2e 8v to 16v swap

hi i have a mk1 2l 8v code 2e i also have a brand new 16v head dizzy 4 branch and leads i was going to put this on my 18 gti dx but was told it was a waste of time because the compression is to low will this be the same case for the 2l 8v i am running motor bike carbs so no injection and i have got the 16v ecu if needed many thanks for any help lee

 

yes all 8v blocks, when mated with a 16v head give low compression, and damaged valves

 

You need a 16v bottom end. You can convert an 8v one over, but it would take money and lots of time.

If you have a brand new 16v head, I'm sure that could easily be sold to help fund an engine.

 

can i just replace the 8v pistons with 16 v pistons many thanks

 

No... if it was that easy we'd have said so.

You also need (from memory, so probably not 100%) to change the oil pump, intermediate shaft(?), cambelt(3 off) and other belt pulleys, block off the dizzy hole, and probably more.
