I looked at the specs for the FP54 vs the AGT 52. IMO the AGT 52 is not a comparable turbo to the FP54. However the 52mm turbo is super cheap. I am not sure if there are any turbos that compare with that value.
deylag has the right idea, all 3 turbos listed are fairly different.
I have personally run the Green and loved that turbo. It had slightly more lag than the factory unit but pulled harder in the higher RPM range.
I would lean green just for the larger turbine wheel to try and get it to hang on as long as possible out top.
One thing I will warn you about is if you stay with the MHI exhaust housing, no matter what you pick, there will likely be some dropoff at higher RPMs as that housing chokes it out. I have run into this on both my green and red when tuned on kill.
Is the MHI-18k different from other stock frame aftermarket turbos?
I honestly havent looked into it.
Can they be used with stock fueling and boost control?
Correct, they can be used with stock fueling and boost control to pass smog. For all else, I would run a 3 port bcs and bigger injectors/fuel pump.
It's a Mitsubishi turbo that has stumped state refs(state ref service manual drawings are incorrect anyway), uses oem oil feed lines, and can make 500+hp on E85 while spooling almost as fast as the stock turbo. On my 2.3l it spools faster than stock and makes tons of midrange power, which is what I was after.
Have to ask yourself what makes these cars fun around town. Response and low end torque.
I'd go with an FP green MHI 10.5 housing for an evo 8. Or an FP red MHI 10.5 housing for a 9. They come up really well and the oiling issues are solved on the 2020+ BB units. They come with a premium price but deliver power and response.
This is my stock cam evo 9 engine on the red with E85. It can make more at lower rpm's but you want to stay under 400lb ft on a stock engine below 4000 or so. The red /evo 9 combination is as small as I would ever consider for a street car unless you auto x. Then a 18K or HTA71 would be ideal with that.
Too small of a turbo doesn't drive that well and chokes the engine at high rpm.I feel the green/red are OEM + upgrades. Both will make 550whp+ up top or be torque monster on a built engine. My 2.2 makes 500lb ft at 4000 If need be.
This is a Boost lab 25G on a stock 9 . What powerband would you rather have?
Looking to keep good spool but want something that pulls a little better in higher rpm compared to my 71hta.
I was looking at these 3.
Fp Green
Fp54 Green
AGT 52mm
The AGT is the cheapest and the owner states is similar to the fp54 but slightly better spool. Most of the threads on the fp54 are from 2016.
What are yall's thoughts? 95% street car, occasional track days.
Mods so far:
Ets upper and lower pipe with 3.5 wide core
ID 1050s
walbro 255
Grimspeed EBC
02 housing with 3" test pipe and cat back
71hta
GSC S2s, ID 1300s and an Artec exhaus manifold will be thrown in with whichever new turbo is picked.
Too many people pushing that AGT turbo lol, it’s a cheap turbo with various parts from China to Taiwan and he has the nerve to price it up there with forced performance.

Yea the FP red has more midrange and faster spool up compared to the BL 25g. The 25g has a touch more up top which would make it better for the strip.
No one wants to build a street turbo setup now. Everyone is thinking they need more power but all they do is build a laggy setup.

I mean if you put it that way most aftermarket MHI turbos can do that as well. The 18k's advantage being its a new MHI turbo that bolts up like stock. Do you run an anti surge cover with your 18K?

Your not the 1st person thats recommended the red to me, since I have a 9. Definately considering it now. Just always thought it would be too laggy for a 95% street and occasional track day car.

That's what I am trying to figure out. I initially went with the 71hta and it was absolutely fun driving every day. Instant power. But I understand it dies up top.
Which made me want to go with the green next. But a few recommendations to go red have come up.

71hta and AGT 52mm will be very similar with the 52 having better top end from the slightly larger compressor wheel. The fp54 is the next step up and is nearly identical to the AGT 55mm with the 55 having better top end from a slightly larger compressor wheel. The fp54 and AGT 55 will both do 400whp+ on pump 93 easily and hit 20psi by 3.5k-3.8k rpm

The prices are not even comparable, what are you on?
What was your experience on spool difference between the green and red?
So I never got to run them back to back on the same engine setup. I moved to the red after I built a high compression 2.0 and changed cams.
The green on the stock motor was great, spooled real quick and was as close to a stock turbo that makes 500+ on e as you can get. It was a great setup.
On the built motor with the changed cams, the red I have basically spools exactly the same as the green on my stock motor did.
I will second what Abacus stated, the red is a really solid turbo on the 9 with the variable timing improving spool. It also offers more up top than the green and considering that with either you will have to limit torque on the stock bottom end, that would probably be my pick.
