Yes, its possible, but it will be easier and look cleaner to pull the beam and heater core. Trust me.

the reason why i wanted to do the swap without pulling the dash because i want to keep the amount of labor time down so I can finish the swap on a weekend or something like that. Sorry i need to find wiring diaghrams for both cars so i know which wire to splice and which wire to replace. I was early morning when I posted that and my haven't really waken up yet. so it is possible without puling the dash. so what method should i use if i choose to go this route?

You will never get your first complete swap done in a weekend - it takes us 2-4 days at the shop, and this with 3 guys who have done it more than a few times.

actually pulling the dash and dash bar out isnt all that bad. you can do the whole thing with a phillips head screw driver and a 10mm socket and extension. and it makes things 10 times easier and it comes out alot cleaner. if you do pull the dash, just make sure you dont let your steering wheel and shaft assembly drop down to far. the rubber o-ring around the steering shaft in the firewall may pop out, its a project to get it back in. anymore questions feel free to ask me. kyle

to pull the heater core and the beam...is that just to help with the wires behind the dash or is that just to help out with the swap and its overall performance, or just to help and then be put back?

and also would it be a direct replacement if i where to buy a ver. 5 cluster, ecu, engine, and maybe the tranny (b/c i have a kaaz close ratio right now.)? BUT...would i need the "ver. 5" complete wiring harnese if i went this way?

You will end up with a sloppy harness if you don't pull the dash - you won't be able to chop you everything you'll need to.


Electrically, you can use a v5 tranny and cluster without performing any wiring work at all.

swapped RS :(

My RS-t That i purchased from a guy in NC was done without the dash being pulled. I must say that he did an awesome job! I disagree with the comments about it being messy. Mine is super clean.
