1.3 transplant

[CMF_danarthurton]

i recently got an engine, gearbox and drive shafts from a 1.3 lx micra. what else do i need to make it work? does the engine come out form the top or bottom? is it eay from there?i have a 1L L micra atm. anyone got any tips?

Engine can come out from the top or the bottom.

I found it best from the top as you can use a hoist.

You will need all the gearbox to chassis mounts and all bolts.

Also you will need the gear shifter linkage unit/bars that join the shifter to the gearbox.

does the standard ecu from the 1 litre fit?i heard it does but not many ppl are too sure!

 

[CMF_micra_pete]

yes it does, and it will run the car, although the map is not the best.

I'll be keeping the 1.0 ecu when i do my transplant, for now, cos of the nats issue.

When you say the mapping will be bad, do you mean that the engine will just run under potential, or will i encounter lots of frustrating problems?

 

[CMF_kneival]

Been running fine on mine for the last 2 months but I cant get the bloody idle to sit at 750, its around the 1000 mark.

Be interesting to see if this happens with yours aswell or if its just a problem with my setup.

another question do the hubs from the 1litre fit on the 1.3 drive shafts?also is the shifter linkage and the mounts totally different to the 1 litre ones? wats is nats that everyone is goin on about wen talking about ecus? ta guys

 

[CMF_kneival]

The hubs will fit but the driveshafts are different.
The 1.3 CV joint has more splines and are thicker going to the gearbox, I think the hub side is the same but cant remember 100%, I used 1.3 hubs and driveshafts (complete)

The gearbox to chassis mounts are all different, the bolts on the rear (firewall) mount are different too.

Both the engine mounts are the same, the ones on the drivers side and front of the car.

The gear linkage bar is also beefier and bent differently, I used the whole unit from a 1.3.

NATS = Nissan Anti Theft System, its the immobiliser built into the ECU. Without the correct key you wont be able to start the car.

I've just had the transplant done and i'm running it with the 1.0 ecu and everything seems fine at the mo.

 

[CMF_spagatoni]

Oh yeah, i still have the 1.0 gearbox and it is well zippy! Top end is only about 10mph faster but i get there alot quicker!

Is it a post 1998 box?

If not let us know if you have any probs! The clutches are pretty weak on them.

 

[CMF_spagatoni]

yeah, the box is post 98. The clutch though, is a brand new standard 1.3. Don't know if its the light flywheel, but it now feels like i need a 6th gear!

My mechanical minded friends started talking about 'splitting the box'. The idea is to salvage a couple of the higher ratio gear cogs from a 1.3 box. The result (if possible) would be:

1st gear from 1.0
2nd from 1.0
3rd gear from 1.3
4th frm 1.3
5th frm something bigger or machined

or something like that!

is this possible?

 

[CMF_kneival]

Dont know but would be nice if it was.

Does the 1998 1.0 box use the same mounts and driveshafts as the 1.3 box?

 

[CMF_spagatoni]

I can only assume so cos all i supplied to the garage was the engine block. everything else is from the 1.0 and it all seems to be running well at the mo (fingers crossed).

 

[CMF_kneival]

Sounds good then.

After 1998 they changed the gearbox in the 1.0 to use 1.3 mounts and clutch. It should hold up well!

 

[CMF_spagatoni]

Thats great news then. Cheers!

Hope this help anyone else who's thinkin of doing the same with their post 98 micras.
