I love seeing people develop products like this for our cars. Good for Rasant!!

Well, it’s been awhile, so thought a progress pic was in order. Lots of little sub projects to get to this point; wiring, drilling, grinding, cutting, etc. Currently checking the throttle linkage, next will be fuel hoses.

Very cool car and excellent project. Keep it coming! John/CT

Well, the end of Phase 2 is complete, that is the installation phase. I decided to not change the intake manifold studs to the longer ones used with the phenolic isolation blocks as the studs were really being stubborn and the thought of breaking one of those off didn’t thrill me. I did try heat and had a stud remove socket but the first one I tried didn’t budge. So, I ordered three sets of intake manifold gaskets to shim up the intake manifolds to get clearance above the shroud, this left plenty of thread for the 12mm wrench size nuts and wave washers sourced from Belmetric. Per Al’s suggestion, I applied a thin coat of 574 to the gasket mating surfaces.



I decided to mount the AEM 506 ECU and circular connector of the Rasant Mil-Spec harness up on the firewall, just couldn’t see getting that pretty connector all dirty down below.



Still have some tidying up, but that will come after the fuel and ignition checkout, and first start attempt.

Congratulations....pivotal moment in the process and no better feeling than turning the key and hearing that engine fire up. Sounds great!

sounds sweet!

Starts like a Camry, and I mean that as a serious compliment.
Will you tune this yourself, dialing it in with a laptop, or send it to a dyno tuner?
Much appreciated, John

[Knockdown]

Thanks Al! Yours and Andrew’s kit and your technical support make this a fun project! Sure is nice having a laptop displaying all the pertinent info.

The plan John is to get as close as possible and then maybe fine tune on a dyno at some point.

First drive out on the road today, boy did that feel nice! Had some issues with crank timing errors while cranking the motor. Cleaned the ground strap connection to chassis up by the gearbox and that helped a bit. Also set the resync on missing crank triggers to ignore on the diagnostic page in the wizard, seems to be starting reliably now. Let the tuning begin!

Congrats mate

Sounds fantastic. You have done a great job. I have a '76 and I am about to get serious really soon with the same set up as you. Just a quick question - did you relocate the fuel pump from the LH wheel are to the later location up front? I am not sure if it is required and if the high pressure pump will be ok that far from the tank.

[Knockdown]

Thanks! My 77 has the fuel pump up front near the cross member. I pulled the fuel pump relay up front and connected the new fuel pump relay in the engine compartment to the fuel pump circuit that powered some of the CIS stuff. The wire size was a bit marginal but should be ok. Red/white wire in the engine bay if memory serves me correctly.

Nice to see this project coming together and.....the sharing of info.

One of the nicest aspects of transitioning to EFI is the information gathered up during logging. Here is just a small portion of the data logged during the first run primarily just to see if the sensors are behaving as expected. The AEMdata program makes this even more accessible since I can transfer the log file to my desktop PC in the den and peruse the timeline.

Hi,

Do you happen to have a ballpark estimate for what this setup ended up costing?

Thanks,

[75 911s]

Nice work! I look forward to doing this project myself.

[Knockdown]

It ran around $9k with the hi-rel harness from Rasant, which BTW, is really nice.

Duane, the car is transformed, really has come alive.

Just a quick question - did you still retain the original '77 tach and what was involve in getting it working with your new set up?
