B99Brighton Posted August 10, 2005 Share Posted August 10, 2005 I was wondering if any one out there has performed a swap involving the jdm motors? I was debating starting a swap but really don't know what to expect. I have a 99 brighton that might become the new home to a EJ20DETT motor from the JDM people. I was wanting to know what problems I might encounter with the wiring, transmissions, etc? How do i identify what chasiss number I have? Most of these engines are from a GB5 chasiss. Can't find anything on the vin plate that will tell me what I have. Any help would be helpful:slobber: Quote Link to comment Share on other sites More sharing options...
Subarutex Posted August 10, 2005 Share Posted August 10, 2005 EJ20DETT?? Sounds more like nissan engine than a subaru one. I believe the correct engine designation is EJ20H. Subaru does not use the T for turbo in their engine designations like a lot of other manufactures do. Quote Link to comment Share on other sites More sharing options...
NorthWet Posted August 10, 2005 Share Posted August 10, 2005 The twin-turbo JDM engine is designed for RHD, and is supposed to have interference problems with LHD steering column. Quote Link to comment Share on other sites More sharing options...

Any help would be helpful:slobber: 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.
