Ok I am going to rebuild my mates 16V engine in his Calibra....
Just want to get it up to good spec and a strong engine...
go for a 2mm overbore on bottom end
New pistons and rings
Re-Ground crank and main bearings
Bottom end balanced and lightened
Fast Road Cams
Gas Flowed Head and bigger valves
Chip \ Filter \ Exhaust
From that lot I reckon a safe sturdy 180bhp....now he wants to add throttle bodies at a later date to increase power to over 200bhp which I know you cannot do with the standard SFi therefore it makes sense to take this into consideration whilst the engine is in bits.....
What additional work would engine need to cope with the throttle bodies....?
