Next Batch ETA 4/08.
Our new high performance fuel rails are designed for use with other OE or aftermarket high-flow fuel injectors. They are manufactured from extruded aluminum fuel rail stock and permit installation of very common 11mm import bosch and lucas style top-feed o-ring fuel injectors. With .500" inside diameter and -6AN fittings the pair will support well over 1000 horsepower when run in true parallel and over 700 horsepower in series. They are machined with a specially chamfered end and tapped for the included high pressure -6AN O-ring boss fittings, as opposed to using NPT fittings and teflon tape. Rails are made for either early "top-feed" injector (or 84-86NA and 84-85T) style lower intake manifolds, AS WELL AS later "side feed" 87-89 style with modification performed at no charge. As always, the fuel rails are available hand-polished for a small $10 charge. If you desire a mirror-like finish, special finishing and polishing can be provided at additional cost (contact for details).

camgears

Russ' Adjustable Cam Gears - US $249 + $50core (In Stock)
Free Shipping to cont. USA!
Available in RED and BLUE for VG30 and VG33

Red: sh
Blue: sh

EXCLUSIVE part, Now Available For both VG30 and VG33!These cam gears are precision machined stock gears with replacement aluminum hubs. The use of an unprecidented 8 bolts to secure the hub assures they will always stay in the set degreed position and never “slip”. Adjusting camshaft timing up to +5 and -10 degrees has never been easier or more accurate! No other adjustable cam gear on the market offers this adjustment ability or versatility.

Changing cam timing "shifts the powerband up or down". Generally speaking, advancing cam timing yields more mid-low range torque, while retarding cam timing yields more high end horsepower. See for yourself with the dyno graphs here. Contact me to request VG33 round tooth style, otherwise order is default for VG30 square toothed style gears. Made In The USA

warningEFFECTIVE 12-06: $50 cam gear core fee charged at time of purchase. We prefer cam gear cores to be sent in advance with a money order, but the links above will allow you to purchase a set if you can't have any vehicle downtime. Contact for information.

Oil Pressure Sender Adapter Fitting - US $11
warning(OUT OF STOCK)
Free Shipping to cont. USA!

 

sh

Adapter fitting for installing an aftermarket oil pressure gage on your engine. Most aftermarket gages come with 1/8" NPT fittings which are not the correct thread pattern for the oil sender location. This adapter allows you to install the aftermarket pressure fitting to the stock location with ease!


magnetic oil drain


Magnetic Oil Drain Plug - US $11 (In Stock)
Free Shipping to cont. USA!

 

sh

This replacement magnetic oil drain plug will collect small metal particles from your oil and prevent them from being circulated in the engine. This can prolong the life of your oil pump and your engine! You can also take a small 'look' at an indication of the internal condition of your engine every oil change!

Throttle Body Spacer - US $20 warning(OUT OF STOCK)
Free Shipping to cont. USA!

 

(60mm TB) sh

Phoenolic-type spacers for isolating throttle body temperature from that of the upper intake plenum. Used either to further decrease intake charge temperature combined with our plenum spacer, or to insulate the intake plenum from heat while the coolant lines to the throttle body are left in place.

spacer


VG Intake Plenum Spacer Kit- US $79 (In Stock)
Free Shipping to cont. USA!

sp

This machined phoenolic-type intake plenum spacer provides a barrier for heat from the lower intake manifold to enter the upper intake plenum. Heat transmitted into the aluminum upper intake from the lower intake heats the intake air and reduces the engine's power potential.
-Preliminary tests have shown between 20 and 83 degree F drops in intake plenum temperature, depending on conditions.

-The 3/8" thickness also increases the intake runner length by the same 3/8" (.375").
-
Also removes the requirement for a gasket between the plenum and lower manifold.

170F/77C Low-Temp Thermostat- US $20 (In Stock)
Free Shipping to cont. USA!

 

sh

Enhance performance easily without losing notable fuel economy. A high quality 170 degree temperature thermostat will keep the entire engine running cooler, but without the larger reduction in fuel economy than the very expensive NisMo 160 degree thermostat will cause because of the ECCS's temperature enrichment. The reduced charge air temperature and reduced chamber temperature effected by use of a cooler thermostat will result in gains in power at all RPM, along with additional safety form a raised detaontion threshold.
