thanx extreme.. you gotta be the nicest guy on this thing so far. a few more

1. from reading in the past wasnt it either 6-bolt or 7-bolt mits. engines that had crank walk not "all" of them...? just curiousity..

7 bolts from 95 up turbo models (4g63) are the most likely to walk. 7 bolts from 92.5 are less likely to walk, but more likely than 6 bolts from 90-92.5. However, even 6 bolts have walked. On another note, I have NEVER heard of a 420a walking. Never. Now, spun bearings due to oil starvation or blown headgaskets (or cranked ringlands from overboosting). Well, that's another story.

2. i found the site for hahns but havent seen one for the star turbos.. anyone have a quick link

STAR doesn't have a site specific to their brand. However, a lot of people have been goign through importparts.com to buy them, as they seem to be both priced well and reliable.

http://www.importparts.com/shop/index.php?osCsid=698aab721893475804c0801c6898053d&manufacturers_id=46&osCsid=698aab721893475804c0801c6898053d

Don't just buy one from anyone as people have been scammed before on STAR kits.

3. are there any sites that are specifically for eclipse/this 2.0 liter engine that show different turbos likes the t3/t4 you mentioned. I honestly know a little about internals but very little about turbos (i took apart a 2nd gen ford escort engine) and superchargers... are there any superchargers for this engine as well? (yes i read the supercharger topic and there none at the time)

Nope, no superchargers for our car unless your're a fabricator and can modify a supercharger to work with our cars. It's possible, but due to the overwhelming popularity and inherent advantages to turbocharging over supercharging, people have decided not to travel the path of no fruit.

THIS SITE is specific as you will ever find for the 420a non turbo eclipse engine. Different turbos? Well, you can read about different turbos all over the web. Most people here use the Super 16g turbo that's described at hahnracecraft.com or the T03/04e turbos with STAR. The latter turbo's as popular as a turbo gets though and you can read about that one anywhere and everywhere that talks abotu boosting 4 cylinder engines.

4. im assuming the 2.0 is a 420A?

Yep, the 2.0 is the 420a (Chrysler made engine). That's the same lower block you'll find in any non-turbo neon. We have basically the same heads, but oriented in the opposite flow direction.

The engine and crankshaft can throw probably as much HP as you could ever throw at it. No one here has ever met that threshold. HRC has taken it past 500HP without failure. Just change out the rods and pistons, and you're golden.

You'll only find the entire 420a in the 95-99 eclipse/talons/avengers and sebrings. Neon guys sometimes don't liek their engines referred to as the 420a as they have different heads and OHC options.

5. sorry for all the questions, i spent over a year working on a 94 escort (port and polish everything, bored cylinders, reinforced rods, gude cam, etc)... so this engine is a little new to me

i know theres a million sites about turbos but is there one or in specific for beginners where i can just learn about all the different components, etc. Thanks jamez

To learn about turbos, you can read about them in a great book written by Corky Bell call "Maximum Boost", or something like that. Howstuffworks.com is also a fantastic beginner reader.
