Just to verify....this was the NC Miata 6-speed(normally stock bolts to a 2.0 Mazda MZR/Duratec)
6-speed trans that went KABOOM whilst mated to the swapped in ecoboost?

Yep. Stock NC 6spd gearbox.

That's where we got the idea for the NC trans initially.

So, er, moving right along...

Is there any reason why a Ranger oil pan would not be workable with the Ecoboost? I do understand that it requires eliminating the balance shafts.

The balance shaft assembly weight something like 17lbs! I definitely took it off.
I skipped the ranger pan because it was cast aluminum, but it should work just fine.
Retro-Ford has a steel rear sump duratec pan, but it's $$$.

Good to know. I am probably going to be picking up a core Ranger engine shortly. The engine itself is FUBAR but the RWD-specific parts should be salvageable.

The downside is, it looks like for only a little more outlay relative to an Ecoboost + controls pack + turbo-specific necessities, one could build a really kickass 2.4l motor. 2.5 block, 2.3 crank, 2.0 direct injected head (apparently this is the best Duratec starting point), decent rods/pistons/cams, the usual intake and exhaust requirements, 330+hp naturally aspirated at sane RPM. No need for porting or valvesprings or other such expenses, either.

Well, I gots TWO RX-7s now, and I could source the 2.5 block from a Mazda 6 so I could claim it is a Mazda engine...

Is that still a requirement for anybody? I thought it was taken out a few years ago.

Exactly, assuming that the windshield crack rule gets rescinded.

I know the 2L NA version anyway has FoMoCo cast into it so I can't imagine anyone could identify a Mazda 3 2.5 vs a Ford Fusion 2.5 block.

The Mazda 6 engines seem to be cheaper, probably because the super cramped engine bay means they always have broken intake manifolds and timing covers.

You ain't seen "fun" until you seen a 3.7l Mazda 6, either. I don't think you could fit a finger between the timing case and the strut tower. Step 1 in replacing the water pump, or almost anything else, is "Remove drivetrain from vehicle."

There's Volvo bits on the ecoboost as well.

Like what? Do tell!

I wasn't aware that Volvo had anything at all to do with FoMoCo enginery. Mazda made the fours, Ford made the sixes, and Volvo made the chassis.

I thought, anyway...

Doesn't the Volvo 2.5L T5 share some with the Duratec??? Or the Duratec derived from some of it???

A quick googler... Wiki

The B5254T3 is a 2.5 L (2,522 cc) straight-five. Bore is 83 mm (3.3 in) and stroke is 93.2 mm (3.7 in) with a compression ratio of 9.0:1. It is turbocharged and intercooled with a power output of 220 PS (162 kW; 217 hp) at 5000 rpm with 320 N·m (240 lb·ft) of torque at 1500–4800 rpm. On cars with the AW55-51 automatic transmission, torque is limited in first and second gear.[131] It has VVT and uses the Bosch ME 9.0[132] engine management system.[133] Unlike previous designs, the turbocharger is integral with the exhaust manifold.

Adaptations of this engine were used by Ford, with power levels ranging from 220PS (217 bhp)[134] to 350PS (345 bhp).[135] At Ford the engine was called "Duratec-ST",[136] "Duratec ST"[137] or "Duratec RS".[138]

Applications:[139]

2005–2008 Volvo S40 II[104] badged as S40 T5
2005–2008 Volvo V50[104][140] badged as V50 T5
2007 Volvo C30 badged as C30 T5
2006[141]–2007[142] Volvo C70 badged as C70 T5
2005[143]–2011 Ford Focus[132] badged as Focus ST[144]
2009[145]–2010[146] Ford Focus badged as Focus RS[145]
2011 Ford Focus badged as Focus RS 500[135]
