2nd generation RX-7's / TII How much is it worth?
July 07, 2008, 10:56:45 PM
Oh no don\'t get me wrong the FC is much cooler, but they are similar power, similar size/weight/shape, both FR, both Jap, both same age, and were I guess similar prices when new. Therefoe just logic to compare the two together :)

I would have thought £2k would be a good fair price for that car assuming it all worked OK etc :D FCs are equivalent to s13 200sx Nissans really, they are the competition, and they only fetch around £1200 when in VGC and minor unchav mods, I don\'t see the FC\'s being worth a fat lot more than that IMO.

2nd generation RX-7's / Absolutely Gutted

Absoloute wounder, as others have said you could\'ve been a gonner so be thankful for that! The sad thing is that even with a good insurance payout it\'s not going to pay you for all the time and effort and heart and sould you\'ve put into a restoration :(

Hope it works out well.

In the mean time... CRASH PICS! [/nosey].

It\'s true though. Don\'t put a loud exhaust on a rotary twin turbo sports car if you are worried about the neighbours ;)

You could just pootle a small way down the road away from your house if you think you\'re disturbing them.

That first gen looks good to be honest, and a good price for that spec/condition! I don\'t have any money/space at the moment, this thread was intended to give me some ideas, and I now have some. I will searchy search search and see what I come up with.

Cheers guys :)

No don\'t think you\'re putting me off, I havn\'t been "on" yet. I just wanted some ideas as to what to do. By the sounds of it then the PP is out of the window at the moment, always could look into it when I\'m feeling a little flusher or happen to have several spares lying around :D

What sort of mods would you recommend me to look into, and what sort of engine would you recommend trying to find for a play about with, mullins?

Like I\'ve said, I\'m not after a fast car, just something fun and fruity that I can rev and have fun in :D

Haha, I thought the MPG/PP relationship might not be a good one :(

If I can machine a housing myself then why not cheap? (I\'m not arguing, just wondering)

I was just saying 20k would be good, I know it\'s not possible I don\'t honestly think I could build a 20k rpm engine! Lol. I was just saying that I don\'t mind revvy engines at all :)
#8
Ah right, I\'ll do some more research into this then. If you could get me an idea as to MPG and I can decide whether the screaming 250bhp is worth the heart attack or whether I should just tickle the ports and be happy with 160-170bhp and less death-inducing economy haha.
#9
How dodgy is the MPG, ballpark figure? And what is it you mean about it being high up the housing? Doesn\'t this have an affect on the timing, ie the same as making the valve timing more advanced?
#10
Thanks for that, pretty much what I thought then. Anything stopping me making a comparitively small P/P which is just a more effecient version of an extended port? Getting rid of that pesky 90deg corner ;)

I know what you meant by overlap, but cheers for clearing that up :D

As long as I can get 25mpg on a motorway? Or is even that being too hopeful?

By your last post are you recommending a turbo\'d engine? I don\'t want a fast car, just something quick enough and fun to drive :D I have pretty much no money so would be trying to do everything possible for free by mates/myself etc, turbo\'s are another expense I can do without for now.

I don\'t mind high up power, I would like it to rev to 20k if possible, I don\'t mind working it. My BMW is fun because it has a million torques at 0rpm but would like something with no torque and screaming horsepower.

I thought about that small peripheral port theory, would a peripheral port of medium size (whatever that might be) be more efficient than a side port (or whatever it\'s called) of similar size? ie - would it use less fuel/harm the engine less/be more driveable, than an extended side port? Surely drawing the air/fuel in on the centre of the combustion chamber from a nice smooth intake port must make the engine happier than getting it from the crummy crushed up port in the sides (sorry not sure what you would call a "normal" port).

Thanks again for the info Grizzly, making me happy happy happy.

Hmm, just read into peripheral porting and I think despite the rediculous power to be had, and despite the fact I\'d love to have a car so savage it doesn\'t idle and you have to rev off the clock to pull off from the lights, I think I\'d probably get ass-raped for petrol and I\'d rather not do this to be honest! It seems that an extended or bridge ported motor might be a bit more suitable, and according to one site I just visited this is good for 200bhp? 200bhp would be plenty for me, as long as it had some kind of torque!

