What are the main differences between the HR and DE motors? I was trying to find a stick where maybe the differences are laid out as I was searching maybe one should be added here.

 

The differences that I know off of the top of my head are a higher redline and extra HP. Not sure what else is different though.

 

DE designed by Renault built by Japanese

HR designed and built by God.

 

^^ Amen

there is a ton of info already discussed on this topic and another thread is just gonna bring the HR nuthuggers out

 

I've owned both and I would never own another DE again after experiencing the difference. The HR is an amazing beautifully engineered engine. Hydrogen free diamond like coatings... and as if to show off how much better this engine is they put the oil dip stick right there in front, where it should be, instead of that stupid side dip stick on the DE

 

I need an HR hugger panda now

Listen we've been over this before,

DE vs. HR = not a 370z

hr is kewl tho. I think it's more torqueyer

 

No wonder my pockets feel so holey

 

Hahahahahahahahahahahaha...

Puns usually make me gag, but that made me chuckle

 

hahahahahaha... this guy

 

Almost spit out my Fruit Loops.

 

Here is a question, has anyone converted the HR heads to the DE block? To get the continous valve timing on the exhaust side?

Can we use the vq37 pistons/crank/rods in the DE motor anyone done that conversion. Maybe save money vs doing the stroker kits that are 5000+

 

Why not just get the stroker kits and skip just a little bit of the headaches with mixing and matching and getting something to control the cam timing at every rpm.

But if you think you are willing to put the time, money, and effort, i say GO FOR IT. To answer your question,I havent heard of anyone doing this.
Maybe someone else can elaborate....

 

Arent all the HR's starting to go kaboom now too? It seems every single week I hear about another one. I know 2 locally that have threw rods making 450+.

 

Welcome to 2007.

 

Well I'm looking more at the NA side, not pushing 450whp+ on a stock block. Even an HR block.

Yeah I was just wondering if anyone had done a hybrid type build or if it has been tried.

 

I'm running a standalone right now, only issue would be getting the HR heads on the DE block however that would work heh. Have the capability to tune the cam timing on both ends right now.
