That should put me over 400 and keep my motor safe from preventing knocking

What kind of manifold you are using? I assume its a cast iron log manifold? If that is the case, regardless of what turbo you use, you will likely not make anymore power. The log manifolds just do not flow as they should. Also I wouldn't use a meth on street car to increase power as it could be dangerous.

And even the name brands have known to shit out quickly. When a turbo goes it goes regardless of it being eBay or big name. But I also believe meth is smart bc it's proven to make more power and keeps things safer when running pump gas. I take no offense to your comments and advice. What you have said is true but I'm a believer in, "if it ain't broke don't fix it" just so many options. A meth kit will run me close to $500. Comp turbo will be slightly more. I know people with good turbos make 400+ on 12 lbs so ik my turbo is limiting me. It would probably be smarter to just upgrade the turbo but requires more work.

Excuse me, but Garrett GT turbos can last 300k miles.... Please don't compare a $1400-$1500 turbo to an eBay turbo that probably cost less than $500. The issue with mean. Is if you tune for it to increase power and run out of it without realizing, your motor will blow.

No need to get upset. I was just saying I've seen precisions go out after 30-40k miles. Just stating that you can get a bad big name just like you can rarely get a good eBay.

A Precision is not a Garrett. Precision is a knock off brand IMO. Borg Warner and Garrett turbos are found in OEM applications. You will never find a Precision turbo in such an application.

A lot of people dick ride precision, so I use to think they were top of the line. Ill probably go with a compturbo to be honest

Of course there will always be horror stories if you look hard enough, but several issues with big names compared to hundreds or thousands of horror stories or issues with eBay turbos......well the numbers will speak for themselves.

Anyhow I agree with everyone else, get a tubular manifold and a good turbo and you will meet your power goals. Stay off meth it's all bad!

Very true, however precision is a great company as well. Newer, yes. But they have some serious products. They've had to endure some learning experiences the hard way, just like many other companies. As long as they do right by their customers, they're good in my book.

Comp is greay too, people used to bash comp a few years back as well. But if you're going to spend the money on a new turbo, DIRDIO. Do It Right, Do It Once. Get a ball bearing, and never look back. Prone to far less issues, and much longer lasting. It will outlast your car without a doubt, if you treat it right.

With you 100%!

To add a little more to this, the reason why a lot of people recommend/think precisions are awesome turbos is because a lot of race teams use them. They use them because they are cheaper and the journal bearing ones are easily rebuildable. These are 2 nice things for some, especially doing drag racing, that doesn't care so much about transient response of the turbo or things like water cooling since they are only beating on it for 10 seconds or so at a time. Most of us on here DD our cars and are not professional racers, so the ball bearing turbos, especially the water cooled ball bearing turbos, add some really nice benefits to street cars. You don't need to use a turbo timer, the turbo will be generally cooler, you get better response from ball bearing turbos so you can have fun on the street more easily without having to worry *as much* about being in the appropriate rev range or waiting for your turbo to spool for very much time. A couple weeks ago, I rode in my buddies car, he has a built motor with turbo cams and a journal bearing 6262, for the first time in like a year+ and since at this point I had now had a GT30 on my car for over a year, I really noticed how laggy his 6262 really was. When I rode in it the first time a couple years ago, I didn't notice it at all because I knew no better, but there was a truly noticeable lag even if he went full throttle immediately. My GT30 spools very quickly I never feel as though I'm 'waiting' for it to build boost, even with just a bit of throttle input the vac gauge will instantly go to 0 and start building boost in less than a second.

Log mani. And I'm probably going with the compturbo 6465 billet ball bearing still comparing though. 3 weeks ago when tuned on 13 psi I made 373 and yesterday on a Dynojet (for shits and giggles) I made 268. I was tuned on a mustang Dyno. I'm still mind fucked by this

Maybe you have a really bad boost leak? If you're keeping your log manifold, you're not going to fit a 6465. And why would you want a turbo that large anyway? Isn't that like a 1000hp turbo?!!

That's a huge turbo, I'm running a comp ct4-6062 triplex ceramic ball bearing billet turbo and I will make over 600 easy, but I am a little concerned about lag, as I was so used to my 30r spooling as soon as I even thought about touching the gas it seemed. That turbo is large and you should reconsider the size turbo your looking at.
