any 1.6 with gt3071 here ?
 

Hi folks after some modifications to my car i am planning to go for tuning to my dyno.

I planning to boost 28-30 psi my engine and i want to have an idea for that i will may expect. So if is here anyone with 1.6 and good power just help me.

My current setup is

Je pistons.Carrillo rods,Arp studs,Cometic Gasket,
Garrett Gt3071, 3'' custom exhaust,
tubular manifold with external wg,
Precision ic 1/2" L x 8" H x 3 1/2" D
RX7 FC II tranny,
Vipec v44 Ecu,650 Sard injectors,innovate wideband,

should see nice broad powerband

Lol.

I'm actually really interested to see your power numbers. Ive heard the spool on a 1.6 with that turbo will be pretty terrible, but I figure it should spool by 5.5k :giggle:

Gl and post up the numbers!

probably going to need 2 banks of those injectors heh.
i dont think thats going to be enough for 30psi on 3071 for fuel.

ok

until today i had a simple manifold internal wg with smaller ic and smaller exhaust

i made 300hp to 18 psi my spool was very good and from 4000 rpm

3071 is 500rpm slower from 2560 but after is a beast.

i took 40hp at same pressure when i change from 2560 to 3071

i gotta get the **** outta here

here is a photo from manifold i will make more shots tomorrow

Odd place for an engine damper. Holy turbocharger batman.

I'd love to see the dyno plot for this.
I have a hard time believing that a 1.6L gets that large 30r fully spooled by 4k.
Call me a nay sayer. I just don't.


But if it does, WOW.

I would love to see that too. If it does I am selling the 2871r for the 3071r..

If you manage to get that sucker to fully spool by 4k I wont look to get a 1.8 anymore.

awesome stuff man i like it alot.

Can't wait to see where this goes. Good luck! I just wish I had the money to do something so crazy.

isn't the place of damper there. Is just moved becouse we work the manifold.

I will post more photos when is finished

Honestly you are my hero newb.

You might catch a lot of shit for strapping that ginormous turbo on there...but I think it's cool.

In for dyno chart.

Well, I hope that you are full of shit. Simply because it will make me feel better about swapping from a 1.6 to a 1.8. ;)

In all honesty I hope that you can prove it, I think it would be fantastic if someone could show a 300HP 1.6 with decent spool. That didn't have an ass ton of expensive headwork.

sorry but before i had very good spool and 300ps to crank at 20 psi

i think that 1.6 is very nice engine and powerfull too.

Wait few days to see my dynos

1.6L miata with a 3076....


http://www.boostedmiata.com/dynos/3076_dyno.jpg

gt3076 has problems with 1.6 to spool but BIG TURBO is running one and his miata is very powerfull.Specially at higer rpm.

At how much psi is this dyno ?

i believe that is 13 psi but it has been awhile since i saw it.

Still waiting on those dyno sheets of a 1.6 spooling a 30r at 4k

Same here...

psi doesn't matter, just augments power band in boost.

He posted that to illustrate the later boost onset.

3076 is too different from 3071. If you dyno a wrong laggy setup maybe you have problems with 3076.

i haven't reason to tell lies. I didn't tell that i have full boost at 4000 i tell that i have very good spool from 4000.

I will post my dyno when i did it and then we can discuss about the power and spool.

I can understand that 1.6 is a european version smaller and strange to you.


Spool is depended from too many other things like compression, ic and tubes, exhaust, external wg etc etc

ps: My car is for drag street use not for trackdays, I have too many good results with my small 1.6 against to many bigger enemys.

:fawk::fawk::fawk::fawk::fawk::fawk::fawk::fawk::f awk::fawk::fawk:

great story Hansel, would read again.

well here's a GT3071 on a stroked 2.0L miata:

the red one here is another 2.0L Stroked miata:

Post your spark/fuel maps, datalogs, and your dyno chart. Not calling absolute BS, but I've driven a 1.6 with a .86 2860RS and it didn't get full boost until well past 4k.

He's not at full boost by 4000.

my gt3071 has A/R 0.50 to compressor and turbine 0.63

housing same with gt2560

I know that 2860rs has very bad spool and very older design than gt30 series.

FWIW...

I am in the process of finishing a long term 1.6 project. Damn 3 year divorce and car being in her name has put a damper on project. Title in my name and moving forward finally!

Here are some details....

3071 with .63 turbine and 4" inlet
BEGI cast manifold with Tial 38mm
3" all the way with wastegate tube running about 20" before entering exhaust, custom job by Corky.

