BBR's 83GT - turbo 302.... now with EFI!

[Russell]

60's will support enough turbo to ruin the block, and yes, I said that. Keeping in mind there's a big fat fuel pump in there that doesn't have to stay at 40 something pounds for EFI... 60psi and 60's should be plenty to oil down the starting line. :|

I should mention that I think it will need heads to make enough to do any damage. I don't think it's current iteration will let it get hurt too bad.
Stay after that carb, it'll come around.

I am thinking E85 someday. I do think they will be close getting me where I want to be or a split block which ever one comes first. As soon as I feel like I am getting close to having it running I remember the 37-11 things it needs I have not done yet.

[BBR]

All along, I have been chasing this stutter as if it was a carburetion problem. So in order to rule out more variables, I put together a quickie Duraspark/HEI ignition like we used to run. Wired it up last night and it fired right up. This distributor has 20 degrees of mechanical advance so I set the base timing at 6 degrees. It should be fine for a a few laps around the test track (parking lot).

Prelim results: Interesting. I drove it around the parking lot a few times and it *maybe* still did it? However it did not seem nearly as pronounced as before. The test drive was kinda rushed because I had to be somewhere, so I think I will drive it more before passing final judgement.

[BBR]

Oh yeah, still does it. Drove it longer today and it definitely still has the stutter.

Stupid thing died on me about a 1/4 mile from the office. Battery was too weak to start it. Walked to the shop, got the work truck, came back, lit right off, drove to shop, walked back to work truck. Blah. I hate cars.

So, I pulled the HEI and Duraspark distributor back off and put it back the way it was. Sort of. I put it back, verified that it would start and run and then switched the codebase from TFI to MSnS (Megasquirt n Spark). Supposedly with the TFI codebase, the MS defaults to letting the TFI module set the dwell. I am only using the module as a pickup and my intent was to have the MS set the dwell. Not sure if it ever was or not but using the MSnS it definitely will. I switched that and it cranked up and worked. Seemed to idle better so maybe it is working better. Lol.

Seems like a lot of distributor problems for everyone lately ....

[BBR]

Seems to idle better, but pretty much runs the same. Starting to think more seriously about converting to EFI. I could continue to jack with this carb ad infinitum trying to make it run like EFI, or I could just use the Megasquirt that is already in the car to do it's thing. I have a stand alone EEC harness, the stuff to quickly make an EEC to MS adapter, 2 different 4bbl throttle bodies and injectors. The car has a return reg in it and so all I *really* need is a set of rails, a high pressure pump and a set of intake gaskets because I would have to pull the intake and drill the injector bungs.

The rub is that I would want it working properly by the Buick v. Ford shootout in October.

[BBR]

I pulled the stand alone harness out of the box, looked at it for a few minutes and realized the only things I really need to add are the tps, right and left bank injectors, and a coolant temp sensor. Literally 5 new connections to the MS. Haha.
Went home and found the wiring harness for the original BBR. I used it way back in 2008/2009 with the MS1 that is now in the yellow truck. It has everything I need with just a few extras. I'm beginning to wonder why I haven't already done this. Haha.

[BBR]

I took that harness and weeded out the stuff I didn't need and traced/labeled wires. Only took about 45 minutes.

[BBR]

Went up to the shop to start the harness install and ended up with the intake off the engine. Lol. It had to come off to drill the bungs but I wasn't expecting to do it today. Haha.

You never know when the "Gotta do it now" bug will bite.

[BBR]

Underhood wiring is all done. Gaskets are scraped. Bung holes and rail mount holes are marked on the intake. Fuel pressure gauge changed, Fuel line routing is currently being planned.

Gotta come up with a good, repeatable way to drill the bungs. Might have to make something to let me slide it back an forth under the benchtop drill press.

[DanStokes]

I think a drill press jig (or is that a fixture) would be the way to go. Unless you have a Bridgeport (maybe in my next life......)

pity the Mopar fixture won't work here.
