questions: 4speed d/r in a impreza

Featured Replies

I have this idea rolling around and had a few questions.

 

I have a 4 speed d/r in my brat that im parting, and had a idea about putting it into my 2.2 impreza.

 

What is the final drive of the brat?

can I take the axles to the machine shop so that I can mate the impreza axles to the 4 speed d/r trans?

does anybody know if the brat drive shaft is the correct lenght?

 

I know that I will have to use

(1)the brat rear diff

(2)adapter plate and flywheel for the ea-ej

(3) fab up a trans cross member

(4) and .... answers to the questions above

 

any discussion on the matter is helpful, its all speculation for the moment

so i found a thread where this is discussed, sorry I will post this questions there but...

 

he is using a 5 speed. is my 4 speed any different other than have a 5th gear?

The 4spd is a lot longer than the 5 spd, and not as strong. Not really worth it IMO

when it comes to subaru trans strength, for me anyways, its all relative.

 

if there were problems with the 4sp d/r trans being "weak" we wouldn't have as many successful ej22 running bigger than stock tires as there are on this site

 

thanks for the info on the 4 speed being longer, tho

right now Im planning a 4 speed dual range swap into a '93 Impreza that has a 3.90 rear diff and 1.8

 

from my research, im going to need,

1) ej/ea adapter plate

2) reworked ea flywheel to match ej crank (according to numbchuxconversion write-up on the ej22 swap )

3) xt6 pressure plate with nissan 720 clutch release bearing (according to numbchuxconversion write-up on the ej22 swap )

4) lengthen/shorten drive shaft(depending on what the length of the 4sp is)

5) custom trans cross member

6) put 25 spline stubs in the ea trans or use the fwd impreza axles that have 23 spline inners

I've done 2 EJ swaps into 4spd cars.

 

Both of them the 4spd died within a year. (one horribly blown up front diff)

 

Get a 5spd. It's REALLY not worth all the effort to swap in a 4spd.

 

Espescially if you only go with the 200 MM clutch, you will be slipping clutch all the time.

 

Trust us.

 

 

Get a 5spd D/R

Thank you!! There are many stories of issues with the strength of the 4 spd.
