Most subie engine Nm and kW in here now

steptoe · Post by **steptoe** » Wed Jun 14, 2006 2:37 pm

I have renewed faith in EA82T after comparing TORQUE figures found in tune up spec book (could be errors)

EJ 22 16 valve 89 - 95 models
100 KW @ 6500
189Nm @ 4800

EJ 16 93 - 95 models
66KW @ 5600
128Nm @ 4000

EA81 79 - 84
4WD 9.2:1 comp ratio 59 kW @ 5200
135Nm @ 2400
FWD 9.0:1 comp ratio 60kW @ 5200
135Nm @ 2400

EJ 18 S
76KW @ 5600
147Nm @ 4400

EA82 carby
77KW @ 6000
142Nm TORQUE @ 4800

EA82 T
83KW @ 4800
181Nm TORQUE @ 2800

EJ20 DOHC 16 valves
85kW @5600
170Nm @4400

EJ20 E SOHC
92kW @ 5600
184Nm @ 3600

EJ20G DOHC Turbo
160kW @ 5600
290Nm @ 4000

EJ25D SOHC
115kW @ 5600
223Nm @ 3600

EJ25 DOHC 16 valve
115kW @ 5600 !
221Nm @ 4000 !

COMPARE LITRE TO LITRE between EA & EJ, not a noticeable torque increase between normal aspiration. KW yeah, but who drives at 6000 rpm (other than Tim)

until I experience reliability problems with 20 year old design I can't or won't comment

can see why EJ22 is nice choice as comparable to EA82T. In NSW EJ20 should comply with owner modified rego rules and no certificate from engineer needed ?

uh oh, what is this gonna start ?

The EJ 18 and the ea82 comparisons surprise me , I would have thought that the ej18 would have been much higher than the ea82 , I know mine used to beat Lseries and I had 27'' tyres on

Those EA82Ts do have good torque, they seem to just purr up big hills in 5th.

Anything on ej25's jono? (single cam not turbo)

Gee

i'd love to see some EJ20 specs.....

Suba · Post by **Suba** » Wed Jun 14, 2006 8:08 pm

EJ20-R DOHC 16V NA, AVCS
190ps/7100rpm 20kg.m/4400rpm

EJ20-i SOHC 16V NA (the first ULEV Subaru motor)
140ps/5600rpm 19kg.m/4400rpm

The EA engine isnt a 20 year old design it dates back to the late sixties, i like the figures but an easy gain in the EA82T is to add more boost (please renew headgaskets if you dont know how long they have been there, i get fed up with the bashers saying they are a shit motor because of failure of 20year old head gaskets and a healthy dose of boost) at 10psi you will get around 100kw and if you go to 12-14psi you will gain more and it will still be reliable, not to mention the added torque.

thanks suba

different rulers being used here kg/ metre ?

have to do at least head gaskets, can't even drive without pumping most water out of it in minutes ! oil leaks too so new gaskets and seals everywhere ...

i thought the ea82 carby was only about 66kw /85hp, ea82mpfi is about 90hp (vortex mpfi 90hp)

This could be a very interesting thread

There is no way that a carby EA82 has more power than an EJ18.

I thought the carby models were rated at 60kw, and the MPFI ones at 75kw?

The EA82 I have in my wagon now doesn't have that much more than the old EA81 did, and that EA81 had no compression! Plus my EA82 has a Weber.

Carby EA82 heads flow about the same amount as a head off a postie bike. There's no way a carby EA82 has anything on an EJ18.

EJ20R - is this the one I have? (BG5 Legacy GTB TT)

My L with Ej20 drives like a stock turbo ea. EA's are shit motors because of the cooling capacity, Dave is right though, anyone who calls them for shit because they failed headgaskets after upping the boost is a dick.

EA82's on 11psi, intercooled and 2.5" exhasut are a brilliant little package.

Only prob here is I need a cert to fit an ea82t, none to fit an EJ20 I know which is easier in the long run...

cooling capacity of motor itself or its stock radiators ?

Water flows through the heads too quick, take a look in the heads, coolant channels may as well not be there :P

steptoe · Post by **steptoe** » Mon Jun 19, 2006 8:36 pm

so has anyone tried to modify the flow rate to reduce it perhaps and what do you reckon could be/should be done (other than fit an EJxx ) ?

steptoe · Post by **steptoe** » Mon Jun 19, 2006 8:56 pm

Some of these figures seem to cause some concern, that maybe they are not correct (they are listed as DIN ?) must look to see what they credit the EA81 in the older versions some time

steptoe · Post by **steptoe** » Mon Jun 19, 2006 9:27 pm

has any1 picked the twin cam EJ20 got less figures than the SOHC ?

??

don't look at me ...until I check my sources

wildhorse · Post by **wildhorse** » Mon Jun 19, 2006 9:41 pm

this is just the start. next you might consider driveline drag betwen each...ie... readouts at the wheels.

joe_ritson · Post by **joe_ritson** » Tue Jun 20, 2006 7:49 am

Hey wildhorse, did you use XT6 hubs/custom drilled hubs/EJ driveline for those rims?
