IntrAphasE Posted February 27, 2011 Report Share Posted February 27, 2011 right guys sorry for all the questions but would anyone happen to know the compression ratio of the aee engines so i can work out the depth of the decomp plate i need for my aee turbo build Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted February 27, 2011 Report Share Posted February 27, 2011 AEE is an dog old 74bhp 1.6 8v isnt it? its a 9.8:1 CR, the engine was superseded by the AEH (10.3:1) and then the AVU (10.5:1) which produced 99 and 101bhp.I cant see how your going to work out the plate based on that though, you need to add in to the calculation the bore size, combustion chamber volume, deck height and stroke to get it right.Should be good for what 140bhp with a turbo? Surely its a better idea to go for the 16v engine? or the later engines?Will be good to see what comes of it though, keep us posted.John Quote Link to comment Share on other sites More sharing options...
IntrAphasE Posted February 27, 2011 Author Report Share Posted February 27, 2011 thanks john yeah the AEE is the old dog 1.6 8v yeah the guy who is producing the the decomp plate wanted to know the original compression ratio and also what ratio i am aiming for looking at running 1.5-2 bar of boost from a garret t28 charger so any advice on what compression to aim for will be appreciated im a bit of a old dog when it comes to engines i have a 175bhp throttlebodied 8v track car so keeping the arosa 8v is my style and why the AEE it was cheap and needed to be dropped in a hurry as the 1.4 8v died Quote Link to comment Share on other sites More sharing options...

Not going to happen. Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted February 27, 2011 Report Share Posted February 27, 2011 From what ive read, the conrods are referred to as twiglets? And G40 pistons dont fit due to the gudgeon pin being the wrong diameter. Id think you'd need a CR of about 8-8.5 on standard internals. I cant remember what the G40 had but that is renowned for shi*ting standard pistons when boost is turned up and driven hard. Quote Link to comment Share on other sites More sharing options...
