2.7 CIS, Another six conversion Options

[John]

I tried searching, but didn't get much.

What is involved with fitting a 2.7 with CIS in a 914? I can figure out the plumbing and the electrical, but I believe that I had read long ago that it was a PITA to fit CIS without cutting anything or perhaps a mixture of different parts could be used or parts of the intake could be relocated in order to get it all to fit. I'd prefer to avoid cutting this 914 engine compartment since I'm trying to make this one appear mostly factory. Any advice or better yet pictures would be appreciated.

I'd rather not go with carbs, since I believe that I'd need to swap cams and pistons in order to do it right.

This one is only going to be a fun street car (I already have a dedicated track car)

(All my conversion experience has been with 3.2s, but I have this body, and I have this engine...)


Thanks in advance!

Started cutting the holes and they turned out well so far, have a couple left once I come to grips with how I want to do the oil return line to the tank.



The rubber sleeve for the filter console fits the hole I cut nicely. Do the hard rubber/plastic insulation washers meet through the hole? In other words, do the mounting holes need to be large enough that the stepped mounting washers go through the holes?



While I like the DW Design filler neck, I wish the screw-on cap looked more like the 914-6 oil fill cap. I may find a donor stock looking cap to modify. I found that the oil filler neck that I thought I had is actually from a 911 and doesn't properly fit the oil tank opening.



As I'm doing this, I'm wondering about how I will plumb this car. In the past, I've had front mount oil coolers and tanks. I've run the return line from the engine case up front to a thermostat then cooler then back to thermostat, then oil filter, then to tank. I've never plumbed in a pressure relief valve in the external oil cooler circuit. I've noticed that in all the 914-6 GT cars, a pressure relief valve in addition to a thermostat is used. I'm not 100% convinced that I really need the pressure relief valve, but why would they have put them in the GT cars? In air cooled 911 street cars, they simply put a thermostat in the lines leading to/from the front mounted coolers.

Any thoughts on the pressure relief valves plumbed into the GT cars? Anyone actually use a pressure relief valve in the lines to the external oil cooler?






I have decided to relocate the engine lid release latch to the passenger side.

I'll keep plugging away at this.
