2010 Borg Warner Airwerks Turbo catalog
here is a good comparison photo of the garrett 40R vs precision 67 vs BW S300SX 83-75 (88-75 and 91-79 are the same size as this)
its pretty interesting to see how much larger the BW 83-75 is compared to the 40R garrett and precision
I agree 100% the 83/75 could work very well for your application. If you plan on using the stock cams for a while it makes the most sense to be on the 83/75, once you get the bigger cams in the 88/75 could give you additional top end. You absolutely should never use anything giant oversized compressor housings like you asked about
The turbine housing you select depends on the manifold design - twinscroll (divided) or singlescroll (undivided). If you are buiding the manifold yourself its a good idea to build a divided T4 manifold pairing cyls 1/4 and 2/3. Also ~30-40% shorter runners than what you are thinking would be a good idea. Bigger cams are a must, especially if you have headwork... the stock cams will not work well with headwork and a big turbo

so ill have to stay oem for a while. but it gives me time to keep it at low boost to break the motor in.

Looking at a bigger turbo than my actual GT4094R for a 2.4 l stroker, i see on Full Race web site that there are 3 similar solutions, the "old" S400sx 71 mm, the S400SX3 71mm, and the billet K29, what are the characteristics and difference in spool and power between these, and how do they compare to a classic Garrett GT4294R?
Thanks in advance....

Geoff,
Is there any reason why the BW turbo's don't focus on making the compressor nut smaller in diameter to essentially increase the flowable cross sectional area of the compressor inlet? I hope that makes sense to you.

AND
I need Tial to make a housing for the S400's Make it happen for me Geoff.
Maybe I can take a turbine housing and have it machined to fit the BW.

-genuinue BW turbos use a VERY beefy 11.5mm shaft, with a 14.00mm compressor nut.
-garrett/precision style uses a 9.8mm shaft and 14.6mm nut
i can post up some pics of this if you are interested

based on what ive learned recently, i would not recommend the K29 at this time, it is an older design and the S400SX aero is more advanced. The only advantage the K29 has is that it is a smaller size than the S400SX so it can fit in tighter engine bays

Im sorry, but i dont follow why you would want to convert the S400SX turbo from twinscroll to singlescroll? I can help with custom housings, PM me on that, but its not something i recommend

the race compressor cover is available but it is VERY large so while it can flow a bit more air at huge boost levels it will also be more difficult to fit in an evo, so you would have to see what your space constraints permit and of course this will depend on manifold design and turbine flange location

I'm curious - whats the most power anyone has made on a S300SX 83-75? Its been becoming conspicuous to me that while they seem to offer good spool, I've not seen any exceptional power vs. compressor size/hp rating from any Borg Warners. GT3582Rs have been known to go over 600whp and GT4088Rs >700whp, yet I've only seen results of around 500whp for 83/75s so far yet they are advertised as a 68lb/min turbo (same as a GT40R peaks at) so should really be showing numbers in parallel with GT40Rs?
Anyone?

Im in the same boat. BW seems to take alot of time to get leigt results. I have been in talks with both Eric and Geoff at Full-Race in choosing a turbo for our 1000hp stock ecu build. Im sure the wait will pay off. Been a while since Geoff has posted some news

and i know of a KA24de 240sx made 7xxwhp on a S372

Cheers - will have a look there. 7xxwhp from an S372 should easily be expected, its a HUGE turbo. If 68lb/min is to be believed, we should be seeing way over 600whp from 83/75s... unless all lb/min are not created equal.
I'm thinking about going for an 83/75 on the premise that its going to at the least give me everything a GT3582R will at a lesser price and a bigger presence, but there is no point if its not going to make as much power.
