Thank you for your input Civicspoon! Very much appreciated.
I've decided to go with the D16Z6 because the engine and parts are more readily available here in the US.
Im still not sure what route I should take for getting that engine.
Before I decide I need to figure out...
1. Is it really worth paying for and installing forged engine internals (pistons, rods, etc..)
Here are my options...
1. Most expensive route...Buy a remanufactured engine $2000 plus a core charge (which I dont have) $240. So that comes to around $2250. With this option I know that I am getting a good and reliable engine with a 3 year warranty. BUT, if I come to the conclusion that forged internals are worth the expense then it wont have them and I would have to tear it apart and install them. Which would be the most expensive route.
2. Mid range expense route...Buy a used engine for about $850 (asapmotors.com). After about 10 minutes of google searching this was the cheapest quote I found. And then install forged internals IF I find out that they are worth it or not. Used engines arent as great as a remanufactured engine but they still go through tests to see if they work or not. I would be taking a little risk with this option. BUT since I am planning to tear apart and rebuild the engine with either forged or regular internals then does it really matter?
3. Least expensive route...Buy an engine from craigslist and rebuild it.
So like I said, before I decide which route I wanna go I NEED to find out whether forged internals are worth it or not. Because they arent cheap! After this is all said and done and everything is put together I just plan on using the vehicle for daily commuting and the occasional "pedal to the metal" excitement. I do NOT plan on using this for any kind of racing applications. There will be occasions where I will rev the engine to high RPMs though. I just want to make sure i dont blow up my engine.
