Not sure what you mean as a stand alone...
But I don't know what gains would be, I assume you'd pick up a considerable amount of hp around 7,000rpm and loose torque in general.
I know one of our members used these cams + hr valvesprings and made power right to 7500rpm on his built turbo setup so I'd assume NA would follow a similar trend.
Really when you think about it, aside from a retune and the intake plenum the only power making difference between a rev up and de is in the cams.

 

Do you have a link to the build? How did he do it use DE exhaust sprockets on HR cams?

Even better why go through the effort to do a full junk yard build as above to gain minimal HP? With HR cams on an NA build wouldn't you lose a lot of torque in the mid range....where you spend most of your time driving? I still find it hard to believe they fit when all cam manufactures differentiate between DE, Rev-up and HR cams and go as far as to same they are not interchangeable?

 

Search it

I'm just stating what I found, as advocated on maxima forums. I can ask BLDG one more time but he told me privately that's what he used in his build (he had the Jtran gt40 build on here).


But it's not a junkyard build. Milder than 264's for a quarter the cost (most hr cams go for like 300usd) that can flow plenty out to 7500rpm, further than most builds require, with probably a better midrange. Valvespring set for HR's can be had for about 115usd. The HR valvesprings actually can take quite a bit of cam lift.

I trust the maxima forums as they dabble with pushing oem related parts a bit more than us, and many of them have experience with vq's since the 30 days...

For what it's worth though, I'm personally going to run a full bc setup w/ 272's.

EDIT:

When is it a good idea?

When you are building your motor. Let's say you are on a tight budget, hr/rev up cams + valvesprings would be about 460usd (I found shipped) without any hook ups. That's a hell of a lot cheaper than cams (alone without valvesprings). Bundle that with a 189$ rev up oil pump and your de can flow out to 7500rpm and be technically safe. If you really wanted to play it safe you could get a billet girdle for another 300$ and you'd be looking roughly at the same price as cams.
I think that HR/Rev up cams would be a better choice than DE cams by a country mile if you are real broke and brand name cams are out of your price range. There are a lot of stock head builds out there, this is a setup that wouldn't cost very much more and could give you a bit more hp and some more rpm to play with. No it's not as good as more aggressive cams, but they are a step up from 9.5mm lift de cams.

 

Try putting 4.0L rods on an OEM 3.5L crank and HR pistons that are fly cut with with some HR cams make some big NA power... prove me wrong


Junk yard build= a build with used OEM parts from several different vehicles....pretty much what the guy that made the first post in this thread in over 7 years said he wants to do he listed parts from 3 different vehicles.

 

swoooooooooshhhhhhhh!

 

I honestly don't understand what your point is. It's cheap? Yeah, that's the whole point. If you searched you would have found that the cams work on the DE even with the vtc sproket. And I quote from a post : "All that was needed was to source some longer "exhaust cam bolts" he located at some fastener store". No machining was required to put the rev up cams in the DE head.
So lets recap oem DE cams:
Intake Lift: 9.5mm
Exhaust Lift: 9.5mm
Intake Dur: 238deg
Exhaust Dur: 240deg
oem Rev-Up cams:
Intake Lift: 10.5mm
Exhaust Lift: 10.5mm
Intake Dur: 248deg
Exhaust Dur: 248deg
The HR cams open slightly earlier IIRC, and end up having more vavle overlap, but the same specs otherwise.


The maxima guys believe that double shimmed those HR valvesprings won't bind until 13mm of lift. That sounds like a damn good valvespring if you ask me, esp for about 150$ including the extra shims.

These are worth the time/money if you are building a motor but can't afford the 1400ish$ for full cams/valvesprings.
Not everything on a vq has to cost an arm and a leg for it to be good

 

Your reading comprehension is on the low side, the junk yard build he has planned will not work....the rods are not the right length for an OEM 3.5L crank....even if they do fit the HR pistons.

Are you reading the right thread no one has mentioned HR cams not working in 13 posts and no one said he needed to buy better cams or more expensive cams so I am not sure WTF you are even squaking about....his build won't work even if you give him free HR cams the build he listed is a bust

 

Sylvan WHEN DID I EVER TALK ABOUT RODS OR ANY OF THAT?

Let me quote my very first post "I know this thread is old as fock, but I wanted to point out that HR and Rev Up cams work in DE's at least someone I know (member on here) used one or the other (OEM) in his built motor...
Also on the maxima forums they claim the oem ones will drop in.

Not sure what would necessary for the swap but wanted to set that straight. The HR cams would be better for an NA build because they have slightly more overlap, but both cams have 1mm more lift and on both intake and exhaust have 8deg (or 10 depending on which it is intake or exhaust) more timing.

That's for the sake of anyone searching around (like they should!!!) "


Here's what you said that initiated said post: "Neither HR or Rev-up cams will work in a DE..."

You are truly a dumf*ck. Grow up.

 

you seem to be having a hard time following the thread, the guy that bumped the 7 year old thread had a list of parts he wanted to put in his engine.

He wanted to use 4.0L rods out of an engine with a 92mm stroke in an engine and crank with a 81.4mm stroke

HR pistons that he gets fly cut so they don't hit the heads...fly cutting is to make a releif so the valves don't hit the pistons. HR and DEs have different deck heights even if the pistons do physically fit the rods.

He also wanted to use HR cams...the only part you seem to have picked up on.


Name calling and you want me to grow up....have your mom read the posts from 2011 to you so you understand what the discussion is.

The post of mine you quote when you listed all of your cam specs had no mention of cams not fitting or working....so your post was pointless and the name calling I am sorry I mentioned your reading comprehension it seems to be a sore spot for you but you missed the majority of the conversation and seem to think you are the only person in the thread anyone is taking to

 

I will repeat myself for the 3rd time. I only pointed out the fact that hr/rev up cams fit in a DE for people searching through random threads. You stated that the rev up cams and hr cams don't fit in DE heads which is wrong. I just wanted to straighten that out. What we say shows up in searches, regardless if they are only on this site or google or whatever.
Sorry for name calling, I was already irritated before I read your post, but I thought I made it very clear I was only talking about the cams, not the vq40 bullsh*t. I never made any claims for or against his vq40 whatever the fock he was trying to do.

 

Ok we got that in your first post you were only talking about cams, no one argued your point on cams. Yet you kept restating it even though that discussion was over and no one said you were wrong just seemed confusing why you kept bringing it up.

Really the whole thread is pretty pointless and not worth arguing over or getting worked up about.

 

true that. lets lock this b*tch up

 

U should start a new thread about the cams with the proper tags, will make searching much more productive than bumping a 10,000 year old thread that doesn't have anything to do with cams :P
