Hey all, i'm a new fc owner. After selling my s13 hatch i decided no more pistons after ruining 2 engines. So i went out and got a '87 rx7 na deep blue project car. It's been sitting in this guys front yard for years and i drive past it every day to work, so one day i stopped by and next thing i know i'm googling rx7 forums. I love the car and hope to make it more quick, more sly, and more aggressive. It is na and i'd love to swap in a 13bt but i cant decide between s4 and s5, is the few extra horsepower worth the headache(if any) for the s5? Anyways, glad to be an owner and now a member.

Thanks,
xic
