Best engine to drop into a GT
 

So in you guys opinions, whats the best engine to drop into a 2006 Mustang GT body. Trans is auto.

Would like to see 400-500 hp, for between 5-10 grand.

I know I can add onto the stock with FI. I would like to look into either improving the stock engine, or replacing it, then adding FI. Goal for the car is about 700 HP.

Would love a BOSS, but just because I love the old boss engines, I read the new ones arnt true boss engines, wrong heads. I guess I could pick up a block and add appropriate heads.

Thoughts, comments links all appreciated :D

there are several guys that have built motors capacble of 700HP 10K might be a little low to do it properly though

Sounds like a solid starting point.

I wasnt expecting to get more than 500 hp out of the base engine, but would like an engine that wont blow up if I put 800 to it via FI of some sort, down the road.

Any idea what kinda hp that kit is lookin at?

You have to decide if you want to spend more money getting a new engine vs building up the stock one first

Without spending more than the $10k you listed, I doubt you will hit the 500rwhp without going FI on the stock block... Perhaps with every bolt-on and a new rotating assembly... I only say that because you stated that you didn't want to grenade the engine if you decide to hit"800 to it via FI of some sort, down the road"... I read that as you were hoping for 500 without FI...

However, you could probably spend that much (probably more) on a GT500 5.4L motor and trans from a wrecked donor car and get near there... But at that point might be better to just trade yours in and spend that on a true GT500...

Don

ooh no way you are getting 500 NA

i took it to mean you wanted to get a new engine and a blower with 500ish now but have it capable of handling 700 in the future

with the engine alone, you will be short of 400 rwhp.
add FI and you can hit that 700.
friend of mine has the livernois 298, stage 3 heads and cams, whipple 2.3 @ 14 psi on pump gas, getting about 640 rwhp.
a NA build i can remember has a stroker, stage 2 heads and cams and about 380 rwhp.

I see, yeah I figured 500 rwhp with just the engine would be a lofty goal.

I dont mind tankin the stock engine, that is actually what I was thinking about.

I was hopin to find advice on an engine that puts out somewhere around 400-500 hp, for somewhere under 10 grand, and would stand up too force induction to get too 700ish, and fit comfortably inside my gt.

From what I have read the stock block can handle up to about 800 (the block its self) but would need a complete internal overhaul. After a massive overhaul your prolly better off going with a crate engine, or building your own engine, correct me if I am wrong there.

unless you are going to do the work yourself, i would go with a built short block, heads and cams.
at 700 rwhp you will have to look at trannies and other driveline upgrades, as well as other odds and ends.
that friend of mine spent around $10k on only engine parts.
when going for 700 hp, it'll be expensive.

Well as my engine builder told me you have to come up with a plan before you order the first part.

You need to first completly figure out if you want FI or NA. Reasoning being is a build NA motor is not good for FI. There are things that are done different internally if you are building a motor for boost.

With that being said if you have any desire for a blower than build or have a motor built for that otherwise you are never going to be happy with the NA motor.

If I were you I'd take a regular 281 and have it built for by a good builder. They will lay out everything that needs to be done for what you are trying to achieve.

I doubt any of that can be done for around 10k, I have that invested now with no built bottom end just with the blower and other stuff to support it.

Hopefully if your are building a motor with over 600hp it's mainly for the track because over 600 on the street is pretty useless because at some point around there traction becomes a major problem on street tires and roads.
