Need to chane engine

[Dieseldude]

Hi to all,

I need to change the engine of my 1st gen KIA Sportage, I have a many probz with the RF engine.

My choices are Nissan LD20 or Toyota 2C

1.Any feedbacks on the engine above?

2. What other reliable and affordable engine (2.0 L disp) you guys can recommend.

Actually I already transferred the engine of my owner type jeepy which is Isuzu 4FB1 to my Kia Sportage but I find it very underpowered with only 1.8 L of displacement, so I decided to find a 2.0 L diesel engine and return the engine of my jeepy.

Hope someone could enlighten me ,Thanks..

If I were you, I would put back the original Kia engine.
