WRX Ver 4 motor into RS Legacy 1991

Featured Replies

Hi Guys and Girls,

 

Just new to this site,

 

I was wondering if it is possible to fit a Ver 4 WRX motor to a 1991 Facelift Legacy RS as the block is still an EJ20T, Will I need to change the Diff and gearbox as well ?????, I have blowen the Compression rings and can get the new motor really cheap but want to know if all the extra work will cost to much

 

Thanks

I believe you might, *might*, have to swap the wiring harness over as well....

 

but if you take the long block of the WRX engine...and put all the Legacy stuff on it...it should work fine...
