i dont know much about them but it might be possible that the bolt patterns for the exhaust manifold is the same as an eclipse, that would make things almost too easy. go to the auto parts store, get an exhaust manifold gasket for a 90-99 eclipse gst/gsx, get another for a 98 neon, compare the two of them.

will do. Should be able to find those at any autozone type store huh?

Well if the eclipse non turbo engine and yours is the same, then yo can check more info on guys that have turboed their eclipses and see how they did it, Just an Idea.

your engine is the same as the 2nd gen eclipse NT engine (420A) but i dont think they can handle much boost, there was a guy that worked at altered atmosphere over here in maryland and said they could only handle 7PSI, i used to have a 1st gen NT eclipse with a 4G63 and i think those can hold a fair amount.

ok i'm 90% done doing a hmt setup on my 96 sohc neon, and there are a lot of things that you need to know before starting this. i'd type out a lot but i'm at work right now, i'll try to put up a detailed post later- in the mean time try checking out neons.org and check out the forced induction board- a lot of good help to be found there.

Hey, I have a 99 r/t and i have been boosting for about a year now at 7psi on stock internals with no intercooler at 180whp. I could probably be at about 220whp with 7psi and an intercooler but i am lazy and i already have so much wheel hop and spin. It all depends on the turbo you have a less efficient turbo will produce more hot air at 5 psi than a better turbo will produce at 10psi. Proper tuning does wonders. I have run as high as 10psi at the track. I do run 94 octane gas all of the time and i don't have anything to pull out timing. I DON'T Recommend this to anyone! I have a warranty till 100,000 miles and i have all of my stock parts to put back on

Anyway that is my specialty - I make manifolds for the Neon, Eclipse Avenger and so on...

You will need a rising rate Fpr like a Cartech/BEGI or Vortech SFMU - regular vortech FMU will not work. you will need a higher volume fuel pump or in-line booster pump. The neon Fuel system is returnless, so you need to to disable the intank regulator and run a return line back to the tank fron the rising rate requlator. Oil lines are easy and pretty standard runs from a Tee off of the oil pressure sending unit and return it to the oil pan.

Nothing from a 4g63(stock turbo motor) Eclipse fits a neon!

and this "Neon engine is actually a Mitsubishi engine" is not right it is a dodge motor. The turbo eclipse guys call the 420a Eclipse a Neon with an Eclipse body kit

these are not stock internals but....
