Tuning Turbo tunability

[ShaunCo]

Hi guys, in terms of the coupe turbo engines, 16vt and 20vt, which one is more tunable?

im looking into the conversion for my bravo but not too sure which one will be more tunable and also be reliable when i do start to increase power?

any pointers?

im swaying towards the 16vt as iv heard u can, with alot of work and money, put a 4x4 drive system on it

Both are very "tuneable"
Both can have a 4wd box bolted on

16VT has a long history of motorsport success and high horsepower reliability. 20VT will be easier to get power from due to more cylinders and more valve area

how can the 20vt have a 4wd box? what car from?
