I'm planning on starting my escort GT turbo project this summer and I need a little advice. I'm doing this the RIGHT way, so I'm starting with the fuel system. I'm starting with parts that I can convert to other cars, so if the project goes to crap, I can at least move the parts to my next car.

Anyway, I'm planning on doing a completely independent fuel management system. I am thinking of going with haltech, but I'm open to other opinions too. I just wanted to know if anybody rigged one of these up and if they ran into any weird problems.

Also, I'm going to need a list of other fuel system upgrades. Let me know if I'm missing anything:
1. Fuel pressure regulator
2. Fuel pump
3. Injectors
4. New fuel lines

1. Dont buy any fuel pressure regs from Mustang Wharehouse..they dont work...to this day I haven't been able to make a regulator work right.
---but the best quality one I've owned is my Aeromotive bypass regulator.

2. Injectors out of an RX7 work great OR my 330cc GTX injectors are for sale on eBay http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2459930547

3. Simple Digital Systems makes a good stand alone and its better priced then Haltech, but Haltech is almost a standard as far as quality.

For someone with your skills, Siragan, I would also look into the megasquirt.. the DIY fuel computer.

Haltechs are VERY expensive. They're good, but you really need time on an engine dyno to make all the extra wiring, programming and cash worth it. That money would be better spent on insurance and a down payment for a nicer car, IMHO.

An SDS system will only cost you a fraction of the dollars the Haltech would and includes distributorless ignition.

Okay... do I need an independent ignition system too, or just an independent fuel system?
Also, do I need a new MAP sensor? Where can I get one?
Also, do I need a fuel pressure riser?

Are the 330CC high enough flow? I'm planning on pulling apart the head, throwing in new rods and putting in lower compression pistons so I could run fairly high boost numbers.

The trouble is that I'll need to find the pistons and rods somewhere... anybody know anyone who makes them? I have a feeling that that will be the hardest part to find.

Since you're going turbo, the ability to program in a custom timing map with EDIS (vs being subject to the stock distributor's curve) would mean much better tuning. With boost, ignition timing is as important as fuel timing.

Low compression pistons + turbo in a BP leads me to believe you're shooting for over 250hp?

I'd guess that my goal power is going to be right around 240-260hp. I don't want to destroy my transmission. However, I also plan on gutting out some weight too.

Also, I'd like to have this be an efficient modification... I want the cam timing to be right so I don't get any flow reversal and I also want a good intercooler. When it comes down to it, I want to produce the most horsepower per pound of boost to reduce the strain on the engine. Anybody can run 22psi into a BP and rip butt, but my goal is to not rely on boost alone and to do it with the help of good tuning. to keep my boost numbers fairly low.

alright... where would one buy these bearings and rod bolts? Also, a custom set of pistons sounds like a lawt of munnie....
www.summitracing.com - give them a call - they can get the bearings and bolts.

www.jepistons.com - give them a call - they can get a quote for 4 8/8.5-1 comp. pistons for you. Know your engine specs and what you plan to bore out too before you call.

I personally will probably go with the Haltech eventually. I have an account with Haltech. So I can get them and beat alot of prices out there.

I'll look into picking up accounts with anyone you are interested in getting stuff from. I'd also love to make a custom manifold and downpipe. Jet-Hot is like a block away so We could really get you a sweet setup.

Awesome. Thanks for all the help guys...

For this summer, I'm planning on only doing the fuel management system. I'm purposely doing this because I want to have quality parts all around my build. So many of the "kids" on this forum are all like "turbo turbo turbo!!!" and then they wind up buying a garett T3 turbocharger online and they don't have any of the other parts. In the rare case that they actually do put the turbo on, the performance they get sucks. I look at it from the standpoint that even if I don't get the turbocharger on, I at least have a sweet fuel system to boot.
The only real limitation I have is cost, but if I give it two summers rather than one, I think the extra wait will be well worth it in the better parts I will get.

I think I will end up going with haltech. The reason being because their fuel management systems will work in pretty much any car out there, so even down the road, I can pull it out and use it on another car in the future. I think it will be a worthwhile investment. The real pain in the ass with haltech is that they get you on the sensor equipment and wiring harness. I really just need some pigtails to hook everything up, and calibration is going to be a bitch. Either way, I'm a mechanical engineer in training, so I should be able to figure that stuff out.

Concerning injectors:
Should I go with 550cc RX-7 fuel injectors? Are these from a 1st, 2nd, or 3rd gen? Turbo/non-turbo? Will they fit the stock 1.8L BP fuel rail? Do they fit the harness?

Concerning the fuel pressure regulator:
I've never installed one. Do I need a new fuel rail?

Fuel pressure riser:
Do I even need one?

Fuel lines:
Do they need to be replaced?

Fuel pump:
Should I go with the walbro 225L/h pump? Where did you get yours, blade?

most injectors are universal fit. the things you need to look for are high or low impedance. stick with rx-7 injectors and fitment will be just fine. if you get nissan injectors they are a different plug. so avoid them! depending on your maxium boost you want the injector size will vary. the gtx injectors or only good the amount of boost the turbo will make with out over spooling which is 15psi. 550cc injectors will let you boost to 25psi and can be tuned down with your haltech to run correctally at 8psi if you want.

fuel pressure regulator is a good idea. do to the fact its one more thing you can adjust. its not a thing that is needed tho just nice to have.

fuel pressure riser is unneeded the walbro 255lph will do it for you.

stock fuel lines are good to over 300hp that i have seen. possibly more then that but not many escorts are over 200. its just a waste to re-do them for a turbo set-up that is going to be a driven regularly.

Walbro 255lph can be found on ebay daily. 89-93 rx-7 is a swap.

hope that helps.

i'm no "cc" guy, persay, but you'll want whatever amount of cc equates out to 35-42 lb/hr (for us domestic guys).

Haltech's an awesome system, but harder to tune than an SDS (from my personal experience). I'd reccomend finding a friend or two who have messed with them before..

Like neuspeed said, no fuel pressure riser needed, just get the 255lph pump. the fp regulator should mount where your stock one does.

The only thing i don't like about neuspeed's post is he's talking in psi and not HP. Your crank hp is what will decide how much fuel you need to run... not boost. That's depends on the turbo and what other mods you have. Two engines running 8lbs of boost can be ENTIRELY different engines, as i'm sure you know.

like he said, no new fuel rail. :) he's pretty much got you covered. ford 35lb/hr injectors are a dime a dozen and should be fine up to about 300hp. i'm honestly not sure if they're the same as their "mazda" counterparts though. if they are, i have about 2 dozen of 'em layin' around if you want a few.

Neuman, injectors aren't always quite universal...those 330's on ebay right now, I originally sold them to a friend with a Mazdaspeed Protege but Superior Racing Development down in Phx couldnt seem to get them installed.

I personally think they screwed up somehow and didnt know what their doing, but according to them 2.0L Mazda's use a different injector.. (I'm with you on your current thought of B.S. though)


Anyhow the injectors to get:

Mine on ebay! are perfect for your upgrade...from the GTX

or Mazda 460cc injectors.

awesome. thanks a lot again guys...

Concerning the fuel mazda 460cc injectors... um. Are all the 460cc injectors that mazda made the same injector?

Concerning the fuel pump, do I need any special gaskets or anything?


I'm planning on pulling the block apart and rebuilding with stronger stuff. Even though I'd like to keep the boost numbers low, I'd like to have the flexibility of messing with the boost controller and running an insane 24psi if I felt saucy... :D
But for all intensive purposes, I'd like to keep it under 17psi.


Concerning management:
should I get the full ignition and fuel management system from haltech, or only the fuel management?
