Brian Crower CAMSHAFTS For Toyota 2JZ-GE 2JZ-GTE Non-VVTi

2JZ-GTE Non-VVTI CAMSHAFTS

The engine of choice for the fastest of the Sport Compact drag cars due to the tremendous power potential of Toyota's 2JZ-GTE, factory twin turbo engine. It is also used in Drifting with it's rear wheel drive setup. The 3.0-liter, inline six cylinder has proven itself to not only be capable of tremendous power output, but to also be extremely reliable. Made from 1994-1998, the 2JZGTE was employed in the Supra Mk IV chassis. The name is a combination of Celica and the word Supra. "Celica" is derived from Latin and its literal translation is "celestial" or "from the heavens". "Supra" is a word that is derived from latin that stands for "over, above, beyond, or greater than". So a translation to english would be something like "from above the heavens" for the entire term.

2JZ-GE NON VVT-I CAMSHAFTS

These camshafts feature the distributor drive gear on the exhaust camshaft and are different than the VVTi option that was added in 1997 for the 1998 model year. The Toyota 2JZGE non VVTi was released in 1991 in the Toyota Aristo (JZA80). The 2JZ is an inline, six cylinder layout, belt-driven dual overhead camshaft with an aluminum cylinder head, 4 valves per cylinder and a cast iron block. The engine block, crankshaft and connecting rods of the 2JZGE and 2JZGTE are the same. The 2JZGE engine platform was utilized in the Toyota Aristo/Lexus GS300, Altezza AS300/Lexus IS300, Chaser, Cresta, Crown, Soarer/Lexus SC300, Supra and Mark II Toyota chassis configurations.

CAMSHAFT BREAK-IN

Brian Crower, Inc does not recommend using synthetic oil during camshaft break-in. If you must run synthetics during operation, even though we recommend that you do not, make sure the synthetic contains a high zinc content (ZDDP count of 1400 or more). Follow OEM cam cap torque sequence and specifications. Use a liberal amount of aftermarket engine assembly lube, again with the recommended amount of zinc content, during installation and assembly. Check cam follower or bucket surfaces for any abnormal wear and/or scuffing. On initial start-up and break-in run engine at 1500-2500 rpm for 20 minutes.
 
RECOMMENDED MOTOR OILS

Brian Crower, Inc does not recommend using any synthetic motor oil lacking zinc (ZDDP). This is especially critical with flat tappet, bucket or scrubber type finger follower camshafts (2JZ, EJ Series, B Series, SR20, etc…). Roller followers are not as critical but it is still recommended to utilize the added zinc content to prevent any premature wear.

To protect a new flat tappet, bucket or scrubber type finger follower camshaft during camshaft break-in:

Use a dedicated break-in oil that’s specifically designed for flat-tappet camshaft break-in.
Use mineral-based engine oil (preferably a nondetergent oil in the 30W or 10W30 range), plus a 16- to 20-oz. bottle of specialty ZDDP additive.

To provide long-term protection for a flat tappet, bucket or scrubber type finger follower:Use a specialty engine oil that contains high levels of ZDDP (around 1000 to 1200 ppm). Brands like JGR Driven, Shell Rotella and Chevron Delo and Brad Penn are excellent brands to source.
Use the engine oil of your choice, plus a bottle of ZDDP additive with every oil change.

Note: Engine oils specifically designed for use in diesel applications will usually feature more zinc than passenger car gas engine oils. However, diesel engines are coming under greater scrutiny as well, in an effort to further reduce nationwide emissions. So, while a dedicated diesel oil may be better than a passenger car gas engine oil in terms of zinc content, you can’t automatically assume that any diesel oil contains enough ZDDP to protect a new flat-tappet cam.
 
ADJUSTABLE CAM GEAR SETTINGS

Unfortunately there is no universal or magic cam gear setting that works for all applications. Tuning via adjustable cam gears comes down to driver preference with regards to idle quality, desired operating rpm range, piston to valve and valve to valve limitations as well as other considerations like power adders and stand-alone ECU capabilities. For general discussions, widening the lobe center (LC) will yield more top end performance and smooth idle characteristics. Tightening the LC will typically result in a rougher idle and deliver more bottom end torque. Gear adjustments on 2JZ, SR20, EJ Series, B Series and 4G63/Evo are as follows:

Widen Lobe Center: Retard Intake / Advance Exhaust
Tighten Lobe Center: Advance Intake / Retard Exhaust

Note: It is highly recommend going a maximum of 2 marks in any direction at a time on one side (intake or exhaust) for adjustment. Any more or adjusting both intake and exhaust at the same time, may result is extensive engine damage.

