Another 3.0ltr 914 project Options

[alan9144]

Ok, I was swithering whether I should go Subaru or 911 when a 3.0ltr sc came up at (I hope!) a good price, complete with loom, ecu, tank, cooler etc. So I bought it, decision made.

Wont get it for a few weeks so I have been immersing myself in old posts on the subject and think the following is the bits and pieces I need to do.

1. Fabricate mount bar
2. Reverse CIS intake to fit in engine bay
3. Modify Gear linkage
4. Fit oil tank and cooler (can a 911 tank be used?)
5. Fabricate exhaust
6. Wire up electrics
7. connect fuel supply & return
8. Move engine lid catch
9. Fire up and go for a blast (wishful thinking probably) (IMG:style_emoticons/default/happy11.gif)

Have I missed anything out?

You don't NEED to reverse the intake to fit into the engine bay. It will fit, installed exactly as it did in the 911. Clearance is snug, and the engine lid will probably rest on the snorkel, but it can be done.

CIS will require new plumbing, with a different fuel pump. You should replace all of the fuel lines, ideally.

You'll need a new flywheel to mate an SC engine to the 901 gearbox. The SC expects to bolt up to a 915 with a completely different clutch mechanism. The 901 expects the early "cup type" 911 flywheel. The SC uses a 9-bolt crank, where the earlier engines used a 6-bolt crank, so you can't just install an early (pre-'70) 911 flywheel to make the swap, as you can on anything up to a 2.7. The usual way this is done is a custom flywheel is constructed by taking an early flywheel and replacing the center section with that from an SC flywheel, which is obviously not a DIY job unless you have a full machine shop to hand, and really know how to use it. If you can't find a local engineer to make one of these for you, Kennedy Engineered Products can make it, though shipping it to Scotland would probably cost a bundle.

If you're constructing your own mount, making one matching the pattern that Rich Johnson uses for his firewall mount is really the best bet. The mounts that bolt to the /4 mounting points work, but often have more clearance problems with the shift linkage and exhaust.
