After much debate and months of thinking I believe I am going to be going with the turbonetics kit. I am not a new member I have been here a while so I have read so many of the turbonetics threads.

My Z is my DD so I dont want to run too much boost and don't want to run into reliability issues. I am wondering if there is a 5psi spring that I can run with the kit so it won't boost past that.

My Z has a stock block with 52k miles.. I really hope it can handle boost.. but like I said I don't really want to run much more than 5psi on my stock block because of how paranoid I am... and I drive my car pretty hard..

That being said, anyone have some input for me before I pull the trigger soon? I will be running the turbonetics reflash.

Anyone have any problems with boosting their car after 50k miles?
Is there a 5psi spring I can run with my turbonetics?

I am also thinking about buying a beater for like 1k because I know there will always be downtime and some kind of issues (hopefully nothing big).

Any insight will be great.

 

you can always get a boost controller

 

wouldnt that be less safe than a spring though? I am not sure if they even make a 5psi spring, so I guess if they don't this is an alternative.

 

just do a compression and leakdown. give ya health of the motor right away. Just run the stock wastegate spring. Thats what the turbonetic flash is setup for. It wont be more than ~350 hp anyhow. way safe.

 

Can you name some reputable shops that can do a compression and leakdown test for me? Estimates on how much that will cost?

 

Boost controller wont do jack when it comes to lowering boost.
There's a lot of people with 50K + mile Zs running boost, I wouldn't think much of it.
install the kit, if you're running anything aftermarket like exhaust, y pipe and so on, get a utec and get the car tuned! even if you're running a stock setup with the stock remapped ecu, I'd still dyno it and check out your A/F just to make sure its on the safe side.

 

There is a 5psi spring for the evolution wastegate, but I have no idea if its included with the actual 350z kit. If you buy a evolution w/g separately I know it comes with 3 springs; 5, 7 and 9spi.

 

Thats exactly what I was going to do. I am taking off my Bassani and running stock becuase thats what the flash is meant for. Ill make sure to bring it to a dyno after the flash to get the A/F numbers.

Now for the compression test to make sure I am good... anyone know of any nationwide known shops that do it for a good price?

 

Good to know, so I will be able to run it. Thank you!

 

yup Evolution WG and SFR is a dealer that can get you that spring. super easy to change out.

 

any insight on a compression test? I dont have the right tools to do it myself.

 

its actually not hard, you have get a kit from pep boys work around our retarded manifold

 

I boosted my car around 70k miles, no problems on 10k miles. first tranny too

 

How much boost are you running and what are you putting down?

 

hey man, i've been boosted for a lil over 10k mi.. no problems whatsoever. good power n reliability so far for me.

keep in mind tho... a 5psi really comes out as 7.5-8psi ...

 

what

 

definitely doable. I got the aps kit with external tial wastegates and got a 4lbs spring and hks evc6(overkill) and I got a 4,6,9 lbs setting. with bc off it runs 4lbs perfectly, thinks its a .3bar spring. don't know how running lower boost will affect the reflash however, u might run rich as hell and have jacked up timing, I got no idea how the reflash reacts(if it does) to different boost levels.

 

bump this thread for more insight... I have the money.. now im just scared..

 

Wow, this thread been while.
Still thinking about to go with TN kit??

 

Yea I have the cash but im scared to boost my DD..
