Ok so I have a 03 Evo 8 the mods I have now are

Walbro 255
BC 272 cams
Ams IC
Upic
Mishimoto rad
1150 FIC Injectors

I ordered the sheepeybuilt kit with the precision 6266 bb turbo will come with the mainifold downpipe 45mm turbosmart wastgate and feed lines and also a LICP

What other mods should go along with this kit to run safety its pretty much the stock engine previous owner said it has a stage 2 clutch i have no idea which clutch lol though

 

I forgot I have an injen intake as well

 

So you got a $4.000 turbo kit that's capable of making 730 hp and you don't know what you need to be able to use it? Good luck. You need a ENTIRE build to get any potential out of it. The only thing you can reuse is your radiator and maybe your fmic depending on what one it is.

 

lol.

Clutch, intercooler, intercooler piping, boost controller, tune. You'll need bigger and injectors and fuel pump if you're going to run E85. And make sure you take it to a good tuner that is fimiliar with tuning stock block big turbo Evo's to keep the torque in check...

 

It's a waste of the nice BB turbo if you don't have a built block.

 

It is a waste all the way around if it’s not built around that turbo. I hope the OP does not end up like so many others here that run a 62+mm turbo at 15 psi and never see what you paid for.
