Hey guys its the bench racer here lol,i just came into i think is a once in a lifetime deal.my Nepfew has a 00 stang with many mods to the motor and trans cams, dual stage clutch,headers,hes getting tired of it i think and he talking about selling it, we was bsing the other day and there a possiblity he is going to let me swap motor and trans into my car which is a 96 non pi motor.my questions are how bad of a swap is this? i know ill have to get a wiring harness for the COP igintion and a diffrent sped sensor since his is a 3650 trans,but other than that its a pretty much straight forward switch isnt it? would i have to get a newer ecm and the harness for the engine bay or can i use one of those wiring kits ive seen for switching from coil pack setups?little lost as to what ill need and he does have a programmer for it so im assuming ill have to switch ecm, any help would be great

[chris91]

Thats a simple swap. You dont HAVE to run COP. You can get away with running your ignition. Of course if its cammed and such youll need a tune. Is the 3650 built? If not Id just run your trans so you dont have to mess with the speed sensor. The T45 is stronger than the 3650 anyway.

[highmileage4.6]

Hey has the accel cop on it, so would love to just carry stuff over, i talked to him about it more talked about letting me swap ecm and wiring also

[highmileage4.6]

Another thing i was worried about is his car is the returnless fuel system wondering if i could get away with useing my injector setup up

[highmileage4.6]

Also thought the 3650 was the stronger of the two trans

[draggin50]

Yeah I thought the 3650 was stronger too. I got a T45 and its junk!

[chris91]

I always thought they were. I could be wrong.

[Blackout]

I have done the swaps around 50+ times. Its not a big deal. You will want to use your stock ignition and fuel system. You will basically be swapping bare longblocks. Your biggest challenge will be the coil pack brackets. Other than that, its simple.

About the Accel COPS..... if your not running crazy high HP then I wouldn't worry about it. You stock coil packs will work fine and be sufficient. There is no need to change it all over.

[cstreu1026]

Like it was said above...swap the long block and reusue your accessories, front cover, trans, etc.

Problem I was loooking at was the use of the timing cover. Its a Windsor motor. 96 has the Romeo.

[cstreu1026]

Yeah theWindsor/Romeo thing makes it a little more difficult but but isn't it just 1 hole in the cover and the size of the bolts that differ?

[Blackout]

If I remember right, its the valve cover bolt holes. I think they are a touch different. Now as far as the timing cover bolts, yeah there are like 3 bolts that are different. Really nothing major just will take a little looking at it and seeing what will bolt up. One of the pluses though is the tensioner are the same.

[chris91]

I threw a Romeo engine in my Windsor car and all my accessories bolted right up no problems.

You are correct the 3650 was rated higher on torque spec handling stock @ 360 ft/lb. THe T45 was rated @ 325 ft/lb stock. The T-45 likely has more aftermarket parts available being it was used in the mustang from Fox body through to 2001 before the Tremec 3650 replaced it. I've read articles and if my mind serves correctly the T45 was even weaker pre 1992 before it received some workup tthat got it to the 325 number by the manufacturer.

The tremec in my 05 fed 507/473 to the rear wheels and had no issues doing it. Only drivertrain mods on that car were clutch/fhlywheel/ss feed line to the slave cylinder.

In the end both are great little trannys IMO in the end.

[chris91]

T45 was used 96- early 01. Foxes had the T5.

oops...my bad. I forgot about the T5. So was the T5 in the 94-early 96 models or was that as well the T45?

[chris91]

Easy way to remember. T5=5.0 T45=4.6

[cstreu1026]

T45 vs 3650 is really splitting hairs when it comes what they will hold up to.

Coooooollll! I like things like that. Like ROY G BIV which gives you the colors of the rainbow in their proper order.

valid point. guess I was thinking T5 V 3650 before I learned what was just expressed having never owned a foxbody. Good learning data. THanks

[chris91]

Always nice to learn new things. :D

[blown96cobra]

I've always had better luck with the t45s. As long as the 3rd gear fork is welded it should b pretty hard to break.

[dr59l]

I know my old t45 in a 00 gt w 4v swap didn't last long before had Troy putn a gearset in it
