How To Delete S14 VCT?

[Cubantunr]

Ok looked around and all i got was a bunch of mixed articles. I'm wanting to disable VCT on a S14 sr20det blacktop. Some say simply unplugging the solenoid will keep it from working, others state you have to change the cam gear and shaft to s13s. Does anyone have actual EXPERIENCE with deleting it?

Reason is because i don't want to experience rattle and because i simply don't want it. I know ill lose some power but thats ok. I plan to run all upgraded parts. cams, gears, valves, etc. are s13 and s14 sr20dets heads the same internal? Aside from VCT.

Once again thanks and don't post if you have not done it. Already too many different theories.

Can I get a bump?

You need to install an S13 cam gear. You can disconnect the solenoid plug as well to keep the solenoid from opening.

With that said, I strongly suggest you keep it. It is not just "a little bit" of low end power, but quite a bit. Not only that, it helps partially with turbo spool.

I'm planning on upgrading to brian crower stage 2 cams and valve train so it'll have to go.

If I were you, I'd return those cams or refrain from purchasing them. BC cams are known to have issues, specifically centerlines being way out to the point of needing cam gears to adjust or dial them in to the correct spot.

Find some Tomei, HKS, or JWT S3 cams, you'll be better off from the start. Tomei and HKS make VTC compatible cams however, HKS cams will be a bit more pricey and harder to locate.

I'm talking about bc camshafts? I've never had an issue on my other sr. I run jwt cam gears.

if you get rid of the VTC I'll need your VTC gear.

but to answer your question. unplug solenoid, swap intake cam gears and goodbye VTC.

Doesn't the rattle bother you guys?

So am I, BC cams suck. There are much better choices available.

A new VTC cam gear will fix the rattle issue for a good period of time. Most likely, it'll outlast your setup or bottomend.

what rattle?

[eek]

A new VTC Gear that will fix the rattle. If you are going to eliminate VTC mite as well sell the s14/s15 motor you have and make some money and use a s13 sr20 motor instead.

[Cubantunr]

Yea but the rattle will eventually come back and I don't want to dish out a couple hundred over n over besides they say with high hp applications the vtc does hardly any good

If you get a new VCT sprocket, wouldn't it last a long time before it rattles?
Some people never even go to that stage.

My SR has well over 50k miles (about 40 drifting event) and never went out. I am sure it's coming soon though..

I eliminated my vvt by disconnecting selenoid, using stock s13 cams and gears, and s13 ecu&maf...on 13psi it made 268rwhp on a Mustang dyno with no other mods. I didn't dyno it before but it actually felt like it had more power.



Also I'd like to add...virtually no turbo lag with the stock t28.

Also had some bc 272s in my evo...just make sure they're in spec. Picked up almost 80whp off of those babies.

I run vtc with brian crower cam, solid lifters etc... not a single issue yet and the results are awesome.

the vtc when tuned properly let me gained something close to 80lb/ft of torque at the wheels on the spot in the powerband..

i also ran with a Noisy vtc gear for a few years with no problem

I've had a set of BC cams for about 8 years on an S13 sr20det. they do the job very well to say the least. Installed straight up, they give every indication of doing what camshaft upgrades are intended to do, that is, holding VE high and flat where it counts.

On a daily driver, I would still recommend stock springs and JWT S3 camshafts. every.single.time. set the rev limiter to 6400rpm and have fun. for years.

I've dealt with the VCT gear rattle, its annoying at first, but you eventually just tune it out. I've been running a new VCT gear for 4 years no issues yet.

[Rb26kouki]

can they be repaired or rebuilt ?

[jr_ss]

There is speculation in that and I believe there was someone that tried, however I do not know the out come of this.

IMHO, if you're going to go through the trouble of "rebuilding it", which requires removing it, I'd just throw a new one in and not worry about it for 50k miles.

Is the S15 VCT gear the updated version that doesn't rattle?
