Hi Guys .. I'm being told that it is better to rebuild a 1.8 to get more torque from the engine then rebuilding the 1.7 .. and even the 2.0 casing .. would love a 2.0 but they are getting harder to find .. Is this TRUE ... If I should look for a 1.8 then spend too much $$$ in my 1.7 .. What's your thoughts ... ???

I'm not sure about the 1.7 or 1.8 heads not being used in any upgraded engine... I would think they would be OK for mild upgrades, particularly the 1.8 heads.
The 1.7 heads have 100mm "registers"--where the top of the cylinder fits into the head. The 1.8 and 2.0 heads have 104mm (105?) registers. There are 96mm cylinders that fit into the 1.7 heads, but the tops will be less than 2mm thick. Not a great idea for longevity. Far better to use the 96mm cylinders that are intended for 1.8 or 2.0 heads. You get a 1911cc motor when you use the 66mm stroke with 96mm P&Cs. It's a nice modest upgrade... --DD |
