3.5 Bottom And 3.0 Heads Finnaly Running
It would be a lot of headache. 3.5 internals means crank, rods, and probably cams with the 3.0 block and 3.0 pistons, so you get more stroke with the same bore. Thats a lot more work for less power than just putting the 3.5 in with 3.0 timing.
I would just throw a set of 3.5 cams on your DE-K. Get them drilled and buy the JWT spacer. The amount of power you get would get you close to a 3.5 swap and it would cost you a lot less.

From what you say, the 3.5 swap using 3.0 sounds easier (as long as I don't get an oil-burner lol). I wanna take my car for another 100k but if I were to get it rebuilt I'd rather have the higher hp 3.5
Thanks for the responses btw
PS: do 3.0 heads have to be bored to accommodate a 3.5 block (not for fitment but for airflow)?

Hmm, I was wondering about that (3.5 cam swap), but wouldn't that just push existing power around the power-band instead of adding new hp?

If you run the 3.0 head you would want to p&p and match it to the 3.5 block. The 3.5 head flows better stock against the 3.0 head.

If you have a strong DEK, look into a V1 vortech setup instead. My 3.0 had only 75k miles on it when I swapped to a 3.5 with 81k, but I wanted reliable power without stressing over belts or worrying about a turbo popping my engine.

I suppose using low compression 3.5 rods in a 3.0 block is no good?
Not sure what benefit you would get with the 3.0 heads on the 3.5 block. It looks like a modified 02VI is the best intake manifold (modified for more plenum volume or with phenolic spacers to lower temperatures and lengthen the runners) and the 3.5 cam is better than the 3.0 cam.

But I don't know of any competent shops that know how to put a 3.5L in a 00 dek (using 3.0 timing and such)
From my research, I'd use low compression pistons over a 3.3 destroked. Arias pistons for the 3.5 are ~$800, 8.5:1 compression, and also do ARP rod bolts.
Shop wise, I am sure you can find one, but if they have never done it before understandably you will pay more as they have to sort of learn the process. I used JE Imports, they did a great job if you want to look into them.
For the hassle and $, I would sell the 00 and buy an 02, you would then still have working variable valve timing. Otherwise, just supercharge the stock 3.0.

I kind of want more reliable power myself. I've considered boosting, but I already have a turbo DSM, and I don't want two boosted headache cars.

Nah the only other VQ I built was for a boosted 3.5 for a buddy of mine. Now I'm all into my chevy LS2 build, it's finished just have no idea when I can get this motor swapped into something.
I'm so behind on the compatibilities of mixing VQ parts, I'm sure others will chime in with more info.

My dek is my DD (dsm is my project car), and I wanted to rebuild it to make it last even longer. But I figured if I was gonna rebuild it then I might as well go for the higher tier parts.
I wouldn't mind spending $2000-2500 on a 3.3 crazy as it seems. Beats car payments lol. But would you or anyone else know how much a full 3.5 swap cost (roughly)?
I may go to turbotrix, they built my dsm engine and ported the heads .20 over.

Read Tom's thread on this setup:

compression boost might be worthwhile but it is a lot more work.

My blue print fully balanced DEK 3.0 - 9.25:1 C/R with 1mm oversive valve,double shim, HR spring, manganese/bronze valve guide, full P&P and VQ 35 cam should tell us soon what the 3.0 is capable of. I dont think any DEK has been build to that level so far but I'm curious to see how it will perform, I have build it for boost ie: S/C SI or T trim. I'm off for a month and I will try to finish to prep the car this month. Check my thread for news on the build: http://forums.maxima.org/all-motor/5...roject-30.html
