recommended pump/injectors for vf52
 

so i picked up my vf52 from the post office today. going with the advice of several people here along with efi i'm going to do tmic, ebcs, fuel pump and injectors. christ this is getting out of hand! :spin:

anyhow, what are your thoughts on pump/injectors, have any reco's? also am i good on the stock oil line to the turbo provided i keep the banjo bolt clean (or removed?) or should an aftermarket line be on the list as well?

thanks kindly!

DW 740's and a Walbro 255 pump should do the trick. I loved my VF52 with my EFI tune.

Why get a Walbro 255lph when you can get a DW65c?

FWIW, you don't really need fueling with a VF52. It runs fine on OEM fueling, and you're not leaving much on the table (unless you go E85). If anything, replace the fuel pump and keep the injectors stock.

Stock injectors work fine with a VF52. I would recommend a DW65c.

Stock injectors for Top feed 07+ work fine. I could be wrong but side feed's on the 05 aren't going to flow enough to get anything out of the VF52. I would honestly check with EFI. I ran stock fueling and the stock FP but like I said I had an 07.

Yeah, you're wrong. From what I can find, 05-06 side feeds are 535cc, 07-09 top feeds are 560cc. Not a huge difference. The BNR Evo 16G I ran on my 05 has very similar power output to the VF52, and it ran fine with stock side-feeds.

They work fine with just a pump. I've seen numerous 05's with a vf52 with stock injectors. Zero issues fueling wise.

See my sig, that's stock fueling on a mustang dyno.

From what I've seen, your IDC's are pushing it if you stick with the stock side feeds on an '05. Well worth going with 740's or more if you plan to upgrade later. I've run flawless with mine and appreciate the extra head room. You'll be able to maximize your 52 upgrade as well...

Meh, 90-95% isn't unreasonable. It's when you start getting up past that that it's a problem. The only time you'd do that with a 16G or VF52 is high in the RPM range, and tuners can compensate for that just fine by tapering the boost.

Exactly. Most of those hitting 95+% IDC are doing so because either (1) their pump is failing to keep up with the injectors, or (2) their AFR is silly rich, or both.

With a little turbo like this you can get away with stock fueling. I'd recommend upgrading the pump alone. STi pump works well but if you think you might ever go to a bigger turbo or run E85, go with the DW65c.

Suppose thats fine for the street but my Legacy is strictly a track car so she sees lots of time in high revs. I'll take the extra insurance :)

I can't argue with your personal mod decisions, but I do think the "extra insurance" isn't needed. But hey, if it makes you sleep better at night... :)

You bought the wrong turbo.

It was a street car for 3 years until last April, the VF-52 is super fun on the street, but thanks for arm chair quarterbacking :)
