Makes a good read!
I was in a similar postion to you, needed a new car, LOVE the looks of the RX7, heard they have great handling etc... and generally reliable if they are looked after (which is what I wanted after having a RWD Saff Cos).
I also decided Id prefer to spend some quite big money and go for one already making good power with a good spec.
So I arranged to view a friends of a friends 440bhp dyno'd RX7, street ported, rebuilt with receipts etc... On a T77 I think it was...and never been so disappointed! Thought it was slow, noisy (screamer pipe), too laggy and it seemed to idle really funny. The guy who owned it was a enthauist (he had a rotary tatoo!) and told me they all idle funny when they have the seconday 1400cc (or whatever they were) injectors.
He also told me the rear diffs and boxes are weak on RX7 and after breaking 4 diffs on my RWD Saff I decided there and then RX7s werent for me!
Looking at buying a standard Evo 7 now.
