Moving on from 350Z to a 370Z
 
Hi guys

Just want to hear some feed back those of you who did the same move..

I have had my 350Z for over 8 years, in the first place I HATED the Z so much because I was very used to lighter rwd cars which had more power than the 350Z. 1450kg of weight, rev limit of 6600rpm, very understeery and weak suspension setup, viscous LSD and etc, there were just too many things I hated about. Driving this car on race tracks or mountain road was a joke and I hated every single bit of it because it felt so dull, not responsive and etc. I originally imported the car from Japan for a quick sale and cash but somehow the mod bug bit me and made me to turn the car into something that I appreciate more..

As time went by I slowly started to mod the car up with a lot of trial and error and finally came to a point where I was happy and could not really do much more to improve it other than rebuilding the short block to gain more capacity and compression, which I just did could not justify the benefit of doing so when the HR models were already out for ages and now the 370Z. When I did the cams and valve springs to bring the engine to 7200rpm, the car felt so much better but after a while nissan launched an HR engine with 7500rpm limit, which pissed me off..:owned:

I recently sold the 350Z to a very close friend of mine who was looking for a trackable street car, and the new owner is very happy with his purchase and I still get to drive it at the track occasionally which is also a good thing, he is looking for some excuses to spend some money on the car but having a hard time finding those :rolleyes:

I sold the car because I was not driving it enough after owning too many cars, the Z was rarely driven and only time it gets driven was when I was attending track days. As work got busier and me getting older :bowrofl: I just did not have enough time to drive it, done less than 2000km over the last couple years. Anyway, so I sold it and after taking my other cars to the track for some giggle, I realised how much I miss the old Z. I was telling myself that I need to find a new street/track toy, because my 500hp+ bmw is just too heavy and expensive to punish it too frequently.

I researched here and there and I decided to go ahead with 370Z, you can call me stupid but I have never test driven an 370Z yet but still bought one off auction in japan and it is on its way to NZ right now :rolleyes: It is even heavier than the old 350Z although it is not by much. Looks like it is lighter than the HR models at least.

Those of you who track your 370Z and preferably the ones who moved on from 350Z or have experience of modding 350Z, could you help me giving me some information.. On the spec sheet the 370Z beats in almost every single aspect but how about in real life?

1. I am assuming the 370Z should feel much more nimble despite the fact that it is still a heavy car, compared to a stock 350Z for its much shorter wheel base and wider track, less caster etc. How is the suspension in the stock form? I know I will be getting a set of coilovers and probably sway bars once the car gets here but just wanted to get some feedback on its handling in general.

2. Flywheel weight of the 350Z was very heavy, and I assume the 370Z probably will share the similar weight if not heavier. Has anyone experience with any particular light weight fly wheel?

3. Final drive and LSD, I just cant live with viscous type LSD for it being so unpredictable to the touch of accel. back then when I was doing up my old 350Z up, Cusco RS was considered as the best and almost indestructible LSD, which actually lasted almost 8 years of my abuse and still going strong. I did some research here and it appears that OS Giken LSD's are now much more popular for its smooth engagement? Is final drive swap a popular mod among 370z owners? I was running 3.9:1 ratio for the 350Z which was about 10% shorter than stock. And from memory 370Z's stock final drive was around 3.7:1, and I think I remember seeing 4.1 or 4.2:1 kit out there, has anyone had a good experience with those kits?

4. Power mods - it looks like the 370Z gets close to 400bhp (or should I call it 20%+ gain) with basic bolt on's? this is really impressive, is this very reachable or is it just for some lucky engines out there?

5. Bolt on half cage, I cant seem to find any half cage for the 370Z on the internet, which is very useful for running harness and supposedly save my head when I end up upside down :rofl2: I do not intend to go with full cage because it is hard to get it certified here in NZ due to head room clearance etc. Is there any half cage from a reputable brand for the 370Z out there?

6. What the hell, this is becoming an essay. I think I better stop here now.


Sorry about the messy write up, I guess I am overly excited with the new purchase..

Long story short, I guess my bottom line is, how does 370z perform against 350z both modded and stock :bowrofl:

One think I learned from reading up the forum is oil temp issue, which was bad enough on the 350Z as well, seems even worse on the 370Z and needs even bigger cooler.

thanks in advance for any input.. :bowrofl:

1. slightly more nimble. less tendancy to understeer, thats for sure. handles very well for the GT style suspension on the car that isn't too harsh on DD'ing. with that being said, u will still want coils for tracking

2. yep! this flywheel is a heavy sob. a bunch of people have gone lightweight, and they will have to chime in here.

3. can't comment much on LSD swapping. don't think its real common. same with final drive swapping, although i know there are members on here with both done.

4. you can expect 325whp+ with full bolt ons pretty reasonably. i made 326whp without headers (just test pipes). If you go with some nice long tube headers, intake, exhaust, and tune, you should expect somewhere around 325-335whp. (which is about 370-375 crank hp). some members are hovering north of 335, but its not totally common.

5. not sure on this one at all

Just make sure before u track, to get an oil cooler, as u stated. also, a set of track pads and higher temp fluid are a MUST for long track days on this car. other than that, its good to go.

