Our stock turbo tunes were weak though so possibly not the greatest comparison. That one of yours definitely did have more midrange and torque than mine though.

2 months later and I finally got a fuel pump for this thing. I'm glad I found the limit of the stock pump on my setup, but only driving this car around at 22psi is just silly. I went with the Deatschwerks DW300 and MAP's evoX fuel pump adapter kit. Install was a minor PITA but an extra set of hands made it pretty easy.

Stock assembly, partially taken apart:

MAP assembly w/ DW300 pump. I ended up rotating it slightly to fit the filter in the hanger better. The MAP kit is nice b/c it locks the pump in place:

Coiled up, no kinks!

Then a few other things to get ready for spring. Bled the brakes with fresh ATE blue, checked pads (plenty of meat left on DS2500s), swapped on the rotas/sumis, cheese fries and cherry coke at checker w/ spaz, swapped gear oil in the rear diff....ATF fluid drain for the AYC was stuck (bent my cheap 10mm allen), topped up xfer case, and just generally checked things over from the bottom of the engine bay--no leaks yet!

Went for a quick test. Car runs just as before driving gently. DW300 pump is *silent*. Under WOT, AFRs are consistently half a point richer across the board and a full point above 7000rpm. Step one, check! Step two: moar boost! I cranked up the MBC 2 full cranks. This results in peak boost right around 25.5psi. Third and 4th gear the car holds about 24psi. It feels like a new monster has awoken from within!

On the dyno, with an extra crank and some on the mbc the car would do 27psi peak and taper to 22-23 IIRC. I'm going to lean out the afr a little and leave the boost right where it is for the cruise in two weeks. More to come after that, gotta do something about this pesky maxed-out maf sensor before dyno day :D

Thanks again for the help spazzy!

YUM, cheese fries FTW!

DW300 pump is *silent*.
That's good to hear! I think the X insulates pump noise quite a bit better than previous generations (the plastic housing can't hurt) b/c I've never heard my Walbro or Tom's Bosch either.

Looking at your pictures, MAP could easily just lop off that whole lower porting of the aluminum adapter to save on materials, cost, etc.

Thanks again for the help spazzy!
No problem, sir!

Nice work.

[awd-drifter]

very awesome. more fuel for the monster!

Actually the pump slides down in there and there is a small bevel at the bottom to keep the pump from sliding all the way through. Then there are a few set screws/locknuts on the side (that hold that plastic ring as well) to keep it from spinning within the housing.

My only complaint (and this will be no different from any other pump kit) is how the filter gets smashed up inside of the plastic housing...the stock pump has a round filter on it, if they could find one that worked for this application it would be awesome!

[Kracka]

Ahh, that makes sense then. Agreed on the filter!

Spring is late but right on time for my budget :D Been slowly making plans for the next steps, all of which will be unfolding over the few weeks! Started with that DW300 fuel pump about 3 weeks ago. Car has been running perfect, like stock pump but with more fuel capacity. I finally got to turn the boost back up to 25-26 peak but still couldn't utilize my hybrid BCS setup due to my MAF being completely maxed out. If I did any tweaking at all to boost, it would invariably flatline at 5v from 6000rpm+ and no matter what I did there was this little boost spike at like 6500rpm.

With the added boost, I finally burned through this coupler that is who knows how old:

The car was at Primo for their up-and-coming 2.75" LICP (no pics yet sorry) and picked up one of their 3.5" intakes just today. I ordered a generic-sized aFe 3.5" pro-dry filter to go with it as it is IMHO an evolution of the tried-and-true K&N.

We had originally talked about them doing a custom intake for me to keep the stock BOV placement, but after thinking about it I decided to just go with their standard setup and ditch the like 30 feet of pressurized-hose from the stock setup.

This is a *really* nice piece! Install was simple, I did it over my lunch hour. I had my laptop with me and rescaled the maf initially to 1.48*stock maf tables. I tweaked to 1.45 and might drop to 1.43 to get it juuust right for my car. Higher was safer, so I started there, but all in all I have about 25 miles under my belt with it already and the car starts, idles, cruises, putts through stop-and-go traffic, and idles down my alley just like it did with the perrin/aFe intake: very very nicely!

We have a few fan shield designs to play with in coming weeks but its not quite warm enough here for necessary AC usage yet so I'm not too concerned. I'm stoked it uses the stock air scoop though.

For exactly two revisions of ecuflash, I'm *extremely* happy. Stock-like driveability, fuel trims are already down to -2.8%, afr's are nearly where I want them, and boost is a tish smoother (no hose going back into intake anymore, I think thats why):

Today is monday--saturday is the spring dyno day. I plan on tweaking AFR a tish more this week and seeing if I can't get boost to stay nice and level ~26psi at 8000rpm and see if we can't get into the 41x whp range at DB this weekend on just pump gas and the DW800cc injectors (which are just touching 100% IDC).

Next week (or I guess this weekend if nobody signs up for the dyno day), these will go in :D
