They are the same, with different names...The MacStar is the newer version, with a 2 piece head and head button, where as the Hyper Engine will come with a one piece head/head button...The Nova Rossi P5 head and head buttons are direct drop in's if you want to switch a Hyper into a Turbo head button...

I've heard the OS carb will fit it, but IMO it isn't required.

I like the stock carb...The trick is having it setup correctly from the start. Read the "Hyper .21 8 port Carb." thread, and it'll teach you how to best setup the carb, so it'll tune just like it's supposed to...

I have ran a Nova Rossi carb on one, and it's a direct drop in. The engine ran great with it...

Hope this helps...

Have Fun...Burn Nitro...

I've ran many...Most lasted me right at 5 gallons of abuse. I ran the snot out of them to see what they could take. I recommend replacing the front bearing out with a Picco or similar, and it'll run great. I'd bet I would have gotten more life out of them if I was a bit nicer to them.

I really like the 2027 pipe with a double bend manifold on it. Out of all the pipes I tested on it, it performed the best(IMO)...

Have Fun...Burn Nitro...
