To Carb or not to Carb? Fuel conversion. Reply #15 – April 13, 2009, 10:13:46 AM Quote from: danzajax;267130Its not a driver. And how would swapping out my pump for a higher flow fix lumpy cam + Speed density pyness?I could care less about whether you're running SD or not. If you're upgrading the power output of the engine, you will need more fuel pump. You mentioned deleting the in-tank and splicing in some in-line pump, and that's just not needed. That is what I was refering to, not your choice of metering/injection.And yes, I'm busting your balls about converting to carb.The discussed MS conversion is a good one. Granted there is a learning curve when it comes to tuning, but in the end you get a better idea about how it all works in the end.If you want a nostalgia "look", get a 4bbl TBI unit (I've seen them) and use that instead of a "std" port injected set-up.

That is what I was refering to, not your choice of metering/injection.That was if I installed a low pressure inline pump. I would need something to suck gas from the bottom of the tank because the in-tank unit would be gone.Quote from: Chuck W;267198And yes, I'm busting your balls about converting to carb.Tell me about it. I get more love from the 16 year olds over at VWVortex when I work on my 84 rabbit. (Which is mechanical fuel injection I might add) Where's all the brotherly Coug-love?Quote from: Chuck W;267198The discussed MS conversion is a good one. Granted there is a learning curve when it comes to tuning, but in the end you get a better idea about how it all works in the end.Agreed. But, I still don't buy the argument that the system is "already there". So far, I identified that I would have to switch out the Upper/lower intake, add a MAF, Swap the computer, fuel pump, injectors, splice/repin the computer. Sounds to me like the only thing left over from the "already there" system is the fuel lines/rails.Quote from: Chuck W;267198If you want a nostalgia "look", get a 4bbl TBI unit (I've seen them) and use that instead of a "std" port injected set-up.That would incur the cost of both systems. I would need a MS, new harness, lower intake, fuel reg (b/c TBI uses a lower fuel press if I recall), pump and filter.Your 80' is carbed isn't it? Quote Selected

It was still carbed, but it sure as hell wouldn't of stayed that way. It was running carbed because it was, well...running. I wanted to drive it after finaly getting all the susp , brakes and interior done. Hated the carb though. The car was going to get an SHO engine swap if it was still in my hands. Even if I chose a different engine, it was certainly not going to be a 5.0 and definitely not carbed. The guy who has it now is going to be converting it to EFI. Quote Selected

To Carb or not to Carb? Fuel conversion. Reply #21 – April 15, 2009, 07:51:27 AM If you want to go carbed, do it. Mine was TBI when I got it. Under the hood was a horrible mess. Wires cut and hacked, ran somtimes, sometimes it didn't. So I went carbed. It was a little easier on my '83, as the fuel pump was inline under the car. I changed out the intake, used a 2 barrel, and changed the timing chain cover to accept a mechanical fuel pump. Removed the inline fuel pump, and was able to use the existing fuel lines. Later, when money was a little better, (I was 17 when I bought the car) I then upgraded to a 4 barrel, bigger cam, intake and heads. Quote Selected

I guess I should have used the SCCOA as a reference instead.Actually the question was how to convert the fuel system. Apparently I struck a nerve. I appreciate the offer to re-pin the connector. I am just surprised that people seem to get so worked up over the conversion. I was just trying to support my argument that maybe converting isin't so crazy. I appreciate your opinion, and if ya ever break down in SA drop me a line and I would be more than willing to help. Everyone has EFI, I just want something kinda different. This car is an experiment. A twin turbo LS1 would make a pretty rude cougar. Sounds like you got beef with my Rabbit too (actually its my girlfriend, i just resurected it).Just so you know, my dog loves it. (He digs the cougar too until I start it) Quote Selected

To Carb or not to Carb? Fuel conversion. Reply #26 – April 17, 2009, 02:07:45 PM Thanks V8. Its actually taken by My girlfriends sister. I will tell her so.They made Rabbit Convertibles for about 3 years I think (identified by their chrome bumpers). Then in 85 they re-named the rabbit to the golf (and gave them plastic bumpers) and the rabbit vert to the Cabriolet. VW thought the name was driving away customers. Interesting note, VW just announced the new model rabbits 07-09 will be renamed the 2010 Golf. I guess things don't change. When she bought it (for next to nothing) . The previous owner had tried to replace the head and botched the job. After some extensive re-timing and fixing vac leaks, it runs pretty well. I recently replaced most of the front suspension. It drives pretty well for 90 hp and 25 year old.-DZ Quote Selected

To Carb or not to Carb? Fuel conversion. Reply #28 – April 18, 2009, 07:16:39 AM I swapped from EFI to carb when I first put my car together (I was careful not to cut anything up to give me the option of a future re-conversion). With the upgrades to the motor it made no sense to put stock stuff on it. Money was tight so I put on an RPM intake and a Carb Shop Stage II 600 Holley. I ran it for a couple years that way. It always ran well with only two complaints: It needed an idle up selenoid when the A/C kicked on (the slowed idle set up a resonance) and gas mileage around town sucked.I did swap back to EFI. The goal was to pick up the milage around town. Saved up the cash and strarted picking up parts. It was considerably more expensive than I expected. I spent $1,000 collecting all the associated parts (including mass air). It ran like ! Idle surge, stalling. Tried all the tricks out there to try to tame it, no luck. Bought a mail oder chip ($250) no luck. Bought another MAF meter ($150), that helped a lot. Ended up getting a custom tune (add another $600). Ran great! Around town mileage didn't improve much though.For the price of stroking the motor, I got EFI.In the years since the EFI swap it has run fine. A custom cam greatly improved drivability. Around town milage finally improved.IMO either option works. My experience: Both can run great. EFI can be much more expensive if all the stock stuff needs to be upgraded.Camshaft selection can give EFI fits which may require custom tuning. Quote Selected

Still, only two people actually answered my original question. Seriously, no one wants to run a carb just for the hell of it? At least Bane isn't bustin' my balls.I'm going carb myself. But I'm an old school kinda guy. Besides, my car didn't come with a gas tank. Quote Selected
