1988-1997 Stock Ford Truck Upgrades

TWISTED SMOG BOX

An EGR delete kit for 1988-1997 Ford trucks and Broncos with EEC-IV ECUs

** DOES NOT WORK WITH MAF **

These kits are designed for “off-road use” and will safely eliminate the SMOG, EGR, and un-needed vacuum sensors from the ECU.

Using the same approach as we take in our vintage stand-alone harnesses we are now able to do a full EGR, vacuum sensor and smog system delete kit for 1988-1997 Ford trucks and Bronco. This unit is essentially a switch that turns off the EGR and other un-needed sensor feedback to ECU. This allows the ECU and engine to operate flawlessly the way it should. In fact, it achieves better air fuel curves without the SMOG program operating. Additionally, our kit includes the belt to bypass the SMOG pump. With all of this combined you will make more horsepower, torque and allow the engine to get better gas mileage. Without our kit, if your truck has a sensor failure with any of these components, it will go into Ford’s EEC-IV “limp mode”, resulting in horrible gas mileage and a loss of power.

You can leave all of these components intact, or if you want to clean up your engine bay, you can remove them. If you need to go do emissions testing, simply remove the Twisted Smog Box and plug your system back in as normal. The other components only take about 10 minutes to swap back and go get emissions tested and be fully legal for “on-road use”. That being said, we always have passed tailpipe emissions even with the smog system eliminated.

** If you are planning on removing all of your SMOG tubing, purchase the SMOG pump tubing elimination hardware bundle option ** 

Included with this kit :

  • Twisted Smog EGR eliminator
  • EGR valve block off plate
  • Shorter Serpentine belt to bypass the SMOG pump ** We don’t include a belt with the 5.8 kit. 5.8 engines had three differing bracket types, you will need to purchase a belt from your local part store that fits your engine. **
  • All connectors and mounting hardware

Low Profile Throttle Bodies for the 7.5 liter 460

1988-1997 Ford trucks with EEC-IV ECUs

** DOES NOT WORK WITH MAF **

By swapping to this throttle body, you will get better throttle response, increased horsepower, and increased torque. Your engine will come to life and perform like the beast it truly is. This throttle body improved our 0-60 times by 2 full seconds. We did 12 runs with the original throttle body and this one just to confirm it.

** This one is NOT smog legal, and is intended to be used with Twisted Smog Box for an 88-97 **

If you want one that is 50 state legal, please see “Smog & Emissions Compliant Low Profile Throttle Body – 7.5 Liter 460” product.

There is no bracket to hook up cruise control with this unit.

Included with this kit:

  • Throttle body adapters
  • Holley low profile throttle body, throttle cable and all needed sensors
  • Idle air bypass and grommet
  • Grommet and elbow for the driver side breather tube

14" Round Air Filter Base for Low-Profile Throttle Bodies

This is only for the Air Filter Base, not a complete Air Filter. We find these to be the perfect fit for the low-profile throttle bodies. These have a ¾ “ rise needed to clear your fuel rails. There is a metal port that connects to the driver side breather port. We also drill and install a grommet for the idle air bypass. Take the guess work and the possibility of drilling your air filter incorrectly away, we will gladly do this step. Top this off with any 14″ round air filter of your choice, and lid of your choice.

Performance Modified Intake

We are proud to offer the only performance upgrade intake for 1988-1997 460’s. Whether you have built up your 460 or wanting more out of your stock motor letting it breath is always the answer to more horsepower and torque. Having seen the drastic performance increase with ported and balanced single plane manifolds paired with multi-port efi we had to give it a shot. The result was an instant and undeniably increase in powerStarting with Ford’s factory intake we start by cutting the stair-stepped bottom out. From there we remove all the internal passages. They are cut back into a balanced much short length. The air no longer has to get drawn through long runners that make sharp 90 degree turns. Instead each cylinder can now easily draw the air it needs to make the power a 460 is capable of. The easiest way to describe the difference is, instead of downshifting just lay into the throttle and watch the speedo climb. As always, we did 12 time trial pulls before and after the intakeThe difference was 1.75 seconds difference in 0-60 in the pictured blue and white 9000 lb. Monster. Everyone who has gone for a ride has said they all felt a huge difference. As the driver it feels like I just unhooked the flatbed trailer.

Depending on how quickly you need your new intake, there are two purchasing options:

Option 1: We don’t charge a core charge. You send us your intake for this service, and we verify that it’s usable. If it is, we send your new intake out the same day. Price includes S+H on delivery of your new intake.

Option 2: If you need your new intake faster, pre-pay the refundable core charge of $125. We will immediately ship your performance modified intake, simply send us your old one. Once we receive your intake in usable condition we refund the core charge fee.

Option 1: Without Core Charge

$440 (Includes S+H)

Option 2: With Core Charge

$565 (Includes S+H)

1988-1997 - FORD F-250/F-350 2WD/4WD 460 MOTOR MOUNT KITS

Ditch those squishy water bed style factory motor mounts. These Bullet-Proof motor mount kits will bolt directly in place of the factory mounts. Our goal was to make a quality mount that could handle high horsepower, keep your motor locked down and be smooth enough to use as a daily driver. These are built so well if there’s ever an issue, we replace them free of charge.

$168 (Includes S+H)

Bullet-Proof Motor Mount Kits

After having every motor mount we have purchased fail we decided to make our own. These are a fully caged polyurethane motor mount kits. They hold the engine absolutely stable but won’t vibrate you to death. They will handle high horsepower engines but are daily driver friendly. Ours are built at zero degrees with a stock nose up engine. Many other companies are not. Each of our mount kits are made of DOM tubing, polyurethane bushings, plate steel and grade-8 hardware. A pro-rated warranty is laughable. Simply put if these ever fail or wear out we replace them free of charge.
