GT-CORDY

I have a 03 Mustang GT that I can't make my mind up on which one to turbo. I would like to keep the cost down as much as possible but still have a reliable 9sec or 8.9 best case senario. Not a everyday driver just weekend car. My ideas are 370 with stock crank, good rods and pistons ect, ported 317 heads with a th400. Bulit 408 with good heads ect. Or finally a Coyote with good rods and pistons, stock heads and cam. Looking at a pt8847 turbo or billet 76. The thing that scares me about the lsx is the wiring, I want everything to work like factory. I know this has been covered a thousand times but I would like help on MY setup. Thanks guys

Being that this is an ls site pretty sure that most will say go ls. If your trying to keep cost down then a boosted build is not the way to go unless you do a junkyard truck engine. If you cam afford it go built 408 and boost it.

Pick up an Lq9 or Lq4 and throw a turbo on it. When that breaks downt he road put forged internals in it and let it eat.

Is there really a big difference in a 408 vs 370 when boosted? It's a fun street/track every now and then. This would be my first lsx so I want to make sure I have a decent parts list. And how would a pt8847 spool on a 370 for anyone that has that combo.

Grab a low budget setup to learn on. Once you get it sorted out than get some forged rods and pistons in a 5.3 or 6.0. I love the new coyote engine but there is nothing budget involved with one of them.

Reliability? Coyote? Really?

Go 5.3, for budget racing you're not gonna beat it.

I'm only swapping an ls because I can't afford the coyote. I want the same power levels, but a lot less cash.

I will keep my eye out for a pullout lq4 and like you guys said I can upgrade as I feel it's needed. I just hope I can figure out the wiring part of it. Thanks guys

You want a sub 9 second car and to have everything work like "factory"???

GT-CORDY

Yes pop n wood I want my lights to work with the switch, horn, ac and so on. Not a hard concept to grasp but not sure on your sarcasm either but yes it's not a race car but a fast street/track car.

I'll admit I have never built a sub 9 second car, but from what I have seen by the time a car gets into the 8's it is more race car than factory street machine.

You probably know this but it takes way more than just horsepower to get there. Building an 8 second car is something very few people can accomplish. Doing it with a full interior and working AC is even more impressive.

Now I don't know you, maybe you're Grumpy Jenkins reincarnated. Sorry if I offended you. But you have to admit from your initial post you come off pretty clueless. If all you want is your horn, lights and AC to work then even I can do that. Hell, I have done that. Like you said the info has been posted a thousand times.

But building a "reliable 8.9 sec car that works like factory", AND on a budget. All I can say is maybe you had better temper your expectations a bit.

Yeah, 8 secs is setting your goals too high.

There are notchbacks on here with built motors running 9's, but they are mid to high 9s in street trim.

If you are at the mercy of a budget, get a junkyard 5.3/6.0 and turbo it like you said. Spend the money where it counts and don''t short-cut the important stuff. That alone will get you the most reliability out of the setup.

Set your goal for low 10's/high 9's and go from there.

Keeping the AC on a turbo car is hard to do. If you want AC just put the windows down and go fast. For a budget build, get a pull out 5.3 truck motor put a nice cam and set of heads on it, and turbo it and 9's should not be that hard.

Gets into the pick two, fast, cheap, or reliable.
