I bought a brand new turbo off of E-bay. 57 trim compressor, 50AR Exhaust housing, 63 AR compressor housing, internal wastegate set to 10 lbs. Is this too big for a 7afe? All I can get out of it so far is about 4 lbs. of boost. I will post pictures of my setup in the next day or too. Seems to spool up kind of slow.

Yeah, sounds way too big, what kind of turbo is it?

It's a t3/t4 E. Give me a day or 2 to get the pictures developed. If it is too big, then is there any way to reduce the turbo lag?

Here's a link to the turbo I bought.

yea

way too big

you got yourself a turbo that makes 500+ AWHP in a awd DSM.

Yeah, the smaller t3/t4 turbos can be alright on a 7afe; but your trim size/compressor housing etc is way too huge

Thanks everyone. Hey Nik, can you E-mail me down2turbo's E-mail address so I can try and work this problem out? Thanks.

u dont research turbos before u buy one....... why would u spend a couple hundred dollars wihtout knowing if it will work out good

did u put this in yourself?

hahahah, this is a funny topic. i posted it at a few other car forums and they laughed

Can someone explain the water cooled and oiled cooled difference. Also, i think i know, but i would like to know the advantages of the ball bearing and to normal (what is normal) Just for my big head knowledge base

Ball bearings basically mean the turbo spools without friction being an issue. Normal has slight friction- so slowly spool up time and more turbo lag

water cooled means the turbo is cooled with water; oil is cooled with oil I'm not sure what's required out of a water cooled setup (what lines you have to run)

Don't get to read: http://www.6gc.net/forums/index.php?showtopic=5574

and all the articles it links to. Yes it's for the 5sfe, but it spends a lot of time on turbo principals you need to understand.. I really should finish my part..