Shitload of head work: +1mm valves, Supertechs strongest double springs & Ti retainers. Full port rework flowing 285 cfm at .400 lift. 274 duration intake & 266 exhaust with .395 lift. Chrysler 300m coils with M&W Pro 12 CDI

ACT pro lite flywheel with an SPEC stage 3+ Aluminum PP that has been modified for more torque holding power. MSM 6 Speed & Rear end 3.63 gears.

I dont expect this to spool till at least 4500rpm due to the agressive cams

^^^ pictures? The 3071 sucks anyways...3076 is the way to go.

Today i get my car from my tuner. I will post more pics tomorrow. Now i just wait to go for tuning to duno.

Sweet...but I think you should plumb up your turbo and wastegate before you head off to the dyno...

man this photo is before one week and was taken during the proccess.

Finally some number .........

Still waiting :( i have an appointment at 2/12 for the dyno. So until then just hope to get a good number

Another Tease!

I hope that's our Dec 2, not Feb 12

This thread gives me blue balls

blue balls ? what do you mean ?

some pics of my car. I still waiting the magic 2/12

See now you're talking out your ass. You clearly said something that is not true. Which is that your big ass 30r turbo is spooled by 4k on a 1.6L.

You did NOT correct that statement or interpret it to us for days. Now you come back in and say "that's not what I meant. I mean its good spool, not full spool":jerkit:
Can you be any more vague?

A 40r car can also say "I have good spool at 4k". It is nowhere near peak pressure but that doesn't matter right?:loser:


Oh well, I knew it was too good to be true. Good thing I didn't hold my breath.

Don't get me wrong, you have a cool setup. Just need to be more specific when you STATE something.

why guys you are too offensive here ? i haven't any reason to tell lies i know my car and i am serius tuning it. No diy manifolds, ecu's and engine builds. I have seen too many 1.6 engines push easily a gt3071 not only the Mazda bp 1.6.

We're not offensive at all:)

When you say something like what you did people get excited. Because its either unheard of, rare, or a very big achievement. So they expect for you to deliver the proof.

And don't compare a miata 1.6 to other 1.6L's. Not the same.

And we're not flaming you. More like disappointed;)

I mean it in the sense that I opened the thread hoping that you had numbers and spool data already. Is true what 18 said, or at least I agree with him. Im anxious to see the result. Dont take everything that is said too serious

this is my first post about spool in this thread.
Where i said about full boost man ? I am not crazy i just sharing opinions to a very usefull forum for me.

The only thing that i can do is to post my dyno and some videos of my car.

I can't believe that a fiat punto 1.6 8v (1993 design) can beat our engines.
I have too many examples for you.Maybe smaller displacements are not too popular to you but believe me are too strong.

ps : 3071 is much quicker to spool than 2876

Why does your NB have a 1.6?

Maybe becouse i am from Greece. ;);););)

Oh I see

well is it a normal B6?
I thought the 1.6 in theeuropean NB's was different and made more power, but maybe Im wrong

So where are the videos??

George they have 1.6 engines there too. The most na's are 1.6 .

I can see a point to 18psi's talking, but he missed the picture of this thread and he insisted for something you never said.
Anyway the 30r sure is a big turbo for the 1.6 but who cares?
In the track or in a street race the 30r will never leave you without spool changing at 7k rpm.

is normally 110hp. bp4w is the code i think

Buffon01 when i finish with my car i will post some videos. I haven't with my previous setup.

Watch out, most of the Miata community is suffering from small turbo syndrome.

There is a reason about it and here in Greece we call it tranny failures.

There is a solution and here in America we call it a 6 speed

But of course, 6speeds for your small turbo syndrome is just all you need.

The ones with the 6 speeds tend to get turbo's on the bigger side

come on guys. Problems are worldwide. But is true that an 6 speed is more expensive and not to stable solution like an rx7 II . Don't forget that you need to change and pinion ring to 3.6 if you go for the 6 speed.

I'm just giving him a hard time:D

You have a very nice setup BTW.

Come on George can't we have some fun here?

Seriously I haven't seen a 6speed failure but if I had chose the 6speed path and meet a failure then I would propably cry my money. Couldnt take such a big risk.

That turbo looks huge in the engine bay, almost as huge as that radiator. I like 18psi was hopeful you would have hard data about spooling larger turbos. I'm also running a 1.6, but with a t28 clone. I'd be stoked to find out i could run something larger and have potential to flow over 300whp with out having to do a 1.8 swap.

BTW I always thought the European 1.6 that was available at the same time as the 1.8 made less hp than the original 1.6 from the NA6 miata's. I've seen articles that refereed to it as detuned. Sort of like the 900cc motor in the Honda 919, vs, the CBR 900.

Have you seen any benefit from that torque damper?