Cam bolt (not cam cap) torque specs for each application are as follows:

Honda B Series – 22ft lbs (less than OEM spec)
Nissan SR20 – 101 to 116 ft lbs
Mitsubishi 4G63/Evo – 58 to 72 ft lbs
Toyota 2JZ – 57 to 62 ft lbs
Subaru EJ – 70 to 75 ft lbs
 
BC CONNECTING ROD TORQUE SPECS/INSTRUCTIONS

For proper rod bolt installation on Brian Crower connecting rods, please follow these important steps. Rod bolt threads and underside of bolt head should be lubricated thoroughly with supplied BC/ARP lube. Cap should be seated on rod by aligning cap by hand and tapping in place using a rubber mallet. Alternate tightening of bolt to avoid cocking the cap. Torque the fastener to achieve bolt stretch using the torque range below. Use a quality rod bolt stretch gauge, as improper bolt stretch will cause premature failure. If using a torque wrench sequence, torque initially to 10 ft lbs, then use one consistent pull to achieve the proper torque specification listed below:

5/16” ARP2000 Bolt Stretch = .0050” to .0055” / Torque Spec – 25-28 ft lbs
3/8” ARP2000 Bolt Stretch = .0055” to .0060” / Torque Spec – 45-50 ft lbs
3/8” ARP625+ Bolt Stretch = .0063” to .0067” / Torque Spec – 50-55 ft lbs
7/16” ARP2000 Bolt Stretch = .0055” to .0060” / Torque Spec – 65-70 ft lbs

Torque used during manufacturing: 26 ft lbs – 5/16”, 45 ft lbs – 3/8” and 70 ft lbs – 7/16”

To accurately determine the life of a fastener, it is recommended to log the fastener’s original untorqued free length and compare to free length after teardowns. If the free length increases by more than .001”, or there is any deformation or galling, the bolts must be replaced or failure could result. Fasteners are susceptible to corrosion so caution must be used when handling with bare hands or left out in the open to prevent exposure.
 
REPLACEMENT PARTS

If not a warranty issue, replacement parts (valves, springs, retainers) are available for individual purchase in the online store https://store.briancrower.com

If needing a replacement connecting rod, please contact BC with the gram weight of the existing rods so a replacement rod can be weight matched and we can advise on availability. If a replacement camshaft is necessary, please contact BC with the correct cam part number and whether it’s the intake or exhaust side (driver or passenger side also required if Subaru). We offer special pricing for replacement parts, so please contact Brian Crower directly for better service on one off’s. If a warranty issue, please refer to the Warranty section in this FAQ for details.
 
CAMSHAFT DOWEL PIN FAILURE

The dowel pin does not drive the cam gear, it is merely a locator for proper camshaft installation. If the dowel pin breaks on a camshaft, it is typically the result of a loose cam gear, a timing belt issue or some other cause not related to the dowel pin. BC offers replacement dowel pins but under no circumstances is a broken dowel pin a camshaft warranty issue.
 
GETTING LOBE SEPERATION

Based off BC0211 - Cam Timing Tag

Add the total duration of intake and exhaust (ex: 218 + 218 = 436)
Divide this number by 4 (ex: 436 ÷ 4 = 109)
Add the intake opening and exhaust closing numbers (12 + 9 = 21)
Divide this number by 2 (ex: 21 ÷ 2 = 10.5)
Add this number from the number on line 2 (ex: 10.5 + 109 = 119.5 LC)
 
VALVE JOBS & VALVE TRAIN GEOMETRY

If replacing your valves, especially if going with larger than stock head diameter, please verify the installed height if you are having issues with setting recommended valve lash or are seeing abnormal wear on rocker pads or buckets. If the valve is seated too short it would cause the lash to be tighter or, on rockers, to wear to the outside of the contact surface. If seated too deep, lash would be looser or, again on rockers, the wear would be on the inside of the contact surface. This will also impact rocker ratio figures in finger follower type applications. A handy way to check geometry is to put dykem on the wear pads or bucket and spin the cam over by hand and the wear pattern should be in the center. The wear pattern should never leave the contact surface or it will cause rocker/bucket and/or camshaft failure.

To measure valve installed height, use a pair of calipers or 6 inch scale and measure from the bottom of the spring seat to the top of the keeper groove. You can seat the retainer and keepers on the valve (no spring) to get an accurate reading. It is critical that you maintain OEM/stock installed height or severe damage could occur. All valve spring specs are based off of the factory installed height, including whether the valve spring can accommodate maximum camshaft lift.
 
STROKER KIT DISPLACEMENT

The formula for CID (cubic inch displacement) or Total Liters is:

BORE x BORE x STROKE x .7854 x No of Cyl (4, 6 or 8).

All stroker pistons are custom. You determine the bore size when ordering the kit.
