51R is a battery size. They are a lot cheaper. I've got Interstate brand w a good CCA rating for Chicago winters.

 

Well, I finally got the damn box in there.. with the help of a friend. Actually, he did most of the work.. I just supervised.. I had to take the small pipe to a machine shop to get it cut about 1 1/2" in all.. peice of ****.. To all that plan on getting a M2 intake box.. don't buy the hard pipes from the RX7store.. that don't quite fit.. and I forgot about checking the offical M2 website for the real M2 hard pipes.. And about the box.. I forgot to bolt the damn box down.. so, that's why it messed up the hood.. and in the process of putting the box in.. I broke the small radiator hose.. it had too much pressure from the intake box.. And my friend put my C's short shifter in last night, while I was at work.. it's pretty nice. Kinda stiff.. but, I like it like that..

 

MY GOD MAN!! What the hell is that?!?!

 

Big turbo and K&N for a SMIC?!

 

I see nothing wrong with that setup.

 

Other than the ducting and intercooler sprayer are not finished.





It's a Magnus GT42 and what's left of the M2 medium intercooler from the first picture.

 

Oh yea, I didn't say there's was anything wrong with the setup, but Justin said, "MY GOD MAN!! What the hell is that?!?!"..so, I told him what it was..
