Two turbo options. I need to know how they compare.
I have two options right now for a turbo. One or the other will be purchased in the next day or so.
Turbo 1
Borg Warner T04E
54 Trim
.60 Compressor A/R
.84 Turbine A/R
T4 Devided flange
Turbo 2
Garrett T04B
60 Trim
.60 Compressor A/R
Now the different part. This turbo comes with an on-center undevided T4 with a .69 A/R. Now for the price I can get it for, I'm not complaining because I can try to source a T4 Devided housing with a .82 or .84 A/R
How do these two turbos compare. By reading it seems the B will choke up faster than the E, but the trim is larger so how would that effect spool and top end.
links to the turbos.
I managed to barter the T04B down to $250 CAD comparing to $450ish CAD once I get it across the border for the T04E, so what would a housing run me?

The Borg Warner. The other is too small and the on-center SUCKS. Its not a very large turbo and it most likely has a clipped turbine so spool up will be ok. Expect 320~340 hp MAX at the wheels.

Edit: Oops! I didn't read it through enough. The Borg warner is pretty small being only a 54 trim. i wouldn't put it on a rotary. The other turbo is small too and the turbine housing is horrible. Personally I'd keep looking unless you could get the T04B really really cheap (Like $150 shipped) because turbines will run you $100 used.

Well I was thinking to find a new turbine housing in a T4 devided .84 or similar A/R. He wants $250 for it and it's been recently rebuilt. I'm still waiting to hear back from A-Spec on the 57 trim Borg Warner. I think I'll wait to hear from them before making a choice.

How much power are you looking for? Don't run that second housing for sure unless you don't want power after 6k. Both compressors are a bit on the small side. If you were to source a different housing i would try to find around a .96 divided. It will trade a small amount of spool but the top end will be worth it. Especially with the sizes you're looking at spool shouldn't be an issue.

.96 A/R divided no such animal. Choices for T4 turbines that are rotary friendly are as follows: undivided/open valute, .81, and .96. For divided theres .84, 1.00, and 1.15 (which is rather large).
I used to be a Garrett dealer . As I stated, both compressors are on the small side, especially the Borg Warner. The T04B35 is ok, but still smallish and is going to limit power in the low to mid 300's at the wheel. Normally it would spool up quick, espcially if a .84 divided is used, but those turbo come with clipped turbines (Theres a TON of these out on the market, all with simular specs from AiResearch, BorgWarner, Garrett etc. They all are from the 80's erra and were used for deseil engines).

Well I've been reading basically for the past two days on the T04E. Other people have had good results with the 57 trim with a devided .84 T4. I don't want more than 375-390 to the wheels. Fast spool is a MUST.
Also, I am going from a mid 200's HP car to this so I don't want to go to extreme quite yet. I have no problem upgrading the turbo in the future. Or even just getting a larger turbine housing once I am comfortable with the power.
I think a few people have missed the comment about the t04B. If I were to get this turbo, I wouldn't use the .69 housing. I would find a .84 T4 housing and slap that on.
The other idea is a 60-1 but from what I've read the T04B is basically the same turbo just with a smaller A/R (.60 instead of .70)

Well, good because neither turbo you've pick will get you to your power goals "want more then".
If you go back and read all the post you've skimmed about the T04E's, T04B's and 60-1 turbo's, you'll find my name in nearly every thread.

I just started to read about the 60-1's this morning so I don't know too much about them. I've just read the To4e is a solid turbo for someone wanting less than 400 with good spool.
There is a guy here though who hit 370ish on a 57 trim.
60 trim will be fine too, not that much loss in spool.
But again, no one seems to catch this part. IF I get this To4B, it will no longer have a .69 turbine A/R.
What would a T04B with
60 trim
.6 A/r comp
.84 turbine comp T4 devided
put to the wheels. NOT the .69 housing.

Stop repeating that! If you read the very first response (ME!) I noted this fact already.
"The other turbo is small too and the turbine housing is horrible. Personally I'd keep looking unless you could get the T04B really really cheap (Like $150 shipped) because turbines will run you $100 used."
Notice I gave a price for the turbine? Because I was telling you to add that to the already price of $250, after you baught that USED SMALL TURBO and then bought another turbine housing, with the money you spent you could have bought a bigger better spec'ed turbo from the get go.

uhh... I guess I kind of mis-read your comment then. Because you said "turbines" and not turbine housing. I thought you were talking about replacing the whole wheel.
Isn't the 60 trim and .6 AR on the compressor side good for my power goals?

NO,as mentioned 5 times in this thread (by me and others). ITS LIMITED TO 310~340 TOPS, not 375~390. Apparently you want one of these turbo's so bad your ignoring every thing every has posted thus far in hopes of some uniformed newbie who will post that its a GREAT TURBO and will make 500 hp and spool up by 1200 RPM's and for $250.
Good luck with your car
Sorry to be so rude, but MAN............

Well, look at it this way. No where did it say " the to4b will give you THIS xxx amount of max HP".. that's the answer I was looking for. Not a "it won't flow enough, or it won't net you 370''. I wanted to know what it could produce not what it can.
I realized that you did give me the info in your first post, but by your wording I thought you were referring to the t04b with the .69 A/R and not the .84 A/R. So my mistake...
anyways.. whatever. Thanks for information you did give me but you didn't need to be rude at the end there.
