Moving on from 350Z to a 370Z

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 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.


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

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..

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.
