How to Build the Subaru FA Engine for BIG Power!

In this week's video we are finally getting the chance to build an FA engine that was worth making a video about! See what we have to do to prepare this engine to support around 500 horsepower.

Thanks to Mike now i want to WPC treat even the spoons and forks of my home, the floor, the whole house, my wife, my dog, my friends... Everything now needs to be WPC treated and cryogenically treated 😂😂

I love that in the same video he talks about contrasting crystalline grain structure so intelligently and then some how says things like “makes ej’s go bye-bye” and “dead nuts balance” without losing any credibility. Fantastic video!

Japanese micro peening, lubricity, short stroke good thing I got my air pods in here at work 😂

When you start talking metallurgy it's magical. Great stuff.

I have zero intention to build out my VB WRX with the FA24 to this extent, but really enjoyed the in depth explanation of the engine’s pros and cons. I could listen to you explain how things work for hours. Really appreciate the time, energy and genuine enthusiasm for what you do.

[davewallace]

The level of knowledge, and the way to articulate what he does is totally amazing!!

[y.b.-]

It's the small, almost magical, trial and error results that Mike shares in these videos that is priceless for anyone looking to do things the right way while minimizing the F***up potential that are priceless.
Yes, the basics are the same regardless of the engine or the goals, but those things that wait you when trying to figure out what works and what not are the gold nuggets
Thanks Mike and MotoIQ team for sharing!

For informative purposes..
I paid 11k for my Rebuilt title 2016 WRX with 65k miles. I threw a bearing at 85k miles drove it until 100k ticking like a mf since I had a motor ready(I was getting -2FKL and -11FBK for a while cruising at under 15% throttle before it started to tick bad. But under WOT or stronger acceleration it would disappear and my AP would read zero sometimes a -2 or -4 on occasion which supposedly was acceptable) it was FBO minus manifold on a TMIC. I spent maybe 5-6kish for the upgrades? Was flex with lpfp/hpfp upgraded.
8K for a new P2P Closed deck Longblock 0 miles (costs 14k got lucky, I was going to buy a shortblock for 6k that same week) has everything done to it minus cams, 625+ rod bolt 1/2" headstuds etc
3k for STI Swap
2k for TR GTX29 turbo
7k for Misc parts & labor
1k for Ecutek software/tune
Limited to high mid 400 whp because of no secondary injection :c once I get that which is another 3kish I can do 510-520whp on my GTX29. I'll run what I have until end of year and get my secondary fueling and a BL58XR (Claims 770hp of airflow) biggest you can go stock location before you spend 6k+ on an ETS turbo kit.. or if I get lucky and find another ETS kit for 3k ill snag that. For those wondering, I am indeed broke as fuck and I finish concrete for a living.

I can't resist not to watch, It's pleasure and joy to listen and hope to build my FA-24 one day🙏🏼

What an absolute gem of a human, and video.
I just got a new-to-me 2018 WRX-Sport Tech a few months back, and this is the detail I was hoping I'd be able to find when I went looking for it.
Awesome.

As an owner of a new gr86 and new to the flat motor world, your videos are great and I can’t wait to be a customer.

[njx]

This guys' videos are my therapy!! 😊

[dewjustin]

Love the videos. An FA20 vs FA24 video would be awesome. I know a lot of people that are curious about the details and breakdown of the two and if/where the FA24 improved over the FA20.

[kamargee]

I love how this guy breaks stuff down. If you do too. Click that thumbs up. He deserves it

[timpeace]

I’ve landed in the future and can report back that Markiplier finishes his engineering degree and develops a love of Subarus!

[darkobelisk]

I want to see this guy build his ultimate engine and put it into production

[Ifixtheinternet]

Can all the manufacturers please watch this video and note all of this guy's concerns?
I want to see this guy designing his own engine.

[djosbun]

It’s easy to see that this gentleman grew up in a machine shop. A superbly detailed video! 👍🏼

This is an absolutely amazing and comprehensive video!! My 2015 wrx limited has 169k miles now and I'm really thinking about doing a full overhaul before something fails. This video was far better than any other Subaru engine video I've ever seen!!!

Some many positive things to say about how this presenter disseminates info I like on many different levels . Despite not being deep into understanding of engines I fully comprehended 99% of what was explained which shocked me . Excellent delivery, i could write a book on why . Subbing despite no need for services or any of the info on a deeper level but highly enjoyable to be able to have that level of uptake of info that I wouldnt expect to grasp at that level and the manner in which its done is excellent and if i was in need of services this video and presenters manner etc would grab me to dive deeper 100% . Excellent .
