240Z RB20DET GEARBOX UPGRADE

[@CristianGarcia-zw2jz]

Currently going through a 5-speed swap on my ‘71 BMW 2002 and I definitely feel you on encountering all these obstacles. Congrats on finishing!

Love 2002’s! Very frustrating especially when things go wrong that are out of your control. Thanks and good luck

HEY LEGEND GOOD VIDEO! can you confirm its 18mm bore on the shaft to fit the L bell?

[@ando.engineering]

Thanks! I can't confirm myself as I didn't do the machine work or really discuss that with them too much. The best info i've found is here: zhome.com/ZCMnL/tech/240SX5spd/transmission.htm

Good info bro, loved your shifter fix, skills 👏👏 what they charge up in Auckland for the box work ? Mines still getting panel work done but got all this to come

[@ando.engineering]

thanks Mark, between $1500-2000. But that was including: - buying the rb20det box off them - Getting the box reconditioned - and the mods to fit the L series bell housing etc I ended up giving them my old box internals and stuff as well. Pretty good value I think. I'm not sure they would want to do it again for that cheap because I think it was a bit more work than they bargained for, but maybe they know how to do it now so it might be easier

Hi, Would you mind saying what clutch brand you used and if you still used the same flywheel from the previous swap video?

[@ando.engineering]

Hi, my local clutch shop actually put together a bit of a custom one for me, so I can't tell you a brand or model sorry. But it is exactly the same clutch and Kameari flywheel setup that I used for the old gearbox, and it still works perfectly.

@@ando.engineering Thank you!

[@ando.engineering]

Thanks! appreciate that

You must have the only functioning 240Z clock in the southern hemisphere! Have you verified the diff ratio? The reason I ask is that my ADM '73 auto was factory-fitted with a 3.90. I was under the impression that only the USDM cars had the 3.54 gears.

[@ando.engineering]

haha yeah the clock is funny, the ticking is so loud when the car isn't running. When I swapped the speedo drive from the Auto box to the manual box (in a previous video) it was the Black 17 tooth version, which from everything I can find online says 3.545 final drive, and my speedo seems to read accurate. I can't remember if I checked the diff gears when I had the cover off. But I remember turning the input flange and the outputs seems to correspond with 3.5 ish. Thats interesting though, my car is also an ADM '73 auto.

Hi, I'm doing a gear box swap like the one on your car but for a 280zx. Can you help me with a little question please?

[@ando.engineering]

Of course. Hopefully I can help

[@ebo69]

hi, nice video! what was the oem gearing ratio for first, and what is it now?

[@ando.engineering]

Not sure about OEM 240z, but the 5 speed that was previously in it had 3.32 first gear ratio, and I think this new box is exactly the same. However 2nd and 5th are now slightly longer - which I like.

[@Johann280]

Sick video as always !
