Hello, I have a stock block Evo 8 2005, mods are in my signature. I am currently tuned on 93 pump gas on 25 pounds of boost on stock injectors. My question is if I put larger injectors what does everyone suggest for size of injectors and how much boost? I recently installed ARP headstuds and a new head gasket along with +1MM valves and valvesprings. What kind of power range will I be looking at? I don't see too many threads of cars with a setup like mine so that is why I posted a new thread. I made 360 on a mustang dyno with the current setup

At least 1000cc, you have E85 in your area, so I'm sure your considering it.

I live in North Carolina now unfortunately so e85 is about an hour or so away so I was going to do a dual map setup.

If you really are buying new injectors get at least 1000's as mentioned above even if you don't have e85 readily available. That way if it shows up you won't have to buy new injectors again. It sucks upgrading more than once. Ask me how I know....lol

Compressor efficiency peaks about 22-24 from what Robert told me when I got mine . He has pushed it way harder up I 28-30 I believe making gobs of torque. His graph is floating around the web somewhere ..

I have a hta 71 on the way and a 100% stock motor w/ bolt ons on 91 oct (currently ~320whp). My plan is some 1000cc injectors or slightly bigger and the same 24psi Ive been running on my VIII turbo.

Seems like the FIC 1050SPs are the bees knees at the moment. So Im leaning towards them.

That's how you do it realize that the best gain is not the greatest, but the one that actually runs the most efficient.

yeah I made 361 torque and like 360hp on a mustang dyno. I really want to turn it up as I am getting a daily driver and want to see what the hta71 can do before I upgrade to a complete t3 setup

I've done 30 on mine torque well into block killing territory . I'm back to wastegate now lol.

The sweet zone on 98 on these is ~24-25psi, any more I found intake temps sky rocketing.
On E85, 25-26psi.

maybe time to upgrade to a larger turbo then, it is crazy that stock injectors pair up well with this turbo

be careful not to grenade your motor if your still running oem rods.

boost spike of ~24/25 psi max.

torque (aka crack) kills oem rods....anything greater than 400ft/lbs dj #'s, may cause damage when below 4500rpm.

torque will make pretty windows, by spitting rods thru your block.

if you have drop-ins, then boost away. Have that bisch boost spike to ~28psi & settle down where it may.

if your going t3, why bother?

get a e85 walbro 4xx pump, cant remember exact model, buy some fic 2150cc injectors.

they drive nice & will support your dreams.....you'll just need to buy a dbl pumper when that time comes for your big turbo set-up.
