Looks good, Ben! I'll be excited to see how a Subaru turbo engine conversion looks installed to your high standards.

Is that engine from a Legacy GT, WRX or a Forester XT? I'm assuming the Legacy GT is CAN interface but the older WRX and Forester platforms are not.

The intercooler will probably work in the stock location. I remember Tristar Eric just laid down the intercooler flat on his after trimming the bulkhead panel and reported excellent IA temps.

Keep us posted!

So this isn't the STI version right?
I believe Eric's Vanagon S was built with the STI motor.

Either way it will fly.

Yeah, any turbo Subaru engine in a Vanagon will fly. Vanagon S was actually just an early WRX EJ205 motor. But it was still good for less than 15 seconds in the 1/4 mile.

A factory red intake is an STI right?

Was the Tristar converted with one?

I thought there was a difference between the motors in a WRX and an STI WRX???

I recall the same thing from looking at pictures of Eric's install
of the bulkhead being trimmed.
I love the fact that Ben is doing a Subie turbo conversion. His installs
do look clean when done. Appearance is almost as important as
performance and reliability in my Vans. Keep up the great work Ben.

Yup, the red wrinkle finish on the intake manifold is an STI thing. Eric's Tristar does have an STI conversion in it hooked to a Porsche G50 transmission.

The STI in the US has always been a 2.5, whereas the regalar WRX was a 2.0 until 2006. The non-STI 2.5 has 230-250hp depending on the application.

I saw on your site that you are making a header for it? Are you changing the turbo location? I figured you would only need to make a downpipe.

Yeah, that's an XT or LGT motor, the STI is 300BHP. I came real close to parting out my old Legacy SS turbo to put the motor into my van...

VVT on one head only makes it a wrx (post 07) or xt. Given it is the small turbo outlet Id say XT. Super good choise! Great crank and the sti rods in there as well. Power is down lower than the Sti's , And you know in its first life the chance someone was reving the piss out of it are low!

We have endless hours into this 2.5 Turbo. It has a water to air intercooler and a external oil cooler. It will be run on stand alone too.

I have a 40k mile WRX motor sitting here. I made jigs for all these parts. I can do it again if anyone is interested.

Here are some pics.

Would I be correct in assuming that in a turbo application, it is not too important to tune the lengths of the exhaust pipes?

Yeah it doesn't matter. Getting from the head to the turbo as quick as possible is generally best.

Mmm.... why are you all talking about STI engine? Or wanting to know what car it's coming from (look at the link posted above and you will know).

My post is humble. Just sharing a new adventure. I already have an STI engine with over 400hp. It's sitting on a shelf, it's been there since 09 and it's ready for MY next personal van.

I have been dealing with Turbo engine all my life. Nothing new. Now, I want to make them reliable in a westy. I want to keep them stock as possible. I do like Rocky Mountain version but it won't be mine. To many modification to the turbo location and exhaust (don't take it wrong bro, I'm in the same business).

XT, WRX, STI, Legacy GT, Outback XT... Same stuff.

I have split open a few of those and the basic short block is all the same (picture to come). Intake, injection, air control, ECM is what make them somewhat different.

The one on the picture come from a Forester XT 2007 36,000km, 230hp in the us and 250 in Canada.

Harness: no can bus, no anti thief system. Semi CAN that can easily be cheated to analogical mode.

What you know about me/us is what I want you to know. The juicy detail you will never know about it.

By the way you funny guys, to make a turbo 250 HP into a 320hp take about 10 minutes.

That said, no VW transmission, drive train or axle will endure such power.

250hp is the red line.

I love you people, I have fun here and I'm willing to share a lot of stuff... but there is a limit on what I will share. I hope you understand. I need to eat.

The link above show part 1, I will post about part 2, 3 and 4.

Best regards gentlemen.

We mostly moved the Turbo because of the Syncro fuel tank. It will probably fit in the stock loaction it will just require a heat shield and such. Either way, it is a lot of work.

Keep it up Ben. I am excited to see the final product. I still haven't driven our 2.5 turbo conversion. We will finish it this spring.

Equal length runners are generally designed to promote the efficiency of the scavenging effect on an NA engine, but a boosted engine doesn't require this feature. Boosted inline engines can have a straight "log" and split heads like this can use unequal length runners and there's really no penalty in performance.

I know it was an XT!! The inereds of the 09 wrx and sti have a nitrated crank, and 11mm oil pump. XT's didnt get those. But they are all super engines.

Rockymountianwestys, Can i pouch the pic of your turbo and post it on the 914 world board? that would totaly fit the 914s.

Got it, I hate Syncro Smile Still, the exhaust you did is impressive!

Exhaust is the most challenging part of it Smile
I don't worry much about the inter-cooler location.

That customer as an automatic van.... yep, so I want to keep the exhaust somewhat stock. If not, he will destroy the transmission in a day or 2.

My neighbour just bought a 05 Legacy Outback XT, he keep bugging me to find him a nice Forester XT or Legacy H6 or GT/XT.

After trying a lot of version he fell in love with the Turbo version. Even if the H6 (3.0R) have about the same spec the turbo version is way more fun and peppy to drive. Feel like a German sedan (Audi, VW or even Mercedes). I drove it for an hour today, yep, it as guts, at 100mph and it feel like my Forester at 60mph. We push it once to 140mph.

worked on the harness today, not so different from the stock 2.5L... so far. What worries me is the fuel pump choice, I can't take the subi one.
I have the pump controller. Which one are you planing to use?

Cheers, Ben

The pump controler is a big part of the newer suby turbo engines. It runs different pressure under different boost. I think it verys the voltage to do so but i dont know for sure.

I would think it would be important to match the stock output under boost.
