JWT Cobra MAF Clarification

July 26th, 2008

I had some concerns about differing part numbers for the 1993 Mustang SVT Cobra MAF that could be used with a JWT programmed ECU. Because of the age of the car, it was becoming difficult to find a new MAF. In addition, I found differing part numbers from what JWT listed.

Below is an e-mail from JWT stating what is needed:

The OEM stock 1993 Ford Cobra MAF sensor is the only MAF that we
program for and not any aftermarket MAF sensors that exist (ie:
Granatelli, etc.). There are two different part numbers associated
with this MAF sensor and the part numbers must be an exact match for
the MAF to be the correct one. Here are the part numbers for your
reference.

Ford Dealer parts number = F1SZ-12B579-A

Ford Engineering number on side of MAF itself = F1SF-12B579-AA and
also on MAF = AFH70-02

That cleared up the confusion I had, since many of the remanufactured MAFs had the F1SF-12B579-AA part number listed. Hopefully this will do the same for anyone who has similar concerns.

Fuel Upgrades Continue

July 25th, 2008

The replacement top for the fuel pump canister came in today, so I finished up the Walbro fuel pump install. If I didn’t already know the Walbro pumps were so loud, I would have thought the pump was bad!

After getting a tip that the Custom Steel fuel rail did not have he proper seats for the MSD injectors I would be running, I decided to order a JWT Fuel rail. The CS fuel rail is a nice piece, and I know of a few people that are running them with MSD injectors, but this was just a personal call on my part. I also ordered an Aeromotive Fuel pressure regulator and the proper fittings to hook it up to the JWT fuel rail. The rail and FPR should be in some time next week.

Long Overdue Update

July 20th, 2008

After a while of not posting any sort of update, I figured it was time.

The end of June was spent getting my ducks in a row to make sure I was all set for emissions and inspection.I only put about 1,800 miles on the car since last June, so I was exempt from emissions.

In the mean time, I have been accumulating some more parts. I bought and installed the parts for the in-line fuel pressure gauge. B&B performance was the only company that I found that made a one-piece (this is key) adapter with 5/16″ barbs on the ends. The B&B adapter has a 1/8″ NPT port in the center that allows you to screw in a fuel pressure gauge (I ended up using a summit liquid filled gauge).

To get the B&B adapter, I went to our local speed shop (K&G). I often overlook local speed shops, since the local import shop has left a bad taste in my mouth. K&G mostly services muscle car guys, but there are a few local import guys around this area that go to them as well. Lynn is very helpful, and always willing to go that extra mile.

I was going to order the MSD 50# injectors from Summit, but Summit could not get them until August! I went to Lynn and he said he could have them within a week! Unfortunately, the guy at MSD shipped the 72# injectors (despite the fact that Lynn told him what I wanted and gave him the right number). It’s no big deal though, and Lynn got right on the phone to straighten it all out.

I’m working on getting the Walbro fuel pump installed. Since I broke one of the plastic nipples on the canister, I need to wait for a replacement from Nissan. Other miscellaneous parts I have include: all turbo fittings (water and oil), Cobra MAF, turbo manifold studs, and injector clips and o-rings.

Right now, I’m trying to source another stock B15 SE fuel rail. Once I get that, I am going to take the intake manifold, throttle body, and fuel rail in to get powder coated in crinkle flat black. My hope is to get the intercooler piping and valve cover coated in the same finish to tie the whole engine bay together. This is not a show car my any means, I but I want it to have a clean look.

Next up on my parts list will probably be the purchase of the Synapse engineering blowoff valve and wastegate. I’m more concerned about the wastegate, since I want to drop off the manifold to have it modified for the external gate.

I really need to get some pictures up! Maybe next time.
