OK guys I've been doing lots of research and have found lots of info on most of what I'm doing here but I need to weigh my options and decide on a game plan before I start swapping parts out... I drive a 04 GT1 with 261,000 miles on it. 3rd owner, origional engine and transmission, purrs like a kitten and shifts great but the electronics are starting to give me fits and well who wouldnt want more options? I scored a killer deal on a 05 GTP with no title or key as a parts car. It appears to be fully loaded to my knowledge. Same color interior, heated leather, dual climate, hud, monsoon, 5 button, 10 spoke 17s (my favorite wheels)... you get the idea. The car was running and driving when towed and only has 138k on the odometer so it should have plenty of life left on engine and trans, although I have not got around to getting it started since I don't have a key... to sum it up the poor owner lost his only key, got the car towed from a public parking lot, then couldn't afford the get it out of the tow yard and have it hauled to a dealer to have a new key made. So it was seized for storage and sold to me for $400!
So here's my current situation. I see no need in swapping the engine or trans right now. I drive 100 miles a day so I want to squeeze all the life out of my engine/trans before I start running the clock up on the GTP engine/trans. And I want to take the time to save up for supporting mods to drop pulley size and do gaskets and general maintenence on everything. So for now I'm leaving that part alone.
I've already swapped the leather seats and I'll be swapping the 17s Monday after I pick up a used tire to replace one of the bad ones. Went ahead and swapped the GTP grills and I'm going to grab the exhaust tips too and get rid of those heanous black gt tips.
The HUD swap write up is simple enough as is the 5 button swap. The monsoon I could care less about. Already have a aftermarket head unit and system for the car that I need to install...
That's the easy stuff. Here's where it gets complicated... one of the biggest issues with my car is the hvac system. When I got the car it had the common water leak through the cowl. Owner had already replaced the blower motor but it still has issues I'm assuming all started because of the water leak. I'm not sure really. I fixed the leak and got a new cabin filter. I replaced the resistor but still no blower motor. Eventually I took a volt meter to the wiring and found out there's no 12v or speed signal coming from the control panel. (This is the 3 button panel with the turn dial blend doors and fan speed) So finally I got tired of not having air and heat and wired the blower motor to the battery with a toggle switch ground. Worked great for ac. I just turned the fan on any speed so the ac kicks on then flip my blower switch and I have ice cold air. Then winter came and when I switched the temp knob to hot it stopped blowing. I also realized on hot or cold nothing blew from the floor or defrost vent. Only face vents and only cold air blew. So I took a closer look at the heater box and realized it was broke in half where it's plastic welded from the factory. I've rigged it back up to where I will blow hot or cold now and vent selection works but it still isn't blowing hard. So I need a heater box and I need a hvac control panel. I was about to buy both of those until I got this parts car. I'd rather not deal with a dual climate hvac swap after reading several post saying "it's impossible" but I'd also rather not buy that stuff when I have good parts in this parts car. Not to mention I'd like to get these heated seats working. So I'll need the hvac control from the GTP for the buttons.
Basically I need some input from someone who knows what they are talking about or has experience with a swap like this. So since the heated seats and dual climate hvac rely on the bcm could I simply put the bcm out of the GTP into the gt? Will I also need to swap the whole harness in order to use the heated seats/hvac? And the most important thing to me is will swapping the bcm from a 05 into a 04 cause dtcs or security anti theft problems with my 04 ignition and 05 bcm? (Remember I have no key for the GTP so I can't swap the ignition.) My car has no check engine/abs/srs lights on currently and I want to keep it that way. And if I can swap the bcm is it possible to change the milage and vin stored inside it to match my car? I'm not against buying a tech2 if that's what it takes. Would it be simpler to reprogram my bcm to work with the heated seats and hvac?
Lots of questions guys I know but if you've read all of this and can help me out thanks. I'll post some pics of the cars once I find somewhere to upload them so you can see my swappage as I go along. This will be my official project thread.
