Enjoying watching the build. Thanks for documenting. Gives all of us some ideas.
Which engine did this car come with stock?
The Spyder GS comes from the factory with a 4G64 2.4L SOHC engine. It's a 7 bolt block that comes from the same 'Sirius' line of Mitsubishi engines. Unlike the N/T coupes, it's fairly easy to swap the Spyder to the 4G63t platform. There's a lot of write-ups of people combining the 4G64 bottom end with a 4G63t head for some serious power too.
Yep, same motor and trans mounts, same exhaust from the catalytic converter on back, even the same transmission housing. The only difference in the trans are the gear ratios. Makes the swap that much easier as I can use the 4G64 flywheel (which is lighter than the 4G63t as well) and bolt the 4G63 right up to the existing manual trans that's already in the car.I did not actually realize the 4G64 was positioned the same way in the Spyder. Interesting.
