35lbs on a 14b.

Re: how much boost can a b20 bottom end hold
 

you can push as much boost as you want on the stock block...the question you have to ask is how long do you want it to last? i wouldn't go much over 8-10psi (if that) especially if you're expecting it to last for an extended period of time.

i thought this was the place to ask questions????
thanks to all the pep's here that helped me with my question.
for the other people here yes i done some research. but i wanted to see what and average joe would say !!!
since im an average joe. i trust more what people have to say here.

260hp

Re: how much boost can a b20 bottom end hold
 

block b20
ls/vtec golden eagle kit
golden eagle rod h beams
pistons are wiseco lower compression
lower girldle installed so it holds good in high rpm
arp bolts for everything
t3 t4 turbo
b16 head
skunk 2 internals (for the head )
stock gsr camshafts
skunk 2 intake manifold
obx throttle body

i dont remember the rest let me know what you guys think of the set up

anything else i want to push around 350 to the wheels for now. later ill get sleeves on the block or maybe do the block filling (dont know much about it but i have 2 zc block from germany and a b18a so can try on those) but i need to wait see what the guy sais when the weather get hotter

maybe wrong, maybe right.

Maybe wrong, maybe right.

I'm going to say approx 1700 psi...




Are you getting this? Catching on yet?

Psi is totally dependant on they size of the turbo. 14b at 10 psi is a lot less than gt30 at 10 psi. It's all about how many CFM's the turbo flows.

Re: how much boost can a b20 bottom end hold
 

you mean is how soon the turbo will make boost ? i know there is math to it about how much boost a turbo will make.
what turbo would you consider for my set up ?

Re: how much boost can a b20 bottom end hold
 

no I'm not talking about how soon a turbo will make boost. i'm saying a 14b at 10 psi will make xxx hp whereas a gt30 at 10 psi will make zzz hp. 10 psi on one turbo isn't the same as 10 psi on another turbo. The two will make a different ammount of hp at the same ammount of boost. Telling us you have a t3/t4 doesn't tell us ----. Telling us you have a .xx trim t3/t4 with an ar. of .xx/.xx will tell us alot more. At least then you could READ THE ------- FAQ'S which will point you in the direction of learning how to read compressor maps. Then you could pick a properly sized turbo for your build. So in a round about way of answering the original question of this thread: Your block may be able to handle 2 psi or 200 psi depending on which ------- turbo you are using. Last point... don't listen to a god damned person when they give the standard answer of "8-10 psi" because they don't know what the ---- they are talking about. They are just telling you something that someone told them that they heard from someone that they were told by their brother's sister-in-law's uncle's wife's dad. :-*

and learn how to speak/type trying to read you ---- makes my brain hurt.

Re: how much boost can a b20 bottom end hold
 

.48 AR turbine housing and .42 AR compressor housing.
thats the way i write!!! my bad i write like a talk !!! all in one breath

Re: how much boost can a b20 bottom end hold
 

Way to dump a ---- load of money into a ---- block, that B20 siamesed sleeve ---- will crack in an N/A built. It builds up heat the areas where the cylinders meet, you know, the areas where the coolant can't do it's job.

All that crap and you couldn't just get a B18B block? I mean seriously the difference in the displacement can be had if you bored it out, which how the displacement is gained in the B20 block to begin with, I'm quasi-sure those cranks/stroke are the same.

And that's not even considering what B20 you have, because if you got the retard OBD0 block from a Prelude you are fucked. :1 :1 :1
