I've only driven my DE and have no intention of parting with it, but I'd be curious to know how the HR and "rev-up" engines feel. Peak numbers don't tell the whole story. I think the DE shines in low end and midrange grunt. It'll rev and it's happy doing so, but it's a journey. The Z isn't slow and it's still faster than most cars, but even 50 more ponies wouldn't help it from being smoked by today's rockets.
@@PhilipTamorriaThought you might like to know: over the weekend, I replaced the spark plugs and installed a Z1 Motorsports plenum spacer. The spark plugs are a bit of a pain in the arse by themselves. There's just a lot of crap in the way, thus many things must be removed. The plenum spacer itself wasn't too big of an issue, but the most surprising aspect is related to reinstalling the strut tower brace: trying to find that fine line between clearing the engine and the hood. Tightening up the brace helped, but not quite sure I'm done tinkering. However, it's money well spent. I did replace the original gasket and followed all torquing specs, and don't think I have any vacuum leaks. The result? It now growls at mid to high range. The intake is reasonably louder, in a good way. It does seem like it pulls better in the mid and upper range, and it urges you to push it. Glad I did it, but I think we're on the same page: compare before and after, and not "after" to a 20 year newer sporty car.
I have an 06 rev up manual that i absolutely love but i still want to upgrade to a hr just for that little bit of extra power, especially top end. Ive driven a lot of cars and the 350z is my favorite drivers car of the bunch.
Great video, I wanted to add another major point- The weak link of the DE is the connecting rods which fail beyond 400 wtq. The thing is, after a regular VQ35DE has connecting rod failure, everyone pursues a full engine rebuild (and why wouldn't they, it's a great motor). However, I have not seen anyone actually replace the connecting rods and pistons properly BEFORE failure and test the new limits. As far as I've researched, once the connecting rods have been dealt with (combined with strengthened hardware), we don't actually know what the next failure point is!! Would it handle as much as an HR? Possibly so. Aside from connecting rods and a few miscellaneous parts, the DE is known to handle as much big power as the HR's do- despite the 80% internal change, most of these internals are swapped out for aftermarket parts that both DE's and HR's have options for, each with similar strength. At that point with forced induction, it's all about keeping the engine together in one piece - precisely both the DE and HR block are very similar and nearly identical in strength, which explains their similar numbers with big power builds. Like Philip said, just pick up the cleanest 350z you can!
HR is better. My DE was clapped out and never blew. Usually all the DEs are clapped out and for the price of a cleaned de is the same as a HR. I miss my Z
Don't forget Nitesh21 on TH-cam he has an build DE pushing close to 1000hp I don't care DE or HR if you have deep pockets either way both could be built into high horsepower engines. For all the work that went into creating the HR the horsepower gains over the DE is quite disappointing... 20whp difference Stock DE 240whp Stock HR 260whp For example the HR has daul intakes as everyone knows by now those flow 13% better over the DE's 3 inch intake with 70mm throttle body the HR has a lot bigger cams over an DE that's why the top end is a little better the HR also has variable valve timing on the exhaust side of the heads as well as better stock headers all the things I just now mentioned makes only 20whp more over an stock DE which in today's time as you mentioned is not that big of an deal. I am really happy with my DE got the car 7 years already with no plan of getting rid of it, currently it's so to say full bolt on, I got the long tube intake in 3 inch diameter, 5/16 plenum spacer, custom exhaust (single pipe system) however the mod that made the biggest difference to me was the Headers I went with Long tube headers it made the car sound a lot more like an HR/VHR for anyone that knows how the VQs sound my DE sounds a lot more throaty and not like the good old trumper sound the DE makes I then tuned it on Uprev which I must say made THE Biggest difference to how the car performs the DE headers are absolute dog water... If you want an DE with better performance I would recommend getting stock HR or VHR headers for your DE (Yes they bolt up to the DE engine) however you will then need to change your exhaust from the headers down to the mid pipe as the DE test pipes and Y pipe won't work Second add an Plenum spacer if you want usable power get an 5/16 it helps with mid range gains compared to the 1/2 Inc that adds so much volume it only helps at top rpm and lastly you could just get an k&n filter drop in and go tune it trust me you will make an good 20whp to 30whp gain on an DE with those mods which is not bad for an VQ that has smaller cams and no variable valve timing on the exhaust side of the engine
i have to say with owning a DE i have some conclusions after i started building it, a lot of people opt out for the DE because it’s cheaper and a great entry level motor,i’d say that the DE is very reliable and that many people get the De and the DE revup in oil consumption, the revup is the oi eater, and another conclusion is that a lot of people don’t know how to build a real DE, because of the fact that many owners of the DE cars are new car enthusiasts and want a cheap affordable car, leading to cheap affordable builds, with cams aftermarket manifold , e85 and test pipes you can make VHR numbers
DE But, honestly, having had my Z for almost 10 years and having read and watched all the videos, there's really no difference between stock. When you get to the numbers at the wheels, the difference is literally almost nothing. It's not enough to be argued as much as it is online. My advice has always been if you find a good Z, buy it! Don't worry about which engine it has.

really enjoy your videos, feels like a big brother giving his advice on cars and life. thanks dude
Thank You! I appreciate it brother💯💯

@@primaltone definitely one of the best mods for our cars 💯 thanks for the detailed update.
This is true, I’ve beat HRs in my DE a couple times.Maintenance plays a big roll for sure.It feels like the DE has more torque.

What kind of microphone are you using? Audio quality is great !

@@dheerajrajeevan4867 Thanks for this! I appreciate it. 💯💯
Went from an ‘06 revup to an ‘08 350z and the HR is far better with no oil consumption and the power difference is very noticeable
It’s not a big power difference in my experiences. Definitely a better powerband with more top end etc
HR is better. My DE was clapped out and never blew. Usually all the DEs are clapped out and for the price of a cleaned de is the same as a HR. I miss my Z

I would worry about the transmission. Yiu want that cd009
I’ve had it for 13 years, no issues

Thanks for the info! Good stuff!! Why the HR headers though instead of aftermarket DE headers?
306K miles on my 2006 G35 sedan DE with original motor. 2 owner. Trans swapped with 40k one from wrecked Z
Nice! That’s pretty solid 💯💯
De has a nice tone
