So begins another project for me. I tend to only build the wild and crazy stuff, as everything else tends to bore me these days. I've been working on this one for a while already, but it was finally time this week to move it into the clean room, and begin the first mock up assembly of the short block.
The engine started life as a 1990 C2 964 base with 40K miles. While this beast is based from a 964, it won't be finding its way back into a 964, or any 911 variant. It will be fitted into a very special Beck GTS (904), and because of this, the engine will have several unique twists. Externally it will look much more like a vintage 911 engine, and I am making special preparations to the crankcase, and all hardware to help the engine better fit the character of the car. All the hardware has been yellow zinc plated, and the crankcase has been dulled and cleared a bit to have a consistency more like a vintage engine would have. A resin fan shroud will be fitted, and instead of the engine ancillaries being cluttered with EFI components, atop this engine will sit a pair of very large, and highly modified PMO carburetors. Ignition will be via direct fire, so the absence of a distributor won't look very vintage, but it will remain clean. Internally I have retained an OEM 3.6 crankshaft, but all other internals have been addressed with overkill engineering from A to Z. You will find the approach that I have taken to the modifications to be a bit unconventional. Pushing a car that will weigh in wet @ 1800 pounds, the engine combination requires quite a bit of alteration, and the addition of carburetors to this engine further changes up the engine combination. Why not EFI? I'll answer that question before its even asked! It boils down to simplicity, a vintage feel, and what fits the character of the car more than anything. The 904 GTS is an ultimate platform for this beast. No doubt! Fully dressed it weighs 1800 pounds. Here is the Facebook page for the vehicle build up: https://www.facebook.com/BeckRaby-41L-GTS-B...6244547/?ref=hl Len is still finishing the head work, so I'll likely build the bottom end, then have a bit of a break before I end up finishing assembly. The heads should hit the flow bench in 3 weeks. I have two more similar builds to this one planned over the winter. One of them will be for my recently completed 964, and the other will be for an RSR clone. Both of these will be EFI versions. The engine being built for my 964 will be a high torque configuration. Here are the first round of photos, as I began mock up assembly, and finished ultrasonically cleaning the block, after soda blasting it. Other photos will follow, as I finish the engine.

Auto Verde billet oil pump, but I decided not to use the pump, and rather go with a 996TT pump.

These pistons will see skirt coatings, ring land coatings, and thermal barrier coatings after they are balanced, fitted and modified.

Mocked up the 996TT oil pump with the intermediate shaft, and needed to do slight clearance work to make it just right. Took the time to disassemble and true the layshaft/ chain sprockets. Now I'm ready to dynamically balance the rotating, and reciprocating masses, which I will do on Monday. Then it's time to move forward with short block assembly.

Now that is the country boy way to pull the engine!! I am sure they would be spinning backwards at the Ferrari factory.

If they hook a generator to Enzo's body, they could power all of Rome! (IMG:style_emoticons/default/biggrin.gif)
Thanks for the 964 engine pictures. That is the future for my car. I just need to find the 964 engine. |
