help for engine build
 

Dear


I need to start building my engine

It's good now for this hp

But I need more power


The mod list :
Knok off greedy turbo kit
Gt2871r
Dw700cc injectors
Emusa 10psi external wastegate
255lph fuel pump
4bar map sensor
Oil catch can
Sti pcv valve
ecuTek tune





So now

What is the best CR?
What are the Forged pistons and connecting rods
good and Save my money for this turbo setup ..
Also do I have to change valve springs for this power??
Or do I have to change something else??


I can do the build (remove and reinstall)
My goal is 420whp - 450whp

I have 95octan on my area
And some places have 98ron



Any recommendations??

Right, but the questions you're asking may require a lot of time to answer then reanswer. Maybe someone can help but it's a lot of questions that require specifics and some.

I think there are only a couple options for rods and pistons out there. Carrillo, skunk2, Brian crower, and some others. AFAIK they are all upgrades to the oem and will allow a lot more power. But doing so puts more stress on everything else and may require upgrades elsewhere.

Look up maperformance engine rebuild. It's 3k and they add new pistons and rods and more. I will be doing that eventually.
