first time here so bare with me. 😁

 

I recently purchased a v3 Impreza.the ej20 was rebuilt with a vf28 when I bought it.the car goes great,and fast.but,I'm looking at getting a t3/60-1..now my question is,would it be wise to get new forged internals for the ej20 or move up to an ej25? if so will a long block fit?or would I have to get a short block.would I have to relocate engine mounts? any advice would be appreciated just looking for realistic answers before I start building.

Long Block vs short block do not refer to the 'size'

 

Short block is the Block itself including Pistons and without ancillaries like intake or even the Heads I believe 

 

ej20 and 2j25 are the same size, sorry thats about as much help as i can be sorry, not that good under the hood

Your kind of all over the show a bit but here goes...

 

1. Jokers spot on

2. ej20-25 will all bolt right in to the bay but having the right bolt ons is key. Hence short block (Block without bolt ons) vs. Long block (block with manifolds, Heads etc.)

3. When putting a bigger turbo in consider three things that need to work in unison ECU, Injectors and AFM(If your not deleting it).

Bigger turbo means you will probably need bigger injectors to keep up, bigger injectors mean better (tunable or flashable) ecu to keep up. Remember X PSI on a VF28 is not necessarily equal to X PSI on a different turbo. A smaller turbo will flow less at X PSI a bigger one more at X PSI. The more air a turbo flows the more fuel the engine needs to keep its S*** in order. For example 18 PSI on a v5 with Yellow injectors and a VF22 = Fun times 18 PSI on a GTX3071 and yellow injectors on the same car will have issues pretty darn quick.

 

As soon as you start getting into the realms of retunable ECUs on earlier models forged internals is recommended IMO.

 

Bottom line, If its fast as it is and you dont have a big arse stack of cash burning a hole in your pocket just enjoy it and do something when it shits the bed. Not before. In the meantime stick about, ask questions and do some reading :)

      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
