Type 4 - 1800 to 2000 conversion

Asking a lot of questions lately - I'll stop soon!

I have an AP code engine I was looking to convert to a 2 Litre - I have a set of CJ B + P, I believe the stroke is the same on both motors - is there anything else I've missed that means incompatibility? Heads etc the same?

 

you will need crank rods and b+p's from a 2.0l. Heads will be ok.

 

bugger - thought stroke was the same with both

 

nope.... 1800 is 66mm stroke, 2l is 71mm

And as masterjedi has said, you'll need the 2l rods too

 

OK - a set of con rods isnt the end of the world - looks like a full strip down though!

 

To bring this back from the dead.... I'm just about to get round to sorting this out over Christmas and Jan period...

Now, to do a "proper" 2l conversion I need Barrels, Pistons, Rod and Crank also?

But I can do a 1911cc conversion by keeping the standard 1800 bottom end and substituting 2l b+ps, is this correct?

I'm not after BHPs, so if it's not going to happen without big bucks I'll keep it at 1800 but as I have the pots already I would like to chuck them in!!

 

no, you need 96mm B&Ps for an 1800 to convert it to 1911cc

both the 1800 and 2l use 94mm barrels... the diffence between the 2 is crank stroke, rod length, and the crown height in relation to the wrist pin on the piston...

 

Righto - I'm with it now - thanks once again Paul

 

No problem dude
