1998 Cobra, BAB, Build Thread
- Thread starter 06LLGT
- Start date
Well, I finally picked up my car today. The swap went pretty well. I don't have the pictures yet but I will get them so, just need to remind Tim to email them to me.
A couple issues came up but were easily overcame.
The AJE Racing 94-98 Crossmember would not line up due to 98's crossmember mounting point being in a different location from 94-97 cars. So Tim had to unbolt the mounts and move them up about 2'', drill new holes and bolt them back in. Once he did that the AJE Racing crossmember went right in.
I had to have the motor mounts replaced due to one being torn apart and the mounting bolt rubbing on part of the motor mount cause vibration and lots of noise. The header was also rubbing on the motor mount and chassis.
Tim forgot that when running a 2003-2004 T56 in a 94-98 car, you will also need a extended range speedcal, so I just ordered that about half an hour ago from Dallas Mustang.
Lastly, I will need to order a Steeda Quadrant adjuster, the one I have now only has a bottom and top hook so the clutch release is almost at the bottom of pedal travel. If it was hooked to the top, it would release way to high.

I've been meaning to post my dyno sheets up but I've been forgetting to upload them.
Had the car tuned back in February at MaxV. Now, keep in mind, the motor is built for boost; 8:1 compression, P&P'd B heads, stock cams, forged rotating assembly, etc. Other mods can be veiwed in first post. So these are pretty decent numbers for a FI motor that's running NA at the moment. The car likes a little more fuel being that it's built for boost. Average AFR was 11.9. Tuned by Jon Lund.
Max HP; 257@6156RPM's, WCF 269@6156RPM's
Max TQ; 239@5137RPM's, WCF 250@5137RPM's
AFR; Min 11.2, Avg 11.9
It was also making power past 6,156RPM's as you can see on the sheet but Tracy didn't take it past that.

A couple updates/progress;
I got the Dallas Mustang Extended Range speedcal installed this past monday, I'll have to get pictures sometime soon. Only issue that I have now is that my cruise control does not work past 45MPH.
I got my new quick release clutch quadrant in, just needs to be installed, so I'll probably take it to MaxV since I don't have a lift and a helping hand to install it.
My car seems to hesitate on inclines when I go to take off, feels like it's not getting fuel and wants to stall so I have to take it up to 1,400RPM's so it won't stall when I go to take off on a incline.

Another update:
Got paid today, so I took the car by MaxV to have the new 50Resto quick release clutch quadrant installed. Turns out, we forgot to put a T56 clutch cable on when Tim did the swap so they installed that also. Clutch engagement is now at the perfect spot in the pedal travel. Now the TOB isn't being touched by the clutch fork when it's not supposed to and it's not spinning all the time anymore lol, so it's quieter.
I also had a high idle issue that isn't tune related. It would idle at 1,200RPM's whiled stopped and in neutral coming to a stop sometimes and there was nothing that would bring the RPM's down So I cleaned to the throttle body per Tracy's advice. Once I cleaned the TB I turned the car on and it now idles at 1,400RPM's, and once again, they won't come down.
I than disconnected the connector to the TPS and the RPM's dropped to 1,000RPM's. So I'm thinking that the TPS is bad because one, it's the original TPS, and second, just like the IAC, the TPS can go bad after awhile due to the heat. I'm waiting on Tim to call to talk to him and see what he thinks.
