after thinkin about the sunny gtir, i thought id find out alittle more about rx7's and supras, i know supras are a 3litre turbo, so i bet the mpg is appaling, i love the look of rx7s but **** scared of runnin costs and havin an engine rebuild

mpg is probably worse on the rx7

I had a Supra non-turbo. 220 bhp and big engine giving good low down torque. The power and the handling are superbly balanced giving good RWD fun. Very cheap to service in comparison with my STi for standard stuff although expensive if things go wrong due to it being an import.

Stuck a HKS Hyper Muffler back box on mine and it sounded as good as it looked.

I got 25-30MPG depending upon my driving.

I bought a low milage one and was my favourite car to date. Got an 02 STi now for family practicality, but still envy Supra drivers.

My opinion of course.

mpg on the RX7 is about 17mpg on a good day with sensible driving for the whole tank

Some very good cheap cars out there at the moment, theyre struggling to sell, Told you before best bet is to buy one thats already been rebuilt, saves you a packet, then the only other thing to worry about is the suspension bushes if its a pre 95 car

tonner_notts

im really tempted by one dave, you ever heard of transcars? its an import firm,
they offered me 8.5k on a px which is better than ill get anywhere.

as for the supra id like a tubo one, although i presume the mpg is alot worse

all turbo cars have adjustable fuel consumption controls, its called right foot planted = low consumption, right foot light = okay consumption.
(unless its the rx 7 where you will probably be changing gear at 8000rpm + )

davegtt

Yeah heard of Transcar. Not heard much about them though. To be honest though if your importing from Japan you dont know what your getting engine wise and your running a risk although I should imagine you'll be getting a decent warrenty so you should be OK

RX7's aren't as unreliable as people think...... they're unknown cos their a rotary so a lot of folk assume thier "evil" lol.

I had an RX8 and contemplated a 7 after it but a few things (seats / doors) put me off..

The RX7 you are talking about will most likely be the FD twin turbo version, this is the same engine as the RX8 (13b) only the ports are different, the MPG will be in the region of 17 no matter how you drive. This was one of the reasons i got rid of my rx8...

Around the 60k miles mark the rotor seals on the older twin turbo engines started to "perish" and as such compression was lost, this involves a rebuild which will cost in the region of £3k but after this is done you pretty much have a brand new engine, plus, if you take off the twin turbos and put in a single turbo you will hit 450hp no bother, they are absolute flying machines that are light, handle superb and redline at about 9500rpms...

If you buy one that has had a rebuild ensure its been done by a rotary specialist like Carl Hayward or something then you get a warranty and really don't have to worry about it.

For more info look on the Mazdarotary forum, lot of nice highly modified cars...

Apologies for the essay!
Chris

davegtt

Chris, redline at 9500rpm? no thanks.... think 8k is safe enough Tonner, this guy will accept 5k (probably a little less if you push him....) looks a real bargain, you want an RX7 then go take a gander. seems a bargain with the rebuild too

http://www.mazdarotaryclub.com/forum...ad.php?t=18793

tonner_notts

yes i like that car, seen it b4 on pistonheads, need to sell my car quick,
or need transcar to have a cheap good car in, which i think is unlikely as most of theres are about 8k,

What goes wrong with the bushes?

Branners

probably worth heading over to www.mkivsupra.net for more info on the supra. Its a 3.0 so its never going to be frugal but 24mpg on the motorway would be reasonable, possibly more if you just set the cruise and go. Very realible, no inherent design flaws and take a fair bit of abuse.

If I didnt have a supra I would have an RX7, both great cars.

My brother has a twin turbo vvti supra...

It's one hell of a beast which is extremely reliable with a virtually bomb proof engine...if you turn the boost up too far though the turbos as expected won't last so long.

As for parts, imports aren't a problem, he's always bought everything he needs from the local toyota dealer...

My mate did that on his Supra TT, he bought Envy hybrid twins to replace them but he's going big single conversion and looking for about 7-800 bhp. Expensive but fun hobby.

LOL, where to start....

mpg - if you do a lot of motorway cruising you might average the often quoted 17mpg, around town or making use of the right pedal will see you around the 10mpg mark.

single turbo conversion - think many thousand pounds, you can't simply drop in a large single, you'll need exhaust, fuel system, intercooler, ECU, etc. The more power the engine produces the less miles it will last. As Dave has said the redline is nowhere near 9.5k rpm, I've had mine up to 8.7k having raised the rev limit to 9k, but even on a ported engine power has peaked well before then.

