I was just given a SVX 3.3 motor, complete with harness and FI. Has anyone used this version in their 914? Since it's free, it's a good one but, is it a good match up for the car?
If I use it for one of the 914's, I will rebuild it completely first, I'm not sure what I would need for the conversion.
I know there's more than one thread here on Subaru engines, just trying to wrap my head around what will be required and what the level of effort is.
My thought would be to buy a good roller, install flares if they are not already there and then drop it into that.
I guess the first question is, has anyone here used this motor before?

I’ve got one also.. but still missing a few parts (IMG:style_emoticons/default/headbang.gif) . Seems to be a descent match for a 914 but the trunk may or may not need to be cut.

Doesn’t need to be cut.

I have been running one for 8 years. Great engine, great match for the car. You may not need to rebuild the engine. They’re pretty bulletproof.

Oh my bad - thought that depended on the intake configuration used.

You are right. I should say it probably doesn’t need to be cut. There have been some nice conversions done with the SVX. I bought mine in a running car with a bad trans for $500. That also gave me the main harness that I sent out for $550 to get converted to work in the 914. I’m using the stock ecu. The engine bay shelf was already cut out of my chassis so it made it a no brainer to do a water cooled car. The 5 speed trans was another couple hundred dollars. It’s not a “cheap” conversion but it’s still many thousands less than a Porsche engine and 915 trans.

The downside is there is less support for these engine and I see less of them for sale on Craigslist, etc. If my engine doesn’t last, I will probably move to a turbo four but that’s not something I will worry about until I have too.

Thanks everyone! This sounds promising.
@mepstein I'll check out your post(s)
@Chris_H Not 100% sure but, for free, I would think there's something wrong with it. (IMG:style_emoticons/default/smile.gif) The rebuild couldn't hurt anything, I wouldn't think.
Not sure if it I will put it into my 74 or get a new one yet but, I'm liking what I'm hearing.

They're known to be used in water cooled Vanagons too.
There's a video of a very healthy one on YouTube

I've got an EG33 too, and have flipped the intake. Bit of extra work to do it that way, but I didn't want to hack into things if it wasn't truly necessary.

I have acquired just about everything for the swap over the past few years, but I also acquired two children during that time and a job that has me overseas a ton, but I plan on starting the swap this winter.

I'll echo everyone else's sentiment - the EG33 is a really strong engine and yours may not need a rebuild. However, getting parts for them, including seal kits is getting more difficult.

I highly recommend Jeff Robenolt to do your harness work for you. I started doing it myself, but it turns out that $600 or so was some of the best money I've spent. Jeff is a genius and a really nice guy to boot.

Jeff did mine a couple years ago and I’ve recommended him to others with good success.
He mostly does VW vans but had no problem making the adjustments for a 914.

Start looking for a Suby 5 speed manual trans.

You'll really like it. If I had to buy a Subaru 6 today it would be the EZ30 but getting an EG33 free is great. I'm very familiar with the engine and all sensors, wiring, etc. so start a build thread when you're ready and we can chime in. There are a few substitute parts that are much cheaper if needed. I've been meaning to update my build thread with what worked and what didn't. Maybe this will get me motivated.

Here's a short clip of mine:

@mepstein can it work with the standard 914 transmission?

Yes. You need an adaptor. Everyone who installs a suby trans says it's almost as important as the engine. It you use the stock trans, the cv joints may not hold up. It's a slippery slope but everything i've read says it's worth doing. Mine's not done yet so talk with the experts.

@mmichalik

I have the adaptor plate, clutch, pressure plate and starter for sale if you decide to use the original transmission. Will make you a deal.
