adjustable cam gear for the 5sfe, anyone interested? Options

[presure2]

hey guys.

im working on having an adjustable cam gear made for the 5sfe, figured i'd throw it out there, see if anyone else is interested.

basicly, it will be a modifyed 5sfe cam gear, much like the ATS racing adjustable cam gears for the 3s.
heres a pic of the 3s gears.


aaron from ATS has agreed to make me a gear, for 110$.
im thinking if we can get 5 or more, we may be able to get a bit of a price break, but i cant garantee it.
i am 100% guessing here, but im thinking a 5-10whp gain from it.

lets discuss!

IN IN IN!

count me in....Will this help or hurt a turbo set up?

[DeW_H0e_GT]

in!!!!

[presure2]

glad to see there is some interest in this.
we will need to source some extra cam gears for this.
i will be taking a ride up to the local junkyard to pull a 5th gen gear, to see if they are the same.
if that is the case, extra gears will be as easy as taking a hammer 17mm wrench and a pair of snips to the junkyard.
the adjustable gear should be even more beneficial to a turbo application, with bigger gains up top.

So what kind of real life improvements will a regular GT or ST have?
And how hard is it to change the gears?

this is not being made for the ST.
im guessing a 5-10whp gain.
the install is basicly part of a timing belt job, since the timing belt has to come off to get to it.

ill buy too from u

What are the advantages in this over adjusting the timing? I don't have the cash to buy one from you, but I will attempt to make my own, and I garintee that. I'll make it even if there isn't much a difference. By the way, which direction is it that I turn the distibuter to advance time, clock or counter clock? Great job on the inovations btw.

turning the distributor to the right (towards the back of the car) will advance the timing

dont do it without a timing light.

well gee, thanks.
for the rest of you guys,
we have confirmed that the 5th gen and 6th gen cam gears are the same.
that makes getting a spare gear very easy.

I've already messed with the timing some. I thought it was clockwise that I needed to turn it, but it's nice to be sure. I still don't understand what could be gained out of a cam adjustment of a twist in the distributer.

[presure2]

because adjusting cam timing is diffrent than just turning the distributor.
google cam gear. there is plenty of info out there.

I can look else ware easily, but I thought it might help your selling them if you explained what exactly it is that they do. And this is in the engine/transmission/maintenance forum, and I'm asking an engine related questions. I don't know if you were really trying to be rude with that. I kind of took it that way. If I was new and seen that, it would have driven me off. This is supposed to be a place where we share info.

naa, not trying to be rude...there is much more detailed info than what i can give you if you search google...im still learning just like you guys every day.
i know your not a noob, so i assumed youd understand what i meant.

I think you are mistaking ignition timing with cam timing here? Is it possible?

[Hanyo]

Cam gear timing affects the way the exhaust and intake valves open and close. Ignition timing has nothing to do with this. Adjusting your distributor will not affect cam timing.

What adjustable cam gears do, are they allow you to delay or advance the opening or closing of the intake/exhaust valves. What they do allow you to do is delay the exhaust valves from closing to allow more engine scavanging. They will not affect how long the valves stay open.

First generation toyota VVt ( NOT VVTI-L) utilized cam advancements to increase performance of the N/a engines.

Cam adjustment alter the stock cam timing to get the most from modifications like upgraded camshafts, headwork, or alterations to compression ratios.

[Bigmeanbulldog55]

With the exhaust being a slave cam, would I be able to adjust the single intake cam to maximize scavenging? I didn't really understand the reasoning behind ajusting the slave cam thing. If they were apart, you could delay the exhaust from closing. So distributer would adjust my spark and the cams adjust my fuel. Sounds like I would need at least a timing light if not a dyno run or 2 to maximize performance out of these things. I don't know how to go about it free hand, except for timing. Just adjust upward a small bit at a time.
