More Turbo Theory: Will a 2.0 spool signifigantly faster than a 1.8 block?
All things being equal, will the added displacement of boring a block out to 2.0 Liters offset the drop in compression. How much sooner would boost come (in rpms) as opposed to a comparable 1.8L block?
If its not signigant i suppose I'll be like everyone else and run 1.8

it will spool faster, how much though is dependant upon many things...

Understood, by negating all the variables from my question, i was hoping to get a simple yes/no/1krpm sooner type answer. Just wondering if its worth the trouble.

it will make more torque, but also significantly up the fuel requirements as well.

And my final thought: Given that I have roughly a ten percent gain in displacement, that should equate to a similar increase in exhaust gases? Thus making the turbo spool a bit faster? I knew i should have taken thermodynamics

Re: More Turbo Theory: Will a 2.0 spool signifigantly faster than a 1.8 block? (Brian_92GSR)
Been wondering about this myself.
Can anyone recomend for or against doing this? What are the pros and cons? I was considering the same thing. How much trouble am I looking at down the road? Bigger injectors? Fuel Pump upgrade a must? any trouble dyno tuning ? If the buildup will be for a daily driver? Also what sorta costs are involved in this?
Thanks,
Noel
