I have a EJ20 that needs bored we are going to use the following to stroke during the process. My question is am I missing something. Also, what kind of HP would the proposed push with 16g turbo. Any input appreciated.

12200AA330 Stock STI Crank
Manley 620010C Pistons 93mm
Manley 14024 H-Beam Rods
Cosworth Gaskets
King CR4125XPG Rod Bearings
King MB5382XPG Main Bearings

Going in 02 WRX Wagon

 

over 9000

 

Thought a good quality 16g was ok for around 360ish bhp ?

 

Assume you are using a EJ257 crank as that's the normal route to stroke the capacity to 2.1 you will also need the appropriate rods.

 

Thanks for the help. We're looking at the vf34 IHI RHF5HB turbo.

 

I used standard length rods and stroker pistons in the few i've built.

 

different manuacturers achieve the extra stroke in differing ways so you need to ensure you have a "set" of matched pistons / rods
