Hey all, I am going to put a turbo in my Mustang in the coming months and have no idea on what my tuning options are. What i have gathered: dyno tune with custom chip. Need to get a new chip if you mess with you motor and is pretty spendy. megasquirt. can diy but pretty difficult to use...

I installed an explorer TB and kept my stock tps sensor. I hear the voltage should be around 0.9 but which wires do I use to test this? also, i noticed the stock egr plate between the TB and intake is smaller than the TB, do people port this piece?

I'm looking for a new maf and looking at the pro-m specifically. Here on jegs Pro-M Racing 1989-95 Ford Mustang Mass Air Meters - JEGS they have two plastic 24#ers for the 89-93, one says cold air tuning, what's the difference?

I'm putting my car back together after a hci swap and have this bundle of about 4 vac lines I forgot to mark when I unplugged them. You can see them bundled together in the bottom/middle of this pic. I remember the long black one goes to the smog pump but that is it. I have a vac diagram but i'm...

Are the explorer pushrods the same length as the Mustang ones? 91 Mustang I am wondering about by the way. Just want to know if I should have grabbed the explorer pushrods along with the heads.

I am installing the explorer intake on my 91 gt (intake is one with internal egr) and there is no line for egr coolant. I heard I can tap the rear for coolant but I would rather not. what are my other options if i keep my egr?

I could not find the answer to this damn question so here goes. The large plate that bolts into the valley which pushes down on all the lifter guides, how is this installed? It doesn't look like this piece bottoms out on the engine but i want to make sure. I am in the middle of an hci swap and...

i'm thinking about getting a new maf and would like to get a 24# calibrated one. Thing is I don't want to upgrade my injectors quite yet. So if i get a c&l 76mm maf, can i use my stock maf tube inside the c&l?

Are the stock rockers from a 91 stang and the rockers from gt40 heads basically the same, performance wise? Trying to decide which to use.

I'm slapping on a pair of unmilled gt40p's and i'm hoping the stock pushrods will work. I was going to order some shims just in case but i could only find them in .030 or .060 thickness. These seem like they may be a little too big so would I have to order new pushrods if my geometry is off by...

I talked to some guy who is selling 5.0 shorties and he says they are Ford Motorsport steel headers. When I look online all i can find is stainless or ceramic shorty headers by ford, and he claims they are not stainless. So does ford make regular steel shorties? I'm thinking that maybe they are...

I have some high mile 40p's and plan to get them worked. If i resurface the bottom of the head, do I need to compensate by shaving some off the lower intake to make sure everything lines up? Also, when i put the p's on my stock shortblock, should I be using the gt40 rockers? Can't wait to...

I'm replacing the struts on my 91. When I try t tighten the rod, the piston just spins. How do I get this thing tight?

I got stock 91 GT rims and am looking for a good summer tire. Looking to spend $100 per tire. Want something in 225/50. I have looked into the Cooper Zeon 2xs, BFG G-Force sports, and Dunlop DZ101 (reviews seem poor though). I got a mostly stock GT so I don't need something that will stick a...

Anyone got a link to a good guide that will assure I don't kill myself while replacing the front springs on my 91GT?

I am going to order some Vogtland lowering springs but I still will have my stock shocks and struts. My car will be lowered anywhere from 1 to 1.5 inches. Do I need to get shocks and struts that are different than the stock equipment? What I really need is someone to recommend a set of...

I was going to get some new rims but I can't justify the price anymore. I got a 91 with the stock ponies and am just going to get tires for these. I got 245/45s now and they hang over the bead and I don't like the look. I want to get a little taller profile too. What are some size I should...

I want to order some Cobra Rs and found some for $600 shipped that I might buy. There are two 17"x8" and two 17"x9". I hear 275s are good for the rear but not sure what to do up front with the 8" wheels. I would kinda like to have the profile be the same in front and back. So what size tires...

Here's what I got. A 91 GT with smaller tires and about a 3 inch gap between the fender and tire up top. I was considering the pro kit but it says it only lowers about 1.2" in the front and 1 in the rear. I found this cheap kit on ebay which lowers it almost 2" front and rear. Anyone used these...

Will a T-5 from a 94 Cobra fit in a 91 GT? If not what will I have to do to get it in there?
