I have a complete A4 2001 Trans Am I just picked up. I'm thinking of the beauties of the LSX design now and all the advantages. For what I do with my car, there is not a single disadvantage to the LS1. I drive my car hard, and it'd be nice not to have to worry about it stalling under hard braking or off throttle cornering. Shaving a few hundred pounds off the car can only be a great thing performance wise, and the damn bottom ends are nearly bulletproof. It would be nice for it to warm up faster. The mileage is nice. I use the car as a D/D. Retrofit cost is high though. I'd like to change that.
Anyway, being I have the entire car, what would I need to save/reuse to get this thing installed and running in my '73 as cheaply as possible? I figure the entire car is in my garage runnign right now, everything I really need is there besides things needed to make the darn thing fit. Looking for functional right now, not pretty.
I'm also thinking about keeping my BTO 2004R instead of the 4L60, just because its already built to Stage 3 specs. Assuming I do keep the 4L60E, Besides VATS(they have that VATS thing on ebay), and the rear 02's(sim's?) what specifically will need to be changed regarding the harness and the PCM? What might it be looking for that I could swap over?
I'm also kind of tossing around the idea of using the 01's gauge cluster, being it will receive the correct signals as is, and it looks kind of cool.
Heres a question... since my '73 steering column is very basic, no tilt, no dummer on the stalk, no wiiper delay, no cruise, etc, and if I can find a '81 T/A with those options... could I take the steering column, and then use the new column to be able to use the cruise control switch? Thats a mod I'd LOVE to have on an older car. Has anyone else set up a cruise control using the LS1 stuff? If so, how?
And further more,whats involved with modifying the harness? I found all the pin-outs over on LS1Tech, do I simply remove whatever wires I don't need? Ideally I'd REALLY like to do this, to get it in and running, as quickly and as cheaply as possible. I can tidy it up later. If it simply means pulling the wires, or even just leaving them disconnected and bundled up, I'll do it. Theres not a lot emissions wise on the LS1, and most of it looks like it will swap to the '73 fairly easy, with the exception of the evap system and the rest of the gas tank. Still not sure how I'm going to do that, Any ideas? I looked closer at the two tanks last night and that LS1 tank is tall, I don't think the fuel pump/sending unit it even going to be possible to make it work in the '73, and the only way to get the LS1 fuel tank into the '73 would be to cut the trunk out. I don't really wnat to do that, even though I cant remember the last time I even opened the trunk.
The other option is to keep my existing tank and put on an external fuel pump (Walbro 255?)Now, how would I do the return? I notice theres a "T" fitting under the 01, is that how the 01 regulates it's fuel return? If possible I'd like to keep that. The idea is to buy as little new parts as possible.
Thanks guys.
