 or 13.8 i cant exactly remember.

[jazza08]

damn... that means its faster than an R34 GT-T (14.2) and a Supra TT (13.9)... Im guessin becoz its so much lighter ay?? Interestin!

Anyone else debate that? Or is that pretty much spot on

are you referring to the FC or FD? ...

[calvintys]

kkekekek.... Rx7 sure a is a great car BUT

1. The petrol WIll KILL YOU,,, it drink like hell...If you are rich then is ok but again if you only use it for race then it also should be fine but if you want to use it for daily drive ... good luck.

2.Rotory engine... need to be rebuilt every 60K if i am correct not very sure but is somewhere around it.

3.DOes not have much space in it.

4.Handling if your KW is too high let say somewhere arund 300kw.. Good luck with your car cause you need skill to drive it..... Alot and alot of story about it car been crash before of KW,.,,, and also one of them is my friend/

Good thing about it is.

1. look nice and great

2. cheap in oversea, i am not sure about here

3. For drag in superb car.

Hope this will help

[calvintys]

wait the minute ,,, i am saying about the INfini .... not the savana .,.. i think infini is the current one

[Staunch]

im pretty sure that the R34 GTR does close to 13 flat...I have a clip of a 33 GTR and an RX7 dragging, GTR wins with ease, pro dirvers in japan too.

Ummm....

calvintys you really have no idea what you're talking about do you? After all, you said they need a rebuild every 60k.... the car im driving around hasnt had one, but it is due for a double rebuild :Oops:

Skyline will have more room, and why wouldn't it - they're a big sportscar.

Any 300kw car will be a handful in most peoples hands.

You need fuel for horsepower, simple as that - a well tuned rotor will be on par with a RB25 for fuel consumption.

If you're worried about the anything, the standard twin turbo setup in the FD (3rd generation) 1992+ onwards was a bit unreliable with oil starvation issues. Apart from that theyre a reliable quick sexy car. Treat it well and it will treat you well. Not blindingly quick out of the box but respond very well to modification.

Very interestin!!!

Im not really looking for space... bein a 17 year old boy n all lol. Im lookin for quick n sexy ... Arent we all

Its light.. so it handles well and is quick off the line, as ive read. And thats what im lookin for, somethin light, sexy, quick with handling. Thats the only reason Im alil weary of a Skyline because Its abit to big for my liking, love da look etc But the size just makes me like an Rx7 abit more...

No it won't. The rotary works similar to a 2 stroke, so it has twice the inlet cycles of a 4 stroke. Similar to how a turbo car will always drink a little bit more fuel than its NA equivalent on the highway, because at highway speeds you're on a bit of boost and this will always necessitate a bit more fuel no matter how well you tune it. Also don't forget that rotaries need to rev pretty high to make power, which means more fuel is required.

Even the current generation RX8 which is meant to be the bees knees of rotary economy only gets 12.6L/100km in a "combined" economy run, for only 170kw of power at the flywheel. My R33 gets over 220kw at the wheels (so what, 300 at the fly?) and I get 10.5L/100km on the freeway and 13.5-14L/100km around town so I imagine around the same for "combined". And this is just the base map of a PowerFC, I expect it to improve after tuning (especially the highway economy). The R33 is heavier, too.

I agree with the rest of your post though. Rotary engine reliability issues are a myth. I think it comes from the old days where people would do a massive bridgeport to boost the power up, and this could interfere with reliability. But these days you just whack a bigass turbo on and there aren't any issues really. They probably take turbos better than any other type of engine.

Damn, is everybody reading my mind??? I've been considering an '89 RX-7 cab import as a good cruiser before committing to a skyline. Anybody got any experience with the cabriolet?

[DJ984]

Similar to how a turbo car will always drink a little bit more fuel than its NA equivalent on the highway, because at highway speeds you're on a bit of boost

But when you cruise off-boost then your actually MORE efficient than your NA counter part due to the different vacuum ratio's in the engine.... That's why whenever i go from syd-newcastle and back i basically run off the oil on the road ... don't use boost and the petrol guage doesn't budge! (on the freeway) ... and no, my guage is not faulty either...people who understand the mechanics will know what i'm trying to say in my poor wording... lol

if you wanna get an FC, go for the series 4 or 5 and preferably 89 model onwards becos the overflooding petrol is solved from that time onwards. Its a very nice car with a great sports shape but the interior is kinda crappy as compared to a skyline. there;s ALOT of potential when it comes to modifications and the 13B engine responses very well to it.

my 2 cents.

[JimX]

DJ984, I'm not sure how that works. Just because you still have negative plenum pressure doesn't mean the turbo isn't doing anything. And on top of everything else the exhaust still has to push past the turbine which reduces the engine's efficiency slightly.

Ive known a fair amount of ppl who have bought rotors, and honestly they sell them after 3 months. The reliability issue IS there, but its not as bad as some make it out to be.

Fuel is a complete bitch on them. Ive seen $40 of fuel burnt in one day just driving around the burb's

Buy a skyline, i find them a much nicer car to drive, and they sure dont lack in power.

[JimX]

Ryan D, what rotors did they buy? Were they bridgeported? And how old? It could just be that performance car from the 80's = flogged to shithouse. I know a couple of people with 80's and 90's RX7's that are still running on the original engine and well over 100k km. But they probably drive more sensibly than I do
