I know a lot of people have been wanting to see this and I finally made it happen. Unfortunately my oil pressure has dropped ~8-10 psi from when I first build the motor and I'm getting higher iron content (only iron) on my regular oil analysis, I'm hopping is just the oil pump getting worn out.
The reason I say this is because I did not push the car to hard (well, as soft as you could be with this kind of power on a 4 banger lol) and I could still run more boost and timing as this is only 16* up top.
Enough of the excuses!
These are 3rd and 4th gear:
And since some people are curios about this turbo VS a 9180 I'll throw these up for comparison:
3rd and 4th gears, Red is 9180:
3rd:
4th:
Things to note on the runs:
9180- .92 IWG, 37psi, 108K max turbo speed, only lasted ~600 miles.
9174- 1.45 EWG, 42psi, ~115K max turbo speed, has taken a beating LOL.
I'm going to drop the oil pan to have a look and replace the pump, chains, guides and also check the valve lash. Hopefully it all checks out OK and if so then I'm doing a 3.5" turboback exhaust and back to the dyno!. At this point I feel the engine really needs a head and more cam, hopefully all is good in the motor and I'll throw in a CNC head with some Kelford C's or Tomei 280's Hahaha!
I would love to be able to reliably run the 9180 on Kill as is obvious that psi for psi it would make more power with the same configuration as the 9174, but that's simply not reality and the 9174 has in fact taken a real beating and just keeps on chugging.
Ok one more comparison, now with the 8374!
This is a 8374 .92AR IWG, only holds 32-33psi up top at 100%WGDC. No turbo speed data but the turbo blew up about 4k miles later due to over speed.
Great results! You are realy bad boy ✌️��
P.S. Tomei 280's is bad idea to install it to 2.0 engine . Reason in exhaust cam , overlap is to big to 280cfm cilynder head ))) I have expirience with this cams on 2.0 engine and efr7670 turbo.. The car has a bad moving before the spool and low hp and tq. We install to that car 270's and all was ok. 280's tomei is good for a stroker engine.
It seems like the 9174 will make more power simply because it can run higher shaft speeds then the 9180?
These EFRs seem great for a street car not pushing the turbo hard due to the powerband strengths. Start trying to max out the turbo though and they seem to fall apart?
So you've destroyed two out of three EFR turbos? What was the failure mode of that 9180 that only lasted 600 miles?
Overspeed.

This is how I see them too. They are awesome for a street or track car that is not meant to be run on kill because of the huge powerband and transient response benefits.
But if you overspeed the turbo, the turbine wheel will fail. Just a tradeoff of the turbine material.
Yep, that 8374 looks to be a lot of fun. The 9174 with a .92 has got me thinking a little though because of that PZ Tuning Honda K-series. They made 660 at 18 psi with a pretty nice power band too. Not sure how it would stack up on the 4G63...
