A look Bechtech's Twin Turbo WRX

- Bechtech Automotive is a local shop that we have been working with for a few years now, and they definitely have a reputation and ability to tackle any tough project of build that someone can come up with.
The owner Colin has a WRX that he has been working on for years now, and a while back, he came in because he decided that he wanted to try something different with his turbo configuration. His main goals were to try to improve the usable power over the current turbo that he had, but he really wanted to try something custom and unique. We talked through some options, and in the end Colin settled on giving a twin-turbo build a try.
It took a little while, but the car is up and running now, and it is such a unique build that we had to bring Colin in to take us through the process, and see how he has managed to get his twin-turbo WRX to work.
Thanks for watching!

Broken down it makes complete sense! Especially with that split header setup . 💪🏽💪🏽 dope rex
Thanks very much! Stay Tuned!
“A look “. 🤔Yup I guess that’s exactly what it was to.. got me good
I love the uniqueness of this build for sure!! Always great to see people try new things and push the envelope.
Thanks for the comment and thanks for watching!
Sick build
Thanks FlatironsTuning, killer video, asked all the questions i wanted answers to! So happy I subscribed
Thanks for watching and glad that you liked the video.
Stay Tuned!
Yo I've been a fan since like day one I've spent a subscriber since you had only like five hundred people I'm from Colorado I live in ColoradoI've built several cars I love the channel and all the content super educational this build was super awesome and very different you have the right idea the channel to grow very big but you got to make it a little bit more Hands-On you've got to got to show us how it sounds show us around the car a little bit but great work keep up the new style videos and your channel should blow up much love keep putting out the new great style content !!!!🔥
Thanks for the comment, and Stay Tuned!
Thank you for showing the Dyno graph comparisons. It appears this twin turbo setup greatly increases daily driveability and overall linear power delivery!
Thanks for the comment! It is definitely interesting. From this point, if Bechtech does decide to go with the next turbo size up, we are going to be really interested in how the dyno chart is effected, and what the spool characteristics are as well.
Thanks for watching, and Stay Tuned!
awesome content here!!!
thank you. keep it up
Thanks for the comment and Stay Tuned!
How could you not let us hear it!? Mean.
Sorry!
Honestly, when the car came in, we just went to work on getting set-up, etc., and it wasn't until I started editing that I realized that I didn't get any footage of the car running.
Might have to work on that.
FWIW, it doesn't sound like any Subaru, that is for sure.
Thanks for watching and Stay Tuned!
Love your content and great build love it
Thanks Andrew! Stay Tuned!
Like the channel , learned a few things watching over the last few year's , please do a video on tuning Subaru's !
Thanks for watching Bruce, and thanks for the suggestion.
Stay Tuned!
So, hear me out. If the process of fitting twin-turbos to a 4cyl such as the ej257, would it be possible to bore out the stock displacement? What are the bounds of boring when you have a sleeve? If you could SOMEHOW bore an ej25 to 3.0, would it be able to spool some more power out with bigger turbos? Or is it all an "in theory thing" as subarus are temperamental
Thanks for your question. You don't need to bore the 2.5 liter block if you wanted to put on 2 turbos. But certainly as displacement goes down, you will have to pick a smaller turbo to get it to spool up quickly, and that can have an impact on peak power.
Adding displacement will allow the turbo to spool sooner, no matter if you have 1 turbo or 2.
The limit for the 4-cylinder EJ blocks seems to be about 2.7 liters. I think that you would be really hard pressed to go beyond that. But that gets so complicated.
I hope this helps, and Stay Tuned!
What was the main power output I couldn't find it on the dyno sheet maybe I'm just not reading it right or blind lol
Thanks for the question. The car made right at 400 whp. Pretty much the same peak power on both turbo set-ups.
Any idea at what rpm positive boost comes in?
Thanks for your question. I believe that the positive boost pressure comes in around 3,500 rpm.
Thanks for watching and Stay Tuned!
Desperately wanted to see a pull..
anyone running with a bottom mount single turbo? i also want to run short manifold runners as possible on my ej207
That can be done, and you would need to use a similar aproach to this one. The 2010 Legacy GT had a front mount turbo on the EJ engine FWIW.

@@FlatironsTuning but nobody has done it on a subaru, maybe a few that i dont know of but is that a worthless set thats why nobody runs them? those brz's and 86 are running them kits
@@alitoroganan2442 It is because of the large amount of complexity that you run into to get it to work properly. A local shop did the work on an Outback XT a while ago, and it was somewhat better than the result that you would get with a stock location turbo, but it just wasn't enough to justify the extra work needed.
In short, I'd say that unless you can do all of the fab work yourself, a custom turbo option like this is typically not going to be worth the expense compared to a proven stock location option.
But if you want to do something different and out of the box, something like this twin-turbo set-up can be pretty interesting for sure.
It all comes down to what your goals are, what your ability to do the work is, and what your budget is.
Hope that helps!
Unique setup! But I'll stick with my gt30
what rpms would you hit full boost
@@alitoroganan2442 About 4500rpm...this is on a ej20 so a little laggy..and makes 430awhp @23psi
@@simplesubie8248 what turbo location
@@alitoroganan2442 Stock bolt on location. It's the ATP gt3076r...almost bought a gt35 but way to laggy on the 2.0l
@@simplesubie8248 anything done to the block?
Stop ruining subarus by slamming them with big wheels, they are made to be fast AND agile.
Unique? Yes
Better performing? Arguably
Simple and practical? Hah!
Thanks for watching and Stay Tuned!
Pfi tuned this car
No it was tuned by Harvey at The Boostcreep.
Thanks for watching!
Good lord those taillights are fugly!
Nomenclature wars brah. That’s all it is. I dread the what’s it got in it crap! Line em up and the the score board talk. I hide my stuff that’s what we do in racing
