Tuff to answer your question, NO! so sorry so late (ya have to say that with a oriental accent)

I'd like to point out however that without someone with different understanding jumping in, then further discussions that we all benefit from to improve our own understandings would not happen.

Sure it may sound like someone is nitpicking or trying to prove thier point, but that's because they have a different view. In the end, everyone see's the information and can then make an educated decision based on the discussion.

/end soapbox

btw, this really is an awesome thread. I've thought about turbo in the past long enough to realize I didnt have a clue and wouldnt consider even attempting it. With this thead, i'd at least entertain the idea now of doing it sometime in the future. Great info!!

Yea Turbo is black magic, if it was not for Scott I would be banging around with my 1775, but man I want to get my front end off the ground!

This has been a helpful thread, keep the questions going guys, don't consider anything stupid or dumb.

you need to put your front end on a diet.

Scott, what are your feelings on this? Could you make up something similiar?

I have been eyeing it for a couple years. I really want to go with FI. I am tired of pluging idle jets and having the car blubber its way over big rocks and steep hills.
Baja5's car has the CB FI and on a cold morning in the desert, it took me several minutes to get my car warmed up to where i could let it idle. He turned the key and walked away. The FI system alone goes for about $1800, so the turbo setup would only cost an additional 1400 to have the best of both worlds.

That is a pretty good kit. I have made quite a number of FI turbo kits...They all run in the same ballpark price of what the CB kit costs. Most of the time I personally will take a slightly different approach than CB does. I have no problem with what they do...other than the kit is set up like two 48mm carbs. So you do have to get them synchronized just like carbs. I use a center mounted throttle body like the one found on a FI 5.0 ford or a suby.

For a system like that with the bigger injectors and T04 on a 2110, what size fuel/return lines are necessary?
I ask because I'll be cutting into the pan head soon, and that would be the time to run a larer aluminum fuel line(s).

To add to Dave's question. Where should the return line be in the tank? If it is in the top seems it would make air bubbles that would not be wanted. On FI in tank pumps the return exit is at the bottom of the pickup of the pump.

5/16 is more than enough and I run the return into the bottom of the tank.

Many guys will put a T fitting on their existing tank outlet, so the return is going to the same spot as the feed. But it has to be made large enough to handle it. It's kind of a weird set-up if you stop and think about it. But it does work

What were their problems?
I should throw in that I personally don't run a line back to the fuel tank, I use a surge tank on all my Fuel injected stuff and just run the return line back to it.
It's just that I run with a bunch of guys returning it to the tank with a T and none of them are having any trouble. I have always said that they "should" be having trouble...but...when they spend the whole day driving around next to me...I guess that "should" kind of flies out the window.

Does the surge need to be vented to offset the return pressure, or is it simply offset by backing up the main feed into the tank?

Are electrical FI pumps positive displacement? Or is the return more for the residual pressure than volume?

Finally, if turbo is a great item for the sand, is it beneficial for a desert based car?

scott the viking · Post by **scott the viking** » Wed Mar 14, 2007 10:25 am

Yeah...I could see a need for the use of a low pressure pump if you have a surge tank that looks nice. Because you would mount it where it could be seen (in the engine compartment). On a rail or bug, there is almost always room under the fuel tank for a small surge tank, so it's just gravity fed and hidden from view. Most of the time I just make one out of 2 1/2 inch stainless tubing and weld end caps on it. I considered going to FI many times on my Bronco...but it was a Stroppe, So I left it alone as much as I could.

The extra pressure just goes back to the tank.

The return is for the pressure, for cooling of the fuel and for extending the life of the pump. Nearly all FI pumps are positive displacement.

Turbo in the desert? While the power would be much better and even usable in the desert terrain....I would say that it is more of a personal choice kind of an item. IE...a turbo does add more moving parts to your vehicle and does build a little more heat. I personally would run one and keep the boost on the low side of things. Lots of turbo charged cars in the Dakar rally (and that's saying something). I can tell you this....I would NOT go the cheap route when installing a turbo on a desert car...I would have one custom built with all the right goodies.

That 3.2 is already near your 091's limits, there DG. The only reason I was thinking about it was sand is supposed to be easier on a car in compairison to desert. You could try this gem, should bolt right up.
