Agreed! It looks like a lowered Nismo with an exhaust and intakes.
If it was my car, I'd skip the pillar gauges because I think they add a hint of "rice" to what is a phenomenal, beautiful car that doesn't announce it's been tuned until it's GONE!

Hmmm... new patio and hot tub or GTM TT? :yum:

Depends on your goals. If your just staying with what the base kit offers "no" you dont have to have it. However, It is an option that most and even my self would urge you to get. A boost controller must be met with constraint! Just because you have one doesnt mean you need to turn the boost up!

For instance Sam@GTM and I are building the 1st 1000+hp 370z right now. I for the love will NOT be running that high of a HP and Boost on the street unless I cross a Bugatti Veyron in which I will proceed to hand him his @SS!!! lol.

My Buddy is going to come over and help me out on the weekend to get me started and provide direction if I have any questions and after work he is going to shoot over. As for getting old I don't think thats the problem with not being able to stick lol. I think others between this forum and my350z were having this issue also with all stock. I don't know maybe I made that up lol. The last concern I have is just my warranty. I understand that I pretty much tossed that out the window on the engine and drive train, just if my headlights don't work I don't want the dealership to be like Ohh yea they don't work because of the TT kit you installed so warranty wont cover it lol.
Frank

PS fuz since I seen you reply on this, off topic I am in the market for a altima coupe new(hint hint). I spent my money to play now she want to play also, can't blame her lol

I think you're ok there. *haha* Magnusson-Moss Act keeps vehicle manufacturers honest in that regard. :)

I would certainly go with an electronic boost controller of some sort. Especially with the internal wastegates. Great insurance to have. I went with the HKC EVC 6 and mounted it where the dummy switch cover was in front of the cup holder. I have zero switches there since the NISMO comes stripped and not equiped from Nissan. *haha*

I actually thought of doing this. But, again, my build was budget conscious and I didn't want to go through the extra expenditure of custom work placing the new gauges. The most obvious place would have been in the dash as OEM gauge replacements, but I prefer the OEM gauges are left untouched. A custom console/cubby placement could have been an option, but I use my cubby as the Z has otherwise no storage - and, again, I didn't want to get into custom costs. The cups are much less obtrusive than an A-Pillar pod, so the gauges are cleaner and less noticeable. Even from outside of the car.

Storm or bullitt do you have another option to where I can put it at. I am going to probably get the one that storm has in his car but i can't mount it where his is because I have the the touring model so there are two switches there for my seat heat lol. Guys thanks alot i must say that you have made something I really wanted to do a reality for me and for ever gracious. If you are ever in the virginia area my door and a hot meal will always be open to you

tao168 05-30-2010 05:15 PM

Just wondering you guys install a turbo timer? If so how was the wiring done. Looking at installing 1 but been working at the wiring for sometime.now

Hmmm...I understand now. I didn't know you had the Touring. Ok, so if I had actual switches there and didn't want to give up my cubby, I would probably mount the EVC 6 in the headliner just behind the dome lights. And thank you for your gracious offer of opening your home and offer of a meal. A lot of people won't understand what a kind offer that is, but I do. Thank you.

No turbo timer for me. Water cooled turbos do not really call for one. Though, just out of habit I do sit and idle for a minute or so before shutting down if I have banged on the car just before coming to a stop.

Yeah gd habit maybe I should start that, na but because it talks me only 10min to get to work don't even think the engine is warm by the time .I stop lol

bullitt5897 05-30-2010 08:43 PM

Like stormcrow said put it behind the dome light like me... I had mine custom mounted in my head liner. A few other places to install your boost controller or turbo timer would be the glove box, center console and/or center cubby if you don't have nav. ;)

Do you happen to have a pic. I see that as being an option since I do have the navi

Hey Sam, I was wondering if these cars are still capable of passing the OBDII scanner for emission tests.

I know that Hondata provides a setting in their tuning program to turn on "OBDII Readiness" to pass emissions even with out the catalytic converters.



Any answers?

All OBD2 functionality are maintained. The Service engine soon light will come on when ever there is a problem, and the car will go though OBD inspection .

Sam

Dr. JD 06-01-2010 02:04 AM

Thank you Sam, just wanted to make sure it would pass inspection.

I love how he is always watching these forums to provide assistance and direction. I am glade that I purchased all my products from this company.

sry didn't mean to go off topic forgive me storm, you can have your thread back lol.

Damn you for all of that OT, Frank. :gtfo2: *lol* I kid, I kid.

FuszNissan 06-01-2010 09:02 PM

LOL..I have an EVC and haven't touched it. In fact I don't even know how to work it. I just figured don't touch anything and let it run...lol

Kastley85891 06-01-2010 09:31 PM

Lou - very wise where boost is concerned.
GTM - does the EVC have a boost limit cut off ? obviously the reflash will not have a boost cut of any sort so wondering what safety net there is , if any, some one could theoretically grenade a motor very easily if un wise, unlike Lou.
Does UPREV have any pressure sensing fuel cut or simular, over MAF V, anything?

