hi guys i have a b16a and i want to change it to 1.8 litres.

What is the best way to do this if i have access to a b18c5 or b18c motor to use as parts?

 

anyone?

 

take the c5/c's crank and stroke it

 

certain company's make stroker kits, look into that.

 

If you have access to those motors then use one of them. Don't waste your time with a B16 stroking it.

 

its not that, the b18 is not a whole motor, the pistons and rods are being used already, but have acess to the rest of it...

Then specify that.

 

there is another thread in this forum where a guy has pics of his special pistons and used with the right rods in a sleeved 84mm bore B16 it will yield a 11.x:1 compression 2.0 liter motor.
without a deckplate.

nice huh?
the thread has pics so that narrows your search a bit.
other methods are stroking using a special crank and rods and you can also sleeve it to a larger diameter cylinder bore like 84mm.

 

if the block is only missing the pistons and rods then just get some new rods and pistons, and u can put you b16 head on it ! way cheaper then stroking the b16!

 

if you have access to the B18c block use the block and purchase aftermarket rods and pistons........sleeve it or just plain bore and hone it....you have many choices that you can go with....give us a call if you need anymore help........

that's almost exactly what i was thinking.

why work with the B16A block if you have a B18C block and crank to use??

choose some nice rods and pistons for the bare B18C1/5 block, whatever suits your needs.

 

if i wanted to get more displacement from my B16a I would

a) bore it out to 85mm to make it a 1.8, at the same time keeping that lovely r/s ratio of 1.74

I would stroke it with a jun or toda but it cost a lot and also the new r/s ratio with the toda kit would be 1.54...(like the LS/b20) but the great thing about it is that it is super balanced in everyway so that it does not compromise with revablity issuse.

 

A B16A crank makes all kinds of no torque. The best way to go is get a B18C or at least a B18A/B block and send it in to R/S MACHINE. Best bang for your buck and most importantly, the sleeves won't sink.

 

i guess im confused, when people say the head of a b16a, which components do they mean?

I was thinking of mating the b16a head (meaning pistons rods etc) onto the b18c short block. But i think i have the terminology incorrect.

yes you do have your terms messed up.
head is the top part of the motor including valve cover, cast head, cams, valvetrain ect.

block is the headgasket and DOWN...(pistons, rods, crank, sleeves, ect)

This won't work. Even with 85mm bores, you will only get about 1740cc from a B16A block with stock 77.4mm stroke. But I digress. If you already have a P72 block and crank, why not save yourself alot of time and headaches and just use stock GSR/ITR rods and pistons? You will have 1.8 liters right off the bat with a better rod ratio to boot. And it will be FAR cheaper AND better than trying to stroke a B16A to 1.8 liters. Hell, for the price of a stroker kit, you can also resleeve your B18C block to 85mm and have a 2020cc motor with a better rod ratio than a 1.8 liter B16A stroker could ever dream of (even if it is only 1.58:1). Or, if you really want a better rod ratio, use a B17A crank in a sleeved B18C for a 1.8 liter motor with a 1.74:1 rod ratio!

Technically, the part of the engine from the headgasket down is referred to as a shortblock. The term 'block' generally refers to a bare block (ie no pistons, rods, crank, etc.).
