We've all heard chatter on the internet about cracked blocks and cracked heads.
But not all of these are destined to fail from casting defects.
We've 3 at work that were destroyed by extreme abuse (no coolant or overdue oil change)
Once they get critically hot they blowtorch the sleeves between cylinders, which occurs when they're driven home after a coolant failure (pretty masochistic)
Yet none of these displayed cracking on head or block in the usual spots.
I'm actually quite suprised at the engineering parts in these, they're a generation different from other suzuki motors.
Still expensive to aquire (owners of $30k plus vehicles will spend well to replace an engine, and there's so few on market to use as donors.. J24B engines fetch a premium price wrecking)
[-o< Eventually I'll get one of my own to play with

Be interesting to measure across the face of the block and see if the liners have dropped like they do on a overheated M series

can see theyve gone back to alloy bottom section rather than cast iron?

Suzuki should have made it more like the G13b or even the g16b closed deck
(the best and only good thing about a g16b design) where the cast iron sleeve
is helped by alloy sleeve keeping things in place and helping heat issues

even Mitsubishis new evo blocks seem to be a better units than the Js

Not hard to add some bore bracing to match evo design.
Suzuki's j series "B" type has cast in ductile steel mains as part of the alloy cradle (best of both worlds) but biggest thing for me is a dressed engine is 110kg...

Thats a beauty on the craddle maybe Suz will Evo the top end a tad or at least use some of the Hayabusa combustion chamber and piston design to blow Hondas away for ever :D
Emission can be controlled in so many ways its a shame the bike department doesnt get a nod to 320hp the J series in a S2000 sized special edition AWD cappuccino called the Quad Xpresso all composite body :lol: :mrgreen:

I've been told suzuki designs engines, then releases them as production form at 40% output to make them durable, this is kizashi is rated at 131kW from factory, then the original design has been detuned from 183kW n/a.
That's 250hp in old money, so tuning and cam change should bring that back, not to mention that a turbo charger can effectively double the volumetric efficiency..
So a sorted turbo J24B on paper could be effectively 400hp+ much like an Evo.
That's why I'm fascinated by concept of sorting/tuning one of these 8-)
