Best turbo?
 

I believe the small 16g is the best turbo for sub 300 whp on a 1.6

300 + whp, it's self explanatory. :skid: :eek5: :noes: :lockd: :yippee:

wohoo i new there was something aliked about you

none is better than another... it's all about application, cost, and what you already own :) Personally I'm shooting for roughly 300-350 whp on mine, but I need cash first. Megasquirt will be on order when I return my basement full of bottle deposits (10 cents each in MI and I have several thousand). N/A still at the moment.

comeon guys post up and let us know what you think

i like the ideas of a t28 or 16g.:crx:

i am surprised no one:firedevil voted for less than 300 hp:firedevil seems we are all equaly maniacal in our quest for power:dancegay: :bigtu:

I voted for them all

all turbo is good turbo

The T3 60 trim or S60 rocks. Flipside just got done switching out a greddy setup that was making 225 whp at 12 psi for a T3 S60. No dyno numbers yet but the owner reports better spool and the car is much faster at only 10 psi.

With the price of Miata's so low, I feel that the cheapest reliable setup is the best/most practical. Hence my quest for doing this cheaply, which I think is easier on a 1.6.

T3 60 trim if youre on a budget. Small (stg 1) 48 trim turbine gives great spoolup and the 60 trim has enough flow for the stock bottom end. Just run it at 12 psi and be happy about all the money you saved. You can make mid-high 200s at the wheel with this turbo and they are super cheap as well.

If you want to start doing a buildup and go for 15+psi, go straight to a T3/T04E 50 trim with a stage 3 48 trim turbine side. I went for a stage 1 turbine and a t04b s trim compressor and it is OK for 15-18 psi in cool weather, but above 85F, the intercooler heatsoaks very quickly due to the low compressor efficiency. I'm gonna upgrade in a few weeks once I finish selling my house.

edit: oh and in case it wasnt common knowledge, all of the turbine housings hook up the same, so you can start with a T3 60 trim and upgrade to a bigger turbine and a T4 compressor later on without redoing your manifold, DP or intercooler pipes.

Of course 300whp+ and I am partial to the GT3271 and GT3076R.:)

I agree, me likes the S60. I need to get it to a dyno soon so I can do some 9-10-11-12psi pulls and show you all easy power with no engine management.

I agree with Beerslurpy, I went with the T3/T04E because I'm stupid and want more power than any miata should ever have.

i didnt like the spool with a T04B-S, so i went to a S60 wheel. It did pull like freaking crazy on the highway though.

The T04B is better than the 60 trim, but that is about it. The stall range is too high for the miata, the efficient range is just too small and the area outside the efficient range is too inefficient. The little island is like 73% and falls off to 50% by the time you hit about 7-8k at 15-18 psi.

The TO4E spools sooner, has a much broader efficient range and when it isnt in the high efficiency island, the efficiency only drops to about 74%. So you can take it all the way up to 400+ whp and it is still pushing cooler air than the T04B-S at its best.

None of this really matters as much if it is cold out, but it often isnt. On the highway, the increased airflow through the IC seems to cancel out a lot of the hot air generating tendencies of the T04B. Theoretically it is capable of 350hp, but you would need a very efficient intercooler and some cold ambient temperatures to accomplish this. Most of that airflow on the right side of the compressor map is hot air.

I don't get all this love for the T3... Why don't you all just run a disco potato or GT2560R??? ;)

T3S60 Now, $200 T3/T4 Ebay Special on it's way... LOL.

the price/performance always plays a big factor. plus it's what I ended up with, so I like to be biased.

i got my turbo for free.:friday:what a nice friend.it comes off a nissan s15 sr20det motor.its a t28 and ball bearing dont really know what one its excatly.went on garrett.com they all look similar.

becouse they all listened to you when you said the s60 was the shiznit. hopefully andy will bring you to your senses and you will run a 3271 like him. how is your motor doing anyway?

Over here mark we dont try to spend as much money as possible, we like cheap stuff that gets the job done. A lot of the time the cheap shit gets the job done BETTER than the Disco Potato or GT2860R.:bigtu:

That's an ugly question... once I get my motor back I will discuss what has happened. I'm not exactly a happy camper about that situation right at the moment. Looks like I will be running an Ebay T3/T4 with a .63 A/R turbine and a "57 Trim" ebay T04E compressor with a .50 A/R, it's a chinese garrett knock off so who knows what the real specs are. The T3S60 I had got damaged slightly.

Mark

whoops! Didn't know you were out of commission!

yeah he holed it didn't you read his thread on m.net i cry for the poor 2L on the pluss side he now has the billet oil pump gears installed :bigtu:

300+hp on miata is simple. gt2871R from ATP turbo (4 inch inlet)(no relation to them...)
The gt3071R is alittle sloppy on the miata. erradic boost. But my car made 331hp and 305tq with the gt3071R at 21psi. Stock motor. But i wish i would have gotten the Gt2876R becuase it is suited for our cars better.

I don't get it...is the question "what's the best Miata engine to turbo?" or "what turbo best suits the respective Miata engines and why?"

You should clarify your poll.

I passed statics, looks like someone didnt! ;)

I think that it is very hard to come up with any difinitive answer to this question. Depends on what you are looking for really. There are a large number of different turbos that have been used, mostly sucsessfully, on the Miata, and some which just plain sucked - if all the threads that I have been reading are anything to go by.

So, the best turbo is the one that you have!

Something went through the motor, it was a stock motor but destroyed #4 and ate up the cylinder head, then debris hit the turbine wheel and damaged a few of the blades. I was supposed to get a built 2L bottom end with pauter rods and arias pistons but that's in question now. It looks like I may end up with an 1884cc bottom end and SCAT rods with Wiseco pistons. The head has been resurrected but has a serious valvetrain in it, but that's hampered by the fact that it still has stock cams. The valvetrain is good for 12,000 RPM according to R&D Valvesprings at 20 PSI of boost, the bottom end should be good for about 8,000 RPM or so and the cams... well we all know what they are good for. Compression should be right at 9:1 or so. Engine management is a TEC-IIIR with 880cc/min injectors.

Racing Mazda perhaps not coming through? :vash:

:bowdown:

Wow! What are you looking to do with all of that power output?

DB

Yeah, Im gonna be shooting for about 350whp on 21-22psi once I get some engine management on the car. I use a Gt3271 but am going to use the 76mm compressor upgrade to have a little extra headroom to make the power on a little bit lower boost since the GT3271 is marginal above 350whp.

more like 400whp now that you have your WI

Where are you getting the compressor wheel and how much is it?

Thanks
