Uhhh huh... riiiiiiight.

Pics coming SOON... REAL SOON!!!

Timing sprockets? Hmmm? tell me more about what they would do and would they be cheaper then cams?? would they work with a mild cam? Enquiring minds want to know!

I second the Gen 1 skid plates...for auto trannies too!

Hang on... I'm about to make you regret asking me... ....

Basicly in a nutshell, adjustable cam sprockets allow you to tune the powerband of your engine. By advancing your cams, you will gain better throttle response and more low end torq and horsepower, however, you loose top end. By retarding your cams, you will loose a little bit of bottom end, but you will see significant improvements in high end horsepower and torq. I have here on my computer a dyno simulation software type of deal... its called Dyno2000. Now... I've carefuly maped out my exact engine with the correct 242 duration cams that all US-spec SOHC VG30's come with. With the stock setting (0 degrees), for example, I get a max horsepower of 144 @ 5000 rpm and max torq of 176 ft lbs @ 3500 rpm... prety standard. Now... if I advance the cams slightly to 2 degrees... the whole dyno graph shifts about 500rpm towards idle... but I loose 5 horsepower and gain about 2 ft lbs. If I retard the cams about 5ish degrees (where a stock VG30 really shines with 242 cams), I get 155 horsepower at 5100 rpm and 176 ft lbs at 4000 rpm!!... and the whole RPM rane is broader and stronger.... all just from changing the timing of the cams. With aftermarket cams like the NISMO race cams (262 duration) and things like head porting and polishing (we also perform at L&P Performance) and headers/exhaust... its even more pronounced. The reason the engine responds to cam timing changes like this is because of a little thing called innertia... and subsequently a little thing called volumetric effeciency. The stock cams are set up to provide decent overall powerband and rock steady idle.... thats not what I want... I want ballz to the wallz maximum performance (as Phil will tell you hehehe). By retarding the cams slightly, the engine can make better use of the innertia stored in the moving intake and exhaust gases.... almost literally forcing extra air/fuel into the engine and expelling exhaust gases more effeciently as well as using the exhaust velocity to "draw" more air/fuel into the engine.... in other words... the engine "breathes" better. Infact, you see them all over the place for all kinds of engines... ie, 4-cyl Nissans, the DOHC VG30 found in the 300ZX, Hondas, ect... both SOHC and DOHC alike. Unfortunately until I came along, nobody has ever offered adjustable cam sprockets for the SOCH VG30 found in so many of Nissan's cars and trucks. As you've seen, cams typicly cost in upwords of $350 to $450... I only charge $150 for my sprockets. The overall gain can be nearly identical, but with cam gears, you dont have to dissassemble the entire top end of your engine as you would with cams. Like say, they compliment eachother, if and when a person would like cams too. The reason I first designed the sprockets was for my own use... NOBODY makes them ANYWHRE!! I needed them for my new cylinder heads that I decked 100 thousandths of an inch to get higher compression(.1").... the heads bump the compression from 9.0:1 to roughly 11.0:1 and net me about 15 horsepower. Unfortunately for the cams... it really messes with timing. You see, as the cylinder heads are machined more, the cams get closer to the crank... this causes the cam timing to retard SEVERLY. Therefore, I needed to correct the cam timing somehow, and thus "invented" these sprockets.

Installing them is a breeze... and its super simple to do if you need to get in and change your timing belt at the same time. You more or less just remove the timing belt as normal, and install the cam sprockets in place of the origonal ones via one large bolt on the front of the cam.

Adjusting them is easy too. They are made from the origonal cam sprockets which are more or less welded up with a custom adapter plate. The two resulting peices are held together by 8 grade 8 bolts... to adjust, just loosen the 8 slightly while still on the engine, hold the large cam bolt with a wrench, and while holding the outside of the sproket, rotate the cam to the desired position (sprockets are clearly marked in degrees for easy reference). Repeat for other cam (make it the identical degree setting as the previous one)... and finally re-adjust your distributor with a timing light to the correct base ignition timing. To get at the cam sprockets, all you have to do is remove the top timing cover... and you can adjust them with the timing belt installed and all, no problem. BTW... they are adjustable a total of +/- 20 crank degrees for major re-adjustments as I needed for my high compression cyl heads.

If anyone would like to test a set, I'd let them have a pair of the cam sprockets for cheap. Anyone interested?

I hear ya... I really like the idea too. Phil has a manual '87, and I have an auto '89... so I bet we could come up with something cool. How does 3/8" hot rolled plate steel with grade 8 hardware sound? hehehe

Wasn't George Jetson in the sprocket business?

This does sound very promising tho. This is flywheel Hp, not rear wheel, right?

Yes, correct.

Well, on the whole Z24i engine stuff. I have an '89 w/that engine, that I'm using for parts. I don't need any of the engine parts (my '93 has the KA24E). All I'm taking is the front clip (yeah, a '93, that'll look '89!), front end parts, tranny and X-fer case. Everything must go (rear driveshaft--two piece--, C200 rear 4.375 gears, engine, seats, dash). All I'm keeping is the glass, and what I already mentioned.

Are you saying you have Z24I parts for us? To sell outright, or what? Let us know!! Thanks!

welcome... I want to some the pix of the R50 lifts....

We will have pics as soon as we have the final version installed. They will be up arround May 1st, as a guestimate... at which point we will begin full production. Take a look in the 96 and up section for a lengthy discussion about the lift.

Define cheap. I'm getting ready to do the timing belt anyhow...

I'm ready to do a timing belt too. Let me know if you still need a guinea pig to test them. I'm thinking your price will be more than cheap enough if they're going to be selling for 150. Please email at matthew.roberts1@us.army.mil

He worked for Spacely's Sprockets and thier main compitition was Cozwells Cogs.

Can I vote again? Skid plates (oil Pan if nothing else) for the early, 95 and back, Pathfinders. Man we are desperate!
