i was intrested in putting in a b20 and of course turbo the basterd but my friend said something about the b20 block being iron and with these motors having problems with a turbo setup just woundering if i would be running into any problems.

 

which b20?
if your referring to the bastard b-series from the accord (b20a), then iron.
if your referring to a real b-series then aluminum.

 

you sure? i was pretty sure that a B20A was a aluminum block motor...but still have a closed deck... infact im 99.9% positive that a B20A is aluminum block with closed deck...

either way they are a Honda motor and in stock forum are gonna have issues with boost and shitting tuning...

B20A is gonna break pistons and rods

B20B/Z is gonna break pistons and sleeves

 

Ya all of the old school B20A2 through whatever, were closed deck aluminum blocks. The A20A from the US Accord was an iron block.


I miss my Prelude.

 

the b20a from the prelude was aluminum. from the accord, the A20 and JDM B20 blocks were iron.
