That pic makes it look like it came from the factory boosted. Well done Aaron.

Agreed, that looks like a AFPR not a FMU. Are we high?

I don't know about you but a I have a Vault Zero here.

There do make adjustable FMU's but aren't all FMUs round, since they require the discs?

Wait till you see the completed down pipe, it will dispel all such illusions...

I'm not absolutely sure. That's what he told me, but it has no identifying markings on it, so???

Just up the pressure to like 60PSI or something, should get a few more cc's of fuel in there. Just make sure the fuel lines are on good.

Then he gets crap gas mileage and his idle AFR's go in the gutter...

I'm trying to get him to swap in some 370's he has and go with a MAF Bypass and base timing retard for tuning.

OMG

Please remove valve cover tube from cold pipe unless you plan on boosting the crap out of the valvetrain and block insides.....

Although funny to an onlooker it would surely make your entire budget and craftsmanship efforts moot.

Yeah, WD sorry, I'll buy you a beer if you're ever in CT.

Not true, My Enthalpy ecu I have been running at 75psi and Have perfect idle and cruise. I just don't know if it is safe. But in his situation, it might not matter, cause he has the RB waiting.

If you're running 75psi its because the tune sucks or you would be running rich, don't argue because thats fact. Rom tunes are either designed for high fuel pressure or they are designed around a 43.5 psi base fuel pressure. Increasing said fuel pressure WILL make the fuel map rich...period.

Update #2 - Project Success!

After a couple minor issues, the project has been deemed a success! The issues basically consisted of me neglecting to disconnect one of the pcv lines resulting in poor oil drainage characteristics in the turbo drain (think m4d smoking turbo) as well as some oil loss in other places. With that rectified everything seems to be pretty satisfactory. I didn't really have room for the wastegate actuator, so we just wired it shut. We're making max boost of 8 psi at approx 2700-2900 rpm. Here's some pics of everything.

Our sweet temp boost gauge



Apex-i GT exhaust (it came with the RB, so I figured I might as well put it on, it sounds great!).



The FMIC that also came with the RB.



Plumbing, cold pipe side.



REAL FMU installed in there.



Ign coil relocated to former air box location.



Side view of the turbo, showing the drain, supply etc.



The sweet downpipe mentioned before, kinda brutal but no leaks!



And finally, an over-all front view of the turbo.



That's really all there is to it. It took me about a week, working a few evenings and one Saturday. I'll be doing a realistic market value breakdown on everything shortly.

It's no rocket, but a 50-60% hp gain for $2-300 isn't bad.
