I am in need of rebuilding my Motor and I was looking at the Z! motorsports level 2 kit. Seems to be a very well put together kit and well priced. I am NOT going to be boosting this car. I have another car for that (<3 2jz). Soo I was looking at the high comp set up with the .020 over. What i need to know is will i need a retune befor driving this car? I am assuming to actually use the setups capibillities I will need to tune. I will have my full header back and a full intake plenium set up. Mrev2-kinetix up, k&N drop in. We are assuming that the stock ECU will compensate for the higher compression but I need to make sure im correct. Any help woould be great.

thanks!

 

it will absolutely require a professional tune (and no, we are not the same Z1, so I have no idea on the capabilities of that engine)

 

Thanks^, im sure they will chime in.

 

I'm curious as well. What would be the difference staying n/a vs stage 1 and stage 2? How much can be gained either way?
