Turbos Turbos Turbos
Posted 16 March 2005 - 01:13 AM
On my way to acquiring an older turbo'ed Sube and was wondering if I could get some info out of you modding cracks. I hear a lot about people slapping WRX turbos onto their EA82s and rumors about other people doing the same with Volvo and other manufacturer's units. So whats all that about, how hard is it to upgrade to a cooler turbo, how can I tune my existing one to achieve more of this so-called boost everyone is talking about :cool: and how does one make sure that overpressure doesnt occur and disintegrate the engine?

popular turbo swaps for the EA82 are the VF11 ( stock usdm leagacy turbo) and the TD04 ( stock usdm 02-05 wrx turbo)
the vf11 will bolt to a stock EA82 up-pipe, you will need a new downpipe however, any any td04 wrx DP will work..you will need to modifiy the oil and/or coolant lines and intake pipes.i do not have "details" as i have not startd my swap yet..
the TD04 will need to have its flange welded to your up-pipe and will need a wrx downpipe...lines will need to be slightly modified and new air pipes made..
hope that helps

Get rid of your cats[u can use 1 large performance cat] and use a larger DP + exhaust this'll free up just a wee bit more than 2-3 hp [like 20 hp] and the throtle response will be unreal. A good filter with a cold air intake or chopped out air box helps plenty too. If you have some dollars you could go with a different turbo but unless you do it properly it's a waste of money and time IMO.

Call Folger SUBARU, talk to Mike Melton in Parts about them. They are the only ones in the USA that have the READY TO SHIP right this second.

had a down pipe made by them. real high quality espiaclly in fit and finish. traded it to XSNRG as I no longer run the stock turbo. I do recomend The WRX(TD04) turbo swap as it will eliminate boost creep caused but the small waste gate on the stock unit when flow is increased thru the motor. it also has the ability to perfom better under hard use than the stock unit.
It is a bit of work and fabrication to swap it.

subspeed does NOT make them anymore. Read all the text carefully and you will see why.
ok I read it. looks like he might make more in the future but I would not bank on it. thanks for the correction Will. I just assumed He was still making them. sucks as they were good units.

Also, I've heard it's good to just redo everything back of the DP, to install free-flow performance cat, etc. for the EA82T. What's your advice there? how much should I pay at a muffler shop? is this something a shadetree mechanic should attempt with the help of a buddy who knows how to weld?
Yeah.....direct for for sure...but the TWEs are better, and can be swapped out for 'shorty' new style IHI DP's when you throw a TD04 or better on there, and not have to redo the entire DP back exhaust.

I want to have all this planned out and completed so I can decide what kind of exhaust to get as well.
Posted 17 March 2005 - 06:42 AM
the TWE DP is a direct bolt on to the stock turo...but is NOT a direct bolt on to the rest of the exhaust.
Posted 17 March 2005 - 08:33 PM
Does anyone have a list of other turbos that will bolt to EA82T Headers? I dont mind getting a new downpipe and whatnot... but I would preffer to keep the stock EA82T up pipe.
Posted 17 March 2005 - 08:36 PM
BUT...i have seen some EARLY (89~94) JDM turbo EJ engines that had a 4 bolt exh housing.....it may be possible that those are nearly direct fit...they also had the 90* inlet on the compressor housing.

Even though that mysteriously differs from what your sig says...cool :cool:
Posted 17 March 2005 - 09:08 PM
161 HP/205 TQ to the ground (230/295 at the crank)
Thats right. 161 HP to the GROUND....205 TQ to the GROUND.
That translates into 230 HP at the CRANK....295 TQ at the CRANK...these cars have a 30% driveline loss.
so, thats 161/0.7=230....and 205/0.7=292.857 (i rounded to 295 :-p )

I have a friend with a VF11 for sale. If it wasnt good, i was going to have it rebuilt. I figure its got to be better than the EA82 turbo and I dont want something as big as the TD04.
Maybe i'll try to find a good EA82 turbo just to keep things simple.

Good save, by editing your signature will
Dude, its ALWAYS been like that ever since I had it dyno'ed.
