Lmao this is even a question? I'm tryin not to be biased lol but no matter what you do to your civic the e36 will feel better. Besides its always better to have the power stock than try to upgrade a sub par car to that power (especially Hondas which have that happen far too often)
Bottom line -- you have a better car now, why take a step backwards lol
E36s aren't that hard to work on, an there are loads of places for aftermarket parts or even deals we get on OEM that bring the prices down.
