Ok, as I am preparing to buy a ton of stuff for may 2.0L SPI which now resides on an engine stand, can one help me/explain what I would need to do in order to turbo my 2.0L SOHC SPI engine, in the sence as what to do about fuel? (Since I have no fuel return line?) Any and all help would be very helpfull!?! Thank you for your time!

2.0 SPIs don't have fuel return lines? That's odd.
Only 97's do. Ford went to return-less fuel systems on a lot of there cars.

What mod's do you plan on doing to your 2.0?

If turbo, I'd suggest MIC: MAF/Injecotrs/Chip.

you can also use haltech on the SPI. crank0r from erdt did it and it worked well. nice thing was when he swapped his gtR in all he had to do was some wire and remapping.

But crank0r had a return line.

Ok guys, I have decided that since I would want to do this the right way, I have decideded that perhaps I should first begin with a "Beginners" turbo setup which I can add to later, my goal being 6psi, for my little 98' 4-door, before I do it to my 99' 4-door. and with that said I have a couple of specific questions I'd like to ask you guys:

1.) With out having a fuel return line, am I able to still use a FMU?

2.) Would a FMU, and a 5th injector setup perhaps be enough for 3-6psi of boost?

3.) With out ripping the car apart, since I really do not want to rip the 98 apart like I have the 99, would it be possible to use a fuel return line and then a FMU to allow of turbo'ing?



After thinking about it, realistcally I would rather start with a small basic turbo setup, as to "get my teeth cut", than to dive right into a $40,000 setup if ya' know what I mean...

1) No, you can not use a FMU.
2) A 5th injector control will work (as long as the electronic fuel pressure sensor does'nt mind a pressure drop)
3)possible? yeah, practical? no. There's a lot more to the 98+ fuel system then just a different rail.

Ok so, for the time being what should I use which would be the easiest/safest for me to do, this being my first "Turbo Setup" which I have ever attempted (Yeah, I have built more than one 400hp 350SB, but go figure turboing my car eludes me...).

So the jist of what I am getting from you guys is that the FMU is out of the qustion, for my "Experimental 98 4-door", so I should perhaps go with the Maf, Injectors, and chip? Could I do that with out having to redo the fuel system?

Or perhaps could I use injectors, a MAF, and a Megajolt Lite Jr in order to acomplish my goals of a low 3-5psi boost for my first project?

In other words if anyone minds just saying it, what the hell would ja' use for a basic 2.0L SPI 98+ fuel management system for a turbo which would be pushing 3-5psi boost?

A MIC is just that, larger MAF, Injectors and a custom chip. There's no "redoing" anything.

With a MIC you dont have to worry about fuel pressure limits or ignition timing, the only limmit is how much power you can make. You also dont have to worry about rewiring anything like you would with a standalone, and a Chip is cheaper.

so all I do is call up say Diablo motorsports and say "Yeah, I have a 1999 Ford Escort with out a fuel return line, and ummm..... yeah, I wanna make 100 billion HP (being sarcastic) using a maf from a 5.0L and #24(?) or #48(?) high impendence injectors? Can I also get a side order of BBQ wings with that too?"



Ok, in all seriousness, what should be known about my car when I call em up, as in what would be needed to be known in order for them to program my chip correctly?
I live in the middle of Wisconsin, and I know of only one local place that has a dyno, and I think they specialize only in trucks.... so that kind of rules out bringing it in and have em tune it correctly....


I get the entire gist of how "MIC'ing" a car works, I'm just at a loss on how you would get fuel map/ignition maps correct since I'm in a position that would mean bringing my car somewhere to have it tuned, in a place where the odds of finding some one who would do that are slim....

Ha thats what I'm doin. Well I have been in touch thru email with a guy that owns a shop about 50 miles from me and as soon as I get all my turbo stuff into my car(on the engine not in the back seat)Im gonna drag it up there and have it tuned on the dyno. HA AHH AH I CANT WAIT!!!

O yea, the chip is costin me 350 and dyno for a day or however long it takes is 125.

Your going to want to get the biggest high impedience injectors you can get and a custom MAF from like Pro-M as well as that chip. I think the limit is like 50lb injectors for high imp.

That or you could get a custom fuel rail made (not a horrible idea anyways), run a return line, and use a pump for an Escort with a return style system. Basically just steal all the stuff from a 97. Then you could do standalone.
