CNC Machined 1GR-FE Exhaust Cam Gears (3° Retard)

You must save that on your phone like I do

My problem is finding someone with them in stock

 

Man that's a bummer. My drivers side chain tensioner was sitting up a little higher than the passenger side but still had some cushion to it. You can see the difference in the pics I posted

 

Yeah I looked at yours hard trying to figure out if I was making something out of nothing. In the end, it’s not perfect so I won’t go back together with it until I can make it that way, gonna go ahead and replace both sides. The earliest my local parts house can get them is Tuesday so I’m hoping San Marcos Toyota has a set and I can get them tomorrow. If not my truck will have to sit until I get back from work in a week and a half.

 

No stocking dealers in all of TX.

 

Wait. Passenger side Should be tensioning down right? On the slack side of the chain. You're saying that you've got no upward pressure on that side. Driver side tensions upwards.

 

No downward pressure on passenger side. That and the top pad broke so now it slides over into the rear of the intake gear.

 

Welcome to my personal hell. I can’t even get dormans by tomorrow.

 

Can we safely say that installing the cam gears doesn't REQUIRE a re-tune? Would like to set up a buy/sell thread for this.

 

I’d say that it’d be fine without a re-tune. But, to take full advantage of the change, tuning needs to happen.

 

I totally agree that it would be fine without the retune just wouldn't maximize gains, My thinking is if it were to be sold to someone without tuning capabilites would it potentially kick on a check engine light etc?

 

Judging on what little I drove I would agree. I didn’t change my tune and everything looked great.

 

For those installed, does it run better? Mpg’s aren’t that big of a deal to me.

 

Without a doubt.

 

In what way? Peaky?

 

I don’t have a lot of seat time but I would say biggest improvement would be 2800ish up, with no loss down low.

 

@JuanitoBunito, you haven’t hung out here either. Craziness continues.

 

So I’m trying to understand all of this from an OHV standpoint. We’re increasing overlap, but is that also altering what I want to call lobe separation angle? I know that’s an OHV term. Clearly it seems to work.

 

Diamond, How many miles are on your truck? I'm contemplating doing my timing chain and tensioners while I'm in there. I'm at 140k miles

 

These would be super cool and I’m sure I could benefit from them.....only problem is this is way to in depth for me in terms off digging into my engine.