I actually recalibrated everything within mine just for giggles. Read the manual. It's a bit complicated, but it's not too bad. There are some really good settings to be found in there as the EVC6 does a boat load. Also, you may want to double check and make sure that some of these settings are not at defaults. Not mentioning any names, but a few clients of other shops have found their EVC6 set to 4 cylinder mode on their 6 cylinder cars. :)

Actually, it does. Not only does it have a cut off, but it will drop the boost, immediately, to a preset psi. I have mine set at a maximum of 10 psi and if that level is reached it immediately drops it to 7 psi. This controller is loaded.

FuszNissan 06-02-2010 11:22 AM

Yeah, it's a crazy controller.

Thanks Stormcrow, good to know, seems a very nice EBC

One more if I may, does it have per gear settings? in rpm set points or is it just a one shot target and upper liit setting?

It's just a single target PSI. The gear that you are in at the time is inconsequential to the EVC. The same goes with the RPMs.

Kastley85891 06-02-2010 04:13 PM

Do you have any idea what your injector duty cycle is with your current setting/tune?

Sorry , I did not see your injector size, are you on 600/650cc or bigger? also single pump upgrade?

I think you know where I am going with this...

600cc DW injectors. Single Walbro 255 in-tank pump. Roughly 80% duty cycle on the 8.6psi map. Plenty of room for growth.

Kastley85891 06-02-2010 04:34 PM

80% gives a nice margin.
850cc's needed for the project I would like ;-0 thanks for info.
One day I will be set for my own TT and experimentation once again begins, but for now its the bone stock ride and 'Wife set zero mod fund' as 'punishment' for my previous cash excursions....

toner123 06-06-2010 10:13 PM

Hey storm do you know what dyno sam used on your car. I know it was the dynojet but from there website he has two models, the 248 and the 224. Just wondering because I know dyno's can vary and I wanna try to find the model you used, so I know that I am around the same rwhp as you since we have the same goal. Thanks

Sam can correct me if I'm wrong, but I believe they use the 248 (Rear) drum for RWD\FWD vehicles and the 224 (Front) is used for AWD.

Damn fine question, Frank. I have never asked Sam, but will do so and let you know if he doesn't respond to this thread before then.

Not yet. Waiting on SPL to release a set. I sure hope they do...and soon.

I am going to need a set in a few weeks lol the wheel colors got finalized woot woot

Well I am glade that you find it a good question. I did some research before i posted that and there are so many reviews of others contradicting what others say. One person states that the 224 and 248 will give same results. One person replies calling him a idiot and says the 224 will give a higher rwhp then the 248 because the drum is lighter, blah blah blah. With all the dynos out how the hell do we really know what are rwhp is. dyno dynamics reads an average of 10-15% lower then a dyno jet. So who's number are real lol. There has to be a standard set here or I am going to develop a dyno that will say you have 600 rwhp after all you did is install intakes. I hope I am making my point clear in what I just wrote. All the BS just makes it that more confusing in what dyno you wanna run on. If I went to run on a dyno dynamics hen the rwhp should some what equal the same that I would get off of a dyno jet
Frank

bullitt5897 06-08-2010 08:45 AM

Dyno dynamics and dynojet both measure resistance load differently hence why they give different numbers. You got to remember people have seen numbers to vary on the same dyno just by how tight they strap down the subject car... I agree there needs to be a set standard that we follow by. Maybe we should start a thread about this and have the vendors chime in on what they use and why they chose that style or model...

Great Topic Frank!

p.s. you let me know when your dyno comes out!!! I want to put my car on that! shoot if I am going to be making power in the 1xxx+ range on a regular dyno lmao yours would be like 2xxx+ hahahahaha

FuszNissan 06-08-2010 09:34 AM

Where's your car at Bullitt, I must see some build pics.

bullitt5897 06-08-2010 10:24 AM

Sam will be posting my thread in the next few day hopefully. it is sure to be one of the most Technical and in depth threads on the370z. I talked with him about it last night. The thread will discuss a lot of the details of my build in depth and the reasoning behind the technology used. We have been waiting on the build to get to a certain stage before posting up my thread. Also, it is taking Sam some time to put together his in depth documentation on the build. Lets just say this project is for sure ground breaking in the history of the 370z and VVEL technology. so stay tuned my brothers we have a wild ride ahead of us!!! :tup:

Frank

Frank, I gave up long ago chasing a number. In truth, the dyno operator can make the dyno say whatever he wants it to say. I would go with a reputable tuner and then take it to another dyno for a cross comparison and call it a day. If there is not a huge discrepancy in numbers, I wouldn't pursue it further. I would go as far as to say that even a 20-30whp difference on the same type of dyno would be sufficient for me not to balk. Granted if one shows 50-60whp different and they are not load based vs inertia (mustang/dyno dynamics vs. DJ) then I might dig further. Someone's inflating the numbers in that instance.
