DE gang where yall at?

The HR also has much more stout connecting rods then the de and rev-up, which makes the HR a favorite for the boosted guys who don't wan't to invest in a engine building. The HR is better by almost every measurable metric, though the cost to swap them into a Z or G that originally came with a DE or Rev-Up is absurd. You can build a DE or Rev-Up for around the same cost as a swap, in some cases, and give yourself something that will hold 2 or 3 times the power of a stock HR. We specialize in custom VQ engine building and boosting, so feel free to hit me up if you have any questions.

Had 4 DE’s (two FWD and two RWD) and loved them all! Reliable and durable

I'll still defend my de till the day I die :'(

Thanks for the video man. Nice to see a simple attempt at explaining the differences with some aid of the visuals. I already knew the majority of the changes, but it was still useful for me given the way you presented it and with the visuals. Cheers.

we appreciate you taking the time to give a thorough explanation

2008 G35 sedan with the HR. Got the best of both worlds. About to hit 130 running brand new

This is one of the best DE vs. HR comparison vids I've seen. Good detail, thank you. - Keez

I may not drive a car, but my 03 Pathfinder has a DE in it. I love it. 257k miles and still goin’ strong.

Thanks for sharing. I've got a 2008 base manual, I track it roughly once a month and live close to a very curvy mountain road out in the middle of nowhere. For the past 6 yrs I've beat the shit out of mine at least once a week on the mtn road and the past 2 yrs at the track.

Great video, I'm researching this subject currently, thanks a bunch

if you plan on keeping internals stock, buy a hr. if you want to build the engine, de. the cost difference alone between the two cars and you can almost build the DE to hold 600+hp, reliably.

There’s a bigger horse power than 6 for the HR vs the DE RevUp. The DE and DE RevUp did not get measured in the SAE standard but the HR and VHR were.

Keep it up! Try to talk about best engine and transmission combos!

Dude great video. I learned a lot and true the DE is better to boost. Replacement cost 1000.0 to 1700.00 HR good luck. But if I was to build a 650 hp to 750whp I would want the HR for sure. Thank you so much for you input on the great Nissan legacy of the 350z. I got 2 of them

A good watch. I have owned 2 VQ35DE's and my folks have owned a VQ30DEK and now a VQ35HR in their EX35. All are good engines, but I love that sweet sweet HR motor in their Infiniti. Bulletproof reliable and pulls great.

Great Vid good info I like that you left any bias out of it just info Thank you.

I got DE in my '06 M35 and with slightly tuned air intake and exhaust it's still awesome :)

You should do a video on the 35HR heads on a VQ37 block.. I hear it works and does wonders in the boosted world! Great video btw with regards to VQ35DE vs VQ35HR!

Great video! Side note. DE blocks are discontinued in North America and there are none in any warehouses. You will have to wait on one from Japan if you need a brand new one! Don't ask me how I know this! Lol.

I've owned a 2003 Z , 2005 G35 6mt , 2008 z , right now I drive a 2012 G37s and maan.. These cars are really fun. You can also feel the differences. Nice vid man!

I have driven a 350z and a 370z and if I'm being honest, the torque and peak power differences are noticeable but are not like night and day.

Good overview on the differences. The same seems to apply to quite many other parts also. Our european project HR has 313hp so i'm assuming that version was not available in your market area?

I had a 96 Maxima 5 speed with a VQ30de. Older then these two variants but it had 400,000 miles on the clock and was my track/daily. Ran perfectly till the moment it was T-boned by a 4 runner running a red light.

Awesome video, thanks for sharing!!!

Nice! Liked and sub'd. This is the most informed DE vs HR video that I've seen yet. Even linked to the Nissan motor publications. I also have a copy of a leaked Nissan ppt slide deck with even more info. I bought a new 2006 "DE-revup" 350z manual which had oil consumption issues. I dumped that car early on for a new 2007 HR which I still own today. The HR was/is noticeably faster. But why? The 2006 was rated for 300 HP and the 2007 was rated for 'only' 306 HP. Truth is, up through 2006, Nissan was not using SAE ratings to publish horsepower. Laws changed in 2007 that SAE ratings were required so Nissan built a new engine. I have a dyno sheet with both 2006 (Throttle body spacer) and stock 2007 numbers run on the same dyno and in the upper RPMs (5k-7k), the DE falls off and the HR has a 40HP advantage between 6k and 7k. My 2007 stock was putting down 262 HP at the wheels and with bolt-ons and tune, it's up to 301HP at the wheels. These are dynojet, SAE corrected numbers. So 40 HP difference stock plus 40 HP from bolt-ons and it's surprisingly faster than a stock DE. Below 4500 RPM, the HR only has a slight advantage. Biggest HR win though is that it has a dedicated oil dipstick tube :-). DE dipstick uses an engine oil return passage so it's herd to get a clear read. Another great advantage of HR is that the hot coolant return from the engine is routed to the radiator externally keeping that heat out of the engine. I'm, keeping my HR 350z till the wheels fall off.

