GROUP BUY! Cam gears with 3deg retard for V6 1GR. | Tacoma World

I had never heard of this until I stumbled across it on TW. Read through the posts (it's long but a lot of good info and testimonials) and if interested post over there. I am in no way affiliated, just want a set. If this breaks any rules, I'm sorry in advance.

Really surprised more V6 owners are not participating, from what I read on the link it really seems to bring the engine alive. Oh well!

It's a popular mod on Taco's apparently. I'm surprised there's zero interest. Oh well.

I read through some of the Tacoma World posts too and it looks like a really good modification! I'm a tad scared to tear into the engine on my daily driver, otherwise I think I'd be in. Seems like it offers a decent benefit and I think it would be a good experience to get inside the overhead to look and learn firsthand. I'm not familiar with engine part pricing, but $120 for a custom machined part in small quantity that adds decent performance seems like a good price too.

With all the successful installations I'm sure its a non issue, but I thought I read the front chain cover is bolted onto the oil pan and this lead to the Toyota recommendation for engine removed during HG replacement? The main issue was something about not being able to properly torque front cover without fully loosening the oil pan, but not sure since I haven't dug deeper into that.

Only the valve covers come off for this install, not the timing chain cover. You don't mess with the timing at all, if you follow the steps.

Where do i sign up? TW?
Guess i better toss these in the box of 'to do' sitting in the garage.

These neat little mods seem so hit and miss... due to limited intrest, not around long i mean.:hungry:

I went back and looked at the video and I might be an idiot :ybrick:. I now see that both the timing cover is still on, and the timing chain doesn't even wrap on the exhaust cam. For some reason while typing, I was thinking that the timing chain went over both intake and exhaust camst, but I now see/remember that mini chain links intake to exhaust.

Maybe I'll have to conquer my fear of opening the engine up and grab one if they do another round. Definitely let us know how the install goes and any butt dyno results!

As far as mpg I can't say yet I've only driven it once or twice down the road.

As far as power, it does feel to come on earlier in the lower gears. The exhaust note changed and it hunts less for gears going up inclines. At least to me, it was worth the money.

Right away I noticed it idles smoother/quieter. The RPM's are lower at 75 mph than before. Is it a back to stock tire size difference? No. But it does feel more powerful/alive if that makes sense.

Going towards my house is a steepish incline with a 65 mph speed limit. Before this the truck would kick in to overdrive but it would hunt. As in OD then drop it then kick into OD again with no input from me. Now it doesn't kick into OD on that same stretch unless I'm really on it.

I have 33's, plate front bumper, steel skids, sliders, hitch tire carrier with full size spare. She's a heavy girl lol. I had been logging my MPG for some time manually because I knew I was gonna do this mod. It averaged 14.7 over the last 6 tanks according to mileage/gallons.

I haven't gassed it up since the cam gears, it's been just sitting mostly. Once I get through at least 3 or 4 tanks I'll report back.

The install was wicked easy, though I did have an extra set of hands. The process is time consuming as there is lots of clips and connections on the intake manifold. Go easy on the install on the valve cover bolts and do it with a manual tool. I snapped one of the first ones off (damn milwaukee 3/8 ratchet) . I'll have to address that in the future but for now it's not leaking at least. The Mercedes engine mount tool they talk about in that thread made torquing the cam gear bolts super easy, glad I had it.

I do recommend buying new gaskets for the job. I got both valve cover gaskets, plenum gasket, throttle body gasket, PCV valve and FIPG for around $80 from McGeorge Toyota online. At 155k mine felt a little stiff compared to the new ones but not brittle yet. Also did the spark plugs while I had the intake manifold off and everything apart. I was pleasantly surprised with how clean everything was under the covers. I did notice a bit of oil in the plenum under the intake. None on the oil plugs. I may install a catch can just for peace of mind.

Sorry for the rambling post, just things that came to mind once I started typing. Feel free to ask any other questions.

Something like 36 pages on TW since july 7th (last year, was thinking last month...doh)... all good.
Guy said he has sold over 300+ of these.

Mine is in the mail!... now on the work table...

On a 3rd round of group buy now.

Thanks for the detailed info, I already ordered a custom Y pipe from a local shop. Hopefully there will be another group buy in the works soon.
