Hey everyone,

Alrighty, Im looking to achieve 470-500whp with E85. Yes, I have searched around and seen people with similar mods achieve 500whp, yet im making alot less, so not sure what else i need. Ive seen ix turbo 8s make the same hp as me and i have a bigger turbo so i dont know if it needs more aggressive cams, new tune, or if im just crazy and have the crave of hp stuck in my head
Car: 05 Evo 8 MR
Mods:
-Arp headstuds
-GSC S1 cams
-Greddy tic exhaust
-invidia downpipe
-Test pipe
-Hallman pro mbc
-Mishimoto radiator
-fp green (was an old school fp green, but sent back to fp to be converted to a 73hta, with MHI Housing)
-Ets 3.0" FMIC
-ETS licp and UICP
-FIC 1000cc injectors
-Walbro 255 fuel pump
-evo 9 BOV
-ETS intake
-converted to speed density
-omni 4 bar map sensor
-jmfab exhaust manifold (need to install)
-rebuilt head
-stock block w/ 126k

The car was tuned previously 370whp and 369wtq on 93 @26psi and 424 whp and 389 wtq on E85 @29psi.

Any help would be awesome, thanks! Sorry that this post might be repetitive

 

The turbo upgrade will have the airflow.

You'll need larger injectors (1200-1300cc) and a bigger fuel pump (walbro 450). I would think about an O2 housing upgrade. Otherwise it should do it.

 

Yea, I'm actually not sure that it has an o2 housing or not, so I'm going to check and if it doesnt, going with an map 3" or something rather than a dump
