Besides the interference problems the JDM twin turbo engines are very tough to get them to work properly. The origional car comes with a special programed ECU. There is also a black box controler controling the sequencial turbos. The system was susposed to spool up the primary turbo very quickly. But i understand there was a flat spot on the transsition. When I got mine I tried several ways to make it all work and I could never get more than five pounds of boost. I bought a turbo from a 2002 WRX and have been happy ever sence. I think the JDM twin turbo engines are over priced. They do have better heads and the cams have a higher lift and should produce more HP. Don

$$$ about $300 for MSnS and about $1200 for the Link. A freind has given me a map to get started with. Looking now for a wideband meter. The new MS version 3 board shows a lot of promise but MS is not plug-n-play. There needs more work on the EJxx series engines. If someone would write code for Subaru's uneven six tooth wheel things would be a lot easer. More suby fans need to bug them at the MS site then maybe someone there will help us out. I know nothing about the Xede system. Many of these after market ECU's require a tuner and some dyno work with dollars i don't have. Like I said if you want the 4EAT info PM me your email. I see they are letting me to post attachments if there is some interest I will start a new thread. Don

When I first put the EJ20/4EAT in I used a ECU and TCU from a EJ22 (about 115 wires to deal with). It ran but would not rev up. I decided it was in limp in mode. I don't know if the TCU would work as I never moved the car. I installed a stand alone Link ECU only seventeen wires and instant sucess. I had read someone was racing a 4EAT and shifting it full manual. I found out who it was but they would not share info about how. With a little info digging I discovered with the use of three diodes wired into the 4EAT wire connectors the tranny would stay in each gear until it was shifted again. Hacking the TCU is beyond me but I have thought around a paddle shifter. I thought mabe a racheting device on the gear selector actuated with a two way solenoid. Just a thought. Don BTW I am working on a Megasquirt n Spark for the car now........

The twin turbos were scraped soon after the car was finished. The car is multi-purpose. It sees use on the street, desert and sometimes the sand. Don

Subarubrat I am using a EJ20/4EAT in about the same config as your Lambo might use in a street legal sandrail. I am shifting the tranny full manual without the TCU. The linkage to shift it is very simple compared to five speed manual tranny. The only problem using it in a street car is the shift is very very firm and third gear is free wheeling. That could be taken care of with a togle switch and a timer/resister on the pressure solenoid. I have posted pics in the photo gallery. If you want more info PM me your email. Don

Another try. http://www.ultimatesubaru.org/photos/showphoto.php?photo=7410 The photo did not show up here but you can click on the link. I fill my quota in the Photo Gallery enjoy.

First photo try.

I could copy and paste info but there is a diagram included in the file and I am noy allowed to post attachments. PM me your email and I will send the information to you. Don

I don't know how to post pics or am not allowed.

I am new here but not to Subaru. I have been running a 97' twin turbo EJ20 with a manual shifted 4EAT auto tranny in a mid-engine street legal sand rail for three years. I am working on installing MegaSquirtnSpark on another EJ20G for another future sand rail. I am not sure what way to go with the MegaSquirt. I would like to keep the coil on plugs but it may be hard to do with EDIS. Any one here doing some thing along this route. BTW if anyone wants info on shifting a 4EAT full manual without the TCU let me know. Sandsuby
