If you're going to swap to a DOHC, make sure you've got a manual transmission. DOHC + ATX = worst Neon setup EVER. SOCH + ATX is better.

 

You can keep the SOHC manual tranny. The DOHC sould have a closer gear ratio though, so it's worth looking into. You'll get better acceleration with the close ratio tranny (3.94 final drive), but tend to get worse gas mileage, particularly if it's the perf "A" tranny (shorter 5th gear).

You can keep the suspension, but check to see if the donor car has adjustable struts first. You can swap over sway bars/parts as well if they're better than what you currently have.

The 1995 SOHC is 132HP, the 1996-up SOHC are actually 128 HP. The DOHC's were rated at 150HP, but could easily range from 140ish to a little over 150 depending on how well the cams were set at the factory.

Best of luck!
