[QUOTE=CALL911]Just my opinion here, but again, if you cut corners and don't get at LEAST the pistons, ARP head studs, and RODS , even with running low boost, and a good tune, there's no garuntee you'll make it to your 3rd oil change before you need to rebuild the motor.
Its all in the tune, I can tell you for a fact that 90% of all Forced inducted cars I have tuned are BONE STOCK (less larger injectors and aux pump)running 7-9 lbs of boost making app 500 RWHP, These cars have been running strong for over 5 years and these guys do not baby them... So I have to disagree with your statement..

Like I said, just my opinion from what I have seen (pretty much opposite of you). Most guys even with a conservative tune on the stock bottom end I usually talk with (quite a few, especially on cz28.com) make it maybe a max of 25,000 miles on their stock bottom ends if they are lucky before something goes. Just what I have personally seen, and people I have talked to. I'm sure there are others on the other side of the lucky fence who have made it longer. I have yet to talk to one though, and most don't even seem to make it more than 15,000 miles.

i am getting low cr pistons, just thought the head would help as well. i think i'll get some rods too, even if the stockers would work i think i'll feel better knowing i have strong rods whenever i feel like pushing it hard

At the end of the day this thread is about investing money where it really counts imo. So you need a decent (forged) piston and ring package, maybe some nice shells and some good rod bolts. 317 heads help because of the ports as well as lowered cr but you can lower cr some more with the forged pistons. Aftermarket rods might be nice but they're probably heavier so for mild applications do you need them?

Just a matter of opinion I guess. I know plenty of guys that made only 500 RWHP or less on the stock block boosted, who fried a piston, a ring, or blew a gasket all under 5,000 miles.

When it comes down to it, this is what really matters. Opinions aside, I think we can all agree that having a fully forged setup will be more reliable than a stock one.
You can either save money and go cheep, and hope to be one of those cars I haven't heard about, instead of the ones I have heard about. Or you can spend a little more for a more reliable setup.

You can't take a dish piston motor and try to make it 11:1.

well im not sure how they do tunes in NJ,im originally from NY,but in FL many MANY people are fine making over 400 and many over 500rwhp without blowing **** up.I had a H/C/I setup and did everything they tell you not to do with nitrous(ie N20 burnouts,spraying out the hole,spraying below 3k or whatever rpm) and never had a problem blowing anything up.I can start listing people boosted or spraying making high 4xx,5xx,and some 6xxrwhp.might wanna check out the boosted lists as a starter.
and edit....tuning a car for NA(which is more than likely the volumes youre talking about) is completely different than tuning a boosted car.many tuners are great tuning an NA setup and suck tuning an FI setup.

and what im saying to you is if you have a strong motor without the power adder,ie no issues already worn down motor,and your add the power adder and your making less than 550rwhp and people consistently have problems with motors blowing up its the tuner.i am giving you credit that some just let go and have problems but the majority will not have problems if it has a good safe tune making 550rwhp or less.my lists already been started like 4 years ago..read the boosted lists,you got some catching up to do on your list 
All I'm saying is that I've seen the opposite (several people with low mileage, or good condition motors, that go FI with even a mild or moderate amount of boost with a good tune on the stock motor that end up with issues).
We'll probably just have to agree to disagree on this one

thats cool,ive seen wierd crap happen to,but people are here to learn right?believe me ive made retarded posts and learned alot on here.what im saying is that maybe what you feel is a good tuning standard might not be as good as it could be if that many motors are having problems.

Thats definatly something I can agree with. It's not a good idea at all to throw a blower on a high mileage motor, or one that is having issues. If you do, no matter what the tune, you are looking for trouble.
