question on forged internals

[zzcamaro00]

first off what else is recommended besides forged internals? internals meaning crank, rods and pistons.

two, does my valve train need to be upgraded as well? valves, lifters and springs? rods?

cam? do i need to change that as well?


i dont want to be driving a fire breathing monster yet, im aiming for 300 hp.

mainly what is absoluty required to achieve my goal?

Re: question on forged internals

you dont need forged internals for 300 hp...forged internals do not give you any added power, they make the parts so that they have a significantly increased strength making them hard to break.
If you are going forged internals it is because you have already upgraded your valvetrain and cam and have most likely gone FI and looking to up the boost quite a bit. Your motor will be pretty much fully built or there is no reason to get forged internals unless you like wasting money.

Now, what are you looking for 300hp at the engine or wheels...300hp at the engine (or very close to) can be achieved through bolt ons and an aggressive cam and some good tunning...

Re: question on forged internals

i already knew FI didnt add any power just strength for the beating. im looking for close to 300 at the wheels. but lets say i go turbo with just LT headers a wide band and the necessary ****. im looking to go custom remote turbo w/intercooler although it isnt necessary.

if i go full bolt on w/cam and tuning. ill also need rockers and springs and rods to take the beating from the cam. lets says i get a good set of rockers and spring and rods and an comp cam for example. i can do the install my self but what am i looking at parts cost wise vs just a bolt on rear mount turbo?

Re: question on forged internals

to do a cam you only need to replace your valvesprings, retainers, cam obviously, and I reccommend the timing chain...then all your gaskets that you need...stock rockers are fine...bolts ons are needed doesnt matter which major route you intend to go.

You need to break down what your goals are and how much you are willing to spend...a cam NA build is significantly different then a turbo build.

There is a car on abbott racings site, full bolt on, abbott cam, ported intakes, and abbott stage 3 heads...puts down 271 rwhp and has run in the 12's...there is another guy on FTV6 that has stock heads but cammed and is putting out 280 something to the wheels if I am not mistaken...

you need to start doing some research and figure out pricing and what exactly you want to do...and how you are going to tune and such...

280 to the wheels without headwork is not correct unless I have been hiding under a rock

you can throw all the money at a car if you want and still be slow. You need to know how to get the power you have to the ground, a less hp car can outrun an inexperienced driver with alot of power.

it was stock heads because of the class he ran in, but he raised the compression ratio via the pistons...give me a few minutes and I will dig up the article if I can find it... I believe it was 280 something to the wheels...I could be off a little...

Re: question on forged internals

found it, Heck you posted in the thread travis lol...I was right...281rwhp and 298rwtq...here http://www.fullthrottlev6.com/forums...ad.php?t=47448

I just wanted to brag on some numbers a customer of ours made with a 3.8 we built him recently. He runs a restricted class so we couldn't do any port work on the heads or the intake. Its got Diamond pistons with the stock dish 3.82 bore, total seal rings, stock rods w/ARP bolts, the crank has been offset ground .013", angle milled heads(52cc chambers), 11.2:1 compression, 28lb injectors, stock ports with bronze guides and SI valves, stock rockers, our NA cam, exhaust manifolds, stock Y-pipe, 3" catback, stock air lid w/silencer, 3.73 gear, 5 speed, and of course a few "stocker" tricks by us. He ended up tuning on the dyno for 5 hours until he got it completely figured out. Anyways, the best pull was an astonishing 281rwhp/298rwtq with the horsepower peaking at 5700. This engine ended up going together really nice but we never expected it to make that much power and needless to say the customer is extremely happy.

Re: question on forged internals

ok yes that is not a streetable car though. That is what I am getting at. Also that engine is not stock stroke either, they made it into a stroker with messing with the crank.

race gas, and such.


BTW, I trust no engine that comes from lance and those guys. My engine that he built for me, resulted in my current avatar image after 10 minutes on the dyno to get tuned. 2-3 other engines that they have built did the same thing or had similar issues.

Re: question on forged internals

just putting it out there the results that can be had depending on the plans and goals set for the car...that car runs on 100 octane gas so ya it's not streetable...but just pointing out there is more then one way to reach his goal of 300rwhp and impressive numbers non the less...he has to choose a path that best suits his end goals for the car...

Me personally, I like N/A builds...I have always felt it takes more work and skill to pull the power out of a car that is NA as opposed to FI...I'm actually doing a similar build to you travis, except I wont be spraying nitrous on mine....and I most likely wont be going the holden route anymore unless I can find another deal. The australian guy refused to ship to me last time...But I do intend on doing stage 3 heads at this point and upping the compression ratio as high as I can go, and still get away with 91 octane gas...

150 shot nos until it blows :rock: :rolleyes:

Re: question on forged internals

stock cast internals are good for 6500rpm and over 400hp

i wouldnt worry about having to get forged stuff

we call it nitrous around here. unless you have a 14 inch double stack on the hatch of your car.

or that route wouldnt be a bad a idea either venom. but thats if my cobalt was availible to drive when i wanted it. stupid sister


im thinking about getting a small turbo probably from a mitsubishi or something, a simple boost controller and enough exhaust piping to do a rear mount. i would get headers ofcourse and delete away my cat. where in the hell would i find an oil feed line that long to get to the turbo? my friend could tune it using hp tuners he got on his laptop. but keeping it a lower boost like 7psi and pray it dont blow up in my face.

i will look into cams but i really dont feel like tearing my engine apart. i could do it in a week end.

whats the maximum lift i can get before i must swap out those rockers if i go cammed? letsride.

cam98aro...our stock cast internals can handle that? if they do ill just go turbo.

Re: question on forged internals

oh and by the way im from houston and the guys i role with are called GM of houston. visit gmofhouston.com if ya like. mostly ss s/c and t/c cobalts there two of which are putting 300 at the wheel full bolt on and tune. there are two gtp 1 s/c and 1 t/c 1 sky and 1 soltice. our last cruze almost had close to 40 cars and 60 people.
