Default ej207 power!

not alot of info out their about the ej207.
so i decided to share my experience with my ej207.

04 wrx chassi
version 7 ej207 power plant functional avcs
twin scroll blouch 1.5 xtr turbo
twin scroll equal length jdm headers
full tommy kaira turbo back exhaust
850cc dw injectors
gm front mount intercooler
grimmspeed 3 port bcs
hks recir bov
grimmspeed aos
one step colder spark plugs
costum 76mm intake
93 octane
etuned by Clark Turner

( soon to run water/meth injection kit after winter )


i have put almost 20,000 kms on this engine was running a 7cm fp green but i didnt like the turbo response very much decided to go with something ball bearing seemed like the right thing to do for a smaller displacment engine.
you can start to feel the trq comming on around 3500 at 4000....4100 is when it really kicks you to your back seat.
i dont have a dyno graph or anything due to the car was etuned but feels like im at around 330...340 whp running 20 psi.
feel as strong as the fp green but a bit better response then the fp green.
i have not had the pleasure of taking it to the track yet but stock set up i was doing 12.9 on 1/4 mile im expecting to hit low 12's fingers crossed.
once water meth installed o hope to reach close to 400whp.
the closest races i have had was with a 06 sti with a 20g beat him by 1 car
and a 03 porsche carrera 4s i beat by 2 ...3 cars.
im happy with the power it makes just wished i could get a little more low end power...
once winter is over i will dyno the car with and without meth inkection so you can see the diffrence.
future plans with my set up maybe swapping the 2.0 with a 2.5
unless i can find an alternative to getting a little more low end power.

Why not try a 2.1 stroker?

I currently have the blouch 1.5xt-r twinscroll being assembled, stock inlet size but ceramic coated and going on a ej257 with forged pistons. Running the ID 1300 sidefeed conversion kit with billet rails and ID lines.

Honestly man there's no replacement for displacement and mainly the only way you will find more low end power is with a 2.5 block. The 207 is an amazing engine but makes it's magic happen in the mid-top end range. When my bugeye gets finished and tuned Ill post up a dyno sheet for the record.
