Fly Wheel

Our flywheel is a brand new 27lb billet steel direct fit drilled flywheel designed to correctly fit the 1UZ/2UZ crank bolt pattern. The flywheel is 5 pounds heavier than a stock 3vz cast flywheel. This flywheel will provide more low end torque and maintain better engine speed while on and off road. This flywheel is designed to use a commonly available 3VZ pressure plate with the 3.4 throw out bearing for proper engagement of the clutch. Our flywheels are designed, machined and built in the USA.

We have a run of seconds on flywheels. Please see our New, Used, Demo page for details!

Clutch Kit   

Duel Comp Clutch Kit 3VZ 1988-1995 (9 1/4″)

This was developed for both street and off-road racers requiring a more aggressive clutch without giving up every day drive ability. The key to this kit is the clutch disc. One side has metallic pucks for a positive hold and the other has our Pro clutch fiber lining providing a smoother engagement to retain drive ability.
We recommend this for street vehicles with high horsepower engines. This clutch is stiffer than stock, but not as stiff as our metallic clutch kit. Clutch kits come with the pressure plate, clutch disk, pilot bearing, modified 5VZ throw out bearing, and a new alignment tool. You will need the 3vz pressure plate and the  throw out bearing from a 5VZ for proper clutch engagement. This kit puts all those parts together for you in nice package and takes the ordering of multiple items away and saves you money over ordering them separately.

2100lb clamp force /HP limit 385 / Torque limit 385 ft. lbs.

Clutch kit to include: disc, pressure plate, pilot bearing, throw out bearing $429 item number NWT-02 plus shipping

Replacement throw out bearings $89 item number NWT-03 plus shipping

Motor Mounts:  

3.0 3VZ to 1UZ motor mounts. After several attempts to build a one size fits all 1UZ motor mount for both IFS and SAS trucks, we  built the perfect mount for the 1UZ in the tight Toyota engine bay. This mount is completely bolt on! This mount places the engine as far back in the engine bay as possible to leave room to work at the front of the engine, and up high enough as to allow engine to fit with IFS rigs. This kit does require slight modification of the steering relay rod, transmission cross member, and a small 1″ body lift is required. You must also use your 3.0 isolator pads. These are shipped in raw steel. Our motor mounts are designed, machined, and built right here in the USA.

Motor Mount: $199 item number NWT-04 plus shipping. Please specify V6 or 4cyl as original engine in vehicle.

Under hood fuse wire kit
Toyota usually placed the main under hood fuse box on the right passenger side of the vehicle up on the inner fender. Originally the battery was located right in front of the fuse box and made applying power easy. Most of the time after an engine swap the battery and air box have to swap places. For this instance we offer a complete kit including the following items to make this power supply swap easy.
Our kit includes 5′ of 8 gauge multi strand copper wire, 8 gauge butt connector and 8 gauge 5/16″ eye connector, heat shrink tubing, and 5′ of conduit to complete the install.

Cross Member/ Belly Skid Plate   

Transmission cross member and skid plate. Our motor mounts do require either a modification of the transmission cross member as the tranny is located approximately 1″ back from its stock location or you can use the factory transmission isolator and a new cross member that accepts the factory isolator. No modification or fuss!  Our cross members and skid plates are designed, machined, and made right here in the USA. This is the transmission cross member you will want when using our motor mounts! This cross member is lifted 1″ over a stock Toyota cross member and includes a belly skid plate. Slight skid modification is necessary on IFS rigs that retain the front sway bar.

Cross members: $419 item number NWT-017 plus shipping.

