I wasn't really shopping for an engine. I had my old supercharger listed on craigslist and this got offered up as a trade. It's complete ready to run 94 Cobra engine with 89k on it. The guy had pulled it 3 years ago in favor of a built 347 for his drag car. It had been sitting unused in his garage. Of coarse I jumped on it.
Engine swapping will begin immediately:D Anyone have experience with this swap?

Let the fun begin. Gonna be redoing my intercooler piping in stainless also. I want to weld it in a few places so I have less couplings to worry about. Also planning to upgrade the clutch while the engine is out. Tom was right about Spec clutches. This Spec is not holding the power it claimed it could.
So plans are:
-New FMIC piping
-mass air conversion
-Cobra engine
-Upgrade clutch (maybe ACT)
-Paint and install TC header panel

Lucky lucky!!!
The TC header panel will be a great addition!
I want a boosted v8 some kinda bad! Lol
You've already got the 5.0....you'll need to change your EEC though. I'd imagine an A9L will work great.
If you've got a set ready to go, I'd suggest some GT40's and changing the upper to a '93 Cobra style (to eliminate the freaky "elbow")
Use your car's existing engine harness, and call it done. :)
No experience with the exact swap your doing, since I used the stock panther SEFI harness which is a bit different, and the intake to has to be flipped, but I do have the 93 Cobra cam in mine. Great piece, finally made the sluggish E7 headed H.O. wake up below 2500rpm. I couldn't ever see going back to the stock HO cam now.
Generally you need quite a bit more rating hp rating out of a clutch than what you need I learned this from doing clutches twice on many cars... I got a really nice custom turbo grind from Ray Gab at comp cams if you are wanting a turbo cam. It is a hydraulic roller with 565 lift so you still use the stock spyder tray.
I have this cam for sale if your interested.
Cam: $150 OBO
CompCam HR#35-000-8
Intake 236 / .362 / 1.6 / 579 / 112+4 adv
Exhaust 242 / .360 / 576 /
since that is a cobra engine, wouldnt it already have the GT40 heads?
Yes, it already has GT-40's and 1.7 roller rockers if it's as Ford made it.
Yes, GT40 heads and I believe crane roller rockers. 24lb injectors. Under rated from what I hear at 240hp.
Personally, I would go ahead and upgrade to some real performance heads, before dropping that in, since this will be the easiest time possible to do so.
I think I will run the motor as is for now. I need to invest my money in a stronger clutch and transmission first. Anyway, I have a on my boost controller that I can turn up or down that allows me to run as much horse power as the rest of the car can handle.
I've been pretty slammed for time to work on the car lately, but I managed to remove my hood, pull my turbo stuff out, the radiator, and a few other things. Also picked up a new engine stand.

Here's a good shot of the hot piping for the turbo before pulling it.

Just a FYI you'll need to drill and tap a hole in the #5 intake runner for the ACT sensor so the lower will have to come off. I'd sell the upper to a 94-95 Mustang guy and use the funds to buy a Fox Cobra upper/tubular GT40 upper/Explorer upper as they all flow the same.
You're going to need to swap to MAF to run those 24lb injectors. You'll need an A9L or A9P and a calibrated MAF. Don't use a 94-95 GT/Cobra computer as they won't work with your stock wiring. The MAF swap is easy. If you have any questions about it just ask here or drop me a line. It took me three hours (maybe) to swap the computer, move two pins in the harness, and run the wires for the MAF meter. It is really stupid easy :D.
Yeah, I was going to get a calibrated maf with some 42lb injectors injectors and a A9L. I could definitely use your info on the harness mod. I'm at the shop right now getting the engine ready to come out. I'm exhausted from work, but super excited to get this done.
Anything past a 24# injector and you will need a custom chip burned especially with boost
I like your current set up from the pics
Really? What's the point of recalibrating the maf if the ecu would need to be tuned anyway? I thought these things were plug and play.
On a Cobra engine, the ACT sensor hole should already be in the lower intake on the #5 runner.
The computer still dose not recognize the larger injectors even know you have the right maf
I had to get a tune with a chip on my mustang running 30# n/a at full throttle it would lean out even with 55 psi of fuel pressure
I tune is worth it any way
A tune is definitely called for, because stock air fuel ratios and timing ate not ideal for forced induction, but I thought it would at least hold the AFR's within stock parameters. Did you have an adequate fuel pump?
255
That's what I have too. I think I'm going to order a Megasquirt ECM. They have a direct replacement that can easily DIY tuned.
I would go with a costom chip ..... That way you also get a dyno sheet lol
What version of MegaSquirt???
Travis
I have a MAF off a 2001 Mustang GT and 42 lb/hr injectors on my 331 but they were also on my 306. The guy that tunes my car prefers the OEM MAF's over the aftermarket units as the transfer functions on the OEM units are more accurate. I cannot argue with the guy as the car runs like a champ.
The 2001 MAF is an 80mm and the one off the 99-04 Lightnings are 90mm if you need a larger one. You can find the Lightning units for sale on EBay all the time and http://www.car-part.com has the Mustang MAF's for dirt cheap but you can find them on EBay as well. Both of these MAF's use a six pin connector but the outer two pins are not used on a Fox car. I just looked up the wiring diagrams on both cars and figured out how to wire it up. This site has the pig tails and a four to six adapter as well as the wiring harness to convert to mass air:
http://www.promracing.com/parts-accessories/wiring-adapters.html
Just thought I would through this out there for thought.
Darren
Is the 01 mustang MAF the same as using a 24lb. MAF as far as output voltages?
Had a little time to work on the car:D Got the engine and transmission pulled. Now time to clean the engine bay. Here's a few shots of the progress.
My home made turbo header being pulled