If the 0-60 would be below 7.5seconds, then perfect, I\'m not after a "fast" car, just something very fun to drive and useable every day when it hopefully won\'t be blown up :(
#13
never really been a fan of the first gens :( and would have thought they\'d be more expensive too? Ah I\'ll look into them too.

Cheers for the info on P/P, 250bhp!!! Holy crap that\'s loads! Hahaha if I got 250bhp in an FC then I would be happy. Will check out some aus forums yeah.

Thanks for advice :)

Thanks for the reply.

I am an apprentice at Rolls-Royce, was trained basic engineering skills, and am doing a degree in manufacturing engineering, I am only working the the lab but they train us the same at the start. I have a keen engineering mind though so would like the task of making something.

I will do some searching about the P/P which I assume is peripheral port? I will search some about this then see what other questions I might have.

I am aware of them not having a lot of torque. I would like to get an FC, then strip off any unnecessary stuff like rear wiper/motor, under-carpet sound deadening, any silly heavy trim or electric mirrors, would remove sunroof etc but would rather not go too extreme unlike my BMW.

I hear that the FC is about 1300kgs, so without an A/C, or emissions bumf, and all the bits of trim removed that I could, no ABS if fitted, no luxuries basically, I would have hoped to get to around 1200kgs, although before I heard FC\'s were so heavy I would have aimed for 1000kgs.

At 1200kgs, I would be wanting about 140lbft minimum, but preferably more.

The car would see the track, but would be a drift car mainly. Welded diff, mods to increase steering lock if possible, and some nice stiff coilovers. Drifting commands a lot of power but I don\'t see the point and enjoy the task of drifting cars with not much power since it is much more rewarding. My first drift car was a 2.0 Sierra and rather than buying it back, I thought I\'d just go for something a bit different like an FC, and since I love them - it makes perfect sense! :D

Hi all,

I currently do not own any Mazda, but reaaally have love for the RX\'s (hense me being here!). I will not have the funds/space for 2 cars for maybe a year at most, hopefully, but when I do I want to get an FC to tool about in on the roads with occasional track use. I am into drifting but already have a pretty sorted e28 BMW which is my main baby, but I want another car to use on the roads so would be keeping most of the interior and won\'t be taking it quite as far as my BMW to keep it "comfortable" whatever that word means.

Anyhoo, I should have space in my new house to do a bench build of an engine, and rather than making a BMW engine I figured it would be very useful to get a rotary engine to play with and rebuild how I want with the intention of then buying a car and putting my sweet engine into it. I used to raise my nose at the thought of an NA RX, but recently I\'ve really gotten into the idea of a revvy, kinda-gutless engine that sounds as sexual as a rotary, in a fairly lightweight and fun chassis.

I was wondering, after taking a quick look around ebay, what sort of engine you guys would recommend for a cheap as possible but still good rebuild? I don\'t want to completely throw economy to the wind but I understand whatever I do won\'t be frugle (my BMW is a 3.5 anyway!), I don\'t want to buy all sorts of fancy bits if I can help it since I\'m pretty poor, and I want it NA!

What engine codes should I be looking for, 12a, 13b whatever I\'m not really up on what I would benefit from getting, carb? EFI? Early? Late? Completely toast but free, or pay £50-100 and get one that isn\'t too far gone? Where\'s the best places for rebuild kits that I can fit myself etc?

Any advice/comments would be gratefully received, also, what sort of mods (preferably free or cheap!) could I do to improve torque and power between 4k - 9k or however high I could get it to rev? I want to be able to spin the wheels in 3rd round corners and have some tractability so don\'t want it to just have a million horses at a million rpm, I want some power from half way down the rev-range at least ideally.

If you could recommend some search terms that I could use then I will glady trawl through, but at the moment I\'m not really sure what even to be looking for!

Cheers!

Mike
