LS3 Coyote

[ender2664]

I am looking for an engine right now and have seen alot of carbed motors that cost more than the LS3 and Coyote do...is it not a good idea to be running one of the newer FI motors in these cars?

You need to ask yourself whether youre building a Cobra replica or building a Corvette/Mustang in a Cobra body?

If you are building a Cobra 427 replica, there is only 1 engine choice, a Ford BB and the price of that engine is not cheap.

Good luck,

If I recall your previous posts, when you say 'Ford BB' you mean an FE, not a 385 (e.g. 429, 460) - correct?

Good plan. FWIW, build it for YOU and what you want, not what others expect or suggest. Some go for authenticity while others have higher priorities.

Ultimately it's your car and you're the one that has to live with it. Well, you and those inheriting your estate.

Just kidding.

Sort of.

I am 30, so if I die it will be in a firey Car reck in my cobra and my estate will have nothing to worry about
I want enough power to be able to out run all of the Porsches and bmws in my neighborhood but not so much that I cannot smash the throttle without worrying about sudden death. I was thinking that right around 400 will accomplish that.

When I see engine prices quoted and thrown around like this I often wonder if people have thought through the big picture.

Ie.
Does the EFI engine come with the computer, electronics, injectors etc..?
Has the cost of upgrading the fuel line, fuel pumps etc been factored?
Has the cost of the tune been factored?
Had the cost of installation been factored?

Compared with a carbed engine, it's apples and oranges...

Just a though, in case it was overlooked

[ender2664]

They were not overlooked.

I like the idea of a coyote setup. If you have grown up with fuel injected cars, linear throttle response, new age reliablity and you like good gas mileage this is probably the road to go down. I'm buying a used cobra and there isn't a ton of them with Coyote setups on the market. It is much easier for me to find one with a stroked SBF and carb setup. I love the sound of an old school motor thumping around so I'm willing to give it a try. My logic is if your not driving it every day and its a toy you can't go wrong buying a car with a carb setup. Buy a car that is already sorted and if its not for you then go to a modern FI engine setup. A properly setup Coyote car is probably as much fun or more fun than a SBF.....sure you wont have the sound but the driving characteristcs would be great. Of course this is all opinon of a guy that doesn't even own a cobra yet so take it with a grain of salt. I wouldn't be looking to buy a cobra to outrun the BMW's and Porsches in your neighborhood. A serious M3 or a 911 will run circles around your ass. Keep in mind these cars are practically a go-kart with a fiberglass body and you don't want to crash one of these things. Good luck , think smart and enjoy your path to potential cobra ownership

Depends on what you're planning to do with it. You plan for a fun street car with about 400hp. That's not a very tall order. You don't need to spend cubic dollars to obtain that. A standard crate motor from just about anywhere will accomplish that within a reasonable budget.

If you're planning on racing, though, that's a different story. If you want a solid reliable engine that you can beat on season after season, you need to spend cubic dollars. Speed costs money.........

If a Coyote will float your boat and you will not want more, then it is very cost effective. It is a good solid engine. However it is not the easiest engine to modify to make more power. Variable cam timing, over head cams are difficult engines to work on. Pulling the heads off and porting them would be quite a challenge. I doubt there are aftermarket performance heads available yet or cams for that matter. I could be wrong. But my point is this would not be an easy engine to make more power normally aspirated.

The easiest way to make more power would be to force air into it - blower, compressor, turbo. I would expect that has been done already. Typically 30-50% more power is within reach relatively easy.

Many people decide they want more power after a few seasons of getting used to the car, and learning how to handle such a beast. Now if forced induction is something you might consider, then the Coyote is still a good choice. If not, then you better be certain you will not want more power later.

Now if you think there is any possibility you might want more power later, when you are putting in the fuel pump and fuel lines (the entire fuel delivery system), size it big enough to handle the most power you will ever want. Then you will not have to upgrade and spend that money twice.

An LS3 has just about infinite options these days. You can buy a crate 430hp or a crate 525hp engine. GMPP makes a factory oem computer and wiring harness that fits the engine hp. You can also easily buy the accessory set-up depending what you want as far as p/s or even a/c. If you only want the alternator, they make that one also.

If you go on CrateEngineDepot.com they have complete kits with engine, trans, and computer to drop right in. If you want more hp later, there are about 500 more ways to get an extra 100hp pretty cheap.

Oh..and witht he engine being all aluminum, they are pretty light weight and compact.

Currently you can produce about 500 hp from a Coyote with headers, ram air and a tune.

look to add a supercharger to produce more HP coyote makes a SC crate engine with 9.5 compression We are using the 11.1 compression so you can adjust the boost down and tame it... or you can boost as seen below.

FYI you can always start with the 11.1 motor and add supercharger later (which is what i plan to do with my build now) tremec 600 3.64 gears or you can go with 3.91

BTW Porsche and BMW really dont stand a chance with proper tires and surface

FYI I currently have a Corvette suspension 406 Chevy motor Cobra..... and everyone jokes about the distributor in the wrong place... so original!!!!!

Jay could answer a lot of your Coyote questions. or simply search the internet.... it is full of answers youre looking for.

[PLDRIVE]

Ender2664,

You have made several posts dealing with basically the same question.....
What engine to choose?????

Excuse me if i missed your answers, but what's your budget for an engine?
Do u really care about fuel mileage??
What sound are u looking for? Do u want or care for a lumpy idle? This is a big deal to most cobras guys.
Carb Or EFI? A Good carburetor (Quick Fuel, Pro Systems) will equal or out perform an EFI in regards to power assuming u have it dialed in.
Big block or Small Block FE= Original but costly, other BBFs would work but probably overkill for your goals. SBF Windsor is cheaper to build and makes excellent power. Coyote has a different sound and not a lot of low end TQ, however it loves to rev.

My Preliminary thoughts on an engine choice:

A stroked 351 Windsor is your biggest bang for your buck. A 408CI Windsor or larger would accomplish what I believe to be is your objective. A Big inch SBF Windsor will make more TQ and more horsepower then a Coyote. I would go with aluminum heads, HYD roller and a factory block (can go up to 434CI). For your HP goals there is no need for an aftermarket block. Build the engine above your HP goals (I promise u will wish u did).

Take the time and call a few reputable engine builders. You will be money ahead if U buy a custom built engine over a FORD crate engine.
The following company’s stand behind their work, and will meet or exceed your expectations.

Jim Kuntz = Kuntz engines
Brent Lykins= Lykins motorsports
Keith Craft = Keith Craft Performance Engines

1-what's your budget for an engine?- Under 7k
2-Do u really care about fuel mileage??- Some what
3-What sound are u looking for?- not a big deal to me
Big block or Small Block?- small
Thank you for asking questions to figure out the best engine choice for me, i really appreciate your help.
