I would go with brenspeeds b302 kit or JDMs 302e kit. Those are both great choices. Also, I would stay away from MMR. Have a few buddies that ran there engines and Heard a lot of horror stories with guys blowing there motors from them and having a lot of problems. Also if you go on s197 forum you can see that MMR isn't liked very much.
