Recommended Vendor Performance parts:

The key part from Beyond Redline Performance that I recommend for DSM, GVR4, and Evo 1-3 owners is their Custom Hardened Chromoly Cross-Shaft to use in the 4-spider center differential upgrade.  It is by far the strongest cross-shaft on the market for these vehicle applications and provides owners with complete streetability on high-horsepower AWD applications.  Instead of machining down the stock cross-shaft to accept 4 spider gears, this part started from scratch with better material, a beefier structure, surface hardening, and oil passage grooves on its posts to provide proper oiling to the spider gears to prevent surface galling.  The Beyond Redline Performance cross-shaft has been proven to hold over 1000HP and 950TQ at the crank on my race car for the last 6 years without signs of galling or damage.  It has been proven on the race track, the street, and the dyno to survive the harshest conditions without failure.

The key parts from Frontline Fabrication that I recommend for modified 1990-1999 Mitsubishi Eclipse/Eagle Talon/Plymouth Laser (DSM 1G/2G AWD) and the Evo 1-3 and Evo 4-9 platforms is the custom Billet Aluminum Custom Rear Differential Cover with Load Caps. It is easily the strongest rear diff cover on the market today and is what holds together the backends of some of the fastest DSM's running preventing rear differential housing failure.  This is what I run on my race car in place of the "like glass" OEM cast aluminum part that is fail prone when you start making real power and want to go fast.  Frontline Fabrication also makes Billet Aluminum Custom Transfer Case Braces for the 5-speed and automatic DSM transfer cases.  The brace fits on all 1991-1999 transfer cases and there are two different designs (one for manual; one for automatic).

The key parts from Performance Autowerks (PWerks) that I recommend for stock to heavily modified Dodge Neon SRT's start with their Carbon Fiber Lined Synchros, their Billet Steel Shift Selector (a recommended upgrade for all power levels), their Billet Steel 3rd/4th Shift Fork for heavy shifters (a great upgrade for modified SRT's that are getting a performance rebuild).

About The Owner:
I have been an active wrencher and tuner for over the last decade on a range of vehicle platforms including Mazda, Toyota, and Diamond Star Motors vehicles.  As well, I have owned Mazda RX-7's, and several DSM's (Mitsubishi Eclipse, Eagle Talon, Galant VR-4) over the years.

I am an active member and technical contributor on numerous forums including:
*DSMLink Forums
* Forums - Australia
* Forum - New Zealand

My USER ID on all of these forums is:  "twicks69"

I currently own one DSM -- I have sold off all the others along the way.

The "race" car is a 1999 Minden Pearl Silver Mitsubishi Exlipse GSX that is very heavily modified, and is one of the quickest/fastest 2nd Gen (1995-1999) STREET DSM's in the country. It is also one of the highest-horsepower and highest-torque 7-bolt 4G63's in the country with currently 1004 AWHP/720TQ (power at all 4 wheels) on a DynoJet AWD dyno at 48psi with the current engine/turbo setup. The pump gas tune made 714 AWHP/530TQ at 29psi.  Dyno numbers are from August 2013.  The car was also dynoed in FWD mode later in October 2013 and made 805WHP/506TQ at 29psi, and 944WHP/579TQ at 40psi, effectively resulting in a 29% drivetrain loss in AWD mode and a 15% drivetrain loss in FWD mode.  This produces a number around 925HP at the crank at 29psi (wastegate spring pressure).

2014 Season had no major changes to the car, just some aero modification.  It was at the 22nd annual DSM Shootout in August, and was kept at a conservative tune since there was no free time this year to do any testing prior to the event.  At only at 30psi with an extremely soft 1.68 second 60-foot, it ran 9.5 at 154mph 1st pass off the trailer.  There is a huge amount left in the car. 

As of 2012 Season, the car weighs in around 3280# with driver and has done best backed-up ET's of 9.49 @ 148mph on only 35psi of boost with very gentle 60-foots in the 1.5-second range testing the current setup for suspension dial-in and 2-step dial-in as I am trying out a very tall 1st gear assembly (2.571 Ratio).  Best 1/8th MPH to date has been 132mph on 45psi on a partial run.  The car does consistent 1.40-1.50 second 60's with gentle launches.

The current engine/turbocharger setup has been run from 2008- 2014 seasons with consistent 9.9-10.0's @ 145-148mph on 30psi on 93-octane.  The car is now on Race Components Inc (AFI) 2200cc high-impedence primary fuel injectors and 1000cc high-impedence secondary fuel injectors and running on E85 or E85/C16 mix.
