TURBOCHARGERS:

If your turbo isn't happy, then nobody's happy. Given the stress and operating conditions that these little puffers operate within, it's a wonder that they last as long as they do.

We stock freshly rebuilt stock Mitsubishi TC03A original turbo units, available as both stock and performance-upgraded versions that allows you a simple, bolt-on solution to your turbo woes.

NOTES:

- all rebuilt turbocharger units are sold on a trade-in basis, with a refundable core charge fee applied (which will be fully refunded upon the return of a stock, factory, complete, un-damaged turbo unit). Rebuilt turbo units carry a 1-year (from date of purchase) warranty against defects in workmanship and materials only, subject to inspection and analysis of any failed unit.

- these rebuilds are for "street" bikes, and not for drag or road-race use. Performance-upgrade units feature a slightly larger, more efficient compressor wheel, and/or a ceramic-coated turbine housing (the retention of as much exhaust heat as possible is the key to extracting more efficiency from your turbo).

- all units should be used with the factory wastegate-control vacuum actuator. For even greater control and performance enhancement, use the HCP17910 or HCP17911 BOOST CONTROLLER module.....it's easy to install, tune, and tailor to your unique riding conditions and style!

- a great review of some of the operating characteristics and problems inherent to the Yamaha XJ650 Turbo bikes can be reviewed at:

http://www.turbomotorcycles.org/TMIOA/TechHelp_Yamaha.html


A common problem with the turbo units on this bike is the small pressure relief valve situated at the front of the engine, just off to the left side of the oil filter element boss (on the crankcase). This spring-loaded "ball bearing" check valve is supposed to prevent oil supply to the turbocharger when the engine is off. If this check valve fails into the "always off" position (eliminating or reducing oil supply to the turbo), you'll burn up the turbo bearings mighty quick (like within a minute or two of operation). If the check valve fails in the "always open" position, it will allow a continual supply of oil to the turbo (even when the engine is off) and can result in a significant puddle of oil under the turbo unit (failure of the copper crush washers at the turbo oil supply inlet pipe can also cause this issue, but typically this type of failure will result in only small drops of oil under the turbo, whether then engine is running or not).

If these situations are detected, the pressure relief valve must be serviced (no replacement is available) and be internally cleaned out of gunk, grime, crud, crap, and what-not. It's kind of a bear to get to, and may require exhaust system removal, but it is an important part of regular turbo system maintenance:

Stock Rebuilt Turbocharger:

These units will provide the same level of performance and boost as the factory-equipped turbo unit, whether used in the stock 1982 configuration or with the 1983 version with the "Power-Up" boost enhancement kit. Note that neither the EXHAUST MANIFOLD nor the wastegate VACUUM ACTUATOR UNIT are not included with any of the turbocharger units and should be ordered separate if needed.

HCP17822 Rebuilt OEM TURBOCHARGER. Stock rebuild perfectly replaces your worn out or leaking original unit. NOTE: a refundable core charge will be applied to this part, and requires the delivery to us of an original stock, complete, un-damaged turbo unit.
$ 795.00 + refundable $ 300.00 core charge.

HCP18165 Rebuilt OEM TURBOCHARGER. Enhanced stock rebuild perfectly replaces your worn out or leaking original unit. On this version, the turbine (exhaust) housing has been ceramic-coated to help retain as much heat as possible, thus increasing the turbo efficiency, reducing lag times and creating full boost at a lowered rpm. NOTE: a refundable core charge will be applied to this part, and requires the delivery to us of an original stock, complete, un-damaged turbo unit.
$ discontinued



Upgraded Rebuilt Turbocharger:

These units will provide an increased level of performance and boost as compared to the factory-equipped turbo unit, whether used in the stock 1982 configuration or with the 1983 version with the "Power-Up" kit. A slightly larger, more efficient compressor wheel results in less turbo lag, and quicker spool-up, resulting in more boost at any given rpm's up to the maximum pressure.

It is strongly recommended that the aftermarket BOOST CONTROLLER module be used in conjunction with either of these upgraded turbochargers to allow the ultimate in performance. Your carb fuel circuits will almost always need to be enriched by 2-4 jet sizes over stock.

Note that neither the EXHAUST MANIFOLD nor the wastegate VACUUM ACTUATOR UNIT are not included with any of the turbocharger units and should be ordered separate if needed.


HCP17823 Rebuilt OEM UPGRADED TURBOCHARGER. Performance rebuild perfectly replaces your worn out or leaking original unit. NOTE: a refundable core charge will be applied to this part, and requires the delivery to us of an original stock, complete, un-damaged turbo unit.
$ 995.00 + refundable $ 300.00 core charge.

HCP17913 Rebuilt OEM UPGRADED TURBOCHARGER. Enhanced performance rebuild perfectly replaces your worn out or leaking original unit. On this version, the turbine (exhaust) housing has been ceramic-coated to help retain as much heat as possible, thus increasing the turbo efficiency, reducing lag times and creating full boost at a lowered rpm. NOTE: a refundable core charge will be applied to this part, and requires the delivery to us of an original stock, complete, un-damaged turbo unit.

