I never thought about that but since you mentioned it im going probably for the 450 pump, also from my research I find that Mishimoto is a common name brand which is why I was going for it, correct me if im wrong tho

As long as you have a free-flowing exhaust, injectors + pump, piping+ intercooler, a light cam, and a good tune (basic bolt ons), you should easily be able to make 400whp on e85 with a stock 9 turbo. If you want to make 400whp on pump, gonna have to get a bigger turbo.

My mods are:

- GSC S1 cams
- 73hta fp green turbo w ported mhi hotside
- 3" ETS FMIC
- ETS UICP & LICP
- ETS INTAKE
- 255 walbro
- 1000cc FIC injectors
- JMFab exhaust manifold
- MAP o2 housing
- Greddy TIC catback
- Test pipe
- grimmspeed ebcs
- spoolinup COP
- Omni 4 bar map sensor
I woudlve ran e85 if it was closer to me since I dont really daily drive the evo, but the part list is helpful thanks

Whats the difference in the Forced Performance "FP54 Green" vs. Forced Performance "GREEN 73HTZ"? theres so many drop down options at extremepsi.

I'm FBO stock block and dyno at 398whp with e85 on a mustang 10 years ago. Now looking to upgrade turbo.

They share the same compressor wheel but the FP54 has a smaller turbine wheel and will spool a little quicker vs the Green. FP54 = 60.8mm in / 54mm ex vs Green = 67.3mm in / 58.8mm ex

I never post but my setup is pretty close to what people are saying. I have an evo that is decently modified. My mods close to what people are saying. It makes 425whp/ 340 tq. but it does it using 92~93 pump gas also on lower boost. 24.4 - 24.5 psi. The mods I do have are fairly easy to get.

gsc s2 cams + springs and retainers
fp green 73hta
fp exhaust manifold
map o2 dump
ets 3.5 fmic + 2.5 ic piping
950 fic fuel injectors
3' dp
3.5 cat back
aem truboost
act hdss clutch
walbro 255 fuel pump

There might be more but these are my performance. Hope this helps. I have been told this setup with e85 will make 550 whp easy.
