Oem valve train components(sr)

[KoukiMonsta]

I was doing some searching about refreshing the valve train. (Redtop sr20det)I figure after so many years and miles these things are bound to wear out. The one thing I can't find replacements for is the springs. Is there a usdm I.e. Fwd application spring that fits?

On a side note can you measure the pressure to decide if they are within spec? Yea lazy not looking at fsm right now...

Please don't tell me to buy aftermarket springs. Cuz codyace will come up in here and smack you! For the purpose of running s3's.

Yes, there is a spring tester. Yes, springs wear out. Would it benefit you to swap them out? Not if you don't know they are bad. Stock springs with the BC's, big no no. If you plan on keeping those cams, I suggest you buy some aftermarket springs. Cody won't tell you to buy new springs if you're running S3's. If you're running anything in the step 2 range that isn't JWT, you need springs.

Currently it's bc everything. But as I (may) have mentioned to you I want to ditch the cams. Thus I don't want to run stock cams on bc springs. Shit I don't want bc anything anymore, as reading/research consistantly points to jwt (at some point s3 but not in the cards $$$ wise. I have stock cams though) Which leads me to needing to find some springs to install. As I found you can get the retainers.

My note about them wearing out is in regards to that fact that I saw used ones on eBay.

Ps anybody wanna buy a full bc valve train assembly lol

Their springs are actually the heaviest out of all the single springs out there, but if you're swapping back to factory cams, you don't need them.

I would be more concerned with removing the cams at this point. If you want to drive the car and put some miles on it, throw the factory cams back in. You aren't going to hurt anything by running them. Stiffer springs made lead to slightly more wear over time, but it's not going to effect anything you plan on changing down the road.

As I stated though, you can get a spring gauge. I'm not sure what the factory spec is suppose to be, but perhaps it's in the FSM.

[KoukiMonsta]

Fair enough. As you said primary concern is to remove the cams. Especially since at my power levels they are probably hurting torque vs helping to gain any power.

When you talk about wear does this refer to all components? Am I wearing out the bearing surfaces of the head prematurely? Or more along the lines of cam and rockers? I've read time and time again of the s3 and oem valve train making all the power that I want (400 area with supporting mods) so lets not wreck anything before I get a chance to do that.

Cam lobes and rocker pads, will see the most. Now I'm not saying over night they'll wear, but yes, over time(tens of thousands of miles) they will. Let's say you get 200k out of factory parts, perhaps you'll add 20% faster wear, which means you'll only get 160k out of these. I do not know specific wear rates, just using it as an example.

Unfortunately when you upgrade parts there is a trade of. I wouldn't sweat it too much man. Do what you can now, upgrade later. I think miles on the motor and sorting out your low vac issues are priority.

[KoukiMonsta]

Yea that's the priority for sure. I'm just sorta brainstorming if you will about future plans. The more I learn the more I see some poor choices I've made parts wise in the past. And the goal is to remedy them.

If anyone does know about the springs I'm still curious feel free to post up.

I'll get back to you once I figure out more, thanks as always.
