NWT specializes in V8 swaps for Toyota trucks – new and used, USDM and JDM. We work on the FJ and Land Cruiser, (FJ40, FJ50, FJ60, FJ70, FJ80, FJ110 and 200-Series), 4Runner, HiAce van, Hilux, Surf, Taco and Toyota Pickup.
If you’re doing your Toyota-V8 swap at home, NWT’s experts know the parts you need. We’ll get you to done – you CAN build your own 1UZ, 2UZ, 3UZ, 5VZ, 2/3RZ or 1/2UR-powered rig.
While we list as many parts as possible, there are always new designs coming in (often at our customers’ behest). If you have questions about what your swap requires, or seek parts you can’t find, just ask – we are happy to help.
NWT has extensive experience with swapping the 1UZ, 2UZ and 3UZ V8 into Toyota trucks. Contact us and we’ll guide you to the parts you need to get your rig running right.
For specific information about any of our swap products (flywheel and clutch kits, bell-housings, radiators, wiring harnesses, motor mounts, et cetera), visit our installation-instructions page. We’re always writing up more product installations, and if there’s one you’d like to see, please ask.
If you need additional assistance with installation or customized fitment, send us an email with exact details (we like to keep track), and we’ll respond ASAP.
Billet-Steel Flywheel for 1UZ, 2UZ and 3UZ Swaps
Our billet flywheel is a new 27lb steel unit that bolts directly to the 1UZ, 2UZ and 3UZ crank-snout – without modification (like a good flywheel should). The flywheel is five pounds heavier than a stock cast-iron 3VZ flywheel, expands low-RPM torque, and improves your ability to maintain engine speed while driving and crawling. This flywheel is compatible with 3VZ pressure-plates but requires a 5VZ (3.4-liter V6) throwout bearing.
NWT’s flywheels are designed, machined and built in the U.S. of A.
Flywheel NWT- 001 – $439 plus shipping
Dual Comp Clutch Kit 3VZ 1988-1995 (9 1/4″)
This clutch was developed for off-road racers who require more clutch pressure, but it’s friendly enough for everyday use. The key is the hybrid clutch disc – one side has metallic pucks for increased holding capacity, while the other uses an NWT-spec fiber-based lining that supports smoother engagement.
NWT recommends this clutch kit for multi-use vehicles (on and off-road) with improved-horsepower engines. It’s stiffer than stock, but not as stiff as our high-metallic clutch. NWT clutch kits come complete with a cast-iron 3VZ pressure plate, clutch disk, pilot bearing, modified 5VZ throwout bearing, and an alignment tool. This package puts all those necessary parts together, and saves money compared to ordering individually.

1UZ, 2UZ & 3UZ-Swap Motor Mounts
Following a rigorous development process, NWT has created a bolt-in 1UZ/2UZ/3UZ motor mount that works for both IFS (independent-front suspension) and SAS (solid-axle suspension) Toyota Pickups (pre-Taco) and first and second-generation 4Runners. This one-size-fits-all mount locates the 1UZ engine in the ideal spot in the Toyota engine bay: as far back as possible (leaving room at the front of the engine), and high enough to allow the 1UZ to fit IFS rigs. These mounts replace the OE Toyota units, bolting directly to the engine and frame. Vibration is damped by the mounts’ polyurethane bushings (request red or black when you order – there is no difference in stiffness), so no isolator pads are required, and nor are parts of the old mounts.
NWT’s motor mounts are designed, machined and built in the U.S.A., and ship painted black.
Note #1: As with any engine swap, there’s going to be a few modifications necessary (quit whining: this is still an easy swap). The kit anticipates mods to the steering-relay rod and the transmission cross-member, plus a one-inch body lift.
Note #2: 1UZ, 2UZ and 3UZ swap-mounts for Toyota Tacomas and the third-generation 4Runner are on their way. Call and ask for an update.

See below for product and ordering details – NWT has them for $259.
Build-Your-Own 1UZ, 2UZ & 3UZ Swap-Mount Fit-Kit
Custom engine installations can require exact – and particular – engine placement. For those builders who want to position the engine forward, backward, left, right, up or down, NWT has your solution: a modular engine-mount kit.
We’ll do the hard work of tooling, cutting and shaping the engine and frame plates as well as the laterals and gussets, and we’ll source the correct bushings and bolts for you. All you’ll need to do is hang that engine in place, bolt up the plates, and weld in the laterals and gussets as you see fit – key word “fit”. This kit includes the CNC-cut engine and frame plates, bushings, nuts, bolts and washers. Also specify the original engine and chassis (such as 22RE, 3VZ or 5VZ, 3RZ, second-generation 4Runner, FJ40, etc).
Note #1: You’ll be accountable for your decisions on what goes where with this kit – NWT only warranties the quality and fit of the unassembled parts. If you’re not an experienced welder, NWT suggests you have a competent fabricator check your work post-facto.
Note #2: The swap-mount fit-kit is configurable for custom or specialized body and engine combinations, so call and ask us about your setup.

1UZ/2UZ/3UZ-to-R150 Five-Speed Bell-Housing:
NWT has a cast-aluminum bell-housing that mounts the Toyota R150 five-speed manual transmission (as found behind your 3.0-liter 3VZ and 3.4-liter 5VZ engine) to the 1UZ/2UZ/3UZ engine. This bell-housing includes the main housing (ahem, the “bell”), the front input-extension and the pivot mount. The slave-cylinder mount-pad is oversized so builders can customize the fit of their slave cylinder.
Note: While the mount-pad is pre-drilled for typical Toyota slave-cylinder options, you may need to trim, re-drill or re-tap new holes if you choose to use a non-standard slave cylinder.

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-021 plus shipping.
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.

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.

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. This union now comes standard with every purchase.

If you need just the F-F Union fitting to connect fuel line, we offer that as a separate item. NWT-029 $12.99 plus shipping
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.

1uz non-VVTI super charger manifold
This supercharger manifold will bolt to the factory lower intake manifold on all pre-VVTI Toyota / Lexus 1UZ-FE V8 engines.
These units are cast from aluminum and face machined only and make use of the existing cross flow characteristics of the lower intake manifold which some believe promote smoother air distribution between the cylinders.
We have 2 top plates on offer , one for the SVT M112 and the other for the popular SVT500 M122. Note that we have designed the intake ports to be slightly oversized to allow for any fluctuations in the casting shrinkage which happens during the manufacturing process so port matching to your lower manifold is recommended.
These units are perfect if you are building on a budget or if you just want that look of having a charger popping out of the hood as these sit slightly higher than the factory upper intake manifold once a charger is fitted.
UNIT DIMENSIONS: 377mm x 215mm x 45mm (excluding top plate)
AVAILABLE IN ANODIZED BLACK

MLS Cometic Head Gaskets
If your looking for the best head gasket available or wanting to change compression ratios for boosted applications we have you covered.
In most cases, we recommend 1.3mm head gaskets on 1UZ (1.0mm on 2UZ) and if you are running custom compression aftermarket forged pistons. If you are keeping the stock pistons and looking to lower the compression ratio for more boost, we recommend a thicker head gasket such as 2mm. This is for BOTH head gaskets.
The 1UZ version of the head gaskets is specifically for the non-VVTi engine and does not surround the oil port going to the VVTi solenoids
Cometic Head Gaskets are developed with the performance enthusiast in mind. With so many individual requirements for each engine, Cometic offers a number of options to suit your specific build and needs.
The Cometic MLS gasket is comprised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, its ability to rebound, and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material (Viton) designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. The Viton coating is heat resistant to 2500C or 4820F.
The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.
The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.
