Mazda RX7 5.7 American V8
Discussion
Rather thought that was the case. Was beaten by one at a hill climb last weekend. His story was (as I understand it ) they made loads of them in the US so yes it was a standard production car and was OK to run in the standard production car class.
Most people were grumbling Sports Libra but as hillclimbing tends to be fairly friendly nobody actually protested.

Lies lies lies.The RX7 has only ever been supplied new from Mazda with a Rotary engine in all markets.
I suggest you shop him to the stewards.
I've an acquaintance from my Daihatsu days who had all sorts of issues proving that his Daihatsu Sirion X4 was a UK Supplied car and therefore eligible for the hillclimbe event he was taking part in.
Only once he had provided original sales brochures supplied from Daihatsu were they happy for him to continue.

Very sneeky! Most people were grumbling Sports Libra but as hillclimbing tends to be fairly friendly nobody actually protested.
As Marf says, only rotary engines in these from the factory.
Im guessing it was bloody quick on the hill climb then?
It was much the opposite!
The Rx stands for Rotary eXtreme. There was a concept vehicle that was produced by Corvette that had a rotary engine. It is a common conversion world wide, and it pains me to say it lends itself to the chassis and sounds amazing! But was never designed with the engine in mind.

I've seen pictures of the red Corvette rotary that was restored its superb in every respectThe Rx stands for Rotary eXtreme.

Would say fairly quick not bloody quick. It was well off the pace of a 2.7 1970s 911. It was dual driven and both drivers had run the previous day so had some practice. I split the two drivers times in the Griff without the benefit of Saturday practice and beat their Sat times. It would probably do well on a power hill but this one was tight, twisty and short so suited more nimble things. As Marf says, only rotary engines in these from the factory.

All depends what kind of V8 it uses - a basic 350 truck engine wont set the world alight, but an LS1 or LS6 (also 350 cubes) will fly.
Hmmmmm i think you would be better off with a 440 cubic inch LS7 with a sleaved block (lets you take it out to 440 Ci) some VERY nice cylinder heads, fast 102mm intake, a nice N/A cam and some decent headers! that would REALLY make it fly.chuntington101 said:

LS7s don't fit very well, you are better off with a LS2 or LS3 and for the money of an LS7 you'll make a 2 or 3 more powerful.
If that was the RX-7 that is doing a lot of the hillclimbs this year and did the speed trials then both the son and father who double-drive it really should know better.
What was the names of the competitors?
