      Question 16T turbo upgrade 2.5t

      Hello everyone, my turbo recently blew up on my 2.5t and I heard a 16t is the optimal upgrade for the 2.5t. My question is, can I hook up a 16t from a 2.3t without any modifications? I heard about differently angeled flanges and I want to make sure that I will not run into any issues regarding fitment and connections.

      2003 and later 16Ts have the same oil and cooling connections as the 14Ts.

      don't forget to swap out the OTE pipe also. there's one in the classifieds right now (not mine)

      The coupler is also a little different.

      I'm the current owner of that OTE and a set of blue injectors. PM me with an offer. You can run with your oranges but if they're sloppy you could run into engine damaging trouble. Swapping to blues gives you piece of mind but a tune would be mandatory to use the blues. If I were going to use oranges I would get mine cleaned and flow tested before putting on the turbo. Any low flow numbers and I would replace the injector. You're running with little to no reserve duty cycle on the oranges.

      Without a tune you'll see faster ramp up to power and power holding into the upper RPM bands but the computer is going to fight to keep you at stock levels. To really make use of the turbo a tune is a must. The faster ramp up is where the danger lurks. Sloppy oranges plus a fast ramp up that the stock tune can't handle will threaten the engine.

      Make sure the boost regulator and turbo control valve are in tip top condition. I would run a stock pressure spring in the TCV. I would also replace all of the vacuum lines and replace the turbo boost pressure valve with a new volvo branded unit. Off brand solenoids are not worth the risk and old hardware is inviting disaster. Stay away from ebay "new" turbos as well. Total junk.

      Installing with oranges and no tune would run between 650 and 850.00 if you can get a cheap 16t and rebuild it. add 600 to 1000 for a tune.

      Didn't learn from the 2005s repair bills and brought home a second. I'm a glutton for punishment I guess

      Exhaust downpipe flange is the same. As covered above the water and oil lines are the same for all Mitsubishi 2003+ turbos (14t and 16t), the intake from the maf to the turbo is the same. You will need a different OTE pipe because of the neck on the 16t being shorter than the 14t. Coupler should be the same but earlier turbos have a very nice multi layer silicon coupler that can e used. Tune and fueling upgrades are recommended to maximized however it is safe to run it as is, me7 is load demand engine management and will only make the boost/load it requires. The benefit with stock maps is that the 16t is so much of a larger turbo (in comparison, they’re still pretty small as turbos go) that it’s incredibly efficient at the lower boost levels an XC runs so you will be making a lot of flow and much much less heat compared to the 14t.

      for those that have done the swap, two questions:

      -how hard is it to remove solely from the top?

      -are there any gaskets or washers that automatically need to be replaced with install?

      Thanks

      Easy.

      Manifold to turbo gasket, turbo to downpipe gasket. 6x 11994 washers (2 each banjo bolt), turbo return drain upper seal and lower o ring.

      You’ll need an earlier (and larger) over the engine charge pipe but that’s easily sourced and bolts on.
