1978 Datsun 280Z RB25 Restomod
Jboogsthethug replied to Jethoncho's topic in S30 Series - 240z, 260z, 280z
Man I'm happy to finally see some pics of someone actually going through this process, thanks for the great documentation! It all looks great! Are you going to swap the fins on the shallow pan to be the opposite direction? Or did you already do that? -
It doesn't even look like you flipped it, awesome job! I'm impressed for sure! Also, where did you get that huge aluminum chunk?

Post up pics when you get it! I'd love to see what it looks like! I restored mine and I'm pretty happy with the results but I'm not even sure I'll use it moving forward ha, we'll see! man I am so jealous! I can't wait to start going through my suspension pieces! T3 makes some superb stuff, share some pics of yours when you get a chance! -
Hey All, I'm hoping to pick up a stock RB25 driveshaft, anybody out there with one lying around? Message me, thanks.

Modified Stock Transmission Mount for RB25 5 speed
Jboogsthethug replied to Jboogsthethug's topic in Nissan RB Forum
Interesting! I figured out a big part of my problem was just leveling out the engine/tranny. After I got it more level it goes farther back thankfully! I believe I have the RB25DET, I need to pull out the pics or the tranny but from memory that matches up with the pics. Very helpful info! -
Leveling Out an RB25 Engine Before Fabbing Mounts

Also, I talked to @stony about his old RB swap via FB and he shared this with me : "I have to see a picture of the pan again but I believe the bigger part of the sump needs to be level and then the shallow part of the pan has a tilt to it. I've actually seen people mount the RB straight up and down with no issues I believe they put a drain in the back of the head though" I thought that was interesting and good info. Also, @winstonusmc, I measured the pan based off what stony said and it was 11 degrees, you were pretty spot on! -

If anyone is reading this later, I also verified the angled engine question in this thread: You can see that two of the users in that thread posted pictures of their under engines that verify the angle towards the driver's side. Thanks again everybody! -
That sucks, I agree with LanceVance, not a total loss yet but that still is lame

I can imagine the digital gauges that have popped up in recent years must be a lot better/easier to use than the old tools! Thanks for the tip, i'll look into getting one -

Here are a couple really good articles covering driveline alignment and pinion offset, for anyone who sees this in the future: http://www.rustynutscarclub.com/driveline.htm Note: This article mostly applies to build out the rear end but has some good info as well for aligning driveshafts. https://www.dragzine.com/tech-stories/pinion-offset-guide-and-how-to-with-chassis-engineering/ Even more on pinion angles: http://www.wolferacecraft.com/pinionangle.aspx https://www.hotrod.com/articles/91758/ https://www.quickperformance.com/Pinion-Angle-Measurement_ep_45.html https://www.hotrodhotline.com/setting-pinion-angle http://www.superchevy.com/how-to/transmission/1502-how-to-use-tremec-driveline-angle-finder-app/ -
Leveling Out an RB25 Engine Before Fabbing Mounts

Good points, I'll make sure and get that correct first. Meaning that the engine pinion or whatever is angled to point directly at the rear diff, and vice versa? ok perfect, just ot make sure I am understanding, your RB oil pan isn;t level at the flange, but the driver side is lower than the passenger side? and 2.5 degrees meaning your transmission is lower than the engine, correct? Thanks for the help, I appreciate it! -
This looks awesome! I am jealous at how fast your car is coming to fruition! Also, digging how you threw the bash bar on behind the G Nose, spiffy!

Hey all, quick question that I'm having trouble finding the answer to. I'm about to fab up the engine mounts for my RB25 and I've read online somewhere sometime ago that I needed to level out the engine using the flat flange on the bottom for the oil pan. That makes sense to me, but when I try to twist the engine to be flat it pushed my transmission shifter into the passenger's side of the trans tunnel. is it better to go off of the transmission shifter and get the exactly flat or to go off of the bottom of the oil flange? Also, I know that the oil pan has a bit of an angle on it, around 3 inches deeper on one side. Is this to flatten out the bottom and the engine actually should be angled a bit? I'm hoping somebody may be able to walk out and snap a few quick photos of their setup and describe it a bit. Thanks in advance!
