no, b16b (ctr) pistons are 81.5mm b20 pistons are 84....

go with b20 + turbo, more reliable and less headache to piece it together.

 

Yeah but the headache comes back 6 months later when you have a blown motor

If you go b20 turbo you better make sure you do it flawlessly, and make sure the sleeves are set... otherwise your only gonna get 500 miles out of it

 

ctr pistons come in stock 81mm and overbore of .25mm

 

i had both a cam'd B18B and now a JDM B20B. the B20 > cam'd B18B.

 

im strongly considering a b20 instead of rebuilding my b18b... well id be rebuilding the b20, too.... the 133 ft/lbs is a turn on

 

posted twice, you can delete this if you want to... h-a.net is giving me hell tonite

 

Bit of advice. If you wanna do a B20/VTEC right it's damn expensive. I got into the project and didn't realize how much it was going to cost to do it right. You don't want to drop a few grand into an engine to have it blow up, but in order to make last you have to drop a few grand more into it.

wouldnt the b16 head out of a Civic Si and a CRV B20 match up no problem? they are both VTEC motors....cept the civic is DOHC VTECand the CRV is iVTEC

 

Nope the b20's are not vtec

 

B20 doesn't have iVTEC :eh:
