Default best b block for aebs sleeves and mad boost?

id take it that the b20 is the best to go for because of the 2.0 but any info would be great like 1.6 bored to 2.0 sounds unlikely but id like ideas. thanks

Any B Series w/ sleeves can be bored the same as a b20. A b16 would be different displacement but, You can take a GSR and put 84mm and have almost the same displacement as a B20. My B20 sleeves cracked and AEBS said they couldnt sleeve it. I guess the cracks in the sleeves ran too far down and they need part of the sleeve to install theres. I went with golden eagles. AEBS suggested getting a B18 for there sleeves as b20's need a little different type of sleeve. Just bore a B18 to 84mm and you have the same displacement as a B20.

Well a b16 w/ 84mm bore I believe is around a 1.8L But with a awesome rod/stroke ratio, would be quite a sweet little motor. A 2.0 will get you more power and torque.

so with the 1.6 what crank and rods would i use to achive teh 2.0 with the 84mm bore. (that bore doesnt affect how much boost it can handle does it, since its such a large bore, thinner walls ?? i dont know) thanks again

With aftermarket sleeves they can safely be bored to 84mm, in some cases even 85+mm bore, depends on manufacturer. If you went with aebs sleeves they could bore the B16 to 84mm and you could run high boost. Also if you are totally building a block why not go with a custom crank and custom piston/rod ratio. I think thats the best way you would get what you are looking for.

FYI for everyone. If this is the case where you cracked a sleeve so bad where you think it's un-sleevable---then think again. The new Darton closed deck design uses different specs then the originals. These new ones are actually beefier on the OD of the sleeve and requires just about all of the stock aluminum water jacket sleeving to be removed for installation. Keep this in mind next time your ready to turn that old cracked block into a planter.......or you could just send it to me for free

i wanted to know what combinations to use to get more displacement... anyone else?
so by using b18a crank and rods in the b16 with a 84mm bore what does that bump the 1.6 up to?

2.0

the b18a and b20 crank and rods are the same. the b20 gets its extra displacment with the larger bore. im not sure if the crank will clear in the b16 block tho. i dont think you can b/c the b16 block is shorter than the b20/b18. the deck heights are taller.

If i'm not mistaken a b16 w/ 84mm pistons is a 1.71 liter. anyone know the math for sure??I'm going by my piston build sheets.
