So frustrating.
Speaking of frustrating, I just realized that the timing tool kit they sent was for the wrong engine. I’ll be getting the correct one from amazon in a day or two I hope.

Ugh! Amazon sent me the wrong tool kit again. I think the problem is that the company seems to have labeled a run of 1.6 Ford timing tool kits as 1.4 GM kits. Amazon support is of course clueless, and the company is Chinese without much info on how to get in touch with someone. I bit the bullet and bought the vastly more expensive genuine GM tool kit from Freedom Racing where I got my other two GM tools for the turbo swap. 6/4 delivery.
The rest of the replacement parts for the turbo swap are supposedly going out today. They had to wait on the TTY manifold nuts to come in. Sloooooowly working in the right direction.

The GTX tune has some hiccups and I’ve sent a few logs in for it. I blended some E85 into my tank of 93 yesterday for an E30 mix and that helped a ton. There’s still a slight surge most of the time in the 5500-6000 range. Other than that it’s feeling very nice.
I can’t really feel any loss of response compared to the stock turbo and the pull in the top end is night and day different. I believe my ported throttle body and my VTA BOV are causing some of the issues, so I’m hoping those can be resolved with some tune adjustments. I need to make time to get the valve springs installed so that it’ll pull strongly all the way to 7K. I’m on a 23psi file for now, but once BNR has the tune straight I’m planning to work up to 26psi or more if the turbo has it in it. I’ll keep it to <30psi no matter what though.

At first I wasn’t sold on the ROI, but the more I drove the more I appreciated it. The feel below ~4500 is very similar to stock, but that feeling you get with the stock turbo where you get planted back in the seat for about 1000RPM followed by a huge let down…never happens. It pulls well all the way to 6000+ even on the stock valve springs. Keeping in mind that I still have the valve springs and at least 3psi more to look forward to makes it even better. Holding 26+ all the way to 7K will make it all well worth it.

These little motors really are amazing. I found one locally with an auto trans for 300 bucks and I'm just trying to talk myself out if buying it lol. Also pondering a trax AWD swap....who knows. I'm out if work for July though so I cant do anything too rash.

AWD would be so cool! I wonder how much fab the body would need to accommodate that.

Well the cruze sonic and trax are all based on the gamma 2 design so there are a big pile of similarities but so far I'm not 100% sure....I haven't had a chance to get a good look at the underbelly of a trax yet. But this transmission is out of an AWD so.....ugh. I dunno if I'm gonna be able to say no to this one

In these cars with stock frame style turbos, the drive pressure (near 3-1 on the top end) causes the exhaust side to valve float before this intake does. This is why Walker for example can run 30ish psi to 7k on stock springs. His drive pressure is closer to 1-1 due to the turbo size and tubular manifold.
That same drive pressure is hell on turbo thrust bearings. and these stock frame bearings, even when upgraded, are pathetically tiny compared to almost any other JB turbo. roughly a dime size compared to a standard t3 turbo thrust bearing being the size of a silver dollar.
How hard you push it is obviously between you and jerry, but i'd hate to see you throw your money in the trash for the sake of chasing some psi number.
He seems to think that 26psi is safe and I don’t track the car. I think with my limited use I’ll be fine. I’m not necessarily wanting a specific boost number either. I’m going to get the 23psi setup finished and add to it slowly. If I can’t really feel any difference on the street, I’ll stay at 23.
