May 1, 200916 yr needing some experienced wisdom here...my 87 ea82t is running great, but does anyone know which turbo exactly can i upgrade to that will "bolt-in" and not cost me a fortune? I also do not want to blow my head gaskets with too much boost, so i am intercooled and have b.o.v. w/ manual dump...HELP!? thanks;-]
May 1, 200916 yr Author if i installed a td04 turbo, does this mount right up to the stock flanges and coolant lines are all the same, or close? needing advise from the guys who have already done this.
May 1, 200916 yr Wont find much in this forum, you need to look in Retrofitting. http://www.ultimatesubaru.org/forum/showthread.php?t=88249&highlight=TD04
May 1, 200916 yr I saw a Cummins turbo laying on the side of the road the other day. Should have nabbed it for you.
May 1, 200916 yr The short answer is there are no direct bolt-in applications. At the least you will have to change the turbine discharge flange completely and modify the turbine inlet flange. The compressor discharge will change from pointing at 12 o-clock to either 1:30 or 3:00 depending on which turbo you switch out to. The compressor inlet will change with the US market TD's or is similar if not identical with the VF-11 or the JDM TD05-16G..... Modifying the EA82T's though is almost an excersise in futility. You won't get where you want to go without redesigned heads, o-ringing the block, and a custom head stud set. The cost of just those items far outweighs the cost of installing a newer, better performing engine. GD
May 2, 200916 yr Putting a TD04 on an ea82 isnt the end of the world I guess... You can buy td04 flanges, and they are very similar to the ea82 uppipe flange. Some people like to "ovalize" the rear hole and make a smaller bolt work or something. You can also just buy plasma cut/water cut flanges that have the td04 pattern. What I did was just use longer exhaust studs for the two front holes that line up perfectly, and then for the rear hole I cut a lttle bit off the original uppipe, and when I welded the flange right over the original flange, I left room for a bolt to just come up thru the bottom. Intake side can be interesting.. For what I was already working on with the front mount intercooler etc, leaving the original clocking for the TD04 worked fine, and all I had to do was raise the throttle cable mount. With enough help from an exhaust shop and http://www.silicone intakes.com, you can squeeze something in there that will reach the turbo inlet KEEP IN MIND!!!, ANY LATE MODEL SUBARU TURBO UPGRADE, YOU MUST INSTALL SOMETHING TO CONTROL THE BOOST IF YOU WANT ANYTHING ABOVE 6 LBS! (took us a long time to figure that one out, haha) EJ motors electronically control the boost with a pulse width modulated duty solenoid, and the wastegate by itself is set to only 6 psi. We just installed a manual boost controller (ebay cheapo) to bump up to around 11psi
