Holley Sniper EFI System is Easy, Budget-Friendly Path to Fuel Injection

The throttle body looks remarkably like a Holley carb, which is great for anyone wanting classic looks and modern performance. Much of the system is encased right inside the throttle body—and that includes the ECU. It flows cfm and can support up to horsepower. Holley figured out a way to mount the ECU within the throttle body. Internally, the throttle body is fitted with four injectors just like the Stealth system. It incorporates a built-in fuel-pressure regulator pre-set at Fuel is delivered conventionally to the throttle body.

I am attributing that to my errors with the tape measure in my haste to get mine measured so I could get back into a warm house, and I am simply using the published specs. First up, let’s tackle overall length and case length. Overall length is important for the final driveshaft length and the case length is important for the fitment to the transmission tunnel. This will require shortening the driveshaft by a matching amount, so I know that no matter what I will be paying a visit to the local driveshaft shop, which I would be doing anyway – see the section on Inputs and Output for details on why.

That means the transmission should fit nicely without any major clearance issues.

Jun 18,  · Monster Transmission Presents Curt’s Corner as Curt goes over a Throttle Valve Cable(TV Cable) for a R4 Transmission. Curt covers everything from taking the .

The automotive world is increasingly regulated by digital electronics, and hot rodders might as well take advantage of these amenities. This story will look at the evolution of the 4L60E, which is essentially a digitally controlled R4. The original R4 was built in as a Corvette four-speed automatic with overdrive. This gearbox is different because it applies an overdrive to First gear to create Second.

Third gear is 1: This first version was designed with a bolt-on extension housing and employed a throttle-valve TV cable intended to signal engine load to the transmission via throttle position, instead of a using engine vacuum. Most transmission specialists agree an improperly adjusted TV cable is the culprit in most aftermarket R4 failures. The quickest way to identify a 4L60E is to first look at the bellhousing pattern.

In , GM wisely converted to electronic control, eliminating the cumbersome TV cable while changing its nomenclature to 4L60E. The numbers decipher like this: Later transmissions were upgraded as 4L65 and 4L70 for use in heavy-duty trucks. The 4L60E has now been in production for more than two decades and has experienced multiple performance updates that affect interchangeability.

LT1 Wiring for dummies

Here’s how I interpret the circuit: Follow the Purple wire and select a good place to splice a 12v switch into it. When this switch is in the “off” condition the TCC will not engange at all.

Salvation for the anemic TR7.A John’s Cars conversion will provide you with the oomph you deserve (more than a “TR8”) and saves your Triumph from being on the way to the lonely boneyard. Don’t feel as if British Leyland built the only four-cylinder Titanic, GM had the Vega.

It was introduced to the larger car B-body and similar and truck lines as the TH R was introduced to the car line. The was given a “universal” bellhousing bolt pattern for its ability to bolt to different engines both the Chevy and B-O-P-C engines. The came in two bellhousing bolt patterns — the standard “Chevy” which includes all smallblock engines from to cubic engines and the later “Vortec” series engines and their derivatives , the big blocks from the truck only to the , and the new ZZ This bellhousing pattern was also used for the 6.

And then there was the smaller bellhousing bolt pattern used on the 2. The 2WD had a longer tailshaft and a housing including a bushing to support it along with containing a speedometer drive housing. The 4WD version had a much shorter tailshaft which was to be supported by the adapter and transfer case input shaft bearing, the 4WD speedometer was driven from within the transfer case rear output shaft housing.

The only other difference I have found here is that the torque converter cover dust cover for the 4WD version was made of cast aluminum instead of stamped steel or molded plastic, and it used much larger bolts to attach to the transmission, as it also made provisions to attach strut rod reinforcements from a bracket that mounted under the motor mounts to the lower portion of the cast aluminum dust cover.

There were also a few changes made to the V-8 model to give it the ability and dependability to be installed into the Chevrolet Camaro and Corvette — and in certain cases the Corvette version received even more enhancements. There were various differences in the same model — transmissions needed to be able to be used with the different engines and the same transmission; obviously the inch V-6 will have a bit of a problem driving the that was designed to be bolted behind a 6.

