Ok, thanks, now I'm starting to drool!
Do you know which AFR heads and modest cam are being used? I read about a new one, is it the 205 or 225 on their webpage?

 

After finding out yesterday that I'm exempt in my area from smog regulations I'm having a 224/228 114 cam with Kooks headers being installed at LAPD as I write this. I already have the AFR 205 heads
I'll pick the car up late today or tomorrow with dyno results.
Maybe this will help with your decision

 

YES YES, please do tell!!!!!!!! I'm debating a couple different choices:
1. Cartech Heads/Cam
2. MTI Heads/Cam
3. AFR Heads/LG GX5(?) Cam

It seems the Cartech is by far the most expensive, then the AFR setup, then the MTI setup. Problem is that I've heard great things about all of them. Now if I could only see a dyno graph for each of them on MY setup we'd be all set!

If it was as easy as saying the more you spend on Heads/Cam the more power and better torque curve you'll get, but I have no wa of really knowing...

 

Do you mind sharing what you went with and what the results are so far? Norris is local to me in Orlando.

Thanks.

 

SO SO SO????

 

I have done lots of research on this, as I frequently road race my Z06. Here is the real deal! You will not touch a decent H/C package for under $5000 installed. Good luck putting this stuff together yourself...are you prepared to take your motor out of the car? Because that is what you will have to do...to access the cam and properly torque the heads. Unless you are a top notch mechanic, you do not want to touch this job.

Also, bolting this stuff on your car without an LS1/6 edit makes it worthless. The car will need to be re-tuned for maximum performance and reliability. You will be very unhappy with the results of just bolting this stuff to your car. Even with an aggressive package, you might not make another 40hp without a proper tune, let alone another 100hp. Also Long tubes are a must (another $1000)...oh, and you will definately destroy the stock clutch within a 100 miles (another $1200).

So just for starters look at spending $7000+ to get another 100 SOLID REAR WHEEL DYNO'D RELIABLE HP. Also this will void any warranty on the motor, so you better choose a shop with a DAMN good reputation that has done tons of C5's with good referrals. An additional 100HP does nothing if the motor breaks in 1000 miles, which happened to a friend of mine...had to spend the same money twice.

 

All good points...
I have the Long Tubes already and will get it done by a professional with LS1 Edit for sure. But why would they have to pull the motor?

You're right, $5,000 is what I'm finding, installed and tuned properly. The good new is that the stock heads/cam are worth around $1,000-$1,300. So the REAL money spent on this setup can be under $4,000 total, with a killer package, professionally done.

As far as replacing the clutch right away, i've been told otherwise. But I don't have experience with that so....

 

You need to remove the motor to install the cam, unless you completly remove the radiator shrowd, which is more work than removing the motor itself. H/C packages usually re-use the stock heads, they just port them and add a custom valve trains, and the original heads are usually required to be traded in or you pay the extra core charge which is not advertised, but absoutely there. You are really not buying new heads, just paying for the porting work and the new valve train.

Also, you do not get 100RWHP from just H/C alone...you'll need a throttle body, Long Tubes, exhaust, upgraded intake (some of which you already have) and most likely a modified MAF, but I am inlcuding this within the $7k.

So, now you have an extra stock cam that is worthless, because anyone who is replacing their cam and is smart will not be using a stock cam. And your clutch WILL go...so the REAL money needed to be spent is $7000+. The most important piece of advice, when you do spend the $7k, do a lot of research on the tuner...there is lots of talk about making power, but you want to speak with 3 people who have had their car done at that particular shop. Don't worry about buying parts, just find a reputable tuner and let them do whatever they need, as long as they DYNO your car with the proven power increase.

 

- AFR Heads require no "core".
- Cost is roughly $2800 for the AFRs and LS6 heads are worth $1000 (total $1800 once sold).
- Stock Z06 cams have been selling around $150 on Ebay.
- Xtreme (Tempe AZ) never mentioned having to pull the motor (but i could be wrong).
- They have also given me very close realistic numbers on the actual power. I do love the advice (although most of it I already know) so keep it coming!!

 

Many people have done the H/C swap themselves, its not rocket science, it does take patience and the motor does not have to be pulled out. There is even one guy who had very little experience with motors, followed the directions on www.ls1howto.com and installed them correctly. Do the work yourself and save some money. You will need a good tune though.
I am doing the swap in a week or two. I am using the AFR heads and cam. My cam will fairly mild as I want a sleeper, but I still expect about 60-70 RWHP.

 

I am looking at the AFR 205 heads and an AFR cam package seriously.
I wish there was a spot on this site that just put all the data together so it was easier to decipher.

 

Weedo I think your on the right trail. AFR 205's w/ 62cc chambers is what StanO installed. I think 95 Jersey is right in certain aspects. I'm in the process of this same project using a mild street cam and these heads. You will find that there is always extras that you will hear about when you get closer to doing a package. Your installer / tuner might want things like ARP stud kit for valve train, plugs and new plug wires, hardened push rods, higher rate injectors. All these little things add up but should result in a better quality product in the long run. I'm finding that it adds about another $1000 on top of what you plan on. One slight saving grace is that you can sell your heads that come off the car and re-coupe some $. Hope this helps you decide. It's a bit tough sorting through everyones opinions and deciding whats right for yourself. I'm still doing that and I'm only about 1 week out from my install.

Give Al or Shawn a call at LAPD. They will be glad to help you sort through a lot of this.
