ok thanks.one more thing im having troble finding a head for a non turbo engine.when i call around they say that they need the old head to match up with the new one .well i dont have the old one.how is it posibble to match one up for my engine?

Find a 420a head on ebay, or look at dodge neons for them.  go to a junk yard, call around, go to the mall.

im talking 1g 89-96 years not 2 or 3 g
cars

They dont make a 1g eclipse with a 420a motor in it.  The 1g's all had 4g63, just some had a turbocharger and some didn't.  If it's a 1g, buy a manifold and a turbo and your good to go.
