Which Turbo Should I Get [merged] What Turbo

[Ludachris]

Which turbo will be sufficient for consistent 11 second times? I've recently decided on a big 16g, but will that be big enough to run 11s with supporting mods and decent tuning? Remember, this is for a budget street car, so any one purchase over $1k is tough. A big 16g will run about $700-900, which is about $300-400 less than the larger alternatives.

Of course, I'll need lots of practice to run these times, but, I just want to make sure that it's possible before the money is spent.

I have come to the point where my setup is ready for a turbo upgrade. I am pushing my FP T28 to its limits and I would like to change it out before it dies on me. I have been pushing 24 psi and meth into it over the last year and I really don't see me getting any more out of it. I have been looking at the forums and over the last year there have been many people having success with the BW 256. But I am unsure if its too big for what I am looking to do.

My mod list is in my profile. I would like some suggestions as to what would be the best for me. I also have a set of fp1x cams ready to go in as well.

I do not do any drag racing, the car is only driven on the street so spool time is critical. I know nothing will spool as fast as a T28 but i would like it to be as fast as possible.

I would like to see 450hp on 94 pump with meth, and I never plan on pushing it past this. I am worried about breaking things if i do.

An evo III is a consideration but again i would be pushing high amounts of boost to get those numbers and would end up doing the same thing i am doing to my T28.

I have also been considering the BW S256 with an internal gate or maybe even the FP HTA GT3076R as possibilities.

My question is, is the price difference between these turbos worth it?

The BW is twice the price of the evo III and the FP HTA is almost another 1000$ over the BW when I factor in the external gate. I could destroy 2 evo III's before buying a BW.

Or is there another turbo that i could try that would get me to my goal?

I am really at a loss of which way i should go. Suggestions would be great!

 

[gorf]

Holset - read the hundreds of posts about them

 

[Bluefire16]

Couldnt agree more ^^ An evo III would be hard to hit that mark though, it would a really good tune and port and not to mention cams and everything else.

 

[e85_4g63]

A Holset HX35 in the bolt on housing would be an excellent choice man!

 

[Ninharu]

So what would the difference be between a S256, HX35 or even a HTA DSM76 in terms of spool times? I think I have pretty much decided that an evo III wont cut it. Now i just have to decide which one of these would do the job the best. From what i gather all 3 turbos will get me to my goal but price is kind of a factor.

 

[1gDSM4g63]

I'd go with the HX35. It is the cheapest and most reliable turbo and I believe it spools faster than the s256, but the s256 or HTA 76 spool rate shouldn't be a big factor. Were talking about +/- 500rpm difference, they are all low-mid rpm spooling turbos. For the price the HX35 is the best deal and $1700 for the HTA 76 is not worth it.

 

[Steve93Talon]

A local guy trapped like 124 on a BW S256 non-extended tip bolt-on with pump/meth, it's alot cheaper than the extended tip version and if you don't plan on running over 30psi you probably won't see a difference. I saw full boost on my 256 at like 3600, it should definitely be a liveable trade-off for the extra power.

 

[me612]

I've been running my BW for 2 years now and it's been nothing shy of excellent. So chalk up another vote for the S256.

Alright we finally have all the kinks and problems fixed in shadow (cars name), and now the turbo is starting to sound like a meat grinder....sigh....so time to get rid of that lil stock friend to a more powerful approach. So here are my specs. 97 gst spyder with 47k miles on it. All the minor easy upgrades like cold air, exaust, fpr, mbc, and other lil things. But now im hoping to push around 350hp safely. Now the question is which turbo is good for the fwd to get good power and pull. I was looking at evo3 big 16g's for a while now. But i want to be sure to get one that will give me that power and pull that im looking for. Right now dyno on the car is 207hp at 256ftq. Also another question is what addons i should include with the turbo. Im already going to get new headers and fmic with the turbo but hey im still learning so i wanted to make sure i dont miss anything.

Thanks for reading and lets make shadow a fast fun street car!!

Few things I noticed you didn't have on your list that you might need, bigger injectors, AFPR, Wally 190 or 255, Wideband o2 , and something to tune with(S-AFC or ECMlink). 350hp on the 16g has been done a lot but like I said you will need more fuel and a decent tune to reach it. Some people might even suggest an 18g for reaching the 350hp mark without getting close to maxing out the turbo. Do a quick search there are ALOT of threads for the kind of power you are looking for.

 

[Gamble97]

Evo3 16g if you want to play follow the leader. Or if you want to be different and appear to have a stock turbo get a fp t28.
Forced Performance Turbochargers: DSM FP Big 28 Turbo

Puts out about the same as a evo3 16g but w/o the boost creep. Best part is it's a DIRECT BOLT ON. With the evo 3, you need to mess with the damn J pipe, the install kit, the new lines blah blah blah blah. So in the end it the 16g plus the install kit will probably be around the same price as the t28.

BTW, the t28 is good for some 11sec runs. Don't let it's size fool you.

 

[thatblondechik]

The EVOIII 16g will give you all the push you need to reach your 350hp goal and STILL leave room to make more if you want it to!

I was recently enlightened, a Big16g is all the turbo 90% of the DSM community will ever need (as far as streetable DSMs go). They'll get you well into the 400hp range if you do things right. Please feel free to elaborate on this! I don't know as much as I'd like to about turbos and their limits!

