New I-Force Engines from Toyota

New I-Force Engines from Toyota

Copying and pasting from another forum, that copied and pasted from another forum. No reason to believe none of this stuff isn't true...

Here are the specs for all UR engines:

DOHC, 32-valve, dual VVT-i, chain driven, roller rocker valvetrain with low coefficient of friction roller bearings, molybdenum coated pistons with anti-friction coated #1 and #2 compression rings, available dual fuel injection on passenger car engines with single fuel injection on truck based engines, second generation high performance, low friction F head design stemmed from the GR series engines. ACIS II/III integrated into the intake manifold, which continuously varies the intake runner length depending on engine conditions and detection of air mass within the manifold. Roller rockers provide more valve lift in performance applications than previous cam lobe driven bucket type valves.

1UR-FSE 5.0L 90 degree V8 with dual VVT-i (IS500)
1UR-FXE 5.0L 90 degree Atkinson cycle V8 with dual VVT-i (LS600hL)
Aluminum block and heads
Lightweight forged and sintered connecting rods for greater efficiency, revvablility, and reliability
Lightweight moly coated pistons
Forged steel crankshaft with 8 weight balancers
Dual fuel injection with air assisted port injection and unassisted direct injection
Larger intake and exhaust ports and slightly larger valves for increased performance
Performance tuning
Estimated power:
430-450hp
400-440lb-ft

2UR-FSE 4.6L 90 degree V8 with dual VVT-i (LS460, GS460)
Aluminum block and heads
Lightweight forged and sintered connecting rods for greater efficiency, revvability, and reliability
Lightweight moly coated pistons
Forged steel crankshaft with 8 weight balancers
Dual fuel injection with air assisted port injection and unassisted direct injection
Estimated power:
380hp
370lb-ft

3UR-FE 5.7L 90 degree V8 with dual VVT-i (Tundra)
Aluminum block and heads/Cast iron block w/ aluminum alloy heads (?)
Forged, high strength internals with 6 bolt main crankshaft bearing caps, fully balanced forged crankshaft with high strength connecting rod bolts
Large diameter forged connecting rods with heavy duty moly coated pistons
Single fuel injection - air assisted port injection for greater fuel atomization
High compression relative to other truck engines
First truck engine with dual VVT-i
Estimated power:
400hp
470lb-ft

4UR-FE 4.7L 90 degree V8 with dual VVT-i (Tundra, 4Runner)

Forged, high strength internals with 6 bolt main crankshaft bearing caps, fully balanced forged crankshaft with high strength connecting rod bolts
Large diameter forged connecting rods with heavy duty moly coated pistons
Single fuel injection - air assisted port injection for greater fuel atomization
Estimated power: (bridges gap between 1GR and 3UR)
335hp
375lb-ft

400 Horse And 470 Lbs / Torque?

Travis...we now need to swap this new motor in BEFORE boosting.

You wouldn't need bosting after that swap

Can I have that put into my current Tundra?

You only want the new 4.7? Pish. Upgrade to the max homie!

And get 12 city /16 highway? I think not... I'd like some semblance of decent mileage, even if it is pale in comparison to the tiny Corollas.

Heh. The sticker on the window of my truck said I'd only get 14 city / 16 highway. I get 17 city and 19 highway.

To have the power to out-tow my dad's 5.3L Sierra. ...screw it, I've wanted to shut that guy up about power since I bought the truck. Now we have something to ram down Craig's throat too about his damn Suburban. (Insider with Travis and Kris)

Boy, it sure reads like your post is really saying: "There's no replacement for displacement."

10-4 Good Buddy!!

I wonder which one of those V8s the hybrid will be based off of, if it will ever be released. I suspect the smallest (HP/TQ wise) of the group would be the likely choice.

where are you guy's getting things figures from? 400 HP ah Thats not what my source has stated try like 350 hp. Toyota has not released any details on the 5.7 liter iforce v8 on Hp figures yet..

Toyota has released the specs on the 4.6 V8 in the LS and GS 460's and those were right on, so there isn't really any reason not to believe the 5.7L figures. I got this info from another auto forum who said they got it from an insider in the auto industry...

Ah, the reliability and trustworthiness of the internet.

I think it is like a patient friend of mine says.

"Just wait and see."

I split your post out to it's own thread Connor. ...you didn't think it was worth another thread...but I did.

Fair enough. Thanks!
