anyone using Borg Warner S472/S475??

[SMP142]

i have been looking at borg warner alot lately. since it seems like garrett's prices are going up more rather than down. know of anyone running the S472 or S475 turbo? i heard its comparable to the GT42 or the PT74. i cant seem to find much online about them. any info would be great. -Brian

i dont think the 400s are small.. i think the 300s are smaller? I really have no idea.. lol.. couple people on SF have experimented with them

[fandffan]

heh heh. Borg Warners are amazing turbos! My friend works at a shop he knows a lot more about them than I do. So I'll have him get on my account tomorrow and post for you. If i were to ever go single i would use a borg warner.

There's a Supra here in Muskegon, MI that has a borg warner turbo with M trim. Saw it on eBay recently and I think xceedspeed.com's forum. You could probably contact the seller.

yeah i have a borg warner on my diesel truck and i am really pleased with it. just trying to find people that use them on gas engines is a little tougher.

i think those will be to big, get an s366 or larger s300 instead. google borg warner turbo, theres tons of information on them

^ SHOOSH!

IF YOU DON'T KNOW, DON'T SPEAK!


s300 or s400 series are good turbos. Garrett copies with newly designed compressor fins. Holset copy turbines (most of the time).

IIRC the s400 flows about 60lbs of air.

Plenty of parts out there to rebuild them too!

******Edit, I have attached a comp map for the s400.

Yeah a wittle tooo big.

I know Borg Warner makes different housings for the S400 line. Take a t4 foot print one and have a local machine shop mill it out for you.

[SMP142]

yeah i am pretty sure i can get a t4 housing for it. what would the machine shop mill out? now will getting a small a/r help compinsate for the large wheel?

The turbine wheel bore.

YUP!

[SMP142]

thanks for the info. whats your take on divided housings? good bad?

[perpetualthought]

how much power are you looking to make?

[perpetualthought]

bullseye performance sells the housings for about 400-500$

thatas a big ass turbine wheel.. fwiw a p trim is ~ 75 mm iirc.. 300 seriies is probably more of what your looking for i would imagine

[SMP142]

yeah i know its a huge wheel. i am just trying to see if i can work with it b/c this guy i know can get me a good deal on one. we'll see. i might try that housing thing. well i am not sure of my hp goals. always want more. this is what my swap is consisting of though so i really dont knwo what to go off of.

thats just my motor stuff for now. next year i wanna take the head apart and do some more work to it.

72 with that size turbine i say 850whp is possible.. it will come in late.. like 5500 or so..

[SMP142]

would a 75 be a better choice? the guy also has setup with a 75 on compressor side.
