You would be wiser to trade in for a 6 speed than do a conversion. Even if you're doing it all yourself, with today's CAN systems and the associated wiring, it would be a headache. In fact i'm willing to bet that the 6 speed tranny itself would be one of the cheapest parts of the conversion.

The major parts:
-flywheel
-pressure plate
-parts associated with clutch R&R, pilot bearing, CSC (concentric slave cylinder), new disc, or one in good condition
-clutch hydraulic system, consists of plastic hoses with plastic fittings, not hard, cutout for master is already in firewall most likely
-PCM and wiring harness
-shift linkage-shouldn't be hard to get used

I'd say 3-4K without labor.


If you got the money and don't care either way, do it. But remember that with all the effort, money, and time it will take to do the conversion, you'll still have a slow Versa... I'm not trying to be mean, i'm just saying it like it is. If it's speed you're after, trade it in for a 6 speed model, and soup that engine up.

Yeah that'd be cheaper of course, but with every time the bellhousing is cracked open, the slave cylinder is recommended to be replaced (rightfully so, as if it goes while it's buttoned up, you have to take it all apart again, and probably buy a new clutch disc this time due to brake fluid contamination), and you'd probably want to get a new clutch disc anyways, cheap insurance relatively speaking, especially when you factor in all the downtime and if you can't do it yourself, labor expenses to take it all apart again.

Your call on whether the cost/benefit ratio is justified to you. If you have the MR18 you might as well put on Bob's lightweight flywheel while you're in there for that extra bit of pep. When i do my MR20 swap that's what i'm doing as well while it's apart.
