jesus i think 900CCA is a little extreme! and at 27.5kg its a tad heavy.

This is in my 32, but a 550CCA battery does the job fine. I would really say you would need anything more powerful than that.

No matter how big of battery u get make sure you alternator is big enought to charge it o/wise you'll burn it out and kill your new battery anyway

Anyone know quickly off the top of their heads the load rating of an r33 alternator?

I got one of these .......

http://allpurposebatteries.com.au/shop/pro...eafdb6795305e70

Its small and I needed the space

Its light - 8KG

Its powerful - 380 CCA - Starts the 2.6 without trouble and my alarm doesnt send it flat.

Its reasonably priced.

All R33 GTST Coupes have them in the boot. R33 GTST S1 Sedan's are Boot, but R33 S2 Sedan's are under the bonnet I believe

All r33s are in the boot....Time for me to get a new battery as well!

Very good point!

I would also like to know the load rating for an r34 alternator?? I want to get the biggest battery the car can handle without the alternator burning out.

270cca will start the car just fine!!! The battery weighs a lot less and costs a lot less too, cheap enough to replace from bigw if it does go bad. Also fits the spot with standard bracket too.

After I installed a $3500 stereo system and wanting to be able to play it for hours without charging the car led to the following experience with batteries...

I've been down the route of trying first 950cca 850 standard ca then yellow top then red top sealed 550cca and beack to a cheap 270cca.

It cost a fortune (almost $2000 for this experience) and in the end if you are having trouble starting it is probably corroding factory wiring.

The real reason batteries are in the boot is to keep the temperature down...They will all die in the end if its heat in the engine bay causing it (the temp under the bonnet with the turbo can easily cook batteries). I have a R33 sedan series2 with the battery in the front and I even installed vents on the bonnet to keep the battery cool (it worked or I'd have moved it to the boot already).

If you really want to spend big $$$$ get a lithium-ion version (special effort on your part) which will last longer - put it in the boot to keep the heat down to preserve battery life and it will last 10 years and be light weight.

If you are looking for performance do not forget lighter is better! Power to weight ratio is important, and save yourself a lot of money on batteries, just buy a nice light weight cheapie (try to keep it cool to preserve its life) and replace it with a new one if it breaks.

I hope this saves fellow skyline enthusiasts some money.

Another tip - batteries sulfate if they are allowed to go flat, so make sure it gets charges no less than once a fortnight. If you let a red top go flat 2 times it will only have 6 months of life left in it.

      Mistakes were made, my R34 Story

      In a few years from now, you'll regret that. It'll eat away at you, knowing the truth of the ugly hiding beneath the beautiful exterior... 😛

      I don't think the G2 profile is particularly dangerous for the engine per se, more just are you actually ok with the turbo lag trade-offs? If the answer is yes then go for it. I personally don't think I'd be ok with it because I spend so much time at lower RPMs and I really enjoy the feeling of being able to stay in 5th gear on the highway and just roll into the throttle to get boost. Or staying in 3rd gear on "gentle canyon cruises" without feeling the turbo lag too badly. The 525 pump should be able to run flat out on factory lines but I would bet the pressure drop from pump to regulator is quite impressive. I don't know how much it would be exactly but I've seen figures like 30 psi thrown around.

      It's interesting seeing everyone talk about what level of risk they are happy to tolerate.  Building a GTR always has a level of risk, you could be that lucky guy that drops 20k on the engine build alone and still has the thing go pop on the dyno. Life is fun like that.  The way I see it, the thing is a toy to be enjoyed. I'd be happy to turn up the power on stock motor and limit the risk with sensible tuning and engine protection. If it still goes pop, it is what it is. The car isn't a daily driver so it can happily sit while a plan is made to sort it out.  Given this thing will be a street car only, I really feel it's worth the (relatively small if managed well) risk to turn the power up to around 350KW on e85.  I don't think anyone getting into the skyline game now is doing it out of logic. Surely it is a purely emotional decision so I'm not sure how important it is to think about the engine build logically. The heart wants what it wants.  @joshuaho96 little note for Josh, I run my 525 pump flat out all the time and through the factory lines without any issues. (excluding the melting connectors, that's sorted now. we'll pretend it never happened lol)

      But the Nexus S3 is very expensive and won't be as purpose-built for the application as a separate electronic boost controller :^) More seriously my pet issue here would be that the Walbro 525 running at 100% duty cycle is going to require more FPR than the stock setup can handle. I'm also pretty sure from what I've seen elsewhere you might want to slow down the pump regardless unless you're going to come up with some way of upsizing the fuel lines coming from the fuel tank. Factory 8mm fuel line doesn't actually flow very much if you want to keep pressure drop down between the fuel pump outlet and FPR. If you really want to "keep it simple" I would run only as much pump as you need and source a fuel pump controller to slow down the pump in the vain hope of being able to run stock-style FPRs which are pretty dinky. Or just use the HICAS lines and it should be mostly fine. OP should also really think hard about what profile they'd want out of the turbo. My pet choice here would be the G1 profile rather than anything higher power but YMMV. I already think ~stock turbo lag is pretty bad so I don't want to make it worse. In "gentle canyon cruising" I found that I spent a lot of time around 4-4.5k RPM. I also recommend DIYing labor if you're detail-oriented enough. Costs are high for labor + if you do it yourself you can be your own quality control.

      GTSBoy is again on the money. My actual advice? Sell the car. (really). For what it's worth as is, you can sidegrade into something much better. If you care about function then this is the actual move. If you want a Skyline to perform, set aside about $100K to do it. This is NOT a typo. You will see right away these are two very different mindsets. Realistically we're talking full restomod for any Skyline still kicking around. Have an honest think about which one you are.. and what you want to do, and how much you want to invest in this (with no return).
