RRE's 1G/2G Eclipse Turbo Upgrades

Mitsubishi TDO5-16G Turbo Upgrade

This turbo is made by Mitsubishi Heavy Industries. The TDO5-16G with the 7 cm exhaust housing will hold over 20 pounds of boost if you ask it to. If you promise to keep the boost down you can use the stock fuel system other than an upgraded fuel pump. To use it's full potential however, you will need at least 550cc injectors and some form of electronics to control them. The stock 1G turbo flows 405 cfm vs. the 16G at 505 cfm. With the proper porting of the exhaust manifold, Turbo, and O2 sensor housing, you will hardly notice any increased lag. You will however feel tons of top end power!

MHI EVO III 16G Turbo

This is the stock turbo from the Lancer EVO III. Outwardly they look like any other 16G. They use the same compressor housing, TDO-5 exhaust wheel, and the same 7cm volume exhaust housing. Until you pop off the compressor housing... HELLO! Big Wheel. Flows 550 cfm vs. 505 cfm for the regular 16G.

The normal 16-G compressor wheel is 1.83" at the inducer and 2.36" at the exducer. The Big 16-G is 1.89" at the inducer and 2.68" at the exducer. That is just over 5/16" (8mm) larger than the normal 16-G exducer and the same size as the GReddy 18-G (inducer diameter is only .10" smaller than a 18-G). Direct bolt on for 1G cars, you need a standard 16-G Install Kit for 2G cars.

Sorry, we do not offer clipping on EVO III Big 16G turbo

 

With a 2nd generation Eclipse, the stock Garret T-25 turbo is so small that it's a joke. Putting a larger turbo on will make the single largest performance increase. A TDO5-16G requires an installation kit for the 2G since the intercooler piping comes off from the top instead of the bottom. The kit also includes the necessary oil and water lines and gaskets Turbo Warranty Information

Pricing Note 12/2011

Our supplier just told us our current _cost_ on the 16G series turbo is $1470. At this price (and even at half of that) they are not worth the money. Maybe all the chinese copies ate into the orders enough that the volume dropped off? Maybe some international market politics are involved? Who knows. We used to be able to sell these things for $500 and make a little money on them. For obvious reasons for now, forget about these. Shop around a bit, maybe someone has new old stock. Just be sure you are getting genuine MHI parts if you are paying real money for one. Chinese copies can be had for about $225.

EVO III Exhaust Manifolds/ O2 Housings

EVO III Exhaust Manifold:
These have the same runner diameter as the 2G exhaust manifolds but they have the larger collector that matches the larger inlet to a 16G with a 7cm exhaust housing. They do save a lot of time porting however. They are a direct bolt on for a 2G, they require the same slight trimming on one corner when used on a 1G to clear the P/S bracket as a 2G manifold would need.

EVO III O2 Housing:
These are BIG. They have a larger inlet hole for the turbine flow, larger wastegate passage, and a larger outlet. The bolt spacing on the outlet flange is wider, this makes easier to adapt a  custom 3" down pipe. They have a slightly different angle at the DP flange. If you already have a 2.5" DP with a slotted flange, it is _possible_ to bolt it up to an EVO O2 housing. Usually it will stress the flex section too much so it should be considered a temporary solution only. We include a larger flange and also the larger inlet and DP gaskets with the O2 housing to make things easier for you.
