Alot of reading, listening and learning to finding the most effective turbo for my little 1.6 idi diesel pickup. I think I've narrowed it down to several. I am open to other turbo selections also. I have questions on the 4 listed turbos in the title. (k03, k14, GT15). I'm hoping to get real world experience and driving characteristics from actual on the road turbo charged mk1 or similar vehicles

Manifolds used will probably be a BAE turbo intake and exhaust (3 bolt exhaust to turbo flange)

I have a 1983 VW PICKUP with 1.6 DIESEL and 5 speed. The motor is a fresh rebuilt that's balanced and 1 size overbored. New Giles superpump and injectors. 3" exhaust.

I would like to achieve better bottom to mid range Power. Good drivable non race type. I don't have fantasies about an unrealistic hp increase, but think 80 to 100 simple HP (non TDI) is achievable.

What are your thoughts and experiences on turbo type, A/R, trim etc to match the above criteria?

i think you will get better results on TDI club. ko4 sounds giant for a 1.6 liter.

Update
Picked up a k14 and exhaust manifold. On the way right now to be rebuilt, exhaust polish and ceramic coating. I'll be using the BAE intake The BAE turbo and exhaust went to a serious collector

Got the k14 td downpipe on its way

The oil to turbo feed hard line

TD 3 port oil filter stand (realized it is mk3 and has a different bolt/passage pattern than mk1/2). Below shows the mk2(?) 3 port that id love to find. Nur you can see the oil passage/not pattern differences
