Anyone knows of any adjustable cam gear sprocket for the S38B38?
I found this one, from VAC Motorsport in the US.... quite expensive.... I searcher the forum but just found some information about the Dinan ones (not adjustable) and the OEM ones as well...

I have had this idea already too my friend, thanks for your comment.... it would really be much much cheaper, BUT I do not have anyone here in Brazil that I can trust to do this job correctly, without compromising the sprockets.... I have already spent so much money in the car with the engine rebuild, head work, standalone, shorter diff, etc etc, that I do not think that now would be the time to try to save some money like this... maybe finding some other supplier, but not trying to do it by myself....

Hi,
That should not be a problem for most of machine shops who offer engine service such as head work, valve job etc...
Depending on the price and process of making it, it would BE perfect David!
Anri, to males it is really easy... To make it properly not as much... I cannot put it on a simple press to have it fixes and work on it... It is necesary to first build a fixation toll to hold it by the center not to damage it...
Sorry for my poor technical english...
Another question for you gurus... Will the S14 Evo ones fit the S38B38? I am talking about 11311311781 part number... And I also found the 11311308513 part number as well...
I have doubts because I know S14 and S38B36 can interchange it, but the camshaft sensor on B38 is on a different position...

Hi,
In your particular case with aftermarket performance camshaft to fit S14 EVO A100 does not make absolute no sense ! You need adjustable so you can do fine tuning.
You need to be careful who is doing your camshaft degree because if you dont trust machine shop to slot your cam gears job for students! I am scared to think of who is going to degree your camshaft...
The S14 EVO A100 was discovered back in early 89-90 (i dont want to even go in details by whom because its not proven etc..) to be used in S38-B35, used only on the exhaust site.
Their are 2 choices either retard or advance by half a notch. If advance the exhaust you are increasing the mid range. If retard you are shifting it to upper power band. Recently I changed head gasket on M88/3 and advanced the exhaust cam gear by half a notch(slot the cam gear). On my daily driver I have that Retard for the upper rpm band.
The B38 A108 E108 was upgrade used in S38-B36 by advancing the Intake by 2 degree and retarding the exhaust by 2 degree being from stock B36 A110 E110. Great upgrade with TMS chip and open free flow exhaust.
Hope this will explain the A100 EVO S14 why is not a choice for you.

Hi..
Iīm the engine builder of Passosīs engine.
From what you say here, is very easy to see that you never saw in your life a EVO sprocket.
The option to choose that is not due the OEM timming fixed, but itīs already sloted, just fixed OEM timming by a removable woodruf key.
Our doubtīs is not due timming, but fitment (example: pick up rotor for cam sensor that is used in B38, but in B36 and S14 is distributor rotor) .
By the way, i believe you never used it before (considering your words that you said here), so, cannot help us.
Regarding the machine shop, i donīt know in your country, but machining cylinder head and cylinders, is very different job than do custom milling cutter in a sprocket. Even if they are technical capable to do that, the focus of a Engine Machine Shop is not that.
When Passos said about reliability, he refer about the precision of machining. Anybody can machine anything, the precision of the job is the difference. So, to stop a big Machine shop (that have production line and need to stop everything to machine two sprockets) that can have the precision that we look at, will cost about the same to buy new sprockets.

This comment definitely put a smile on my face...

I think the way you are trying to find your need is very poorly wrote/asked without technical details etc....What you are saying above the words you have used does not make any sense
Indeed 'Pspassos' does not make his hands dirty as for example I, Raymond, Tomba, Wout, David, Darren and other board member..He, pspassos is using you Mr. Engine Builder in one word pspassos does not have the ability to build the engine.
I tried to give some general input to "Pspassos" about factory cam gears to 'Hop Up' and do mild upgrade. It has nothing to do with your particular engine build etc

Another very naive comment...In this country were the automotive industry, engine building is very advanced and people who own very big shops with very advanced machinery can do it. I am speaking from experience. Because I have done it many times. And if you having trouble to do so its all your problem.

As I always like to say "Quality Has its price" choice is yours. If something does not make sense for your $ do not buy it. No one is pushing you to do so.
Mr. Engine Builder. with your very poor technical description/question it made barely sense in my opinion...
I am willing to give my opinion wether its valuable to you or not. You should appreciate our board members the effort to help because you are the one who needs help not me/us the members, indeed you don't.
Today I made the effort to take some pics in order to help you Mr Engine Builder and Pspassos some one who is telling me that I have never seen a100 cam gear in my life, i like that..
Hear is S14 engine that I have completed not long ago I wont go in details and specification etc...
As you can see its has Individual coils for each cyl as S38-B38
Do you see some were the camshaft position sensor ?
Yes I will install adjustable cam gears very soon.
