I have questions for our 914world Subaru Gurus.

I acquired this EZ30R conversion last year. Kent’s (76-914) @76-914 subaru conversion has always impressed me, so it’s his fault.

Anyhow, 914 ran well but had an intermittent short that ate up batteries. I decided to paint the exterior of the car before tackling short. Once, painted, Noel and Bruce helped me one Sat with 5 lug conversion.
My goal was to get the short figured out and move the harness and battery bank to the engine bay.

Short of time, and my lack of Subaru knowledge I spoke with Outfront motorsports
https://www.outfrontmotorsports.com/ into helping me get things right. ( And only 5 min from home)
One week later I’m absolutely stunned on what they accomplished. Lots of upgrades to fuel and cooling systems, a new ECU wire harness relocated to engine bay. There is a detailed list of things I’m forgetting that I will post later. In a nut shell, Dyno shows 272 HP with 223HP to wheels. I got a test drive last night and I was totally floored. Super smooth and responsive. I can’t wait to pick it up this afternoon.

Is this a typical HP range for this engine?

Rev limited to 7500 rpm? Is this ok?

Can’t wait to address trunk paint next.

Your thoughts..photos coming.

BTW…The new wire harness is now 75% smaller and tight…super professional
Bonus, my rear trunk is free on any modifications or loose wiring.

Your thoughts please

Oscar

During the test drive yesterday my fingers were crossed my recent 5 lug conversion wouldn't fall apart.

What a way to shake this beast down.

The guys at Outfront have been a joy to work with.

I've now nicknamed this beast "Garfield"

Looks like an awesome car! Would love to see the detailed list of what’s been done. I’m in the middle on an EZ30R conversion on my car and did talk to Outfront about ECU options, so I would love to know what’s in your car. I think these late-gen motors are rated at 240hp, so your 272 sounds great. The redline is higher than the stock motor I think (maybe 6800 stock), so again 7500 seems really good. It was one thing that I wished was higher when I was making my decision, so I’m glad to hear Outfront seems comfortable with that redline increase.

I would also be interested in knowing whether your car has drive-by-wire throttle and whether the variable cam timing is still in place (the feature is run through solenoids on each bank). Must be a fun car!

You are just teasing us. 914s respond very well to that kind of power. (IMG:style_emoticons/default/w00t.gif)

Super nice Oscar. Watch out; you may find yourself driving rather than towing to events. (IMG:style_emoticons/default/biggrin.gif) I've seen similar numbers on a D model and attributed that to better engine breathing. These engines were originally choked down with 12ft of exhaust. I'm curious which models will produce the most HP when installed in a 914. Since yours was just tuned by "THE Suby Voice of SoCal" I'm going to bet yours is faster than one built by a plumber. (IMG:style_emoticons/default/lol-2.gif) Question; are you experiencing any Rev Hang with the DBW system? I wanted to join your drive this weekend but I'm out of state currently.

Nice one Oscar, is there any other place for the battery available? If I built another one today I would throw the T4 out and go Subaru six for sure. My only reason for keeping the T4 in the Martini build was to be able to participate in the local P club autocross events and those have grown into a boring mass of only new cars now.

Best $$$ I’ve spent in a long while.

John and Brian from Outfront motorsports went over and beyond.

I’ll provide a thorough update soon, going to be a busy weekend.

Even though I have a 6 in mine now, I'm somewhat envious of the subie eng. Oscar how come the PC925 didn't make it in the red optima spot? When people catch their eye on my PC680, they can't believe that tiny bat is up to the task, but it has been flawless.

Good eye (IMG:style_emoticons/default/biggrin.gif)

That PC925 is DEAD, will relocate a new one to the engine bay soon.

The Intake was turned 180 deg before I took it.

That way no cutting was required to trunk

Good observation

It looks great and it is about the same why I want to go. I will stay with the 4 x 130 wheels but I will see. I will go with the Subaru MT5. How do you like the power ? Does it have the a custom motor cradle or is it a a Coldwater ?
Thanks.

I love the power but probably won't use it much.

The exhuast note is awesome

Here's a photo of cradle...not detailed yet
