hey just wondering how it would be?
iv searched and found nothing

b18a1 pr4 block
with oem pr4 b18 rods..
and pr3 b16a pistons

what would the diffrence be from pr3 to pr4 rods
i have a pr3 crank aswell

let me know thanks

 

what happen to ur ls crank? the difference is the length on them between the rods

 

ok well iguess i should use the stock ls crank .... what rods / pistons should i build i want it to be able to stand a turbo when i install it later

 

you use a ls block ,crank and rods thats it

then you get some b16 pistons and get them put on the ls rods then take the pistons and the block to a machine shop to get it honed to OEM specs

 

awsome thanks..... how much boost do you think that could handle?
should i do eagle H beams and some turbo pistons?

 

That depends on how much power you want, how much you're willing to spend, and how long you want it to last. Picked out something to tune with yet?

 

well a ls block with b16 pistons your c/r will around 10.8:1 to 11.0:1 c/r with a vtec head it will be even higher

if you want to boost it go and get some eagle rods and some pistons like CP,JE,ETC,ETC

you will be looking at about $1000 if not more to build your bottom end and that for everything

 

yea i just dont know how much i can boost stock internals to..
yes im gonna swap a vtec head on aswell

i was looking at yes hate if u want egay at the eagle h beams and wiesco pistons
and 1000 bucks to build it up im willing to do it.... cause i was hoping to get a good head seat up and boost to like 20 psi .. my ls crank will be balanced and polished

as for tuning im not sure but i would get the set up tuned for 20 psi ...

as for the head i have a b16a1 pr3 head with skunk 2
valves
springs
retainers
turbo 2 cams...

would pr3 pistons and LS rods hold up to 20 psi??

 

thats not a really smart idea bro im doing the same build with out turb0 your compression is almost at 12:1 thats high a heck for boost
post some feedback
hp torque
etc
