Hi Guys,

I'm nearing the completion of my mod list for one of my FCs (89 T-II), and wanted to get a few opinions on the fuel enrichment I've been contemplating.

I thought up of two kinds of fuel enrichment ideas:

1st Idea:

- FD Fuel Pump
- Stock (4) 550cc injectors
- Haltech (or Greddy Rebic III) Additional Injector Controller w/ (2) 720cc Injectors
- FCD (Custom Paul Stoaks)

2nd Idea:

- Apexi Super AFC
- G Force Engineering EPROM
- FD Fuel Pump
- (2) 720cc in Secondaries

I kind of favor the 1st idea since it would seem to be the most efficient (as far as MPG goes). The additional injectors would only come online when needed. The second idea removes the FCD which is good, but with the AFC controlling the injector pulsewidths, the car would be running a lot more richer than normal. I would like to go Haltech, but wanted to keep costs down (I have most of the stuff), and not to mention keep things closer to being legal.

Here's a list of mods that it would have to support.

Engine:

- Trust / Greddy Airnix Filter
- Custom 3" ID Turbo Inlet
- 3" ID Turbo-Back Racing Beat Exhaust
- Apexi Blow Off Valve
- Apexi Boost Controller
- Custom Garrett T04B (Compressor) Hybrid w/ Hitachi Centre housing and exhaust housing, ported wastegate, and clipped turbine (I don't have the A/R handy)
- TB Mod (Removed Secondary Throttle Plates)
- Mild Street Port
- MSD 6A Ignition Pack (leading only)
- Greddy FMIC

With these mods, I'm hoping to acheive a reliable 300 - 320 rwhp.

Any thoughts comments of suggestions?

You have the same mods as me. For the exception of the mild street port. Our turbos are the same (modified hitachi, ball bearings, T04 front, stock back).

For fuel I just added 720's in the secondaries and they work perfect with my APEXi SAFC.

Once I get a bigger turbo then I will use my additional injector ports on my greddy elbow. I have the injectors inside just waiting patiently.

 

I dynoed 240 to the wheels with a blown apex seal about a month ago, ( I have a new engine now) and at the track I ran 13.5 at 106 mph.

I can sure tell the difference with this new motor. A lot more bottom end for sure. (dynoed 292 rwhp).

I tried the additional injector trick first.......4 550's stock, and in the elbow 2 more 550's and I was running way to rich. Total of 6 550's.
