Hello everyone,
I’ve started a new build Speedster, while I’m waiting for parts I thought I would post about my build. I think my build is going to take a while, I live in Calgary, Canada, getting hold of parts is not that easy.
I hope my post will help someone else in the future when they eventually take the plunge.
Here is where I am at.
As you can see, lots to do. The pan has been shortened by the good folk at Legacy Speed and Body:
The pan is from a 1969 built, 1970 registered beetle with IRS, it’s in pretty good condition, will only find out any hidden gems when it is sand blasted, for now though it looks okay. I haven’t got the shell yet, I used the instructions and measurements from the Fiberfab build manual I also got in contact with Vintage motorcars and asked if the dimensions from Fiberfab would fit one of their bodies, they confirmed that it would. I will be buying a shell from them eventually.
I decided to go with Subaru EJ25 engine. I just want to point out that there are a lot of dishonest people out there selling “good used engines”. My particular engine is an EJ251, that apparently had less than 100k km’s on the clock. When I stripped it down, here is what I found in the oil pan:
Yes, you are looking at the no3 con rod bearing. In case you are not aware, these engines are prone to what is called rod knock, which appears to be caused by oil starvation. The no 3 con rod was also bent.
I was in a bit of a dilemma, I could buy a Japanese Domestic model engine and swap the manifolds, the timing gears and some of the sensors are different in North American Subarus, but it was still a risk as who was to say the engine didn’t suffer the same issue. I could buy a new engine, would probably cost around 10k, Outfront motorsports have a good selection and a good reputation.
In the end I decided to go with rebuilding the engine myself, I would learn lots about the engine as I am building, if it goes wrong, it’s my own fault.
I took the engine case halves to a machine shop, this in itself turns out to be frought with danger. I had the cylinders bored out to 0.020 oversize compared against DNJ 0.020 oversize pistons which I provided, also had the deck skimmed.The engine was filthy, It came out of a ca. 2000 subaru Forrester. I asked the machine shop to hot tank and clean the halves, I thought they would be immaculate when I picked them up, how wrong I was. They had cleaned them, but had then painted them silver, but over all the dirt and corrosion and helpfully had also painted all the mating sufaces for oil and water pumps etc. When I got them home, I bought a load of different sized rifle cleaning brushes and rods and set about scrubbing the engine inside and out, I then cleaned the bores with ATF until no dirt showed. My advice would be to get the block Vapor Honed before you take it to the machine shop.
I have ordered a new crankshaft and connecting rods and bearings, FYI Naturally Aspirated subaru con rods are slightly longer than those in a turbo engine. You can see the bearings and pistons on the table, went with King standard size bearings.
Here is one half of the block after cleaning.
I’ll continue in the next post.
