Pro Turbo Kit
(Low Boost)
LC Engineering's Turbo Kits are designed for use on the Toyota 22RE-powered trucks, 4Runners. Whether for street or competitive drag racing, LC Engineering can configure a custom turbo kit for your specific needs. The LCE street turbo kit is designed to utilize our Haltech System or any other stand-alone engine management system. Along with larger injectors, the Haltech System can be programmed to provide the correct fuel and ignition curve for a performance turbo engine. Please make sure your engine is set up to handle boost before adding a turbocharger kit.
This street turbocharger is designed to spool quickly for maximum drivability in street vehicles. This turbo utilizes a 40mm external wastegate. The wastegate is set for 5psi, which is plenty for most street engines, but can be easily adjusted by swapping springs. This turbo will support up to 250+ horsepower, and can be turned up to about 14 psi while still being efficient. The base kit features a custom Garrett turbo with a tig-welded CNC-machined billet steel manifold, stainless steel down tube, charge pipe to connect to throttle body, and all the necessary gaskets, fittings, lines and hardware for installation. This turbo kit will require a stand-alone fuel management system like our Haltech System.

This turbo kit consists of the necessary parts to upgrade or add a turbo to your 22RE 4-Cylinder
Engine. This kit does require some fabrication to address your particular application such as
inter-cooler location, exhaust system layout and fuel management.
NOTE: This kit does not address the fuel injection management or ignition control concerns.
LC Engineering offers engine components and other accessories to modify your engine assembly
as needed to perform with this turbo kit. Please call our technicians if you have any questions on
your specific application at (928) 855-6341.
Remove Stock Components:
Remove exhaust manifold, down tube, heat shield, etc. from your engine.
Drain coolant from radiator.
Heater Tube Relocation:
If your vehicle has a heater using the stock water tube running along the exhaust side of the block,
you will need to modify the tube to clear the turbo down pipe. See the illustration for where to cut
the steel tube. Cut the rubber heater hose behind the valve cover (See illustration below for the
location). Install the supplied hose barb union (A), and run the rubber heater hose from that hose
barb union to the cut tube. Use supplied Adel clamp to secure the hose to the block where the
factory tube is mounted.
Turbo and Turbo Manifold Installation:
Install turbo manifold onto the head using the supplied exhaust gasket and the new exhaust stud kit (Tighten to 33 ft-lbs). LC Engineering has pre-installed the turbo onto the manifold, including the oil drain flange housing and oil feed fitting. Install the exhaust down tube onto the turbo using the 3 bolt gasket and hardware provided.
NOTE: Make sure your exhaust system is properly aligned with the down tube, to avoid side load on it.
Installation of the Turbo Oil Drain Line:
Factory Turbo Block:
The oil drain will be located at the stock drain location on the block. Using the supplied drain
housing and hardware, bolt it onto the stock turbo block then use the supplied drain line between
the turbo drain and the block drain housing. Use thread sealant on all of the pipe thread fittings, and
oil on all of the AN fittings.
Non Turbo Block:
The oil drain will have to be located on the oil pan just below the pan rail (Approx. 1.500” down).
Mark the location where the oil drain is to be located. Remove the oil pan and drill a hole where you
marked the oil pan. Weld the supplied fitting to the oil pan. From here you will debur, clean, paint
and reinstall the oil pan. Use the supplied drain line to install between the turbo drain and the drain
fitting on the oil pan. Use thread sealant on all of the pipe thread fittings, and oil on all of the AN
fittings.
Installation of the Oil Feed Line:
Factory Turbo Block:
On the exhaust side of the block, in the stock oil feed location, install the 12mm x -4AN fitting with a
copper crush washer. Install the stainless steel feed line coming from the oil supply fitting to the top
of the turbo oil feed inlet. Be careful to route the oil line away from as much heat as possible.
