Anyone use these turbos? searched and found nothing. Which one would be good for a stock bseries. Looking to make high 3's, low 4's.

 

buy a silver surfer from the shodan. for that power goal it's the best bang for your buck unless you pony up for a garrett gt30

 

I run a Borg Warner S256 .70ar and it made 385whp/285wtq on E85 at 16psi on my built LS/VTEC. It has plenty of potential left too...on one of my dyno runs, i had a boost spike to 26ish psi and the dyno read out at 503whp for a split second haha. It sees full boost at ~3800-4000rpm which is great for around town. The biggest selling point to me is the sound of the spool. It makes the perfect dentist drill whirr. I absolutely love my BW.

 

Nice so that BW turbo is comparable to the s2a?

 

The S2a is a "box unit" that's used as a truck application. The s256 specifically goes further into the S2A or S200 class of turbochargers. These s256 IIRC are about 57lbs/min and is a Borg-Warner / Bullseyepower configuration., and comes in a .55A/R (for Garrett downpipe fitment), or a .70A/R 3" Vband fitment using a 74mm exhaust wheel.

The Surfer is about 58lbs/min and is a full Garrett product though customized to fit the larger wheel. The best bet as to "which one" is to know your budget, power goals, engine application and use of the car. The more specific you are the better people here can help.

 

Im on a tight tight budget, which most of it will go to a ram horn, so i cannot go ***** out on a turbo which is why im looking into the diesel truck line up of turbos. The setup will be a stock LS longblock with most likely a Ram horn and e85 i want to make high 3's low 4's (if possible). What do you guys think about a holset hx35 on this setup? im tuner says itll be pretty laggy.

 

You own a sub 160whp rebuilt title hype r, your opinion is invalid. Move along.

 

No one cares.

Back on topic guys, The shodan what you think?

 

Dont beleave you have an nsx unless you show me in person other wise its just words.

ANYWAYS

I have an Hx35 on my d16z6 and I hit full boost around 4500 and pull all the way to 8k. They are alittle laggy but when they hit they move, and can make power up very high. Plus they can make power for very cheap, like 300 for something that can push 400+ (my D16z6 makes 440whp just because its running like 7.9:1 compression)

 

Keep it on topic or i'll go through and delete all of your irrelevant comments. If you have something to offer, then say so. If not, move along.

 

If you're on a tight budget, save yourself some money and get a miniram rather than a normal ramhorn. You dont stand to gain anything from the ramhorn and typically, they are more expensive than a miniram. I would not buy a shitty turbocharger though. Its pointless to spend a few grand on a setup, clutch and tune only to cheap out on and be limited by an outdated turbo. Spend money on a decent one and you'll have it for a long time.

 

Umm. Wrong line of thinking. you plan the rest of the build around that turbocharger itself, then worry about what manifold to use. Not the other way around. You don't need E85 to make those numbers with the correct sized turbocharger that has the proper airflow rate for what you need.

If you're using a full LS stock longblock with LS head, you need to run a slightly smaller turbo than the larger ones you're used to. A standard HX35 is about 49-51lbs/min (depending on the luck of the series). The bad part about it is that your manifold has to be flanged for the HX Holset series, and if something happens to it, you have to find another one of the exact same configuration, or you'll need to retune. It is too expensive for most to repair another HX35, which is why people are going ape-**** in trying to find the used ones more and more.

 

^^Haha...good timing

 

Thanks.

I was looking into the mini ram's but wasn't to sure if the ram flowed that much better than a mini ram, also i actually want to run a holset, its just funny to tell people "its a turd ls with a diesel truck turbo" lol. Ive seen some great number's from holset's. So basically a ram horn doesn't flow much better than a mini ram?

For real? i read in the holset thread that you can run any manifold as it was a normal turbo. I talked to someone who made similar numbers to what i want with an hy35 which is an older version of the hx35 with a bigger back housing i believe and he's running an ebay log manifold. I also have read that the 7 blade hx35 flows 60lbs/min.

 

"Flow" from the exhaust manifold is not going to help you at all if the cylinder head doesn't allow exhaust energy to be efficient, like the LS heads are. You'll have more than enough power with "minirams" and even Schedule 10 "Log" manifolds than worrying about some large runner kooks-style manifold ("Ramhorns" for young people). Again, the Holset isn't a bad series, its just finding the right combination and configuring your manifold to fit. Most that are on the market are T3 flanged and not flanged for a Holset. If that Used holset you find turns out to be bad later, again... really expensive to repair as opposed to a Garrett or Turbonetics or BW or something else.

Hell tell people whatever you want, but just get the better equipment, and don't worry so much about bragging to others.

List out whatever you have (or plan to have so far) please, including future internal engine modifications so you can get the right turbo once and not worry about Holsets so much.

 

 

A ramhorn will outflow a miniram. Dont let me tell you otherwise; however, that isn't the issue at hand. You aren't exactly shooting for the moon with your power goals; therefor, the biggest and best parts aren't required. If your budget had more wiggle room, i wouldnt offer up the change, but the few bucks you save on the manifold can be re-allocated for a better turbo.

The ramhorn manifold is going to shift your powerband toward the upper rpm range because of its long, gradual runners. Airflow is not as turbulent which increases efficiency, but since the runners are much longer than a miniram, it will increase lag. Also, since you're working with a stock LS, you dont have a ton of airflow through the head in the first place. I think a ramhorn will be overkill personally.

A miniram, such as the SLS miniram, would be a great fit for a street/strip car. I used to run an SLS manifold with a GT3255b (which I got from TheShodan) and i have nothing but good things to say about both the manifold and the turbocharger.

 

10,000 Posts over my 6 years of membership at Honda-tech. Call me a post ***** on this one...it doesn't matter.

Thank you and good night

 

Sounds good thanks, just wanted some insight on that. So which BW do you guys suggest?

I asked because of this

http://cgi.ebay.com/ebaymotors/TURBO...item27bdf2c714

 

I would suggest the exact turbo i run on my GSR. The S256 .70ar v-band. At first i thought the exhaust housing was going to be too large, but it is a very responsive turbo. Honestly, the sound alone would sell me on it haha

 

In your case, only the S247 or S252 in the .55 a/r.. Even the S256 isn't needed, but it is nice. Its just that you have the LS head. Otherwise, let's look at a good sized Garrett instead.

As I said earlier,

 

for what its worth, i used to run a HE351CW holset, its got a T3 inlet flange. HX40s and HX35's also have the same standard sized T3 inlet flange. and HY35's also have a standard T3 inlet flange.

you could unbolt it and bolt up any other T3 framed hot side and have atter.



ALSO for what its worth, i didnt like running my HE351CW and i wouldnt run another holset unless i had no other options.

id rather take a t3/t4 BEP 50 trim with a .70 AR hotside over any of the holsets i just talked about.

 

Hx35 is a t3 its just the down pipe flange thats diffrent.. It uses a special 6 bolt I think but you can get them on ebay

 

Great, but again, you're not following me on the replacement parts issue and retune if something were to go wrong for him later. Flanging, fine, whatever, but it doesn't address the issue at hand. ;-)

 

Getting it rebuilt is no big deal, mikes turbo (local shop around me) is a holset dealer, and will basically rebuild ANY turbo. The big deal for me is spool. I do not have 1k to spend on a turbo, maybe $700 ***** out if i make moves. Idc about running a journal bearing or a ball bearing w.e gets the job done for me. I guess i wont be going with the hx35. Hopefully i can find a BW used. Thanks again guys, my question has been answered.
