CPA/PCA - Hershey Swap Meet

The 2010 Porsche only swap meet held in Hershey, PA (yes, that Hershey) was again a great show. A bazillion P-cars were on display, as well as a large swap meet section of independent and commercial vendors such as FabSpeed, Transloggt, Rennline and Tangerine Racing with his neat T4 horizontal cooling system.

NA twin plug bad ass..

A 3.6 turbo - the sign says 'Rare & Awesome'...

Rennline 964

A few rarities such as this 959. One of 200 ever built. (note the matching bucket)

The factory detail on the exhaust system cannot be captured in a photo... also check out that side view mirror.

964 powered Beck 904. Can you say power to weight ratio?

Lots of 914 goodness...

Mock Fitting - Crank/Rods

All cross drilled oil passages must be free of all debris - even during the mock up stage. You don't want to scratch or embed anything in the bearing shells.

 
All bearings are Kolbenschmidt purchased from Pelican...

They only go in one way...

Don't be alarmed if the rod bearing sits a bit proud, they are a crush fit...

Lubro Moly for the rod bolts & nuts.

Apply to the male threads.

Assembled & torqued to spec...

RUF History

Ever heard of the CTR Yellow Bird? You should have...

Mock Fitting - Pistons/Pins/Rods

Here's some shots of the mock fitting for the rods, pins, & pistons...

Pistons Arrived!!

My new new Keith Black pistons arrived a few days ago. These are 96mm forged hypereutectic alloy with a 24mm wrist pin.







I bought these Hastings rings off ebay for a steal. A little known fact is the Hastings p/n 2C4203 used in Ford 4-cylinders are an exact match for a 96mm T4 piston.

Conn Rods

Here's a shot of the connecting rods I purchased from AirCooled.net.
They are for the 2.0 liter crank, polished & balanced but being they are factory types they weigh a ton :(




I modified them with the oil-squiter notch which delivers oil to the underside of the piston crown.

Chasing Threads

It's important to chase all the threads on the case. Chasing threads cleans out gunk & grit as well as removing minor imperfections in the threads. This results in a cleaner engine and better thread engagement.

Thread chasers can be difficult to find for metric threads, not to mention the high price you have to pay once you find them. So, being the cheapskate I am, I made a set of my own in about 10 minutes.

I started off with 10mm/1.50mm pitch, an 8mm/1.25mm pitch & a 6mm/1.00mm pitch steel socket-head cap screws with a class 12.9 rating. I stay away from SS bolts which could possibly gall the threads when used repeatedly.

With the trusty Dremel & a thin cut off wheel attached, just run up & down the length of the shaft - perpendicular to the threads. Make a few runs back & forth cutting thread depth.

You can make these for any thread, I made one for the head studs as well as the rocker adjusters.

The Start...

The start. Here is one side of the case I'll be working with. This is an 'EA' case from a 72-73 914. The case is in good shape, bearing saddles are clean, no scratches or wear. I will clean the outside with a DIY soda blaster.

The First Post

This is the first blog post of my Type 4 engine build process. The end goal is to throw this into a early '70's Porsche 914. I will be logging the build process here with photos and as much info as possible.
