Gearbox options with an SR20DE?


Recommended Posts

Good morning  - hope everyone had a good weekend and got some driving / wrenching in.

 

I am curious about gearbox options on the SR20DE engine I picked up, it came with a 71C 5 speed. Basically I am looking to see if a bolt-on 5 speed that is not quite as long is readily available. I am a total Datsun/Nissan newbie so thanks for the patience, and as a reminder this is going into a (cough, cough) non-Datsun.

 

I believe that a Z trans will bolt on but am not sure. I have to fabricate a driveshaft anyway so no newbie there...

 

Thanks!

'84-  300zx non turbo might work but it's not any shorter I think. I'll check but after '86 or so the 71C was dropped for a different one.FS5R30A? (I think, and will check)

 

If you want shorter get one (71C) from a 2wd D-21 Hardbody. Any KA engine should do but again, the early VG30 may as well but was changed later for an FS5R30A? same as the 300zx non turbo. They are around 30 " long.

 

Swap your SR front case on it. Not sure what the gearing ratios are.

Thanks Mike - doing more research here I am wondering if I can more simply deal with the shifter position by making something like this for the top linkage while keeping everything else (shifter kit from Summit Racing B&M Pro Ripper Shifters 45070 for TKO gearboxes but you get the idea)

Why not just use the transfer that came with it . It's stronger newer and parts are more available .

 

Good morning, it is longer than ideal and shifter mount is too far back BUT I think I can address the shifter via a fabricated shifter set up like above. I am hoping to use it...

I know what he wants, i meant you. 71c sits the same as the 720, so what advantage so you seek?

 

Edit: my mind instantly placed the 71c behind a ka, not an sr. Sorry, I'm slow.

Only downsides would be no speedometer pinion outlet, and the gearing may not be optimal.

I put a SR20DE bellhousing on a 71C from a KA24E powered truck for my wife's 1964 Datsun 1500 Fairlady project-- it worked out perfectly-- this is the only shot I have with it being mocked up in the trans tunnel.  It is 3" shorter (?) than the standard SR RWD trans.

Ha - yes, I have let the smoke out on occasion!

 

Got the engine fitted today - only had to the battery tray area by two inches (non-structural and I was going to relocate the battery back to the trunk anyway).

It looks like the existing, longer gearbox, may still work. I need to reattach it to the engine and take one more set of measurements.

 

Thanks again for the help and encouragement  -  I mentioned this forum to one of the guys at the workshop where I am doing this and he said "Oh, yeah, those guys are great". I agree.
