Okay so im kinda stuck currently. Im looking for more hp/tq outta my car. Currently I have full AMS Bolt ons, 1100cc injectors, fuel pump, e85, tune, exedy twin disk and flywheel (hopefully not forgetting anything) . What would be the most beneficial upgrade to get next?

 

turbo?

 

Nitrous??

 

Turbo, check out the FP line maybe?

 

Is it safe to run a bigger turbo on stock internals though? and Ive read multiple places that most evo owners dont run nitrous, if someone would tell me why that is itd be appreciated!

 

I wouldn't recommend running nitrous unless you have a fully built motor. Yes you can run a bigger turbo on stock internals, however you may not see the gains you want until you build at least the top end. I know a fellow evo owner who is running FP black, with nothing but bolt ons, but is only putting down about 370hp. His tuner recommended he not run higher boost or he'd melt the internals.

 

Yeah I'm already currently at 385/385 on full
Bolt ons and e85 so ill wait till I build my internals. Would getting an exhaust manifold be okay to get safely?

 

ef4 turbo

 

The gains would be minimal with an upgraded exhaust manifold with the stock turbo.
