Hey guys, I have my sisters R33 GTS-T here and the damn battery is always flat in the morning. I thought it might be a buggered battery so I installed the one from my Z and that ended up going flat in just one night too.

I jumped the car and tested the voltage across the terminals and it was only 13V and when revving the car it actually droppe to 12.8V. OK, dead alt. Ill get another one but it doesnt explain why its making a freshly charged battery dead over night :P

I checked how much current its pulling when the car is off and its 170mA. Would that be enough to drain a bettery over night?

could possibly be the light in the boot staying on

...which means that you put your sister in the boot & shut it !!!

Then when you've kissed and made-up...

it can often be the security system draining the power away.

Sounds like a process of elimination = NEXT PLS? :P

Measure the current draw through each fuse. That will at least narrow it down a bit.

I think ill do that ey. I tested the current draw at the battery and it said 170mA but I could have had it on the wrong settings and it was 1.7A lol :)

      Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild.

      If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.

      Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.

      Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
