What's everyone know about the s259 bullseye Turbo? how good/reliable, spool time, n all that. Im in the middle of a build looking for 600whp and figuring out if this is the Turbo I'm wanting to keep(since I already have it) or? Or atleast educate me about them a little more please..I see them on DSM's n **** but haven't herd anything about them on a prix....thanks guys
 


I was going to run that turbo but the internals were busted on the one I got.
I ended up buying a comp turbo 6765 and I love it. Greg badass is about to do the same one on his cartuning kit.
 
I actually just decided today that I'ma sell this s259 with the moded downpipe and the intercooler set I bought from intrigue98. I jus got the stattama intercooler,
3"downpipe, n I'm starting to think about the precision 6266 turbo but still got some looking around to do...how much HP you at on that turbo if you dont mind me asking
 
I think you're setting yourself up for a big loss on money. That kit works together and will make more power than you can put to the ground.....especially on stock trans. Run the kit how it is and then see if you want to go a different route.....just my $.02
 
current setup i have/am building...
-trans: self built(with some help from our gm tranny guys at work) stage 2 triple edge trans rebuild kit and valve body with all hardend parts, precision 3200 stall converter n billet flexplate,
-engine: stock bottom end with 80k, stage 3 heads, ST4 cam, comp oer lifters, comp pushrods, stock rockers, 3" exhaust with a cutout, meizer water pump, l26 intake with l67 tb, zzp fuel logs, #80 injectors, and dual walbro 255's for the e85 and I'm sure a few others too but im drawing a blank...
-turbo: currently the s259et, front and rear logs, z7 crossover, stattama intercooler+bov and downpipe, tial 38mm wastegate
-suspension: simple kyb gr2 struts with intrigue rear springs and stock front, gmpp front and rear sway bars, free cable mod, hoosier qtp's for the dragstrip and toyo proxes to drive on street

I have been thinking about just rockin this thing and just maxing its 600hp "limit" but on the other hand I dont want to ONLY be limited by my turbo if i can take it everything else further... that and bullseye tech support kinda pissed me off today lol. This may sound like a dumb question idk but can the l67 really take the 30psi that thing will max out at on the stock bottom end?
 


and if you have anything else you see that would be really wise/dumb of me not to do... PLEASE!!! w/e it may be let me know lol
 
Don't get me wrong here but the dream build of 600whp is a great goal to have. Some people have been able to do and and some for not a whole lot of money. BUT 95% of the people that try come nowhere close to that number. Your setup looks very stout and I'm sure you'll make some nice power.....but the ONLY thing that is limiting you is going to be the transmission. From your build list I don't see a 1" GMR chain and you're going to be inside of that transmission once a year replacing the 7/8" chain.

Have you ever been in a 500+ whp W-Body? Because I had the same goals that you had when I started my turbo build and after I got it up and running and felt what it's like to drive a turbo w-body I'm going to be more than happy with 400whp.

On major suggestion would be to ditch the dual walbro 255 setup. If one pump fails you're going to run lean and disaster will happen.
 
yea the 1" chain i know will be my massive breaking point and that's been stressing me but I havent been able to find one unfortunatly....... the main reason i went with dual 255s is because i havent herd very good things about the 340 pumps and lonnies performance has a nice setup with wiring harness n hobbs switch n all that for rather reasonable price since i didnt trust myself not to **** the bucket n stuff up lol... but do you know of any good single pumps thatll keep up with the e85 and #80's?
 
Maybe Sal (Silver2Kgtp) will chime in but I know of a few people running a Racetronix pump with rewire and boost-a-pump into the 550whp territory. Purpletrator (currently being demodded by Zach) went with the dual pump setup and had nothing but issues from the get go. I'm currently running Racetronix with re-wire...no boost-a-pump at this time as I'm still on pump gas. When I go to E85 I'll be adding a boost-a-pump and that's it.

My advice would be to get the car up and running on pump gas first before really sinking a ton of money into other areas of the car. See how you like and and then go from there. Making the swap to E85 is as simple as ordering the dual setup you were hoping to run and re-tuning. I think you'll be impressed with what it will do and what it will feel like just on pump gas.
