Great work Charlie. Thanks for all the good posts.

Does 20v mean it is a 20 valve engine? I think not but???

i wish. we all wish. I **** the only differnces are the exhaust manifold and the computer

No, 20V does not mean 5 valves per cylinder. The differences are the intake and exhaust configurations and perhaps the ECU mapping.

What I want to know is will that nice looking valve cover fit on my motor. I want one :)

man that looks clean, i cant even see any wires. maybe by the time i can afford a VE those things will be available at a decent price. I remember hearing somewhere that it was throttle by wire, does anyone know if there is truth to that?

Are you guys sure thats all they changed? The 97-99 20ve makes its peak hp at 7k while this one makes it @ 7200rpm. Im thinking they also changed the cam profile.

Also it comes with a 6-speed tranny similar to that of the sentra spec v and maxima. Way cool and its stronger than ours. But the motor is Throttle By Wire. Im not really sure what you would have to change to be able to install the motor.

I know I asked this stupid question but it always bothered me that they call it the 20V. I thought that all they changed was the exhaust mainifold and the tuning. I know on my car when I changed just the exhaust (not the header) I gained 400rpm of power before the peak (ie: peak went from 6800 to 7200 rpm). I could see Nissan putting a factory header/exhaust and gaining 12 hp easily. Just depends what they had it on to begin with (ie how good or bad it was).

There was a picture of the motor on Nissan's web site with the exhaust manifold exposed and it was clear they changed it to a tubular design. The web page mentioned the increase in power came from changes to the intake and exhaust manifolds but made no mention of changes to the cams or ECU.

All I can say is that is a beautiful engine... And it would look great in my engine bay!

So who is going to be the first to try extrude honing thier intake manifold OR a Bored TB? B.T.W., Mike Kojima asked me were to get a SR20VE and I sent him to Andreas. Maybe Mike will do some more development work on the VE for us. One can always hope. In case your wondering why I don't... It's my daily driver and I cant afford to have it down for very much time. Maybe in the future. A bored TB doesn't require a change in ECU if I remeber right. Is that correct?

I thought CNibbana was going to do this.

That's what I was told by JWT. I was under the impression they only wanted to know what MAF you had and what type of engine you were running (SR20DE, SR20DE 11:1 comp, SR20VE). I'm not even sure they cared which injectors you were running.

Steve

They Definitely need to know what injectors you're running. Throttle body size is not important. BTW, what is the stock TB size on an SR20VE?
I think CNibbana was goingto extrude hone his exhaust manifold, not the IM

Same as a DE. I used my DE TB. They matched up to my eye.

Second generation SR20VE has redesigned intake manifold, and equal leangth stainless steel exhaust manifold. Nissan Japan's homepage says, they enlarged the header pipe diameter too.

This new VE is also the drive by wire (throttle by wire) engine just like QRs. So throttle body from this engine probablly won't work on older VE or DE engines.

EDIT: I mentioned about variable capacity exhaust manifold on this post earlier, but It was my misunderstanding. I'll post more info when I find out about this.

So unless a typical SR20 throtle body will bolt on in place of the drive-by-wire throttle body, there is practically no way this motor would work on our cars. In order for it to work, the original SR20VE 20V computer would have to be sourced, or JWT would have to put in some major R&D, which i dont see happening because they would hardly move any units.
I guess it's a possiblity to bolt the whole intake manifold from the typical SR20VE onto the SR20VE 20V motor, but that would pretty much be pointless as just the IM/TB would be difficult or impossible to find

That intake manifold looks very similar in most places. Even the place were it separates into two pieces looks the same. They just took a lot of stuff off of it. It is missing both the idle control solenoids. The throttle body is in the same place and even at the same angle as every VE that I have seen. An easy way to find you if you could switch TB would be to see which TB gasket that car uses and compare the number with the older VE. You would need to weld on some brackets for the throttle cables.

It was the Variable Intake system just like the one on QR25 or VQ35 motor. Nissan miswritten one of the paragraph and it says it's the variable exhaust manifold. Because one paragraph says it's the variable capacity exhaust manifold and other one says it's the variable intake system.

Sweet.
