Dammit! I get my mind set on a DET swap, then I hear about the SR20VE and the VVL. "Wow," I think. "VTEC for Nissans, great!" So I start researching that, only to find out that those are two different things, plus that the VE was a stepping stone for the QR series.
Now I'm reading that the QR series is all torque and no ponies (a stroker) and I'm not sure what technology it has in it (VVL or VE), and at 10.5:1 for the 2.5 liter it's not good for much of anything (turbo). It's now half a chevy engine.

Now I'm left wondering:
1. What are the specs for the 2.0 QR engine? Will it be more square (bore x stroke)?
2. Even though the VE engine is a building block, will it have more aftermarket uses and products? Can I bolt a VE head onto an SR20DE bottom end?
3. Would I be better off spending my theoretical (as of now) $2500 on a DET or FMAX system?
4. And, does Diet Dr. Pepper really taste more like regular Dr. Pepper?

Entertaining any thoughts,
ryan

The QR20DD puts out 150/150 on paper. I read it on some Nissan site, I think the one showcasing the Bluebird Sylphy. I'm not sure how much the QR20DE will put out. There were some rumors saying the US would get a QR20DE that put out 165/160 or something like that. As for the VE head it should be possible. I think Mike Kojima confirmed that you could do it but you would run into the problems that the LSR Honduh motors run into with oil and all that. Vernon is entertaining the idea too last time I talked to him... which was a long time ago... if he could only get his hands on a few VE heads. I don't think there were any performance parts done to the VE even in Japan. JWT does have some things for it like an ECU program and they even turboed one for someone here... if he cares to make his presence known... but I think we all know who he is anyways. I'm opting for the DET swap myself as soon as I have the money to get the basic parts for it. I dunno... about the Diet vs regular thing though... Saving all my money for my car which means I only drink water or generic Food Max Real Dr. soda... =)

Bubba Zinetti did the monster VE thing on here. If you have money, go for it. But be prepared to spend a FORTUNE since the VE is expensive to get to start with and then to mod it you have to go mucho custom cuz no one make diddly for the VE (besides the JWT ECU). If you want bang for the buck, do the DET route. Tried and true. Only reason I didn't swap out the whole motor is that my car is a 98 and I can't see throwing away a motor that's not new. Now when I blow it like our mis-shifting buddy Mike Gosselin
, then I'll grab a DET.
Or since I already have the turbo parts, probably just grab one of those el-cheapo Primera motors and shove low compression pistons in it.

With $2500 I think your only choices are an FMAX stage I or a DET w/a few mods. I'm pretty sure the stage II costs a bit more.

These are a very good options.

The bigger hp option is a DET (GTI-R if you can get one) w/S3s and FMAX stage II. You really can't go wrong with this combo.

The VE is a neat option for people that want something different and don't give a **** about $$$ or going through some difficult periods/bullshit. Remeber that the VE is 11:1 from the factory so you need to swap the slugs just as you would for the QR (unless you use the VE head only). But if you want to bore-out the motor anyway for added (tiny) extra displacement - it doesn't matter. I think the VE head flows even better than a GTI-R head but this is only an opinion as I can't prove it with data. The mechanical lifters are also a plus. The cams are a minus as they have a LOT of overlap. Cams can be fabbed but this costs $$$.

The VE WILL NEVER have an aftermarket to speak of.

I don't think judgement should be passed on the QR yet. Knowing Nissan, the motor will be, at the very least, interesting. Square bores are best, but not the be-all end-all. I have never seen a QR but I am sure it will be miles ahead of a Chevy motor. The big three seem very tech-averse. They only know "cubes=power" and must design big motors to make up for their know-how deficit. Their small motors are pitifully weak and their large motors look inefficiently silly. Think what skilled designers could do with all that displacement. They are relegated to selling land-boats.

Too bad, as of now, so is Nissan.

SERvo asked if the QR20 is square... actually, it's undersquare, ie. 89mm bore x 80.3 mm (I think) stroke. The QR25 is basically the same engine stroked out to 100mm...

Oh, and there are aftermarket cams for the VE over here in Japan, I believe, but I'd have to double check that... there is a small domestic Japanese VE aftermarket, as the engine is used in at least 4 cars (Primera, Avenir, Wing Road, Bluebird SSS) that are all fairly sporty. (Well, the BBird SSS is sporty if you're over 40 years old).

Personally, if I wanted to piss off the VTEC boys, I'd try to find a 200hp SR16VE N1 engine and slap it in an NX coupe... expensive, but satisfying.

Hey Masuzushi could you check on those cams for me? I'm looking for cams w/less overlap (for turbo). I'll bet all of the cams there are for NA (more overlap).

For anybody who cares - NA applications usually do better w/more cam overlap. Turbo motors usually put out more power with LESS overlap.

also Masuzushi...
do you have the NISMO 2000 catalog? I'm interested in some seats but can't read the dimensions. Any help would be appreciated.
