20G LT, 1st. day review.
I got the new 20G LT Turbo installed yesturday. First, I will comment about the turbo. By comparison, my stock 9.8 turbo is a much smaller unit. The 20G LT is a jewel. Once you got it in your hands, you can't stop to look at it. It is got a much biger compressor housing, a biger compressor wheel, then it is got a larger 10.5 hot side, and a much larger turbine wheel. Plus, the waste gate flapper is single and much improved. Add the porting option like I did, and get the upgraded 18 psi actuator, and you got a monster for a turbo.
Anyway, I installed the turbo and started the car for the morning work commute yesturday. Turned the boost controller off to verify the actuator was set properly. It was. I adjusted it a few turns at the time of install. With the controller off, I was geting 19.6 psi. Perfect. To make a long story short, I got to miss with it tonight. Tuned the mid-range as it was a bit leaner between 5000 and 6500 rpms. Made a few more logs, adjusted turbo gain and wastegate setting, and made sure I was at around 11.5 -11.6 A/Fs.
This Turbo pulls hard. At 23.4 psi, I am reading 2100 plus HZ on my SAFC at 68 percent throtle. I am posting a pic of the reading. The RPMs clime very fast. All clues that this unit is flowing much more air. I took my friend Manny for a ride tonight, and he was saying it was ridiculous. He drives a IX that has gone 12.05@114.67, and my car has gone 11.8@116. So it take a little to impress us. We both think this turbo made a big difference in my car. It is only been a day, but so far, so good! Here are a few pics of my VIII turbo next to the 20G LT. Both compressor and exhaust shots. A big tumps up for Buschur Racing and FP. In my opinion, great product that does what it was made for, stock spool up and much more top end. Pulls all the way to 8000. And, you better be looking, because it gets there quick. I used the stock manifold with a very nise and nasty port job. I will continue to update this thread on track and dyno runs in the next few weeks. I am thinking of dialing in the cams and crank and a may be also adding Meth injection. For sure, the 1st. few tests will be on C16 and 28 to 29 psi.

The turbo also feels like it spools like the stock one. I did confirm today on my E-01 that it does have a little more lag between 4000 and 5400 rpms. I made multiple logs and it will hit 20 psi by 3700, then goes up until 5500 and settles. So 20 psi by 37-3800, then 24.5 psi at 5500 and ends at 23.4 psi at 7500. Not bad at all. But the lag, if you want to call it that can only be seen in the graph. The pull starts early and goes up so fast there is no time to feel it.

What are your mods other than the 20g? Very nice review

Doesn't seem like the OP is running a reflash.
It appears to be an EBC, SAFC, cams and turboback exhaust. I'm guessing he has a Walbro fuel pump (if not, he should get one soon)
I would run a 20G LT with a custom reflash and bigger injectors, but that's just me.