700R4 Transmission – Must Have T.V.

Converting from gas to diesel or from one brand of oil-burner to another is also enticing because of the ever-increasing availability of adapters, kits, standalone computers, and wiring harnesses that facilitate using various modern diesel-repower combinations to fit a wide variety of trucks and SUVs. The diesel-engine mating game has never been more fine-tuned. If you want to repower an older Jeep, Ford, Chevrolet, or Toyota with a Cummins engine, there are sources for the engines, adapters, and complete conversion kits that make it happen.

It takes time, knowledge, and patience.

Early production was a Gen3 engine in the “classic body style truck” Please let me know if PCM does not match the engine exactly. GM used different injector sizes, fuel rail types etc across engine’s and years. It’s important for best performance to know exactly what the engine is. Also, if you plan to swap intakes from another engine LS1 intake on a 5. Supplying an 8 digit injector number found on side of each injector will always help insure correct flow rate is programmed into the PCM.

Salvation for the anemic TR7. This conversion kit uses the rear-wheel drive 90? A converted TR7 is approximately 85 pounds heavier, so I supply a set of specially wound front springs.

The transmission gave up in my K Luckily a buddy had a 2wd r4 that we were able to get hooked up until we rebuild the old one. Only problem is speedo runs off a different plug so I bought this figuring I’d just learn where the shift points are and figure out speed that way.

Its Chevrolet Ram Jet crate motor is shifted by a R4 trans with a 2, rpm stall-speed converter. A Chevy Ram Jet transfers torque through a R4 automatic overdrive to a 3. Although the rod was spirited around town, highway driving was a pain. And since Fourth gear sustained cruise rpm is higher with a non-lockup converter, gas mileage decreases, partially negating the benefits of overdrive.

Nearly 22 years ago now. Today, it has 95, miles. A large percentage of that 58, mile difference has been off-road in the Pacific Northwest.

Transmission fluid cooler lines: on the R4 the bottom fitting on the right side of the transmission is the “out” line to the cooler and the top fitting is for the return line from the cooler. These fittings are 1/4-inch pipe thread, and CAN include an adapter from the factory for threaded steel lines in an SAE size.

Motochris’s Photo Album New Demon “Street Demon” cfm carb Just thought I’de share my thoughts about this new carb since there seems to be little info on it out there so far. I went thru all the typical BS with trying to tune the stumble that carb is known to have. Ended up way rich on the primary jets, plus a good amount of tuning to the accel pump to get most of it away. It wasn’t perfect by any means, but it was something you could deal with.

Stomp on it and it was great.. The fuel milage sucked with the primary’s as they were too. I have had good luck with the Edelbrock carbs and drivability and was planning on going that direction, just never got around to it over that last year or two. I saw the ad for this new Street Demon and it looked like it might fit the bill.. You can look at the ads for the carb to see all the details.

The Diesel Registry is for those that have installed any kind of diesel motor in their Suzuki Samurai, Sidekick or Geo Tracker. The purpose of the registry is to promote a Suzuki diesel community and to share information.

Some of these are discussed below. This engine has been used extensively in performance and race applications, and as such, there are many hop-up parts and accessories available for the it. The Buick V6 is a bit smaller and lighter than the Chevy or Ford V6s, but is somewhat heavier than the 3. Some Buick V6s odd ifre I believe have a moderate vibration problem and may tend to run a bit on the hot side. There is also a turbocharged version of the Buick engine that provides quite a punch for a light truck.

However, be cautioned that such a swap requires careful thought to obtain adequate engine cooling especially in cases where the truck will be driven slowly or for some reason have limited airflow. Modification of the exhaust, truck frame, and body will most likely be needed to get this engine to fit. This engine came from the factory in several configurations including: This is a torquey engine, and uses the same block design as the small block Chevy less two cylinders.