You will love the refinement of this car compared to the 350z. there is really no comparison on interior quality.

P.s. if you go boosted, u can run 500+whp alllll day on these stock motors.

Joepro 02-05-2014 10:19 AM

Love the 370 compared to 350 never looked back. The 370 is more refined and of higher quality as a, whole...in terms if performance the hr 350 compares well when na. If I were building a track car between the two I would pick the 350 it is more basic and easy to rip apart. As for a street car, 370 all the way.

SmokeEater27 02-05-2014 10:47 AM

Congrats on the 370 purchase..Never owned a 350 so cant speak on it personally. I came over from a bmw E46 coupe and the two together are complete night & day IMO. Not to mention the price difference in parts. I have to say youre a lucky man to get to enjoy the car scene in NZ as well as having D1NZ out there. Hope the new Z treats you well man.

You had a fully bolted DE? Tuned? Like others have said, around town you wont notice the "speed" difference too much. Though the 7500 redline is a hoot compared to the 6600. It is much more nimble, and grippy than my old 350. Its faster too, especially when the tach is past 5. Slightly faster than a stock HR due lower weight and flatter performance envelop. I track mine at a Florida raceway, I have a 2013 so the oil cooler is stock, all I do is put on tires and brake fluid, pads in. Havent had any issues. Yet.

Thanks for the information :tup:

It is interesting to know that the new engines can hold 500whp all day.. the VHR engine must be real tough? I never looked at boosting my DE engine because of their known weak conrods and bolts issue, I couldnt see point of having a time bomb that you cant really push hard and limited to low boost :shakes head: unless of course you rebuild the engine with stronger parts and run less compression to accommodate higher boost.

I think I should read up a bit more regarding boosting the engine but I know I will be staying NA for quite a while. :tiphat: Knowing that the engine can hold 500whp is really cool though, that probably means like what.. 10~14psi of boost on stock engine? is it really safe? :eekdance:

kenchan 02-05-2014 02:56 PM

if you want safe, keep it stock.

Yes, I'd say it had full bolt ons.. the DE engines dont really get much more power from bolt ons though (compared to what I see from here in 370z scene), for me the real game changer for the DE engine was the camshaft and moving the torque curve to peak at around 7000rpm. But even with all those, it is very rare to see 300whp.

And yes, definitely tuned, as it is very necessary when running different cams in the DE mainly because the variable cam timing goes out of wack and you lose power in low and mid range.

Regarding the stock oil cooler, where is it mounted on a 2013 model? I saw this nismo option oil cooler that has the cooler in front of left front wheel with ducting.. looked very neat but $$ for an oil cooler kit :ugh2: What was the max oil temp you saw at the track? :tiphat:

:iagree: I never trusted those bolt on kits because it is generally asking for trouble down the road.. but still, that is really impressive number. I wonder how how the engine will get with such power if it is already overheating NA..:eek:

kenchan 02-05-2014 03:18 PM

my Z is an 09 and no oil cooler (factory or aftermarket). no issue on my car.

and no, we should not discuss about overheating as thats been discussed waaaay too many times.

rather we should talk about wat we had for lunch. :yum:

My '13 370Z is a slight improvement over my '08 350Z. I still think the 350Z is more aesthetically sound with a better exhaust note, but the 370Z's interior is so much better and the more agressive exterior adds character. The extra horsepower is also a plus.

Is the Z34 a better car? It sure is. Was it worth the upgrade? Probably not.

hummmm... i never liked the 350Z's shape. the 370Z took my breath away as the G35C did when i first saw them driving around on the streets.

bestmotoring was siding more on the 350Z's too. but i think they went out of business so that kinda tells you wat their videos and their opinions were worth. lol :D

it has a water jacket oil cooler. essentially a water cooled sandwich plate between the engine and oil filter. get a good 25 row and call it a day. they are a pretty easy bolt on and make a HUGE difference. im talking like 30 degrees dd'ing in summer

not worried about moisture in the oil that you cant boil out during your commute?

looks like its got the same water cooler like the 350Z then, to be honest it did not seem to really cool the engine down much in the old Z, and if you think about it, it is using hot coolant which sits around 100degC, compared to air which is under 30degC and its surface is just too small. In my old Z I put on a small oil cooler first (I think it was 12 row or something) and I was still hitting 150degC (302degF), so I replaced it with 25 row or so and it brought it down to around 130degC (266degF).

I am getting an oil cooler for sure anyway because I cannot see how the car can handle the heat otherwise. Thanks again for the info :tiphat:

nope. car doesnt really come out in anything below 45-50 very often. as long as the oil temp gauge gets to within a low operating temp, then i don't worry

The car has arrived at last..

It came with Nismo LMZ5 wheels and Fujitsubo muffler (just the muffler and stock piping..:shakes head:), gonna get the mid pipe fabricated between cat and the muffler soon.

Put on 25mm spacers front and back, stillen oil cooler kit is going to be installed this weekend :tup:

Very nice. I like your plan. Since Steve Millen is locally known, I got the Stillen exhaust and intakes. People know it is my car, vs any other, when I go by.
