I would also keep in mind reliability , more power more issues..

:iagree: Still contemplating which route to take. Thank for your thoughts on this Cosmo

Ok guys is it really necessary to replace the OEM parts i mention on the first page if i build the motor with just 26,200 miles on it? Obviously that question would be better answer by checking the engine first like The Dreamer mention but i still think is pointless, just a thought.

You're adding boost to a NA car. Just be careful and keep boost low if you're that worried.

If you are just going to run around with 500rwhp, than you have a better chance at reliability with the stock engine than you do a built one. You also have a far, far greater chance of being able to enjoy your car anytime soon if you stick with the stock engine.

Building the engine in a 370z is adding too much potential for human error or mistakes to justify attempting it for power levels that have been proven reliable in well tuned and well put together cars with the stock engine. We have seen very few engine failures in this community and I am not certain if we have even seen one that was strictly from "too much power".

Having been in the VQ Z scene since it started, I can say that it is not uncommon for the heavier projects to sort of fade away into the darkness. Shops fly past deadlines, engine assembly problems haunt and the car is in the shop more than its on the road, etc etc etc. The engine and the electronics in these cars are more complex than most shops are used to, and the information is few and far between.

The only well paved path with these cars is a 450-600rwhp stock engine setup. Anything past there, and you are risking serious trouble unless you are a highly qualified DIY'er or have the utmost confidence in your shop/tuner.

Thanks Charles for the good info. I'll do that just install the kit,get a good tune and have fun. Do like your fuel system kit, been thinking of adding it to my build.

completely agree with phunk. building engines requires someone highly reliable..which usually ends up being harder than it sounds

Fast Intentions should build engines for customers..:tup:

That should be standard! :tup:

Agree +1 here too!!

Ok just a simple question, where the heck can i get ARP main studs from a vendor? I google it and all i get are the L19 head studs but no main studs. I only found them on GTM website which sucks for obvious reasons :shakes head:

Here you go. I use these guys for lots of stuff.

ARP 202-4701 Head Bolt / Stud Kit, Nissan 09+ 370Z VQ37VHR Z34 - Nissan performance parts

And +1 on stock block reliability and frustration avoidance. I have a friend who has a G that has been a statue in his garage for 3 years due to the built motor plan..lol.. Poor bastard.

However that same guy is putting a monster turbo on the BP kit. Should be interesting...if It ever sees pavement again. :ugh2:

There's another G lined up to follow me with a BP kit?

Thanks Topgun. :tup: Now i can order those with the L19 head studs

Lol. Yup! More studs than you can handle. Whoops. Not sure man.

Yeah. But its a 35 and he's going with a 7275. He is going for 900+ at the wheels.
