After weeks of delays due to shop and family commitments as well as part incompatibility issues, Josh was finally able to finish the engine build that he started several weeks ago. None too soon I might add since it is getting down to the wire on this project!!
One of the issues we had was when I ordered a ring set, TWICE, I was sent the wrong oil control rings. Each time, causing a week or more in delays. . . Man was it nice to get those cylinders on and the motor finished. Here are a few shots of Josh back at it getting the cylinders prepped and heads on and torqued.
After we determined our rocker geometry and made adjustments via shims and push rod length, Josh got down to making the custom length chromoly push rods. He did a fantastic job!!
He then was able to get the modified 1.7L rockers w/ OEM Porsche 911 adjusters installed and the valves adjusted.
We’re going to start the motor with these bolt-on covers. Yeah, yeah, I know; they will probably leak, but we gotta try ‘em anyway since they’re easy to change out for stockers. . .
Before the engine tins went on, we set the air gap at the hall sensor and 36-1 trigger wheel to 3mm and verified a good signal with a multimeter. We wanted to do this now since getting at it later will be “fun”.
Then began the job of the engine tins. We robbed these off the old 2056cc and cleaned them-up.
After that, we mounted the ITBs and synced the linkage, which only took about 30 seconds (try syncing any other type of linkage that fast).
Then I had Josh break out the torch and anneal the copper exhaust gaskets so they would be butter-soft for good stub sealing.
After they cooled, he installed them into the ports, anti-seized the studs and mounted the custom stubs using OEM Porsche 914 2.0L exhaust nuts.
Below is a shot of Josh and his first motor build. I’m really proud of him and what he has created here.
Today, I had to make an exhaust hanger just before the V-band. With the 911 muffler, this is not needed, but if I run a straight pipe like at Bonneville, it will need to be supported. This is what I came up with.
Then we got the header on and the muffler installed.
