I got this car off a friend about 8 months ago. More than half that time I’ve spent working on it. The primary purpose of the car is to keep it a working project weekend burnout toy.

I wanted to make a build thread to hear what you mustang pros think about what i should do.

Here’s some pictures of the car when I got it.

The car was originally an automatic. When I got it, it had a T5 swap. The transmission he put into had a bad syncro. It also had a bad TPS when I got it.

He had put a set of GT40P heads on it and gave me a gt40 lower and upper intake with a throttle body.

In the last few months I rebuilt the t5. Unfortunately I didn’t take many pictures. I used a ford performance rebuild and a steel bearing retainer.

How's your friend that you got the car OFF of? Out of the hospital yet? :D Sorry, couldn't resist. Cool project. Look forward to seeing what all you do with it.

I recommend an adjustable FP regulator and a wideband O2 kit.

Is this car MAF equipped?

Thanks for the warm welcome.

@John Dirks Jr , This is a MAF car. And I agree with you. I’ve never seen the wide band before but after some research I definitely want to get one next. In the future I would like to get into some programming/tuning and the wideband seems like step one.

As you said I will need a fuel regulator and probably a fuel pump.

My suggestion is don't do the underdrive pullies if it is a street car. I also would not delete the ac.

@Mstng93SSP it’s not a daily driver but definitely a street car. A/C would be nice and I still have it all sitting aside. It wasn’t working when I got the car and had no charge in it. For this season it seemed more trouble than it’s worth.

Aside from that, why not the underdrive?

They are notorious for causing charging issues and overheating. The gain you get with them is so minimal that the tradeoff isn't worth it. I speak from personal experience.

Last night I got all my fuel injectors cleaned up with new orings and caps. Then spent the rest of the night sanding the engine bay.

I’ve read the caps bust when you try snapping them on so people boil them to soften. I just hit the orings and caps with a heat gun for 30 seconds and they went right on with no problem.

I also got my dip stick to fit in this week. With my cheap jegs headers ( $100 ) they ran a pipe right were the dip tube goes.

I heated the pipe up and gave it a few taps. While it’s not good for flow, I needed to know my oil level.

Here’s a few pictures

There was a 'header bashing' segment on the motortrend channel a few years back. david freidburger bashed the crap out of a set of headers on a sbc with almost no hp loss! Unbelievable except the dyno don't lie. So no worries on that little parking lot ding you did.

Well that’s good information to know. I was trying to make it as small as possible.

I’m definitely looking into getting a wideband o2 set up for when I put the car back together. Anyone have a suggestion on brand? They’re all around $200.

I’m reading some places I don’t need an adjustable fuel pressure regulator. I’m reading lots of bad reviews on them too.

I’m thinking to get the car back running with the stock regulator and put the wideband in.

Then see what it says.
