I need some assistance please...

I am sending my block out to RS Machines for a resleeving, honing and reassembly. I am re-using my Crower rods and installing new Arias pistons. My goal is for 300whp on a EMS system. It's definatly an acheivable goal but the catch is I'd like to have a final cr ratio of 10:1. The head will remain stock. Is 300whp at 10:1cr on an EMS system safe? This is to remain as a street car only with a T3/TO4E turbo system for the power. I hope to be able to run around 10-12psi to acheive the 300whp. Is this safe?

Thanks!

 

youll be prefectly fine. just use a conservative tune on pump gas(a little extra fuel and conservative timing). race gas is a different story

 

Thanks. One important factor I forgot to mention is that it is being bored to 83mm as well. Trying to also achieve as close to 2.0 liter as possible. Does that make a difference?

 

I'd advise you to do some more research on sleeving before you have it done.

That CR is as safe as the tune.
