here are some pics of my new cams i got for my 3.5 today. yes, they're 3.0 cams. i'm using them without the variable cam timing so i am using 3.0 ones.

 

So you're putting 3.0 cams into a 3.5 engine into a car supposed to have a 3.0? Cool.

 

Nice, who makes them, and how much?

 

jwt and a little over a grand

 

you did engine swap?

 

yeah working on it

 

Wow! I think I'll be ordering my set next week, how long did it take for you to get them. Are you swapping the entire engine or just the short block?

 

just the block and heads. and it took like a week and a half. if you want them i can get them for you

 

i boght a wrecked 2003 3.5 max very cheap(puerto rico) because im planning to do the swap but i want to swap everything if possible engine tranny(6spd) and anything else i might need so any advice will be welcome im starting this project next month

 

i would love to hear how it performs after your done, keep us posted.

 

Are you keeping the 4th gen intake manifold? Do you get them straight from JWT? Because they are about 30 min from my house.

i have an account thru jwt and the manifold is from a vq30det but im working on a custom manifold.

 

Oh, I see. Does this mean you can get them cheaper than I can from them? Whats the differance between the det manifold and us?

 

whats your cost?

 

It's $1,100 and tax of course, plus I would be getting the valve springs.

 

DET manifold has no runners and a twin butterfly manifold

 

Coolio, will the cams effect boost?

 

How much are you expecting to gain from this mod?

 

man I can't wait to see the results of this project

 

back from the dead.. So do the 3.0 cams drop into the 3.5 heads without modification?

 

yeah aslong as your using 3.0 timing chain setup

 

if anyone wants to know how cams can make your max sound (with cattman headers) check out this vid.

still one of my all time favorite maxima videos

 

SWEET. I'm beginning to think that this route would be a much wiser choice over the 3.5/3.0 heads setup.

 

Get some results! All this talk is making me excited!

 

3.0 cams in a 3.5... whats next? what will this do?

 

You won't have to worry about the wiring form the 3.5 ecu to the 3.0 ecu....by keeping the 3.0 heads, our upgradable ecus can be mated with the 3.5 bottom end while still using our 3.0 heads, allowing for more power. I actually have no idea what I'm talkin about...But I can't wait to hear more regarding this!

 

3.0 cams, 3.0 timing setup, 3.0 timing covers = FULL 3.5 in a 4th gen. No head swapping involved, and yields more power than the 3.5/3.0 setup.

We can use our ECU's regardless of what head/cams setup we choose.

 

Perhaps you dont' have to swap heads but how would you activate the VI from the 3.5? Wouldn't using our ECU mean that the VI from the 3.5 is useless? If this is the case why would you want the 3.5 heads if you can add a MEVI or 00VI?

 

RPM switch............just like any VI...


The 3.5 w/ 3.5 heads made more power on the dyno according to Tilleys.

Krismax is fabbed a 00VI on the 3.5 heads.

 

So let me take a step back for a second if you guys don't mind...why is it that you're using 3.0 heads and valvetrain, which doesn't have CVTC, instead of the 3.5, which has CVTC?

 

this doesn't make any sense to me... ok you have a 4th Gen max/I30 with a full VQ35DE engine/motor/tranny but instead of keeping the cams, you're gonna basically down grade? Why don't you just get nismo cams for the 3.5 and put the 00 VI intake manifold onto your 3.5... I dont see why would 3.0 be better than the 3.5. You're gonna have a 3.5 shell.. but 3.0 internals. Gonna keep my attention on this thread for sure.

 

u spent on it over 1000$. u think it was a good business??

 

That's not entirely true...you'll still have the increased bore and stroke of the VQ35, and you know what they say..."there's no replacement for displacement."

But I would really like to know why the VQ30 valvetrain, which does not have variable timing, is preferred over the VQ35 valvetrain, which has variable timing.

 

Yeah how about a 3.0 head hybrid with 3.5 block, 3.5 cams, and 00VI manifold?... that's a hell of alot better than a 3.5 block with 3.0 internals no?..

 

Because VQ30 cams are wayyy cheaper than nismo cams, plus you dont need to modify them to make them work, unlike the 3.5 cams you have to drill new pin dowel holes on the intake cams.

It would be a big complication to make the variable timing work in a 4th gen, and it would almost be not worth it, because VCT doesn't do anything above 3k rpm.

IMO, no. The hybrid involves head swapping, and drilling the intake cams, while the full VQ35 only involes swapping of the cams, and timing chains/sprockets/covers. And yet the full VQ35 yielded more power on the dyno. I think the VQ30 heads are too restrictive for the 3.5

 

that video that someone posted up earlier sounds AWESOME when he revs it, but to truck like for me when at idle.
