Great Thread!!! I am actually doing the same exact thing this summer. Got a down payment on a 3rd gen 3S, getting it shipped when i get back from vacation. Also running the S54 tranny! Thank you for all the wonderful pictures and info! At first I was a bit worried the way the 3S would daily drive with the S54 but now I'm worry free.

I wouldn't say worry free... Manny's done a bit of work on his version of the S54.
You plan on upgrading the internals, yes?

...just an upgraded clutch, and lightweight flywheel.

Thats what I meant; a clutch kit that can handle the power a bit better than an OEM setup.

didnt really sound like it lol ..

thats not for brenttons dads car is it???? that would be dopeeee! lol

lol i wish this was going into my dads car haha but no realy i think im going to order one for his mr2 once i sell my civic, manny isnt that the one your doing for some kid in the city?????

You plan on upgrading the clutch at least, right?

yup, we went thru EVERYTHING before i checked the simplest thing. we even removed the fuel rail and swapped injectors..lol

a few more pics from yesterday.

tranny painted:



the comp clutch from dr tweak i got last year, looks pretty much like it did when i pulled it a few months after the install of the last revision of the 5sfte.



putting the motor in. normally we connect the tranny and install it together, but i didnt want to scratch the bay up after just painting it, so we installed them seperately.



the boot installed onto the firewall:



and now, the basics of the wiring that is required.

first is the interior plugs.

this black wire on the white plug:





is for the clutch start switch. we need to put it to pin 17 on this grey plug:



you can see the #'s for the pins on the back of the plug (sorry for the upsidedown pic, i forgot to edit it)



so i added a pin from one of the 5s harness plugs:



and soldered the connection:



and thats it on the interior.

next up is the EA1 plug in the engine bay.

this pic is the bodyharness side of the gt-4 EA1. the 3 wires on each end are extra wires that need to be used with the swap, along with a couple on the top.

with my 94, the connector for my EA1 bodyharness side was blocked off solid where those wires go, which was diffrent from jims swap. jims 95 had little rubber plugs in them that were able to easily be removed to add pins if needed.

so, we just removed the wires from the 5s bodyharness EA1, and transfered those over to the gt-4 one.
a pic pointing to the 3 wires from each side:





in this pic, the gt-4 plug is on top, the 5s one on the bottom.
basicly, it was as easy as removing the pins one at a time from the 5s one, and installing it into the 3s one.
easy peasy.


and a pic of the pin tool i used to remove the pins in action.



a medium saftey pin also works well.

once thats done, there are 3 wires left over, 2 need power sources, and a white with black stripe gets ground.
thats all there is to it!
lots more pics and vids later. unfortunately, its supossed to rain all day, so the vids will prolly be on the lame side for now..lol
