94 Mustang 5.3 LS Swap

This project I started back in December of last year. Started with a 94 Mustang V6 roller that was in decent exterior shape.



01 V6 engine someone had transplated in.



Engine removed



Cleaned up



5.3L Silverado engine with about 80k miles



Original interior



Gutted



I found 90% complete interior from an 04 Mustang at the junkyard to put in the car. New dash in.

UPR adapter plate and 4.6 motor mount



Cleaned out the excess crap I didn't need and installed new front suspension.



Installed an MS3 cam and 918 valve springs before putting the engine in.



Dyna tech 1 7/8 headers with v band clamps welded on and installed on the engine, TH-350 with manual valve body.







Holley HP EFI to run everything.



Took the existing crossmember and cut out the center and had 2x3 box tubing welded in to make a new mount for the trans.

Relocated the fuse box to the fenderwell. This is 95% drag car and 5% street car so I'm not too worried about driving in the rain.



The brake lines were a mess so I took everything out of the engine bay, went to manual brakes and ran them into the fenderwell.



Holley mounted in the dash.



New interior coming together.



Using the factory gauge cluster I gutted it out and made my own mounting panel for Holley gauges.





Painted the engine bay (should have done it before I started but oh well)



Strange 35 spline axles and 9" housing ends, mounting brackets.



8.8 that came out of the car that I later found out was actually a rear from a 99.

LS6 intake and engine wiring harness installed.



Mocked up the rear wheels to get measurements for the rear end.



Rear housing narrowed 1" on each side (axles were made for a 94-98 housing plus I wanted to tuck the tires in a little extra if I could). 9" housing ends welded on, axle tubes welded by Tig Vision.



Fuel system installed, getting closer.



Starting it for the first time.

Kirkey seat installed and most of the interior together, B&M ratchet shifter, air bag deletes.



Custom 3" all aluminum exhaust.



Cervini's lift off cowl hood, Cobra front bumper.



UPR rear suspension, custom anti roll bar set up.

First time out to the track about 2 weeks ago. First pass off the trailer went 11.73 @ 116, this video is the second pass and last run I went an 11.63 @ 116.98 after adding some timing.

1994 Mustang 5.3L LS Swap 11.74 @ 116.71 - YouTube

A few days later I took it out and ran it on the transbrake and got that down to an 11.58 @ 117.39 with a 1.66 60 foot. The converter is an FTI set up for nitrous so it's pretty lazy down low. I'm still working on leaving at higher RPM to see if it helps but as you can hear the above video it flashes to 4400 and sits there for 60-70 feet before it starts moving. Should work really well on the spray.

15x10 with 6.5 bs, 275/60/15's but I have a slightly narrowed rear end. I purchased an axle kit for a 94-98 car and it turned out the 8.8 from a 99. So the housing was narrowed a little more than what a factory 94-98 housing would be.

As nasty as those seats where you wouldn't have wanted them. I know what you mean though, those but ones that don't stink.

They are the most comfortable seats. I had them in my old car. I had people with leather wanting to trade all the time.

I ran a new best last night with 150 shot. I'm going to pull the converter and get it tightened up but pretty happy with the combo overall.

I'm using F-Body water pump, crank pulley, the manual tensioner I got off ebay as well as the alternator bracket.

This is the alternator bracket.

Did you use the stock V6 radiator? And could you get away with running V6 springs in the front

I'm not sure if the V6 radiator would work or not. I used an LS1 radiator and fan assembly, mostly because it would work with all the radiator hoses/vent lines from the engine. The car I bought was a mess the lower radiator support was hit pretty hard and they rigged up some cheap electric fan and the original v6 radiator was trashed so I tossed them.

As for springs they would work but wouldn't be stiff for a great handling car but wouldn't be necessarily soft enough as a 4cyl drag spring. They would work as a temporary solution.

95 Mustang LS Swap

This is my first time posting on this site. I have a stock 95 3.8L mustang and I am looking at an engine swap and I would love to do an LS swap like you did.

I have never done an engine swap so I am in the progress of doing a lot of research. The most I have ever done so far is to change a cam in my audi a6. It was a bear but with the help of the awesome people on the audi forums it was easy, time consuming, but easy.

I have found LSx4U.COM and they sell used sl engine packages which include the wiring harness.

I want a project that is going to beef up my car and keep it on a budget. I don't intend to race or anything. I just want to drive it around town on the weekends and use it as a grocery getter.

I believe my current transmission is a T-5 but I am not sure. If you guys could shed some light on my project and point me in the right direction I would really appreciate it.

Any information is greatly appreciated.

Best thing to do would be read through my complete build thread at this link.

94 Mustang 5.3L TH350 Swap - LS1TECH

If you haven't done something this then take your time reading. In fact after you've gone through my thread maybe look up a couple of others. Mine is more specific for a track car not a street car.

Also update to this thread, new best with 200 shot.

Race weight is 3125lbs.

The car 60's really good considering the power. Last time out I had a 1.33 60' but ran out of bottle at the top end. Next pass I had a nasty backfire and did some damage so it's time to begin building my turbo set up.

Do you like the Holley Gauges? Do you have a wheel speed sensor? I'm just looking for a way to get a speedometer.

Yes the gauges are really nice. No I don't have a wheel speed sensor. I don't do much street driving with it so after a couple of times of looking at my phone GPS and 3rd gear RPM I figured what 45 and 55 MPH was and just used RPM.

I heard that some one figured out how to take the TSS sensor feed from a newer transmission to make their own speedometer but not sure with the TH350 or 400.

You can buy a speed sensor that will bolt into a 400 and you can select it to display.

I did this on my car it bounces a little due to it not being a digital signal but does get the job done.
