Factory Information

All 1G cars have a 16 gallon (60 liter) tank.

All 2G cars have a 17 gallon (64 liter) tank.

he following table is a generalization of factory oil specifications for DSMs. Requirements vary with driving conditions and exact year of vehicle. NT is non-turbo, T is turbo.

The factory recommends a mixture of water and antifreeze, with the coolant comprising 30%-60% of the total mix. Higher concentrations of coolant are more suitable for low-temperature operation, since the "coolant" is actually antifreeze and anti-corrosion agents. Straight water usually cools the best, but doesn't provide protection against rust or freezing.

If in doubt, run a 50-50 mix of antifreeze and coolant. This is suitable for most driving conditions in the United States and Canada.

The following table lists the factory coolant capacities for DSMs. NT is non-turbo, T is turbo.

IMPORTANT:  Water cools better than antifreeze, but anti freeze will raise the boiling point of water and provide lubrication to the water pump.  Many SUMMER ONLY DSMs use 100% water and WaterWetter. There is debate wether this is enough lubricant for the water pump. If your DSM will see cold storage (freezing temps), ensure you have antifreeze in the system or you risk blowing out freeze plugs or cracking your block as the water turns to ice and expands.

1G cars have a stock boost pressure of 8-12 psi.

2G cars have 10-15 psi.

The service manual allows lower pressures, but those are rarely seen in actual vehicles.

The Last Word: People once thought the 2G 2L NT had 190 cc injectors, but according to Nathan Cross (moderator of 2GNT.com) they're actually 235 cc. Also, 2G autos were incorrectly listed as 390cc, while in actuality all turbo 2Gs have 450cc injectors regardless of drivetrain. [Thanks, Nathan!]

Fuel pressures given below are at curb idle. 1G numbers are as follows: the first number is stock; the second number is with the fuel pressure regulator vacuum hose disconnected and plugged. 2G numbers are with everything connected.

Paint codes can be found on the vehicle information code plate in the engine compartment. It is located on the firewall (underneath the windshield). The body color code is the bottom number on the plate.

Comparing the car to another car with a known paint code might not be a good idea - there have been reports that the paint codes differ across the years. However, for 1990, the paint codes were as follows:

The coefficient of drag for most DSMs is reportedly around 0.29-0.30. This applies to both 1G and 2G.

Table 2: 1995-1999 Talon, Eclipse and Eclipse Spyder 

Table 3: 1996-1999 Eclipse Spyder 

Different transmissions are not interchangeable. Note that 2G transmissions are interchangeable with 1G transmissions of the same model number, but 2G transmissions have different internals and are generally considered to operate much better. Usually only minor modifications are required to fit a 2G transmission to a 1G engine

Tranny gear ratios for DSMs

Full Read Here: http://vfaq.com/mods/Trannies.html

Excerpt: According to the Shop Manual CD, here are the gear ratios for 1G NTs, 1G/2G FWDs, 1G/2G AWDs, 2G 2.4 Spyders, Galant GSXes (GGSX, AWD nonturbo) and Galant VR4s. The Shop Manuals for the different years sometimes conflicted with the Tech Manual (the CD only has the early Tech Manual, so only covers 1Gs), so I put what I thought were the proper numbers in some places - thanks to Mike at RRE for corrections. I have put the Galant GSX in the Turbo section to make it easy to compare with the GVR4 and EVO GVR4.

The following table lists the approximate weights. Weights vary from year to year and according to which options are present on the car. Where two numbers are given, the first is for manual transmission cars, and the second is for automatic transmission cars.

Table 1: Approximate curb weight of DSM models (pounds)

The following table lists approximate weights for the various wheels.

1G DSMs have a recommended torque of 90-110 ft/lbs.

Leon Reitman ran his 4G63 AWD Eagle Summit to 12.04 on a 14B turbo, which is pretty darn good and most likely close to 300WHP.

Here is Leon Reitman's 12.6 Run  

Others have similarily achieved low 12s. Actual HP numbers unavailable.

Looks like I scooped up this info just in time. Columbus DSM website no longer exists.
