Your on h beams and your shooting for 650awhp? That's going to turn out in a disaster. I would invest in some good rods and dual springs before you worry about installing a big turbo with a motor that can't handle the power.

 

i think the rods will be fine...have made over 800 with them in hondas...

 

Honda's also dont have torque!

 

H beams will be fine, i have no idea what you guys are talking about. Its Torque that folds rods by the way...not HP per say.

 

Manley h beam is one of the cheapest h beam rods on the market. H beams will not hold the power and torque he wants to make. Plain and simple.

 

Have you ever witnessed an H beam rod break?

 

Manley underrate their rods. You'll be fine, I wouldn't exceed 500wtq though(to be safe). Horsepower, you'll be ok.
