TT VS N/A:Oil Pump & Compression Ratios (8.5:1 vs 10.5:1)

[gpelite]

I would like the TT ppl out there to review my plan here and give me the low down on what problems I will see and compare their notes to what I have heard about each part of the conversion as I listed them seperately to get more response and inspire experts on each issue to respond. Please write as much as you see fit to get all points across. Anything is appreciated and will be added to my compilation on the conversion for future Z owners

Oil PumpThe debated issue of the oil pump, it is proven a TT oil pump will put out around 90psi compared to a 60psi N/A pump. I could replace it yes, but I don't do a ton of messing with the crank, timing belts, I just don't trust myself to mess with those components. Since the pump wraps around the crank, I elect to not touch it. Oil pressure of 60psi, won't kill turbos, but will limit me to running a limited amount of load on the turbos. Which leads me to the hated topic of.....

Compression (Depression )Well when I started working on cars, and bought my Z a few years back I had no clue what turbos were. As I began to cruise I got the gist and researched. I found out the terrible secret that is compression ratios of N/A and Turbo cars. As I mentioned before, I don't want to personally do major work on the engine that has to do with timing components. So I got these pistons, kinda high compression here. 8.5:1 (TT), 10.5:1 (N/A) I wanna run my damn turbos, what boost pressure is safe at a 10.5:1 ratio?? Don't say no boost, your gonna break my heart here ppl lol I've seen N/As take high boost, the lancers can take 12:1 ratios well so why can't the ZX take at least that. Now its flawed logic on the grounds of production technology, engine specs, and intended uses but I think it should work still. Will I spring for pistons, eventually--- but now, No can do. I can't afford a rebuild professionally. Give me your take, this is the biggest issue out of the whole thing... in my opinion. What should I run given my limitations, be honest
