I dont know what turbo to get...so confused.

[motorvated]

Ugh. thats all i can even say. Ive been looking and reading on turbos for 3 weeks now, and im not any further tonight then I was the first night. My car is a 1.6 L. Im looking for a T25 turbo. Anywhere from 225+ HP. See the problem is, I ask all my turbo questions to my one friend. He has a 550HP rx7. Every turbo I show him, he tells me is junk. The efficiency is garbage, to big/to small. All kinds of things. I dont understand. He recommends this turbo http://www.turbobygarrett.com/turbobygarrett/catelog/Turbochargers/GT28/GT2871R_743347_1.htm

But I dont have the money to buy a new one. Im TRYING to find cars that come stock turbod, and take a turbo from one of those. I have NO idea how to find the above turbo, used. Ive seen tons of GT2871Rs, but there are 7 differant ones. The turbo I was going to buy was this one. http://cgi.ebay.com/ebaymotors/BRAND-NEW-Garrett-T28-Turbo-240SX-S13-14-SR20-300Z-AE86_W0QQcmdZViewItemQQ_trkparmsZ66Q3a2Q7c65Q3a3Q7 c39Q3a1Q7c240Q3a1318QQ_trksidZp3286Q2ec0Q2em14QQha shZitem130269341388QQitemZ130269341388QQptZMotorsQ 5fCarQ5fTruckQ5fPartsQ5fAccessories

He told me its trash. Can someone else besides him, help direct me in the right direction? All of this BS...gives me a headache.:afro:

forget the T25, just pick up a T28. A T28 on a 2.0 spools hard around 3300 ish, so its gonna be more laggy than that on a 1.6. A disco potato is even more laggy than that and on a 1.6 it would spool pretty late. T28 can take you to 300whp, and if you are going to be going past that, your gonna build the block anyway (unless miatas are boost freaks that I am not aware of)

[motorvated]

you kind of contradicted yourself..You told me to get a T28, then told me how bad its going to lag

[92sileighty]

well 1st of all establish a "real" price range

[Vr-4-Life]

dude get a small garrett t3 50 trim tops.... your not gonna be making big power on a miata anyway plus you dont need to since the car is light... go smaller turbo for like 12psi and you will be happy. it will have better response since a small spool time plus it will hold plenty of boost to redline...

[motorvated]

what do those come stock on?

[Vr-4-Life]

uh... you can get a stock t3 on a few cars volvo and ford had a bunch for awhile... i dunno about now though.. just look online for a smaller garrett t3. and i worry about used turbos.. you can tell shaft play but you wont know the condition of the seals till you put water or oil through them.

[motorvated]

See thats what im confused on. You say run a T3 tubro..theres like 10 T3 turbos.

[Renegade_]

you kind of contradicted yourself..You told me to get a T28, then told me how bad its going to lag

Its gonna lag less than the disco potato you posted. The only turbo that isn't gonna have much of any lag on the 1.6 is the T25 and that thing's tiny as hell. 260whp TOPS

[motorvated]

Ok..so a SR20 turbo is no good. A T2560R is no good.. whats left.

[Renegade_]

Ok..so a SR20 turbo is no good. A T2560R is no good.. whats left.

T28 is an SR turbo on the S14/S15 motors and are good till 16-17 psi but at 17 psi your blowing a ton of hot air and it falls off at redline. You can find them for 300 bucks in real good condition. My T28 will hold 14psi all the way to redline, no issues.

[motorvated]

Sorry for my stupidity... Isnt that what I posted? If not, could you send me a link to one like you described.

[Vr-4-Life]

dude i said you can get a SMALL T3..... 50 TRIM TOPS. i mean seriously your gonna be running like 8psi 10psi right?

[motorvated]

Probably around 12-14, until I get a new motor.

[92sileighty]

See thats what im confused on. You say run a T3 tubro..theres like 10 T3 turbos.

that's why he said pick one with a relatively small trim. your car is all about power to weight, picking a larger trim is unneeded.

[92sileighty]

beat me to it ; )

[motorvated]

god I hate being tubro retarded.

[motorvated]

Looks like the Turbo from an SR20 is good for my car. Spools fast and is good for 15 PSI..which is enough for me.

[esunbaboon]

uh... you can get a stock t3 on a few cars volvo and ford had a bunch for awhile... i dunno about now though.. just look online for a smaller garrett t3. and i worry about used turbos.. you can tell shaft play but you wont know the condition of the seals till you put water or oil through them.

I've got a Mitsubishi 13c I could sell you. Which is basically the same as a t3, it's what came on the 87+ volvos. It doesn't have any shaft play but it does need a rebuild, as will almost any used turbo.

[motorvated]

PM sent

What do you guys think about the little 13C? Would spool fast on my 1.6..and I could probably get 12 PSI out of it.

[the4g63]

A Mitsubishi 14b might be a good choice. They spool quick (on a 2.0, anyway) and have put some DSM's into the 11's with the right mods. They're great little turbos.

