Fixed link so it works:

I wonder if he changed to a turbo type of rear suspension with the upper link and splined half-shafts or if he kept the fixed length rear shafts.

BRUTE POWER OF the M119 engine

I think this engine would do the job.

The Mercedes-Benz M119 was a V8 engine produced from 1989 through 1999. It was available in 4.2 L; 5.0 L; and 6.0 L displacements. It was a double overhead cam design with 4 valves per cylinder and variable valve timing on the intake side.

One can have the core w/117K miles on it for 900-1500 bucks!
WOW, DOHC 32V and VVT!

Add 2 turbos GT2871R, and yo can get 900HP

Here is the picture of M119 in da C11 race car Mercedes-Benz C11 - Wikipedia, the free encyclopedia
Looks better on Sauber Mercedes C11, huh?
Noticed the Bosch CIS injection on the N/A engine?

I can understand doing a swap to a v8 to be different, or because it sounds good. But to do the swap for HP I don't see the argument especially with modern 4 cylinder turbo technology these days. A v8 is probably going to be heavier and ruin the best part of Lotus ownership...handling.

I'm doing my swap to an LS3 for that reason, but also for easier servicability/reliability.

Mine works out less than the standard 918 V8, but I've revised the suspension as it was a four-pot car previously.

Yea the GM LS engine is an obvious (and great) choice. Great power/torque, even better power density (they are surprisingly small and fairly light), great reliability, fantastic aftermarket support, and inexpensive.

The real question is the transaxle.

Hmm, wish we had those over here, I suppose it's just a shipping carton away. Isn't that what they used in that S1 with the Audi v8 swap several years ago?

Yes, if you are referring to Andy Hills' conversion:

4.2 V8 ABZ conversion of Lotus Esprit :: motorgeek.com

There are many variants of these boxes about, such as he used, and also recent revised versions like which sits in the Boxter/Cayman S models. You have to be careful with ratios though, it took me some digging around to get information to confirm which was best for the engine I'm using.

I know some support exists on your side of the pond from a few specialists like Advanced Automotion. I haven't dealt with them myself, only know of them from discussions on the GT40s forums, where people discuss these topics in detail as their replicas rely on the few transaxles available that fit mid engine rear drive cars.

Never knew that was an option. Very cool!

Do you have anymore information on it? The specific trans? The adapter kit used for LS?

You can look at any F2WD family version, for example, like 01E, 01X, 0A2. These units have an integrated bell housing. You have to have the adaptor-plate custom made for the engine you intend to use. I had mine done locally, but apart from the previous suggestion linked in my previous post, the options in the USA I'm not completely familiar with, except what i've heard from GT40 enthusiasts, such as:

Kennedy Engineered Products

Or there is a guy in Dallas, TX called Eric Martin who makes a kit:

GT40s.com - View Single Post - LS1 to Audi 01E Adapter COMPLETE!

He made a set for a guy in Norway that is doing a project with an LS4 mated to one of these Audi/Getrag units:

Might also try these chaps who mod LS engines into Porsches:

Renegade Hybrids

Has anyone tried to fit Porsche 915 box into Esprit?

This looks interesting:

I was told 915 can handle (only) up-to 300 HP engines and if I want to be "double-sure" I should look at 950 box, which is capable up to 500.

One of the coolest I ever saw was a ground up restoration of a mid 70's VW Thing, they slapped a Porsche 930 Turbo engine in it (300+ HP) 2,000 lbs. Must have been a bitch if ever floored it keeping the front end on the ground!

I bought a '85 910 turbo engine a few years ago from a fellow in PA. Drove up to pickup the engine, and besides the esprit, there was also a formula atlantic setting in his garage.

He had picked up a Nascar Grand National v6 from a busch/nationwide series car when they changed over to v8's, and the v6 was going in his '85 esprit.

I actually bought my '89 Esprit a few weeks ago just so that I could do an engine swap! I intend to use the new Ford Coyote 5.0 V8 DOHC engine.

Way more reliable and much easier to maintain than a any Lotus engine. What is ironic for the purists to know, is that when Lotus was winning F1 championships and was the first rear engine car to win the Indy 500, the engine was the original Ford Quad Cam Coyote engine. latter F1 championships were won with the Ford Cosworth engine. Besides no cam belts to worry about, the engine is actually lighter than the Lotus V8.

Bellhousing are readily available becuase guys have been using the Renault Transaxle with Ford V8's for years. Tornado Sports Cars, UK sells the bellhousing for either a Ford or Chevy engine. Another cool feature you can see in the photos below is that the intake manifold is reversable.

Lotus/Ford has a long history of success, so why not apply the same principles to an Esprit?
