Subject: 1.6L head on a 1.8L block

Date: 	Sun, 1 Feb 1998 22:18:11 +0000



Hi all,



I am currently running a B6ZE (1.6L) engine with FM ECU and turbo. I

envied ( jealous, actually) Shiv's 300 HP figure. I started to think

that I am approaching a declining efficiency if I am still trying to

improve my 1.6L when there's a solid example of a longer stroke can do.



I have access to several BPZE (1.8L) engine block and was wondering if I

can perfectly mount the B6 head on the BP block. This way I can have a

1.8L engine and still keep my FM ECU and other mod. Is this a direct

swap? What other things should I do to my engine while it dissemble

beside the normal overhaul. How much will port and polish help? Shot

peen rod?



I would greatly appreciate any help I can get. I am deciding to go with

the 1.8L or just put in the 13B-REW that I have sitting in my

possession. I would rather keep the piston engine but if I couldn't get

any more out of my existing engine then?



TIA
