What's the Mid Night Club?
What's the Wangan Run?
And what on Earth is a 'Touge Monster'?

First of all I'm blaming Rogue86 here and Nik da Greek here for this. I was quite happy pootling along in my E36 328i and then summer kinda started and people got to updating their RX-7 threads and all of a sudden I remembered why I started driving E36s at all in the first place - a big compromise.

Maybe (but highly unlikely) you remember this thread? I used to own an RX-7, a UK model which had a mild bit of tuning and kept me pretty happy and before that we'd tried dailying a stock import RX-7 but it ended in tears when on an unseasonally wet Thursday in August my wife (then girlfriend) spun it across three lanes of the A3 during her commute. Life happened - my daughter arrived (then my son) we moved house a bunch of times and owning an RX-7 was deprioritised in favour of family life and cheap BMWs to fill the fun car void (mostly documented here).

Roll on six years and we've got the house and few extra quid and you guys remind me of the thing I'd forgotten I was missing, but all of a sudden I REALLY missed it.
A simple bit of man maths later and I had a budget and a mission. Blimey RX-7s have got a whole lot more expensive since 2010! I sold a low mileage super clean, stage 1 tuned UK model (one of 124 I believe) for £5200 back then. You can't get nothing for that these days! But also I'm not made of money either! I looked at importers but you couldn't really get what I wanted on my budget - basically something black with a single turbo conversion and a healthy engine.

I sat in wait and _eventually_ this came up biggrin

(picture from when I went to view it)

After an *amazing* test drive a deal was struck and a deposit left. An agonising couple of weeks went by while me an the seller sorted out documents and money and finally last night I got to pick it up!

So here's the pics taken on the drive home:












And then this morning once it was safely tucked in the garage:









So what did I actually buy? Well it's a 1997 RX-7 RZ Special Edition but it's a bit extra special because once upon a time a lovely person in Japan put a lot of love into the car and the spec list is pretty exhaustive:

Original RECARO RZ carbon fibre seats
MOMO Steering Wheel
Aluminium passenger footrest
rear bins not seats
A'PEXi Power FC ECU, Commander, boost controller and upgraded MAP sensor
HKS T04r single turbo conversion
HKS Turbo Timer
HKS Coil Leads
HKS Twin Spark ignition amplifier
Knight Sports WT Controller (controls the aux. fan)
Knight Sports V-mount radiator / intercooler
Knight Sports throttle body
Knight Sports vented bonnet
Knight Sports vented headlight cover
Knight Sports side skirts
Knight Sports bolt on wide arch kit
HKS coil leads
Greddy Type R wastegate
HPI Induction Kit
Front And Rear Strut Braces
SARD Fuel Pressure Regulator
Front Mounted Oil Cooler
Quantum coilovers
Trust exhaust manifold
Custom down-pipe
Straight-through 4in exhaust
Screamer pipe
Uprated Injectors
Some kind of (tight!) LSD
ARC Magic GT Carbon Fibre Rear Wing
Continental tyres
Competition race clutch (not really much fun)
Huge Brembo brakes (look a lot like late Evo brakes?)

The last owner had the manifold re-welded (it was blowing) and also got a confidence inspiring compression test done (7.5,7.3,7.3|7.7,7.5,7.4) that points to a recent rebuild, the owner before him (the guy who bought it as a fresh import last November) got the alloys refurbed and the new tyres as well as alignment /tracking.
Currently the car is running about 0.8bar of boost and has done about 4000km since it was imported.

So that spec makes me think the original enthusiast Japanese owner was definitely into his street or mountain racing - hence the allusions in the thread title (also I've been watching far too much Keiichi Tsuchiya on Hot Version lately).

The pictures and the spec list don't really do justice to the event that this car is in metal. the first thing you notice is the noise - it's *LOUD* - I got it home last night around 10:30pm and sheepishly drove through the quiet residential area where I live. Cue my wife hanging out the window: "Is that you? I thought it was HELICOPTER??"
The other thing is the otherworldly way this thing moves. I thought I'd driven some quick things before - AMG Mercs, plenty of quick BMWs and my previous RX-7s including the 323bhp one. This thing shifts. I'm alright with 3rd gear if I short shift and chicken out but I've barely dared to tease second gear! The suspension feels absolutely planted, the wing seems to generate real high-speed stability and the brakes are painful to push. I'm guessing about 400bhp and maybe a smidge under 1200kgs. The fastest thing I've ever driven.

