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.

If your goal is between 500-600 then I would recommend the GT40 56trim with the rest of the setup I mentioned. Your in Philadelphia, thats where I came from. Try talking to RDRKT. He uses a 2.4 and a GT40 turbo. He dynoed 560awhp and spools really quickly.

I second this choice for you.

GSX- I have always said I wanted the .68 t4/t67 to go on my 2.4, but you have me wondering about the .58. Is there much of a top end loss or flow restriction by going with the smaller housing? I know the .68 will support 700whp, but I'm not sure about the .58.

I have a good friend that ran 10's all day long on a T-58/Ptrim in a .58 on center T4 housing.

He recently swithed to a bigger compressor(little smaller than a T67) in a .70 housing and now runs 9's.

I like the .58

was this on a dsm? 2.0? 2.4?

It's on a 2.0. Wes Hess http://www.hesspower.com/

I would recommend 2 different combos, depending on what your goals are.

#1) GT40 56trim in TO4S cover with P-trim in .58 a/r T-4 housing. (600whp+ potential)

#2) T67 in TO4S with P-trim in .58 a/r T-4 housing. (700whp+ potential)

I thought you said that the P trim was out dated?

I thought you said that the P trim was out dated?

I was going to be sneaky and run the gt37 tw.....

Also thinking about some of the sound performance stuff..

P trim should help with spool up.

Hi,

I did use the search, but couldn't find the answer.

I'm looking for a Turbo with good/best top end power for Highway.

Is that right, the bigger turbo --> the better top end?
(FPT28, Big 16G, 50 Trim, 60 Trim -- biggest top end?)


Thanks a lot...

Mike

generally, the bigger the turbo, the more power you'll make.. obviously. but it's all about airflow and matching mods.. a more realistic question would be to ask yourself how much horsepower you're hoping to make and what turbo(s) can do that for you.

 

[oddrob]

Yes in general the larger the turbo, the more lag, but the more it holds the power on the top end.

Can't decide star performance(stage2 $2800) or hanh racecraft(stage 2 $3400)?????????



Help me out here!!!!!!!

Hey we'll forigive you this time (though the mods might not) this has been discussed many many times. Take a look at the NT turbo conversion section of the forum. It has discussions about what you'll want to know and what you'll be getting into. When you try to decide between HAHN and Star you're getting yourself into a personal preference battle. Some say Star because it has better power potential, a bigger turbo, etc... Others will say HAHN because of their superior customer service and their installation instructions are complete where Star's are kinda hard to follow (so I've been told by others who have done it) Some people will say sell your non turbo and buy a 1G turbo car and save yourself the money and the hassle. Whatever you decide first of all you need to do some research. The SEARCH button is your friend. Good luck and happy boosting (once you get there that is)

(though the mods might not)

Especially the crankier ones.

im getting a new turbo for my car im currently running the stock t25 and im wanting to go bigger im looking for a turbo that will put 350-400 whp down at less then 20psi as thatis all im going to run till i get a new bottom end what turbo would you recomend for something like that

 

[Talesin]

Well, you might get by with a B16G or Lancer Evo 3 16G if you're just looking for 350, but to pull off 400 safely, you'll want a MHI 20G or one of the Garrett setups. Go look through Slowboy Racing. I think they mark down maximum advised outputs on each product.


Also, here's hoping you have all the fuel and exhaust mods to support it. Not gonna get there just by slapping on a big turbo. Gotta do it right.

 

[1badturbo]

im goint to have all the supporting mods.Are slowboy turbos good at all i was looking at the site and saw the precision 5252e and was wondering if anyone has used that turbo on there car

 

[NewB2dsm]

Wait a minute. You are wanting a turbo that can made 350-400WHP at only 20psi?

Thats going to be a pretty large turbo man, and why only 20psi. Im guessing you heard or think our motors can only handle 20psi? If you are going to have all suporting mods, fmic, injectors, exhuast, fuel pump, the list can go on and on. Then you can run more than 20psi on race gas maybe even pump gas. Do some research this question has been asked hundreds of times.

