Thread: 16 p to 10 p engine swap

Yes, green top injectors are needed and they'll fit but the clearances must be done well also it's better to fit them with new copper washers and in the same order to avoid coding

I thought the cam profile of the 10p was unsuitable for green tops?

But if they do fit and will run ok - do you map for green tops or black tops?

I know nothing about the cam profile. When i bought my pre-facelift D2 15 years ago i knew nothing about Td5s, it ran Ok for a while but i found oil in the red plug so first time when the rocker cover was removed to change the injector loom i saw that it had 3 black and 2 green top injectors, i bought 2 blacks instead cos i like things to be perfect so that's why i assume that there's no problem to fit the greens to 10P engine even though the MSB ECU doesnt accept green top codes.

From memory... Whilst the later injectors fit, and can be adjusted to work in the earlier head, I believe a number of parts were upgraded in the cam drive system to run the higher pressure injectors.


If you don't upgrade the other bits I guess you could run the risk of breaking something.

You should never ever run 2 different types as Fery mentioned his had when he bought it.

Will this work? Does he need to fit the green 16p injectors and will they fit?

moving green injectors plus 16p injector rocker shaft plus 16p cam across to replacement 10p motor will work optimally with the NNN ecu already in vehicle.

the blacktops and greentops have different cams and injector rocker arms.

but to avoid playing with head bolts and splitting the cam carrier just leave the 10p intact and see how it runs in service before any panic or assumptions.

keep it simple.

An EU3 cam wont fit in a 10p head unfortunately.
The 16P NNN may have to be swapped for an MSB or to an earlier 15p NNN to get a suitable 10P base map. (<- I could be wrong on this, but with a manual 16P ecu it's defiantly a problem)

I'm a bit confused re the 15p vs 16p comment and the manual comment... What am I missing?

If he only changed the motor, the transmission, be it auto or manual should still be the same as before?

You may have other info on this particular job that I don't though!!

depends on whether the ECU was included in the swap? also is it an auto or a real mans car?

AFAIK a late model NNN cant be re-mapped to suit a 10p, and if he cant fit the 16p injectors and cam to his new 10p (thus turning it into a 16p, and it wont fit anyway, so moot) , he'll have to source an earlier nnn or msb to run the show. Not a big deal, unless its a manual - manual NNN's that can be mapped to suit a 10p are rocking horse poo rare.

He may be alright with a 16p ecu.... it could be the even later ones where the problem is (18p?) <- not sure when exactly LR stopped supporting the 10p mtr with replacement nnn ecu's

I've got one of these late EU3 ECU's which I bought to fit to a 10p MAN - the only way it'll work is if I fit a 15P or later head + injectors onto my 10P block and also convert the TPS and airbox to 15P onwards spec as there are no base map 10p files available to suite it.
This bloke wont have to worry about wiring changes, it's already there and whatever ecu he uses wont care about the extra, not needed wiring.
