td27 in a navara.

mobyone · Jan 17, 2010

hey guys. been a while as i have been away for several months.
anyway, i decided to swap out my td25 from my navara as it was gubbed. i bought a terrano td27 and fitted it. well, what a pita that was. swapped out the sump, oil pickup and the metal bracket for the bottom of g/box bell housing. just to get it to mate properly, i also swapped the flywheel and clutch as i didn't want any i/p shaft type related issues and the terrano clutch had, had it anyway.
so, now engine is in, several of the sensors are different, and the fuel pump does not have nats on it.
also the alternator was an oil cooled number, so i swapped that with my original one and blanked the holes in the oil galleries.
i don't have a td27 service manual, but as these engines were in d21's, anyone out there got one i can download for free as i am a cheap ass at heart?
also, there is a sensor in the inlet manifold which was not on my td25 lump. what is it please?
i went to swap out the throttle position sensor from the non nats fuel pump as they had the wrong connectors, only to find what i can only guess is a stop solenoid and another wire going around the back of the fuel pump, what is this please? and what is the best way around the fact that the pumps have different connectors?
lots more questions that i will have i am sure, but if anyone can help with these ones first, at least i can get the thing running.

This is interesting. I have Just bought a Terrano engine with the box. The seller said the ECU need changing as well on the Nav. Is this the case? or with a manual pump i can use the same Navara d22 ECU to power the Terrano Engine?

taps05 , the nav ECU stays in place with the mechanical pump conversion , you just need to snip the diode that lights up the EML light , its a 10 min job , which terrano engine did you get ?

its a 2001 2.7TD Terrano engine with a mechanical pump. Just to be sure, how do i distinguish between electric pump and mechanical? There is only one electric cable coming from this pump i have and 2 people have confirmed its the manual pump. This Engine was supplied without the mountings which are different from the YD25 engine. Im hoping to get hold of the terrano mountings this coming monday.

One other thing. are the gearboxes similar? should i leave the Navara gearbox on? or i should bring Terrano engine with its gearbox? How about the transfer box?

its an electronic pump on that model year pal , if you look , it wont have a throttle cable , or , if it has the intercooler on top , you must use the terrano box as the navara box wont mate upto the terra engine without an adapter which are quite expensive , the speedo drive needs to be swapped from the nav box too
