Still go in tank, and factory will be fine for 300-350hp. Or go with a walbro 450, they're cheaper and flow more, and can be done in tank, which most fuel cells allow for. As for AN line, it doesn't really matter. The stock tiny fuel rail and lines, without full return, flow more than enough for 350hp And I do have my EGR deleted, the custom plate is for the coolant pipe because I don't use an eclipse intake manifold. The EGR blockoff is done by drilling and tapping the head, and driving a plug into it www.amazon.com/Walbro-F90000267-450-fuel-pump/dp/B0085ECSIU here's an example on price. |

I know staying with stock tank and using drop in would be the cheapest way. But i'm going to be replacing everything with the cell, fuel cells with drop in pumps is an Idea I have pondered though. But I would need to hook the vent/rollover valve back to the evap canister so I don't throw evap codes. Either way I want to go with return style fuel system.

There's got to be a way to cheat the evap system. Perhaps even just capping it off, or leaving both ends to atmosphere. If you find something that works on an evo to do it, it'll work on the Eclipse. Same EVAP system essentially. The parts can be interchanged aside from fitment (I used an evo evap solenoid for example with the manifold change)

I have to ask Michael if he can cheat the evap system, read up today that our pump assemblies hold the tank pressure sensor. The problem I always run into is doing a modification and keeping the car street legal. Luckily here in Jersey they only do emissions, and all they check for that is plug into the OBD2. But i'm pretty sure if I unplug that tank pressure sensor it will throw a code.

So what if you leave it plugged in and it only sees atmospheric pressure ever? Or you could add a vacuum line to it with a check valve to prevent boost maybe. Theres got to be a trick

Quick searching so far on the internet shows most models being shut off via ecm tuning. But emissions testing needs the ecu monitor to show ready when checked. I'm gonna send a message to Michael and see if he's had any luck on the evap side. If not than I might have no other choice but to do a drop in pump and stick with the returnless for a bit longer.

You can do full return with a drop in pump. I've got a double pumper walbro 525 setup with full return. You could literally just drill a return hole into the tank

Yeah, but if the hole you drill ends up opening just a hair that sensor is going to throw a code. Messaging with Michael now, says I should be able to reuse the sensor off the assembly. Talking with him I realized I can have a cell made to house the stock pump assembly and just have a return plumbed into the cell. I'm gonna have to pull the pump assembly this weekend to see how that sensor is mounted, Michael says I should be able to reuse the sensor with a cell. Just trying to find out if that sensor will fault due to being in a smaller tank.

I can't imagine tank size would any any impact. The tank houses liquids, which makes it a variable airspace volume as is

After talking with Michael last night, i'm going to give it a shot with moving the sensor over and plugging my rollover/vent into the existing evap system. If it doesn't work i'll just pay Michael to shut it off. Getting a flux core welder after the new year, so i'll be practicing on building an undermount for the trunk area to hold the cell and battery. If that works i'll be shopping for a bottom mount turbo manifold.

Or for the time being I can drop a DW65C into the tank and upgrade injectors, but all I can find for those "pinks" is reconditioned or chinese knock offs.

You could also stay stock pump in the stock tank and just upgrade injectors. I don't think a DW65 is needed over stock, seeing as stock already moves enough fuel for 400whp, maybe even more. At 16psi I wasn't leaning out on the stock pump, and that's higher than your power goal

Makes me wonder if Mitsubishi was in fact planning on a GSX platform for our cars, didn't think the stock pump had that much power. So the only crippling factor is the actual injectors. Technically speaking what injector would work with our cars and up to 350hp? Found some subaru high impedence, but I believe they were only 425cc. Have reman stocks in now and they are annoyingly loud.

Subaru makes a 565cc as well you can pick up cheap. I got mine for $100, used, off the NASIOC forums. They are commonly sold there. In theory their limit is about 450hp @60psi. I'm gonna be looking for some larger injectors next year, as I think I'll be able to pull off more power than they can run on my current turbo.
And I'm almost certain they planned for an AWD turbo setup. ALL the parts needed can be acquired from the factory, all the parts fit, everything lines up. V6 looks like it was an afterthought, but turbo 4 cylinder works perfect.
From info I found on 4G69 testing, it was supposed to have become a turbo engine at some point, but we got stuck with the economy version due to the economic global collapse in the automotive market about the time this car was to be released. The Outlander was the test bed for the 4G69.
But here are some facts. It has the best PCV of any 4G motor (has extra vents in the block and head, very important on a turbo motor). Lightest rotating mass. Strongest crankshaft. Tied for largest displacement. Highest flowing head. Gallant Ralliart pistons @0.5mm over would have fit, which Mitsubishi had previously produced, which were also forged. 4G63 rods fit perfectly, also forged. The recipe was there. The kitchen just couldn't change the menu when the customers were asking for liver and onions, not filet mignon.

I think the 565cc are the pink ones. Guess I could go the used route and get them cleaned.
