Question about 2001 Mitsubishi Eclipse
Hi. OK, at this mileage, I would recommend to upgrade after you have done the following to the existing motor:
1 Recondition the head assembly. The entire head Assembly.
2.Inspect the crank shaft for rod bearing damage. Machine the shaft if needed.
3. Inspect the transmission for possible valve body issues and other normal ware at this mileage.
4. Preform a block compression test. this will expose any cylinder issues that may be present, at this time.
5. Flush the engine coolant and oil sections, thoroughly. this will remove build up form the engine. Highly recommended.
6. Totally rebuild the entire throttle body and manually scrub the intake free of carbon build up.
7. Flush the transmission, thoroughly.
All the check points above are needed in order to accommodate a full upgrade at this current mileage interval. Your stock transmission should be able to handle any possible upgrade you may consider, unless you are considering going to a higher output cam and CPU setup. In that case, I would adjust the transmission setup, as needed. It all depends on what horse power you are targeting. It will be more economical to just recondition your existing engine before upgrading if there are no leaks present, at this time. I would recommend to look into the available enhanced cpu chip kits for this vehicle. The chips increase horse power, efficiently. High performance catalytic converters are available along with the exhaust upgrades.

Any motor or transmission can fail at any time. If you choose to do the internal upgrades yourself and this is your first time I would just do it to this engine. This way you will gain the experience for the next one if you choose to do it again.. Also if you mess up and destry this engine you may have a reason why so next time you wont make the same mistake.
Any time you add more power to a transmission you will stress it more. The number one part that fails in stock cars is transmissions so as far as what your trying to accomplish is going to be based on the size of your pocket and whether or not you can afford mistakes.
Personally other than a cold air intake system and an exhaust I would not do anything else on a mitsubishi. They arnt made to be a strong race car.
