actualy platinum you dont need to change the pinion it just scales better if you do. Over all i hope i am not the only one who is excited to see your numbers. Dont let these gramar and spelling nazis disuade your progress. Most of them are newbs in disquise.
Also blue balls is when you are on the verge of cumming and you dont repeatedly this will cause a pressure buildup and pain in your testicels. It is a sexual inuendo implying that you are teasing them with seductive things. |
Like I said Tease!

How can you? You live in a cave, eating roots and raping children.
|
Platinum, we are all very interested in your build. We always joke with each other like that on this forum.
You should add Greece to your details so it shows under your name like gianic does. It will help stop misunderstandings. I really like the big turbos. But it looks like you will need a heat shield between the turbo/downpipe and the brake system. The brake reservoir plastic melts easily on our cars. We are all happy to have you here and are very interested in your dyno results. Good luck. |
Wow...that turbo is HUGE!
I have mad respect for your build...and really want to see numbers. I have a feeling I'm going to pull the trigger on some rods soon...and see just what a 1.6L can really do. I caught a deal on a Tbird compressor upgrade over the weekend...and got my water injection working yesterday. Besides our slew of drivetrain problems I don't see why everyone fears big turbos. Having started with a turbo 2 sizes too small I'll never make the same mistake again. |
I don't think its as much people "fearing" them as most just wanting something small and responsive to give the miata a bit of a kick down low and in the midrange to make it a fun daily driver. Everyone knows a car driven daily is much more fun with quick response and a very nice curve compared to one that takes til 5k to really "hit" and then hits so violently you're counter steering for the next 2 minutes:giggle:
That said, I would like to also add: I LOVE BIG TURBO'S:D |
Idk, a lot of the miata community fears bit turbos, or lag in general. Its juts a bunch of old school thinking.
*cough* M.net *cough cough* I dont really see that on here as much. You gotta remeber that these engines dont flow or rev as high as hondas, its common to see 30R's on built 1.8L hondas and 35R's on really serious builds, but our engines dont seem to respond to that big of a turbo quite as well. |
That too. I forgot to mention that.
|
For instance
Mazda B6 with GT3076R at 13psi http://www.boostedmiata.com/dynos/3076_dyno.jpg Honda B16 with GT3076R at 10psi and 18 psi http://i147.photobucket.com/albums/r...blockgsr-1.jpg |
That B6 needs a camshaft that is optimized for the 5000-7000 rpm range. Stock cams are designed for midrange torque, and not where big turbos make their power. Every component should be optimized for operation in the same rpm range if you are trying to get the most out of it. We are limited by some (head design), but others we can change (cams, intake, exhaust system).
|
this dyno is just terrible. First of all a gt3076 at 13 psi is just sleeping.
If you check the maps from garrett you will see that the best perfomance is from 25 psi and up. I told again that gt3076 is much different than a gt3071.Gt3076 is a smaller Gt35. Is ok only if you have a stroker kit, but you need big pressure to push this huge thing. 30psi and up you will have the best perfomance. Gt3071 is very similar with gt2871 but with new design and much better spool. Honda are very strong and nice but i have too many others engines to compare very similar to bp engines.For example Toyota 4a-ge is a very popular 1.6 16v engine that can easily push a gt3071. |
Your seriously teasing us, I've never seen turbo that large on a 4AGE, and I've seen corollas with both 7M, and 2J swaps. Do you know of any other miata's running your setup with number to back up the claim. I'm not saying your wrong, but before I start putting a ton of stuff on ebay to get a different turbo, I'd like to see some results.

yah Im seeing pretty high efficiency around the 10 psi range, so saying the car was not efficient at 13 psi doesnt make a whole lot of sense. What I do see is low efficiency at low flow rates (like those generated by our little engines, lol). Hence the lag, and lack of power. So Im just going to draw this conclusion: Unless youre doing a reeeally serious build, gt3076 = way too big gt3071 = pretty big, learn to brake boost gt2871 = probably the best balance of power to driveability imho |

But it was at altitude. I went back to a dyno after I got home here at sea level with the same exact tune. It was a Dyno Dynamics Dyno. Peak power was measured at 356 HP but the torque crossed the 300 ft-lb mark by 3750 rpm. And the torque curve is way flatter. Altitude added ~500 rpm to the boost threshold and altitude dyno correction applied to a boosted car added about 40hp to the peak hp number it looks to me. Bob |
Thats cool, but I thought we were talking about 1.6's not 1.8's or larger.

