At home in the states I had a full garage. Working on engines was a hobby. Since being in Colombia (6 Years) I really havent been able to get my hands dirty lol.
These days I am getting an itch, And I need to work on my engine.
The idea I have is to fully tune my 180 to get as close to the 200 as I can meaning-
The Apache 200 is 197.75 cm3 Apache 180- 177.4cm3
Bore- 66mm 62.5
My question???? How far can I bore the 180 to get as close to or match the 200 ?? Is possible?
Apache 200 compression- 97.0.5:1 Apache 180- 9.5, 0.5:1
Also- change piston to increase compression to 11:1 Is this ok? will the block handle it?
Upgrade carburetor The 200 has a Keihin CV I need to see if the apertures are the same size to switch out or just by one if there are recommendations I am happy to listen.
the 200 is 4 valve, the 180 2 valve. I Need to see what I can do to upgrade to 4 valve , better cam, valves. port and polish valves and intake\exhaust.
Install Oil cooler for added cooling
Install tunable exhuast
Does any of this make sense?
Opinions matter Thank you all for your time. I hope my forum manners are ok and sorry in advance if i miss posted in the wrong area.
