I know that b20's have week cylinder walls, I have yet to see where they crack at so i'm not sure if blockfilling will do any good. I just thought it would be worth a shot throwing it out here for some opinions. If it's not worth even doing then I'll just do it n/a with itb's .

you wont be able to run it longer that about 30 sec without overheating!!! Block filler, fills the entire coolant passages

Shootinfor6s

i wasnt planning on filling the entire coolant passage, you put a plug in the water pump hole and fill it up to the top of that point with salt, and then put the filler on top of that, then using the head gasket as a template to drill holes down into through the filler.

you would be better off sleeving your block. alot stonger and no overheating issues. but it's totally up to you.

search and you will find this always ends in conjecture and controversy

Shootinfor6s

no prob, i think i'm gonna just do a n/a for right now till i get my b18 back from being sleeved

worst mistake to do this cheap ****

why

bc it covers the parts where colant is most needed ( top of the cylinders ) , that where the combustion happens so there for it must be well cooled

thebigone05

exactly and block filler does not disapate heat as well as aluminum

Heat at the top of the cylinders on a b20 isnt that big of a problem. If you look at all the aftermarket sleeve designs they usually block the coolant at the top of cylinders.

To the OP
you can still crack the sleeves on the N/A motor.

YEA BUT THEY are still lots and lots of room for coolant to flow not like a filled block
stop being damm cheap and get the dam block sleveed

i'm not being cheap, i'm one of those guys who like to push stock motors to their breaking point. I've done it before on other motors that i knew more about. that is why i came on here and asked peeps opinioins. i've got my sleeves on their way to bore out my Ls block out to a 2.0L. and i'm already workin on the itb "tank" for the turbo and piping. it's gonna be a lil bit different setups than what you normally see. i appreciate all the input.

thebigone05

I did'nt think you can run ITBs with turbos, you would'nt be able to feed each tb correctly, also wouldnt you have crazy boost leaks

vtecmissle

they turbo plenty of busas and other itb motorcycles.

thebigone05

i was foresure they converted them to single tb??

Just checked and they are boosting with ITB's interesting!!

Shootinfor6s

if im not mistaken on here is where i got the idea from. there is a gsr with a "log" style collector that bolts to the face of the itb's it's pretty wicked looking actually. tony the tiger is running a setup similar to what i'm talkin about.
