I have a D16Z6 bottom end with a D16Y5 (vtec-e) head on it. Running a .48/.60 T3, uberdata, etc.

I'm wondering what the rev limit is now? Hoping I can rev a little higher than the stock Z6 rev limit (6400 I think?) because of the Y5's roller rockers.

What do you think?

 

I wouldnt go any higher than the z6's stock redline. I also dont think that head is made to rev even as high as a z6, but im not sure.

 

why would you put the y5 head on and not the y8, ever your stock z6 head would be better?????? just curious, but all in all to answer the question, i would stay under 7200

 

ON NO ITS ORGAZMO!!!!!


stock z6 redline is 7200, i wouldnt push it much higher than that

 

Yea I'm a jizz machine.

Thanks guys, 7200 it is.

And the reason I'm not using a different head is because this is the one that came with the motor.

I get 30+ mpg CITY while raping it all day long

50+ mpg highway
