I had two s4 turbos sitting around and i was kinda bored and started to fool around and take one apart. I need to replace the s5 hybrid turbo because i think it has a bad oil seal it was done by majestic and the guy i bought it from said it had a 60-1 wheel on the cold side sorry dont know if that is the turbine or compressor and a ported stock housing to fit it. But i might rebuild the s4 turbo since it is out already and take the 60-1 wheel off when i pull the s5 off my car. The thing is i want to put a bigger cold side housing and dont really know want i should use. Think i should get a T04B housing but dont know what A/r to get or if that wheel would fit. Not going to be running alot of boost 10 to 12psi at the max.

wow you should run a small hot side if you quick boost or something a little bigger for mid range just depends on you. but im going to send you a pm of a guy here on the forum who know his turbo's pretty well. His name is lance from LMG

If you are running stock ports use a 1.15AR if you are ported go to a 1.30 to 1.35 If you are running stock ported 12A go with a .96 to 1.1

Don't undersized like 99% of they people who don't know what there doing just to get "quicker" boost threshold. The added back pressure and rocketing pre turbine EGT's is hardly worth it.

Stock ports for now think my oil seal in my engine is gone or it is my turbo. Just building the turbo for the fun and the learning experience. But isnt that a pretty big housing? Sorry kinda new to this and where should i get my rebuild kit i was looking at turbo city searched it earlier and that site and another one people used cant remeber but some where saying not to buy that kit but didnt hear anything bad about turbo city. The hot side will be stock for now but can i do that? Have a 60-1 cold side compressor wheel(if it is) with the 1.15a/r cold side housing and a stock hot side i am probably going to get flamed for asking

right now i will have stock injectors just because i am going to figure out if my engine is going to have to be rebuilt so i wont be boosting much have a boost controller and a fcon, and a wide band and a gcc soon to come( next weeks pay check) so i will not blow my engine if it is not already going. O forgot to tell that i had to take the twin scroll out because the arm broke off and beyond repair so i just took it out and need to have that welded. I also plan to match the exhaust ports kinda like a s5 and need to port the waste gate. Also kinda confused on this a/r and 1.15 cold or hot. And is the cold side the turbine or the compressor. If you guys are talking about a 1.15ar cold side that is huge. Thanks

You guys were talking about the hot side but i sm going to keep that stock what ever that is just looking to change my cold side housing still want it to spool quick though i know i will have lag. I am kinda looking for a bnr stage 2 or 3 kinda thing just doing it myself and a little different.

The 60-1 is about the biggest you can go.
Anything bigger would start to hit the LIM.

Sheez, how much do you want?
The 60-1 has the potential to hit around 400hp!

Use your 60trim and use a larger hotside

I think the 60-1 was trimmed down because it still has the stock s5 cold side housing just bored out to fit it in. I just wanted to put a to4b cold side housing for a little more flow.

Pics?

Just go with something like my avatar... it's only 5' tall!

This is exactly what I did, but with the t04b compressor wheel and backplate as well. Bolted right up to my s5 stocker without any problems. I don't have the engine together yet, so I can't tell you how well it spools. Make sure, if you change wheels, that you have the rotating assembly (chra) balanced at a turbo shop before you put the housings on.

What size t04b housing did you use? And did you rebuild it your self because i am looking at place to get my rebuild kit. Trying to find a t04b just for the housing and back plate right now. I do have a pic of the turbo on my car vs a stock s4 but no all that great quality but i will post it up.

Still has the stock housing it is bored out to the max though that why i want to go to a bigger housing.

http://cgi.ebay.com/ebaymotors/Garre...spagenameZWDVW It is a .60ar cold side and looks exactly like the one housing on a stage 3 picture on the bnr site. Is it worth it? Just need the housing and looks in good shape.

RETed

That'a iffy.
Most turbo builders will not mill the stock compressor housing to fit a 60-1 wheel in it.
The metal gets too thin.

Can you confirm if it's a 60-1 compressor wheel?

Even an H-trim will be larger enough to warrant using it's own compressor housing versus boring the stock compressor housing out...

I am not 100% sure how can i tell? I need to take it out of my car still.

Pop off the compressor housing and measure the wheel...

You need a dial caliper that can measure down to 0.001".

Mine is a .60 a/r (cold side). I bought the turbo used on ebay. It had worn bearings but a good housing/ wheel/ backplate. No boring, machining or mods were necessary. Bolted right up. Yes I rebuild all of my turbos myself....it is not difficult. I also bought the rebuild kit and a 360 degree race bearing from a seller on ebay as well. Pics:

According to Ted's excellent chart, mine is an "s" trim t04b.

Here are some pics of the differerence in the housings one on left is stock a4 and the right is moded s5. Measuring the out side of the wheel is is about 2.75 inside is like 2.20.

Looking at the chart mine is either a h or v trim wont know untill i go back to my house with my dial caliper but i do know it is 2.75 because it is right on the money on a ruler and a ruler type caliper thing cant tell the minor yet it is over 2 though.

Just measured it, minor is 2.18 and the major is 2.75 so it is a v trim.