As far as comparing one to a Supra, it really depends on how you plan to use the car. If you want a near bomb proof car and spend most of your time on the motorway then the Supra is a better choice. If you drive around on smooth A roads with associated twists and turns and enjoy the character building of niggling problems then the RX is better suited. Neither will be anything like cheap to run, but the Supra will be more reliable and return better mpg.

BTW, there really is no point in importing one from Japan, the UK market is on its knees as there have already been far too many imported into the UK.

rs125 - the bushes just wear out as with any car, but on an RX they are hideously expensive (think safely over a grand for a full set) so something to be aware of.

tonner_notts

a grand? that is alot

davegtt

yeah a grand.... not looking forward to my MOT next month, got an awful feeling they're gonna need replacing fingers crossed I'll be OK thou

tonner_notts

lol lets hope not dave, what do you think of the car you showed me dave? if im lookin at it should i get it checked over by a specialist?

tonner_notts

also what diffenrent models do they do? is the single turbo any good insurance only 800 quid and 1100 for twin turbo

DreXeL

I pretty much echo what the others have said about RX7's, changed my Scoob for one last year, and don't regret it one bit (dispite having to rebuild it due to water-seal failure, I did the rebuild myself), they are just awesome cars.

Go for one with a recent rebuild and there is no reason they should be unreliable if looked after.

I have a friend who owns a 6-speed Supra TT, I've driven it quite alot and compared to my Rex it just feels soggy and lardy. Great engine, very flexable with nice low and midrange grunt, but not as quick as my Rex (his car is ~380bhp, my rex is ~360).

As good a car as the Supra is, I would much rather have my Rex thankyou.

tonner_notts

yes i think im going to get one, just want a test drive or ride in one 1st to make sure, are there two types of twin turbo?

cong

definatly go for the rx7 doesnt take a genius to do the power to weight ratio! and the rx7 wins it everytime!

There were 3 generation of RX-7's over the years. The ones from the nineties were 3rd gens, which is what we have all been talking about. These came solely in twin turbo configuration. As with all cars the spec was tweaked over the years, so power goes from 255 up to 276 depending on year. Ultimately it doesn't make much difference which year you go for, but if you are really interested there are sites with specs kicking around out there on the internet (if you search on the MRC site linked to previously you should find something).

imi

I own a Supra TT so will only comment on that. Have never driven or owned a REX.

- Supra TT - 100% london driving 20mpg - in the motorway it gives me 28mpg
- Extremely reliable, bomb proof.
- Not too expensive for servicing, however you need to take it to a trustworthy specialist like any other supercar.
- Handling is amazing, very chuckable, amazing grip and loads of fun (on the Jspec one anyway, UK spec has a different suspension setup), Great drive on the motorway, in the city, A roads, B roads whatever.....
- Power / Torque - loads of power standard, if thats not enough then very easy to bring it upto 400-420bhp with very basic and simple mods.

DreXeL

I found it to be exactly the opposite compared to my Rex, it felt more like a GT than an out-and-out sports car. You can definately feel the extra weight of the Supra when chucking it about.

Don't get me wrong, I think they are great cars and as you say, they have bomb-proof reliablility, but to me they just don't feel as tight and nimble as a Rex.

JimmyMcIOM

I've driven both Supra TT and RX7 and would have a supra in the blink of an eye. Couple of reasons, rx7 is too smooth with not enough torque, supra is far more reliable and cheaper to run/insure. Also it has 4 seats. And it's very easy to get big power out of them whilst keeping the reliability.

davegtt

the rex has 4 seats? well mine did the last time I looked in the back might not be very useable but hey, who cares when your permanently driving sideways down the street

Tonner, If your interested me and a few guys from around the area are meeting up in Muston on Sunday (about 20minutes from nottingham on the A52east) if you fancy coming over and meeting us, I'll give you a blast in the motor on some well known roads, but be prepaired to be wanting a mazda and nothing else will do.....

Up to you but you know where we'll be... 1pm on Sunday Muston Gap - Muston.

flat4_ire

thats because its not as tight and nimble as the rx7, nobody is saying that man..thats obvious, the supra is a lot heavier..im looking for a supra myself at the moment, would like an rx7 too but afraid of reliabilty issues and i dont think theres any real specialists here in southern ireland..plus my friend has an rx7 with roll cage and when i sat innit i just felt like donkey kong in a go cart,im 6ft2 and pretty big, not a monster but def too big for an rx7 i reckon

davegtt

Hey Drexel, not had any knocks on the door for your adventurous driving around bristol yet?

DreXeL

I didn't say anyone was saying that, but the original poster wanted a comparison between the cars, I was just letting him now how they compare back to back.

Like I've already said, Supras are great cars, and I have alot of respect for them



PMSL, without wanting to tempt fate, no I haven't
