I have looked around and searched a bit and I think I have my mind made up as far as which turbo I should go with (Evo 9 vs Evo 8 10.5 Hotside).
03 Evo
Current Mod List:
HKS Hi-Power Turbo Back (Test Pipe)
Megan 02
Megan Exhaust Manifold
Injen Intake
Injen Intercooler pipes
Greddy Intercooler
HKS BOV (Just bought a dual vent turbosmart to recirc)
ACT clutch
Awaiting Install:
10.5 Hotside, MBC, Walbro Fuel Pump

I was wondering what size injectors should I get and also I know the megan Exhaust Mani is **** but would it be better to just port a stock one I have? I was also planning on porting the hotside, 02 to make it all match. My goal is to hit 330-350whp on 91 without cams. Would this be easier to achieve with the 10.5 8 turbo or a Evo 9 turbo? Also, any suggestions on more parts to add? Thanks in Advance.

 

you should be able to make your goal with that you have now more or less, at least the 330whp for sure

 

get stock mani ported, and get 9 turbo I think 330 on what dyno if Mustang it would be harder because MD read lower than DJ.

I have an evo 9 and run E85 with cams stock intercooler 370hp 365tq and I used to ran 91 with cams, HKS intake, o2 housing 3'turbo back, and fuel pump I made 328hp 320tq on Mustang Dyno

IDK just my opinion, So I recommend to run E85 is the way to go there is E85 station in El cajon !

 

I am trying to keep it simple when I don't have time to get E85. I will have 2 maps eventually but I want to just mess with 91 for now. I live in Imperial Beach, El Cajon is a drive I don 't wanna make every 3 days lol.

What size injectors should I run?
Why is the 9 beneficial over the 8 with a 10.5?

 

700/800cc should be fine. Its not like your gonna be running them on 100% cycle.

The 9 turbo has a bigger coldside than the 8 so yea gains over a 10.5 8 turbo will be minimal but gains none the less

Just stick with the 8 10.5 hotside.

 

get the evo 9 turbo because you can always send it in when your ready for a bbk upgrade or fp series upgrade

 

Get a IX turbo. Your stock injectors should be good.

 

Why no cams?

 

You probably won't make 330 on a Mustang on the stock turbo w/91. I barely made 330 with the OG FP green on my IX

 

I don't want to mess with cams at the moment, I want a simple set-up for now until I get a bigger turbo/max out the 8.5 turbo. I will do a E-85 tune a couple months after my 91 tune. I will have two maps but for now I want to max out a 91 without cams. Any other parts you guys think I need?
