I'm thinking about possibly boring and stroking my 2.0... I was wondering what provisions I'd have to make. I'd imagine that with a better set of injectors, an MSD ignition system and iridium plugs, it would be okay? Also do any vendors still make a stroker crank for 2.0's? possibly a Mitsubishi vendor?

Slightly bigger injectors are probably all you will really need. The factory ign. system will handle plenty more than a few cubes. You will spend way more than you want to even get to 2.4 liters, and those run just fine with the factory coil. There is a reason it cost twice as much as an MSD coil. It is more than twice as reliable.

At the most, you will probably be fine with '97 - '99 DOHC injectors. Those are 21lbs/hr @43 psi, 24 lbs/hr @58 psi. They work just fine in my 2.4 swap.

FWIW, SOHC 2.0's do well with the 19 lb/hr injectors for almost anything you can throw at them in N/A form. There is plenty of fuel there. So the DOHC's and maybe a Walbro/SRT pump should be fine.

Just buy my 2.6 Stroker motor and have Howell send you a flashed pcm. I will sell you more motor than you can handle for less than 2k.

Hey guys. Honestly I still love my neon. I could kick Darrell cox in the teeth for destroying the wiring like he did. Unfortunately owning a business and the time it consumes precludes me personally finishing the car. Everyone else that has touched the car has made it worse and cost me more money. I am either going to,part it out or store it for a day when I can rebuild it. Fwiw I have a 911 and a Mercedes Slk and still wish I had the neon. It was more fun than either of my Porsches.

High Praise indeed !! Shocked (For some people who still think the Neon doesn't deserve any credit whatsoever). Very Happy


Back on Topic:
There are different 'schools of thought' regarding boring out an engine, today.

In the 60's and 70's, this was an accepted, common practice.
Today, boring out a modern 4-cyl. engine -- In an attempt to increase displacement and power -- Is not recommended. The reason for this, is that today's modern, lighter, and thinner-walled blocks, will lose rigidity from the removal of too much material. (Less rigidity = more cyl. wall 'flex' = more blowby = less sealing = less power.)
Today's school of thought, is that properly round and straight bores, are the best for maximum power.

If boring out is to be performed, because of an out-of-spec condition, such as taper wear or out-of-round, then use of a Torque Plate bolted up to the block during the boring operation, is essential. (This was a technique endorsed by Smokey Yunick back in the day, when some considered it overkill.... back in the 70's.).

If you think about it, the 2.4 was really the factory version, of a 2.0 'stroker' engine, just as the MoPar 440-V8 was essentially the 'stroker' version of the 383.
Just like the 2.0 DOHC and 2.4 DOHC....The 440 and 383, shared the same cylinder heads.
