If you were able to change out the exhaust, intake and ECU reprogram, I would bet you can probably get 200 at the wheels with that motor. You know that Nissan doesn't have the boost all the way up. This ECU flashing tool would be the thing to get.

I can't see a Versa out there that is running anything bigger than the MR20 (in the US anyways). If the Versa platform is going to be a powerhouse it won't be anytime soon (again in the US); I could see it running a crazy turbo/supercharged set-up but as a track car.

This is all just my opinion though.

2010 Versa HB
~ DC Catback Exhaust
~ Takeda Short Ram Intake
~ 2J Racing Lightweight Pulley
~ DC front Strut Bar
~ Eibach's Pro-Kit Lowering Springs
~ APR carbon Front Splitter (yet to be installed)
~ 17'' Tenzo-R Concept 9 Bronze
~ 4 20mm 2J Racing spacers
~ EBC Ultimax Slotted Brakes
~ Hella Supertone

Sorry to bring up this topic a year later but I recently bought a new versa 2014 1.6 hr16de 5 speed one. I've always been interested in the sr motor and I know it would take a little fab work to get it to fit. Also I'm in Texas so my laws state so log as I have everything that comes with that sr it's legal

IMO SR20's are highly overrated... not that much potential, cost to power ratio is not great. With a bolt in MR20DE that puts out 140HP AND torque (roughly) STOCK, you can probably be pushing 160 with the usual light mods (free flowing exhaust, header, intake, all that), put the car on a diet and have a fun to drive quick/peppy car for a grand or two at most. Depending mostly on cost of motor (high mileage, low mileage, remanufactured/rebuilt).

The MR20 should have replaced the SR20 in terms of power modding but of course it never did, if there were stuff like cams, manifolds or ITB's it would have probably better power potential than any SR20. You can get aftermarket internal build kits for the MR20 though, with an option for 11:1 pistons if you want to stay NA, bore it over a bit if you want.

The SR can't be replaced for how overbuilt they are, they can handle obscene amounts of boost(not that I'd do it) and a lot of people seem to forget about the VET variant of it
As far as the SR is concerned it already has WAY more support than either of our current HR and MR engines so naturally it would be easier to find replacement parts for it. Yes 11:1 is great but at what cost? With the SR all there needs to be done is mounts and some added support so it doesn't rip apart with 250+ reliable ponies...

One more thing boring an engine lowers it's life especially pushing the ratio to 11:1 but the SR will keep on chugging pushing 8.8:1 before boost and making the same amount of power with NA, it's more reliable that way too

I'm not sure what motor is better but i do know that the support for the SR20 platform is ginormous, making it the better option for my swap.

If it is a SR20VE (VVL) then yes, or a DET. but not a DE.
You will not be able to use the Versa/Tiida ecu as it uses the CANbus system.
you will have to go with engin mangament system (that you anycase need to tune properly.)
you can put out well over 200hp on the wheels on Reef(High altitude) on a SR20VE that has been worked a little bit).

I ran against a Stock Sr20DE with my HR16DE.. and we sat next to each other, to my suprise.
