liberty gt headers

[tony777]

Hi everyone,just bought a lib gt 04 auto, i found out they are twinscroll turbs and have equal length headers, can i just bolt on a set of wrx headers i want to get that rumble sound,i heard i will loose power would it be noticeable? would be highly regarded for some answers guys,cheers

I believe the answer would be no. If you search unequal headers there are a few posts on the subject saying why.

[tony777]

Hey, i did a search couldnt find anything,do you know if its possible like its still a ej20 engine i dont see why wrx header wouldnt bolt on,but im only guessing im sure some one will no for sure if you can just bolt a unequal header on.

are the manifolds different. ??

i think you may need to change the sump as well..

[tony777]

im assuming there the same basically as the wrx just being unequal length instead of equal! still awaiting peep that has done this change and comfirm it so i can go get sum headers!

[Jimmy S]

NO!

Twin scroll means it has a different layout turbo... so normal headers will not fit...

You may however be able to replace them with aftermarket un-equal length twin-scroll headers...

twin scroll means the turbo has 2 inlets in the exhaust housing(in a nutshell anyway)

thx for that mate good some one could clear that up for me,would you know any places that would sell wrx twinscroll uel headers?cheers

You will lose response.

Moz on here has done it, unequal length headers on his 2.0GT.

I have to say though. If you wanted the uneven note, why didn't you just buy a WRX?

hey, yeh well i just came outter 2 rexys one a 2002 sti, thought i wanted to go the classier stealth look with the lib but didnt know they where twinscroll turbs, anyways can you ask that guy where he got the headers from be great if ya could do that 4 me mate,thx

[tony777]

hey guys can some one tell me what moz's name is so i can look him up on the forums just want to ask him bout the headers,sorry just new to this site unsure who he is,thx 4 ur help guys

[tangcla]

I've linked him to the thread. Hopefully he'll make an appearance.

[tony777]

Ok,its not as simple as you mite think.
Firstly you need the same turbo that would go on a wrex,so that means you need a downpipe that bolts onto a rex turbo,then you need wrex headers and i think i changed the sump.
As far as power goes Mike got me an awesome turbo (zero sports)which was an upgrade for a gc8.I blow most rex's away.
Now mines an auto so tiny bit of lag at take of,but once spools up its very good,i suppose it realisticaly drives like a rex now and sounds like one.
You wont loose power,but you may loose a little responce as the twinscroll turbos spool quicker

Another thing ,you ecu will throw a hissy fit,so a tune is a must.
For me it was worth it as the engine was out and replaced with an sti short motor.
My advice would be to get a dpipe from mike,not 100% sure but perhaps the the dpipe from the 2.5 litre may fit,i just chopped the end of my avo dpipe and put the top of a rex one on,worked!!

[tony777]

aargghh i was hoping just a header mod to fit twinscroll anyhow, so that means for example a rex tdo4 turb will work and will the turbo mate up to the stock intercooler or will i need a wrx intercooler aswell, and i will def need a new tune or can u get away without it,cheers mate

You dont need diferent intercooler,but think you need a new uppipe too ,forgot.all these parts should be cheap and relatively easy to get ,check rex forums
You ecu prolly will learn,but if your going to that trouble,why wouldnt you tune
