Precision 6870 gen 2

Hey guys I'm new to forum and hope I've put this in right section  

Has anyone used a precision 6870 on a rb30 and had goood results?
I'm thinking of going down the precision path as all I read is great things about the gen 2 range as far as peak power at lower rpm is concerned compared to other comparably sized turbos.

Ive always had Garrett turbos and was going to buy the GTX4294 just because the spool time would be a bit better and it predominately a street car. I am chasing about 500-550kw at the treads. 

Many help would be greatly appreciated.

I'm not really hung up on any certain manufacturer as they all do great things for different setups. I'm more so trying to get a feel for precision and what suits the best turbo for my application. 

From what I've read so far the 6870 is good for about 800hp at the tyres on a rb30 so I didn't think it would be a case of "over turbo". Considering 760hp is about 550kw. 

6870 on 3L is your best option it's like a 6466 on a 2.6, you'll make the power of those smaller turbos and won't be working the turbo as hard (safer too)
it's 3L spool and torque is on your side

BTW i have a brand new 6870G2 if u like

    • I've got a Turbosmart wastegate, ATP catch can, many GK Tech parts and Haltech everything. Everything's been perfect, sorry to hear your experience wasn't the same
    • The only high-power RB I've personally seen go pop after running for all of an hour on a dyno was built by B2R, while being remotely tuned by B2R. The only wastegates I've ever had leak like a sieve, return, still leak, return and get shipped back the wrong ones were from Turbosmart. The only final drive that I've ever purchased that were unusable, twice... were from Speedtek. The only seat mounts that I've ever purchased that placed the seats in the door frame were from Crank Motorsport. The only poorly designed parts that I had the manufacturer confirm should have been designed as per what I mentioned were from GKTech. The only ECU I've had firmware updates consistently break things are Haltech. The only catch can I've purchased that didn't fit in its advertised spot was from ATP. So forth and so on... Moral of the story, doesn't matter where it's from. Do your research beforehand and stick with products and companies you've trusted in the past.    @joshuaho96 If you want it done right, do it yourself.
    • Something coarse-ish. 180 is good.
    • I was surprised to see all the quick Jack models at the same prices on there. But yeah, grabbing one at 20% off would be great.
    • I wonder if these would be discounted when they have their big sales? because if so would be a great time to actually buy them could even end up cheaper than buying from quickjack in the end.
