In my opinion go with the sr20. Its lightweight and powerful, perfect for the type of driving your after. Easy to install. Parts oem and aftermarket are a dime a dozen. If you can get past the fact its only a 4 banger and there will be some extra room in the engine bay you should be quite happy with it. Ive had many sr20 powered cars (6 actually) both turbo and non and I love them.
