Finally found a real Twin Turbo 2GR-FE

[abechen]

Not an Evora but these guys may know how to build one for us. Too bad they are in Aus.

"The engine was built by Shane Wilson, owner of Shane Competition Engine Development in Mount Gambier, South Australia - He fitted Pankyl H-beam con rods, CP pistons and PSI valve springs, all made in the USA."

Buggy Specs

[Plackslayer]

Yep - the Jimco 2000


Specs available on another link that I (and others) have posted before.

I have emailed them requesting information on the build as it isn't exactly practical to send a motor internationally for work (especially one as common as the 2GR).

How about these guys:

St. Louis Performance Automotive, Automotive Repair, Audio Installation and Sales, and Auto Body and Paint.

They are in St Louis and built a 447hp Rav4.

Mark Jarvis is the guy to talk to:

Cant wait to see a turbo charged Evora. I would love to compare the turbo charged one to my car and see the power differences and horsepower gains over supercharger application. Now we just a brave owner to step forward.

Ramtin I think supercharging is the best for Lotus Cars. It would be interesting to see though.

Clearly a superscharger has better low rev's performance, but today a modern,turbo-solution is also without the dreaded turbo lag. Problem is that most aftermarket solutions are of poor quality, whereas the S/C solution is Lotus factory developed.

Biggest issue for a turbo in the Evora will be space, both for the turbos (you will need 2), the charge cooler and the piping.

If you ran an after-cat (really on this car after-collector) turbo setup, which have proven reliable and solid options on low to moderate boost (which I think is a given with this car) applications, you could get away with one turbo. Only issue will still be tubing. There isn't much room to play in the engine bay portion.

Superchargers are less efficient.

If there is room for two pre-cats, there is plenty of room for two turbos and their corresponding wastegates. Getting Cold air to 1 or a pair of air to air Intercoolers may be an issue so one may have to use water to air ICs.

Cooling seems to be the only stickler. Space isn't really the main issue - and if you need more - trunk delete.

The stock cat manifold is too restrictive and too long for driving a turbo, while the engine bay will not permit a turbo right at exhaust ports at least a longer but low restriction header system would need to be designed. The other issue is where to put the IC as it will be needed even more so that the SC setup, due to heat transfer from the exhaust. A single turbo will give much more turbo lag that you think, modern system have reduce lag but the physics will not allow its elimination.

We can get to at least 444 with the current SC and if you read the fine print on the GTE brochure you will see a call out of an IC. While it is hard to fit an IC it will be less work for us to do that than also fit two turbos

Ok for the aft side, what about to fwd cylinder bank? move the fire wall a foot fwd as in the GTE race cars? even then space is still tight just ask Alex Job racing.

Anyone seen the GTE's Engine with IC? Pictures?

Not seen any photos, so dont know where or how to moount. Just to be clear it is not the GTE race car w/ bored out 4.0 l NA Cosworth moded engine. It was eitehr the GTE road car or one of rge race cars specs above GTS and below GTE, check the Lotus motorsport sight, they have recently improved the info sheets on thh race car models.

Hate Turbos. Have a turbocharged 4 cylinder 2litre GM engine in my Opel Insignia. 250 HP and massive torque, but not fun, bit dull and everything but responsive. Needs more fuel for less fun than my Evora S. Superchargers are more responsive.

Comparing those two cars/engines is not really a good comparison - midsized turbo family car to a true sports car.

Try comparing the SC Elise to the Turbo Elise - then report back.

Anyone know the details on the engine setup for the road going GTE? I haven't been able to find any pictures or info on what they did different to get more power from the sc engine. Strange that there is so little info.

I love turbos. The hissing, wastegate, blow off valve. Nothing sounds as awesome. I had a DSM (Mitsubishi Eclipse). Modified the car to no end and that engine never gave out. With the right Turbo, you will not notice any lag even on the track.

The Evora is a much larger car than the Elise. 3.5 verse 1.8 is a big difference. A turbo with a built motor will put out serious power.
And if lightness is what you are after, go buy an Elise/Exige. The Evora is a pig next to them.

A pig that turns like a maniacal go-kart.

Although my Evora corners very well, it feels very big and heavy compared to my old Elise. The Evora floats over bumps while the Elise drives through them.

Nope, feel different about that. Evora is more planted, but still extremely agile. Just less rattle than my old Elise R. Gives more confidence so I believe most average drivers like myself will be quicker with the Evora.