(http://i663.photobucket.com/albums/uu352/bryan163photobucket/IMAG0039_zpsf6e22ad3.jpg)
I have to get the fuel line tool today so I can disconnect the fuel rails and then some cleaning of the bay.
(http://i663.photobucket.com/albums/uu352/bryan163photobucket/IMAG0047_zps2cf4f502.jpg)
The 2001 GT MAF is not calibrated for any size injector (the 2001 GT has 20 lb/hr injectors as an FYI) and to my knowledge Ford does not calibrate MAF's to an injector size as this is in the EEC logic. A tuner will drop in the transfer function for the MAF (basically tells the EEC how much air is coming into the motor at a given rate by the resistance of the MAF sensor wires) and then the tuner will modify the injector tables to account for the larger injectors. That is a very rudimentary explanation but it gets the idea across.
Now I had a Bullet MAF calibrated for 24 lb/hr injectors. When a MAF is calibrated for a certain size injector it is just a poor way to trick the EEC into adjusting for the larger injectors. I had run out of room hp wise for the 24 lb/hr injectors and after some talks with my tuner I got the 2001 GT MAF due to it being 80mm (I was planning on a stroker in the future) and he had the transfer function for it so it was easy to make it work with the 42 lb/hr injectors. Now don't get me wrong, a calibrated MAF works for the majority of people but when it gets down to it and if you are going to tune the car they are junk compared to an OEM MAF and someone who actually knows how to tune a car.
Darren
Ok, thanks for the info. I'm probably gonna start with one calibrated for my injectors.
Darren, I totally get what you're saying. I know I will have the ability to calibrate for the injectors via the EEC. I just thought it might be nice for the start-up if I could fire it up and have it run decent on the base tune. This will be my first time doing my own tuning, so I was trying to keep things as simple as possible. I do already have a wide-band in the car that I used to dial in my AFRs on my old setup with my adjustable FMU. What kind of power were you making when you maxed out the 24lb injectors?
289 rwhp on a Mustang Dyno. The injectors were at 100% duty and idle characteristics were . The only thing we did was swap in the 42 lb/hr injectors and correct the tables for them and the car went 318 rwhp and it idled like a champ.
Darren
Got some things done yesterday. I sold the cobra intake manifold and 24lb injectors for $300. Gonna put that money toward some 42lb injectors and a MAF.

I was pretty happy to see these beauties when I pulled the valve covers.
(http://i663.photobucket.com/albums/uu352/bryan163photobucket/IMAG0080_zps8fd0d303.jpg)
Double valve springs with Crane rockers. The motor is super clean inside:)
(http://i663.photobucket.com/albums/uu352/bryan163photobucket/IMAG0088_zps10a40b5f.jpg)
I stripped the flaking paint off the valve covers and painted them.

I stripped the cobra motor and SO motor down to the long blocks to swap the intake, 70mm TB, timing cover, water pump, distributor, and accessories.

