The vq35de is listed as 142kg which is almost the same weight
as the lightweight Toyota 3sge which is 4kgs heavier as is
the Chrysler Dodge Hemi 2 v8 engine!
However 400hp atw with bolt ons in such a compact package
albeit quite wide almost matches a Hemi in hp yet more rpms
and shorter in the bay at least. Its really the Japanese LS!
There is 8kg that can be removed from using a billet style
flywheel/clutch, 5kg from no power steering pump and a little
more from other areas if using no vve timing mechanisms etc.
Prob 120kg is possible billet alloy mains and girdle but that's
crazy moneys to replace the already quality steel units used.
SR like most of Honda engines are beefy heavy sandcast blocks
but the VQ is pressure die cast making up for the extra rods
while crankshaft and head of the SR are also heavy items.
Atm saving up to get a vq37 and use vq30 front cover to eliminate
the vve (albeit less hp), good springs, headers & honda vtx1800 carbs.
Likely better rods as well as this was the only reason Sascha
on SPeedacademy threws a rod at constant 9k rpm on a stock vq35de
bottom end with bolt ons. Always dreamed of owning a high screaming
v6 like the old NA Ferraris of the 50s. 8500rpm will be nuts
and hopefully the carbs can make better sound than they are known for.
Hoping to fit this into an S10 silvia or Locost one day but cost of
vq37 here is about 650 usd as a base.
