just got a TD04L, mint condition for cheap.
 
its off a 05 impreza, so its the 3 bolt kind. just wondering what these things are rated at from stock in terms of psi. and what this thing is capable of when turned up to a higher psi.

note, motor is a d16y8 is anyone has done this setup before, link me to there setup or lemme know how it turned out. thanks

you can expect just about the same as every turbo that sized and as for factory psi look it up im sure some one has posted how much psi it has

rickg 05-24-2009 12:31 AM

honestly, i have been looking everywhere.. i cant find anything about the stock psi rating. in terms of hp its capable of.. im only aiming for about 200whp right now..and i know its capable of that. found a similar setup on turbo16.com with about 195whp on 10psi. with almost "instant boost"
but in terms of the stock wastegate settings, i cant seem to find them anywhere.

if i find a link for you then you owe me five dollars via paypal.

rickg 05-24-2009 12:58 AM

naw. ill just wait till i have it all hooked up and see what it reads on the boost guage.
i was just curious.

thats a good idea wait til it hits 13psi on an untuned y8. why dont you just test it and see how much boost it makes. and im just curious how cheap is cheap when you say you got it for cheap

rickg 05-24-2009 01:03 AM

i paid 150$ canadian, wich isnt super cheap compared to what some people on here pay for stuff. but i know the car it came off. and its absolutely mint. spins like butter, not a bit of shaft play. i know i have seen people get them cheaper. but i think its still a steal.

rickg 05-24-2009 01:06 AM

and since this is my first time boosting anything... im not sure how to test it.. how would i go about testing the wastegate?
yea, hook up some sort of a a vacum to the nipple obviously.. but whats the ideal way to do this.

from what i know of the wrx is that the factory boost is set at 13.5 psi. im no expert of the wrx or anything but thats what i have heard. now to test the wastegate remove it from the turbo put it in a c-clamp and use vaccum hose to hook it up to a tire pressure gauge and pull on the actuator arm then let goand what ever the gauge reads is how much psi it is rated at also keep in mind these turbos have the adjustable wastegate arm so boost pressure is slightly adjustable

ok thanks. ill find my tire gauge and see if i can figure out a way to hook it up so i can test it. if not. im over it. ill do it another day.

another question. is the oil/water lines, i have been searching. and i cant figure out wich is is inlet and wich is outlet. as for the water lines the most i have come up with is "---- them you dont need them"

should i use the water cooling? or just cap them?

and as for the oil, wich is in/out?

Scott-EP 05-24-2009 06:51 AM

the water lines dont care what direction the water flows. either direction is fine.

the boost at the actuator is probably around 5-7psi. almost all stock turbo cars have some sort of ecu boost control that raises it to what it needs to be.

::EDIT:: i just noticed you said oil too. the smallest hole is oil inlet and the biggest hole is oil outlet, the rest are water

saturn 05-24-2009 08:49 AM

which tdo4l is it?

ok thanks man. i was wondering to..since i got you in this thread and you seem pretty smart. would i be better off keeping the internal waste gate, or welding the flapper shut and running a external?

its off a 05 wrx sti.. its in my trunk, so i cant get the exact numbers off it right now

the words vacuum and pressure are not interchangable. The wastegate works on pressure, that's what you test it with, and some kind of an air gauge that will read down into the single digits.
The oil really goes in at the top of the chra, so that it can drop straight out of the bottom from gravity, and then back into the oil pan.
The water lines don't care about direction of flow.

also you know with this turbo either you are going to have to either rotate the center section or build a top mount manifold for it becuase the oil drain is on the exhaust inlet side of the turbo

yes, i do know this. im gonna make a small top mount manifold, monday i am ordering flanges from weirtech, and im gonna mock something up, tack it all together and get someone else to do all my welds.. mine look like..well.. not like welds. haha

iceracerdude 05-24-2009 03:08 PM

I'm with you brother, good welding is like artwork to me, and I'm not very artistic either. ---- it, I don't do own surgery either...mans gotta know his limitations.

thanks.. thought i was gonna get the "this is HMT" crap and ppl expect me to just giv'r and do it myself

txdohczc 05-24-2009 03:16 PM

ok cool just making sure you knew that before you made/bought a manifold for it then realized later it was up side down

rickg 05-24-2009 03:31 PM

well that was the main reason i was asking what was the inlet and wich was outlet.. i thought i would have to make a top mount..and was right

i would keep the internal one for simplicity if it isnt a high powered build. being that you are using such a small turbo, im sure you arent going for much.

yeah plus its more cost effective to just use the internal that way you dont have to buy an externals and all that other ----

rickg 05-25-2009 09:18 AM

well this is just my summer build for this year. over the winter im building my spare block and going for higher hp numbers.. but yeah. ill just keep the internal i guess. thanks