That's not to say it's not without its faults - it needs a bit of love. The guy I bought it from lived in the wrong place for it - up a 1/2 mile broken, hilly farm track, I think he felt sorry to put the car through that. It needs a clean for starters! The exhaust is SO LOUD (did I mention that?) there's no radio - it would be pointless, it reverberates through the entire cabin filling your senses. The exhaust smells very strongly of petrol and driving around there's definitely a petrol smell emanating from the car. I'm thinking that it's either not mapped or mapped so rich that it's basically overfuelling everywhere - maybe the original owner added fuel pump and injectors and left it on the APEXi base map? Who knows? Seeing the injector duty on the APEXi commander go to the high 90s yet all evidence pointing to overfuelling I know I'm going to have to get it mapped properly for my own peace of mind (and to see what power it's pushing). There's a big hole in the console for a double din something. There's loads of rattly trim in the boot area (including part of an old race harness), the dampers are set to HARD. The LSD jerks the rear wheels on tight maneuvers. There's some wear on the (surprisingly comfortable, RZ only) carbon fibre Recaros. The clutch is rather sensitive (I nearly had kittens trying to coax the car into my tight garage at the top of a steep driveway - stalling it twice for good measure). There's an odd noise from the clutch area too when in neutral - it might be dragging or maybe the release bearing is fussy? The body kit needs a bit of attention with some sticky fixers around that shoudn't be there as well as rusty screws that need replacing with anodised ones. The rear undertray is missing (but could maybe do with a diffuser instead). The ARC wing - despite being super rare and desirable to a certain crowd is perhaps not quite to my taste. It's LOUD.

I also did a bit of detective work and found the listing for the car when the importer had it up for sale - the wheels were white (quite like them like that) and the wing was on some ugly risers:







So my plan is to get it mapped properly, investigate the funny noises, replace some light bulbs, install a stereo (for appearances), get a boost gauge, get an AFR gauge, convert the speedo to MPH ( guide), look at the seats and say "wow" a lot, do some drag, airfield and track days and build a replacement engine and have it on the shelf (just in case).

Thanks for reading!

A lovely example! Congratulations!
As to the above quote it really isn't that scary owning a rotary as long as you know what you're looking for and have good judgement as to whether the car has been well cared for. Plenty of enthusiast owned cars around these days that've been looked after extremely well.

Stunning - love an FD

Slightly disappointed with the content, only because the title promised so very much. I thought I was about to read about the rarest of things - an actual Mid Night owners car.



Still, all the very best with the car and yes, quite envious.

The car was modified in Japan by someone with some pretty serious intentions so until I'm proved otherwise I'm going to believe this car spent its previous life racing mountains and highways... smile

Looks great. 400hp single turbo must be pretty quick, where does it feel like it comes on boost? If it's running rich I'm sure it'll benefit a lot from a good remap.

Good decision to get back into an RX-7 after all this time, if you can wangle it smile


I had a chance to hang out with some of the local street racers when I was in Japan in '04, I'd be inclined to agree that with those mods it has most likely been in a few street races, whether touge, drag or shuto.

Oh absolutely, no doubts there chap! Definitely a Mountain screamer, or a route runner, and a great looker at that

I was just for a second, while the page loaded having a little moment hoping to read about an ex Mid Night car which isn't the 930 Turbo (blackbird) or the red fairlady 280Z!

I've been looking at that car in Rod Leach adverts since I was 13 or something.

Still the OPs car looks fecking awesome anyway! Congrats.

Few RC threads do much for me. I want this, and I don't typically drive that sort of car.

Enjoy it!

Wow! Thanks all for the great response - it seems that I'm not the only member of the 'Playstation Generation' to be hankering after Gran Turismo JDM royalty on Pistonheads!

Starting to think maybe I should have prefixed the title of the thread with 'Wannabe' to avoid some of the disappointment over genuine Mid Night Club-ness too :| sorry guys (you never know...)!

Anyway - here's my more thought through list of to-do items that hopefully I'll tick off over the coming weeks/months/years:

Convert speedo to MPH
Fix tachometer bouncy needle
Fix interior passenger door pull (gotta be the support behind the door card - had to do the same on my last Rex)
Get an FC commander mount
Replace sidelight bulb
Replace headlight bulb
Sort headlight angle
Patch Recaro drivers seat hole
Fit a double din stereo
Check and replace brakes as necessary
Pad garage walls with foam!
Investigate clutch drag (input shaft play?)
Source quieter midpipe or fit the spare 3" system?
Replace cigarette lighter
Vacuum the whole interior with seats out
Replace rusted screws on bodykit with anodised ones
Wash, polish, wax many times
Fit a boost gauge
Investigate Power FC settings (injectors, single turbo setting, boost control etc etc.)
Fit a Wideband O2 sensor and AFR gauge
Fit battery cut-off switch
Investigate coilovers and damper settings
Fix rattles from bootlid and boot area
Check boot and spare wheel area for rust
Get a proper map made and rolling road setup
Check brake pads and disks (and work out where they are from)

Anyone have more suggestions for my list?

