the important thing though is that the 4g63 is most of its potentia lhas already beeen tapped
the VQ is a relatively new motor, and theres alot of potential left
when honda switched to the k series alot of people were mad but now just over a year and a half. alot of the potential is starting to show
nissan makes great motors and i expect great things from the vq

I'm trying not to sound like a dick, but please do some research before you post anything on turbocharged cars.

BTW, the EVO8 has already run 12's. Go here
You're right I've got it backwards. I just assumed because it's turbo the compression is higher.

But are you saying it's not likely a 350Z with turbo would be a match?

There's potential in the Z (I don't know how much because I'm new to the VQ engine), but the 4G63 in the EVO has been around for over a decade. That being said, there's over 10 years of experience with these engines and it is why the engine is still being used on race cars (running 8's). There are many street DSMs running 12's and 11's in street trim as well.

Another thing you don't know is that most turbocharged engines have lower compression because they run a factory turbo. That's why they can run higher boost levels (with proper fuel support).

The EVO's compression is 8.8:1, the Z is 10.3:1. Yes you can add turbos to the Z, but reliability will be sacrificed. So you got it backwards, the EVO is the one that can run a turbo AND NOS, and no it doesn't have to have a built motor.

So, if the 350z came with a factory turbo, what would you say then? Wouldn't it be spanking the EVO?

we need to turbocharged the 350Z if we are going to challenge any Evo, because most of them won't be stock for long. As much as I love my Z, DSMs rule the streets and Supras rule the highway.


Sad thing is, we can barely beat a FWD Neon SRT. So back to reality people!



sh*t.. here comes the flames.

A turbo charged 350z with a good amount of boost would beat a stock EVO. They do a 1/4 mile in 13.8 or so. Now after they add a few bolt ons, i belive the evo would be a bit faster...in hat one link that was posted they had the evo do a 1/4 mile in 12.59...

A 400hp 350z would prolly do the 1/4 mile in 12.5-12.6 right? All the calculators i have checked out said that's about right. But then again, they're calculators

Bottome line:
EVO8 is already turbocharged. They will be made quicker/faster very soon.

To turbocharge the Z will be expensive and your average Joe (like myself) will not be making them as fast as we want anytime soon. Intake and exhaust on the Z won't cut it.

Intake, exhaust, boost controller, and race gas will make the EVO plenty fast.

I'm not beating down our Z's, I'm just being realistic. I love my Z and will do whatever I can afford to do to make it fast.

I know the experienced guys with Supras and DSMs that are on this board know what I mean.

I know what you mean. You're just trying to be realistic. We love our cars for what they are.

I know what you mean too. All I was saying is that a Z with a turbo (although costly) would kick a stock evo's ***. That was my only point. I don't care about price, that's not what I was talking about. SO, turbo for turbo, the z would kick its ***. Anyone can throw a turbo in a 4 cylinder nowadays and make it haul ***. Big deal.

Now if the Z had a stock turbo built in, I would assume it would have a ton more modability also right? But since a turbo is not built in, we won't be able to squeeze too much more out because our internals are not designed specifically for a turbo. Is my logic correct?

dont forget the power of all motor
its a 3.5litre motor thats alot of room for power also theres the rumored crate motor
i think we can hang all motor at least once the nismo ecus out

It's not rumored, they really sell it. Good point though, the crate motor is based on the same engine.

First off, 19 psi from one turbo is not necessarily the same amount of boost as 19 psi from another one. A larger aftermarket turbo will probably increase boost by a good bit and can be bought for around $1500 b/c they dont need a turbo KIT like us N/A guys need.

Also, 19 psi is PEAK boost, from the dynos that I have seen, it seems like the boost is dropped to around 13-15 psi at higher rpms as a buffer for the motor. With a boost controller, you could probably boost at least a few more psi, which should result in 20+ hp right off the bat.

Also, the VQ block is not a new block. The VQ30 has been used in Maximas for years! I think the VQ is a good motor, BUT it's not by any means amazing. There are three ways to make a car go fast (from a engine standpoint): 1. high revs 2. lots of displacement 3. forced induction. Unfortunately, the VQ doesnt really accel at the 1st two and it doesnt have the third.

Finally, I think the "if the 350z had a turbo" arguement is rediculous. 1st, if it did have a turbo stock, then it would cost a lot more, putting it out of the price range. Also, that's like me saying that if I had 3.5L in my type R and made the same 108.5 hp per liter, I would whoop up on y'all. The POINT IS I DONT HAVE 3.5L OF DISPLACEMENT TO WORK WITH AND YOU DONT HAVE A TURBO. 2nd, if you go aftermarket for a turbo, then yeah you'll be running 12's maybe, but with around $40,000 invested in it! Imagine $10,000 spent on a EVO VIII, that car would run 11's easily.

However, the EVO guys pay for their performance by sacraficing comfort, looks and class. I mean honestly, if performance was EVERYTHING, I could get a 92 Civic Hatchback CX and with $18,000 including the price of the car, I would run 11's no problem, NATURALLY ASPIRATED and pull 1g on the skidpad (B20 VTEC motor with Toda Spec A cams with a OBD1 ECU with Hondata, Ziel B6 coilovers, chassis stiffening, stabilizer bars, ITR upper control arms and a ITR steering rack, intake, headers, exhaust, Volk TE-37's 15 in). But it isnt everything, so be contented that the 350z is one cool car.

Umm, out the door the dealers are asking 40k. So our cars are cheaper and a little slower, but nicer. SO, is the 350z with a turbo arguemnt that ridiculous? Sorry, you're wrong. So if I put a turbo in my car, it's equivalent in price to an evo, AND it's faster.

He said a kit to run 11s or 12's. So if you already a higher up in price model, he definately low-balled the number. This is definately a rediculous arguement........unfortunately

We have to face the fact that we bought a NA car. You can't love you car for what it's not; love it for what it is.

Wow, you don't understand. Yes if 10k was put into an EVO it would be really fast. What you are not getting is the fact that the EVO costs about 6-8K more than the Z(currently). I heard someone on here say "40k out the door" for the EVO. So with 8k in the Z, it would be price equivalent to the EVO which comes stock with a turbo. do you understand?

I see what you are saying. However, dont count on EVOs to hold that price for very long. I'm predicting it'll fall substantially.

Right, but the stock EVO costs a substantial amount more. So we're already comparing two cars that are in different price ranges. So it's like comapring a 350z to an RSX-S right? So I guess why bother at all? right?
