Well I searched and saw maybe one thread but nothing was actually mentioned on how to do it. I have a set here and would look to install them when I get the heads ported and polished.

you just need the adaptors from stephenmax that are used in the threepointfive swap

Get the adapters from stephenmax and get started. At bit more complixated that I thought, I think you need to drop the engine to remove the timing cover because of the porky passenger engine mount.

You dont need to drop the engine to put cams in. Remove the mount, remove the front two bolts of the crossmember, lower it, remove all accesories, and pull the front timing cover off (And remember theres 3 bolts INSIDE the oil pan). Ive done it twice in my bros car.

I have some of Stephen maxs adaptors in my hands and do not trust them for reliability. I dont think they are strong enough and I would not risk it. Im pretty sure if something goes wrong the valves might hit the pistons. And you dont want that to happen to you when youre on a backroad getting chased by cannibal hillbillies...

check the FSM on camshaft installation FIRST..

You will be ripping apart the upper part of the block/heads, valve covers, Timing chain cover, and lower oil pan..

doing it with the engine Inside the engine bay is Crazy.. I know because I did it.. ..the location of 10mm timing cover bolts, the need to un-seal (then re-seal) the outer timing chain cover with RTV is gonna be overkill

taking everything off is not THAT hard.. but when it comes to sealing it after the install... the outer timing chain cover is PURE NIGHTMARE.. ALL because it is VERY Hard to install it correctly without smudging the Necessary Continuous bead of RTV Sealant.. And if you DO smudge it, there will be a bad seal in that particular area (leading to oil leak after the engine is broken in and Pushed). And the engine has to be angled in a certain way to put the outer cover on (the large protruding bolt above the crankshaft IS The reason it is so hard to put the cover on INSIDE the Engine Bay.. It makes you install the cover OVER it before everything is sealed, and there is LIMITED room)..

Setting the timing is actually very easy, just make sure Piston 1 is at TDC, BEFORE you start ripping the motor apart. Then line up the chain with the timing marks..

It is also VERY SMART MAINTENANCE to replace ALL 3 timing chain tensioners, so there is no rattling from the Chain after the Cams are in..

basically not a one day job for an Intermediate installer..
a Novice Installer should not even bother..
Confidence, Patience, and the Ability to Overcome Obstacles as they pop up during install will be KEY.

here's a pic of what you will be dealing with once the outer timing cover is OFF:



good luck

These are the rev up cams, right?

MikeSDA

iTrader: (23)

Does anyone know the lift/duration differences between the cams?

Also intrested in details of intstall

Kevlo911

If you get revup you have to get the exhaust cams drilled or "adapted" as well.

nismology

iTrader: (8)

I suggest you get a haynes manual. Installing VQ35 cams is no different that installing 3.0 cams except for the adapters/spacers that you must get from stephen max or someone else. Familiarize yourself with the general procedure first because I have the feeling you wouldn't even know where to start and it's a pretty involved process.

question is, will all the work be worth the power gain?

MDeezy

iTrader: (27)

I would suggest printing out the fsm pages that display the sequence you need to remove bolts.

awaiting answer also...

Umm these are from a 2003 350z, going into a vq30de. And I will most likely be removing the whole engine or just dropping another engine in. Going to be used in a boosted application, they should help a little but with top end since im sticking with the stock rev limit.

stephenlc

iTrader: (1)

Whats wrong with Stephen Maxs cam adaptors?

NmexMAX

iTrader: (22)

Moot point, but those cams are the same as any other 02+ Maxima. Adding 350z in the title is deceiving.

stephenlc

iTrader: (1)

Oh well I didn't know. I got them for very cheap, when did the rev up models start, 2005? I am guessing mine is the first set?

If anyone is looking for an alternative to adapters, I have spacers left and can drill cams.
Just pm me.

MaxBlack97

If anyone is looking for these cams, I have those for sale also. Goodluck on ur project stephenlc, let us know how it turns out.

I might send them to you, Dude kinda freaked me out about stephen maxs adapters.


Thanks I am really excited i am planning to make a custom intake manifold with a 90 mm q45 throttlebody, has anyone used this throttlebody before? I wonder how I can get the tps to work.