And yes, you'll obviously need to address fuel delivery, tuning, and air. A set of 650's would do you quite nicely, a 255 Walbro, SSAC sells a VERY nice short route FMIC for about $250 shipped (at least that's what mine cost when I replace the GReddy POS), 1g BOV's work beautifully and are cheap to come by, and of course the wideband and SAFC for tuning. BUT, if you're looking to go any more than that 350hp goal I'd look into other tuning methods. 650's are about the max for an SAFC.

 

[lq1driver]

low boost 20g or hx35 with dsm link fmic and some other goodies you will have alot of room to play with also bigger turbo low boost is always better

 

[thatblondechik]

bigger turbo low boost is always better

Now who told you that lie?

If that was the case, we'd all be running HX40's. Please research before you post.

 

[Artago]

BW 256 NET.... at least that's what I want.

PS: Glad to hear you're up and running.

Well into the 400whp range? A smaller turbo like the evo3 16g and $500 intake manifold and perhaps a $300 exhaust manifold. Or a larger turbo like a bolton 50-trim or hx35 that costs the same or maybe $200 more after complete install. The difference really is how much you have to invest to get the most out of the turbo. An hx35 or bolton 50trim is very streetable.

OP, the evo3 16g is definately all you need for your current goal, without having to buy the above parts. So don't be afraid to get one if that is your goal. Just know that you should weigh your options and how much it will cost farther down the line when you want another number, IF you want another number.

Lower boost from a bigger turbo to net the same results as higher boost and a smaller turbo is better because of the limitations of pumpgas. Boost is directly proportional to heat of the aircharge (adabiatic process). And heat of the aircharge is directly proprtional to the likelihood of knock. Better pumpgas numbers come from turbos with larger and laggier hotsides. Is the OP going to run ethanol? water/meth injection? Race gas? these questions need to be answered, but generally the most power from the lowest boost is more beneficial for those wanting to get their fuel readily.

I was referring ONLY to his current goals and potential for it down the road. There are obviously other ways to go right now that would get him into the 400hp range easier in the future but for his goals (and price range I'm sure) the 16g is the obvious choice.

 

[dsm-onster]

Exactly. I don't mean to take away from your advice. It is very sound. And very proven. Just elaborating .

 

[djalogik]

i would go with 20g, 50 trim, or hx35.. even though it is true that you 16 can get you to your goal, it will be working a lot harder than the previously mentioned turbos...

 

[habitatguy187]

DSM-onster, How quickly does a hx-35 spools anyway? Faster than a 20g I've read, but I don't think I've ever seen anyone give a rpm range.


EDIT: With the bolt-on housing*

 

[JayRolla]

If you are looking at 350hp at the crank than the 16g is all you need. If you want 350hp at the wheels than I would consider a larger turbo. If you get some meth injection, e85 or race fuel than 350whp is possible with the turbo completely maxed out.

If you get a 50trim like the sbr g50 you will most likely get 350whp a lot easier on some pump gas. In my opinion the 50trim would spool a little later, make more hp and less tq making it a lot easier to hook up with that FWD.

 

[ba109296]

You can make 350 to the wheels with an evo3 very easily. Being fwd a bigger turbo brings you into a whole different realm when driving. Getting traction is a PITA at any speed.
I would just get an evo3, don't buy the kit, put one together for ALOT cheaper and save your money and then do an awd swap on that bad boy!!!

Evo3's are doing low 12's up at high elevation so thats good for 11's most places. That is good enough for what your trying to do then some.

Just make sure you have some way of tuning and also bigger pump and injectors.

I dont know where you have been but 350whp is not easy on a 16g. You need to run meth injection, e85 or race fuel and very high boost levels to get those numbers. Unless you count dyno jets, which I usually take 15% off the whp number to get a more accurate hp number.

Its always better to make your hp goal at a lower boost level and a bigger turbo as long as you can deal with the slower spool.

Im one of those guys at high altitude running low 12's and its taking 32psi spikes falling too 22psi and 22* + peak timing on e85. Not everyone can run race gas, e85 or meth injection all day so I would think a larger turbo would make it a lot easier to hit his goal.

Wow this thread went further than i thought it would have . I read the questions and here are a few answers. For fuel im using 95octane, best i can get in my area without going to racing fuel. Just bought some 650s and new walbro 255lph with a afpr. After reading all the posts it looks like i have more on my table than i thought i did . I would love to do a awd swap on it but ive heard its a ton of money and more of a pain in the a** than i would like to dive into.

Also thanks again for the thumbs up on car running great again. Artago has been there from the start with shadow. He knows the kind of hell i have been through . BTW i hope you got that message i sent to the webmasters about how much you have helped me. Good to see now also ive just became a proven member.

Well for now it looks like im going Evo3 16g with my fmic. Im just doing a light build since this is also my daily driver. You know what they say, the more power you put in the more of a chance that it would blow up.

 

[greylee]

i blew my existing turbo and im going to need a new one can someone point me in the direction of a affordable posible slight upgrade replacement that wont break the bank?



* i did try to search the forums to find the answer myself but i couldnt seem to find it