Upgraded Stock Exhaust Manifold:

As we mentioned before, one of the key ways to boost the efficiency (and thus performance) of your turbo is to capture and retain the heat energy in the exhaust system............after all, that's the whole point of a turbocharger, to take the "wasted heat" content of the exhaust gas stream and make it do something useful (turn a turbine wheel which can then be used to compress the intake flow thru the carbs and into the cylinders). Thus you want to "capture and retain" as much of that exhaust system heat as is possible.

These ceramic-coated EXHAUST COLLECTOR MANIFOLDS are the perfect way to accomplish this heat retention. These are original factory manifolds that have been inspected, cleaned, and then ceramic-coated with a durable, satin-grey finish.

NOTE: all upgraded exhaust manifolds are sold on a trade-in basis, with a refundable core charge fee applied (which will be fully refunded upon the return of a stock, factory, complete, un-damaged exhaust manifold).


HCP17915 Rebuilt OEM CERAMIC-COATED EXHAUST MANIFOLD. Enhanced performance stock exhaust manifold which has been ceramic-coated to help retain as much heat as possible, thus increasing the turbo efficiency, reducing lag times and creating full boost at a lowered rpm. NOTE: a refundable core charge will be applied to this part, and requires the delivery to us of an original stock, complete, un-damaged turbo unit.
$ 279.00 + refundable $ 175.00 core charge.




TURBOCHARGER REPAIR AND SERVICE PARTS:

Well, there's nothing like a little tiny huffer to make an engine scream, and Yamaha was one of the first and most successful at that game with the introduction of their XJ650 Turbo Seca model in 1982. And not wanting to rest on their past achievements, for 1983 they upgraded the turbo system to allow the creation of 12 psi of boost pressure (up from 7 psi on the 1982 models), and even offered a Power-Up Kit package to all 1982 owners to upgrade their turbo system to the higher boost pressure created by the more powerful 1983 models.

We've got the proper TURBO REBUILD PARTS needed to replace or repair the various turbocharger components. Please note that the oil supply and oil scavenge line parts are located in other sections of the catalog.

NOTE: it is imperative that the turbo wheel/shaft assembly be re-balanced after a rebuild or catastrophic turbocharger failure may occur!



Turbocharger Rebuild Kits:

tc1) Aftermarket turbocharger REBUILD KITS contain all the necessary parts to properly rebuild an original turbo to stock specifications. NOTE: turbine and compressor wheels, housings, and some other components are not available. Only the standard replaceable "wear" parts are included in the rebuild kits.

Turbochargers are hardy little items, but do require periodic rebuilds. The shafts and vanes must be balanced as a unit. If you are unable to perform this service, we suggest that you have the turbo rebuild by a shop experienced in performing such work or purchase one of our fully rebuilt turbo units.


HCP24159 Aftermarket TURBO BASIC REBUILD KIT contains all of the typical "wear" items that will be needed to refresh a factory turbocharger. Includes the pistons rings (2), shaft bearing/oil valve, thrust bearing, thrust collar, seal plate, seal plate o-ring, compressor housing o-ring, shaft locknut, and the oil line gasket.

TURBO OIL SYSTEM:

The oil pressure and return lines for the turbocharger endure an amazing amount of heat, and as such, are likely to suffer from deterioration and failure. The turbo unit uses a "floating" bearing design that allows the impeller to spin up to----get this!----220,000 rpm's, and it's life depend entirely upon its bearing getting enough oil to properly "float". This requires adequate volume and pressure of oil......so leaks anywhere in this system are frowned upon in a very critical manner. Below is a selection of the proper O-RINGS, GASKETS, and HARDWARE pieces necessary to insure all is well with these crucial lines.

The parts list below starts at the "beginning" of the oil flow, at the oil filter housing, and works its way through until the end, where the return line terminates at the scavenge pump.

Use 1 per engine on all XJ650 Turbo models. Each:
$ 24.95

HCP24266G Aftermarket exhaust system TURBO WASTEGATE OUTLET-to-RIGHT MUFFLER JOINT PIPE INLET GASKET. The round gasket is made of an aramid graphite material and does not feature the original metal “fire ring” around the central hole as original. Aramid graphite is a strong, high-temp material and is a good, less-expensive substitute material to use for this application, as this right side portion of the exhaust system is only active during pressure pops when the wastegate is activated (to bleed off excess pressures). Of course, if you’re redlining in every gear and/or have a modified wastegate - boost controller system that regularly is going to run up to really high system pressures, then we recommend the original metal style gasket (HCP24266M) above to prevent blowing out this graphite gasket (this graphite material is not nearly as resistant to high pressures as the original style metal gasket is) Use 1 per engine on all XJ650 Turbo models. Each:
$ 11.95



HCP2624 OEM exhaust system TURBO JOINT PIPE-to-RIGHT MUFFLER CAN INLET GASKET.

Turbocharger Vacuum Boost Controller:

Get the maximum control and power out of your turbo system with the use of an easy-to-install, compact BOOST CONTROLLER MODULE. About the size of a pack of cigarettes (about 2-1/2" long x 3/4" thick), these "dial-a-boost" units manage the opening rate and timing of the wastegate operation, thus allowing you to tune the boost response of your system to operating and environmental condition.

Here is some good information about the Yamaha turbo system, including the pop-off valve settings, the factory "power-up" kit, and using an aftermarket boost controller:

NOTE: the use of a wide-band O2 sensor is recommended when tuning for maximum power output of any turbo system, but especially with the use of a boost controller.
