Modified Stock Transmission Mount for RB25 5 speed
Jboogsthethug replied to Jboogsthethug's topic in Nissan RB Forum
ok interesting> I bought my motor/trans from a company here that pulled it out of a 240sx to swap in a 2jz, so they don't really know anything about it and they also don't have the contact info for the PO so I'm kind of stuck trying to figure it out ha. No kangaroo though, not that I've seen anyway. It is indeed toward the firewall, sorry the block of wood has a strap around it that is holding the trans in place as I build motor mounts. In the end, it fits and I do still have some room to push it even farther back if needed so that's the important part. Trying to identify the motor or trans has proven to be difficult though, as a lot of the tell-tale parts on the motor have been swapped for aftermarket parts and there doesn't seem to be much on the tranny. Haha I guess as long as the boot fits! thanks for the input, I'm probably going to scoot it back slightly more as I measured it and have about 2 inches between the firewall and engine, I'll put that back an inch and then have the shifter mounted slightly more centered in the hole.- 18 replies

ok so I thought I had the same transmission but I'm confused. Here are some pics of the fitment, I've got about an inch between the firewall and my engine, if that. And you can see my transmission shifter (not centered in the pic) is barely able to fit in the shifter hole without modification. Does this seem right to everyone else with their fitment?- 18 replies

I am 6' exactly and I've had the same problem. I am tryign to make it so I'll fit in the car and still be able to pass racing specs but I'm supposed to be able to have 2" between my helmet and a roll cage with a helmet on so I'm not sure how I'm supposed to make that happen. I worry about going too low because it becomes very hard to see what the duece I'm even doing when I'm so low ha. pain in the butt! I like the stock height too, but I know if I ever rolled it my head is hitting everything the roof hits ha. -

nice man! You're pushing past me in the timeline ha, looking forward to the pics! I'm interested to see what you came up with. Also, aren't;t you like over 6' tall? You look pretty tall in the photos you've posted, how did you get the seats to work out on the original mounts without hitting your head? -
good to know. All of this is really confusing to me ha. I mean, if I don;t have the windage tray perfect then will My engine blow up, do you know?

a couple really informative reads on building oil pans and the tech that goes into it http://garage.grumpysperformance.com/index.php?threads/building-a-custom-wet-sump-oil-pan.65/ https://www.chevelles.com/techref/ScreenInstall.pdf http://www.matrixgarage.com/content/how-diy-high-capacity-oil-pan-kit

Dang that's coming along nicely though! That looks like some quality repair work right there! Keep me updated on the oil pan for sure though, I am interested to see that in action.

Yes sir I agree, that thing is super slick. It seems like it holds him down pretty well, the footage of his acceleration is pretty mind-boggling ha. and no worries if not. I've got plenty to learn until I become a master builder, this will just be more practice ha- 18 replies

Hey man have you started on the interior flanges/baffles/whatever yet? I think I'm going to try and get started this week. I've been out for a few weeks after a dirt bike wreck so now I can finally start doing more physical stuff and I think I'm going to start here!

yeah I've heard the Mckinney mounts need a lot of shimming, dumb considering the price! do you have any pics of the welded setup? And I am drooling over the sequential, that thing is so sick. I've wanted one since coming across this 240z : one day I'll be cool like you guys- 18 replies

Modified Stock Transmission Mount for RB25 5 speed
Jboogsthethug replied to Jboogsthethug's topic in Nissan RB Forum
hmm interesting, I'm pretty sure I have the same transmission (I have been searching for days on identifiers and if there are even any other transmissions that the RB25 came with other than 1 model of 5 speed and one 6 speed model for the RB26?) and I can't get it through the hole without moving it pretty far back. I cut out the part of the trans tunnel mounts that hits the speedo sensor and I think I'm too far back. did you install yours into a 240z or a 280z? mine is a 240, if yours is a 280 it might make more sense as to why the hole isn't lining up with the shifter as well as it sounds like yours is. Great to see you chime in here ZT-R, I've followed your thread for a while now. If I remember correctly, you bought it with the RB26 already installed, right? If so, do you know if they bought mounts or built them? I'm worried about the leverage as well, I fear my placement is too far back. Do you have any pics of what you did? Also, how are you liking that sequential trans? that is a beautiful gearbox!- 18 replies

no problem, looking forward to it. also, that link seemed to be incorrect so I think this is the one you meant to post?
-
man this looks great to me! Would you mind taking a few pics of the inside to show what you did with the baffles or whatever they're called?
-
thanks for the in depth review of the pan, it's always good to hear people's opinions on a product, especially when it comes to these dang oil pans!
-
oh yeah I love the forums! and good idea, the more documentation online the better!