[92sileighty]

i think you are over thinking things my friend

[motorvated]

how so?^

[92sileighty]

about 4 different turbos were mentioned that you could use on your car, and would most likely all have the same effect, just pick one!!! lol

[motorvated]

true^ Its either the 13C or a turbo from an SR20. SR20 I can probably get more power out of.

[peteyturbo]

Actually the turbo your friend said to get would be awesome for the 1.6 miata..Get what fits your manifold design and exhaust setup though..

[92sileighty]

will you be swappin the turbo yourself? i feel bad to say it but it might be a cool experiment to get both and try them out, cant imagine the gaskets ull go through though. u said your tight on cash and i don't want to sound like a jackass, its what i would do though, but hey that's me and this is you. you also said u would be getting a new motor, if so id go with the 13c.

[ketchup!]

either grab a t3 .42/.48 from a tbird or a new garret t3 super 60

[motorvated]

Going with a t25 off of an SR20. fast spool, and handles the PSI I need.

[240sxDann]

That should work for you just dont plan to run more then like 10-12psi. It will make about 15psi but its really pointless with that turbo.

[blackvr4]

go with this turbo, fast spool and SAFE power

http://www.blouchturbo.com/turbos/IHI_RHB3/

i would say go with any kind of mitsuturbo, but problem being that chances are its going to be easier for u to get a t3 manifold than a td05manifold that will fit a miata.

are u able to get a td05 manifold to fit a miata? if so i would def suggest a 14B. can be had for prolly around 150tops for good condition. the 14b starts spoolin on my gfs talon at like 1900rpms, she has 8.5:1 compression bored 20over

if u want to stick t3

maybe this would be good
http://www.blouchturbo.com/turbos/Garrett_T3T04E_40_trim_Stage_1_048_AR/

if u wanted something a little bigger go with this

http://www.blouchturbo.com/turbos/Garrett_T3T04E_46_trim_Stage_2_048063_AR/

but i wouldnt go anybigger than that, also if id be u i would stay away from BallBearing turbos the spool difference isnt worth the lack of servicebility that can be performed on the turbo.
for example, you blow a journal bearing turbo, u buy a 90dollar rebuild kit and have ur turbo back together for prolly 200-250.
you blow a ballbearing turbo and you will need a whole new center section because those turbos are non rebuildable

so i dont think extra money and lack of servicebility is worth the 400rpm quicker spool difference that you get with a Ball bearing turbo.

just a thought.

P.S. if you are able to get a td05 manifold for ur miata then u are golden with turbo choices. almost any turbo you want is made in td05, so that opens up a whole door of possibilities. u can start out with a 14B and end up anywhere u want 16G, 18G, 20G, 50trim, 56trim, holset, borgwarner, 35r, any forced performance turbocharger.

Hmm... can you take pics of hte hot side for me? i have been trying to identify wtf kind of 5 bolt flange is on my downpipe.. i know its probably some wacky volvo flange. i really hate when people dont follow common standards. regardless i just bought a new obx t3 flange for my DP and im gonna be putting my new T3 on but i always like collecting turbos haha

[motorvated]

Ide like to know the same...since im considering buying it. I believe its a t25 inlet.
For the miatas, most manifolds are T3 and some are T25. Im not sure if anyone actually makes a td05..
Im talking to a guy right now who has a brand new FLying Miata manifold for sale. If he lets it go at a good price, i'll buy that and find a turbo to match it. I'll keeo you updated.


**BTW..thanks to everyone for helping me. I really appreciate it :)

[WRXD]

have you considered joining a Miata or a Mazda forum? A more platform based forum would probably be able to give you a lot more specific info about what different turbos feel like on your motor.

hmm 5 bolt flange, that's not any volvo turbo I know of unless it's a 00+ but I doubt it. Possibly a turbo dodge or Chrysler?

motorvated there's also the mitsubishi 15g from the volvo 850 fwd cars. They're good till about 15-16 psi and have a much better kick. It's not that much bigger and was a direct swap into my car and was a great improvement.

[TurboTagTeam]

I LOVE my Disco Potato. No other turbo will spool as fast and still make 400whp with the right supporting mods. It's unbeatable. Pretty fat torque curve too. I beleive I'm at or around 360lb/fts

[motorvated]

what IS a disco potato?

[blackvr4]

a disco potato is a gt28rs

[TurboTagTeam]

a disco potato is a gt28rs


AND......the absolute BEST turbo money can buy that isnt as big as a watermellon. I'v got the .64A/R HKS GT28rs.

[blackvr4]

what car do u have this on? the rx7?

[TurboTagTeam]

No LOL.... I had a GT35 on the RX7. I have a GT28 on my SR20.

A GT28 on an RX7 would be funny. It would probably implode :) Rotaties use HUGE turbos. Even my GT35 was a tiny little ****er for a rotary. A big snail for a rotary is like a GT47 or a S357.

[Renegade_]

I think you'll be damn happy with a T28 if you go that way - if you do decide to build the motor in the future, you can keep the turbo and just crank the boost up some more; you'll get in the 290-300 range

[motorvated]

Great. The manifold im looking into is a T25 flange. So the T28 will work
