Whole new car on steroids. The car will be sooooo much better than before!

 

I would tell them to keep it under 400...we all know what happened to Brian's G at these power levels... either way you look at it your still in for a ride

 

All i know is i cant wait to drive it its going to be a blast

 

I told them to tune it safe they said they did it really conservative and it made 430 ish whp so ima trust that they know what a safe level is.

 

I hear you and I'm not questioning their intention to tune it conservatively at all, Tuan is a very good tuner. I just wouldn't risk it unless you have the cash ready to spend on a new block. Even from the horses mouth, APS themselves has posted on another site, that they never let their stock block APS TT Zs leave their facility with more than 360-380whp. I can tell you it will cost a lot more money if you blow your motor, instead of tuning it very conservatively and saving for forged pistons and rods. Around 380whp is still more than 150whp over stock! But if you've already excepted that and are financially prepared and ready for the downtime, then more power to you. Of course because of my experience and others that have blown their motor, my advice is more conservative. Either way, good luck with everything and you're car will be a beast!

 

^speaking from experience there..

I know that since the release of the kit, APS has revised down their recommended HP numbers to around 380.

 

We will see what happens if it blows up i guess that means i got to spend more money but i've seen lots of cars running in the 430 whp range with no problems. But i do agree with you about there there is a chance it will blow up but wen you turbo charge any N/A car, that wasnt designed for boost, theres a risk for that weather you tune it at 380 whp or 400 whp or what ever power up pick you run the chance of it blowing up so i guess its a gamble, im just hopeing for the best thanks for all your guys advice tho its appreciated.

 

Yes and there's obviously a general limit to what the the stock block will hold. I can only tell you what I would of done differently and if I would of known back then that APS themselves said to limit power to 380whp, I would of done it. Anyway, I'm not trying to worry you, but I just don't want any fellow Z/G members to go through all the hassles and extra costs for just a few more hp. Again, good luck with everything and you're in good hands with GRD.

 

definitely a gamble. Just watch your fluids, temps, etc and you will should have fun with it without too much worry. Personally, I would say 430 is a bit much for a stock motor, but I would also say, Tuan knows more than I do.

 

I think a lot of has to do with how you drive the car too. Tracking (anything other than 1/4mi passes) a stock motor plus turbo probably isn't a good idea if you're concerned with longevity. I know BriGuy beat the snot out of his car with the stock block and everything was fine...but who knows if/when it might have let go. There are also a lot of other people with 430whp stock that are fine...it's just a gamble. This other thread has some good info https://my350z.com/forum/forced-induction/273792-stock-motor-with-forced-induction-how-badly-did-you-push-it-6.html

 

As far as I know every tuner here tunes conservatively, but engines still let go whether you like it or not. I would rather enjoy my car for a longer period of time even if it means with a 40whp decrease. Like I said before ...either way you look at it you are in for a ride.

 

Exactly! if I could do it all over again, I'd enjoy it at around 380+whp, while planning and gathering funds for a future build. Then eventually build it and turn up the boost for 500+whp!

 

Well im leaveing this moring to go pick up the car I cant wait to drive will post up the dyno sheet later wen i get home Its going to be along ride there.

 

That's awesome! Congrats on going FI!

 

if i could do it all over again i would have waited until about now to buy my car (purchased in nov 2004, used 2003 touring). I would have looked for probably another 2003 touring for cheap and got a built motor + twins right away. oh well...

 

Yes. On APS's website, they only recommend 380whp now. And tuning has NOTHING to do with blowing (rod failure) a stock motor. Its the fact that the rods are so thin. Its th torque that will eventually kill some peoples rods. I say some, because there are defaintly consistancy issues amoung rods. Some hold, some done. Its a gamble!

Back to topic at hand. I love my APS kit to death. ive beaten it since day one, and its taken it like a champ. Zero issues, quality parts and design with massive power throughout the rev range.

 

Well, how is it??

 

Sorry i ddint let you guys know sooner but its great the first time i boosted it i was all smiles its like a whole new car. It runs great no problems what so ever. At first i didnt know about doing it bc it is alot of money but as soon as i drove it i knew it was worth it Will post the dyno graph soon.

 

Well i finally got around to scanning the Dyno Sheet it has the baseline dyno and after the APS TT kit on it. I also took a few pics of everything.