 

[Precision]

OK, so I'm running a 2.3 stroked motor with 8.5"1 compression, P&P head with crower stage 3 cams and an EMS. My question is what turbo should I run? I would think that with the added displacement and the cams something like a FP3065 would have too small of a turbine housing. I already have a huge FMIC and hard piping. And big enough fuel lines to run this thing on Alky. Supporting mods is not an issue.

 

[Verticaljump1]

The FP30 series housings flow really really nice. If you've got the money put on an FP3065, or go with a full garrett GT35R, the bolt on housings are too small. You may want to check out the 3575 also, if you're looking to make huge power. Don't call me a jackass, but if you're not looking to make power near the 600's, I would go with an FP3052, exhaust flows very well through their housings, and your car would be so streetable between the spool time, lb./min. flowed on pumpgas, and the stroker. You'd be spooling that badboy at around 3300 and make very nice power on pump gas. Just my 2 cents.

 

[1badturbo]

i only want 20 psi till i get my bottom end built then it will go up from there but as of right now i want 350-400 whp @20psi or less i also have a small shot that I'm going to put on top of that to satisfy me till it does get built

 

[1badturbo]

also as far as supporting mods go i have a front mount,720's,waldro(forgive spelling)255gph intank pump,3inch o2 housing with dump,3inch downpipe and exhaust,safc,what else do i need

 

[93formula]

Just FYI it is horsepower or detonation that kills motors not boost.

 

[Verticaljump1]

Any of these turbos will make that power on pump gas and about 17psi (350whp)-22PSI(400whp.). I've seen awd's with stock cams, pulling 385whp on 22psi pump gas, with fwd you can get more power to the ground.

FP Green
PTE SCM5031E (.63 A/R.)
Bullseye TO4B (V-trim)
AGP RS49T

Use a 50trim compressor wheel, it'll make that power with decent tuning, and likes to flow nice with pump gas. You can get 22psi out of it with zero knock if you know how to tune, and in many cases past that. Power isn't going to kill your bottom-end, lack of tuning will. If you're knocking more than a girlscout knocks on a door cookies (I know, horribly cheesy ), your motor isn't gonna like it too much. Get something that flows efficiently, wow that must be a 50trim . Good luck, and nice support mods, but it looks like your missing something. What maf are you running, a stock 2nd gen? They flow decent, but it'll start missing counts around 400-450hp, get a gm maf, that combined with an afc you will have rock solid tuning and a maf that'll last you up til 550hp at least. Plus you get to make super cool bov sounds . And your going to have a hard time tuning 720cc's with just the afc. It can me done, but save some trouble and upgrade to MAF-T, or I guess you could run standalone .

 

[GSX4LIFE]

The FP housings are too small for a 2.3. They dont flow nearly as well as 4bolt T3 housings. It is a nice housing on 2.0L street cars but not for 2.3's & 2.4's. (would you put a GT35R on your car with a .48 housing?) The FP housing is still a bolt on housing. It is the best of all the bolt on housings, but a bolt on regardless.

Oh and a bit of a turbo lesson here guys. I was all interested in the FP3575 as well. Man, a T67 with a GT37 turbine? Hmm. Sounds really interesting. Oh, until you find out that the GT37 is nothing more than a Garrett T350(stg 5) T3 wheel. The same wheel that has been so good matched to the GT40 56trim. The same wheel that has powered thousands of SC61s. The same wheel I have had for 2 years. And if you do your homework you find that it isn't a very good match to the T67 63trim. A P-trim is a much better match. The T350 isnt large enough to take advantage of the T67's 75lb per min flow rating. yeah funny things happen when Garrett changes the name of a wheel.

 

[Talesin]

Well, you lose more across the transmission on an AWD, but the AWD can put more power to the road overall.
