i have a b16a2 block and im planning on getting some 84-85mm sleeves. now if i come across a b18c1 block would it be worth it to get the b18 block and put 84-85mm sleeves in it and then put my b16 head on teh b18c block? how much of a difference is it between the two blocks with the same size sleeves? but i am gonna stay with the b16 head since it flows better than the b18c head

 

well instead of having a 1.8L, you would net a 2.0L setup, that is built...

Depends on what your setup is... and what your plans are...

if the motor is out.. or not... ex.. ex.. ex....

search is key...

If your boosting alot... I wouldnt go over 83mm bore... and since you have a Si... judging from your name that is... Id pick up a b18 block and sleeve it to 83mm.....

 

what do you guys think about a b16a2 head on a b18c1 block? i havent read about that set up on here and i did search

 

The head choice is all up to you... We really run either but more commonly the P72... Most flow charts will show you that the P72 cylinder head flows better up top sacrificing a little midrange where as the PR3 does better midrange but loses up top... You know me, I'm all for the B18C... The the same compression, etc. the GSR will support a bigger turbo and is capable of more output than the B16A... Just my $0.02 again

 

haha, i know you gz guys and the b18c. ill be keeping a look out for a b18c block. its just ive been told that the b16 head flows better than the b18c head so thats why i asked

 

how much power do you need? Keep the b16a, you can easily make alot more power than you would ever need...

 

If your going to sleeve anything, get the b18 block. Thats my current build up right now. B18C1 bottom end w/ a ported B16 Head = Type-R set up minus pistons and cams. Should be a excellent set up sleeved to 83mm

 

b18 has a main bearing girdle, and i think the water pump is different.

 

VTEC water pumps are all the same... No biggie tho...

I was under the impression that b16's had main girdles also...at least I thought so.

 

Yea it's actually only the B18C/1/5 out of the B series motors...

 

i might be able to get my hands on a b18c5 block, how would this go with my b16 tranny, and my b16 head for fi set up, i would get 84mm sleeves, rods, and pistons. is the stroke the same as a gsr?

 

dont get a b16 tranny. get a gsr or type r tranny and maybe a lsd if u got cash.

as for the gsr block and si head...great combo!!! :thumb:
i would say, in my mind its the perfect combo! i think its more reliable then ls/vtec

 

well i already have a b16 tranny with a quaife. so the itr block with the b16 head is just like the gsr block and b16 head? thats what i wasnt sure of

 

They are basically the same block..... the internals are what seperate them....

 

ok i know about the pistons and rods, but is the stroke the same?

 

the block i found and am interested in is a jdm itr block, is there a difference between that and a regular itr block?

Same stroke, same displacement.... all B18 vtec blocks have the same displacement.....

just crank/pistons/rods vary from motor to motor.... There is not much difference between the "JDM" and "USDM" ITR blocks, except for slight compression differences.

 

alright i couldnt find the jdm specs so i didnt know, thanks man, the comp dosnt matter since ill be putting other pistons in there. thank you

 

is it true the itr crankshaft weighs more than a gsr? if so is this a disadvantage for fi?

 

Yea, the ITR crank does weigh a little more than the GSR as it has larger factory counter balances... You're not going to notice any difference either way so it really doesn't matter... Just have your entire rotational assembly rebalanced once you get your rods, etc and you'll be set...
