1.7L to 2056 Options

[sreyemj]

I have a 1.7L motor in my project 914 that needs to be refreshed and I'm thinking of converting it to a 2056 at the same time. This is a somewhat budget build, I'm on a timeline to get it back on the road this summer and as a student there's no way I can justify buying a 9k kit. After looking through quite a few threads on the subject, I'm considering having the case line bored and checked by Tims ACVW in Kent, WA (or maybe there is someone else in Washington State I should consider?). I would prefer to assemble the engine myself if I have time (depending on the rest of the car), otherwise I'll have it assembled.

FAT/Rimco have a 2056 short block kit including pistons and cylinders for $1800 and 1.7L head exchange with 42x36mm valves for $1600. I'm not sure than includes opening the heads up for 96mm cylinders. The FC 442 camshaft looks to be more for carbs, I'm thinking I may want a different camshaft so I can stay with my stock D-jet. Anyone have any experience or input on the FAT/Rimco kit or heads? Is there another option I should consider at the price point?

You can do a 1911 and only need the 96mm P&C. 1.8L heads are a plus. Will work with the Djet with a little MPS tuning. Heck of a lot cheaper for not much less power. The real HP in a 2056 comes from the 2.0L heads.

I have no idea of the engine's history so I'm definitely going to be splitting the case. At that point you might as well do a 71mm crank and 2.0L rods. Will definitely need to address the heads, FAT/Rimco has several options that refurbish the 1.7L heads but I would like to hear from anyone that has gone that route. I think the 42x36mm valves are bigger than the stock 1.7L valves?

I had my 2L case line bored by John Slack in Olympia Wa. He purchased the new main bearings and did the new bores specifically around the size of these bearings. He also fly cut the cylinder base spigots, and had my crank re-ground to first undersize and did the conversion for tapped oil gallery plugs.
He rebuilds Rolls Royce aircraft engines and I was very impressed with his tooling.
He goes by "Jesco Reient" here

Great, I'll try getting in touch with him. Would be great to work with a member here.
