Didn't they also stick the DEK into the "Limited Edition" 4th Gen I30's, like in 1998-9?
Given that I have a '98 I30, seems like a really good match for my ride.
How does the DEK compare to a similarly equipped DE in terms of 60ft, 1/4mi. and mpg?

Unfortunately, I cannot vouch for the benefits in terms of numbers for the DEK or 3.5 swap. By guessing, I can imagine that the 60ft should be around the same, the quarter mile will go from (If 100% stock minus the swap) high 14/low 15 to high 13/low 14. The MPG should remain close to the same.
My guess for the quarter mile is because the DEK has a Variable Intake Manifold (00VI).

Thanks for the reply about the oil consumption.

I provided guesses. It is common knowledge that the stock 4th gen 5spd does the quarter mile between high 14's and low 15's. Because 00VI generally shaves off near a second (and factor in the benefits from having just the DEK alone), you can expect to shave off a minimum of one second off your quarter mile.
Thanks for the reply about the oil consumption.

The 3.5 will shave off around a second. According to you then, 00VI = 3.5.

Given how many people have done 3.5 swaps, I would imagine there are before/after dynos and time slips floating around somewhere in cyberspace.
Not that numbers, per se, are really that important to me, however, I would have to assume that people who do the swaps primarily wish to change their numbers, either measured directly or indirectly.
Other than having to replace a blown VQ30, why else would anyone do the swap except to be faster?

OK ... so tell me if I am wrong. Just to throw out a number. A good driver on a normal day can run 15.0 in a bone stock 5SPD 4th gen. A full DEK swap should take the bone stock to under 14.5 (I would like to say 14.1-14.3. I remember seeing numbers like this, but they probably had a few more bolt-ons). The 3.5 FAQ says you can expect high 13's with no mods. So I didn't mean to say they are equal.
I should have said that you can expect near a second with a full DEK swap.

I am not trying to be smart @$$, but I would like to know what numbers we can expect from a full DEK swap. I am still stuck between DEK and 3.5. I was under the assumption that a full DEK should get me near 14 flat, but I guess I am wrong. By all means correct me ... no hard feelings on this side.

A VQ30DE will get you to a 14 flat... It's been done before.. N/A. The most you can get from a DEK is the VIAS. Everything else that was improved will not prove to have much significance if any on power output. 3.5L will give you MUCH more in terms of performance all around, especially area under the curve where it counts the most.

The 14 flat represents the faster extreme of the bolt-on DE-K/DE w/00VI and the slower extreme of the basically stock 3.5 w/exhaust.

As was pointed out earlier, the DEK swap is easier, and much less painless to do than a 3.5...so, it all comes down to what one is hoping to accomplish by getting rid of a perfectly good engine in the VQ30DE.
When all is said and done, I think I'll just be happy with what I've got...and consider going the easier route of doing the DEK swap when I feel the time is right.
Sometimes, I tend to think I need to go faster. Other times I think I'm going too fast as it is.

If you're doing an entinre engine swap, just do the VQ35 since not much will be gained from the entire DEK over the DE (3.0L).
If you are just wanting DEK performance, get an A33 VIAS IM.

OK...if I choose to just get the VIAS, what kind of cost are we talking about??

you can find a decent DEK for about the same price as the 00vi setup. Which would you rather do tear down the top of the motor and get the old IM off and new one on, make sure vac lines are in order. or pull a whole motor, and drop new one in, plug any holes needed, maybe some adapters, wire up new injectors...etc.
the DEK is pretty much the same as the DE, cams are slightly more aggressive.

Moreover, I intend on keeping my 4th Gen until the wheels fall off, and I would like to think that putting in a lower mileage, more spirited engine might be worthwhile in the long run. I do like the idea of VVT, whether it be an 00VI or V-TEC.
And, I guess there is a little bit of that "I want my I30 to be faster, or at least different, than the other guy's 4th Gen I30" running through my mind.

I can go forever. The 5th gen engine electronics, I am guessing, has more compatibility and more closely resembles the VQ30. The 3.5 FAQ explains which cars you can pull the engines out of, but unfortunately doesn't specify which years. If I had to choose, I would take from the 02-03 Maxima or the Altima (Not the 04+ Maximas). Note that I am not the engine expert by any means and this knowledge comes from me reciting information that I have not recently researched, but I am pretty sure it is correct.
Moral of the story ... don't swap to the 04+ Maxima engines.
Now to jack the thread ... Does anyone ever get scared of the oil consumption problems that the 5.5 gen owners report. The horror stories right now have me convinced to do the DEK swap instead. If someone can prove they fixed it or that it is overrated then I will go back to wanting a 3.5 swap.
