Strange question this one, and im not sure anyone will be able to really help with an answer thats definitive, but im sure people on here must have moved engines forwards and backwards before, so I may get lucky with some info.

Basically ive been measuring up the location of where the V8 needs to sit in my engine bay on my calibra.

Engine is 70CM long, of which the back 60CM of it basically has any significant weight.

Where its going to need to sit, I would have 50CM of the engine in front of the centre line of the strut (and only 10cm behind)

IE the centre line of the struts would be roughly inline with the sparkplugs on the back two cylinders.

Normally this engine would be sat approx 20CM further back than that in other cars it goes in.



Now im aware in principle that this movement of the engine forwards is going to give it a tendancy towards understeer.

The engine weight is 190KG

So essentially, The 20cm thats being added onto the front, weighs about 70KG probably.


So effectively what I will have done is the equivalent of fitting a 70KG weight about 40CM in front of the strut top centreline (slightly less far foward relative to the centre line of the wheels of course as there is some caster on the vehicle)




How much is that going to ruin the handling, are we talking 1 second a lap and feeling slightly less willing to turn in, or are we talking totally fucked and being a complete nightmare to drive?


I guess easy way to find out is install a 70KG weight in front of the engine on my sierra and take it out for a drive, but just interested in opinions!
