Help Me Figure Out How To Build My Engine

Post by Mopar65 » Tue Feb 10, 2009 11:12 am

Hey guys Im looking for opinions, ideas, etc. on how to build up my engine. I have a 2003 SXT with the 2.0L SOHC engine. My performance mods are an AEM CAI and the R/T Dual exhaust rear section. I think Im putting out a hopeful 140 horses, but I want to kick that up anywhere from 50+ and beyond. Im not looking to turbo the car currently, but plan on it eventually so I need to build up my engine in pieces and correctly in order to handle the big turbo that I plan to set it up with in the future. My main question is then what the hell should I do to it so I can add 50+ horses now and build it so it can later handle a big turbo? I need a setup that is good for Daily driving, but can still raise some hell. I need opinions on what head to put on (SRT vs. R/T), Cams, Intake manifolds, Exhaust manifolds, internals, etc. Thanks for all the help and ideas. :thumbup:

1. Your probably putting down 125 to 130HP with those mods

2. If you are going to do a head swap you can only swap to an R/T Head as the SRT Head is DOHC and your Neon is SOHC. Physically the DOHC head will bolt up but the computer in your car won't really know what to do.

3. If you are inisting on using a DOHC Head then you will need MegaSquirt.

4. People on this forum have spent many 10s of thousands of dollars trying to reach the mythical 200WHP from the 2.0L Naturally Aspirated. If you want 180HP do a shot of NOS or build a turbo setup.

5. If you want to go turbo, do an SRT Swap its cheaper (search for threads on this. Yes. Its Cheaper).

Best of Luck to your endevours

You want speed? Go for a different platform, or turbo/srt swap. In which case, they're a ton of different threads in every section of this forum.

Generally, adding things to the neon motor just lightens your wallet and makes it sound a little cooler.

Poor Andrew put *does rough estimate* $600-$1,000 in his motor, got a few horises.

I put $500 and get 60 horsies. :D I tried the whole, bolt ons + neon thing. It was the biggest waste of money...ever.
