CCA Requirements? Options

[Literati914]

I'll be picking up a flooded cell lead acid battery soon (budget oriented battery for a rear trunk relocation) and have been leaning towards a group 51R battery. I like this size because they are small - think Mazda Miata, small Honda Civics, Nissan GT-R, IIRC. However, I think the original group 34 had around 700 CCA [is that correct?] and the 51R tends to have a little less (425-/+). The first engine will be a 1.7, but then I'll probably upgrade fairly quickly, possibly before the typical battery dies.

I sort of recall the CCA demand being dependent on the needs of the starter.. or something like that. Anyone know for sure what our starters require, amp wise? And/Or Will the 425 CCA work?

I'm a HUGE believer in gear reduction drive starters.

Those always "hit harder" and require less "juice".

I'd not change a functional starter but if I had to replace one, I'd go GRD every time...

Not sure if (IMG:style_emoticons/default/agree.gif) with that as a good stock starter will do the job fine on a 914 ,then you have a 911 starter ,I have one and never fitted it because the 4 cyl one on my "six" is doing a great job .
Appears these reduction geared starters can be hit and miss dependent on where they come from and the quality of fitment for a 914 ,the supplier tells you it fits but if it's not right you may get a refund but can't see them replacing your flywheel cause the ring gear is all chewed up on your flywheel ,very much buyer "be aware " with these and IMO not an upgrade due to the possible issues .
Cheers.