Anyway planning to make 400 whp+ on 7 lbs of boost.

grey99max

iTrader: (12)

Could you put one of these Q45 TBs: (on the left)



On one of these 3.5 Pathy minifolds, minus the long runners?



Six individual runners w/butterfiles.....

Of course, this will only bolt to a 3.5 Pathfinder or a 3.0 LIM after shaving long runners, but what a thought, eh ??
.

stephenlc

iTrader: (1)

thats a nice intake manifold, but im going with a more of a sheetmetal looking manifold sort of like the SSR casket manifold for the 350z but with no weird elbow thing.

tavarish

iTrader: (27)

Nothing, BUT they leave a little play in the cams, but that shouldnt be an issue when the cams are bolted down, since they only act as placeholders for the cam sprockets. The ones I used made by tilleys99 needed some mods to fit, but they seemed a lot more rigid and tightly fitting. haven'thad a problem with either, and I've never heard of the cam adapters as a failing point in the swap, as long as everything's tightened down.

pawnstar12

i got stock 350z cams for $120 + shipping

SNOMAX

iTrader: (14)

Also, if you planning on boosting, you would want cams that have as close to zero degrees of overlap as possible.

MikeSDA

iTrader: (23)

If you were going for N/A only where would you want the cams timed?

GRAVE DIGGER ALERT!

What ever happend to this install?

Crusher103

iTrader: (10)

he started his car and it exploded and he died.....3.5 cams b serious bidness......


talk to essential1 i think he has 3.5 cams in his 3.0

MDeezy

iTrader: (27)

aackshun

iTrader: (3)

Z cams or Maxima cams though?? I know of the Maxima installs but I'm more concerned w/ the Z installs...

NmexMAX

iTrader: (22)

What z cams are we referring to, rev up?

aackshun

iTrader: (3)

Scratch that, I read more closely.... 03-05 Z cams = Maxima cams.

MDeezy

iTrader: (27)

look whos up and semi sober...
yea... only the rev ups are different.

for a 3.0 you could throw in regular de cams but if you can get some rev ups and toss em in.

NmexMAX

iTrader: (22)

... semi ,...
t
That was my underlying point ... unless it's a RU, it's got Maxima cams ...

aackshun

iTrader: (3)

I'd still want some results lol.... I have to find this essential1 character

Or I guess I will have to throw them on my car for lolz.

i guy near me had stephen max adapters and one of them snapped causing his valves to get bent, i just drilled my main cam about a 1/8 inch figured that would be alot stronger and also could you use the rev-up heads from the 350z? my boss suggested that just not sure if hey will work...

MDeezy

iTrader: (27)

how did it snap?

once the adpaters are installed and the bolt is torqued down there is no tension or stress on the dowel pin. So basically once its installed and as long as its not broken once everything is bolted then he should be fine.

you could use the rev up heads. not sure if the heads on the rev up flow better than normal DE heads.

For all the work you'd have to go thru putting rev up heads on your motor, you might as well have some porting work done as you'll need to replace your head gaskets and head bolts etc...

3.5pearlmax

yah my boss swears they flow alot better just trying to find some proof that they do...and as for the adapters I asked the kid if he torqued the bolts and he swears he did, i can see that they cant be that strong but if you torqued the bolts they shouldnt move his intake cam spun free and bent the valve in bank 2 i believe (closest to radiator) probably wasnt tight enough but drilling my cam was easy and seemed much stronger i didnt want to chance it

NmexMAX

iTrader: (22)

Are the RU heads a different PN than DE heads? Anyone with FAST here?

MDeezy

iTrader: (27)

yea for 100% assurance drilling and a thicker solid dowel pin

Did he explain how it is much better or proof? as far as memory serves the rev up made more power from a slighty better ecu tune, better cams and slightly better cam timing. Aside from that all the other components, internals, intake etc are the same. Actually i think the intake manifold has shorter runners? or longer?



damn I lost my fast ages ago... wish i could find a new up to date version.

Crusher103

iTrader: (10)

oh btw no extra adapter are need for rev-ups incase anybody was wondering.
