hey everyone. I can get a B16 block for real cheap. But the problem is that its 1.6 liters!!(going into my 3rd gen integ) What i was wondering is how much of a hassle would it be to put the LS crank and rods into this block? One of my friends said that the block would have to be machined to make it work right but i dont know what needs to be fixed. I'm building this engine for my B16 head so i have pretty much all the time in the world. Also, what displacement would i be with this setup, would it just equal an LS engine? well, thanks in advance.:thumbup: i know you guys will give me some good info.:thumbup:

It would be a lot easier to use a b17 or b18c crank. Also the b16a has a better rod to stroke ratio so it would be kind of useless.

 

It would be incrediblly difficult, you'd need super short rods, so you have a rod:stroke ratio of around 1.4:1 (maybe even lower). You could LsVtec (use the B16 head on the LS block) that would be probably the best solution.

 

actually what u would really want would be the b18c crank with b18c rods, then get custom pistons from je, and have the pin moved up in the piston and uses a oil ring spacer, and it should work. im getting ready to start this project ive been working out all the numbers, if u bore it too 85mm with b18c crank, u get 1.978L of displacement, might as well call it 2.0L, if u manage to get a ls crank to work, and keep 85mm bore, you get 2.019L not much more displacement, and might run into some problems with the extra 1.8mm of stroke.

but im working on the numbers, if i could just get the differences between the b16 and b18 deck height i think i would have it all figured out, so if anyone has those numbers i would appreciate it.

 

the reason why i dont want to use my b18b is because i want to be able to swap it back into my car once smog comes. I can get the whole b16 block for a bill so thats why i asked. So the gsr crank and rods will work better? would i be able to just run the stock PR3 pistons in there for a little while? tia

need to check deck height with stock pistons in, the b16 block might be a little shorter, so make sure the pistons dont stick out of the block when ya put it together, and be sure to check piston and valve clearance

 

cool, thanks a lot for your help vtec
