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!

I did this in 1987 with a 2.4L CIS engine. I did not need to cut up the engine bay or rotate the injection system in any direction.

1. I moved the engine lid latch assembly from the Driver's side to the Passenger side of the engine bay to make room for the CIS (requires some spot welds and making a longer release cable). The engine lid is designed for the latch pin assembly to be mounted on Driver's or Passenger side, so I moved it to the Passenger side on my original lid(again a couple of spot welds involved). Many years later, when I ordered a GT Lid from PCA7GGR, I had Sergio perform the same modification to the GT Lid before he painted it.

2. I relocated a CIS item from the rear-top of the CIS assembly (I think an altitude compensation part, has 3 hoses attached to it) to below the CIS assembly. I attached it to the lower part of the #6 intake manifold.

3. I replaced the fuel fitting on the back of the CIS Fuel Distributor. The original fitting came straight out of the FD directly into the rear firewall, so I replaced it with a welded up 90 degree banjo fitting.

4. I used the Becker Engineering 6-conversion mount at the time (1987). I will be switching that out this year (2019) for the Naro Mount, so that I can install the MB911 Heat Exchangers I bought a couple of years ago.

I like the thought of leaving most of the CIS as is. Does that car still use a stock air filter? (I know it is a 2.4 and mine is a 2.7, but they should be similar) I'm going to have to get off my butt and pull the big dent and get this project moving forward. I suppose I will bolt a trans onto the engine and see what it looks like jacked up into position. I could easily move the engine lid latch and release mech to the passenger side. The franken-tub is cleaner than I remembered. The guy in Mason City did claim it was a CA car, but it has (2) two 76/76 front fenders and front panel on it.

I would suggest you look at this thread: http://www.914world.com/bbs2/index.php?sho...engine&st=0

Pictures of the setup are on page 2.

This is a CIS install, using an VW GTI airbox and some fittings. It doesn't require you to remove the engine lid latch or modify the engine compartment.

I looked at the thread and it is interesting. I can't find what airbox was used in that example, nor could I find the elbow that attaches to the throttle valve. In a similar thread, I read that DrEvil simply rotated the fuel distributor 60 degrees and things cleared, but I couldn't find a picture of that. The other problem I see with an airbox like in the thread that you referred to, is that it appears access to the air filter would be less than ideal. Do you know who pieced that system together?

When I helped him out, the car was already like that. I do know the airbox was off a VW GTI, and I think the hose was too. The fuel distributor was from the 911, but it bolts to the airbox with no issues.

Changing the air filter is easy, just raise up the fuel distributor assembly. There is enough length in the hoses to allow it.