Gonna be working on painting the block, obtaining new, gaskets and dressing the motor today.
Sweet score man
I would get a different intake if you could. The stock lower is holding you back unless it's been ported. Those valve springs are actually stock but they look to be in good shape.
You should paint the block/heads while the engine is out. I like the color on the valve covers. I think it would look good on the whole engine.
^ I have to agree with all the above. ;)
Found this on one of the Mustang/Cobra sites so I am not 100% sure if it is all legit but it has been posted several times on the Cobra sites and no one seems do doubt it:
Cobra Engine/Trans Specs:
The Cobra engine was under rated at 240bhp from the factory campared to the GT's 225bhp and was only available with a 5 speed and 3.08 rear end gears.
Cast iron GT40 heads
Cast aluminum Cobra intake manifold
Crane 1.7 rocker arms
24lb fuel injectors
Cobra specific ECU (computer)
"Cobra" stamped valve covers
Engine oil cooler
Front mounted power steering fluid cooler
Lightened flywheel
Phosphate coated transmission gears
Under drive water pump and crank pulleys
Cobra specific camshaft
Cam specs: Duration: 227°/Intake & 270°/Exhaust
Lift: .485/.485 Intake/Exhaust
Lobe separation: 118.5°
Alot of the other sites stated that the valve springs are actually a spring with an inner damper as the cast iron GT40 heads have to be machined to accept true dual springs. For the most part the springs of choice for these heads are here:
http://www.summitracing.com/parts/TFS-2500100/
My advice would be to get the TFS spring kit and install it now because having to do it later will cost a lot more $$$. I've never been able to assess springs by appearance, they need to be checked by a machinist to see what the seat and open pressures are and from there you can say whether or not the springs are good for the application or not. They do make spring testers that the average Joe can buy but most of us are not checking spring pressures enough to warrant such a tool especially if the heads are already off the car.
Darren
I did end up painting the block and heads last night. Also swapped over my fox timing cover and water pump and a new front main seal. As for upgrading the springs and intake, It's not in the budget for now. I still need to buy a clutch, injectors, MAF, and megasquirt. I need to get this car back on the road ASAP. I drive 2-3 hours a day and my truck is killing me on gas.
Note the cobra's timing chain. It's a single wide chain as opposed to the double chain on the SO motor. Also the oil cooler ahead of the filter that ties into the cooling system.
(http://i663.photobucket.com/albums/uu352/bryan163photobucket/IMAG0117_zps7c6b8658.jpg)
Looks good painted up
Could you swap on a new chain while it's apart? It's easy to do right now.
Its no longer apart. Lol
(http://i663.photobucket.com/albums/uu352/bryan163photobucket/IMAG0184_zps2ca5d689.jpg)
Progress for sure....
Travis
Dude, as Emrile would say, "BAM!". That bitch is done...this man does not know the words screwing around. It will be good to hear how it runs with some boost???
Darren
I just ordered the clutch. Once that comes in I can drop the motor in. In the mean time I will probably make some solid engine mounts out of the old ones. I'm out of money this week, so injectors and megasquirt will have to wait till next week.
This is how I plan to run my belt. just running an alternator and a water pump.
(http://i663.photobucket.com/albums/uu352/bryan163photobucket/Fox_50_Smog_AC_PS_Delete_zpsc65004d4.jpg)

I think I'm going to ditch my home made turbo header on the passenger side and make a new one out of this stock header. It will be a lot easier to get the bolts in and out. I'm also changing my standard V-band s to the kind that have an interlocking male and female so they wont leak under high pressure.
(http://i663.photobucket.com/albums/uu352/bryan163photobucket/IMAG0234_zps78edc999.jpg)
Neat project...so how is it proceeding?
Travis
Everything is going really well. The car should be done in time for my next drift event on June 22nd. The motor is dressed and ready to go in, but I'm going to wait until I get my new clutch and V-bands before I put it in. It will be a lot easier to do with the engine out.
(http://i663.photobucket.com/albums/uu352/bryan163photobucket/IMAG0254_zps3e21f623.jpg)
More progress. My new V-band s came in and I made the needed alterations to the turbo manifolds.
welding a onto an extension to compensate for the new passenger side header:

This is where the extension was needed:

