Group Buy for adjustable intake cam gears for non VVTI 1UZFE

[ivan129]

Hi everyone...
Is there enough interest for a group buy of Adjustable Intake cam gears for non VVTI 1UZFE's. The suppliers in China wants a minium order of 40 sets. I'm not sure on the final price until they come back with a quote but judging by the prices of their other sets, could be 60 - 80$ a pair + shipping.
I do not wish to manage this, just purchase 1 set for my use.

Platinum Racing now produce adjustable cam gears for early 1UZ non VVTI engines. Be aware that the Left cam gear has been assembled incorrectly.

Can you elaborate on that? I have a set of the PRP adjustable cam gears and it looks as though they are not assembled correctly and couldn't use them. I haven't been able to get any info out of them about it. I just e-mailed them again.

I'll bet then you must be their 2nd customer to have purchased these. PRP have now released an update they label as V2 after I told them about the problem. I'm guessing you haven't installed them yet either as you would have picked the problem. You will need to do a comparison between the OEM gear and the PRP ones. You will find that the right hand gear is fine, whereas the left hand gear has the trigger tab for the cam angle sensor 90 degrees retarded. Easy fix you might say just remove the screws rotate the trigger ring and refit. Well the problem with that is that only 2 screws line up, the other 2 don't. The fix is that PRP have now drilled new outer gear to fix the problem. Next issue is that you can't fit the cam sensor mounts back to the engine because they fowl on the gears. Picture below shows you what I machined off.

Another thing I can add.. Their version 1 left gear could work (be used) as is, if you added 180 degrees to the ignition off set, however ths is something I didn't want to do. I wanted the trigger tab to be facing in the right position. You will need to check the ignition offset anyway once the engine is running. The way I used to dial in UZ cams using OEM gear, I would drill the dowel slot to allow adjustment and always found the offset needed to be tweaked a degree or 2 afterwards. The above mod must be done if using PRP gears. It would appear that PRP never test fitted their gears as they don't appear to have any answers. Don't think I would purchase another set of these though. Modding the OEM gears works fine. There are a number of other tricks you will learn when attempting to dial in UZ cams. Unfortunately none of the supposidly reputable youtube builder have any clue about doing this.

I may very well have been their 2nd customer. After reaching out to them, they are sending me a V2 left gear. However, apparently I will still have issues with the cam sensor mounts? I'll keep that in mind if I/when I try to install them again.

PRP adjustable gears for the 1UZ seem to be the only product on the market that I've been able to find. And its great for them to bring the product to the market, however they couldn't have test fitted their gears or actually tried to dial in a set of cams on a 1UZ. My comments are based on the following issues. 1) the left hand cam gear sensor ring was fitted in the wrong position but the cam belt timing was correct. If you simply rotated the cam sensor ring 90 degrees, redrill and tap the 2 x M3 screw mounts to fix the problem, the cam belt timing mark works be 90 too far adavanced. So when they fixed this on version 2 they had to grind in a new timing mark.
2) you can not fit the standard cam sensor brackets with thes gears fitted unless you modify the cam sensor brackets. 3) the plastic adjusting tool they brag about in their video used to insert a 1/2" wrench to rotate the gear is crap and breaks. It might be ok if stock springs are fitted however most guys indexing cams will be using heavier valve springs. You're better off using a 24mm spanner on the camshafts. Then there's the fun of indexing the cams. You will need to compensate for cam belt stretch otherwise your cam indexing will be a waist of time.
