"upgrading" from a normal 3076r to a GTX 3076 is not worth it. Going to a 3071 i don't think is wise, you'd have to run more boost to get the power no?Odin_S wrote:Hey guys could you please give the full names of the turbos, this is all very interesting.
S252 SX is made by who?
I like the idea of keeping the same footprint and just changing out the turbo.
From my trawling on Garrett forums,
Not just on spooling but it has way more punch and a top end hit for a similar sized turbo. 
.. 
..the general opinion (not my first hand experience by any means) is that they just don't make the power promised...they seem to kick ass on flow and spool. That said, I am amazed at the Forced Performance turbos- compared to the Garret compressor wheels, they are simply astonishing.ashley wrote:I chatted to a few different mappers, including Dave Rowe, about the BW's.
I would be tempted with a Precision next time round.
..just get out there and talk to folk who have experience of both...then make up your own mind...it'll be more than fast enough for the road, and will have awesome mid-range torque. You should come for a drive in mine with the GT2868HTA...it is absolutely awesome as a road going setup, easily more than enough for fast road driving and embarrassing other cars. I can't see the GT3071HTA not being totally insane, with a bit more lag...it is entirely believable that the BW are as good as they claim!(although they'll probably try to sell you one of their new turbos!), Real Street are also really helpful.

For my money- I would stick a GT3071HTA on yours.
But then I've only played with Garretts, HKS and HTA turbos.
Why not discuss with someone unbiased and who know both products? FullRace are really helpful, likewise Owen Developments will discuss it with you

, I am none the wiser and need help from you guys.$$ so i'd like the best I can get to fill my needs, dyno graphs of my current set up are showing the 0.63 housing weaknesses. On spooling and pretty much throughout the rev range, The BogWarner seems to tick all the boxes however if there is something better out there please feel free to post direct links to the turbo to help me on my way and research it. 
.. He's getting about 520/530 from the 7064 and nearly 400 from 4K rpm, compared to the graph posted earlier in this thread it blows the Garretts away.MR2 Rich wrote:There's a guy in the Cossie scene that gets some great numbers from the BW EFR's.
....but......different engines tune differently don't they....what it does on a Cossie (with mega mods?) is not a valid comparison with a Garrett on a totally different engine is it...or talk to folk who have detailed experience across a huge range of different applications and engines and I'm listening. Show me what his engine does when tuned up on a Forced Performance or Precision turbo, then we can talk about which turbos get blown away.ashley wrote:MR2 Rich wrote:There's a guy in the Cossie scene that gets some great numbers from the BW EFR's.
Yes.
Show me back to back tests on the same engine and I'm all ears.
A throwaway comparison to a single other build is just pub talk.
...'excuse the pun' in the middle of it.... , please help.... 
ashley wrote:Sounds good then.
Link to source?
, i'm not trying to prove a point but simply trying to justify why I thought the BW was the turbo that would suit my needs best, help me out of the woods dude , link me to what turbo you think will suit me best and save me from 40+ hours of research 
Vs GTX3071. On an Evo tuned by Mark Shead in the UK .Pulled from full race's website.
.. These are the same turbos that Owens said were 'lazy tractor turbos' when Sheppy tried to buy one. So as Ashley said, your best bet is to speak to someone with real world knowledge of both products - full race, AGP turbo, etc '00 Honda CBR600 Follow me on Instagram @c35rob They just tried to give me the hard sell on their own stuff. I despise that kind of behaviour so went with agp. I notice my turbo is around $200 dollars cheaper than it was when I bought it too!! For the money you're never gonna get a more capable turbo. My friend has the bigger version (the 300sx) on his mr2 and it's well over 700bhp and achieving full boost by 4krpm. Amazing considering it's for a tractor! (assuming you have a 4" intake on the garrett). I think the biggest they do is 3.5" intake. So you'll need to get new pipes made/bought to suit. a silicone reducer would sort this issue!Ryan S wrote:Scratch that,
C35Rob wrote:S252SX-E
S257SX-E flows 65lb/min so good for 625ish with the correct supporting mods, but will spool a little slower
.. I am quite happy with the way my mr2 spools now so if the latter is better but will comfortably hit 550 bhp then it sounds exactly what I am looking for. Right now I have 800cc injectors in a rev 3 rail with braided lines and an uprated fuel pressure regulator. I am running an apexi power fc. and details would be awesome... but for now i'm in for the long hall and hope I can get everything bought, fitted and mapped by next march/april.... .. .. , thanks for all the input and opinions this far folks C35Rob wrote:
..I'm impressed! I wonder why the EFR range have been slated by the tuners I've spoken to, if the cheaper range seem to have so much potential...strange! this and a Precision.(single turbo supras for example) . If you've got a business to run and a reputation to maintain it kind of makes sense to push products that people know and aspire to.. Like everyone calls a vacuum cleaner a 'Hoover' even though there are alternatives that are just as good and better. 'Garrett' are the household name of turbos, people associate with them so it's an easy sell.(not badly Re-drilled units *cough*deatchwerks*cough*) but 1/2 the price list remanufactured turbos at huge discount, but you need to be on the ball cause they don't last long!'00 Honda CBR600 Follow me on Instagram @c35robhttp://blog.perrinperformance.com/borg- ... -and-tune/ I myself have the EFR7064. thex tend to only use oil cooled chra......why on earth they do that when water cooling is more effecient is beyond me. I would never ever ever use a purely oil cooled chra when i know that i can drive for long periods of time at WOT.
