12 GSR with 40k miles. Just purchased Clutchmasters s4 sprung 6 puck with master cylinder upgrade kit and 11lb fly. Current mods: ETS: intake, uicp, licp GrimmSpeed EBC, MAP mani, o2 dump, testpipe, AgencyPower dual TI. Dynoed and tuned at english racing making 359.8whp@ 29psi. (Just before i added the mani and DP). Estimated 370ish with english eTune. Thinking about doing some fuel upgrades and wanted E85 or higher octane fuel (95) just for some autoX shenanigans but ive never messed with a fuel system before and wanted have a few opinions. What would i need to make it happen?

 

1000cc injectors and a Wally 450

 

Im thinking ID 1000's and english reccomended the aznu 320lph

 

Get ID1300s and either a wally 450 or DW300. I'd personally recommend getting a flex fuel sensor too which is what I've just done and it's great. Once you've done these mods you'll be wanting at least an Mhi-18k which is why I suggested getting the 1300s so you won't need new injectors again.

 

That wally 450 should be too much

 

I'll say ID1300's and a walbro 450. As soon as ur done tuning it'll feel slow in 3 weeks and you'll want some bigger turbo action.

 

agree, just save up and wait a bit and get a bigger turbo along with injector and pump. That will keep the mod bug off of you for at least a year or so haha.

 

I'd do suspension and better tires

 

if you have E-85 accessible I would go with FIC 1100 and DW300c. Also you could add cams to the car

if E-85 isn't around I would go with an aquamist kit
