When this Mercedes W123 rolled out of the factory it was powered by a 2.8 L M110 inline-six engine but recently this crafty owner decided to increase the cylinder count and displacement of the engine in his wagon by more than double. So the owner found a rare 7.3 L AMG M120 V12 and automatic transmission sourced from a Mercedes S73 W140. The engine produces 558 horsepower and over 720 Nm (531 lb-ft) of torque. These are the same engines Pagani used in several Zonda models. You can see the engine is taking up every inch the engine bay has.
The race car called Rudezon is finally running. The team from Linköping, Sweden took some time out to record the two-stroke Evinrude 300XP V8 running in the Volvo Amazon. The team still needs to install the transmission before it can move under its own power. I can’t wait to see it run down the drag strip.

This BMW 130i E87 was built by KJ Performance in Geiselhöring, Germany. They installed a 5.0 L V10 from a M5 E60 that produces around 550 horsepower and 520 Nm (384 lb-ft) of torque. The car also used the 7-speed SMGIII transmission from the M5 and a rear end from a M3 E92. The car now weighs 1,590 kg (3,505 lb) with a weight distribution of 55% front and 45% rear. Watch and listen as it races several cars at an airstrip.
This is Steve Groenink’s amazing 1973 Toyota Celica called Zongo. He started the project in 2010 and through a lot of hard work has created a very powerful and unique classic Toyota.
Power comes from a Toyota 1UZ-FE V8 sourced from a 1992 Celsior. These engines are very strong and take boost very well with little modification. Steve’s completely stock engine produced 573 horsepower to the wheels from a single Precision 6262 turbocharger running 12 psi of boost. The transmission choice started with a stock Crown A340e automatic transmission which was setup to run in full manual shift mode but very quickly gave way to a Toyota R154 five-speed transmission. Rounding out the drivetrain was a 8″ rear end sourced from a 1989 2WD truck which was narrowed five inches.
Fitting a V8 motor, a turbocharger, and all the required components and piping into a space that was built to hold at most a 2.2 L inline-four, is going to be a very tough task. There is going to be a lot of modifications and going through the build thread shows how much work was required. The firewall was cut and sunk three inches while the transmission tunnel was also cut and expanded. The steering box was swapped for a AW11 manual rack. The brake master cylinder had to be relocated and the engine intake was flipped to provide more room for the wastegate dump. This helped the transplanted engine work but with so much crammed into such a small area it restricted airflow which caused overheating issues.
To open the engine bay up for more room and thus better cooling Steve completely rebuild the entire front end. The subframe and suspension would be converted to a Mustang II front and would be supported by a custom tube chassis. While the engine was out for the front end modification, Steve decided to upgrade it for more boost. The 1UZ was upgraded with Ross 9.5:1 pistons, TTC chromoly I-beam rods, Crower 264/272 cams, and a second Precision 6262 turbocharger. With the twin-turbo setup the engine produces 650 horsepower to the wheels on 17 psi of boost.
Steve has done a great job detailing this project’s progress in the build thread. If you are a fan of reading good build threads then I suggest you view each page.
Mighty Car Mods is back with a brand new engine swap project. The guys start by buying a 1974 Volkswagen Beetle with a factory 1.6 L H4 engine. The goal of the project is to build the Beetle with 10x the power of the factory. Since the 1.6 L only produced 23.9 kW (32 hp) the new engine will need to produce 239 kW (320 hp). To achieve their goal the guys used a 2.5 L EJ25 from a Subaru Forester and rebuild it with forged internals and a custom Garrett GTX3067 turbo. Watch as the guys build their sleeper Bug in 48 glorious minutes and see if they achieve their goal.
