Building a Turbo Duratec. 2.0 or 2.3?

Engine -$550
Rods+Pistons -$800
Gaskets and bolts -$400
Adapter and flywheel -$400
Clutch -$350
Megasquirt -$700
Turbo manifold -$350
Injectors -$200
Misc -$400
Oil Pan -$400-$600

$4750 from where I sit now roughly.

Its still lighter and a few decades newer in design.

Don't be so certain about the 'few decades" newer design. From what I've been told Duratec was an old Ford/Cosworth deal that got shelved , and looking at the numbers and sizes of things, I say it's a very early 90s design...(journal sizes, bigger bore etc)
So while YB is a mid 80s design it was not a mid 80s grocery getter, it was designed to beat 240 Volvo turbos in BTCC and WTCC , so it was quite an advanced design....

Exactly, what can I get in the junkyard?

The YB is cool, but I am kind of wanting to prove the Duratec's worth.

They seem to be alot like Folvo conversions a few years ago, they are just now getting to idle videos of Folvo conversions of the Lima engine.

Finally I can subtract the cost of clutch and adaptor form the Duratec cost for comparison sake, because I would still need a YB bellhousing AND a clutch.

Nevermind that the Duratec comes with tech from the junkyard like coil on plug and even VVT if you wanted to play with that...

I think the Duratec is the way forward for the common man looking to replace the Lima. especially since if you screw up, parts are cheap to start over. How much is a YB block and head if I launch a piston into the head and wipe out a bore and the valves/head in the process?

Interesting article about a WRC Duratec:

LINKY--- START ON PAGE 18

Im looking into using a 94 Mustang T5 but I am concerned because of the bell housing design vs the 79-93 style.

Bare aluminum is new style black on is older style.

Maybe a cheap and simple input shaft swap and use a 87-93 bell?

What was that turbo ranger guy using?

A t5. Im just worried about the stupid vent thing on top of the newer bell housing hitting my drive tunnel and extended"sump" on the newer bell housing hitting the sway bar.

I might be over thinking it.. and a grinder/hammer would likely solve any clearance issues I have?


Stupid XRs...lol

2008 or newer for the forged crank i would go with 2.5 no internals just tune
and turbo you can do 300 no problem. for now use a ranger box dirt cheap and
more than strong enough that would cut you the bs out for now and it would
drive fine build a motor wile the cars running a buttery smooth motor with proper
turbo even if you did not make 300 hp it would still be more than you need for now
with how well the power delivery would be.

dont go nuts just go

i personally have a sickness for the newest duratec v6 300 hp no nothing needed and
theres a trans out there and just mega squirt plumbing and mounting would be done.

If one was going to build a turbo Duratec, would it be better to start with a 2.0 or 2.3?(In other words, how would YOU do it, with YOUR money?)

Yes its for a Xratty.

Mind you, you've qualified this with 'turbo' so here's my final answer for the moment.

2.0 Block
MZR 2009 Miata forged crank (for the 2.0)
Forged pistons and rods
2.3 Ford non Ranger head with 2.3 aftermarket cams
2.3 intake
Fire breathing turbo with some way of computer controlling the fuel/air (a 'tune'? megasquirt?)
MTX-75 with clutch plated diff

That's how I'd start it with my moolah for rallying. Sort of. Honestly, if I was to start an engine for rally for the xratty, I'd have to seriously consider the lima/pinto thing with a volvo head on it. It makes just gobs and gobs of power under pressure and I don't think there's nearly as much electronic futzing as there would be with the xfer of a wiring harness, ECU, keys etc of the duratec.

That being said, I am starting my daily driver project with a 2.3 non ranger head with the intention of keeping it NA even though a turbo in the long run might be more efficient. But again, its my moolah and its not going to be rallied. Its only ever going to see tarmac and its *got* to last me a few years.

ford duratec and mzr cranks do not mix! all 2008 and latter duratecs are forged cranks
stop with the internals and bla bla bla get all the accessories and the car running in stock form
and turbo it with a 2.5 you will make 300 hp safely and go from there in a motor out side of the
running car

there has been gt 35 installs making over 430 hp on a stock 2.0 focus motor not safe but works
tone it down get 11 psi intercooled and a good tune you should make 280 hp on the 2.3 and 265
or so on 2.0 bone stock duratec's

Neverminding the fact that everyone has an opinion,

"It has an aluminum engine block and an aluminum DOHC cylinder head. The cylinders are lined with cast iron. It uses SFI fuel injection, has 4 valves per cylinder and features fracture-split forged powder metal connecting rods, a one-piece cast crankshaft, and a cast aluminum or reinforced plastic intake manifold."

2009+ Miata cranks are forged and work.

Duratec Forged 2.0L Crankshaft Genuine 2.0 litre Forged crankshafts for use on your Duratec. It offers lower weight and reduced inertia over the crankshafts used in other 2.0L derivatives of the Duratec engine. This is a brand new crankshaft, not a take off part or used!
Item #: GP-2.0Forgedcrank
Manufacturer: GPWerks/Mazda

There even stamped FORD (FoMoCo) before they ship them to Mazda.

But hey, like I said... just my opinion since he asked what I would do with my money. Even though outside of the thought exercise I wouldn't because I don't need it.
