forcedinductions.com Borg Warner units, do you guys recommend?
Hello,
I am in the process of parting out a single turbo setup for the FD. I decided to experiment with the HX35 a few months back, in short- it did not work like I had hoped. The engine was recently rebuild with a large streetport, 2x1680cc/2x850cc injectors, microtech Lt10, methanol injection, supra TT pump along with all of the reliability mods that can be done to a 13b. The holset is a really great unit but the 18.5cm T3 footprint really choked out the ported 13b on the dyno. We also tried to run a dual 40mm synapse wastegate setup. The setup was a disaster, the boost was all over the map and could not be controlled. Frustrated, I stored the car back in the garage until I could afford to build another setup. The car has been locked up while I have been hard at work. The plan now is to go with a more rotary appropriate turbo. Ideally I would like to buy a borg warner unit, but I will consider anything that meets my dimensions. I would rather go with something on the bigger side, that way more power is always possible in the future. I will be running the car at 400-500rw on the street, I have no intentions to run 6-700rw anytime soon. That would require a completely different fuel/engine setup. These are the dimensions that i am looking for: non ball bearing, oil cooled, 70-80 lbs/min, ~4" compressor inlet, ~3" compressor out, 1.00 T4 or 0.90 T6 or there abouts, 4" exhaust flange. Something around 6-800$ would be great. I have been considering the borg warner s475 with a smaller T6 housing lately. It is on the large side, but the guys on these forums have reported ~15psi by about 4000rpm, pretty damn respectable if you ask me. I am not sure if all BW T6 units have a 5" exhaust, or if some of the smaller 0.90 or 0.96 housings are 4". The s475 is entirely overkill, but it is very affordable and can run at 15-18psi all day long absolutely no problem. I am going to be building my own manifold as nothing that I can buy will be directly bolt in without some sort of modification, especially if I go with a T6. I have done a few hours of research into what material to use. My conclusion is Schedule 10 304 SS 2" pipe with 1/2" flanges, some guys use 316 or even 321, but good 304 pipe seems to work just fine. The turbo will have some sort of a brace on it either way. I plan to buy straight pipe from onlinemetals (~35$ for a 4' peice) and the bends from mcmastercarr (~9$ for each 90 degree bend). We already have a 4" turbo back with two magnaflow race 4" mufflers, so only minor downpipe modification will be needed. From what I have read, I can get away with a single 50mm wastegate, I would like to run a 60mm... but I will be very careful before I go with a wastegate. I just want nice stable boost and no creep. I have found two vendors so far: http://www.diesel-plus.com/turbo_sea...ner%20Airwerks ; http://forcedinductions.com/productsborgwarner.htm What do you guys think? =Benjamin |
The least expensive of the BW will be the 96mm turbine versions. Those will be extreme overkill for 500whp, and will not be fun on the street. If you get the smaller 83mm turbine you will be good, but they are over $1k these days.

Not sure what turbine wheel the forcedinductions s475 comes with. I will check up on that. I would love to hear your opinions guys. If you think my plan is flawed, I would appreciate the critic. =Benjamin |

So the smallest s475 with the Comp- 75mm ind/101.9mm exd, turbine- 83mm ind/75mm exd is what you are saying?

Spend that extra money, and enjoy the car all the time. |
that diesel site has a really good price for the s366. i'm glad i came to this thread. :nod:

My only issue with Jose at FI is getting things in a timely matter.

yes, i'm glad i stumbled across this thread. i think that Diesel Plus has some good stuff and good prices and will be just what i need when i can resume building my race car.

Well, even the S475 (75mm comp, 83mm turbine) will be a slow spooler for 500whp. It could theoretically make 800whp with your setup. For not much more cost, I would go with something like an S362/S366, they will be much more enjoyable on the street.

That is what I have been debating. I have looked at all of the s475 dyno sheets that I can find and compared them to what some people on these forums regard as very good dyno sheets. It seems the s475 makes 50-75whp less below ~4500rpm. From what I have read of Howard Coleman's opinion on what a dyno sheet ought to look like for a street car, he looks for the 200whp mark (usually around 4000-4500), then 400whp at 5500rpm and 500whp at 6500rpm. Some GT35R dyno sheets out there make no more low end power than the s475, some are better. It seems like the s475 is definitely "streetable" depending on who you ask. I would like to see some better dyno sheets though.
=Benjamin If you go with the 83mm version, the price is fairly close to an S366, and I think you would be much happier with that turbo on the street. |

