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.

He's clearly talking about a REAL evoIII 16g if it's around "460ish". The EvoGT is like 499 I beleive. Get your facts straight.

Also don't go making generalized statements about our sponsors such as "don't buy the crap they sell".

No one here was even mentioning an Evo GT, but since you brought it up, do you have first hand experience with that turbo even? If you have to go around flexing your "I know stuff about turbos" information, give both sides of the story, not just some incomplete online-banter you've overheard.

A better statment from you would have been something along the lines of:
"There is some controversy surrounding the Evo 16g GT, if you've been looking at going that route. Be sure you've thoroughly researched your decision."

I was actually thinking of getting the evo3gt. I've heard nothing but controversey about this turbo, yet all the trash talking is from people that don't even own one. I know most of the dsmtuner world is going to hate me for it, but hey, maybe I could prove a point and find out that it's not bad at all.

With that aside. Would it be better for me to run around 20ish psi on a 31mm or 34mm internal wastegate?

 

[slugsgomoo]

the smaller gate will creep more, but hold more boost better, at least with internals.

why not weld the flapper shut, get an SBR manifold, and a TiAl 38mm gate? you've got a couple extra bucks, and externals are simply superior.

Oh, and i'd get something bigger than 550's. You can max them pretty easily, even with a 16g, and heaven help you if you go bigger.

 

[blizz99]

ok, how does this sound?

evo3 16g w/ 31mm internal
650cc injectors
stock front and rear bumpers (mines are dented up)
a day at the dyno and tuning

 

[blizz99]

oh yea, forgot adjustable fuel pressure regulator. I'll be looking to push around 20 psi's

 

[olmytsi]

okay. i think im starting to lean over towards the evo3 side. turbochargers.com sells them for like 460ish. what should i spend the rest on?

why not a sheet metal intake manifold?

Hi all,

Just wanting your advice on which turbo to go for. My T-25 blew so I'm looking for a replacement. The engine is a stock 7-bolt with 103k miles, my mods are: K&N intake, Dave Brode UICP, 1g BOV, Extreme MBC, rewired fuel pump, RRE high-flow cat, and Extreme 2.5" catback. Also have an 2600 and Fidanza so don't have to worry about turbo killing clutch. I also have an S-AFC II waiting to be installed.

I'm currently thinking the Evo III B16g. This car is my daily driver [1st priority], but I plan to autocross/track (road-course) with it [2nd priority] in spring and hopefully hit the 12's on the 1/4 [3rd priority]. Should I go with the 16g or go up to something bigger or better? Right now I'm just looking for a new turbo, I'm not exactly in a position to get any more mods at the moment.

Thanks!

 

[CanadianTSi]

The Evo 3 will suit you perfectly.

 

[Wufei]

Cool, thanks! I was wondering if I should go with an even bigger turbo like an 18g or 20g? The spool-up on those are pretty good too right? Or the bolt-on Garretts or T-28?

 

[blackGSX2g]

I agree with CanadianTSi. Judging by your current mods, an 18g/20g or large Garrett turbo would be too much for your current set-up.

An EVO III 16g can be had brand new for $459 and run excellent at low boost levels, and will allow you to keep increasing boost levels as your mods progress. It is a very potent turbo and should meet all of your needs.

 

[dsm-onster]

Don't forget a nice set of 550s. They work well with safc. And you need them anyway. Upgrade your pump too. So, get the EVO3, 550s, and walbro (or similar) for the price of one 20G.

 

[fulanititoo8198]

Just another vote for the 16G, especially on your Daily Driver.

 

[Wufei]

Thanks for the quick replies guys! I've heard that the best street turbo is a 50 trim?

Also, the Evo III has more potential than the T28 correct?

Right now turbochargers.com has a special for the Mits. Evo 3 B16g, Evo GT manifold, and 2g install kit for $725 shipped, should I jump on that? Guess what I'm asking is do I need the Evo GT manifold (is it prone to cracking or am I not thinking straight?)?

