not 100% on this but i think loxy is running these cams with stock valve springs. so if they run with stock, surely you could keep your toda springs. they work with more aggressive cams like the toda's so you'd think theyre'd work with the skunks. how come your changing from toda to skunk2 cams anyway?

Loxy is running stage 1's and I think it would be advisable to change the springs with these cams :)

Not sure about compatability with the toda springs tho sorry! Also check and see if you need pocketed pistons with these cams as you do with the stage 3's!

Sorry mate didn't mean that to sound like I was "dissing" what you were saying! Lol

And sorry if I sound like a d-1-ck again but I wouldn't recommend the skunk2 springs, skunk2 don't actually make them, they outsource them to a Chinese company (for cost) but. Have no idea why as the quality is very poor and they tend to fail and ruin engines! :(

Lol ;)

Doubt they'd tell the truth tho! Lol I've seen a couple of wrecked engines from their valves, just speaking from what I've seen, perhaps they have stopped outsourcing them now tho :)

People think you can just chuck in a set of aftermarket valve springs with any cam profile you like and it will be all grand... not the case i'm afraid.

The poundage of the spring has to be correctly matched to the harmonics of the cam profile (at all feasable RPM's) and be able to cope with the net lift applied to it.

For best results, only use the valve springs specced by the camshaft vendor, do not mix'n'match.

Tqvm all the replied...

Brother civi08, to answer your question, I bought 2nd hand damage TODA Spec-C cams and brand new in box TODA valve springs. All the mods listed in my signature yet to be install. 1st step i thought the cams can be repair but can't anymore:-(. As you know, brand new toda cams much more pricey effected Yen currency increase right now. and with my tight budget, that's why I planned to buy just skunk2 cams...its about half price toda.

So guys, about the toda springs, from the TODA website they said their uprated valve springs can be use up to 13mm lift. Is it means 13mm already max lift for their springs? For info, all toda K-series cams from A2 till highest spec (Spec-F) just have 13mm lift max while this skunk stage 2 has 13.5mm lift of intake cam. I got worried right now thinking of it:-(. I just really hope nothing goes wrong with 0.5 extra diff...haihhh.:confused:

Yes correct, if you already own the skunk2 stg2 cams. I would recommend the Supertech SPR-H1020D valve springs.

They have high seat pressure to cope with the aggressive ramp rates of those cams (100lbs) and allow lift to 14.5mm (giving you a safe margin of 1mm before coil bind).

EDIT: Just noticed you just own the toda springs right now, can you find the specification of the springs on their packaging??

Aye, Skunk2 stage 1 cams with Pro Series Springs. They are dual springs so needed the seat set as well.

Stock retainers though as they don't crack. Will check for wear every 25k on the clearance checks. Should be OK on stage 1s though.


And sorry if I sound like a d-1-ck again but I wouldn't recommend the skunk2 springs, skunk2 don't actually make them, they outsource them to a Chinese company (for cost) but. Have no idea why as the quality is very poor and they tend to fail and ruin engines! :(
There are a lot of horror stories about Skunk2, all their bits if I'm honest. Majority of the time they are good. Otherwise Skunk2 wouldn't sell anything, and if what you are saying they wouldn't sell any springs as every tuner would know not to fit them again.

I think it boils down to a few people being very unlucky, but you are always going to get people posting up about failures, and how many thousand people would have fitted them but don't post up so to speak.

I use skunk2 parts too John and I have never had any issues with their parts, indeed I find that the quality is good, its just that the springs (at least used to be) outsourced so the quality wasn't as good, if however it is skunk2 that are making them now I have no doubts that they will be good

Aye no worries!

Their blurb from the link posted earlier on the pro series sounds encouraging though.

Skunk2 Pro-Series valve springs are simply the best valve springs in the sport compact market. Pro-Series valve springs are designed to handle the demands of extreme lift camshafts running at the prolonged high rpms of professional championship level racing. We have tested the Pro-Series valves springs up to 11,000 rpm. The Japanese milled super clean chrome silicone wire is 100% eddy-current inspected before coiling. After the spring is coiled, it is heat treated, shot-peened, and further enhanced with an advanced proprietary chemical polishing and nitriding process. The end result is a lightweight valve spring that will safely accommodate high lifts and has superior resistance to load loss even under extreme operating conditions. This type of performance is only possible because of the additional processing and stress relieving that goes into Pro-Series valve springs allowing us to use less coils. The Skunk2 Pro-Series valve spring is the only valve spring designed for use with Skunk2 Pro-Series camshafts.

Every company has horror stories, but courtesy of the internet the horror stories are easier spread than the happy ones.

Saying that even my fuel rail didn't fit straight on and needed " tweaked and persuaded ;)"

Brother pulpmelon, there is no details technical spec of the spring inside the box. Here I attach some image of Toda springs.

Brother Loxy, is it true I need to buy skunk valve seat also to use with their dual valve spring? I thought our oem valve spring already dual springs so it can be use with skunk spring with no issue:confused:

Interesting, are these toda springs 'single' springs with no smaller spring for the inside yes?

If so they are this model: TODA RACING - Camshaft

You will need to ask a Toda reseller which retainers, collets and seats they recommend.

But the main story is this is a mild valve spring, for safety I would suggest a stage one cam profile such as:

Kelford A
Drag cartel DIC
Skunk2 stage 1

etc etc
