ej15 turbo help?

1. Open door

2. Place turbo in vehicle

3. Drive down road making "whizz pish" noises

But really, you\'re far better off selling it and buying one that Mr. Fuji and his team of well-paid engineers already attached a turbo on to.

May also be in a country where a WRX or STi is a much pricier option than they are here too

I would assume that most parts from EJ20 will fit EJ15 just fine?

So manifold & turbo (just go for TD04)

Probably want the injectors from same year WRX - decent fuel pump - ECU can most likely be re-flashed to suit - oil feed just tees off the oil pressure sender, drain is simply tapping the sump (or using an EJ20T one?) - budget for an intercooler and thats your basics covered at least

Could be back-yarded pretty easily and cheaply - done properly, it would be ultimately cheaper to source a front cut and transplant a complete motor OR better yet just buying a complete car altogether and not faffing around with +Ting this one (but who knows what your situation is)

Run on low boost (under 10psi) it would probably be fine, most motors are happy to take that *if tuned to suit* and it would wake the little critter up. Think of it same vein as turbocharging a small SRXX or 4GXX motor or what have you, if the parts from the turbo motor do bolt up then you\'re onto a winner, bear in mind it\'s not going to go setting any speed records but will still be enough for a giggle

yea Mike more info on your motorvation please :P

just for fun/skid hack go for it, run 6psi or less/wastegate pressure from an old rs/GT turbo (vf8/10)

on road legally? dont bother OR open ya wallet for a sti/6 speed/monstor conversion

So I have a Subaru Impreza 2004 ej15 and need a bit of help on what I need to put a turbo in it.

Any help would be nice thank you :)

An exhaust manifold, downpipe and an ECU.

Probably need to find an oil feed and somewhere to drain the oil to.

It\'s a project I was thinking of doing for on road purpose. Just a turbed ej15. If it isn\'t road legal then I won\'t bother. I\'m unsure of a lot of things to do with this an that\'s why I asked for help, like things I need? What I need to know? Is it possible? And also can I drive it on the road being an ej15t or not? My car is a 2004 model impreza 1500cc. Not a wrx.

Any help?

Thank you

Only way to find out is to get the manifolds/turbo/intake/oil feeds/waterfeeds/ and see if they bolt on, u will also need bigger injectors,airflow metre, and ecu.

After all this is added/modified tuned and running then you will need to take it in for a Cert, this will probably bring up other issues like the need for bigger brakes and rims to suit.

I hate shitting on someones idea but mate it sounds like a truckload of hassle for very little return unless you plan on doing all the work yourself. Even then it seems like a ton of work for not a lot of reward and no real additional resale value.

Similar to the Supercharged Legacy floating about a while back.

could easy spend a lazy $15k turbo\'ing a EJ15, then you still only have a $1000 car

harsh reality sux eh

sweet question and asking all the right ones too! does sound like a fun wee project, heck I\'d do it just to piss everyone off too if I had a spare car/coin

I\'m currently in the process of doing the exact same thing, EJ15 with forged bottom end and a bp twin scroll turbo, if you can do everything yourself it is manageable but if it\'s something you have not done before it just won\'t work.

You will most likely end up spending lots of money and then end up selling the car and the parts for less than what the car is currently worth.

I think the problem is that some cars / motors lend themselves to having this done very easily, and some do not

SR and RB motors are prime examples - literally bolt on the turbo "bits", get an ECU to suit, twist the timing back a few degrees and you\'re away

To be fair *if* the bits like manifolds etc all bolted right on, then in theory you could have it all running for under a grand and be away with a little 160hp ish noise machine. There are thousands of boosted N/A motors around which live happily for years so long as things are kept sane

Bear in mind it would absolutely destroy any resale value for the car so I\'d steer away from it - if it was say an early 90\'s one then go for it, nothing to lose but time and money I spose

Out of curiosity where are you from and what\'s the situation? Would end up with a far more capable car if you just sold this and bought an earlier WRX

I\'m from Wellington. I bought the car from a car dealer in Lower Hutt, my situation is that I want to start a project and if anyone is from Wellington or in that region would you like to help out maybe with parts and a price or just some cheap deals going around that you could tell me about wether it be from a retail store to a second hand product.

Thank you all for posting. There has already been some tips I have taken in.

Well if its what you want to do, then go for gold!

I suggest you watch these: if you havent already (some good usefull info - same sort of boat you will be in)

Your shopping list has already been posted -

Turbo - td04 would be an ideal size

Oil feed lines and a return line

soopercooler ;) or any intercooler + standard subaru BOV

Headers and up pipe + downpipe (+ gaskets)

Then you need to figure out if it will run on your current ecu/afm/injectors safely

oh and then CERT

and a boost T lol

      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
