By the time you do engine harness, engine, crossmemeber, headers, downpipe, transmission, engine mounts, and all the TTA specific stuff like oil cooler for instance.. you can buy a 10K mile original TTA and still be ahead.
If you have the engine, and a wrecked TTA.. and been searching/picking up parts.. easy estimate.. 7-10K doing the work yourself..
The cross drilled TTA crank... hehehe
Good Luck finding one.
Anyone who has done the conversion.. will tell you the time/money involved.
And to put a manual tranny.. hehe..
Ohh I forgot you'll also need a rear end
Suggestion.. finance a 15,000 TTA thats low mile.. and instead of wrecking the pocket book creating ... enjoy driving.
Hard enough when you have everything in place. And when your done.. what will it be worth?.. That used TTA looks to be a lot less headache.
