After searching the forum, I see that many people use a 51r battery when installing a Greddy FMIC. The instructions show the positive terminal of the battery closer to the engine. A 51r battery would put the pos terminal closer to the front of the car. The only difference between 51 and 51r is reversed terminals. Would a 51 battery fit better than a 51r?

 

Actually I think you have it backwards... the positive terminal is closer to the engine on the 51R, not vise-versa. Check out the pics below it may help explain things.

 

In the Greddy FMIC installation, the battery is turned sideways. If your battery is a 51r, the + terminal would be closer to the front of the car. Does anyone have a pic of a 51 or 51r with a Greddy FMIC?

 

Actually you would use the 51r. I used that battery for a while, but it was still too cramped in the engine bay, so I relocated it. The 51r will fit in there just fine though.

 

Here's pics of my 51r. I got the Blitz frontmount, but you get the idea of the size.

BTW Silverbullet, is that your bay? So clean...

 

Thanks. Yep... that's mine. BTW - I'll be adding either a FMIC or a Greddy Stock mount IC this winter.

 

Hey 93silverbullet, what kind of battery is that? it looks good.

 

Optima D51r

 

How many miles are on your car? That's almost unreal. Did you clean it or just don't drive it?

 

relocate!

 

72K on the car... but everything is mostly new now . Mainly it's my summer toy... rains alot here in the Northwest! I bought with just a little over 69K miles on the clock in April of 2003. I really wanted another Silver/Black combo. I looked for about 8 months to find the right car and then bought it. Spent all last winter doing the pretty much what you see in the pics and my sig. It's a hobby really and much cheaper than a girlfriend (or so I keep telling my wife )!!

But to answer your question I drive it and clean it (alot) .

 

relocate the battery?

i moved mine to the trunk, it seems to free up a lot of space, seems it would help cooling, espicially with a vented hood perhaps. itrs quite easy to do, dont be intimidated by the fabricating.
