Have you signed up to FDUK yet? there are regularly cars being broken and parts being sold over there, it may well be that something nice pops up on there and the prices are usually much more reasonable than the standard Ebay floggers!
I am on FDUK and the Rotary Club sites, keeping an eye out 
Engine is stock, need to find out if anything has been done to the fuel system etc.
I plan on getting a Greddy Ti Exhaust to start with and then start looking into mods to keep it more reliable, such as Rad, fuel pump and remapping.
Over the winter I will be looking into decats and all the supporting mods to ensure it dosnt go bang

Id look at getting an accurate way of monitoring temps in the car asap too, the stock temp gauge is so useless i don't even have words. If your looking at doing breathing mods decat etc anyway it may be worth you just getting a PFC ecu + commander in the car straight off. This is probably the most commonly used ecu for tuning and the hand held unit will give you much more accurate temp info (air/water) as well as boost pressure and injection rates.
I think the guy selling the car has a FC commander avaliable so will see if he will include it in the sale.
I have been reading up on base maps and guides. Never needed to map the supra I had so its all new to me, seems very interesting.
Am I right in thinking most mods are safe on the base map but it needs tuning when the cat comes out?
Also what happens when the cat goes back for mot's? Can you save different maps or do you have to tweak the fuel settings?
Sorry for the amount if questions

most reliability mods are ok on the base map, but like you say any major changes to the breathing or performance will require a tune.
With regards to Mots it is possible to either have different maps on the PFC or to simply lean the fueling out for the duration of the M.O.T.
It will be well worth taking it to a rotary specialist come M.O.T time anyway, the cars are marginal on emissions at the best of times so you may find a bit more leeway with people familiar with the engine and it peculiarities, especially once you start running more horsepower.
I've not had mine long enough to have to try and get it through an M.O.T yet though as it came with a full year, so some of the other owners will probably have additional advice and frankly as i premix the fuel on mine i suspect it will be a real pain to get M.O.Ted next year!

You can tweak the map to get through emissions easy enough. You're best going and speaking to a decent local RX7 specialist. If it's an import and 95 (I think) and older it should go through the non-cat test anyway I think.
As for mapping you're probably ok doing one of the standard mods on the PFC base map as it's a little rich. You really are better getting it mapped properly though. You're looking at around £350 for a full remap from scratch, after that the tweaks will obviously only cost labour. But it will make a big difference.

my head nearly always wins.
wanted a weekend and track caterfield, ended up with a weekend and track BMW 330ci
only time when the heart wins is when the head agrees.
Nissan 200sx and Lexus LS430 - both were heart wants, and both won on the head front. Never regretted either both were superb, but eventually age, running costs, impracticality and potential issues caused the head to overrule the heart and they had to go, but it took 10 years and 5 years respectively.
You follow your heart the rex is one of the best looking cars ever made in my opinion.

Went to see the RX7 on Wednesday (our 3rd year wedding anniversary of all days...wife's idea!)
Body work was in good order, bonnet is getting resprayed due to decals causing the paint to fade. Everything checks out paper work wise and currently just discussing the extras.
It will come with a +99 front and wing as well as an Apexi ECU which will be mapped along with the engine rebuild
First plans will be suspension, breaks and bushes and then cooling mods and replacement hoses for the rats nest etc.
Just waiting to hear for an eta on the engine rebuild.

Hey guys,
My heart is saying RX7 FD3, good power, potential classic and being a turbo can tune it fairly easily if I wanted.
Down side, large bork factor, high fuel costs.
Another (biased) RX7 owner here. You are correct on fuel costs (20-22mpg) but I've had excellent reliability in the last 7 years (~25K miles). One window switch died but that's it. Two kids (age 11/7) can squeeze in the back with 5'6" adult in the front.My heart is saying RX7 FD3, good power, potential classic and being a turbo can tune it fairly easily if I wanted.

Noise, well mine is stock and you can't hear the exhaust. Intake/engine noise is quiet, more like a jet turbine that a piston engine. The excitement comes from how fast it moves.
To minimise bork, the 99' front helps (2x cooling area).

Got a 99 spec front going on as part of the build, will be updating all the cooling over winter Noise, well mine is stock and you can't hear the exhaust. Intake/engine noise is quiet, more like a jet turbine that a piston engine. The excitement comes from how fast it moves.

20-22mpg is pretty good! I keep hearing people say they are running in the mid teens. My tuscan would get around 25 on a good run but would often be around the 18-19mpg.
Although i appreciate that mine will be worse with a street port and remap etc I would suggest that 22 mpg will probably be the outlier rather than the norm for your consumption.. especially if you like pressing on regularly.. sequential turbos do some scary things to your fuel gauge once both are on song.
Personally I'm now practically on first name basis with the staff at my local shell garage as i seem to be in there daily

I might keep a record just for the lolsCurrently undergoing the same dilemia.
Spend £5k getting my RX7 a new engine (my fault) and a few trick goodies or put that money down as a deposit on a new GT86...
Rx7 Heart
GT86 Head
I'm getting home and booking that car in for a new engine.
