Ok I am going to level with you all. I always wanted to turbo a car, and the opportunity popped up earlier this week. One of the fellow 02ers posted a system in parts for sale. It is a complete system from what I understand. It was advertised with a megasquirt and boost controller that I passed on, as I have my heart set on a Haltech EFI system.
The challenge is always time. I couldn't take the car off the road for the 3-5 months to have the system fabricated for my car, so a tur
First of all, thanks to all of those who have supported me through this project. It has been fun and challenging, but not being able to leave well enough alone, I have embarked on incorporating the timing function of the Sniper EFI into my build. What am I hoping to achieve by this... no clue.. if I were forced to give a reason... I guess I would say because it was there, and life is too short to ponder things that satisfy your curiosity.
So after consulting a lot of people, an
So... it has been quite a journey. At more than one point I felt that I wouldn't be writing this for the following reasons.
1) 40MM DGAV carbs are significant for these cars. There are many stories of a 38MM not running as good as a 32/36, let along a 40mm.
2) Could the injectors run efficiently down to the flow rates of a 2L? ( we can talk about this one a little later).
3) Would an adapter work for the stock intake? Would it act funny? Would the added height make a
Ok so I am having a problem. I can set up the car just fine, part throttle, full throttle, cruise is just fine. When I come off the throttle, the revs will drop, and either catch at about 800 rpm stumbles or almost stalls to 100 RPM then recovers.
When I take my foot off the gas, it pins full lean, even if I force the system to still pump fuel. So it is one of two things
1) My spark control is bad or something with the ignition that I can't figure out. Everything has
So I ran some errands this morning. I decided to put on the data logger and here is what I got. You can download the sniper EFI tool (windows only) at the following link. The timing should be accurate to within a degree or so. I am running a 123 so I can change the advance and vac curves. This is all I know, I need to learn from here.
So it is in and works. But I can't tell how well it works because the Linx cable linkage that I modified sucks. The gas pedal is more like an on-off switch, very sticky. I haven't drifted the car so much in my life. Genuinely entertaining, but quite harry at the same time, especially in downtown traffic.
So I am in the midst of getting some bits made so I can use my sweet sweet heim joints. I am copying what Australian Vespa Guy did with an L bracket thing mounted to the brak
Ok, so I put in an MSD 6A a while ago, I was in a bit of hurry with the intent of coming back later and tidying it up after I knew that it would work. So now is the time I fixed it up. Here is what I pulled out of it. I know I am not the only one to have done something to come back and fix up later... but still what a pile of shit job I did. Everything is now soldered, shrink wrapped, taped and zip tied.
I am off to finish the wiring today, purge the fuel lines to get the residue
The fuel pump is in and wired, 02 sensor is installed. Coolant system buttoned up.
Return line completed. I have a -6 header fitting, but no space on the fuel pickup to put it, so I plumbed in the return to the breather pipe that the California cars have in the tank. Not a permanent solution (I promise). I am taking it first thing to my fabricator to install the 02 bung properly, and I will have him put in the -6 header when I am at it. And have him check everything over to ma
Ok so in light of the fact that fuel pressure is very, very important to fuel injection operating correctly. I decided to get a digital fuel pressure gauge for the car. With old gas tanks, and aftermarket parts and fuel system, you really don't know how the car is going to react. Rather than guessing what it is, or if something is going wrong, I can take fuel pressure out of the pool of questions. I also wanted to see the change in fuel pressure under different driving conditions. Worst
So I got my intake back... in one day. I think he is getting a little excited to see this thing going. Some more picks. I thought that there may be an interference problem with the coolant pipe that comes out by the carb, but it is on an angle and will not interfere with the TPS sensor on the EFI.
I realized after the mock-up that the fuel inlets will have to be around the front since the throttle lever needs to hang over the side to work. This is something I needed to commit
So I quickly realized that the adapter for the Holley to Weber is for an approximately 36MM bore, the Sniper is 40mm bore, no biggie, I have to get the intake off and hogged out, so I will get my guy to make it bigger at the same time. I am pulling off the intake tonight (hopefully) to get my guy to work on it tomorrow.
The height seems ok, the EFI with the adapter is about 10CM to the air cleaner mounting surface, I measured the Weber to be a bit over 11CM, If I were to include t
In an attempt to expedite the changeover to the Sniper, I want to pre-drill a fitting. Can anybody add to what is mentioned in the forums?. I am thinking in the housing going into the head...... Is everybody ok with that? or do we have hose people as well?
I would love to know.
I am a big data entrepreneur in real life, so this has got me thinking about the data coming from the engine and how its interpretation results in the adjustment to the air valve and the injectors.
I have read the manual. The first time I was was completely sober, along with the second and third time... the fourth time... not so much. It seemed to sink in the fourth time around a lot more. The way that this system allegedly manufactures the digital version of real-life parts of a
So I finally stopped navel gazing and ordered the gear up to install a Holley Sniper 2BBL EFI system. The parts list is below.

SNE-550-849 2 BBL EFI THROTTLE BODY $849.95
SUM-230615 S.S. HOSE -6 15FT $57.99
SUM-251000 FUEL PUMP EXTERNAL $119.99 (ordered this as the Holley unit seems to fail quickly in some cases)
SUM-251010 FUEL PUMP MOUNTING KIT 1 $7.99
VPE-16612 -6AN TO 10MM X 1.0 METRIC STR $11.90
