T5 conversion and various questions.

[At1Maverick69]

The RS is currently undergoing major surgery, to be more specific, it's getting a T5 and an 8.8 rearend. While still neck deep in this project, I have few thing I need help with:
*I have a double hump crossmember from my previous 90 GT, i was trying to put it on and it seems like its putting the tranny high enough to hit the floor board, is the problem the member, or the trans itself which is out of an 89 GT?

* The T5 seems to be a tad futher forward than the SROD judging from the floorboard hole, did any of you guys who converted had to make the hole larger?

* I also have the stock "headers" from the 90, would this work if I was to take off the flapper valve on the driver side manifold?

Any help would be very much appreciated. Thanks guys!

In 1983 they changed the "hump" on the tranny tunnel to accomidate the T5.
When I installed the T5 in my old 82 capri RS I did have to trim a bit of the tunnel to make the shifter fit.

you'll have to trim the hole a little. as for the "headers" they should fit fine. I used some off a buddy's 89 on my 84 with no problems. I assume you are putting on an h-pipe for a 86 to 93 then?

Is that something I'm gonna need to do? Wouldn't the stock y pipe work? I was thinking, for now while I attempt to put the correct converters on an O/R H-pipe, instead of the 3way cats that might get plugged up.

I have an '82 GT and had a '82 Capri too:

The T5 will fit, but you might need to trim the hole or just massage it enough to clear the top of the tranny. I made some relief cuts and opened the hole more by pulling up on the sheetmetal..

The crossmember will work, but I had to grind the welds on thebushing tubes so i could slide it back and forth (on the crossmember!). Once the tranny was in the car, I just had to adjust them to the correct place, then had them spot welded back up.

The headers will just fine if you use the corresponding '86-93 H-pipe. i had the full exhaust off an '86 and it went in with no drama.
