Anybody have experience with the Mazda 2.0 RF intercooled turbo diesel? Know anything about them, good or bad? It's an option for an engine swap in a Suzuki but I don't want problems.

Hi Cj
Have had nothing to do with the 2.0L intercooled turbo, but have had the R2 non turbo 2.0l and found it to be the worst motor ever put on the face of the earth!!!.
Major head issues. My advice would be to tread carefully.
Cheers Axle.

Thanks. The R2 is a stroked RF and I have heard about cylinder head cracking. It seems to be caused by overheating due to water pump cavitation. I have a couple of possible fixes for that , one being a cast iron head I have come across. Other options include slowing the water pump down and adding an electric pump as a booster or just changing to a better water pump. Any other things I should be aware of?

The cast iron head would definitley fix 90% of there probs, Your also right about the water pump, would need to address that issue as
well, The crank shaft pulley was known to come looseat times, although i didn;t experience that, probably a torque issue on the bolt. The funny thing is the early 2.0 l motor had a cast head, and was not over head cam, have seen 900,000ks run up on one without any issues, its amazing how companys can stuff up at times.
Cheers.

The RF is a venerable old diesel nowadays, having first being introduced in 1983 and currently reappearing in the Mazda6 Diesel as the RF-7. 24 years is a long production run! Suzuki has used the RF before in the Diesel Vitara, as
well as Mazda using them in a whole variey of cars, utes and vans in N/A, Turbo and Supercharged versions. As long as the engine is not overloaded (you're not planning on towing a 30' van with all that torque?), the RF will give excellent service in a light Suzuki.