Non Turbo Block:
On the exhaust side of block, behind the motor mount location, remove the oil galley plug. Install the
–4AN x 28BSPT fitting to the block using thread sealant. Route the supplied oil line from the oil
supply fitting to the top of the turbo oil inlet fitting. Use the supplied Adel clamps to route the line
from the block fitting to the turbo. Mount the 90 degree side of the oil feed line to the block, and
then connect the straight end of line to the 90 degree fitting on the turbo.
Power Steering Hose Bracket:
We have supplied a special spacer to move the power steering hose out of the way when installing
the turbo. Install the spacer between the reservoir and the hose so that the power steering hose
clears the silicone hose. Bolt the spacer to the reservoir and use the supplied Adel clamp around
the power steering hose, while using the supplied Allen bolt to attach to the aluminum spacer.
Turbo compressor exit clocking position:
The compressor side of the turbo is adjustable, but should be clocked pretty close when you receive it.
Turbo Charger Compressor Hot Pipe Installation:
Using the 2” 90º hose connector and band clamps, install it on the exit side of the compressor. The
charge pipe is designed in two sections, to make the installation easier. Install the tube with the long
leg on the turbo side, and the short leg tube on throttle body side. Use the 2” silicone coupler to
connect the two halves (See image below).
Turbo Engine Set-Up Information:
Turbo charging any engine increases the strain on all of the engine components. At each level of
additional boost, new issues regarding engine configuration develop and need to be addressed.
Keep in mind that it is the combination of matched components that will deliver a reliable high
horsepower engine. What works for a low boost application may not take the strain of high levels of
boost. The following are some guidelines to consider when prepping an engine for a turbo
application.
Camshaft:
LC Engineering offers specifically designed camshafts to achieve full benefit of your turbo engine.
We offer custom ground camshafts for all levels of boost and rpm ranges. For the most low boost
street applications, our Street Turbo Cam (part # 1022027) is an excellent choice. Please call and
talk with our technical staff about your specific requirements and for a recommendation.
Valves, Valve Springs and Cylinder Head:
For the most performance, the valve size, valve springs and cylinder head porting need to match
the desired level of boost and the camshaft profile used. Our Pro Cylinder Head (part #1021024) will
be adequate for most low boost 4WD and 2WD street applications. For drag strip and high rpm use,
even at low boost levels, we recommend using our Stage 2 Head (part # 1021033) with Pro Dual
Valve Springs and Titanium Retainers. Our Pro Cam Kit (Part # 1020000) would be beneficial if you
are rebuilding your cylinder head.
Compression Ratio:
To achieve a reliable turbo charged engine, you will need to lower your mechanical compression to
the proper ratio. This can be done on a stock EFI engine by changing the pistons during the rebuild
process. We offer both a Street Performer Hypereutectic Piston Set, as well as our Racing Forged
Piston Set. These will help you achieve your desired compression ratio. Remember that Cylinder
head and block modifications are able to change the compression ratio. Always check your
components during assembly to verify the mechanical compression ratio. Please call our
technicians if you have any questions on your specific needs.
Short Block / Rotating Assembly:
The stock short block has an adequate strength for low boost and low rpm applications. For higher
levels of boost and performance, our Pro Short Block components (Pro Crank, Pro Rods, and
Forged Pistons) should be used. A Pro Short Block Kit (Part # 1011045) will provide adequate
strength for up to 300 HP. For higher horsepower levels or turbo/nitrous applications please contact
our technicians for specific recommendations.
Fuel & Ignition Management:
LC Engineering offers the SDS fuel management system that will control the fuel curve and Ignition
timing (LC Pro Fuel Injection Kits). Generally, you will need larger injectors and additional sensors
for higher boost applications. We also offer a Mass Airflow Conversion kit that eliminates the stock
air box assembly, and replaces it with a hot-wire style MAF sensor. We offer several kits with
various fuel injector sizes. Please contact our technicians for a specific recommendation.
Intercoolers:
Intercoolers allow the use of high boost levels and increased performance. There are many different
intercooler designs and locations for them. These units are available with different sizes and
configurations. You can find the different intercoolers we offer on our webstore
(www.LCEperformance.com). Please contact our tech line for specific information on the
intercoolers.
