18g Cartridge????

[bsbllfit7]

So i was perusing on ebay and found that they had 18g turbo cartridges on there. I am under the understanding that you can put this cartridge into the compressor and exhaust housings of a 14b or 16g? Does anyone know anything about this. I have a blown 14b sitting around and if this actually works i would take the 18g cartridge and put it into the 14b. Also i would upgrade to the 7cm housing but as of now 6cm. Lets hear any stories about this working and how well it works. If its possible lets get some numbers as well!

As long as you're buying the 18G cartridge with the TD05H turbine, it will fit either the 6cm or 7cm TD05H turbine housing because the turbine wheels are the same between the 14B, 16G, 18G, and some 20G's. I do see they offer an 18G cartridge with a TD06SL2 turbine, this will not fit a 14B's 6cm or 16G's 7cm turbine housing.

Your compressor cover will require extensive machinework in order to mate to a 18G compressor.

This is not a direct bolt-on upgrade, if that's what you're asking.

what is the reasoning for the compressor cover needing to be machined? Is the wheel just bigger and wont fit in? Sorry if it sounds like a basic question just considering this. Also there is a kit with the compressor cover on there too. here is the link

Have you ever tried shoving a 3" pipe into a 2" hole?

Seems like too much money for a non-authentic Mitsubishi turbo. For less you could buy a complete brand new MHI Evo III 16G and not be stuck with a Taiwan turbo in a used turbine housing.

is the gains of the 18g not much different then an e316g? I havent really seen any compressor maps or anything like that. Just figured it would be a step above the 16g and a step below the 20g.

The difference between the Evo III and 18G would be like going from a Small 16G to a Big 16G. It would be barely noticeable unless you're maxing out an Evo III and looking for 1-2 lb/min of additonal airflow. Most don't feel it's worth the upgrade and skip right to the 20G.

Guys have successfully run them in the past, but the 18G compressor is unpopular enough that Forced Performance is discontinuing their 18G-6SL2 in favor of the new HTA68.

ok sounds about right to what ive been reading. If i went 20g route i would rather go with an hx35 or hx40. I saw that you have one in your AWD. What was install like for you and do you like that setup?

Um, there's an 8-10 lb/min gap between the 20G and HX35, and a 20-25 lb/min gap between the 20G and HX40. You're talking about HUGE differences in airflow and required supporting mods, here.

The car is not complete yet.

ya i know id need more fuel for that hx35 but the lower spool and better flow sounds great to me. next paycheck i have 880cc injectors on the way, 255lph fuel pump and a afpr. I will be getting keydiver for that setup so the supporting mods are pretty much completed for any of these turbos.
