Wow I have to be honest here...the response from everyone has been overwhelming. It's pretty neat to see this on a car you own. Thank you.

Here are the details for those that has asked

WCCH heads with new valves
Fast intake
Katech tensioner
Dewitt's radiator
Katech Valve covers
K501 cam
C5R timing chain
Ati damper
High capacity scavage pump (added)
GM high speed lifters (added)
C7 upper control arms (added)

Already on the car:
380mm brembos
Brake duct cooling
Halltech intake
Cup wheels and tires
Caravaggio seats and str wheel

reasonable suspicion

No headers?

Katech 56... Hope you like being pampered while your Z becomes something really special..Now all you need to do is come to track attack and show her off..

Sounds like right around $30,000 for a Katech build...

At least you know it will be done right.

update....

450rwhp..not too shabby for a baseline....

However...it seems like my decision to act now have been vindicated. Guides are showing some wear as the valves appear to be "loose" in the guides. WCCH will provide measurements. I already was anticipating new valves as a potential but now its a given. Additionally, the engine oil pump has some amount of small metal pieces lodged in the pump intake. Also the lifters had a little too much scoring for comfort so I am adding the following to the mod list:

new high flow scavenge oil pump
new lifters

Sounds right on, I always see 445-455 stock on "true" dynos. I always get a good chuckle when people put down like 480 stock and think they just got a good one.

Keep the updates coming, always great to follow.

Kind of gives a rise in the levis watching a build come together

Looks like you'll be done before the weather has a chance to taunt you. Hopefully they fix the roads so us Michiganders can drive soon without having to weave through potholes! Hope it all goes well.

Believe I saw your car when I was at Katech last Friday. Dropped off my Z for some Katech mods as well. Very impressive facility and Jason has been very straight forward to work with so far. Very interested to hear how your build goes

They installed the K501 for me last year with a new engine build you wont be sorry with the choice. The car pulls very strong at the track, the thing that is different over my last cam is that it doesn't seem to loose power as you get into the top end. It seems to pull and pull forever, it really never feels like you are flattening out on the power.

Hello Supermoto17, What are you planning on your ride?

cruzin2

That's what I have been told....can't wait!!

Congrats on the build. Why did you not opt for longtubes?

Subscribed as well... as another Metro Detroit resident, I will keep an eye out as well.

When they do the work and provide the parts do they warranty no more valve issues? Not trying to be mean but with all the work being done who pays the bill for a new motor if the "fix" does not "fix" the issue? I might have missed it but I do not recall any vendor standing up to their "fix" with a real warranty that tells me if I have another valve related issue they will repair the engine. I would think that 36/36k for a stock car or with their recommended parts/tune should come with the "fix".

Again not trying to start a pissing contest but I would like to know how the repair shops stand behind their work/part selection?

cruzin2

I think your question is valid and I am not offended. Katech does warranty their work so there is that and they know LS motors pretty well. Additionally, having been in the industry for years as an engineer I have more confidence in the fix. If you look at any edlebrock head or any other high performance aftermarket head supplier you will see bronze valve guides. The reputation of katech coupled with seeing the direction of the repair fix fitting what I would have done myself gives me that confidence. Let me know if you have any additional questions

cruzin2

Ya know.... That's an option for the future for me but honestly the car is already pretty loud and at the track HP is not my problem before the h/c package. (I'm one of the fastest cars out there at my local hpde <excluding katech's track attack>).
My issue was really the heads and since I was into the motor figured I might as well do the cam. Slicks would do more for me than long tubes. Not ready for that either!!
