EJ20X vs EJ20Y

Recommended Posts

Hi all, new here,

 

Anyone know if there are any major differences between the EJ20X and EJ20Y model. Apart from the obvious, that the X is coupled with auto transmission, Y with manual. 

 

Have an EJ20X engine and looking at installing into a manual transmission legacy, keeping within the 4th Gen legacy for simplicity. 

 

Haven’t found much on the web, most information seems to suggest they are the same. 

 

Any info would be appreciated,

 

Thanks

As far as my research that I did when I bought my bp5 with an ej20x I concluded there was no difference other then turbos.

Looks like you can do a direct swap from all that info. 

 

You'll have a higher compression ratio, so more responsive off boost, and more power on boost.

 

It will be more prone to knock,  so use good fuel and be careful how much boost you put into it.

Also another question, the EJ20X I have is coupled with a VF44, if I were to install this on a pre-facelift (03-06) legacy, whose auto transmissions had a VF38 originally, would the ECU require a re-flash for the VF44 or as its all factory should it be fine?

 

 

Read somewhere, that some kiwi people have swapped from a VF38 upto VF44 no issues but couldn’t find info if the ECU needed to be modified.

At a guess the turbo size difference and the difference in CR will be handled within the envelope of safety that the factor ECU provides.

You can always put it on a dyno to check... worst case you will have to flash the ecu to correct or install a simple piggy back ECU.

Can confirm both compression ratios are the same. Some say the X has a forged crank and rods but i personally haven’t seen that. As for turbo swaps plenty have been swapped but personally id re flash it anyways as the stock maps arent great as they are. Mine has been re flashed and it makes a massive difference even with very very minor mods.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
