Originally my plan was to jump up to the 2.4 turbo SRT-4. Throw some heavy horsepower into the 2GN and start winning rallies. Let’s break this down a little bit:
It’s all about the competition:
Open 2WD or Group 5 is an anything goes 2WD class where the motor can be as big as you want it, and as charged as you want it. This class only sports a handful of drivers in the country, and sometimes these guys still get beat by non-turbo Group 2 cars. In the Southwest, there are only 1 or 2 Group 5 (or CRS-5) classed cars.
Imagine you go for a podium or the 2WD win and you get beat by a hot-shoe in a tuned up VW GTI (this happens all the time). You finish the rally in 4th overall, you are 2nd in 2WD, and you get handed a 1st place trophy for CRS-5 because no one else is in the class. I’m sorry kids, but that participation trophy goes in the trash. 😐
Meanwhile, Group 2 (or CRS-2) has a ton of participants. 10-12 competitors at small rallies, 20-25 at big ones! I’d much rather race with 20 friends in class than compare times with a turbo. This decision was settled shortly after Prescott 2012: Eddie (tuned up VW GTI) beat us by 10 seconds to win 2WD, and we finished 5th and 6th overall. Because we were both in the same class, that 2nd place trophy will remind me of an epic Group 2 battle, and not a “you have a turbo, why did you lose?” Group 5 award.
Let’s build a hot motor:
For 18+ years now, the Dodge Neon has been spec raced, drag raced, street raced, autocrossed, and everything else in-between. If you can think of any combination of parts, there is probably someone who has run it and has a dyno chart for it. Thousands of threads in forums on every conceivable modification leads to a tried and tested set of things you should do to get your Neon 30-40 more horsepower.
We’re going for a build that will keep the mid-range torque and won’t require a ton of RPM’s to make power. That means no long tube header or individual throttle bodies. 🙁 The goal is strong reliable power. Rally is not a 14 second drag race, we’ll be expecting good performance on pump gas over a 100+ mile event. 🙂
The Dodge Neon All Motor SOHC Formula:
- Ported and polished head (professional job)
- Upgraded valves and valve springs
- Crane Cam #12 (158-0012)
- JE 10.5:1 compression pistons + Eagle rods
- Adjustable cam gear and mechanical belt tensioner
- High flow oil pump
- 2GN Intake manifold + throttle body
- Exhaust manifold
- Under drive pulley
- Megasquirt 🙂
(Rinse and repeat. Use only as directed. Your mileage may vary.)
This formula is setup to make good reliable horsepower across the entire rev range. With the Megasquirt there will be zero ‘goofing around’ with fuel pressure risers and pumps, crazy over-sized injectors, Air-Fuel piggy-backs, or DOHC computer swaps. Plus I have no restrictions on combinations like a 2nd gen crank with a 1st gen head and cam sensor. It’s all basically a dropdown menu and some settings.
The crank and block are cleaned up with new bearings and ready to go. I’m sorting through the head and collecting all the parts and pieces to begin engine assembly. A serious junkyard run has been planned – watch the Tumblelog for progress!