Thanks!

 

[Thomas91169]

Also, the Evo III has more potential than the T28 correct?

yes. even a 14b has more potential IMO than a t28.

for a daily driven car with lots of balls, the evo16g is a great choice.

as for manifold, no, that is not needed. if you go with any other manifold go straight to a SBR Cast or a tubular(overkill though). however, that sounds like a good deal, but i dont know about a "Evo GT Manifold" as ive never heard of such a thing, only of a Evo3 manifold, or Evo GT turbo's(china knockoff of true mitsu evo16g's). id just get the turbo and 2g kit for now and get all that dialed in, the rest can come later.

 

[dsm-onster]

Thanks for the quick replies guys! I've heard that the best street turbo is a 50 trim?

Well, I was going to suggest the 50 trim but around here once you mention getting the EVO3 everyone just hounds you until you get it . And you have safc2. You need atleast 650s to take advantage of the 50 trims potential. And that means running to the absolute limit of your safc compensation and scarry peak timing. The 50 trim is perhaps the highest flowing pump-friendly turbo out there. You can ramp up the boost to over 20 psi on pump and a good intercooler. and it flow almost 50 lbs/min. it is still within 70% efficiency flowing 47 lbs/min at 26 1/2 psi!. . .

You must be logged in to view this image or video.

If money is not as much of a concern, a good bolt on 50 trim and a chip set for 750s would be my favored choice. or sell the safc and get dsmlink, which has the best logger out there incorperated in it and inputs for wbo2, can handle 1700+ cc injectors, etc.

 

[dalatinromeo]

I would def get an EVO 16G or 50 trim if I was in your situation. But if I were you keep the boost down until you have some type of fuel management.

Hope this helps. Stay boostin

 

[Raph]

hi guys.. about the 550cc injectors..and an EVO 3 16g

does anyone make 550cc in HIGH IMP form that will fit a DSM?

i know GST and GSXs use LOW IMP, bu my 4g63s kinda different..im running rx7 510 cc right now (HIGH IMP) since my ecu does it that way (i dont know why they changed all this stuff on the overseas model)


oh i have a dumb question
is this right? evo 3 16g > Big 16g >16g

so the evo III is the asskicker then?

 

[Wufei]

Thanks! I've got an S-AFC II waiting to go in, just need to find a cheap logger to go with it. I think I'm going to stick with the Evo III B16g.

 

[dalatinromeo]

Good choice, dsmloggers.com sell cheap loggers. And you can find them on ebay pretty cheap too. Have fun modding.

Stay boostin

 

[oztofrdm]

a ported evo3, a front mount, and 550cc/660cc injectors and a good tune and all of your goals will be possible. Have fun

 

[Wufei]

evo 3 16g > Big 16g >16g

so the evo III is the asskicker then?

Ah, so you're in Germany? Dunno about the injectors, but yes, that ordering is right

Thanks for the help guys!

 

[saiyansniper]

POSDSM turbo?

Best of both worlds...

 

[1bad92awd]

I would stick with a Evo III for now. If I was going to do some type of a Garrett setup, I might as well shoot for something faster than 12's, and then your talking extra parts like wastegates and manifolds and stuff like that. Nothing wrong with that, but 50 trim turbos are not going to be very "autocross friendly"... nothing worse than waiting til 3800 rpm for your turbo to hit full boost on a track with very few opportunities to go that fast. Evo III could go either way. Just my 2 cents.

 

[ocdiddy02]

i got a 1g and wanted to know what turbo would be better. T3 T4 or BIG 16G???

 

[91gsxboosted]

the big 16g would be easier to install, and works quite well. What numbers are you looking to put up, and what mods do you have done already

 

[blackGSX2g]

The design of the T3/T4 turbine housing is considered more efficient than the Mitsu housing, but for the purposes you require, the 16g will be much less of an expense and it will suit your needs perfectly.
