2.0 crank in a 1.8

[Madmax914]

I'm rebuilding my 1.8 for street use only. I'd like to wake-up the hidden potential of this little motor. I have an opportunity to purchase an 2.0 stock crank and H-beam rods. Will this set-up work in my 1.8 case and if so what clearance problems will I face?

[Bruce 914]

It will fit. No clearance problems.

I have that same complete setup for sale with euro 94mm pistons for sale here...

You will also need 2.0 pistons and cylinders, the 1.8 pistons won't work.

They'll either stick out of the cylinders at TDC, or they'll give you 300 thousandths of deck height, and about a 2:1 compression ratio.

You can turn 1.8 cylinders into 2.0 cylinders by having them bored. Better is to have them jigged up in a torque plate and honed out from 93mm to 94mm. Alternately, you can have them honed to 96mm, and get the 96mm pistons intended for the 2.0 crank and rods. That'll make a 2056cc motor, which is usually a nice strong one.

Thank you everyone for all your help, sounds like I really can't go wrong by buying it.
