I have a 1995 240sx transmission in my 280z and am in the process of rebuilding it. I need to replace the front bearing on the counter shaft. It is a 62 x 22 x 17mm bearing. It is a Nachi bearing which is the original bearing for the trans. I would like to replace it with a new Nachi bearing but I just can't go to a Nachi bearing distributor and order it. It is a proprietory bearing made just for Nissan and must be purchased thru them. I called Courtesy Nissan and they want to know the VIN num. on the car which I don't have because I only purchased the trans. Does anyone know the part number for the front bearing on the countershaft for this 5 speed. The number on the bea…

So I'm slowly building up a nice cylinder head with some good bits from Japan (Kameari Titanium retainers & 8000rpm safe valve springs) but when wondering about picking out a cam I got to thinking about the bottom end's rev limit. Mine is an 81 F54 which I had cleaned up (hot tank, hone, check for straightness, etc) a year ago and to which I fitted new bearings and rings. Having only the seen addition of a deeper and baffled sump & a higher flowing oil pump it is basically stock. I know the L28 revs less than the L24 but does anyone have a specific number I should keep in mind? For example if the bottom end can only handle say a max of 6500rpm it doesn't make much…

I just pulled apart this r180 that I got from a 74.5 260z and I’d like to confirm the gear ratio. I pulled the cover off and I don’t see any stamp on the ring… even spun it 360* 🥲 This thing looks nasty. Really want to clean out the casing. Gonna flip it over and let all the crap come out.

Guys, when i bought the car i took a risk. I knew it was overheated and also later found the head cracked. So far we have replaced the head and car seems to run decent. Took these compression readings last week and wanted to share. Cylinder 1: 130 Cylinder 2: 130 Cylinder 3: 135 Cylinder 4: 140 Cylinder 5: 130 Cylinder 6: 130 I have yet to see if it burns any oil. Not driven too much. But i expect older engine to burn a bit which is fine. I change every year and dont drive too much. What do you guys think about these numbers? Personally i expected a bit worse but I think 130+ should be acceptable? Any advises for on-going maintenance are appr…

Guys, I am debating between 20W-40 and 20W-50. The weather in CA does get in the 90s in Summer but in colder winter it does come down in the 40-50 range. Right now I am at 20W-40. Let me know what you guys use. Also any good brand in the 20W-40 range with good dose of ZDDP?

I'm in the process of rebuilding a one, maybe two, or three, not sure, FC5W71B transmissions. It's just about the LAST thing I have yet to do on (to?) a Datsun. Always thought it was too hard and needed too many special tools. It's not. I want to record details of what I found and did along the process, but not in the usual way. -I will NOT take a video of the whole process. There are plenty great ones on YouTube. I WILL record the URL's of any helpful video's I find to help centralize the source for those videos and maybe critique each one's strengths. -I will NOT add the 300 photos I will take along the way. I WILL take photos and add notes on the…

Clutch cylinder is leaking as in image. Its brand new. any ideas what could be cause. I am 99% sure its installed properly? I am fine with buying another and putting it on if it will fix the issue? It starts leaking and pouring out when i pump the clutch. cant even keep enough fluid in line to attempt to bleed line. btw. i have been absent a couple months. I have my car somewhat running finally. i will post later in mechanical on current engine issues. thanks to everyone who has been super helpful.
