So, jump forward. My 914 -6 conversion now has its 4th motor and can move under its own power. Planning on driving from Denver to Salt lake for RRC.

About 5 years ago I decided to jump into the 914 world. I have several 911 engines needing projects and roller 911's have become really expensive ( and I have two 911 rollers that are already planed projects) so I bought a 914 for a -6 conversion. Not knowing much at the time I got lucky with pretty rust free 73.
It has kind of become my engine mule. First engine was a 2.4 MFI motor with S pistons and Ecams. Used it to decide if I like 914's, I do.

Mule as it looks now.

Ended up selling that motor to another 914 world member in Florida.

My friend (who will be joining me at Red Rocks, also shares the same name) also had engines that needed to be built.
So with the engine bay empty we built a 2.7 RS+ engine with RS pistons and Mod S cams and weber carbs. This was a big step up. Dyno below of 2.4 E with S cams vs 2.7 RS+.

We are working to get his 76 911 travel capable but if he is too soft for no AC he will bring his 01 turbo (you can give him crap).

His 2.7 made my 914 much more fun. I had a 2.7 engine in planning for "my 914" that this helped solidify the specs.

Since I jumped into the 914 world I started looking for "my 914" project to build how I wanted based on my experience so far. This resulted in having 4 914's at one point.

One of the cars I purchased sent me down a side road. It was originally a sad neglected car with great potential. I purchased it thinking it would make a great start for "my 914-6" but was ultimately too nice for me to modify so I spent a year and a half bringing it back to good health. It was purchased by another 914 member and should be at RRC as well. Story hear.

So after my friends engine vacated my cars engine bay I decided to build what I called my "junk yard dog" motor. This was built from parts I had that had no home. While not in new spec they were not yet worn out. They consisted of a 2.4 case that I used my new mill to add case savers and deck ( it was quite warped in this area). It was built to similar spec to the first engine, 2.4 with JE pistons 9.5 to 1 and E cams. It had T heads ported to S specs and ran Zenith TIN carbs instead of MFI from first engine. Made great power with the larger ports and a little more compression compared to stock port size MFI engine I originally built.

So ended up purchasing a bunch of 914 and 911 parts early this winter. This included a mostly ready to build motor plus a spare 2.7. About the same time I saw a post from some one with a 912 that wanted a complete 911 motor. Why not sell the "junk yard dog", I had a good 6 months until RRC why not make my 914 immobile again (IMG:style_emoticons/default/smile.gif) I would have plenty of time to build another engine.

Too be continued

See you at RRC one way or another.

Too continue. Parts purchase included two 911 engines. One was a 2.7 that had a small fire but was pretty complete and the other was a 2.4 the original parts owner was planning to use to build for a 914-6 conversion. They ended up not doing the -6 conversion and installing a Subaru motor instead.
So the 2.4 motor parts included a 2.4 case with all the machine work done. line hone, decking, oil bypass, inserts and shuffle pin.

Also came with a set of 2.4 heads that were rebuilt and twin plugged (along with valve covers). I set the heads aside to use on my future twin plug 2.7 for my other 914-6 conversion.

Also included new nikasil 86mm cylinders and JE pistons. So building a 2.5 long stroke. Came with good SC oil pump and all the engine tin.
I sent the crank from the 2.7 out for Mag and polish. Then I started trying to source some parts. I decided to use a set of 2.4 CIS T heads I had and planned to port them like my previous motor as they made good power. Started checking with the Porsche machine shops and most were 6 to 9 months out for work. I had to change plans to meet time deadline and decided to do some of the work my self and use local machine shop for rest.

Had difficulty sourcing vale guides do to supply chain issues. Same with bushings for rods. Time was slipping away with delays in getting parts.
I was able to source NOS bushings of ebay from someone who had a stash. Finally found valve guides. Sourced AA rod bearings from local parts distributor and rockers and Wrightwood gasket set from Supertec. Things were coming together. Build plan: 2.5L with single plug and 9.5 to 1. heads ported to S spec, MOD s cams, rebuilt Zenith carbs on PMO manifolds. Heads and rods went to local machine shop at end of May. Pistons would need to be machined for 9.5 compression as originally 10.5. It was starting to Looking like it might happen.
