Stock motor with forced induction . . . how badly did you push it?

Sounds like a bitter/sweet situation. Sorry to hear about the failure but I guess it is also a testament to the VQ to put up with that in stock form for
12K miles and...now you have a great excuse to build the motor! I remember emailing you on youtube after seeing your video, that car hauled butt! I too have the Turbonetics system with Meth injection and just turned 15K miles since the install. I have a more modest tune at around 350WHP and drive it like a grandpa with limited thrashings. Not a day of trouble (knock knock knock!!!) and I have driven it literally coast to coast twice along with 60 mile round trips to work every day. Nobody can argue with me about the reliability of this system on a modest tune. I am a big fan of Turbonetics. Good luck on the build, I look forward to seeing the results.

I am looking at a few different options. I may go with a built short block and keep the ST and add meth and NO2. I may go with twins. Not sure yet.
I have also been talking to my buddy that owns a local performance shop here in town about doing a 2JZ ST swap. I think that would be wild as hell in a sedan. 2JZswap.com has there kit on the market now for $2,200.00 for the 350. I have not talked to them yet about if it will work on the G Sedan.

I had a few question for the people that fit the category mentioned in my title. First off, how long do you plan on having the car, is it for a couple years or just for short while? I have the facts or Forced induction for noobs on the other website and understand that there is a certain point in which stock internals can hold power for but my main question is reliability. I really want to get a single turbo kit for my car and will tune it but a lot of people have said this makes the motor not last as long and die faster. Others say it depends on how much boost you are runnng etc. My ideal boost would be from 8lb to 9lb and my goal would be around 370-380whp so nothing too crazy. I plan to have the car for the next 5 years or so. Input is appreciated as i need to know what i can do.
thanks
thanks

I recommend you make a new thread for this but all in all you need to install everything you need that will make the system reliable. E.g. fuel return, aftermarket ECU with boost cut and knock sensor, injectors, and most importantly you need a good, conservative tune from a respected tuner. Many will argue you can reach your goals without some of this stuff, but I can almost guarantee your engine won't last as long. All it takes is one boost spike and/or not enough fuel in the mix and BOOM you're done.

I have the Turbonetics system on my 06' 6MT. I have stock internals, stock exhaust, a re-flashed stock ECU (just haven't had the time to get to anything else). I do have a Snow Performance Meth. injection system for a little insurance. I will say this...
I drive the car every single day. I have driven it cross country twice since the install and have put nearly 25,000 miles on it since having it installed just one year ago. It performs flawlessly. I have not had a single reliability problem with the car in this time. I will also add that I do not drive like a teenager but I do get into the boost to some degree every day I drive it. I am running 8.8 lbs of boost and I think the meth. injection is worth the spend for the added piece of mind. I would not reliability issues scare you away from doing this if you drive responsibly for the most part and don't feel the need to wring it out every time you drive it.

My G has been boosted with a Vortech SC for over 38k miles on STOCK INTERNALS, STOCK INJECTORS, STOCK FUEL PUMP. No meth injection, no water injection, no NOS, nothing else other than a conservative tune.
I make about 360hp to the wheels with lower torque numbers due to the linear boost of the SC ... but the max boost measurement at the plenum is actually under 6psi due to the plenum spacer and free flowing exhaust.
My setup has seen numerous track days with hours of WOT stretches and upshift/downshifting. The biggest safety device that I use when tracking my G? High octane unleaded racing fuel (usually around 106 octane). This protects from detonation and keeps the cylinders cool during the constant high RPM WOT runs.
In my opinion the immediate torque and high boost at low RPM's from a turbo setup has a greater effect on reliability. I say this because when some turbo setups hit full boost well before 3000 RPM's, the engine is not breathing to it's fullest capacity which means the internals are under full pressure for longer periods before the exhaust cycle.
Again, this is just my opinion but I have seen it happen too many times that a turbo engine fails at lower RPM's ... blame the wastegate maybe or the tuner?
Just remember, the stock VQ is 10.5:1 compression and then add boost?? The R35 GTR has "only" a 9.0:1 compression with stock twins.
Just my 2 pennies...
