I have installed a td27 turbo on the QD32 navara motor.
Have had some issues, even after the turbo was rebuilt. Need some advice on two things.
1) Turbo. Looking to buy a new turbo that was used on the Rd28 and some overseas Td27's. Anyone forsee issues with this? It's still a TB25 with the same A/R but is under half the price of the TB25 labelled as suiting the Terrano. Can't be bothered rebuilding it again, as obviously had a drama with the oil seal replacement when i did it myself.
2) Injector pumps. After adjusting load screw all was ok. When I adjusted Idle screw things have gone haywire. I have been told sometimes things can get stripped and block proper operation of idle. This needs fix/replacement as it is randomly revving up.
What i am looking for is a MECHANICAL pump with a compensator for the turbo. Did the Terrano 1 have a mechanical or electronic pump? I know Terrano 2's and QD32 turbos are an electronic pump.
3) If the Terrano 1 pump is electronic, is there any source for a compensator for these mechanical pumps, and if so, how much?
4) Is the standard Zexel 2S510 Naturally Aspirated 2.7 mechanical pump capable of flowing enough diesel for a turbo 3.2? Or will I need to get the 2S604 pump from the Naturally Aspirated 3.2? Does this even flow enough for a decent level of tune? Are the 2.7 and 3.2 pumps interchangeable as far as both fitment and timing?
Thanks in advance.
