RX-7 rotary probs

Anyone got any experience with rotary engines?I part-own an RX-7 Turbo II which has lost a lot of performance. We knew itfelt down on power, but we timed a flat-out 20-60mph whilst driving it theother day and it took 8 seconds! It used to do 0-60 in 6-7, I guess we'd belucky to get that up in 10 seconds now!Other symptoms.. runs 'lumpy' from 3rd gear onwards.. stick your foot downand it is anything but smooth. Also, it's stopped doing the 'cold start'cycle - it used to rev up to 3000rpm if started from cold, now it just sitsat standard idle and can be very difficult to keep running until it's warmedup (which isn't much fun, considering it could flood with the usual re-startproblems).Obvious answer - engine on it's way out... apex seals gone. But, could it bethe turbo? The gauge shows we're getting full boost OK but it doesn't soundthe same as it used to. Any other ideas? I'd love it if it was justsomething simple but I really don't know enough about these engines.Cheers,Chris.

Nope :)

My RX7 owning friend uses some specialist near Manchester for his stuff.

There's an RX7 forum on the web somewhere that he uses - go find it :)