Also got a new clutch. SPEC stage 3
(http://i663.photobucket.com/albums/uu352/bryan163photobucket/IMG_20130424_015253_zps2b7b721c.jpg)
I should be getting my 42lb injectors tomorrow night.
looks good
i like my spec 3 but heavy very grabby and will kill a stock t5
I have a SPEC stage 5 in my Maxima. It's pretty harsh. Hoping I won't have to go that crazy with the tbird. We'll see how she holds.
Nice! Getting closer! :burnout:
I just noticed that I got the wrong clutch. The ebay auction title said "SPEC Clutch Kit Stage 3 Ford Mustang 86-95 5.0L", but I just noticed that the clutch they sent is a 26 spline, and I need a 10 spline for my T5. Did I screw up, or is this the sellers fault? I thought 86-95 mustangs were all 10 spline.
This is the eBay auction:
http://www.ebay.com/itm/310321876854?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 (http://"http://www.ebay.com/itm/310321876854?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649")
86-95 Mustangs were all 10 spline. The seller provided the incorrect part.
10 spline are standard on T-5s & T-45s. My T-45 from a 98 Cobra is a 10 spline as is the 11" clutch setup from 2000+ 4.6 GT. There are up-graded 26 spline input shafts though. But yes, the seller sent you the wrong disc.
that sucks
Thanks for confirming. That's what I thought. I sent them a message last night informing them of the problem. So far, no word back from them. Sucks because I'm about ready to drop the motor in, but it would be nice to have the clutch bolted to the flywheel. One less thing I have to do under the car.
Well, I finally got the right clutch. I had to return the disc to SPEC and wait for them to send the right one. They admitted that they had sent me one for a t56 by accident. My injectors also arrived. I got 42lb. (440cc) flow matched.

looking good man
Just finished my ms3 with ms3x card install. Was very easy to install the tuning is a lil difficult for me. Ill get it tho. Got it fired up yest. If you have any questions with install i can help
This is the kit I ordered:
http://www.diyautotune.com/catalog/megasquirtii-v357-plug-and-play-for-19861993-50-mustang-p-418.html (http://"http://www.diyautotune.com/catalog/megasquirtii-v357-plug-and-play-for-19861993-50-mustang-p-418.html")
Finally got her running!
[video=youtube;TgyQsfJWNmI]http://www.youtube.com/watch?feature=player_detailpage&v=TgyQsfJWNmI[/video]
says the video is private buddy
what a tease !!!!! lol
, I don't know why its doing that. It works for me obviously, but my privacy settings must have changed somehow. I'll see if I can upload it to photobucket.
Ok, got my privacy settings fixed on youtube. I dont know how it got set to private. Anyway, I took the car out last night for a test drive. Ended up coming right back to adjust the clutch cable. Gonna play with the tune a little today because I was getting a little hesitation when I stab the throttle. Probably needs a little timing adjustment. Over all everything looks great though. I'm very happy. I was literally jumping for joy at 4am the night I stayed up and got it running. Gotta add cobra swap to my sig now:)

nice man
Thanks guys. Here's another engine bay shot.
(http://i663.photobucket.com/albums/uu352/bryan163photobucket/IMAG0616_zps07e26c0b.jpg)
Did a little tuning and took the car to a local cruise spot tonight. Had a blast driving it after having it laid up for so long. Trying to take it easy while I break in this new clutch has been hard.
Not sure how I missed this thread before. I am fairly new here and have not read everything on this forum. Very nice build and like what you have shown. Did not see or might have missed your Garret turbo specs. I guess you are running lots of gear for what you are doing with the car though. I knows its old now but in case anybody else can use the info, The Mustang Cobra 5.0 cam is the same camshaft that is used in the 1991/93 5.0 MN-12 Birds and Cougars, except those cars have only the E7 heads and stock 5.0 HO 1.6 rockers. I like how you have the turbo on the left side compared to most on the passenger side. Looks really good, sorry for chiming in so late.
Thanks. I don't know all the specs on the turbo, but the turbine housing is a t3 with a 1.12 A/R housing and a 3" 4 bolt outlet. The compressor is not stamped with any info. I got it cheap from someone who didn't have any specs for it. My gearing is not really ideal for what I do. It will be changed at some point. Good info on the cam. That's a great low budget cam upgrade.
I've been driving the car a lot this week. Managed to put 1,000 miles on the trip counter since the engine went in. Everything is good with the swap. I'm gonna go ahead and register for a drift event for Aug. 10th at lime rock. Can't wait.
Sweet man get some vids
I definitely will. My girlfriends 12 year old brother will be my co-pilot. Gotta start'em off young.
