If you want to get the most exciting acceleration experience on the surface, in addition to spending money to buy the three great cars, you can actually build a more cost-effective hybrid sports car with a more "higher" cost-effectiveness. For example, the top-level V8 of Mercedes-Benz SLS AMG or the 13B rotor of Mazda RX-7 were transplanted to the Lotus Exige weighing less than 800kg... (Pictures are from the Internet)

We know that the first generation of Exige was powered by Rover's engine technology, and the 1.8L engine from Toyota was replaced on the replacement model. Although Lotustor adjusted the supercharger to increase power, it is indeed difficult to create a pleasant and terrifying pushback feeling with the high rotation of the small-displacement four-cylinder engine, although its curb weight is less than 800kg.

Therefore, power improvement has long become the first issue in the foreign Exige modification circle, and a variety of schools have gradually emerged in the selection of engines. Among them, the relatively mature modification solution is nothing more than transplanting Honda's K series engine. But the owner of the car Craig did not choose the modification method that went with the flow. After a series of feasibility analysis, it finally stuffed a Mazda rotor heart into the Exige's engine compartment and renamed it "Rotus".

The pocket-sized 13B dual-rotor engine and the Lutes Exige, known for its lightweight, are a perfect match. It can be seen that it only takes up half of the space in the cabin. Behind the engine is a Precision Turbo PT8891 Gen2 CEA turbocharger with a diameter of up to 88mm, which provides a stable 2.06bar boost pressure.

MicroTech LT-10 computer takes over the engine management work. After multiple enhancements, the 13B rotor engine can finally burst out with a maximum power of 542kW (737 horsepower). The transmission is matched with the Hewland serial transmission. Of course, the high rotation characteristics of the rotor engine are based on the squandering fuel, so it is imperative to replace the WeberSports fuel pump and Denso injector.

If you want to add icing on the cake to the acceleration performance of "Rotus", you have to make a big deal about lightweight-Craig chose a composite fiber window and widebody kit, and the hollow design it uses also exchanges for the dual benefits of heat dissipation and downforce. In the end, "Rotus"'s weight was controlled at 743kg, and he successfully stole 37kg lightly.

forged rims are also for weight loss services, with front and rear data of 17x9J and 18x10J respectively. In terms of tires, the sizes of 235/40 R17 RA1s and 295/30 R18 R888Rs are respectively matched with Toyo tires with sizes of 235/40 R17 RA1s and 295/30 R18 R888Rs. The posture is controlled by BC twisted teeth, while the brake system is replaced with a package product from AP Racing.

This "Rotus" is also quite highlighted in detail modification. The exposed racing fuel filling port creates a more extreme fighting atmosphere. In addition, the windows are also racing-style design, and the circular openings can effectively allow the hot air in the cockpit to be discharged quickly.

"whimsical" rotor transplantation has greatly increased the performance of this Exige. The thrust-weight ratio brought by 542kW (737 horsepower) and 743kg car weight is enough to make people afraid. What is this concept? You should know that Koenigsegg Agera RSR is not that powerful...

Lutus Exige modification case - transplanting 13B rotor

If the life of the rotor engine is worrying, then you might as well turn your attention back to the V8 engine that has both sentiment and performance. I believe you must still remember the Toyota Hilarx with AMG engine transplanted. This time, the modification master Quentin Boylan repeated the same trick and stuffed another 6.2L M159 V8 from Mercedes-Benz SLS AMG into the body of the Lotus Exige. So, how did he successfully put the elephant in the refrigerator?

This AMG-Lutus is transformed based on the second generation of Exige, which means that the Quentin Boylan must do its best to put the plump M159 into the compact body with a wheelbase of 2299mm. You should know that the longitudinal length of the M159 gearbox accounts for almost 1/3 of the entire vehicle, so the original cabin structure is incompetent no matter what.

Quentin Boylan had to cut off the rear of the car and hand-made a racing-like steel pipe braided frame to accommodate the engine and gearbox.Ultimately, the new frame structure increased the chassis length by 150mm, while the rear axle part was widened by 100mm.

The 6.2L V8 engine from SLS AMG is equipped with a dry oil pan commonly found in racing cars, and adopts a large cylinder bore, short stroke cylinder design, and a double overhead camshaft air distribution structure, so it has a very charming high-turning feature. In the original state, it can provide maximum torque of 650Nm, but Quentin Boylan was not satisfied with this. He then customized a more efficient intake and exhaust system and replaced it with a KN style and MoTeC computer. In the end, the maximum torque of this engine increased by nearly 20%.

Exige's original slender drive shaft obviously cannot withstand such a irritating torque output. Quentin Boylan uses local materials and is perfectly replaced by the original drive shaft of the diesel version of BMW 7 Series. In terms of suspension, the Dutch brand AST 5300 professional track version series is selected to provide professional racing-grade support and response speed.

rims come from the British local brand Forgeline Motorsport, and the forging process it uses further reduces the unsprung quality. The brake system has been upgraded to AP Racing Pro 5000R six-piston calipers, and the brake performance is unquestionable. The redesigned shell part of

can undoubtedly enjoy the gift of air more accurately, including a customized front shovel, rear diffuser, and a large rear wing pulled off from the Ferrari F430 GT3, which can further increase the air flow rate at the bottom of the car to obtain more extreme air downforce. It is worth mentioning that although the body kit looks like it is made of fiberglass, it is actually hidden under the yellow coating, which is made of real carbon fiber.

interior atmosphere is refreshing, and it is hard to imagine that the originally simple cockpit will be filled with racing elements and artistic atmosphere. Under the lightweight modification benchmark, the instrument panel and seats for replacement are customized from super strong and ultra-light composite materials, and the special pattern style also effectively relieves its tense fighting nerves. It can be seen that the shift lever of the traditional serial transmission has been completely removed, and all its shift instructions are taken over by the carbon fiber shift paddles behind the "OPM". The AMG logo on the right side of the steering wheel will remind you all the time in the track to be cautious!

Editor's comment: Although the Exige model has not been introduced to the country, this does not prevent us from capturing the additional charm of these two modification cases in the dual dimensions of technology and aesthetics. The Lotus Exige is known for its lightweight and pure control characteristics. Such accurate drag and strengthening is undoubtedly a respect and recognition of the Lotus car manufacturing concept.
