Not sure if this is true or not. I have heard several others say that the vtc gear should really be tourqed down while in the unlocked position (notch on gear set slightly clockwise as shown) then locked afterward. This is apparently to reduce strain on the internals of the gear. Just thought this was worth noting
No sir! Timing is the same across the board. Your ignition timing is controlled electronically. I loaded a k20a2 basemap until I get a fine tune, therefore, the 50 degree is set up like a factory k20a2. It never reaches anywhere close to 50 degrees of timing on the basemap, so you're safe!
So, to clarify, the 50 degree gear is safe on K24A2? It's much cheaper than the 45 degree gear. Just gotta make sure the tune is set to factory K20A2 on an RSX ECU? Thanks man.
@@theknytshift6981 so i did everything but its on limp mode and we dont know what it is. Please help. All we did was, 50degree cam gear swap on k24a, rsx oil pump, exedy clutch and 9lb flywheel, motor mounts all around, we loaded up a tsxt basemap tune and still on limp mode, takes quite a while to start, has a z3 starter, stock injectors, rbc any other info u need to know in order to help lmk, thanks in advanced:)
@michaelmiller7937 been driving it for almost a full year now and can confirm it's safe! On a the stock, k20a2 RSX basemap, at that. It'll be tuned soon and I'll be sure to do a video showing results!
@brayancortez3212 I wouldn't know 100% on yours, but my car did not like the TSX tune. For some reason, the stock k20a2 tune is what I had to use to get it run decently. I'd say to double check your parameters in Hondata and see if a step got missed.
I'm so sorry it took me this long to see this. I'm honestly not sure, since I haven't personally done that. On engine swaps, I'd recommend a tuneable ecu unless you're running the engine the ecu ran from factory. I'm using a PRB ecu with Hondata V4 installed.
So you guys think that honda engineers made a big mistake by Installing 25 degree vtc rather than 50 degree vtc .in k24 rbb motor. So now you are correcting it.????
All the 50° does is allow for a wider ignition timing range. If you're going to stay n/a and use an RBC manifold, it's worth it to change. If you're staying stock RBB manifold, it doesn't make much of a difference, but sets the engine up for better tuning capabilities in the future.
I loaded a factory k20a2 rsx basemap due to my ECU being a PRB(RSX). It's the best running basemap for the K series I've found so far. My k24a is running great on it.
Dude, when you pulled out the 15/16, we already knew you haven't done this before and were very drunk, not buzzed! :P

Yeah, you're right. I was backwards. I will say the car is doing fine as it is, but I definitely want update that in future for another video
It’s true, as a dealer technician I confirm it’s true, it should be torqued at 84 ft pound while unlocked.
So you are not running a mechanical 40° stop? I hear that k24 will run into clearance issues past 45°
Awesome! Was struggling with this tonight.
out here doing it with what ya got and some beers! subscribed
🙏🙏🙏
I love your tactics
I have woken up to lots of car and truck mods some guy did when I was drinking.
is there any tuning involved after vtc upgrade?
Much easier to torque something like that by opposing the wrenches by a small amount so that you create a push/pull in the same plane.
Is this good enough or drag cartel gives you more or the same degree or it’s all just hype with the cartel
Love the honesty lmao 🤣 😂
You got this bro
Thanks brother!
So you unlocked the vtc with compressed air, torque it down, and then lock it back? Where do you put the air to do that?
Sorry for the late reply! You have to put the compressed air into the hole on the camshaft behind the gear
Does timing need to be adjusted to the 50 degree cam gear or timing could stay the same, also doing this with oil pump
No sir! Timing is the same across the board. Your ignition timing is controlled electronically. I loaded a k20a2 basemap until I get a fine tune, therefore, the 50 degree is set up like a factory k20a2. It never reaches anywhere close to 50 degrees of timing on the basemap, so you're safe!

My k24a rbb 25 degree cam gear with use stock prb ECU? It’s ok?
Hi just asking which ecu you for k24a
I'm so sorry it took me this long to see this. I'm honestly not sure, since I haven't personally done that. On engine swaps, I'd recommend a tuneable ecu unless you're running the engine the ecu ran from factory.
I'm using a PRB ecu with Hondata V4 installed.
What is the benefits of the 50 degree vtc vs the rbb?
The 50 degree gives you more timing capabilities. Little more adjustment for tuning
@theknytshift6981 so more torque?
In theory, more hp and tq to be had, yes.
So you guys think that honda engineers made a big mistake by Installing 25 degree vtc rather than 50 degree vtc .in k24 rbb motor. So now you are correcting it.????
Basically, yes
@@theknytshift6981 haha ,but how it's possible that I beat 50 degree vtc k24 from my 25 degree vtc. K24.

I'm fixing to do this on my 1989 CRX K24A2. Along with the Type S oil pump and oil cooler. How would you tune this with Hondata?
I've heard 30 deg before vtec and tapering down to 20 deg at the top end.
I loaded a factory k20a2 rsx basemap due to my ECU being a PRB(RSX). It's the best running basemap for the K series I've found so far. My k24a is running great on it.
@@theknytshift6981 That makes since.
Subscribed for more K24 content 😁
Don't look like da block was Turing my boii
Do we need to change the other cam gear or no we can still run k24a one beside that k20a vtc
No, sir. No need to swap the other gear.
@@theknytshift6981 cheers
Are the bolt the same for the 50degree and 25degree?
I apologize for the late reply, but yessir they are
@@theknytshift6981thanks
Do you need to lock the gear after torque to time it?
Yessir, torque the bolt and then lock the gear.
never use an impact on cam sprockets
