There is an article in this months Sport Compact
Car about how some dummie spent big bucks shoehorning a
300 ci LS1 V8 into a third gen RX7. No expense spared.
Surprise! The 159 ci rotary was .12 G quicker on the skid
pad (that's a lot) and 3.85 seconds quicker (that's a lot)
around a real tight road course. (Streets of Willow) The 80
to zero stopping distance was 35 feet shorter from 80 MPH. Duh!

What a way to ruin a great car.

But here is a chance for some one to track this goombah down and possibly
pick up a good rotary either cheap or free.

Yep.

BTW the magazine got the weight of the 3rd gen turbo 13B engine
at 425 pounds. Pure unadulterated BS. Bare weight is under 200 pounds.
Add 50 pounds at the outside for the dual turbo's and another 30
pounds for the flywheel and clutch.

Hi Paul,
more to the point,
I thought an LS1 was a 350 ci engine, ie in Oz it is 5.7 litre

Yes you are probably right. I was guessing. There are several
version of basically the same engine. LS x I can't keep they straight.

BTW they are in no way related to the famous "small block". They are
an entirely different die cast aluminum block engine. Chevy is trying
to capitalize on the racing fame of the original small block. The real small block
is a much more robust and stiffer all cast iron block engine. The
flexi block LS1 feels like a hand grenade getting ready to blow
at full chat (350 HP) and 6500 RPM. It is scary. Never the less
the real small block was worth 2 hours at racing HP levels
(700 to 800 HP) and then it was a mass of cracks.
