can anyone tell me is a wrx ra engine the same as a wrx engine? my ra has a 5th injector where as my wrx doesn't? does the ra have bigger injectors or turbo or anything?

 

The RA has a closed deck block,which are stronger,same turbo(TD05),same injectors(380's),same power,different ecu with higher rev limit(7500),the fith injector doesn't actually do anything,it's their for the rally teams to use,you should have intercooler spray,and short ratio box.

 

what so my 95 wrx will be fitted with a td05 turbo too? i thought imprezas had td04 turbos??

when i tried to get a turbo thru my work the company we deal with said imprezas only have td04 turbos fitted which is y i thought the turbo in my ra was upgraded at some point but its on its last leg

 

The early imprezas had the td05,then changed to the td04 later.The wagons had the td04 in the early years to.

 

All the early WRX's had cdb's, it wasnt just the RA's.
No other real difference, the fifth injector did nothing on the car, ecu is the same, the STi was different though, engine was the same but gearbox ratio's are different, think this was the same for the WRX's (shorter ratio gearbox that is).

Think your getting a little confused there
JDM cars started off with the TD05, the wagons on the TD04, that all changed about 1996/1997 time, UK wagons (early ones) acutally had the TD05 turbo, weird eh!

Were the wrx different to the uk classics? My 95 uk had open deck.Aso,the ecu must have a different map as the RA revs higher?
