FYI - the 1998 STI engine in my single turbo legacy will handle 17-18 PSI stock. Version 7 WRX STI (blue one in the drag video) has factory tuneable ECUs so you can up the boost AND fueling, dont know the limit.. i sure as hang wouldnt attempt anything like that without a dyno.
(of course i am referring to JDM spec engines here),

yea i know i cant do 20 with the stockers. they blow around 400 hp

I pushed my EJ20R to 18psi

SpecBamf41 04-29-2012 05:34 PM

true. and it was open deck and all you did was blow the head casket

TexasLegacy2.5GT 04-29-2012 09:58 PM

^^^ I think Furman had the EJ20R in that built BD...

broknindarkagain 04-29-2012 10:41 PM

It was an EJ20R...and it was open deck as well.

Head gaskets failed due to the GT3076R turbo that was on it before.

TexasLegacy2.5GT 04-30-2012 07:39 AM

^^^Furman, what the name of the JDM Boxer 2 stage turbo and is it open deck? Is that boxer worth building?

broknindarkagain 04-30-2012 10:35 PM

The EJ20R.

It depends on your power goals. Under 400 its fine.

Headgaskets failed on mine because they were crappy stock gaskets. They had the same problem that the EJ25D head gaskets have

SpecBamf41 04-30-2012 10:41 PM

what do you think i can do safely broke?

phase 2 open deck 2.5 with my homemade close deck.
sti crank,rods and pistons. if could find some used forged pistons i would take them.

broknindarkagain 04-30-2012 10:46 PM

uh....who knows. I don't think your home made closed deck is very reliable to be honest with you. I wouldn't push it more then 4 or 5 psi
