Now I know what most of you are thinking. But hear me out before you just tell me to wait and buy an HR. (or flame me ) I have been lurking for about 2 weeks, and I have to say that this forum is great. I have found nearly all the answers to my questions without having to start a single thread. But now I need some advise. Basically at the end of my project I want to have a built block for f/i. Now, if I plan to have my engine machined and sleeved. In the end is there any benefit to going with an HR? I know that the mods for the DE are still a bit cheaper than the HR. I'm also thinking that getting a DE block would be cheaper and possibly easier. I'm familiar with the differences between the engines. However I haven't found much regarding built up HR's. I assume that its because most of the 07 and 08 z's on out there are still under factory warranty and most people don't have money out the ears. I plan to finance, and I wont be modding my ride until its paid off. So voiding the warranty is not a factor. I know that there are tons of noobs that come here claiming that they are going to buy a Z and they ask their noob questions and never even end up getting a Z. Thereby wasting everyone's time. However I can assure you that I will be getting a Z its just a matter of making my mind up once and for all.... Sorry about this long winded horse sh*t posing as a question, its just that some how I didn't think asking "Uhhh which is better the HR or the DE? durr" would yield the response I am after.

Oh yeah, I'm new here, Hi everyone. Umm lets see I'm 27, I think I have motor oil in my veins... annnnd after 2 weeks of searching this forum I have deduced that 90 percent of the people that get flamed here.... deserve it. Rock on.

 

For the DE, i think there are more F/I options, there is ST, TT, or Supercharger.. though im not sure if which are still available.. (i have an HR so i havent looked into this)

also, there have been more people using DEs, stock and built and you can go check out their threads and how they;re doing.. the shop builds subsection has a lot of good stuff

for the HR, IIRC there are only 3 choices, all of which are TT kits..
also, in the F/I forum i think none of those HR ones have been built, most are just using stock block, and i think none has had a blown motor, except one which was due to something else..

 

HR... and dont look back.

 

what kind of power do you want to make? that is the question

 

Thanks, I'm gonna go check that out now.

 

+1

 

500 rwhp at least. Although, I don't know if that will stop the itch. But its a start.

 

From a financial perspective:
If you plan to mod, get a DE.
If you want to keep it stock. Get an HR.

For auto-x, get a Revup (06)

 

This is the logic I had drawn prior to starting the thread. Thanks for the help.

 

Aren't there a couple HR's running 500rwhp on stock blocks as daily drivers?

 

As interesting as that sounds, I still plan to build an engine. 500rwhp is conservative for what I want to build, but its a good start. I'de like to look into the HR's capabilities and I know its a definite improvement from a stock DE but here is the question. Would the benefits of having an HR motor be nullified when comparing it to a fully built DE? It seems that Nissan's focus for the HR was vibration and friction and how to reduce it. A lot of the threads I read people are trying to compare the two engines from a power standpoint. Honestly, I cant imagine most people would notice the 25hp or so increase. Such a gain would be considered amazing if your talking about a bolt on, but for a whole engine its not significant. I think that the HR will really shine when it has been on the road for 150-200 thousand plus miles. The longevity of the HR will far surpasses the DE I bet. At least in terms of reliability. But a built engine is a whole different animal and I really don't have enough perspective to compare them in terms of the better project car. Although already I am leaning towards the DE. But please, keep the conversation going, all input is greatly appreciated.

 

i think theres no simple answer to this.
BUT if you WANT to build an engine then get the de. From the price perspective its smater. Id say that the hr is better if you want a reliable engine with conservative hp build that you dont have to rebuild. If your looking for huge power in the future use your money smarter and build the de from the ground up. Youll get more for the money and if you screw something up you can find another on like craigslist for next to nothing.

 

How long are you planning to finance? If you are not going to do any mods for 60 months get the HR now and by the time you mod parts will be affordable.

 

This is something I definitely considered. It is likely to be my biggest argument for getting an HR over a DE.

 

I personally think it would be a waste of funds to get a HR if you are going to build the motor anyways. Get the DE, build the motor to handle the power you want, and you save money doing it that way. The DE can be a strong motor built as well to handle high boost. The HR, I don't believe anyone has built a HR motor yet anyways.

 

If you arent planning on doing any modifications till its paid off which I'm assuming would be anywhere from 3-5 years you'll probably see a larger range of available mods to build up the HR in that amount of time.

I would get the HR

 

DE, or if you want an HR of sorts, get a Cosworth block and heads like I did. Now rev limited to 8,600rpm (N/A) and can go up from there though not advised. You will need the low compression heads for F/I and 500whp is obtainable. Do your research.

 

I have a DE, personally I have not driven an HR motor yet. Don't the HR's have oil consumption issues?

You can easily slap on a good supercharger and get over 400hp on the DE.

Probably going to test drive the 370Z today to get a feel for the HR

 

no, HR's do not have consumption issues, you might find a few special cases but that holds true for DE's too. People are leaving out the fact that if you really wanted, you can build a HR superior performance over a built DE in a high boost application.
