:icon18:still got some minor issues that need to be twaked out before i make a decision

I would stop by his shop and find out but sams get tired of me visiting!

just do the drive by and peek in through the shop doors.

Thinking about this kit, too. Really need to see some results.

well there were the results from my install. 6 psi 390 hp with 350 tq. i stopped short of the 8 psi as i have AT and want a VB upgrade and a new tq converter

great results, but kinda skeptical about it. Its like one of those things your not sure about. Im nuts

Yeah i read through your thread. I'm very curious to see what a manual car does on 8lbs, though.

Hoping for at least 420 with HFCs & CBE.

hell ya 420 will be easy. MY 7AT would be seeing 420 at 8 PSI

You don't necessarily need a restalled torque converter, but you should invest in a heavy duty ATF cooler.

VB? :confused:

Valve Body upgrade. Typically consists better solinoids that allow for faster shifts. One of the big reasons for this is when the auto shifts close readline, if you add a bunch of power, you can bang on the rev limiter, causing a performance loss and the fact that faster shifts are supposedly better for a transmission, all other things being equal.

Ohhhh..... duh :facepalm:

I don't think he needs that either. The 7AT shifts very fast as it is, and has full lock up in each gear. I highly doubt you're going to be able to get the line pressure up much faster.

As to hitting redline, tune the fuel cut a few 100 RPM's higher and shift a wee bit earlier -- he'll probably have to do that anyway even if he can get the line pressure up a little faster.

Honestly, I wouldn't even mess with any of the major trans parts like valve body or torque converter given that our trans is a very different beast than your typical slushbox.

I think just a bigger ATF cooler will be fine. Heat is the major killer, so that is really all that needs to be controlled.

i have a tranny cooler installed and will be doing a full tranny flush every 30000km

I'd say you'll probably be fine then.

On your next flush, see how the fluid looks; if clean, go for 400+.

Anyone know the max a stock 350Z AT is holding? I can't imagine Nissan would have built this one less sturdy.

The 7AT is a bit better than the 5AT but this was a problem almost every 350Z Auto owner faced when going FI. Retuning the shift points and adding a VB upgrade was the solution 99% of the time. One easy way to avoid the shift issue is to figure out where you need to manually paddle shift to take into account the slight lag (about 500 milliseconds). The valve body upgrade is actually pretty simple, you just dropped the valve body and either did a swap or sent your's in to be modded. Usually cost about $1k. They do recommend a tranny cooler as well because the upgraded VB tends to make the tranny run hotter.

SUB scribed!!!

Hmm. Well, it will be interesting to see if it makes a difference for the 7AT too... I think some of the shift speed must be tunable as is, given that it definitely shifts harder and faster when you use the paddles.

Does the ECU throw a code if line pressure builds faster than expected?

How much power was the 5AT holding before something broke?

well the 7AT is the same that is used in the 420 crank hp M56 so i think it could handel 420WHP however i was not about to test this on a 2300 mile drive back to canada when i had to get back ASAP for work.

I must say that I agree with the decision you made on that. I watched your thread closely and I was impressed with the results you recieved.

Thanks toner. If i lived closer to GTM or had a shop close i trusted and did not need to make a 2300 mile trip in 24.5 hr i might have gone bigger boost. i still will it will just be furither down the road.

I say drive that car now the way it is. Enjoy it(which I know you are lol) and see how everything holds. Some people wont be happy till someones car is pushed to the limits and then it goes boom lol. I don't remember what your goals were as for hp but if you are already in that window screw it and leave it alone. No point in racing street light to street light because the only thing that loses is your wallet. You have a hell of nice car thats S/C, that was installed by IMO the best damn shop in the bussiness.
Frank

results? been over a month now...anyone, bueller?

seriously, WTF?

Does GTM not want to sell any kits?

I smell technical difficulties

Ive tried calling and sending a pm no answer.

Sorry for the lack of updates, just been busy with a million thing. As for this project the time that it is taking has been anticipated and it is not surprising, couple kit has been sent out and we are getting the feedback needed to make sure our instruction are 200 % simple and easy to fallow. We should be on the dyno by Saturday and will have tons of pics to share, also we will be posting a link to our instruction manual for anyone interested in tackling this type of project .

The feed back that we are getting back form the people that saw the instruction (customers and installer ) has been extremely positive so the tremendous effort we are putting into this is paying off .

Stay tuned and thank you for your patience.

Sam

Great news! cant wait to see that SC on the dyno.

Sam is really busy guys! just look at when he posts... its always early in the AM like 1am his time and 4-5am eastern time. Props Sam :tup: wish I was at the shop to help out I know you guys have a TON of Cars in right now and mine is a beast of a project!!!

Cool, in for results on saturday!

Me too, can't wait. :tiphat:

i smell stillen fanboy trying to thread crap... :gtfo2: ....

Or, someone who is stating the obvious..

Fellas Fellas, refrain from making assumptions until tomorrow rolls around.

tomorrow is here, lol

tomorrow was yesterday... sounds like another car with a "boost leak"..

lol looks like GTM is justy delivering what they promised unlike others around here

wheww, thanks for the info...probably to much power.

...For a min there I thought they had to re-think their kit with alt components and a new tune...

Well it looks like i'll end up going with Stillen. I don't like companies that beat around the bush and can't take 30 seconds to make a forum post to keep people in the loop. I've dealt with that too much in the past.

The aftermarket for these cars is starting to feel like something of a joke. :shakes head:

what did somone else have to do that? :stirthepot:

But Im sure both kits will be pretty good after they have been on a few cars and they can get a better understanding of their kits from being on multiple cars. I dont think any kit has been perfect in its first year of conception. Im still partial to GTM and all with their FMIC and slightly better numbers.

Really the more they are on here the less they can do their job (both companies), which isnt being on the web typing messages. Just cuz they dont answer every question right away on here doesnt mean they arent responsible or sensitive to our needs. We cant be too spoiled by the forum.

Take five minutes and give them a call, forums are not usually priority when they are trying to work on cars.

really they are trying to develope, refine and install kits and we are just here typing on a forum. Who has more time on their hands? A phone call by us is too simple.
