RF turbo & R2 mazda diesel

[yellowjip]

What do you guys think about these engines? Ive driven a mazda R2 wrangler ang lakas niya humatak kaya nya arangkada in 2nd gear.daig nya wrangler ko na 1L lagi 1st gear arangkada.May 4wd drive ba nito?

meron ako dati nung surplus na korean jeep, ROCSTA, ang engine nya R2, 4WD un!

I believe the old Kia Sportage 4x4 surplus uses Mazda 2.2 Turbo engine.

It could be using the R or F series.

RF Turbo is 2.0LT
R2 is is 2.2L

i believe ito rin ang engine na naka mount sa mga vitara na diesel na nilabas sa EU. May mga nakita ako sa Banawe nito last year.

Ok kaya ang rf turbo sa wrangler?meron ba ito available sa surplus na 4wd?mas malakas kc ang rf turbo 85hp compared to the r2 69hp.

i guess, may surplus yan. here in davao, ive seen a lot. i think, its originally mounted on rocsta.

I'm looking for the same wiring harness of the R2-turbo engine for its transmission. According to the owner of a Bosch-certified diesel engine service center, late-model R2-turbos that are fitted with an A/T has electronic controls that affects the injection of diesel fuel in the engine, depending on your vehicle's speed. Without this wiring, the injector runs on safe mode which lowers it's performance because it injects "richer" air-fuel ratios. I've been looking over the net for OE replacements or wiring diagrams at least but I've found none so far. Any of you have copies of witing diagrams for these engines? Share naman! :-)

I have an RF-Turbo engine originally fitted wit AT, actually we have disregarded those electrical wires to the engine except the one concerned with cooling system. You will also notice those vacuum hoses, the one that connects to the top of the Injector is the Turbo Boost which adjust the richness of the injected fuel related to degree of Turbo boosting.

I bought a new set of injector noozzles, advanced the timing, and attennuated the fuel injection to get a more economical and minimal smoke operation. To make it more precise, you have to use a Dyno equipment.

I also disabled the EGR and and installed a Crankcase Ventilation Catch can.

I mean Turbo boost compensator.

I always thought those compensators were for altitude, to cut the smoke-belching while driving uphill. Disabling the EGR also leads to improvements in fuel-efficiency and uphill driving.
