Why Toyota sucks and Ford is awesome

The 2.7L ecoboost appears to be some hybrid block, i'm not really sure what this means, but it's how ford lists it.

First part is the block, second is heads.

Compacted graphite
iron-aluminum/
aluminum

The 3.5L ecoboost is listed as Aluminum/Aluminum.

Autoweek gives a brief explanation of the hybrid block. Seems like some diesel tech is migrating over. The plastic oil pan weirds me out though.

Plastic valve covers and intake manifolds have been around for a while.

Only issue with a plastic intake manifold is if you have a backfire in the intake; seems like it'd be slightly less resilient than it's metallic counterparts.

The linerless cylinder block is compacted graphite iron (CGI), Ford's first application of this material in a gasoline engine. Proven on the latest generation diesels and some racing engines, CGI is a high-strength material with excellent heat transfer properties. Compared with grey iron, the CGI cylinder block offers approximately 75% higher tensile strength, 45% greater stiffness and roughly double the fatigue strength, with excellent dimensional stability, durability, and NVH damping characteristics, according to Ed Waszczenko, Ford's V-Engine Design Leader. He noted that Ford also used CGI in the 6.7-L Power Stroke V8 diesel (which influenced the design of the 2.7-L's block, offset I-beam connecting rods, reinforced-plastic oil pan, and pistons) as well as in the 2.7-L light-duty diesel co-developed by Ford and PSA for European applications.

Impressive stuff. I'd still pick the v8, for now.

LS motors all have plastic intakes, i've never heard of any issues. I have seen some exploded ones though from a big back fire.

You might have issues though if your motor is exploding intake manifolds lol.

The mustang is sporting a plastic intake as well.

My ex boss at the glass company bought a 1st year design of the chevy van in 97. the plastic intake lasted just long enough to be out of warranty. His van also had issues with the electronic dash. He did not have the problems with the tail light grounding problem that you see on a lot of them.

The plastic intake on the Buick we had gave us nothing but problems with leaking.

Replaced it twice. Sold it shortly after the second time.

Was it the 3800 motor? They were known for having lots of intake manifold problems. Pretty much every manufacturer has problems like these at some point.

Heck even my co-worker just had a new shortblock put in his Civic because of a cracked block, it had 70k miles on it, and people rave about Hondas reliability, lol.

sadly yes. That car was also a pain in the butt to work on. I hated it. The worst part of all, the car ate a 10mm with my extension.

They are if you don't drive them like a race car. (or as a race car)

Simon? (sorry if that is poking)

Anyhow, to the comments regarding plastic intakes... My third generation Fit has a plastic intake and maybe even valve cover. But I am only at 9K, so time will tell on any issues with that engine. It is the latest development of the L series with DI and i-VTEC.

The power on all these is plenty all the time to tow anywhere. You just won't tow at 70mph. Slow to 60 and you'll handle any grade.

You are approaching this from the wrong perspective comparison shopping numbers. Any of these trucks still have a surplus of power. Look at the chassis and suspension, but most importantly which has the biggest widest brake rotors.

I'm sure each has four or more gears too. That's just as big a deal as power up a steep hill.

my brother in law,has a 4.7l toyota tundra 4x4,i think its a crew cab.He says its a pretty good truck.Why not get a tundra or ..Nissan is putting a 5l cummisn v8 diesel,in the titan.If you are ok with big..Our 7.3l turbo diesel,tows like a tow truck.

Seriously, I towed the Miata on an open trailer with a 4.6L F150. 220hp/265ft*lbs. I towed doing 75-80 on the highways as well. Grades weren't fun though.

However, I upgraded to a F250 with 570ft*lb of torque and it's night and day. I actually have to check to make sure the trailer is back there.
