Default anyone through TT onto their ej25?

Got a sweet twin turbo set up and I am going to be installing it onto my Ej25 by the end of this month (hopefully before it starts snowing here). I was just wondering if anyone else has done this install, looking for tips/ pictures... Firstwork Ive done to a car

There was a twin turbo kit that came out from Forced Air Technologies but I don't know of anyone that actually bought it.

I believe AZScoobie ran the FAT TT setup waaayyyy back when.

The general consesus is that unless it is a show car...you will ultimately get better drivability, more power potential, and a LOT less problems from a good single turbo setup.

That is the reason why not many here if any at all at this point run one.

Now....there were factory 2.0L TT motors in the JDM market. But those setups will not fit on a LHD car at all. Besides....most of the pepole that drove them said they basically sucked anyway. (Dead spots etc.)

Mmmkaynoob?

no, Kastle ran the TT setup, but robert designed the header wrong so it didnt work correctly, oddly enough a subaru tuner didnt know the engine firing order......

Are you installing a Japanese old Legacy twin turbo setup? An imported 2.0 clip you bought? If so, thats why people are doubtful.

No no... No long block, buddy already used it. He sold me the turbos, heads, fuel injectors... everything but TMIC, gauge, boost controller, and the downpipes i gotta get custom made. Itll be going onto my currently NA USDM EJ25. I know the EJ25 isnt supposed to take turbo, thats why Im running such low boost (6psi). I know about the firewall issues with the whole motor and wouldnt be doing this if the price wasnt so good. It will be cool to have two turbos though

remember that the CR of the EJ25 is 9.7:1, not boost friendly. and it has all cast internals and an open-deck block design, but if you make sure that you dont get any detonation or lean conditoins you should be okay with just 6 psi. are you using a smaller turbo to boost a larger one, i.e. suquential?

Haha I was just talkin to my boss about sequential set ups... and came on here to ask if anyone knew if the Ej20tt was sequential or not...

Im like 95% sure it is, but I'm car retarded.

yea if you are talking about the old ej20g TT legacy setups, they are sequential. It is not really ideal, its hard to get to work smoothly together, as many people with them have talked about the valley of death being very bad, which is where one turbo transitions to the other.

Besides the fact that the JDM EJ20TT will not fit in a USDM LHD car.

Im not taking the whole engine... just the neccesary turbo parts. I did a bit of research on the "valley of death" as you call it, and I think itll be alright.

Ill be able to give better posts/info with pics next week when everything comes in

If you plan on doing all the work yourself and you've never done any work on a car before give yourself a good summer of long days to do this, or perhaps longer?

I'm not saying you won't be able to get it done quickly, I'm just saying with the amount of problems you'll likely run into and your lack of experience this will be quite a challenge.

And as everyone has already mentioned tech support on doing a twin turbo setup will be minimal, also what sort of engine management will you be running, and is there a local shop that will be able to tune it?

Also, mind telling us exactly what car you buddy was running this setup on, and why he wants to sell it?

Nick

PS - On a side note, I think its the v8 or v9 jdm engines... anyways one or both of them use a twinscroll setup and it is said to be very nice, so there is hope.

yes, I am aware it doesnt work, but he didnt ask that so just to clarify wallykincaid you will need to make a totally custom set of pipes for it to work the driver side turbo will run into the steering rack/column if you like totally custom setups, go for it, that is what I am doing, but its not for everyone.

Sko - I think if I do all my research for the next couple weeks, get everything lined up and labeled I can do this in a friday night, sat, and sun. I got all the tech support I need through the guy who sold it to me so Im not worried about that. Hes a genious at making awesome set ups work. EM is staying stock, its only 6 pounds of boost the car will run fine. The only tuning its going to require is a MBC so I can make sure i dont go over 6psi. I dont believe my buddy ever ran this setup, he got the engine and wanted the long block, so the rest is mine.

PHATsuby - I plan on getting a coupld custom downpipes made. Im not sure exactly where yet, but once I get the turbos in Ill start calling around. I dont know if theyre going to have to see them or what.

Ill be running my stock exhaust, at least for now, and stock clutch, cause it can hold 200HP. Im getting new injectors and all with the TT setup.

I know itll be a bitch to do. But Ill learn a lot and in the end Ill have a totally custom and unique TT Legacy.

Oh, another thing. What do I have to do to prep this? Ive read every post in this forum, I have a lot of information/theory but what do I have to do as far as fuel lines, the air box, fitment etc...

Default Are you sure about no EM?

I don't think it's wise to run this setup w/o some sort of EM. Going from N/A to FI is a lot to ask the stock ECU to compensate for. It may run, but it's definitely not going to run well.

I know you've said that you've done your research, but from some of the comments you've made, I think this is going to be a much more complicated project than you're planning for.

Either way, I wish you the best of luck! Keep us updated!

id hope hes using the stock ecu from the TT setup

guy seriously
you think ittle all come together
but it wont

i didnt used to believe people when theyd say multiply your goal time by 2-3, i thought horse **** ill get it done within 6-8 months

wrong

took me over a year and a half to get everything runable

i mean i didnt work on it 24/7, maybe if i were all pumped up on aderol i could but for a student w/ a 25 h/r week job, and a girlfriend (still liked spending time with the car more )...made things difficult
