That was a discrace! I wouldve put a Titan motor in there instead.

In order to make 350rwhp, it would require a stroker, heads, cams and a capable intake manifold(cosworth) for higher rpm capabilites. It would be cheaper to go with a supercharger, if thats all your looking for

 

lol... I believe it's been done


I was just wondering if anyone has done all that, I've searched but haven't seen any mid to high whp builds. Most people go turbo or supercharger and I know all about all that, I was just wondering the cost versus the power for na and if na is worth it.

 

Hope you not


worth or not, you will never get that answer untill you try.

And Here is my answer for your Question: Yes it is possible.

 

I guess I'll have to do it then. I know i've seen the pmu 350z with 350ps(245hp) but it has no2 and idk if that' whp...
I was thinking of doing a tomei build (272 cams, valve springs, rods, gaskets, studs) If i did go na, seems like a fun project to dive into

 

No offense but from the questions your asking I honestly am going to advise you to save yourself the trouble and just slap a turbo on your car and call it a day.

Building an NA motor is a long and tedious project. Especially when you are trying to accomplish what so far what only race teams have accomplished since the inception of this car (as far as I know).

I can promise you that you could do a complete build off the entire Tomei VQ35 parts catalog and you will not reach anywhere remotely within 350rwhp.

 

^I agree with the first part.

 

I haven't seen anyone on these forums get close to 350 rwhp with an NA motor. Adam is the NA record holder with 320 horsepower. His Z is well thought out and still fun to drive, so it's not just a dyno queen going for the NA record.

Jeremy at the Performance Factory build an NA VQ35 that dyno'd at 305 rwhp. He lost interest in it and went turbo later on, but that was an interesting engine. There was still a lot of horsepower left to be gained in it.

I'm just getting started on an NA build at the Performance Factory that will extend some of the technology Jeremy discovered while building his NA motor. Although I have high hopes for this engine, I'm not expecting it to produce 350 rwhp. I am looking forward to the day I can zing it through the gears with my 4.08 rear end, though!

There is a small group of dedicated normally aspirated VQ35 fans here on my350z. We like them because they are more responsive, more fun to drive, and somewhat unique in the Z and G world. You'll have to listen to the majority of my350z FI people parrot that FI is the only way to go, but NA engines rock! Good luck with yours if you decide to build one.

 

I'm also one of those NA enthusiasts. Getting ready for my build too. I'll be quite happy with NA 300+whp and a set of gears... And more importantly, knowing I have a fairly reliable setup. :-)

Listening to the FI guys brag about getting 30k miles out of their motors before they go BOOM, or how they're always fixing this or that on a daily basis before they go BOOM is unacceptable to me...

 

300+ rwhp AND 3.9/4.0 gears? no thank you.

 

Why not?

 

with the stock 3.5 gears at 260-270 it's fun enough. I don't see the need to sacrifice taller gearing personally

but give me a ride, convince me

 

Erin, to be honest the reliability of any motor goes down significantly once you start highly modifying it. It something you have to tell yourself before you start dumping money into any project. That goes for FI, SC, NO2 or NA.

 

Yeah, true. That's why I backed away from a NA stroker build... Well, that and cost. BTW How is your stroker project coming?

 

To each his own I suppose.

All I know is Adam's car with the redline set at 8400rpms and the 320rwhp he is putting down is a blast to drive with the 3.9s. If your thinking it suffers on the top end, trust me it doesn't. It has more than enough room to rev out.

 

God I wish I could have taken a ride

It was just nice enough seeing one of my favorite Zs of all time. So that means I'm getting a ride in both of ya'lls Zs next year

 

I'll have it wrapped up by this summer. We've been really busy at the shop and our other projects that this was being neglected. Not to mention our engine builder had his first born. It's back to being a top priority now though.

Although I am interested to see what you've got cooking though with your build.

 

Just make sure you leave that "grape drank" outside of the vehicles before you enter them. Come to think of it you might be one of few people I know who will fit in my passenger seat comfortably now that I have the Kirk roll bar installed.

 

I'd be interested to see Chris as a passenger is that's the case

 

oh new avator lol

 

Good luck,
