I have been halting my decision on heads until I get sufficient real-world results that could sharpen out the lines between my choices.. Those lines are quite blurry at the momment.. I fully understand that the difference in gained performance between going with the ETP, AFR and TrickFlows are very minimal but I still want to get as much as possible out of any $2,000+ investment..! I'm still 24 and gathering up that sorta money despite my well-paying job doesn't come easy..

TrickFlows seem to have the best flow numbers around but flow numbers don't tell 100% of the story..

c5_devil... Try to check wat the octane level is on pump fuel in Qatar.. This information should help you figure out whether you can afford to have extra work done to the heads or not.. Beware of what could be advertised as the Octane level accross different sources.. There's MON, RON and PON.. Everyone in the US and everyone discussing these matters on the internet will refer to the PON value as the octane level.. Bahrain advertises MON, which is 95 in this case.. I wish it really was 95.. PON in Bahrain is 91 thus I didn't wanna go with high compression heads to avoid knocking and other problems of the sort..

 

For your budget, Heads and cam is definitely the best way to go. As far as meeting your power requirements, that's no problem. We've made in excess of 500 rwhp with stock heads ported.

 

Considering your location, what you have to do to get them installed and service after install, I would keep it simple, go with heads and cam. You will of course need a good tuner after and also headers and exhaust if you don't already have them. This should put you in the range of $5000 plus installation. Resulting in 450 HP +.
Good luck and let us know what you decide to go with!

 

Ported FAST for $800 ..!? I'm interested!!! Unless I go the L92/L76 route.. But still.. $800 ported FAST..! Please PM me info if vendor isn't on the forum's vendor list..

 

Thanx for the help guys...I guess all the arrows are pointing towards heads and cam....So i believe that's the root i'm going to take...

I have a question though, if i want to add a supercharger later on say in a year or so when i have enough money. Should my choice of head and cam matter....Or would the supercharger just work with whatevre heads or cam you have...

Someone told me along time ago that there is a setup of heads and cams made for forced induction is that true....

 

Anyone, with an idea??????

 

IF you decide to add a supercharger later, your cam choice will be very imporatant. You will want to get it so that it also matches the characteristics of the blower type, certrifugal or roots type. A cam speced for a blower, might not be optimized to work on only a heads and cam set-up though.

 

Head choice will have a tremendous impact. The cc chambers for an N/A motor will be significantly smaller than those intended to go on a supercharged car. If you buy a decent head, resale value will be pretty good so you should just plan on selling those. Also, I'm not a huge fan of running a really expensive head on a blower car. While it still can net gains, I feel buying a cheaper large chamber head and using the $$ towards the blower is the smart way to go. Now, before I get flamed, I'm not saying a $3000 head will make as much power as a stock head... I'm saying if it were me and money was an issue I'd sell the $3k dollar heads, buy a set of stock truck heads, put a few hundered in springs and valves and use the other $2k towards the blower.

Oh, I've spent a bunch of time in Quatar and its not hot, its really friggin hot. I'd hate to have my car there. Probably would only drive it after sundown.

 

lower your hp goal

you are asking for long range headaches with those mods since there is no one there to service your car...you will be sorry.

if you want big hp..... trade up to the stock zO6

 

Well i like my top off....And i love my suspensions...Those are two things i can't get with a z06......So, i am sticking with the c6 and from what i have gatherd from this thread and other threads heads and cam is the way to go...I will be doing that before the end of this month unless someone can change my mind

 

Anyone else with any ideas...how about lpe????

 

Excellent service, excellent products, top-notch quality but also a sh!tload of $$$... But hey, you're Qatari.. ;-P

 

what does that mean......I'm a poor qatari if you could believe that..... i had to wait 2 years to come up with 13000$.....And i wana spend my well earnd money wisely....

I guss i should be shooting for 450 rwhp....with this set up

heads cam pakage ( lpe, cartek,LG)
headers ( kooks/LG)
intake
Exhaust corsa sports
tune
gears (3.42/3.73)
a stall ( 2800/3000/3200/3500)

Would this be under budget or would i need more money....????

 

I have kicked around many of your concerns. I live in a small socialist country commonly called California. In the south, it can get hot in the summer, especially in the desert.

Heat is an issue, especially in the C6. After just one session on the track I can see oil temps in the low 260's. So here is what I am about to do:

A Dewitt radiator (Z51 has an oil cooler integrated to the radiator)
AFR 205 Heads
Cam specs of 224/224 560 lift and an LSA of 114( communist states like California have smog certification requirements)

IF at a later date, supercharger will be just fine with this head/cam package (so I am told) You were told right about the cam specifically for FI. You can use stock heads with any blower out there.

The above package should be good for about 440rwhp assuming you have headers and a cold air intake.

Forced induction is an awesome addition to your vette but heat and detonation are your enemies. Since you dont have a tuner who is local to you (things break) I would prolly lean to staying naturally aspirated and enjoy your ride.

 

Sorry for missing out that if you were a rich Qatari you'd probably be on the Buggati forum as opposed to the C6 forum.. :-P

I'm a relationship manager myself at an offshore bank and I handle clients from Qatar, Oman & the UAE.. Part of my job is to produce country analysis reports since I tend to grant loans to the Governments of the countries I handle..

With an annaul GDP per capita of ~US$68,500 and increasing for Qatar as opposed to US$30,000 for Kuwait and a mere US$19,000 for Bahrain I was kinda inclined to somewhat associate Qataris with $$$... Not only that but I happen to know A LOT about cash flows and big $ projects (Power, gas, oil, hydrocarbons, real-estate) in Qatar because of the nature of my job..!

Anyway, not to steal the thread.. I think $13,000 should be more than enough if you're looking at somone other than LPE.. Anyway, the LPE packages are expensive if you actually get the car sent there and have all the work done in the US, which I doubt you'll be doing!

P.S: A Bahraini with a C6 is considered rich..... No joke !!

 

Yeah bahraini people are considerd poor amongs the gulf region...

Anyways, Thanx for the help guys....But i think this would requier more research on my part........Would it just be better if stroke the motor...Say a 403 or even a 427....???

How much would something like that cost, rwhp, and would it just be better for a daily driven even if it cost more...?????

 

I've got two questions that I'd like answers to.. Just out of curiousity, how old are you, and have you modded a car before..!?!? If the answer to the first question is <25 and the answer to the second question is No then I'd rather you go the head/cam route for the time being.. No disrespect but no matter what, it's not wise to have a +450rwhp car in the hands of a non-experienced youngster..

I'm turning 25 next month and I could be quite hazardous on the roads myself despite my caucious nature!!

 

if you want a real stump puller stroke it.

properly done it will be very hard to beat. the value/performance ratio but not forgetting the drivability and durability of a stroker is second to none.

 

Well first i'm 30 years old...And yes i have modded cars before..However nothin more than 400 rwhp. So, this should be my first experiance with 450+ rwhp

2nd stroke it , Not bad of an idea but i have 4 questions:

1. do i go 403 or bigger???
2. What's the cost of it??
3. What kinda rwhp and tq am i looking at here???
4. Can i use that kind of power on the street, or am i just going to burn rubber???

 

God damn i have to learn to read ..... free bump
