Even if the ka block was stronger when have you heard of a block failing on a car thats gonna be daily driven. Honestly people like you sound way to familiar "I like the ka-t because its a cast block and its a 2.4" some times i wonder what goes through you peoples head same as i wonder if those hondas guys really think they look cool with there stickers and euro tail light putting you on the same level, and as for the 2jz's and rb's holding more power its not because they are cast...

green_machine said:now for the iron block... iron is stronger than aluminum. aluminum is lighter than iron. With high horse power and without a solid deck, walls can easily break into the water jackets. You dont have this with iron blocks because the metal is stronger. However, sr's are solid deck aluminium with iron sleves. so forget this argument for sr's. A solid deck is a solid deck unless you have like 800 HP.
now for the 2.4 L. there are stroker kits for sr's. obviously some SR owners want extra displacement because it is better. but this comes at an even worse Crank/rod ratio than the ka. You need big bores, small strokes, long rods. This sadly is not the best points for either nissan motors.
if i had the money i would build both with the same budget to finally settle the argument... that sounds like a good idea. please contribute. send monet to: 1234 nw 56 st.
the mod's should just make a new category...for sale, off topic, technical, ka VS SR...etc and post this and the other 1 million threads about it
well said But stroker kit's pretty pricey in the area of $4,000 from crower- $9,999 for apex-i's kit. the apex-i kit is 4 a 2.2L strokegreen_machine said:ok first the honda cracks.. nissan will never make a NA motor that can touch the past 5 years of honda.

green_machine said:Comparing a SR20VE to a k20a? K20 - 210 hp. the ve is still good
green_machine said:Absorbing heat in the combustion chamber is not good for HP, but in the block to dissipate heat it is. So the SR has the best of both worlds, iron sleeves and aluminum block. however it warps easier with overheating.
In an optimal engine all the heat will leave through the exhaust valves and into the air, but that would be an 100% efficient motor which doesn't exist.
The SR is better... but not that much better, and the ka has .4 liters more of displacement
