This got me thinking: "Ford ZTEC motor puts out 180hp and ONLY weighs in at 70 odd kgs"

Which Zetec? Ford made so many:
* Ford Zeta "Zetec-E"
* Ford Zeta "Zetec-R"
* Ford Sigma "Zetec SE"
* Ford Kent "Zetec-Rocam" (Duratec 8V)
* Ford Duratec "RoFlow Zetec" (Mazda MZR)
* Ford Duratorq "Zetec TDCi" diesel

70kgs! That's light. Which engine?

That's my question too. I can only find Zetec-R 100kg/170hp (factory stock) which bests the famed Rover K-series (96kg/160hp)

A14 is 93kg 80hp
Toyoda 2ZZ-GE 112kg 180hp
SR20DE 139kg 140hp

the only zetec I know of is a cosworth made ford cast iron bottom engine for the UK market and unfortunately is not 70kg but over 120kg in fact its almost a 4age in weight.

My old bare unopened suzuki g16b was 52kgs with no ancillaries but inc waterpump
belt and some other mounts including oil. It managed 126hp ate with mild cam regrind, some headers and r1 bike carbs but now makes 132hp with 11:1 comp and sits in a sand rail in Port Fairy. The current owner is going to try and get the speedway midget head that was ported with bigger valves, titanium retainers and quality springs which revved to 11,000rpm using G10B bottom end at 1070cc and 59mm stroke crank, that made 196hp at 10,500rpm as raced by Dynomite performance.
The g16b engine also holds a world record for highest altitude run vehicle using a supercharger to help it in the Andes mountains with very thin atmosphere.

The lightest Nissan L4 engine is the MA10ET found in old march turbo and some exotic
race cars called the zaurus by nismo, they made 80-110hp and weighed 68kg dressed.

edit: correction the lightest nissan engine ever made as a 360cc v twin for the feather

What about the Ford Ecoboost 1.0 ?
97 kg dry and std 110-140 HP and 170-200 easy with the turbo swap from a 1.6 or what you like.

Problems just happen when we get into management...

No aftermarket ECU supports GDI :/ But with fac. management it could do with a re-flash
(Have been thinking about doing the swap ;) problems include finding a gearbox to mount it to)

a hayabusa is already powering a 1200 on youtube its mad

thats 65 or so kg all up including sequential gearbox with boost
probably 70kg for 400+hp atw so not too shabby
