Upgrade BOV for V1/2 ej20g?

Recommended Posts

Hi all 

 

I am a noob and do want to replace my (broken) factory bov with one such as a hks ssqv or V6 sti I believe it's an HKS unit. 

 

However the problem is that my turbo inlet which is on the early wrxs uses a hose rather than a flange to the turbo-intercooler pipe. I don't run the factory pipe rather I use radiator/silicon Hose as mine broke. To fix this, would I either have to get some silicon Hose, drill a hole to fit flange? Or is it best to buy a factory hose?

Don't suppose you have a pic of how yours currently looks?

 

GFB do BPV’s with a bunch of different bases that will most likely work over your hose as long as it is a common size.

Thanks for that, I see that a lot of later ej20s have intercooler mounted bovs as standard. The flange is welded on to the TMIC? 

 

I guess that's not really an option for me, so I'll have to find a turbo-intercooler pipe that has a hose fitting to accept mount... Or just drill a hole and bolt in which will be rugged... 

 

But anyway are the hks knock offs legal? I thought vent to atmosphere was illegal?

Bov can vent where ever since it’s just compressed air

wastegates have to be plumbed back as that’s exhaust gas cos well cats and noise laws

 

You can get the later model flange like on the intercooler to a pipe fitting but not much point. Just find one you like the sound of and fit it to the existing pipe. Not sure how much needs to be recirculating to not have issues on the older cars. Newer ones run 100% atmosphere without issue

      Hi everyone,
       
      Does anyone have insights on the maintenance and reliability of aftermarket alloy radiators? I am thinking whether or not they will give any sort of advantage when one is touring remotely, where reliability of the cooling system is a must.
       
      Since modern cars have plastic radiator tank tops and, of course, they will degrade over time. Has anyone installed an aftermarket radiator, particularly ones that are sold her locally, and has had a good run with them so far?
       
      My default will always be genuine parts all the time but it would be nice to get some opinions and experiences on this topic. Cheers.

      What is this project?
      Its an engine build with a discussion and details about options and trade offs building an engine. Hopefully heaps of photos and video. 
       
      Why?
      Because I couldn’t find the details I wanted online in one place and heaps of builds leave out the discussion on why they picked the parts and what flow on effects it makes.
      Plus after @Joker posted about Facebook YouTube take over I saw a motor and it seemed like a good idea at the time.
       
      Whats with the name?
      It came for a PM from @PBMS as the base engine for this is a EJ207 W block with a suspected cracked piston that on one has looked at yet. Until it’s opened there’s no idea on what’s inside.
       
      When does it start?
      It started March 2019. 
       
      Where is it?
      it will be in this topic mostly and across Possum Bourne MS YouTube etc.
      before the engine is assembled I hope to video in 4K all the parts and write up the reasoning behind each 
       
      How long?
      over the next few months
      since the engine is a donor the cars stays on the road.
       
      Whats the plan?
      Build a great motor with well through your part selection. 
      Everything is pretty much open to ideas as things are added to the list. 
       
      Initial thoughts are:
      - build it for around 800hp (was 600hp) and then street it about 500whp.
      - Stay 2.0 as the cost of stroking it is higher and I can’t seem to own a car that won’t rev out to at least 8,000 rpm 
      - CNC the heads since it isn’t that much
      - Cams around 264 but has dual AVCS so maybe bigger, but needs to be streetable
      - close deck maybe depends on block condition

      new here, 
       
      but wandering if anyone knows a decent place to either get a angine refurbished or where to get a standard refurb kit for a ej203 for a 2003 bp5 liberty wagon. 
      it currently has 380xxx kms on the clock and is showing its ware and tear. just wanna refurb for now and turbo convert later next year if i can swing it. my baby girl is gonna get some love and care as the last owner didnt maintain her at all
