What's going on everyone? Going onto my third setup now and want to do it right. Had an SOS kit and didn't care for the powerband even with a smaller pulley. Had a 60-1 trim turbo gsr hatch and loved the spool of a turbo. Bought a kit from a local guy and should of asked questions but wasn't willing to remove my cross member. I decided to sell that kit. Now I have a Sheepy sidewinder kit minus the wastegate and turbo. This car will be used as my weekend warrior since I have a daily. I would like to take it to the track once awhile. The manifold is a V band and all ready have a 3 inch downpipe that came with the kit. Any advice is appreciative.

PS keep leaning towards a 6262 billet series but open to ideas.

gtx30r, efr7064, s200 7670, good old gt3076r would be great too, if u go precision the 5858 would be better for your power goals

Garrett GTX30R

Your options are going to be limited by that vband hotside.

I'd be looking @ something like a GTX35R, anything to stay away from Precision IMO

Pass I would think that a 5858 would hold me back if I ever want more then pump can give me.

Why dislike for precision?

Now I'm not going to turn your thread into a shit storm, because people have debated (argued) this on more than one occasion on this forum, and plenty of other places around the web.

What I will do, is provide my OPINION. I have personally had nothing but poor experiences with the precision turbos I have owned. The whole mess they got into with Garrett was really their downfall IMO. I see nothing but failure after failure, not only with the local cars I work on, but scattered about this forum as well. They aren't what they used to be in terms of longevity and quality, especially when compared to something like a Borg or Garrett.

There's a reason places like Evans, and Full-Race no longer recommend them to customers...

^^ thanks illstrolla your opinion has been noted. Never ran a percision turbo but my garret lasted 20000 miles till I sold it and lasted my friend another year till he sold it.

For your 450-550 goal I would say a GTX3076 .82 AR T3 is perfect. I have a V-Band Flanged GT3076 .63 and made 424pump and 507race with evans and that was the limit. A GTX30 will have no problem making mid-high 500`s and be much more responsive than its competition. But your gonna pay to play... If you dont wanna spend that much my second choice would be a Borg Warner s200 series or small s300 series turbo. The Borg FMW wheel is a great turbo but to big and laggy for what you want.

Since you have sheepy making a custom manifold see if you could get a borg warner efr series. Have heard nothing but amazing things about them. And also you wont have to buy a boost solenoid, bov, or wastegate since its intragated in the EFR series.

With that said I suggest anything besides a precision/comp/or holset turbo

i spoke to a friend who owns a shop and sells precisions about what he thinks about the precision failure issues, he said its the journal bearing precisions that fail a lot more than the ball bearing ones, he said the ball bearing units are solid and have been on par with the other companys.

I also recommend to stay away from precision because it seem that their turbos do not last. I only run Garrett turbos and they always late 100,000+ miles.

For your power goals of 450hp-550whp it depends on the type of fuel you will be running.

If that goal is with e85 or race gas then the best turbo is a gtx3071r

If that goal is on straight 91/93 octane gas them your going to need a perfect engine/turbo setup with at least a gtx3576r or a gtx3582r.
