I didn't realize you needed so much stuff. I can tell you that if I got a used engine I would have new rings, bearings, hone, and fresh valve job done while I had her out of the car. If you don't you will be pulling her out again in the near future to finish a job that should have been done before install. Who knows how long that engine has been sitting in a shed somewhere? Or how many miles are on it, or if the guy who had it before ever changed the oil like he should? Just my 2 cents.
If you go to Supraforums, you can find all those parts for less than $1K. I have watched daily for the deal I got on my HKS DLI, old Titan fuel rail, etc. Deals are out there if your not in a hurry.
You are should replace all the hoses/belts and most of the gaskets before install anyway. If you don't your asking for a lot of extra work. Don't cheap out on a non Toyota set of gaskets.
BTW, I just sold a set of 50K coils for $150, plus I have an ignitor for sale, $80. Cam gears are cheap because everyone has aftermarket gears. A map sensor, used less than 100 bucks, valve covers, all readily available.
Whats the known history on the engine you already have? I bet you can rebuild it, use new Toyota gaskets, valve job, and all the parts for not much more than the 5K your ready to spend, plus you will have a fresh engine. Your way, you will have $5K in an unknown engine with old gaskets, ? bad valves and ? compression. Been there before, good luck. And yes, the swap is worth it, but it will take longer and cost more than you think.
