For the engine to run 3 parts of the NATS system is required, ECU NATS box and keychips. These parts must be from the same car as they are all coded to each other.
So no, the ECU doesnt need to match the original engine. As long as those 3 parts are there the engine will run.

This wouldnt really work because the ecu would have all the wrong data to run the bigger engine. It might well run, but wouldnt run very well. You would most likely be able to remap the ecu and use it to run a bigger engine (but the engine would have to use the same type of sensors and would have to be 4cyl as far as i know.
Oh not much done today....
First off we took the engine back out the Micra to fit the 2 missing flywheel bolts, fit the clutch, make more modification to the crossbrace so that it bolts in perfectly to the Micra chassis. So engine out onto floor.
Gearbox from the 2.0 was removed and so was the gearbox from the Micra engine as we needed the clips on the release bearing.
So Gearbox off, and flywheel goes to get fitted. Oops we are missing the spacer that goes on the flywheel. This coulda set us back weeks but fortunately I had one sitting in my drawer at home! So off home, grab the spacer and back the unit.
The main delay in having this put on was we were missing two of the bolts that were needed to bolt it to the crank. So it seems GA14 bolts are the same thread pitch but just a different head on the bolt. SR = 12 point whereas GA = 6 point.
Flywheel being fitted
Then onto the clutch fitting. Once again we were lacking the correct bolts. So an order to G spec in the US got us a brand new set of clutch bolts. Delivery took a week or so.
Thank you to Phil on AOC for donating the clutch.
Clutch taken from an SR16VE.
Clutch fitted :
Gearbox then re-fitted :
After this we then fitted the engine loom to the engine. We had to re-wire the injectors due to it being a phase 2 loom and a phase 1 engine where the injector plugs are different. So wired cut and replaced with the correct plugs then heat shrinked. Then NATS box was plugged. And the Micra keychip swapped for the right one.
Key chip fitted :
Engine then wheeled back into engine bay and lifted into position :
Mounts bolted in :
Once that was done, the engine loom was fed through the firewall into the cabin. All plugs and fuseboxes were plugged in and a battery was fitted in place.
The engine was then filled up with oil. 3.5 litres. No oil in the gearbox yet due to no driveshafts.

SHE LIVES. First turn of the key aswell…Easy.
Unfortunately, as expected the wiring wasn’t totally correct for the fuel pump. For the fuel pump to prime before starting the headlights must be switched on. So some re-wiring needed there.
But the main thing is, its mounted on 3 mounts and it runs fine.
YAS.
Also a big thanks to Willie/Nistro for coming all the way from Aberdeen today to help us out.
Next job...Front crossmember...

good security feature!

(no news about the parcel Scott
Hope it turns up Seb
And I certainly hope so too :L and yeh pistons, rods and crank are all still there
personally i didnt find much of a difrence between the ga16 and sr20 in a k11, on paper the sr20 looks the stronger engine but like in the case with putting a c20xe into a corsa,often always more than not the 1.6 gsi will out gun it on a standing quarter, it all comes down to weight proportion and torque, the ga16de only produces a few nm's less torque than an sr20, coupled with the fact the sr20 is a heavier engine the power difrences almost equalise, but then theres alot of other factors to reconsider, sure its fun and i understand the circumstances of this build allow for the use of an sr20, but just dont be dissapointed when the lad with the ga16 takes the win:grinning:
agree with you open handedly on that one marty boy, its just simple physics, although a higher speed is achieved with higher capacity engines, id more often than not pick a ga16de over an sr20de, sure the tuning scope is reduced in terms of generic after market parts but i think theres one thing we've all learned being modified micra owners, and theres one phrase that geniously and incomparitively sets us apart from the rest " BUILT, NOT BOUGHT FTW"(Y)(Y)(Y)
no debating here scotty boy, just plain agreements
about that gearbox mount, its gunna have to be preety strong, as the passenger side driveshaft is shorter, alot of torque is converted through that side of the box/mounting point....dont want you looking daft at crail:grinning:
Your patter about the ga16 being as quick as an sr20... Erm. Nah!
My old almera was ga16 with cams, header, intake and catback. I swapped it out for an sr20 and the difference was massive. Including a full 1.5 seconds off the quarter mile time.
Then i bought my autech, the extra 30hp was significantly noticable.
Ga may be a lighter engine in theory, but in practice by the time you take gearbox into account there isnt much in it.
Truth is im a very strong believer in the ga16's potential, but sr20 will always be the superior engine in performance, tunability and power application.

we'll agree to disagree, ive seen the difference first hand, perhaps you just had a crap ga16, i cant imagine a worked ga16 being slower than a standard sr20
i guess the only thing left for me to do now is build yet another ga16 micra and see you at crail (Y)
Yeah go for it. But the sr20 will take the win...
Crap ga? Yeah... 25 thousand granny miles on it. Serviced every 9 months at nissan. Mint condition. Yeah real crap. Anymore straws you wanna clutch?
Also your comment on torque figures needs more research. Standand torque in a ga is 100ft.lbs. An sr20 is closer to 130 stock. But soon as you let it breath that lurches over the 150 mark.
CG will win at crail
Stani is this gonna be another close race like the civic and almera? Lol
