RX7 engine rebuild
Discussion
A friend of mine has an RX-7. The engine has so many small problems with it that I think we are looking at a full engine rebuild by now.
Does anyone have any good names of people who do this kind of stuff? I'm in the south-west of England, it would be quite useful to have it done somewhere relatively nearby.

i believe 'RotoTechnics' to also be very good...
the budget for a re-build being 2.5 to 3k

Close batty it's Rotechnicks www.rotechniks.co.uk
They are based just off the M4 at juntion 11. They did loads of work for me on my 5, they are very skilled and really do take their time to get things right for you.
Infact, they are so good I managed to persuade them to work on our MR2 too!
Ross Juniper who runs Dragon Performance did my rebuild and modifications and I would 100% recommend them. The build was done on budget, the workmanship was top drawer and the engine feels very strong.
My mate uses RE-Worx for all his work and is happy with their standards. He didn't have his rebuild done by them but I think his was done about 6 years ago before Re-Worx started up.
If you have a look at my profile you'll see the work I had done by Ross and if you want to get hold of him his details are:

Phone: 01404 891888
Address: Dragon Performance Ltd

The people to speak to about rebuilding wankels (from what I have heard/read) are RE:Worx
Based in Portsmouth.
Definately a good bunch but not The people. Certainly know their engines though as they built and run Eurpoe's quickest (1/4 mile) Jap car...
I'm off there this afternoon to dropthe rex off for a new clutch and mapping

How so expensive , it has very few moving parts so why 2-3 k ?
Cost will depend on the state of the 'dead' engine and how much is re-usable.
If it's just a refresh and housings, endplates and rotors are fine then it'll be cheaper. A new set of housings are ~£800.
Just gaskets, tips, springs and seals will be pretty cheap (~£200).
The rest would be labour, new hoses, etc.
How much would a rebuild of a piston engine that had failed properly (timing chain failure for example)? TurboT could let us know for a Supe engine...

One of my Tuscans threw a piston through the block which I guess constitutes a proper failure
and the first quote was £13K but after the dealer told them to take a reality pill it came down to £6.5K (and got even lower when TVR Power did the rebuild instead of the factory - but I didn't see that final cost as I was driving a Cerbera by then!) Bear in mind that parts for rotaries are not as common which usually means more expensive - I don't think £2.5 to £3K is too bad for a speacialist rebuild...

well put it this way, we can get a new Toyota shortblock for the Supra for £1800-2000, and then if you wanted uprated rods and pistons for approx 4k. The stock block will happily take 600 bhp though. Now if you want a 3.4 stroker and shimless bucket race head, you wouldnt see much change from £15k+, but these will take in excess of 1200 bhp ( proven) and have run 7 second 1/4's. Horses for courses
Edit, BTW, the 2JZ-GTE supra engine is non interference so the timing belts snapping is not and issue on stock compression, even upto HKS 272 cams. Toyota weren't daft