Did you have to cut the shifter opening to open it up more or did your shifter line up? I've realized I'll need to push m engine a bit farther forward but it also means I need to widen the hole so I'm hesitant to do that.- 18 replies

nice man!! It's coming together!!! -
no problem! Glad to help someone not blow up their engine ha. also, pat's email is: p.bowser@comcast.net

Jethoncho, great looking job! I'll be doing that soon enough. But be aware of the angle of the pan, it is supposed to be at a slight angle drooping toward the driver's side. If you don't correct for that it will be on the passenger side and you'd have to add an extension to your oil pickup tube to reach that far end from what I understand. Pat1 actually covered that i a thread I read recently. Beastioboi, as far as pat1, have you emailed him? He doesn;t get on the forum much anymore but his email is in his pan thread on one of the pages and he says to try that nowadays.

Modified Stock Transmission Mount for RB25 5 speed
Jboogsthethug replied to Jboogsthethug's topic in Nissan RB Forum
interesting, I'll have to keep that in mind. I got my RB from a 240sx so that's what mounts it has, not sure exactly how it will work. how far back did you push your engine? I've realized that with me pushing mine back it also has made it so I'll have to make my engine mounts where they angle forward from the engine to the stock mount location. I would imagine it would hold alright if given the correct support. Did you have any problems like that?- 18 replies

I recently picked up my RB25, and after looking at the crazy high prices for transmission/engine mounts and reading some of the reviews I figured it wouldn't hurt to give it a go myself. If it works out, great, if not then I'll buck up and pay the money for the pre-fabbed ones. Anyways, I decided to start with the transmission mount as it seemed easier and It would hold my engine in place beter for the motor mounts. First things first, I took the old transmission mount off of the 4 speed transmission, and it bolts up perfectly to the 5speed RB tranny. I was pleasantly surprised! That meant I could at least use the original mount to an extent. Then, I put the engine in place to get measurements. I pushed it almost as far back as I could towards the firewall. I noticed that the mckinney mounts seemed to bolt the engines straight down, but it seemed like you'd have to modify the trans tunnel in order to have the shifter go through. I wanted my shifter to be in more of a stock location, and it wouldn't pop through until I pushed it farther back. Then, I crawled under and got some measurements. These probably aren't;t universal and probably won't work for everyone, but what I got was this: The original mounting area allowed the transmission mount to be 14 inches long. The new area I was mounting was 10". The original mounting holes were 12.25 inches apart in the middle of the holes, with the other hole being directly center. It was also farther back in the tunnel by 5". I figured the easiest way to do this would be to make some sort of jig, so I put together a crude assembly with just some shelf wood and some nails. I measured the above measurements, cut the ends off of the tranny mount 2" in each side, allowing it to fit in the new location. Then, I took some 1"x 2" bar I had lying around and just eyeballed it basically, holding it above and marking it with a pencil, then cutting it along the lines and shaving it as needed. I then tacked it in place, got under and double checked it and everything fit really well. Probably nto perfect, but it seems like it is pretty much perfect. I then pulled it back out and welded it all together. My welds are supreme, I know. I also cut a corner out of the passenger side tranny mount thing that I need to go in and weld up. The Speedo sensor, as many already know, doesn't fit in that area without that being modified. Also, a little plug for grinding masks. I bought this a few years back after cutting my lip off with this very grinder. I wised up and decided I wanted protection across my whole face. Yesterday, there mustve been some sort of manufacturing error with the disc I was using and it exploded while in use. The biggest chunk hit me right in the face, but thanks to this bad boy I'm all good. I'm curious everyone's thoughts! do you think this will old, assuming my professional quality welds penetrated well? Of does it need to be more centered across?
