Toying with T5 swap behind 3.8 November 12, 2004, 06:31:17 PM ive been doing some slight looking around and whatnot for doing this swap, and had a nice discussion about it with Sancho last nightwe came to the conclusion that a 5.0 bellhousing will not work for the T5 swap due to the difference in the size of the flywheels, the 3.8L has a larger diameter flywheel that the 5.0 bellhousing will not clearanother issue that Sancho brought to my attention was that the 3.8L bellhousing is 3/4 inch longer than the 5.0's bellhousing, i dont know if this would effect shifter placement or not, or the driveshaftsomething else i need to look into is the shifter fork, does this interchange with the 5.0 or is it also a 3.8 only partjust some info for anyone interested Quote Selected

Re: Toying with T5 swap behind 3.8 Reply #2 – November 12, 2004, 06:49:57 PM this i know, but since im going to convert to a 5.0, i dont want to have to buy a complete 3.8L setup, just to pull it out and go with a 5.0 setup, id like to see what parts interchange Quote Selected
Re: Toying with T5 swap behind 3.8 Reply #3 – November 12, 2004, 07:44:04 PM Unless the 5.0 flywheel will not bolt to the 3.8 crank or the ballance is different, I see no reason a complete 5.0 setup won't work on a 3.8 fox body. Check to see if the 3.8 & 5.0 AOD flexplates are the same for say '87. If they are, then the 5.0 T5 setup will work no prob. Quote Selected

Re: Toying with T5 swap behind 3.8 Reply #5 – November 12, 2004, 11:08:39 PM alright, i looked up both flexplates in the allmighty advance auto website, the flexplates have the same diameter, same pitch, same teeth, but are still different, leaving only the balance to make up the difference Quote Selected

Maybe you could find a Advance or where ever with both in stock and compare. If the weight is of the approxmate same size and location you could still probably use the 5.0 flywheel(assuming it will bolt up). Caution its really tough to tell if bolt patterns are the same, usually there is just one or two bolts that are spaced differently than the others. Quote Selected

Re: Toying with T5 swap behind 3.8 Reply #8 – November 13, 2004, 09:07:16 AM the flexplates are the same diameter, the flywheels are notthe local advance is tough to get help like that from, they are the kind that if youre not buying something, they dont really want to help you, ill see if i can find any other source of information for the balance weights before i resort to pushing my nerves at advance Quote Selected

I'm sorta freinds with the Mgr at the local Advance(race with her husband). If she has a 3.8 plate in stock, maybe she will let me compare them. Quote Selected
Re: Toying with T5 swap behind 3.8 Reply #11 – November 18, 2004, 08:04:13 AM From the info in this thread, looks like the 5.0 flywheel will fit the 3.8 but the ballance is different(at least in the SC). Maybe the SC flywheel will work??? NAAWWW you just want to buy my TC, 5 speed already installed.http://forums.tccoa.com/showthread.php?s=&threadid=52654 Quote Selected
Re: Toying with T5 swap behind 3.8 Reply #12 – November 18, 2004, 04:35:59 PM its either the local guys or yours, both 5-speeds, so ill have a 5-speed either way!! i was going to put a 5-speed behind the 3.8L just to keep myself someone content with the cars performance, but i wont need to when i get a 5-speed TC Quote Selected
Re: Toying with T5 swap behind 3.8 Reply #13 – November 29, 2004, 11:30:36 PM I'm in the same boat as Tbird232ci. I'd like to swap a T5 in front of my V6, then upgrade to a V8 at a later date. I did some searching on the V6 Mustang boards but didn't find any concrete info that the V6/V8 flywheels have compatible bolt patterns. I've got a friend at Advance Auto who said he will compare the two on Wednesday. Does the SN95 V6 have the same bolt pattern as a Fox T-bird/Cougar V6? Quote Selected
