Mazda MX-5 with a LFX V6 – Part 1

1991 Mazda MX-5 with a LFX V6

Konstantinos Sidiras from One Lap Heroes is upgrading his 1991 Mazda MX-5 with an engine swap. The first video explains he was originally going to use a LSx V8 but decided to use a 3.6 L LFX V6 from a 2012 Camaro. The V6 makes 323 hp (241 kW) at 6800 rpm and 278 lb-ft (377 N⋅m) of torque at 4800 rpm. The team is installing the V6 using the LFX swap kit from V8 Roadsters along with an upgraded drivetrain and support components.

      Meh. It’s about 80 pounds lighter than an LS7 but down 182 hp and 197 lb ft. To me the power gains are worth weight penalty. Of course the biggest penalty would be in the price. That’s where the real decision comes. IMO.

    Ponies vs Revs. The LS Family make the power but run out of revs. when your car barely weighs 2000 lbs the extra 1000 rpm in every gear from the V6 make the car more enjoyable. Remember you save quite another few lbs with lighter flywheel,clutch,gearbox etc…

    Quite simply, usable power per dollar, the LFX wins hands down. On the other hand, when it comes to sound, the LSX wins hands down.
