Hello and thanks for reading. Im a new owner of a 2008 350z. I purchased it salvage title (did research on vehicle found all kinds of info on the bin and it was rear end damage ) for 10,000. Handles lile a dream and ive gotten her to 150mph in the low end of 4th gear. It was allrwady lowered. So far ive put a LS Diff and southbend stage 3 daily clutch and light weight flywheel. Ive got about 10,000 I want to put into this car I currently have no real plan or direction. Im looking for advice and mayby some "this is what I would do" 's. Ill be researching the forums and would also appreciate some advice or quick links to threads that funished there build within the 10,000 budget. I just finished a 700 hp build on my 4x4 f350 diesel at truck source . Ill be concentrating on this vq35hr build for now on.

 

Indeed.


Assumptions used: stock gear ratios (trans.), stock final drive (rear), stock height rear tire 26.68 (18" tire).

Gear limitations are a bish.

Oh, horsepower is not the issue here. Only requires ~160WHP at the contact patches to achieve 150mph.

ASSUMING 0.00 cD.

Ummmm....

 

Well gee, nice to meet you as-well. It's good to know the moderators will be so helpfull. Well, (for full disclosure) I may have been at the top of 4th or the bottom of 5th im not quite sure. All I really remember is looking down after hauling *** through some gears, saw my speedometer creeping ever so close to "150" thinking and blurting out "oh ****" and begain slowing down. I liked that feeling, and want more. Thats where you guys come in.

 

Yeah first you shouldn't be driving that fast


2nd you were at the top of 5th most likely. So you trying to show off here.....failed in your face

 

Nobodys trying to show off here... Came here for some friendly advice on what direction I can go. Thanks for the douchy ridicule.... Well, so far z has been lowered, it sitting on 20s with low pros, I had a limited slip diff put in, and a srage 3 clutch. Ive slso put in a new radio :-)

Im thinking I want to upgrade the suspension first but im new to the 350z scene or the sports car scene in general. I went with a carli king coilover system my truck. anyhoo, im also thinking about stillen exhaust and headers but I may go with a turbo so I dunno. Not really trying to push more than 450 hp on this. I like the stillen cold air intake to. Any advise is appreciateed

 

Sean, you're new here and don't expect you to know anything about me. I don't ridicule anyone. AS A RULE of life. I do, however, point out things from a scientific perspective just as I've been shown to be in error throughout my life.

So, please don't take it as ridicule. Merely a point in fact.

This board has a TREMENDOUS AMOUNT of knowledge to tap into and where I can, will always offer my assistance, in any subject matter that my experience can offer.

So, if it makes you feel any better.... Welcome to my350Z.com and really nice car.

S'far as advice.... the HR doesn't have as much - in the way of hardware - to offer it, unlike its older brother, the DE. Turbos, superchargers are still rarified air (pardon the pun) for the HR. Probably the only turbo system available for it readily is the Greddy system. Expect to pay near $10k JUST FOR THE SYSTEM, no supporting mods included, e.g., better brakes, suspension (which you already have so that's a plus), etc.

Bolt-ons such as plenum spacers, cold air intake, exhaust systems are available (not the plenum, that's DE only) but net gains with any/all of these installed are miniscule.

What the HR engine can take advantage of is it's higher RPM limits through a set of performance gears and possibly a good LSD depending on type of driving you do. Go 3.70, 3.90 out back and acceleration picks right up (of course, at the expense of a bit of top speed but....)

EDIT: Just went back to see that you've already gone LSD. Did you retain stock gearing? Lowering to 3.90 from the stock 3.54 makes a WORLD of difference in application.

The HR also responds well to performance ECU tuning but BEST if tuned after any intake/exhaust changes. Of course, a blown engine responds more critically to tuning but it's still worthwhile NA.

Again, you haven't been around here long enough to really know what makes me the butt of all jokes.... Driving School. I say it probably once a month on average.

But while it's preached as something of a joke now, I am deadly serious about it. NOTHING improves a car's performance better than a tuning of the personal gray matter and the mind control over one's control features... eyes, ears, butt, hands, feet.

