Can you get to 400 without turbo or super-charger

Skaterbasist · 02-23-2009, 02:51 PM

For those who have been around the VQ community, my guess will be no. And if it ever was possible, get ready to spend over 10k in a full NA engine build. Not worth it...

Ditch the 370Z and get the 380RS-C.

VQ38HR with 395 HP and 310 lb-ft torque, and it uses Motec engine management. $250k... not street legal, of course.

You know how we have the '08 NISMO Z with the nice suspension upgrades and funky body kit? In Japan, it's the 380RS. It is everything out NISMO Z is, but there's a 3.8L HR engine in it pushing 350 PS. There is a competition version that is gutted out with a race built version of the 3.8L HR tuned and controlled with Motec gear.

Google... and drool.

Um it's called the 380RS but it still has the 3.5L VQ35HR. Says so in the first video on google and also on the Nissan spec sheet.

I haven't read all five pages but Cosworth has developed a 400 horsepower N/A motor...It can be had for around 30K. Not trying to be sarcastic or anything. It can be done and some people work very hard to stick N/A and be the most power N/A...But it's not cheap.

$14K gets you an LS7... So for half the loot, you can drop in a 505HP 500Lbs/Tq motor.

Much cheaper and still extremely reliable.

If you're going to go N/A and spend that much money, might as well do a motor swap.

Agreed...However then you're talking about a new transmission and driveline that will work with the LS setup. So you'r back up to over 20 by the time everything's installed and operating. At least in my mind...I could be wrong. I think you're right about doing a motor swap though. There are conversion kits out now for the Titan motor fitting into the Z's. I'd bet you could easily achieve over 400 HP N/A and fit within a 15K budget.

LSx swap is always a good option.

can someone please explain what is this NA and FI that everyone is talking about?

Thanks in advance,

FI means Forced Induction, which means adding a Supercharger or Turbocharger setup to compress the intake air. Generally a pretty expensive mod.

NA means Naturally Aspirated, which is the opposite. The engine is just drawing intake air with its own suction, like our stock 370Zs do.

Meh. It's a pretty much maxed out N/A motor, but makes a good twin turbo motor.
