Hey fellas, I did an H/C/I on my 93 lx with aluminum gt40 turbo swirl heads, gt40 intake, e303 cam, and i used the 93 cobra electronics (x3z ecu, 24# injectors, and the 93 cobra 70mm MAF calibrated for the 24# injectors) but my 93 was a 5 speed. It worked great and I loved the setup so now I am...

Ok fellas, I did a quick writeup of how to tune fuel pressure off the dyno on the street for best performance. My disclaimer is just dont get caught! :flag:

Ok I took my old block apart because it was reading no oil pressure at idle and i thought i spun a bearing but when i hit the gas the oil pressure would go up to almost normal. It would also knock at low rpm with the low pressure. I took the whole thing apart and saw that I had split the...

Just wondering what anyone thinks I should gap my plugs at for a dry 75 shot? I have full MSD ignition, (TFI blaster coil, billet distributor, 6AL box, 2-step limiter, and 8.5 helicore wires) Before I had nitrous I had them gapped at .060" but I was thinking maybe to go smaller because the...

I am using aluminum GT40-X heads with a stock cast iron block. What head gaskets should I use if I am spraying a dry shot approx 75 hp? :shrug:

I am building my motor back up and I want to retard the timing of my fms E-cam 8 degrees. I have been using desktop dyno and when I entered the cam specs and retarted the timing up to 8 degrees, it brought the hp and tq closer together. Now my question is can I do that? Or will I hit a valve...

does anyone know what the exact thickness is of the stock oem piston rings on the hypereutectic pistons from 93+ are? I have the piston in front of me but no way to measure it. I dont have a mic. I need the top, second and oil ring thickness, thanks.

ok so i made a thread about this problem I had a while back where my timing was showing up way off on the balancer so everyone said to get a new one. Well i did that and now it still off by the same amount so now im thinking its got to be something else. The car seems to run ok, but when I...

I have heard a few people talk of these, and well i need them. My torque boxes are cracked and torn to shreads and need to come completely out. My chassis/race shop hasnt done too many 5.0's but they have done one with the battleboxes and said it worked nicely. Anyone else had to have this...

some kid that i know that just started mechanic school is going off telling me that I need to take my brand new X303 heads apart and lap the valves so they seat right. Something about taking the retainers and springs out and putting some compound or something on the valves while they are lose...

I am just finishing up my motor and should be pushing 300+rwhp (i hope) and around 400 rwtq. With that kind of tq I am wondering if I will be able to do a hardcore launch (from the limiter at 6k) and not break the tires loose. When you do that sort of launch where you hit the limiter, do you...

I just put an E cam in with 1.7 rockers and im putting the GT40 X303 aluminum heads on with GT40 upper and lower intakes. My question is, I bought a new FMS timing chain set and it has adjustable notches for the small sprocket that goes on the crank to either advance or retard the cam in degree...

So i goto the shop to get my subframes welded on and they call me at work and tell me that they cant put them on because my torque boxes are destroyed and my frame or something is cracked all the way across and I have to goto a chassis shop to have it all welded back together and have new torque...

which vehicles model/year can I use the electric fan from and how would I go about setting it up to come on with a temp sensor rather than a switch that I would have to remember to turn on and off? :shrug:

I am looking to get some 24# injectors cheap and was wondering if anyone knew what vehicles came with stock 24# injectors that will fit a 5.0 mustang. I think the big 460 FI trucks did but not sure. :shrug:

I was changing out my rear shocks and noticed these smaller shocks that are mounted sideways, I guess to help with traction. I took them off and they are roasted so i need new ones, but when i typed in the part number on motorcraft.com, I couldnt find anything. I dont even know what they are...

I am pulling a code 44 and 94 which is thermactor malfunction and solenoid circuit failure. Im pretty sure they are tied together because they both came about at the same time so if I fix one I think they both will dissappear. So what is a thermactor, where is it and how do I fix it? Any help...

My buddy did a burnout last night at the top of my street in his stock 91 vert auto and then about a mile down the road his car died, LOL, but yea we need to fix it now. I pulled the codes with KOEO and got a code 96 which was fuel pump secondary circuit failure/high speed fuel pump relay open...

Ok, I got a job at a ford parts distribution warehouse, and I get all parts from ford at 10% above cost. Which is basically 75% off retail. So if anyone (which I know alot of people do here) need oem replacement parts for your ford, I will do the favor and get them for you and have them...

I just got a job at a ford warehouse and I get all motorcraft and acdelco parts 10% above cost which is like 75% off retail price. I just put my FMS B springs on and since lowering your car puts a bigger strain on all the other suspension parts, I was wondering if I could replace my shocks with...
