She's slowly dying in front of my eyes. ( My Turbo Mustang GT)

[dirtybird91]

Well guys,
Damon told me it would happen sooner or later, but I guess my twin-turbocharged Mustang GT is about to blow.:(
Smoke signal are telling me so.:o
I doubt I have many miles left until B O O M!!!

What should I do: Rebuild this engine or go with a crate engine?
I will need a crank, rods, and pistons if I decide to rebuild.
A Crate motor (short block) built for boost is $3,500.00 from some vendors i read up on.
Which will be cheaper?:confused:

Sorry, I haven't followed the car at all. What kind of block is it, and the ones you are considering based on, factory or aftermarket?

[DamonSlowpokeBaumann]

I know someone selling a killer shortblock brand new.....If you need let me know!..

[DamonSlowpokeBaumann]

Frank PM me I will giv eyou details..a PERFECT showrtblcok for your car in MD..Can maybe even pick it up

[darkstar_one]

FOXBODY OR late model stang?

[DamonSlowpokeBaumann]

Its a 4.6 motor new edge stang

Where have you guys been. After HP made him waste his time w/ the custom turbo setup for his SC he got a deal on a twin turbo kit for his 4.6L PI Mustang GT. He's had pics of the car on here before.

Anyhow. I'd go with a built short block and just swap it in, maybe get some patriot stage 2 heads and some xe272 cams.

[darkstar_one]

i say you just do the DOHC conversion and get more power of it, since ur gonna be spending so much dinero on heads.... thats what i would do, a nice 5.4 DOHC sitting in my SC would be so frigging shweet... but good luck dude.

Oh, that's right, I forgot. I was thinking he was talking about a Fox car.

Anyway, since the block isn't an issue here I'd probably go ahead and buy a forged kit and have a trusted local shop assemble. A friend bought a short block from CHP which proved to insufficient piston to bore clearance. It was a forged 5.1 and IIC the clearance was .015 which matched what the build sheet said. The pistons used stated that they required a minimum of .02. CHP used every excuse they could think of and my friend ended having to do a charge-back.

My point isn't so much that CHP was bad to deal with for support, though they certainly were, but more that this can happen with a shop that has no local reputation to defend. IMO much better to deal with a reputable local shop.

Also, another tidbit that car taught us was not to set 4.6 heads down on the combustion face. They'll bend a valve and you won't figure it out until you start it. Doh!

You can go pretty far with stock heads and PI cams. I always reccomend a god builder that is used to BUILDING 4.6's. I personally just had a 4.6 done for my supercharged Tbird that has a cobra steel crank Manley H beam rods and forged Pistons (ARP throughout..EVen main studs...I could have gone with a girdle and misc other things but the fact remains I wont even make over 400rwhp..(M90)

When frank finally reads this......ANyway I know someone selling a top of the line DSS motor. They know how to build 4.6's....And I can get him a GREAT deal on a SB someone didnt get to use because he ended up getting a cobra...

So Frank where are ya?

You don't fool around do you.

HEHE!!! Sorry Damon! I was feeling sort of pissy last night after I got home and parked that car. It was smoking from the exhaust a little and I know the end is near.:o I decided since my wife and I had the weekend alone with no kids that I would drown my sorry in some Jimmy Beam.:p
I just woke up from last night carnage and I am ready to think of a solution. I need to go the cheapest, but smartest route.
1.) You say your freind has a smallblock for sale.:eek:
2.) You also have a connection with a DDS motor! :eek:
A PM is closing in on you with great allacrity!!!!!:D
Also I think I was more interested in your idea to rebuild the rotating assembly with ARP and such.

The car is completely stock except for an HP Performance turbo kit and suspention components.:cool:
The setup I am considering will be built to handle a ton of boost!:)

[David Neibert]

Frank,

How much boost were you running ? Did you do anything with the fuel system or the ignition timing ?

David

[dirtybird91]

Exactly!:D

[dirtybird91]

Frank,

David

David,
I am running 8-9 pds of boost. The wastegates are set to open at that point.
I have done nothing else to the fuel system besides the #42 injectors, the SVT Focus fuel pump, and the Diablo chip supplied by HP.
Frank:)

[dirtybird91]

My friends over at www.fullthrottleforums.com (A local site for car enthusiasts in my area) seem to think I may be "jumping the gun since the car has not been tuned. The feeling is that I am running rich since the car idles at 2K. Until I can afford to get the car tuned I am just "pissing in the wind".:o

[DamonSlowpokeBaumann]

You don't fool around do you.

You know how it is..ALl depends on who you think god is ..

Anyway the 4.6 is a nice non piston slapping motor..With that comes these god awful pistons that cant handle boost very well...even at 6psi you can easily break a piston...

PM for you Frank

[JustinH]

The rods are actually the major weakpoint.

Forged rods with low compression pistons and a proper tune (SCT) would go a long way.

Amen to that!:cool:

pffttt....little bit of smoke dont hurt anything. I have 18-20% leak down in every cylinder and still put down 632whp with smoke guzzlin out the breathers :p


but anywho... i second the DSS shortblock. I dunno about their 4.6 stuff, but ive had a DSS 306 in my car for quite a few years now and it has taken a bunch of abuse and keeps on tickin ;)
