Here's what I use on the 32 and 33 gtr. Supercharge MF40B20L Goldplus series is a good choice if you want to keep the standard size. I have to use a 40 in the 32 as I have too much shit around that area to run anything bigger. In my 33 it's a 55. The MF40B20L is 390cca and compact, this is the standard physical size for 32 and 33 GTR. The Century MF40 version by comparison is 330cca. MF55B24L is a better choice as they are 490cca, but they are wider. These seem to be my picks as they best available under $200.

After that you go all out with the Optima AGM Yellow tops. By far the best, but approaching $400. They are available at 700cca plus and people have reports of batteries lasting 7 years or more. I don't see the point as Supercharge Gold plus is 40 months no questions asked replacement warranty.

The MF40 is the standard factory size and MF55 is actually the Nissan cold weather pack upgrade size, hence why you can fit both. Same depth and height, just a 55 is wider as mentioned above. So if you can run at least a 55.

More importantly than any battery though is get a Ctek, especially if it is not a daily driven car, which is most GTRs. Need a good maintain charger.

@GTSBoyIs that true - as in outright replacement, or is it just the pro-rata

Complete replacement, as in within 40 months of purchase if it fails, full new battery on Gold Plus series. My old man even did one literally at about 39 months from purchase recently on the XR6. I can say I have done it about 3 times across all of my car's ever. The dealer stamps it on purchase, and they are very adamant about retaining and supplying your original receipt upon replacement, but apart from that, yeah no problemo. Sometimes they'll want it overnight to prove it, but if it is stuffed its stuffed and they'll see that.

Cool, you realise that it is the right positive terminal instead of the left, which is standard in a GTR ? It does have the correct small terminals though.

CCA is also 450 on a 38ah battery.

Does not sound like good value unless it does last you at least 5 -  6 years, as that is the price of 2 x MF55B24 with 490cca and 50ah. I am yet to justify the price of Optima. Happened to have this in the ute for reference:

There is absolutely no question they are good, all the serious 4WD and off roader guys run them here. I just couldn't justify $300+ for 38ah and 450cca.

Post back in 5 years and see if it's still going strong ?

You really don't get what I'm saying do you ? 38ah is the smallest, most piss weak size battery for any car, regardless if it is a $100 or $1000 battery. As I said above 50 minimum is generally the go for any car now, and paying that much for such a small battery just seems silly. Anyway sounds like you went and got one so hope it lasts ok.

When people have been going through the trouble of going to an Optima yellow top they go for the big ones and make them fit for a massive increase in CCA and AH, or to mount them laying down as they are AGM.

650 CCA.

This is essentially the physically largest and largest capacity battery you can drop into the stock location.

Hey if this is in your 32 , next time you need a battery the Supercharge Goldplus equivalent is the MF80D26. Same dimensions but 80AH and 720cca ?

Just an update, took your advice bk and went the supercharge gold plus? Starts awesome and very reasonable price. Went the 55B24.

Hey Ben,

Awesome insight into the topic.

Quick question, what would be involved with swapping over to Optima Yellow?

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      I don't think the shuffle can damage the turbos. It only happens at low shaft speeds and loads. It's just annoying (to some people - others are tickled by the effect) and it quite possibly reduces spool performance a little bit.

      Oh dear. The panel beating needs to be done before the filler work. Do you have a photo of the dent before you started? Hard enough to not flex and only hit the high spots?  What do you mean it was just temporary?

      I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly.
