Thanx much.. Looking forward to hearing what the difference is.. Also, would you know if the Focus 2.3 head has the same specs as the 2006 and later Ford Ranger with the 2.3 Duratec.. I'm planning to use the same setup N/A in a RWD configuration and would prefer to use the Ranger top end as it would already be have the necessary plumbing and accessories.. I'll be changing the cams to either Crane or Crower stage 1 units along with the associated VS kit as the car will be running ITBs and an MSNS3 for management..

I can't find specs online, so I'll need to get someone with a 2.3 head to measure their intake ports. I can't interpret the castings. I'm not sure what LO 05 means on the end of the head, even though that usually represents the displacement. If you can measure the other head you have when you get back to your garage I'd appreciate it.

Not dyno'd yet but with the Coswroth style IM - port polished head, and smoothed out TB i suspect she will do 180hp at the crank on race gas. Compression calculates at 11:1 or so - hence will only be running race gas to try to eliminate detonation.

Axles go back on this weekend - will post some road test / BUTT DYNO vids

sounds amazing to be honest

ps. NOT first start - ran it before i got the camera on

Since the 2.5 combustion chamber is the same size as a 2.0 head, I see no reason why the compression ratio would be altered. As long as the cylinder bores are good I'll be using P4-DU875-N2 Supertech 10.4:1 pistons. I actually have two sets of these at the moment after being duped by another member into thinking I was buying 88mm Supertechs. That's another story.

The 2.0 block I'm using is from my original motor that blew a ring landing. Amazingly there is no apparent damage to the cylinder walls or valves. All the loose aluminum bits were in the oil pickup tube, and probably the oil filter.

As far as progress, I'm still gathering last-minute parts. I'm focusing on house remodeling at the moment and will come back to this soon.

I think you're getting these threads crossed. I'm using a 2.0 block, not a 2.5. That would be MainiaxMotorsports.

Your messurements of the 2.3 ports are right. If u flip the head upside down there is a stamping that says 2.3 on the exhaust side of cylinder 2 just below the port looking up at the bottom of the head

Sorry 2013 ended up being a house project year. I'm hoping to get to this in late spring, after I renovate the bathroom.
Since I started working from home I don't have much enthusiasm for modifying a car I never drive. I think I put maybe 100 miles on it in 3 months.
