Is it possible to fit an ls1 or ls3 erod Chevy engine in an evora? Those engines are almost as reliable as a Toyota, with a heck of a lot more punch. Moreover they are on the small size for a v-8? I know it's been done in several 996 p-cars with good results.

Likely not, and if you can:
Heat management would be a critical problem.
Finding a compact transverse transmission rated for the HP would be a problem.

re: LSx into a Lotus

There was a thread here about someone trying an LS3 into an Exige.

GM put a V8 into front-wheel drive Impala, so there was a transverse box for it. Also GM F40 manual transverse box (used in Saab's and G6) is good for 400NM or 300ft.lbs. i.e. it can be used with a very mild LS motor.

Transverse V8 would fit. The question is why? Transverse gearboxes are the limiting factor to power. Look at MB CLA 45 AMG, 350ft.lbs. torque curve flat 2000 to 6000 RPM, tuned DOWN so the Getrag DCT hoilds up i.e. this is the tranny's rating.

Therefore, Elige and Evora is limited to 300ft.lbs. before you get into some really $$$ and interesting hardware.

Supercharged and turbocharged Honda swaps yield good power, fit and are inexpensive. There are Audi/VW swaps

I thinbk a Subaru swap would be interesting. It is a longtitudinal transaxle. It can hold the power. 400hp is easy and 500 is not hard to get. It should fit into an Elige very well.....

Porsche transaxles will hold up to LSx V8's when properly modifed and there is an aftermarket.

Swapping an LS7 + T56 into a BMW or a Datsun 240 is easy. It is smaller, lighter, more powerful and more reliable than the original.

Swapping an LXx into Evora or Elise would require a transaxle and extending the wheel-base i.e. Hennesy Venom. That is all it is.

Elise has about 22" from firewall to axle centerline.

LSx is about 26" from pulleys to bell-housing. Need 8 to 10" from bell-housing to axle shafts, depending on transaxle. Therefore, need 12 to 14" extra wheel-base on an Elise... may almost fit into an Evora....

Good LS7 is $6k + headers + cam = $10k for 600hp+
Transaxle + adapter + clutch is at least $12k. Porshe transaxle flipped upside-down is the cheapest option.... Otherwise, the price rapidly climbs past $20k. For example Ford GT drive-train would fit, also.. $40k!

At this point, you might as well buy a kit (car) from Fran at SLR!!! or Factory Five GTM!

Hell if that 's the issue, why not put an Evora body on a Porsche!! Best off both worlds. No more ugly Porsche body with some off the best frivetrains in the business . Think of an Evora body strapped to a GT2!!!!!!!!!!!!!!!!!!!!!!!! Now that would be called Viagra for the 4+hr hard on it would give!!!

If you've already disposed of your sanity anyway and have too much money to spend you could also put in the 3.2 Ltr V6 together with the dual clutch gearbox from the Audi TT.

There are tuning kits for that engine going to 600 hp / 720 nM torque.

I believe with enough money it would be possible. I am sure a lot of custom fabrication would have to be done. Essentially the Venom did this.

I bet for the price of an LS1/3 and cost of fabrication, you could build up a Lotus 3.5 to a 4.0 with the goodies out on the market.

Or you could buy a 500hp engine built already from Swindon Engines, who makes race-ready version of the 3.5 Toyota 2GR Lotus supercharged engine swindon-engines.com
