quick4dr Posted July 9, 2011 Share Posted July 9, 2011 VF52 or BNR 18g? Currently maxed my stock turbo out and it doesn't hold boost very well at top end. EFI logics have recommended either turbo with 740injectors & walbro 255. Goal is 300whp and over 300wtq. What are the thoughts Link to comment Share on other sites More sharing options...
kits gt limited Posted July 9, 2011 Share Posted July 9, 2011 I have the BNR 18g billet, it is about 40 whp more then my stage 2 with stock turbo, big difference! This build: DW 740 side feed, Avo TMIC, Crawford oil air separator, Avo fuel pump, 3' exhaust. turbo blanket, Perin light weight crank, defi racer boost and oil pressure in cubby, and of course the BNR 18g billet with upgraded actuator and forced performance oil line. I added a vibrant race cat, due to droning. My peak power only had a 15 foot lb increase to 255, but I got about 40 ft lb increase through the whole power band. Keep in mind that I have 5EAT, and this dyno reads low with no correction factors, compared to most out there. Link to comment Share on other sites More sharing options...
quick4dr Posted July 10, 2011 Author Share Posted July 10, 2011 i am 5 eat as well. hows the 18g spool rate, still as low as vf series, i like my power around 2600-3500, i dont like waiting. Link to comment Share on other sites More sharing options...
goneskiian Posted July 10, 2011 Share Posted July 10, 2011 i like my power around 2600-3500, i dont like waiting. Which doesn't jive well with an AT. Just ask msprank. Link to comment Share on other sites More sharing options...
lgtgirl06 Posted July 10, 2011 Share Posted July 10, 2011 I was just there Friday. Them! VF52, 740cc injecters, and Walbro 255, FMIC, here http://i18.photobucket.com/albums/b122/Sugarsugar1211/EFILogicsDyno.jpg Link to comment Share on other sites More sharing options...
subiedad51 Posted July 10, 2011 Share Posted July 10, 2011 ^ what lgtgirl06 said. I'm loving the VF52. With that build as you can see you can get to your goals. Link to comment Share on other sites More sharing options...
quick4dr Posted July 10, 2011 Author Share Posted July 10, 2011 vf 52 is looking better and better, approx $ for vf52, dw 740's and walbro 255? could this all be installed and then babied back to EFI for a retune? Link to comment Share on other sites More sharing options...
lgtgirl06 Posted July 10, 2011 Share Posted July 10, 2011 I got the everything from Import Image. They sell it the VF52, injecters, and Walbro fuel pump as a combo for about $1600. We drove to EFI (babied it). So yeah it can be done. Link to comment Share on other sites More sharing options...
subiedad51 Posted July 10, 2011 Share Posted July 10, 2011 Well - assuming you buy new you're looking at: VF52 =~ $1,200 DW 740's ($550 plus $160 rebate back for your injectors from DW) Walbo 255 - $90 with install kit Importimage had these prices for the kit: 05-06 legacy gt sidefeed combo 1x VF52 turbocharger 1x dw 740cc injectors (they get $160 back from dw cores) 1x walbro gss342 pump high pressure $1554 + shipping This is the link - the thread is old but you can contact them, or Fredbeans perhaps for a package as well. http://legacygt.com/forums/showthread.php/vf52-turbocharger-packages-injectors-fuel-pump-ready-bolt-and-save-138047.html You can find all of these used if you serach and are will to go that route. The VF52's will go anywhere from $650-$750 used. If you're patient and search here and Nasioc. If you're going to get tuned at EFI then can send you a based map to load up - stay out of boost and you'll be fine. They can also install for you and tune. Although I believe they're not big fans of modifying the Walbro and recommend the AVO which is pretty much just a drop in but is more around $250 range.

NO NO NO! They HATE the AVO. I was having issues with the Walbro that came with the combo and bought the AVO and it was loosing fuel pressure on the dyno so they installed a Walbro for me there. They have had a braket made for them for the Walbro. DO NOT go with AVO. EFI will tell you that. Link to comment Share on other sites More sharing options...
quick4dr Posted July 10, 2011 Author Share Posted July 10, 2011 thanks for all the input, im going to try and score a VF 52 from a buddy that works in their Jersey warehouse, or my buddy who is a service manager at Lynne's subaru. do all vendors selling DW have the core refund?

lgtgirl06 Posted July 10, 2011 Share Posted July 10, 2011 DW has their own refund in the box. So yeah, I would think they all have the refund. Link to comment Share on other sites More sharing options...

lgtgirl06 Posted July 10, 2011 Share Posted July 10, 2011 5MT. I am running a RacerX FMIC too. That tune was done with my AP. When I said I'd like to go open source they said I would be much happier with the tune through the AP. Just so you know. Link to comment Share on other sites More sharing options...
mumblinaviator Posted July 10, 2011 Share Posted July 10, 2011 I've been eyeing both as well, pretty sure I've settled on the BNR 18g (non Billet), but until the money has been spent, I can always be convinced otherwise. Will have 750's, Walbro, FMIC, full exhaust work on my 6MT Link to comment Share on other sites More sharing options...
quick4dr Posted July 10, 2011 Author Share Posted July 10, 2011 im now debating swapping my IPR tmic to the racerx since im swapping turbo. But then I think fmic, means i can change to an sti style turbo. Which turbo do i do then for a 300/300 goal? with hopes of 300whp/ 325ishwtq. Any suggestions for that route? My 5eat will be getting the new valve body mod shortly, and new tranny cooler this week. With eventual plans of the new bushing for the center diff.

subiedad51 Posted July 10, 2011 Share Posted July 10, 2011 Didn't realize they hate the AVO. When I was there that's what they had recommended. Anyway, just as an FYI the Racer X can be bought to support an STI style turbo or LGT. If you're goal is 300/325 the VF52 can certainly get you with the mods you're looking. Not sure if you absolutely need a FMIC but it will certainly avoid some of the heatsoak you'd get with the TMIC. Like all builds, if you think you're going to want to continue to build it out from there you may want to consider some different Turbos. Really depends on budget and how and where you're going to drive your car. For me, as a DD that's alot of Highway I love the HP/Torque curve of the VF52. It's there when you want and need it Link to comment Share on other sites More sharing options...
subiedad51 Posted July 10, 2011 Share Posted July 10, 2011 A good place to look at some setups is the EFI dyno database. They have a bunch of LGT's on there with the dynosheets and modifications. http://www.efilogics.com/dyno/ Link to comment Share on other sites More sharing options...

quick4dr Posted July 10, 2011 Author Share Posted July 10, 2011 yea im DD, i love the driveability of the VF52 hopefully i can find a nice price, because that BNR 18g at at 725.00 is a good gig. Would the 18g be a better choice if going FMIC? Link to comment Share on other sites More sharing options...
Legend Posted July 10, 2011 Share Posted July 10, 2011 No comparison here. VF52 is far better than the BNR18G. Will spool ~800rpms sooner and make the same power as the BNR18G. Documented on this forum in 2 different threads (both use same tuner, same dyno.) The VF52 is a solid, very fun turbo. I loved mine. I also like my BNR68. More power, slower spool.
