i can't, for the life of me, find any detailed specs on the 1995 J-spec WRX EJ20. I have found some good info on spec C RA and various other sti models on raven's blade, but not plain old WRX. Someone told me that the engine is a closed deck design same as ver 3 sti, but i don't know much else -rod ratio? compression ratio? turbo? dyno charts? transmission ratios? will it run without detonation on 93 octane fuel?



BTW There should be a sticky thread that lists information about all subaru engines on this website. So that is is all in one spot and easy to find. Seems like a common question.

 

yeah like the codes of the motor and what they went in and how much hp then can handle and if they are forged this or that

 

if you want something done...........

EJ20G = 2.0L turbo WRX engine used in early GC8 models
EJ20K = 2.0L turbo WRX STi engine used in Version III & IV models
EJ205 = 2.0L turbo WRX engine used in all 1999 to current WRX models
EJ207 = 2.0L turbo WRX STi engine used in all 1999 to current STi models
EJ255 = 2.5L turbo engine used in US Forester XT & Legacy 2.5L turbo models (+ some overseas)
EJ257 = 2.5L turbo engine used in US Impreza STi models

 

EJ20G "A type" WRX

HP/rpm: 236.64/6000
TQ/rpm: 225.06/5000
deck type: closed deck
displacement: 1994cc
bore: 92cm
stroke: 75cm
compression ratio: 8.5:1
piston type: cast aluminum
turbine type: MHI TD05
boost pressure: 11.6 psi

Apperently it makes that power on 100RON J-spec fuel which is equivalent to about 95.8PON US-spec fuel.

does anyone know how long the con rods are?

And a dyno chart would just be the berries if such a thing exists.

 

thanks for the info
