‘08 Legacy 2.5i turbo build - Page 2

pcampbell · 09-04-2019, 02:14 PM

I think they switched to returnless in 2006 for many cars, A return style has 3 lines. 1 is supply, 1 is return and 1 is Evap. You can tell by going to RockAuto and looking at the fuel pump module, or.... in engine bay 3 hoses would be return style. I have no idea how to tune a returnless system but I am sure many people have done it successfully.

I disconnected the hose I thought was return and it’s definitely evap, no fuel. I’ve had this car tuned multiple times, no one has ever mentioned returnless being an issue?

pcampbell · 09-04-2019, 08:17 PM

Yeah I don't think it will be much of an issue.

Hi tipsymechanic, awesome build.

I'm assuming you did engine management yourself. How did you adjust your ROM for the larger fuel injectors? Any guides anuwhere about this?

I'm going to slap on a used raptor SC kit soon with wrx injectors onto an ej253 and need help since I don't have a base map.

Hey. You’ll need the flow and latency values for your injectors and you plug them into the respective tables in romraider.
There’s a lot of good newbie tuning info here: https://forums.nasioc.com/forums/showthread.php?t=1626520

Have you had your ECU defined yet, so it can be tuned? PM me if you need more detailed help.

I have not had my ECU defined yet. Still waiting for my tactrix cable to arrive. I'm getting some stock WRX injectors so I'm sure it should be easy enough to find the flow and latency. Thanks for the help, I'll pm if I need more help as the project progresses.

Cool. You’ll also need to re-scale the tip-in fueling, cranking tables, and a few other things fuel related

Do you think the larger type 14 Awic would fit? I was thinking about upgrading.

Boxcar80 · 09-24-2019, 07:25 AM

Do you have to modify the stock BPV for the lower boost?

Boxcar80 · 10-11-2019, 07:18 AM

Its been awhile. Anything new with your build?

nvmylh · 11-07-2019, 05:37 PM

What happened to this thing??

pcampbell · 11-08-2019, 07:39 AM

Probably life! I’m sure he will be back

Man that'd be tough. Maybe if you could shave an inch off the throttle body and the IC.. you'd still have another inch to make up. Might be time to go with a custom one?

PART 3!!
I apologize for the delay.. I got lazy/unmotivated/busy/etc..

This one isn't too exciting, just making some changes to allow the turbo inlet fitment, and turbo oil feed plumbing.
