Okay, I think I'm pretty much set up for my next project on my car. I'm ordering my KLZE, I'm getting an ACT clutch, but I also want to add headers when I do all this. I'm thinking of going with MSDS. Does anyone have these? They're suppose to be exactly like the HotShot's. What do all of you guys have on your cars? Can anyone give me a little advice? Oh and I was told that when I replaced the engine, I'd probably have to replace my motor mounts. Do I just replace them with stock units or are there any others that anyone's used. I've seen the MazdaSpeed one's but there something like $560. Is there any cheaper or should I just get these. Thanks.
