Hey hsvanthony,

In regards to your questions/statements...

"Put me down for a set if you could get your bank details to me via pm or something?"
Done

"and how much extra for postage"
Postage for these is usually $22 depending on the state

"does this come with everything i need to just take old ones off and replace them apart from the value springs of course?"
Correct

"should i pay first then wait for mailing very keen to get these in the car asap lol thanks steve"
We require payment up front before we mail off the rockers, which are sent via registered post.

If you have any more questions please don't hesitate to ask.

Cheers,
Steve

these are gonna be good fun with some boost thrown into the mix!!!!

I'd say us turbo guys are going to be getting a fair bit more power than the 10rwkW, as the snails are just going to compensate for the extra airflow by spinning harder to make the same manifold pressure... yay for turbos

[LX_HATCH]

Yeah I was reading somewhere on here most people get about 3 times the extra power if the car is blown or turboed. i.e 30-45 extra rwKw

[MACE]

Yeah boost with these rockers certainly helps

Cheers
Steve

[hsvanthony]

whats turbo set up cost for a vr?

[MACE]

All the rockers which have been paid for have been sent out today (with the exception of one NZ order). This leave 2 spots remaining.

ive installed these today, which was a straightforward job
buick engine seems sweeter, more willing to rev
still need to get cat back exhaust currently got extractors 2.5 sports cat, but 2 1\4 whisper quiet system
also got cai and memcal (do memcals actually work?) i noticed no difference
also a lpg vehicle (suck through type, very restrictive diameter intake) i took this off and noticed a big performance difference on petrol
im hoping for a bit more from the exhaust still
overall i think its a very well engineered product and is worth doing at that price for surehowever with any motor performance upgrade its all about the sum of its parts, no one thing gives massive gains, everything has to be done to work together (synergy?)

im curious to hear about other peoples results from the rockers

Hey vnmanual,

Glad to hear you're happy with the item You'll find that a cat back exhaust system will certainly make a noticeable difference given your current mods. Another thing to consider would be to remove the bell mouth installed in the manifold. This will certainly help to gain a few ponies top end.

gonna put mine in this week just gonna check that everythings right and then should be installed by the end of the week ill let use know how i go
btw i cant remember what my car was like without the chip is it worth having in? :S and if i take my bellmouth out will this help or just fk the motor in the long run for stuff all increase as if read here n there? thanks

[LX_HATCH]

I have fitted mine up, engine revs out much better. I changed the oil with 10W40 Magnatec and I think the rockers (maybe lifters) are making a tapping noise.

Should I use a thicker oil?

Any suggestions?

Depends on who you got the chip from as the rockers will lean the mixtures out a little top end.

I think you’ll find with the rockers, removing the bell mouth will genuinely help given that it’s now the more prominent restriction in the inlet manifold. The car will idle a rougher though. If you have a little time up your sleeve you can try testing the difference yourself. If you’re not happy with the removal put it back in.

Glad to her she's got more go now

Assuming everything has been installed correctly, that oil is definitely on the thin side. I would recommend, at the very least, sticking with the factory grade 20W50 oil if not a little thicker (depending on how many k’s the engine has done). This is regardless of the ticking noise (though it would be contributing to it) as the thinner film of oil would not offer as good as protection as the thicker stuff considering the engine was designed to run on thicker oil.

If the engine was rebuilt with tighter clearances then it would be fine to run the thinner stuff.

The increase in valve train noise could also be attributed to the stiffer valve springs you’ve installed on your engine, but without having heard the noise it’s hard to say.

Please keep us posted

[LX_HATCH]

Yes im preety sure I have installed everything correctly. I will monitor it once its driveable, im having some clutch dramas atm, and get back to you maybe even with a video.

The engine has been factory spec rebuilt 5000km ago.

Ah glad to hear it's all sorted

I'll make a note of this when we do the ads on our site.

Took it for a good drive this arvo and the noise has come back, the rockers are only just touching and it only occurs when the engine gets up to temp.

Im going to take the rocker covers off, mark where the roller rocker tip is and then die grind off some of the aluminium on the rocker cover for clearance. The covers are about 3mm thick so there is plenty of meat available

Will keep you posted.

Any news?

BTW how do you find the gaskets that come with the the KillKenny rocker covers?

Cheers
Steve

[karlos]

If you run two cork /rubber gaskets it will give you the clearance needed,had the same issue on my car.All you need to do is get some bolts 3mm longer for rocker covers.Another option is to get rocker cover spacers but will obviouslly be a little dearer,about 60$ a pair from memory.

[LX_HATCH]

Its not hitting on the top but hitting on the injector side of the rocker cover. I die grinded some off yesterday but didn't get it all fitted back up.

As for gaskets I called a local autobarn and they are going to get back to me today.

Karlos what car did you have the issues on?
What rockers were causing the issue?

[karlos]

My old VS,FIT rockers and these covers.Was not heard of before apparently.

Killkennys used to hit on my 308 aswell with yellaterras,same fix.Killkenny Castings have bad batches from time to time with everything.

[LX_HATCH]

Yeah they are still hitting, and yes there is a slight mark on the top of the rocker cover, so I will be getting a new set of gaskets and doubling them up as well as giving the injector side a good grind.

DO any of the big auto stores stock them?
Autobarn were meant to ring me back today and didn't bloody call!

What about spacers?

[LX_HATCH]

Got some more info.

Autobarn can get the gaskets (~3mm) for $25 each. I called a local gasket place and they can supply me a 1200x700 x 6.4mm sheet of cork gasket, so I will be purchasing a sheet and cutting my own gaskets.

I will have heaps left over so if anyone else needs 6.4mm cork gasket for Killkenny rocker covers I will be able to make them up.

Autobarn can also supply rocker cover spacers for $90 a pair.

Hopefully I will get the covers fitted tonight with the thicker gasket.

Sounds like you are on a winner there Ryan.
Good Luck.