Yeah, he can be slow sometimes. Hes pretty busy most the time, and really needs to hire another guy. I take it you didnt get your turbo yet?
Tuning and motor setup are a big factor in how a turbo will respond. Also, divided vs undivided housing plays good part. The S475 83mm version is fairly streetable, maybe not the best. The 96mm would be horrible on the street without a 20B. If you go with the 83mm version, the price is fairly close to an S366, and I think you would be much happier with that turbo on the street. I was quoted ~650 for the s475 with the 1.10 housing. The s300 units started at around 850 by the sounds of it. There are cheaper s300 units on diesel-plus but they have massive t4 housings so I would have to buy a smaller housing right off the bat. What size housing should I be looking for with a T4 s300 unit? =Benjamin |

The T4 housings dont really get that big, only up to 1.25 a/r. |
Mikesturbo does not even reply to emails . what a waste of time.

ask him see how much he wants for a s475 t6....ill be interested in knowing the results:nod:

i live in the UK with no way of calling him, can only email, ive emailed alot of different guys from the US asking about parts but its like trying to get blood from a stone, im lucky to a response from 1 in every 10 emails, seems being from england means they must either think im wasting their time or they cant be arsed to respond

Seems pretty accurate. This is a S475 with a 1.32 turbine.
Would you run a s475 with a 1.10 on the street based on your experience?

Sounds like the S475 was a non-ett 83mm turbine, but that would be something to double check on.
I would still recommend something smaller, like a 66mm compressor. For the S300 T4, I would use a 1.10 housing. The T4 housings dont really get that big, only up to 1.25 a/r. I am going to give my tuner a call tomorrow and see what he says. He will probably give me the same wise advise as yourself.

I am probably not the right person to ask that :lol: lag does not bother me at all, you just need to drive it the right way! IMO though, if you are going with a compressor wheel that big get the turbine housing to match (1.32). I have seen the 475s make just a tick over 900hp so it's a pretty serious turbo. Also with a properly setup combo you can get 1:1 exhaust to intake pressure ratio. If you are worried about spool just go with the smaller compressor instead of choking down the turbine. |

Yes. $900 + shipping for an s400 75mm with a T4 0.90 housing. I didnt get a price for an off the shelf s475 with the 1.10 housing yet.
I phoned forcedinductions a few days ago, I asked them if their BW units were brand new and if they were all ETT. He told me that they were indeed all brand new units and all had ETT. =Benjamin Thats a low price for an S400 75mm T4, everywhere seems to be in the $1100-1200 range. |
I ended up getting the turbos from a local here in aus for $1550 delivered.
s475 with 1.32 rear housing. Keen to see how much power its going to make. See if i can match what some of you guys are making with these turbos. |

I am still waiting for my stuff....... I ordered a JGS 50mm wastegate and an s475 1.10 T6, along with a T6 flange/gasket and the heavier JGS springs to go with the wastegate from forced inductions in early may. $990 for the turbo/gate, plus the other items and shipping- sounds like sweet good deal! When I was trying to buy the parts I always seemed able to get hold of JZ by phone. I told JZ MULTIPLE times that I needed this stuff ASAP. It was supposed to be shipped in mid-may. The payment was only put through at the end of may. Then when I contacted JZ to straighten it out he told me that the wastegate was backordered. Ok, fine. So I told him to ship the turbo and the flange so that I can get my manifold build while we waited for the gate to come in. The stuff was APPARENTLY shipped June the 16th, but I cannot even be sure of that because they seem to have a problem with giving me the tracking number for my package... Now that I am trying to find out where the hell my stuff is, there wont be much of the summer left by the time the car is finished. I have tried to call somebody at forced inductions multiple times a day for about the last 6-7 weeks, even trying different phones. Ironically, FI does not accept calls from people who block their caller ID's- very convenient. So, to say the least I REALLLLLLLY hope and need the package to shows up in the next couple of days or else I will have to file a dispute with VISA over the transaction, which I am told can take 4-6 weeks to get resolved. The most ridiculous thing about this entire ordeal has been that I need to move out of town ASAP to continue my physics degree at a nearby university, this car project is going nowhere quick and is really putting my plans behind schedule. Before I bought the turbo stuff through forced inductions I had a good read on the turboforums to see what kind of sellers they were. From what I read people were happy. JZ was helpful when I had questions about the items before I bought them, now the guy seems to have vanished. I wish that I could drive down there in person to straighten this stupid situation out, but I am about 3000km away... Any thoughts? =Benjamin |
Jose is a good guy and easy to deal with, but now and then they are slow. Could be short handed or waiting on parts, it tough to say. If I could find his cell number I would give it to you, because waiting this long is no good.

I understand that he may be a good guy, but, customer service is not THAT difficult to maintain. Simple emails would have done it for me. I mean seriously, if there are delays- fine, but at the very least keep me in the loop ESPECIALLY when the payment has gone through months ago. People usually like to know where their money has gone to. And by "usually" i mean 100% of the time. =Benjamin |
