How much to boost a 2nzfe engine..

[leinadeb]

Can anyone tell me the maximum boost that a 2nzfe can hold without making any damages to the engine please? Thanks

[thebarber]

has the same compression ratio (10.5:1) as the 1nzfe

i wouldn't go more than 8psi on stock internals

Id agree on the above statement

+1

And it depends on how you drive. If you do a season of racing @ 8psi on a stock motor, you might definitely see some engine damage.

You will have some measure of reduced engine life though, e.g., it's not going to run for 100,000 miles like that, just to be clear.

(but the miles you get will be REALLY fun)

Moved this to the forced induction section. :wink:

It can probably hold 1 or 2 psi more than the 1NZ because it has a slightly shorter stroke... 11.2mm shorter.

:wink: Some one send me a kit and we will find out :drool:

Hi, but what is the better? Turbo or Supercharger for a 1.3l 2NZ-FE Yaris?

Greets.

without getting into the pros/cons of anything other than the end result:

turbo > supercharger

[crolandiz]

And what is aprox the max HP I can get with a turbo on a 1.3 with std internals?

As much HP as 8 psi gives you with your specific build and tune.

what about 1s zfe? how much boost it can hold on stock internals ?

^ I don't think anyone knows this for sure. Do it, then tell the rest of us. :biggrin:

What's the compression ratio on that engine? From that u can give u a gusse

The same as the 1NZ > 10.5:1

I made 180 whp on 8-9 psi on my stock 1.5L 1NZ-FE.

with a little less displacement, you'd get a somewhat lower number, everything else being equal?
