Default Forged & Turbo Daily Driver

So, Iím planning on getting a Ď15 SS Sedan late this year and Iím wanting to do a single turbo kit from Kozaa with a 76/75mm Precision Turbo, forge the motor ( pistons & rods ), cam from either TPS or Vengeace racing, E85/93 ( no meth ), port the stock heads, tune, and I think that would be it.

My question is, how would the car fair with daily driving and road trips? I hear forged motors use more oil and knock when they are cold. If I could forge the motor and have it drive like normal until I get into the throttle that would be amazing!

I daily drove my forged 383 turbo TA and had no issues. Why do you want to forge the motor? What power are you looking for?

Iíd like 600-800+. 600 on low boost settings & 800+ on high Boost settings. Iíd also like to not break a rod while pushing it.

That SS comes with an LS3 right? You should be ok with a stock motor if so.

Yep, it comes with a LS3. Iíd still like to stay on the safe side and just put forged pistons & rods

I had a 76/75 on my G8, worked fine and spooled quick but the T4 choked up the engine a good bit at higher boost levels. I wouldn't bother forging a Gen4 engine for an 800 hp turbo setup, with a good tune and proper fuel the only one that will blow it up is your tuner. I also wouldn't bother porting the heads, LS3 flow good enough to make a lot more power then your planning.

If you feel compelled to forge the engine then get a bigger turbo to make the cost worth it.

So, at what power level would you forge the motor? I honestly liked to figure out the right sized turbo so it wouldnít take forever for it to get boost.

good info here, no need to build an ls3 for 600-800whp. turbo cam, good fuel system, e85 and good safe tune. mine has been turbo for 3 and a half years

You will get sick of the horrendous gas mileage and will soon give the daily idea up, and this will happen long before you hurt your motor.

Ah, okay. So. Basically I can keep my AC & have all my creature comforts while making 600-800 horses while driving 100-500 miles? That would be amazing.

Absolutely, as long as kit is well designed and all heat from the kit is well managed. My car drives like stock out of boost and not sure what that guy is talking about gas mileage... under cruise should be close to stock like as well, as long as you tuner has any clue what he's doing

20MPG is bad? Assuming he has a manual... if he has a 6L80 then the turbo gonna blow that up anyway lol

No point in e85 for 600hp and daily driving, I don't even think of E85 until over 750hp just doesn't seem worth the hassle to me.

I didn't bend a rod until I ran 30+ PSI from a T6 billet borg, and even then it took awhile. With a 6.2 it wont take many turbos long to get into boost.

Before I say what I'm thinking, let me make sure of something first. Are you saying there's no difference in fuel mileage between E85 and regular fuel?

Everyone know there is a difference between pump and e85 gas mileage, where did I say there is not?

21 mpg isnít bad for 800 horses.

You basically called me a lie, but whatever. You're right, I have no clue what I'm talking about.

He said he wanted to run 93/e85 and a flex fuel sensor is dirt cheap for these vehicles where you can run pump day to day if you're worried about gas mileage and then fill with e85 when you want to run high boost.

Thats what I was going to do. E85 during high boost.
