Consensus is that any forged rods are adequately strong. The ones on ebay are the cheapest. It's recommended that you purchase ones with arp bolts if you go that route.

Yeap. Have run ebay rods to 8,800 RPMs, 30 PSI boost without a failure. Have pushed carillo's harder without issue, but would not hesitate to run cheap rods again.

So, what do I need to build the motor to handle 300whp?

Rods, pistons, new damper, valve springs? what else?

Manley rods are available from several forum vendors for less than that. The "eBay" rods will be $300 or less. Brands like scat and others I think. I believe Manley h beam is the standard rod used for trackspeed engine builds.

This has been discussed before. You might do a search and see what people think, opinions vary on what is needed vs nice to have.

Rods only for 300whp if you're cheap cheap cheap. I've done this a few times, it worked well, but I broke stock pistons around 350whp on pump gas. I think with E85, they're stay together at 350whp. There's two people I believe on the forum doing exactly this right now. I now have a $$$$ motor with all the things.

Search brah, it's been discussed before in detail. It depends on your other goals, if your going to rev high, or run e85, or track the car. Varying levels of build, although the differences aren't huge, unless you start getting into lots of head work.

well, 300whp is where I would cap out. I don't want any more than that. I should probably search this but...how long will the motor last with just rods at 270-280whp. This is my daily sooo...

With a good tune on pump gas, many years.

With a good tune on E85, forever.

Crap enough tune, seconds.

Ya I should probably search this up. Higher revs is always a plus. Maybe e85. Def tracking the car tho.

Awesome. I think I may just do this actually. I can get e85 near me too so that shouldn't be too much of an issue.

The you say good tune, do u mean MS auto tune or pro tune. I assume the latter.

You could tune the MS to be safe, it takes a lot of time/reading (searching) to learn how to do it. It's what a lot of people do, it's what I've done for years. A pro could do it as well if you'd rather save the time and know it's done right of course.

First you need to buy another vehicle you can daily while working on this. Ever turbo'd a car before? Cuz it isn't as easy as you're making it sound, even if you start with a kit.

I have access to another vehicle if I need it. Not an issue. And I don't expect this to be easy either so....ya

The real first thing to do is start searching and reading.
Then do it again for hours and hours and hours.
Then come back and have a pretty good grasp on what it takes, and have much better questions that we will gladly answer for you, because we will see that you're serious about doing this and did the initial leg work.

It's right there in the classifieds.

I'm mostly joking though, he really doesn't need a 6758. But most end up with one after swearing up and down that they "only need 200hp". So this might save you the time and trouble. With these new tech turbos boost threshold is quite different than an old garrett.
