302 into 84 turbo

hello, new here.

I just got my hands on a fairly clean 84 turbo T-bird. it has everything except the motor.

Now, since I don't have an engine and turbo-4s go for about 800+ around here, IOW 600 more than 302s, I am most likely going to go with a 302, since I already have a T-5. I might turbo it later (I like the Turbo badges).

Do I need to change the k-member or just the motor mounts? I imagine the wiring harness will need to be changed as well. Are people on here opposed to using MegaSquirt DIY systems? If I can use this, I would fabricate an intake and use ITBs. A later TC hood would be cool to feed it. 

I plan on doing a SN95 4wdb 5Lug conversion in addition to some lowering springs, is there a photo gallery where I can see different members cars with different wheels on them? I want to see some 18 inch bullets on a lowered 83-86 bird, not very specific huh?

You can use stock mustang motor mounts. The 83-85.5 cougars and birds use the same k-memeber as the mustangs.wiring you can use any 86-88 cougar/tbird with a 5.0 or if you want wire in conectors, you can use a 86-93 mustang 5.0 harness.

If you want to go carbed, it would be alot easier with very little work to change things around. Which ever you decide to do would work fine. You also have basically a mustang length axle and suspension. The control arms and struts are different on these cars. As far as springs go, there are some threads around here you can search to get you exactally the look you want. Mark7 stuff will not clear all rims, so you would want to go sn-95 on your suspensions parts.

The sn95 suspesnion swap is fairly straight forward. You will find all you need and them some from searches here. Alot of people have done this swap, and someone will chime in that knows alot more about it then I do.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

You got that partly right...

On the 83-86 cars the FRONT control arms are the same as the Fox Mustang.  The rear control arms are different (longer) than all Fox and SN-95 Mustang.  The SN-95 brake parts (which are the better choice IMO) will drop in with minimal work.

You will use the Mustang motor mounts.  Go MegaSquirt if you think you can do it.  It's a good system.

Also, I think your engine pricing is a bit skewed ;)  but whatever floats your boat.

That's one way folks try and justify the 302 swap ;)

not really, those are prices found on Craigslist. However, If you add things up, going past the stock hp on a turbo 4 is more expensive than adding hp to a 302.  Plus to tell you the truth, I like the sound of a cammed V8 a lot more than a turbo-4.

so will stang lowering springs work? I am going to have to do a lot of searching, I want to lower it about 2 inches and put some 18s on it.

Thanks for the warm welcome.

around here the cheapest 2.3 turbo motor I have ever seen was $600 locally. The regular 2.3 you can find at the junkyard, but only out of 2.3 mustangs. overall it is alot easier in alot of ways for me to do a 5.0. I would stick it out with the 2.3 personally though. I have had a woody about them for a while.

And chuck, sorry, I was pretty tired when I typed that up.

There are quite a few turboford and Merkur guys in the Chicagoland area, but again, it's your car to do with as you please.

oh, I know, but they apparently think TC parts are gold. I can buy a complete car for a little more than they want for the turbo-4, but I don't have the room for a parts car.

BTW, my wife has the computer that can get the pics outta the camera and she's laid up (wisdom teeth pulled the other day).
