Since the rods are the weakest link in the stock motor, would only upgrading the rods to some forged rods be enough to make a vortech build safe?

Assuming 410ish hp and 350ish torque is there anything else besides the rods that might not like the power increase?

I mean I wouldn't need pistons because I wouldn't be running enough boost to warrant dropping the compression ratio. What about crank or cylinder walls?

 

If you are going to take the time to tear apart your engine, then you might as well go all the way and build it up. Have you checked out the engines at IPP? They are known for their awesome work on 300zx's.

Seriously, if you're already going to be in there, you might as well do the pistons too. I don't see why you wouldn't.

 

It would be very short sighted to pay the labor to pull the engine and disassemble and then reassemble the engine without upgrading more than rods.

Keep in mind that the VQ35 was not designed for FI. No rebuild will be safe. What it would do (if done correctly) is reduce the risk of blowing the engine. And keep in mind that tuning is at least as big a factor as the engine components. A bad tune would blow any rebuilt engine.

 

why not get rid of the junk oil consuming rings while you are in there

 

If you are going to do it, do it right.

 

Rods and Pistons, Head Studs, Main Studs, Cometic Head Gaskets....your good all day the block can handle daily probably 600whp....PM me if you want more insite...

 

Also this web site has block packages. seems to be about the same cost. http://sgpracing-store.stores.yahoo.net/sgpravqmo.html