So, can you build and handle a 450 pony HR? Absolutely, but it takes more to get it there. Take the money and invest in a performance school and, as I always end with, "It's the cheapest and BEST modification you can make because it carries over to EVERY car/truck/van you'll ever drive."

 

Oh, and by the way, my first post which you took all wrong was a helpful bit of information.

Gear limitations, aero drag and all of the associated things that keep a car from reaching a higher terminal velocity can ALL be planned out in advance, the smart way to obtain your final goal, whatever that is.

There are planning tools (like the gear chart I showed) that can help to predict just what a car's baseline performance is and allow you to set realistic goals about the ultimate performance; instead of just saying, "I want 450bhp."

That's all fine and dandy but..... what do you want that 450 ponies to do for you? Max acceleration? Top speed? Bragging rights? (And that's OK too, just s'long as you're honest with yourself and plan it all out accordingly.)

Make sense?

 

bwaaaaaaaaahahahahaha

 

sure sounds like it. how about you take the car the direction you want it to go, the car you have has been out 8 years, there is plenty of information on it if you look.

 

I think were all getting off on the wrong foot here, I really would just like some honest advice on what my platform is capable of. I have no defined goal as of yet. MicVic thanks for that driver course info, I did one when I purchased my motorcycle really glad I did. but i do believe you misunderstood my query. This is the 1st "sports car" I have owned, I bought the car on a whim and it is not my daily driver. My 10,000 dollar budget is just a limit as I tend to go overboard. I never said I want 450 ponies, I said im not interested in chasing anything past that down. Not sure if I want to boost it ether.

So, if you had between 10 and 15 grand and a base 350z with a southbend stage 3 clutch and a limited slip rear installed what would you do? I was considering the stillen supercharger kit and other support mods. But this is no way my world of knowledge. I do know diesels pretty well but thats it. I would definitely use this car to drift, I have 73 camaro that I drive in straight lines.

 

MicVic yes I upgraded the final drive to 3.9, so far ive noticed that my cruising speed has gone up a few hundred rpm. Also the clutch is like butter, took a sec to get used to the new grab point but I really like how effortless the shifting is.

 

The problem is first you trying to be cool talking about hitting speeds you should be in jail for


Next is the fact that your what's wrong with the car scene. Everybody wants opinion what to spend their money on their car. Do what you want to do. Everybody is going to have a different idea of what to do


Lastly I'd do suspension and get smaller wheels

 

I dont know about what these other jokers are talking about but the first thing I would do is throw them big baller 20s on craigslist and get some new wheels...

 

Ok, suspension and smaller wheels. I know that currently all the car has is a lowering kit. Ive seen a bunch of different stuff out there in regards to suspension. Are the tuner suspensions the right way to go or are they over complicated? I like the idea of being able to adjust on the fly

 

Lol, the 20s came attached. I hadn't considered changing them. I was thinking some white rims but exterior mods wasnt even on my mind right now. Personally I do like the off set look.

 

You won't go much over stock hp if you don't boost it. Full bolt on with a tune MIGHT get you to 300hp. Fully built motor with a stroker kit will get you north of 300, but you could spend close to the same money on a twin turbo kit or supercharger and make over 400hp.

Also, there is tons of info on this site. It will require an investment of time to extract. Don't be surprised when nobody spoon feeds you all the info you seek. Check out the tech area forums. Use the search. Everything has been covered, probably a few times. Most people here don't mind to help if you do a little leg work first.

And yes, ditch the 20's.

 

Doesnt the vq35hr produce 306 stock?
The only turbo kit I found was a twin kit from greddy for about 10k. Can I get 400 out of 1 turbo, and is there a kit?

 

FI makes a twin turbo kit for the HR

 

306hp at the crank, which is probably 250-260hp at the wheels, where it matters.

 

You could probably find a really generously set up dyno that will tell you its over 250... If your going to sink 10-15k into this why not just get a 370z or something that doesn't have a reconstruction title... I would just drive and enjoy as is, maybe throw on small things but your basically throwing money away if you already have a drag car, and a sweet redneck truck.
