Ok np.

Has any1 tried this:
B16A crank (77.4 mm stroke and the mains can be align honed for better bearing crush) with LS rods (137 mm rod length) in a CRV block (84.5 mm bore when bore-honed) with a GSR block girdle added to give a strong 1736 cc, an oversquare layout, and a 1.77 rod ratio.

Honda has done the thinking for you. Want a solid 1800CC? B18CR.

What's the point in reducing the cylinder side loads if you have to halve the wall thickness to do so. The B18CR proves that the rod:stroke ratio is over-analysed.

Waste of time/money and for what so you can have a 1.7 litre people get way too creative and stressed over rod/stroke ratios

String is right the B18C has a rod/stroke of 1.58

hey how come u went b20 instead of boaring out a b18c to a 2 litre? Apart from cost?

Too much eefin around the B18C sleeves can be bored 82mm max and thats 1.9L and it doesnt give you any room to play around say u scratch ur walls , u will need new cyclinders walls or new block

cool no worries. I'm heading down the b20vtec road i thought about going down the K'series road but i've been told its a better drive then the K's.

i dunoo who told you that, K Series is advanced technlogy, far superior, only reason holding me back was my budget..

But with enough work done to the B20VTEC you can get it around the 145-150kw range and you will have a very quick package. Mind you will need good compression say in the 11+ and Hi lift camshafts. Remember power is in the head, so do all the nessecary upgrades id recommend CNC the combustion chambers, port n polish etc
