Hi there, this is my first post over here!
I have an Audi 80 B3 with 1.9 1Y engine for a couple of years. It is a nice and simple car for cheap commuting and trailer pulling. Since it felt really sluggish compared to my gasser Toyota, I installed k14 turbocharger from AAZ engine and turned IP up a bit. It was a great improvement, but I want some more.

Currently I´m running stock 1Y pump, which seems to be same as eco-pump (8mm plunger, 2,55mm lift camdisk, no LDA). I´ve bought an AAZ IP which turned out to be a bit leaking. So now I´m resealing it. I have some different bits and pieces lying in the garage. Since I´m already opening that pump why not mix and match these pieces for better performance.
My goal is 120-ish hp without affecting fuel economy. Current fuel consumption is about ~6,5L/100km (~40 US mpg)
I have:
1,6D N/A pump
1Y pump
older type AAZ pump with timing solenoid
1,6 TD pump casing with LDA
Toyota Carina E TD pump
Toyota IP has 10mm plunger. On my power level, would it have any benefit over stock 9mm? I mean like less smoke and EGT?
1,6 TD pump top seems to have better LDA, so i'm using that instead of AAZ one.
I'd like to get rid of that AAZ timing solenoid and replace it with 1,6D timing assembly. 1,6 pumps doesn´t have load dependant start of delivery. Should I use LDSD or not? Does it has any positive effect on power and efficiency or is it just for noise/NOx reduction?
I've researched for a while but this is still my first "frankenpump" so I look forward to any advice or suggestions.
