  1. Hi all, I'm looking at rebuilding my first ever engine. The engine is an EJ20Y from a 2007 legacy GT wagon with approx 180,000kms. The main reason for this rebuild is to replace all bearings and rings to breathe many more kms and reliability into this engine as i plan to tune it with light mods (decat, intake, fuel pump and boost solenoid). I'm really chasing longevity and reliability and not necessarily high power thus why I want new bearings as they will probably go within the next 50,000kms, my last EJ spun its guts at 220,000. Question time. Q1. What is everyone's opinions on whether or not it's worth upgrading rods/pistons with just the light stage 1+ mods. I don't want to break the bank on this one, its my first build and 50% of this job is just for my own knowledge and experience! Will I get any gains from upgrading the rods/pistons while I'm still only using the stock turbo and stock tiny BP/BL intercooler? Q2. I don't think I have the budget to upgrade both the rods and pistons so which of these two parts in a EJ20Y/X is the weakest and more in need of upgrading? What parts do you recommend? I was looking at these. https://www.possumbournemotorsport.com/k1-technologies-subaru-ej20-25-h-beam-connecting-r Q2 continued. its worth noting that the previous owner ran this car on 91 octane for a decent amount of time and it ran like s***. I should expect potential cracked pistons and damaged ring lands. even if they appear okay would you replace them due to the high stress they have been subjected to? Q4. What are some good factory replacement rods/pistons? should I consider some internals from a EJ207 or 257? Q5. What rebuild kit is best? should I go to the dealership and get a OEM rebuild kit? I'm quite interested in some decent ACL race series bearings. so I could get a OEM rebuild kit and use ACL race series bearings. what are everyone's thoughts? what have you had good experiences with? what about head gaskets lol? Q6. Is the factory oil pump sufficient? I've heard of many people upgrading to a 12mm oil pump? is this a good idea or is the factory one sufficient? will a aftermarket oil pump bother my AVCS solenoids? Q7. its important that all of this rebuild will work with the factory tune/ecu as I have to travel 450km to my tuner. lets say i installed lower comp pistons from another Subaru engine, would i be safe to baby the vehicle 450km? (Nelson to Christchurch) I'm preparing for my first ever build here so any opinions are much appreciated. Thanks for your time
  2. 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