My 1st stock G35 Rev Up with 6MT ...I Luv it !

Just picked up a HR sedan. I love the throttle response

Thanks for a great explanation of the differences. I have owned every generation of Z car and have had every engine from L24 I6 to VQ37VHR in my '12 Z34N. I have long been critical of those that say the "HR is better and the DE is junk!" All I can say is "Well, it is and it had better be. It's newer, evolved." Stands to reason that the VHR is arguably a better engine than the '07-08 HR, yes? Again, it better be. And what about the Red Sport VR30DDTT (from the Q50S Red Sport), rumored to be the next Z's (Z35) engine? Is it the supreme Z engine? Again, it better be. Point is, so many "HR is king" people seem to think if they have an HR car, they're so much better than those of us who "only" have DEs. Get over it. And while you're at it, stop referring to '07-08 Z cars (and the matching HR engine Q-cars) as "an HR". It's just a 350Z that happens to have the next evolution of the VQ35xx. After 25 Z cars over 40-some years, including some rare ones and Nismo versions, the only remaining one is my DE powered '03 which I still love dearly.

Bought a rust and damage free stripped 2004 z and put it back together using a rolled 2008 z. The HR motor is a beast, way more rev happy and fun to drive than my previous 03 z that I sold. If you want to build the ultimate naturally aspirated car cheaply the HR is the way to go, HR block, heads and rods with a 3.7 crank and special 12.5:1 JWT pistons along with tomei 272 or 280 cams would be one sick street engine.

You can build a DE to take just as much HP reliably as a HR, the DE Is a way better platform and there’s more tunability for it which is why I’m sticking to this platform

how's my DE's doing?

Awesome video. Informative 👍

I'm really glad you mentioned the wider torque range if the HR. Most people believe that the DE makes more torque simply because of the peak number, when in reality, it only makes more torque in a very limited section of the power band. HR makes more average torque across the whole rev range.

Great video man. Thanks for sharing

Just picked up a 2008 g35 tech pack has the rev up engine drives and handles like a dream!

Which viscosity and brand of engine oil are you using on your VQ?! (Am running synthetic 5W30 on my 35HR because am scared of engine oil pressure issue or so due to using thicker engine oil such as 5W40 although i want to use thicker one..)

Which one is better is really dependent on the use of the engine & budget. The HR is more expensive to purchase and you will need a more advanced ECU to run the dual VVT. Having said that, even though the DE is cheaper to purchase, what would it take to get the DE to make the "300HP" that the HR does? NA: Cams, valve seats & compression bump (then you might have to look at alternative fuels) Boosted: Lots of heat, complexity & cost. I haven't run these numbers but it is likely that your $per HP is better spent on an HR. Get the HR with a good ECU, beautiful sounding exhaust & then do a ridiculous burnout!

As I get older I appreciate cheaper and parts availability. I love to mod stuff so I'm leaning DE

My Fuga 370 GT has 11:1 compression ratio. I've only had her a couple weeks and I love driving it so much.

how much can each engine support hp wise. I have an fx45 that i love, and have been looking to upgrade to a newer model and want to boost it so wondering which route to go

Oil burning gang, where y’all at?

I recently blew my vq35de and wanted to swap it for a vq35hr I was wondering if the trans from the vq35de would fit in the vq35hr or would I have to buy something else to make it work ?

I appreciate the DE always 🤞🏾

Thanks for the informative information I’ve been trying to decide which 350 I would rather have definitely an HR

Doing a head gasket and up rebuild but considering a vq37hr swap on my g35. Opinions?

To be honest, I'd side with the DE over the HR, the reason being that replacing the GM3800. while the 3800 has been abuse-proof I like the VQ noise, and retrofitting that in place of the geriatric donk would inject a lot of life into my ol' bore-a-door. Ignoring mating up the 'mission to the engine, I wonder if a more lively bent six would be better than the factory lazy six as a daily.

One wrong thing. the 2006 350z got the regular DE if it was an automatic

I had 35 anniversary Z. With Rev up. Great car. 7k redline. I should of kept my Z. The vq was a very reliable motor. Great weird sound.

Swapping from a de to an hr? & what would be needed to make the swap possible?

Great video! Do you know if HR lifters can be used in the REVUP? Or do they all have that coating new now?

I've got a question , how much would it cost to boost up an 06 Altima SE-R . It runs smooth n good but I want to put some power in the whip have a lil more fun.

How close is the 2013 Nissan Maxima 3.5 to being a complete HR I know it doesn't have the exhaust valve timing I know the specs says 300hp but as far as compression is that 2013 Maxima VQ the same as the last Model G35 before it went to the 3.7

So are All 07 & 08 HR?

Did they fix the plenum issue with the Rev Up version in 2006?

