My S1 elise has had a VVC 160 trophy engine put in to it by the previous owner a company called VTR did the transplant for him.
Now i've been a little bit confused as to whether it is a EU2 143BHP engine or and EU3/Trophy engine.
it has come slightly conflicting parts on it.
coil packs in front of the engine.
52mm throttle body
160 pistons can see the 160 marking on the crown.
now i'm use sure which ECU it is running as i'm struggling to find out ECU numbers.
now if it has an EU2 ecu attached to it would this cause any running issues?
as the car feels somewhat boggy/hesitant low down in the rev ranges (sub 3k rpm)
unlinked issue, i have a top end rattle which seems to disappear when high up the rev range, could this be a fault VVC mech?