Who's my best bet for mapping near Exeter? Do Dragon do rolling road mapping? Any other suggestions?

Yesterday I had the opportunity to give the RX-7 a more thorough test drive, 300 miles Exeter to Portsmouth and back. I filled up with £50 worth of Tesco 99 and expected the worst but by the time I got home I was back to where I started with about 1/4 tank left so the fuel economy really isn't that bad on a run. The trip literally was a shakedown though - on anything other than a smooth flat road there's a lot of crashing and banging and a fair bit of squeaking and rattling as the incredibly hard quantum coilovers refuse to yield. On a good road though those coilovers do something magical and the car feels total stuck to the floor.

Back in Exeter after 300 miles driving




The gearbox has probably seen better days though - although the gate is smooth and reassuringly positive it's sometimes a bit noisy in 4th gear and it definitely does not like shifting from 3rd to 5th without screaming at me. Also the clutch is my worst enemy still. I can either pull away at a snail's pace and keep it reasonably smooth but if I try to get it off the line at a medium kind of pace (as you would many times at roundabouts along the A303 on your way to Portsmouth) I'm kangarooing around and nearly stalling the thing. The previous owner said something about it being a 'Stage 5 competition clutch' which I looked up and found a description for: "Stage 5 - This clutch is for racing only. It is of a 3 puck ceramic design and offers optimum performance for the drag strip." So I'm just going to have to take it onto Santa Pod, rev to 5K and sidestep the clutch if i'm going to use it properly.

The brakes are scary good though, in its day the RX-7 had the best stopping distance of virtually any car on its stock brakes. This thing has been upgraded with huge Brembos at the front and they're amazing. I think the rears (which I'm yet to identify) will need new pads soon and I have no idea what the disks are or where to buy them (I've sent the previous owner a message to see if he has any info for me)

Before I took the car out all day yesterday I decided to investigate the boost settings. The last thing I want is for the car to boost too high on the available fuel, run lean and blow the engine. When I first took a test drive in the car before buying I noted that injector duty (measured on the A'PEXi power fc commander) hit 100% at high revs during a 3rd gear pull this is not good at all. The commander also measured .87 bar (12.6 psi) during that pull. I turned the boost down to about .65 bar (9.4psi) for yesterday's drive and saw 96% duty max across many pulls which is still not great but it was safer and the way the car pulled was still quite ferocious!


boost settings

However I'm not entirely sure I trust everything the A'PEXi is telling me about fuel injector duty since there's definitely been some work done on the fuel system - if anything most signs point to overfuelling:



That's the SARD fuel pressure regulator. I really need to know what injectors I'm running too but can't see them since they're under the upper inlet manifold. The A'PEXi thinks that the two primaries are 660cc and the secondaries are 850cc - this would only really be a tiny change from the stock 550cc primaries though and looking at the way the rest of the car is setup I doubt this bit would be ignored?



The other reason for wanting to pull the injectors is the strong smell of petrol when boosting. A few threads like this one suggest that boost is blowing the vapourised petrol and air past the rubber injector o-ring seals so I will look into that soon and really really have to get it mapped properly.

In other news, during six hours of driving the sound from the exhaust and screamer pipe pretty much dominates your senses, I think I might just keep it that way for the drama of it all. I'm also starting the appreciate the rear wing too:



It definitely helps me with judging the edges of the car when I reverse up the drive into the garage!

My mate Rich also sorted me out with a double-din head unit to fill the void in the centre console - not that i will be able to hear it!



Anyway - some more glamour shots from yesterday's road trip:


The tacho not working and the speedo lying - even in km/h!


Getting rained on in Salisbury (just what you need with a vented bonnet)




gaping hole in the console

And a few under bonnet shots too:


Big HKS turbo


A'PEXi boost controller


Knight Sports enlarged throttle body


HKS TwinPower ignition amplifier


Lots going on!

Also got lots of these stickers in a whole bunch of places - I have no idea who this company is or what they do and googling has given me nothing ?!

Looks good smile sounds like fun

Is it just me or are the wheels quite tucked in under the body despite the fact its got arch flares? you would think that you'd have those fitted if you were going to fit some crazy wide wheels that were going to stick out past the body.
Also I personally like the rear wing smile

Yep definitely looks underwheeled. The current tyres are only 245s on a 17. I might get some spacers and eventually go shopping for new wheels but not currently a priority since I want to make sure that everything under the hood is sorted before I do much to the appearance.

Incidentally though, having previously had an RX-7 on 265 18s I think the sweetspot for handling and ride quality is a 17" wheel on these.
