B16A bottom end + ??

[DomenEK]

I'm starting to warm to this idea of a B20B bottom end, and a B16a head.....Obviously the B20b would give it more torque through the midrange, and the B16a head allows it to scream like a true vtec monster?

How do these hybrids compare to the b18c/B16a ones?

[barefootbonzai]

Very hard to answer a question like this. What exactly is it that you wanna know? The obvious would be the b20 one would have more torque.


Are you seriously gonna do it or just asking about it for now?

[DomenEK]

Asking about it for now. When I get a bit more financial, I'll be looking more seriously, but for now I'm just gathering ideas....

man been searching on this topic for yonkers now so i thought i'd add some questions to this thread:

B16a Head + B18b Block
Displacement:
CR:
Avg Price of Block:

B16a Head + B18c Block
Displacement:
CR:
Avg Price of Block:

Rego/Engineering - If the displacement increase is less than 15% can it simply be blue slipped and engine numebrs changed with RTA?

What is the rule of thumb for B series CR. how many CR is 1mm off the head/hg worth?

Where can those CTR pistons be sourced?

yes.

What is the rule of thumb for B series CR. how many CR is 1mm off the head/hg worth?

10 thou = 0.2 (verrrry approximate!)

Where can those CTR pistons be sourced?

anywhere you get performance honda parts.

^^^thanks for all that +rep for the straight answer!!! lol whats with the message you get thoguh hahahaha!!!

now i have experience opening engines but have never opened a Honda... would like to attempt it myself... 1 last question then... where do i tap for the oil line?

don't wanna get flamed though... been searching this and all motor thread for yonks for various info.. if i'm searching for the wrong things give me a hint.... i know how forums are with noobs.

***EDIT***
also just checked EG5's page.. good prices.

IF the b18b block required honing what would be the expected displacement for the B16b 0.25 oversized pistons if non oversized is already 1834cc?? will obviously put me over the 15% threshhold though...

[dsp26]

^^^never mind... thanks for the calc... will have a play with it. thanks!!!


***EDIT***
B16a Head + B18b Block + B16B pistons oversized (assuming 0.25 = mm)
Displacement: 1846cc
CR: ~ 12:1
Avg Price of Block: $300-500 + $500 (pistons) + $250 (oil line etc)