I drive a Nissan murano 2oo6 and and it still goes like it was brand new, just touch that key and that motor is purring like a happy cat lol, every time I start her up I get a chill down my spine from that heathy sound, even the cvt gearbox is still working smoothly and the fuel efficiency is surprisingly good too, for me Nissan is tops deffo, I'm the second owner of this car so never bought it new but its still in perfect condition and even better after I got it as I've done many things to it that a factory won't like rust treating and rubberizing the complete undercarriage and wheel wells and many other things, I'll only do that on a car worth it and that Nissan suv certainly is 👍, so many ppl look at my car and ask if I'm not selling it but theres no chance, I've owned a Datsun Skyline 1800 many yrs ago and completely rebuilt and sprayed it and it got stolen here in South Africa sadly but thats where my love for Datsun/Nissan started and this Murano is built much the same way my old Datsun was

Good video. I would have liked to see more comparisons between DE rev up and HR given HR is essentially only rev up. Thanks!

Hello, is the Vq35hr a direct injection engine?

Good info, thanks!

Thanks for info. I have the HR motor

Great vid man. Thanks for the content. How about a vid on VG30 VS VQ30?

Could I change a DE to HR on my 2003 350z? and what do I have to change to make it work?

In Australia the 35th anniversary touring model did get the revup engine

Hi. Is VQ25HR also 80% different from VQ25DE too? I heard it's 50% different but not sure if it's true. VQ25DE can run with normal gasoline while VQ35DE need high octane gasoline. I wonder if VQ25HR can run with normal gasoline with lower octane like VQ25DE too or not. (I don't drive that fast but I like drive smoothly but not too slow.)

I have a 06' Ser (75k), oil keeps seeping into the spark tubes. Anyone know how I can resolve this? Have replaced plugs (ngk iridiums), valve covers/oil etc multiple times & it keeps happening..

Thank you for this helpful information

HR gang!! 7600 red line can’t lose

Just outta curiosity what engine does my Nissan Maxima 2007 SE have ?

Which is better in terms of reliability the DE or RevUp?

How do you fix the plenum issue on a REV-UP?

Finna do the oil change on my DE today 💪

I am looking for this same information on the VQ37 line up

Just got my hr 🤘🏾

Can thicker engine oil such as 5W40 cause engine oil pressure on a VQ35HR since it’s stock engine oil viscosity is 5W30?

Very informative!

What's the engine the Nissan Maxima Spec R from 2007 has?

I drive the revup enthusiast. so far love it!

Im thinking or fully rebuilding my DE, and i believe it has the potential to hang with the HR once all the internal components have been upgraded. Yes, the block is overall better in design for the HR, but like he said, it is cheaper and more available to get a DE rather than an HR. What's your opinion?

I have a great video of my HR sedan racing a 2003 6MT coupe. We were neck & neck at 120mph.... Pretty much neck & neck through the entire PowerBand. (I took off on him at the redlight because my HR is a G35xS & not many people are getting me at a red-light. In any weather condition. I spanked a 392 scatpack the other day because he spun *forever* & admitted he couldn't launch his car from a dead stop without burning rubber. He didn't expect my car to pull the way it did, & even admitted he was going to go home & research some Infiniti stuff since they are always running good around this area. He was cool AF.. (I wish I would've gotten that interaction video)

Where can I find the spacer for the de?

great video man

Do they make the spacer for 05 Altima ser ?

Can the hr get swapped with an all stock g?

I got a first gen Skyline crossover (J80) with a VQ35HR just over a hundred k miles love her never had any issues however this is due to a meticulous maintenance regimen. Since the HR provides so much power the trannys take a good beating if fluid is not changed every 30k especially since the filter is not a "serviceable' during a transmission service they just drain and fill.

My 04 maxima has a 3.5 DE and it's a bit of a beast with my upgrades.

Thanks mate looking at buying an el grand 3.5 know l know what will be better

I love my infiniti Q50 2014 with the 3.7 is a Beast!

Will a vq35de from a 2004 Quest fit in a 2009 Murano?

can you replace a 2002 Nissan maxima with the HR engine with 6 speed manual transmission?

What version of the 3.5 VQ V6 is in my 2008 stick shift 6 speed Altima?

is tis the same engine in my 2004 g35 brembo version car?

Thanks..nice info

I have owned both an 06 base rwd sedan with the VQ35de and 60,000 miles and an 07 rwd automatic journey sedan with 75,000 miles with the VQ35hr and sold the 06 a month later after buying it to buy my 07 which I still own lol I love my VQ35hr it's definitely a great engine

Does HR burn oil like DE?

I see you show Sasha's 350z when speaking about the hr? I thought he ran a de block?

Anyone know if hr and de use the same automatic transmission?

So whats a vq37vhr engine? An improved vq35hr? Or same just larger displacement? Asking because i just bought a M37 my first VQ lol

which one is in the 2019 maxima ?

DE VS REV UP BIG DIFFERENCES? ANY ONE CAN NAME IT? THANKS!
