2000 Mitsubishi Eclipse - Apollo

I have a 2000 Eclipse RS, yes thats RS not GS or GST just a good old 4 bang, I-4, 5 speed. As of right now its still completely stock but i will be building off the I-4 engine instead of getting a V6 or swapping engines. I have ideas i just need to save the money to do the things. Hate away