Headers   

Most headers or exhaust manifolds offered for a 1UZ/2UZ need to be cut up and re-welded to try and fit the in the mini Toyota engine bay, they foul out on the frame. If your looking for a 1UZ/2UZ specific block hugger style exhaust header we have you covered. We have a header that will fit into the tight Toyota engine bay specifically with our motor mounts. These headers are engine specific, they fit without modification to the headers themselves, but these are a very tight fit. Patience is required for installation. These will fit IFS rigs, but they really shine of rigs that have a SAS done. Here are some spec’s below. Some rigs with large ribbed steering intermediate shaft may interfere slightly with headers. We recommend that a straight shaft rod replace the ribbed rod.  For this we offer a  weld in place 3/4 smooth coupler that welds onto the rag joint end and the upper rod end. To connect the two our kit includes two 3/4″ smooth bore to 36 spline coupler and a 36 spline 12″ shaft.

These are not CARB approved! Off Road Use Only! If you want to run EGR then a bung connector will need to be made in your exhaust where it connects to the cone.  Any exhaust shop can weld in this simple bung.

Toyota Lexus 1UZ-FE/ 2UZ-FE V8 4-1 Block Huggers. These are a beef 1/2″ flange at the head, ceramic coated piece of awesomeness!!! We use factory Toyota style connecter gaskets so spare’s are easy to source should ever need to remove the exhaust from your rig.

1UZ/2UZ Block Hugger Headers $749 NWT-018 plus shipping

Steering shaft upgrade NWT-019 $109 plus shipping


Crossover Pipe Kit

For those who are wanting to install our headers we now offer a weld together cross over pipe kit. This kit features 2.25″ mandrel bent aluminized steel tubing. Our kit comes with all the necessary bends to get the headers to merge together in a 2.25″ input to 3″ outlet merge collector. Our kit has flared ends so the whole system slips together prior to welding.  With this kit and our headers you will get a custom cross over pipe for a fraction of the cost an exhaust shop would charge. This kit will place the cross over under the transmission and dump out on the driver side of the vehicle. When combined with our belly skid plate the cross over will be fully protected while off road!

This kit does require the final installer to grind and weld to get the cross over complete and functional.

Fuel Lines   

Braided Stainless fuel line. After you have put your engine in your Toyota you will find that the fuel inlet line is down on the passenger side frame rail. The fuel inlet on the 1UZ is on the driver side of the engine. We have designed a hose that will thread into the stock Toyota fuel line and also thread into the stock fuel inlet on the 1UZ side.  In some instance’s Toyota used a union down on the passenger side frame rail. You will need to make sure you have a male side 14M nut on the fuel line. This fuel line will work for those who have inline filters such as the V6 model Toyota. If your rig was originally a 4cyl truck then you will need the line that has a built in Fuel Lab 10 micron rebuildable filter.

Note: The original hard line on the 3VZ vehicles varies between Male, Female and Male w/ a F-F union. You will need to check and see what fitting your original hard line has in place. If you have a F end or M end w/ a Union from the factory, then the standard hose will
work. If you have a Male end only, you will also need a F-F union.

1UZ to 3VZ standard high pressure hose that fits to factory 1uz fuel hose found on engine NWT-021 $81 plus shipping

1UZ to 3VZ standard high pressure hose that fits fuel rail to frame rail. This is a complete hose eliminating 1uz inlet hose. NWT-021A $99 plus shipping

Intake Boot   

For those looking for a clean looking intake system we recommend that an air box from a 1992 thru 1994 SC400 be used. This air box is small enough to fit the engine bay and make your install look factory. Once the air box is installed you will need a pipe to connect the AFM to the throttle body. For that we have a custom fit silicone elbow. This elbow is made of the highest silicone available and comes with stainless steel band clamps These aren’t your auto parts store clamps that swell  and pinch the hose. Our clamps supply full clamping pressure around the whole hose, so no air leaks unfiltered into your engine. This elbow is contoured to slide onto the AFM with ease and then provide a nice snug fit onto the throttle body. Best of all it looks great!!!! The SC box requires slight modification with trimming before it will fit correctly.

EGR Delete

EGR exhaust block off plates. If you want to delete the crack prone EGR pipe to test EGR function, then these are for you. The EGR pipe connects from the back of the 1uz head to the exhaust manifold and these plates block off both of those ports. These plates are for testing purposes or off road use only! They are in raw steel
