Original Post:

Today I thought I would get off the fence and start a build thread. I apologize, as I have never documented any of my mods previously so, I do not have many pictures. Before I get into my my current mods, I'd like to talk a little bit about my work space. I've heard a lot of people on this forum let a lack of space or a "shop" area detour them from performing moderate/significant modifications to their vehicles. I live in the second story of a duplex home in the city. For those in a similar environment, I wanted to let you know that it can be done.

This is my workspace:

It's basically a concrete pad where a garage once sat.

And this is my tool chest (also on the 2nd story):

Can you explain this with more detail. I plan to get this water outlet someday. Thx
Sure, the top vent shaft screws into the body of the outlet. It is designed to be sealed solely by an o-ring and a locking collar. I disassembled it, put Permatex water pump & thermostat sealant on the threads and replaced the o-ring.

Good lord that's bad...considerably worse than I'd expect.

A buddy of mine has an '88 5.0 that runs Megasquirt and runs E85 - we got it to a point where the fuel economy was nearly the same as running 93, but with considerably more power. It took a good bit of tweaking - finding different load points while on the freeway with me pulling fuel out until it'd start bucking, bumping it back up a number and then moving onto the next point. I think it typically got around 11-14 MPG depending on different factors (city/highway, how much WOT, etc).

There's still some adjustments to be made but, I don't expect fuel economy to get much better. Especially with the 180F Thermostat.

The 650cc injectors are putting a lot of E85 into the cylinders. I'm not even sure it would even run on 93 octane gasoline with those injectors.

Yeah, those are pretty good size. He was running 42 lb/hr injectors, but obviously in eight cylinders.

My Turbo Civic with a single cam D16 gets 32 miles per gallon using 93 with old school ev1 pte 650cc peak and hold Style injectors. City mileage is around 25mpg.

What kind of power are you making? I didn't see any Dyno graphs in the first couple pages and there are over 50 pages.
I'm not sure. No dyno pages yet. Still in the tuning process. It's on my agenda for the spring. Right now it's tuned for minimum boost pressure (1 Bar) for winter. ❄

I watched the video from Daves world and I just don't understand why these engines don't seem to make any power.... is it the cam grinds or the ports on the head? I wish I had a shop and time to be able to explore the generally poor power produced by these engines. There has to be a bottleneck somewhere. They make torque figures but not HP which suggests flow problems at the higher RPM ranges.

The OE style turbine housing is the bottleneck. The exit is about 1/2" in diameter going into the exhaust. GM's goal wasn't power. It was fuel economy. When the Cruze came out in 2011 in the U.S. it was one of the most fuel efficient vehicles available without going hybrid.

Oh yeah that'll do it for sure. I know that the cruze was built completely for fuel efficiency. That's why I was wondering where the bottlenecks are.

How is this build going ?
Right now it's just sitting on the back pad. I've had a nasty respirator infection for the last week. Not COVID.

Prior to getting sick, I had a custom brass V-band gasket made for the turbo. That fixed the exhaust leak and the intermittent stalling issue on deceleration. I got my custom emblem today but haven't opened it.

Do ya have any videos of it ?

I wanted to provide an update. I bought another round of custom tuning for $450. I think I'm up to $1,800 in tuning including the "stock period, the engine and V3 build, and now the G25-550 build. The Custom tuning is $1,350 of that. Including this round of revisions, it will be 25 revisions in total. :LOL:

It saves to be decisive, unlike myself. Keep that in mind kids!

On a positive note, With the G25-550 turned all the way down (14.7 psig), I'm already making more power than I was with my maxed out V3 setup at 24 psig. That being said, The new setup was $4,000 more expensive than my V3 setup.

Neeeyeah , neeeyeah.

That's why I'm on the look out for an appropriate sized S so I can spell out CURSE on my Cruze.

Just spent 6hrs in a u pull lot scoring a lightly used manual transmission... Throwing that aside with a slew of other parts I've probably spent close to 3000 and have yet to install any...
