Oil Temperature Adapter (VG, RB Engines) |
||
| Now Available! Until now, nothing was available to adapt the stock bung in the oil pan of turbocharged VG and RB engines to a standard 1/8" NPT temperature fitting short of using multiple adapters which would extend out and position the temperature fitting far away from the pan. These custom fittings are manufactured to allow the temperature fitting to be easily installed in the best possible location. Please make sure your gauge uses a 1/8" NPT temp fitting, if it is larger, modification of the oil pan may be necessary Made In The USA |

Multi-Layer Stainless Head Gaskets, SOHC VG Engine |
|||
| Now Available! I am very pleased to announce that the Z31Parts MLS Head Gaskets are now available. Numerous sets of the new MLS head gaskets for SOHC VG engines have been thoroughly tested on high-horsepower engines including two making over 800bhp. MLS gaskets offer MUCH greater durability than a composite gasket and can be re-used. They are designed to work with all series (A/B/W) of the SOHC Nissan VG engine. Note: Head and block surface finish of 50ra or better is required for best sealing of MLS head gaskets. |
|||
Head Stud Kit, SOHC VG Engine |
|||
| Now Available! This kit includes high performance ARP studs, washers and nuts to replace the stock head bolts for the Nissan VG30 and VG33 engines. ARP studs are a perfect compliment to our our MLS head gaskets or even stock head gaskets on high-boost VG engines. Kit includes one engine set of 26 studs (13 per head). Made In The USA |

H.P. VG30 Fuel Rails |
||
Next Batch is in stock: top-feed standard finish. Z31Parts fuel rails allow installation of very common 11mm import bosch and lucas style top-feed o-ring fuel injectors. This includes all the EV1 11mm o-ring injectors which are very common on late-model imports and have the same connector as factory on your 300ZX; no connector swapping is generally needed. We use and recommend injectors from 1986-1988 Mazda RX7's for their single cone spray pattern (same as stock injectors, for best atomization and fuel economy) and much higher flow rates. Notes: |
|||
Fuel Injector Seal Kit (In Stock) |
|||
Our injector seal kit is the easiest way to replace your injector seals when using 11mm o-ring injectors and upgrading to our High Performance VG30 Fuel Rails.

Russ' Adjustable Cam Gears - US $249 |
||
THE REFUNDABLE CORE FEE IS $100. EXCLUSIVE part, Now Available For both VG30 and VG33! These cam gears are precision machined stock gears with replacement aluminum hubs. The use of a staggering 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 for the VG30. 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

Oil Pressure Adapter Fitting - US $11 |
|||
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 Plug - US $11 (IN STOCK) |
||
This replacement magnetic oil drain plug will collect small metal particles from your oil and prevent them from being circulated into 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 (OUT OF STOCK) |
|||
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. |
|||
VG Intake Plenum Spacer Kit- US $79 (OUT OF STOCK) |
|||
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. |
|||
170F/77C Low-Temp Thermostat- US $20 (IN STOCK) |
|||
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. |
