ITR bottom end internal on B16A block??

Hi guys...

I need help asap...
I have EG civic with SiR II engine on it..and im rebuilding the bottom end with B18C (ITR) internal.
Can this be done with the actual B16A block..?

Cos at the moment i got the B18C crank, rods and piston to be fitted in.
But strange thing happened. As soon as we trial fit them, the piston stick out from the bblock.

The crank that i got has longer stroke...is that the right crank for B18C?
The rods that i got are longer thatn the B16A...is that rite? ( i doubt it it wasnt rite!) :confused:
The pistons are rite...cos it fits perfect...

Any help in regards to my question would be greatly appreciated... :)
and if any of you have any opinion how should i have done it....please let me know... :)

oh yeh...any pics to compare B16A parts and B18C would be good... ;)

B16A block has a shorter deck height than a B18C block. A B18A or B18C block will work.

your better off sourcing b16b internals (ctr) than b18c internals (itr)...

oh really...?
so there's no way i can fit ITR internal on B16A block?

cos my intention is to get 1.8lt out of that...

thanks guys...

if i get the B18C short block..would it be an easier way to do it? consider i will fit the B16A head on it...?
would the head fit straight bolt on?

Uhh, the B18 internals are for long stroke, so of course they will stand above the B16 block. The B16's revvability is quite good already. If you want to get more capacity out of it, you'll need a B18 crank and a shorter rod. Even this way, you won't get 1.8L out of it.

That's still wrong as the CTR (b16b) uses a b18c block.

I'm surprised you're rebuilding an engine without knowing the major differences between a b16a/b18c block!?!?

This is wrong, displacement IS governed by Crank stroke...

i was sure the b16 head is almost identical as the b18c block from the ITR. (checkout the forums for the poor man's type R)
The only difference between then is the lower block which is slightly high by a few mils.

The b16b uses a destroked b18c block

I think you mean b16b is a destroked b18c

Yes, but with a B18C crank and the unknown long rods that he had, the pistons were above the deck at TDC, so shouldn't he use shorter rods in order to keep the pistons below the deck while still increase displacement while using the B18 crank.

from wat i know there certain parts from the b18c u could use but cant remember which parts u can use
