Also, there's no removing 5 bolts..you must be referring to older subie pumps like in my 05 STi.\.

Nope, I was talking from experience....'12 Evo X :P

The older STi's also have a bunch of bolts you need to remove to pull the pump out, which ended up being a PITA because they were very fragile...but how are you going to compare an EVO to this car which is completely different?? lol

There is no way anyone has swapped a fuel pump in a BRZ/FR-S in 15 minutes.

Holy incorrect information.

There's no need for the OP to change his fuel pump if his tuner didn't tell him it was necessary. You need to push this platform beyond what he's running to necessitate a fuel pump change, especially given the fact the kit was designed using the stock fueling.

Greddy's stance is if it ain't broke, don't fix it. There's no need in adding variables that aren't necessary.

For a first timer changing the fuel pump on this platform they should dedicate at least an hour and that's if they get the factory sock and o-ring song and dance correct on the first attempt and then there's the pesky gasket to contend with and the cutting of the factory fuel filter from the fuel pressure regulator clip. Any screwup in assembly can lead to a drop in fuel pressure which can be catastrophic.

There are certainly not 5 bolts and it's not a simple plug and play job. There's only 1 bolt, the bolt holding the rear drivers seat down and that's the easiest part of the job.

Personally, if the OP didn't install the fuel pump prior to tuning, such that any incorrect installation would be caught on the dyno, I wouldn't bother with it. I'd go with larger injectors, which require scaling and retuning, before I touch the pump. It's simply not necessary for most base kits on this platform running pump gas.

What's an frs baseline on this dyno?

Nice! I'm interested to hear about your experience with TSM. They're the closest, most well known tuner in my area but I am a bit hesitant to use them.

Here are some stuff on another local forum. http://wrxatlanta.com/forums/forumdisplay.php?f=128

Direct injection normally runs out of pump before injectors. Whether in tank or HPFP. With there being a duality of injectors, I am sure someone will figure out some slick tuning for them that squeezes the pump out. Also, the dw65c runs a lot smoother than most OEM pumps. Also, better safe than sorry,

I just saw the sending unit etc and it looked really similar. Regardless, you just pull the back seats out and it's right there.

Close to 300 whp at only 7 psi and stock fueling?

Uh, want.

I've ran 540cc injectors and 770cc injectors on 93 octane and haven't neared the point where I'll have to replace the pump.

I've replaced the pump just to mess with it for a dw65c and swapped back to stock. For awhile I had 2 canisters that I would go back and forth with while testing.

The dw65c is a decent pump, however the pump on this platform isn't a slouch nor is replacing it child's play.

Search on this forum and you'll find examples of people who had problems with replacing the pump and those who loss fuel pressure due to incorrect installations.

If you're saying rather "safe than sorry", any fuel pump can go out, whether stock or aftermarket.

In some instances, built motor, flex fuel, etc. the pump may well need to be changed. However, where the bulk of the FI owners will be, it doesn't.

Change the port injectors under the hood, leave your back seat alone, drive sideways and smiling.

You talking about "STi" or "STI" because Subaru did change it!

Sorry, off topic.

This is really irrelevant but yes I forgot they changed that. Either way, I was referring to my old 05 STi which is yes, STi, not all caps.

Evassive Motorsports tuned one to 270 whp on 91 CA piss gas. That is pretty darn good. Looks like you can get an estimated extra 20-30 whp with oh-so-sweet 93 octane!

I was saying better safe than sorry for fuel pump because of LPH fuel cut. What is the stock pump rated for? Also, I don't normally like people to be nay saying me and there are two sides to everything, but you have been very informative.
