I often wonder this.

In the nissan world, We often added adjustable fuel pressure regulators and turned up the fuel pressure from say 3bar to 4bar.

Why dont the subaru people/tuners do this?

cause modded stock injectors are free....

cause used injectors cost less than a name brand FPR...

cause new injectors + core rebate arent that much more than a FPR...

some do, the factory FPR can be 'crushed' to bump up fuel pressure a 10 psi or so to gain a bit of headroom. Phatron named off most the reason why most don't use an aftermarket FPR.

i'd like to hear some impressions of the legacy vs. impreza... did the impreza seem more nimble? does the ride quality of the legacy make up for it? do you think you will enjoy the increase in displacement + AVCS + better gearing vs. the better mileage of the impreza? i have been debating going this route for awhile...

My WRX definitely handled much much better than the LGT, however as you stated the LGT ride quality is light-years ahead of my old bugeye. I'd always had fun tuning the Sti's & +06 WRX because of the gobs of torque that the 2.5L allows, however I never wanted a 2.5L in 'my' WRX. I haven't toyed w/ the AVCS yet on the LGT, however my STi maps generally have some minor AVCS tweaking. I'm getting ~22.5mpg from the LGT vs. ~24mpg from the WRX.

Big thanks to 5starperformance/Kingofparts, ordered the turbo Monday got it on Wed. Should have it installed tonight.

Also compiled all the dyno graph data to one graph:

Install went well, direct bolton, no issues. I took it out and drove it a bit yesterday but I haven't had a chance to log it.

i bet you'll see ~320/280 tq/hp if you're on 92... be sure and update when you get a chance

we've got good (non-E10) 93 here...

First off I'm going to do a few runs with the existing STG1 map w/ the boost set to peak at ~17psi just to give it a good comparison to the VF40 using the same exact map. I would like to break 300whp on the stock TMIC keeping it under 20psi peak, but the logs will tell the tale. Then I'll upgrade to the reworked Tuning Alliance TMIC I have.

I'll have logs up in the morning from the compute to work.

This turbo should be alot of fun.....considering all these logs were under 17psi on my same STG1 map. Per these logs I'm already on the edge of 300whp w/ just over 300wtq on my DLL software.

A peak of 278g/sec vs. 250g/sec or so before with similar temps. I can't wait to crank the boost up.

very nice... can't wait to see 18psi from 3000-5500 do you think you'll be able to get away with 16deg @ peak tq on higher boost? if so, i'm jealous...

I'm still at 11.2-11.4 or so on 93(via Innovate LM-1), so I'm still a bit rich so I don't see the timing ~18psi being affected too much. I'll get some more logs on the way home, a few dyno logs as well. Then crank up the boost.

Same STG1 map I have posted on Romraider, however boost is just under 16psi during these runs:

two runs opposite directions on the same road, showing levelness of the road & consistency of tune.


VF52(<16psi peak) vs VF40(<17psi peak):


VF52 vs. OEM 100%


Compiled data, yes I picked up ~30whp just bolting this turbo on & ~5wtq peak BUT +25wtq near redline:


Again I can't wait to push +18psi.

Ok. I used 1600kg. Not far off. Ur weight came out to be 1592kg.

The only settings I required are the drag and frontal stuff, but either way less than 320 tq/hp. Like all others, it would be nice to see 18psi on that.

All the best and Happy New Year!

Logs of the 2 runs:
http://www.box.net/shared/k6902lnjci
http://www.box.net/shared/hg50qpli46

VF52 still using the same STG1 map I have posted tuned @ 19psi peak:


VF52 @19psi vs. 100% oem stock:




Using Airboy's sheet, 50-80mph =3.08 60-80mph = 2.10


Its amazing what a little boost will do...

Looks like you got your wish. I'll need to wait for injectors to turn it up to +20psi

Yep. Nice. Almost look like a 2006 Aussie STI 2.5 I tuned. very nice. Checking the logs now. That LGT must be sweet.

In EcuEdit, 336whp @ 5710rpm & 375wft.lb @ 3914rpm. If I had the speed, it would be nice to compare. But either way, great work and demo for others to swapped. Have a great weekend.
