hey guys just wondering wheather this will be worth the money

atm i have a ej20-g jdm turbo engine in my 1992 liberty GX with mod plates for the conversion
but im chaseing more power best bang for the buck been weighing up puting forgies in it but seems cheaper and a better idea to just drop a ej207 in it

as they are factory forged

if i was to do this i would also be changeing the ej207 heads and puting sti heads in
and useing as much as possible off the ej20 for the conversion

just wondering how clean of a swap will it be
what will i need to change

and would it be worth it or just keeping the ej20 and rebuilding it ?
will only be a week end car and im chaseing for good straight line runs for the time being

ej20 in it atm has a few small mods like air intake/4x bosh coils/irridium plugs/jdm ecu/blitz sbc sequentiel boost controller /exhuast/ also have yet to put my fmic in engine has done around 140 000 km's

or is there a better option for money for the power ?

All but the very first EJ207s (v6 STi) had AVCS, so you can expect to be doing a fair amount of re-wiring if you plan on using the 207 heads.

Not AUDM. However, the castings are ready to accept AVCS.
To the OP, this is not an easy plug and play exercise if are changing heads. With that comes intake manifold, injectors, rails, timing gear and a host of wiring. Maybe even cross over pipe.
What is the aim of this build.

Is another 2 litre engine going to do that much more? I reckon for the hassle try to find an EJ257..

Really? When did AUDM make the change?

[aekOne]

wasn't avcs first available in the jdm v7 and audm for v8?

hi,

boost you ej20g up till it breaks. they can take a hell of a beating.

sounds like a plan would be a good experiment to see what i could push out on standard internals with 140 000 on the engine.
not expecting it to last long. if she blows even more the reason for engine change or rebuild

hmm wonder how standard internals would do up around 20psi. thinking it would handle it for a bit as long as im not boosting it everywhere
but would be intressting to see how long it would last.

alex: looks like new injectors / ecu / fuel pump . and front mount install ?

its on 12.5psi atm need new AFM sensor its doing the idle 900 to 1100 up and down soon as its warmed up

read they are capable of handleing 20psi but dont last long

Pretty close then. Still, the wiring between an ej20g and ej207 is going to be just a wee bit different.

lol thats the part of the conversion i was dreading.

was really hopeing the same harness would fit but apparently not
starting to swing towards just rebuilding the ej20 and going all out on it instead

but still tossing up what to do will be getting pulled off the road in 6 to 7 months time and going in car port
for 2 years for a complete rebuild from the ground up

how much i spend on it will be most likely around the 20k to 30k aiming for around the 26k mark so after that i should have something fairly decent built

p.s able to do this becuase i dont have a miss's lmfao

you can only have one or the other ive worked out cuase they both cost to much money if you try and have both you will go bankrupt

If you're JDM as f*ck....


that'd make me JDM as sexeverywhichwaywithathousandvirgins?

you think boost gets you laid? lol





to add constructively, swap short block. keep heads. reco them. slap motor back together.

so bolt your heads to a 207 shortblock.


the effort/time/money to swap to AVCS won't be worth it in your instance.

hey i was just fiting in with the crowd you know every ricer/honda owners (think that)
i mean every honda you see has the JDM as F#CK sticker and they all think there weak lil turbo's get them laid lmao

although i do know a chick that does get off over the sound of boost

yeah good point going to be doing the mojority of the build my self going to be a whole new experiance always had N/A engines and never had a suby before
they seem simple enough

reco the heads and a port a polish to open her up a bit more better valve springs
heres a question for you is the cam worth doing ? cuase the way i see it its not becuase of the forced induction am i wrong? i believe i would only see mild power gains from doing so
so would be a waste of 1200 dollers


also what are the standard intake manifolds like they good for the flow or would you reccommend an improved upgrade cuase by the looks of the standard i cant see it being very resricted but what i do see is a bad planum set up and wondering wheather there bad for teh higher power and leaning out on a cylinder


excuse the bad grammer sorry i dont know how to spell correctly

[Scuba-Roo]

Pretty sure the manifold flow alright, unless your going for massive massive power. Parallel fuel rails and a decent ecu and tune should stop any leaning out

[Alex]

For the money, you're better off getting a set of MY97 heads, and recoing those. They're the last of the heads where your intake manifold is still possible to bolt onto, and the design of the head is designed better, for greater flow.


Don't port and polish.


I repeat.

Don't.

You'll add lag.

P&P is only good if you're chasing north of 300kw.

Cams again, are for serious builds. 207 isn't that serious.

Intake plenum is good for 400kw + and is not a restriction.

Fuel pump/Turbo selection/gearbox/up pipe/dump pipe/exhaust/fuel rails/FPR/FMIC/CAI/Injectors/boost levels/ECU would be your next lot of restrictions... in that order (slightly)

Honduhs are for retards. Most wouldn't know what the heck JDM is. I'm sorry to say, orange indicators isn't JDM, y0.

what ecu do you recommend ? been looking at the fc power but thinking its a bit over the top for witch i will require

or should i just piggy back it ?heard its not as good and can be risky