My other point. Get more displacement! I ran that same turbo setup on a stock 1.8l with a 99 head it rocked that way too. Boost rise was still smooth and top end power was increasable. I ran a turboed 1.6l for 7 years before upgrading, should have put in the 1.8 from the start. I think the only reason to stick with the 1.6l is if you are building a car for coolness factor more than engine performance. if that were the case I probably wouldn’t bother with a turbo. Id do IRTB,s or something. Bob |
Now I understand, thanks for clarification.

https://www.miataturbo.net/forum/t4097/ This is an mx5 of a very good friend.Believe me is a killer and not too lagy. Is have slower spool than mine i think his boost is full at 5000 rpm and have the older 1.6 that is not too strong like mine.I will phone him to write exactly about his spool and boost. Probably the point is different, maybe we don't care too much about spool becouse we are doing drags only but believe me isn't too big problem.Specially when you get too much power after 5000 rpm you can don't think the slower spool. If i was drifting i had keep my 2560 but in same pressure i dyno my car with 3071 and i had 30hp more than 2560. Most of street races here in Greece are from 2 gear and 50-60km for 400-800 meters. So spool is important some times but never we had problem to the first meters. |

Thanks for the additional info.

Please also post pictures of your car also. Did you use the RX7 transmission also like BIGTURBO? Thanks. We haven't dyno yet the car becouse he is tuning it to the road alone, but when i finished mine we will do to many tests. :P About the transmission, no we haven't the same modification i bought from here an adaptor plate and a rx7 fc II housing from a member. The reason was only the money becouse the modificiation like bigturbo is expensive. I have already post some photos to the previous pages. |
hello to everyone. I cannot understand where is the problem here?? Why so offence to big turbo miata's choices?
And for some guys, the GT3076R ATP turbo at 1.6lt engine fully built and HKS st2 cams is 25psi at 4800. 4800 until 7800 is very nice for drag use. Much better from 2800-4800 with 2554's at BPs. ;) |
I don't think most of the guys here see anything wrong with larger turbo's, most of us want as much power as we can produce with out overpowering the miata chassis. However many of us, do more than just drag race, and a lot of the owners here need a broad range of power. Considering the road races, TT, Auto-Xers, and even the drifters.
So although the idea of the additional power is appealing, the current logic seems to be if you want to run a turbo that size you really need to swap in a 1.8, and to make the most of it you need to build that 1.8. The idea that you were making the power you predicted on a 1.6 appeals to most of us because it could mean we don't do a 1.8 or even an LS1 swap to break 300-350 whp or more in a miata. Well at least this is my opinion on the matter.

I agree with you when you going with larger turbos you can doing only good drags and a litle bit of drift.

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 285CFM @ .400 YOUR ON FUCKING CRACK!!!!!!!! thats what v-tec heads flow, and the shit on miata heads and that at .550 lift. i flowed my fully ported 1mm+ valve 99 head up to .500 lift i got 247 cfm @ 28" of water. no fucking way your 1.6 head is doing that. and if it is...... you have 0 velocity |

Today we start to tune my car. First impressions are very good.We stop at 29 psi because we had problem with the spurg plugs. So i will change them with colder and i will have a better result.So the second dyno is that with the problem. I haven't an opinion to the road yet because here is raining all day.
First dyno at 26 psi Second at 29 psi http://img300.imageshack.us/img300/4...psidyno.th.jpghttp://img300.imageshack.us/img300/5...psidyno.th.jpg |
I think it says 354 horsepower at 7300 rpm on the second chart. Really good numbers. What octane is your fuel and what are you using for ignition coils?

and 337whp at 7240rpm and 38.4 kg of torque at 26psi. I only have the red magnecors and nothing else something special. fuel 100 octane |
Numbers seem low for 29 pounds of boost...

This usually happen at dynapacks |
Just 3 psi's can make really huge difference!
Great output George! |
50 hp difference is extreme between dyno's I think, I know Mustang dynos are around 15% lower than dynojets. My car was dynoed on a dynojet--the same one that the worlds highest hp evo uses.

15% x 300hp = 45hp 15% x 400hp = 60hp Sure does sound plenty possible to me. |

Today we change the spark plugs with ngk 8 platinum and we test the car to 31 psi on the road for fine tuning.
Is just super very good power with very good spool, and of course too difficult to drive it. I spin the 3 first gears with 17'' rims. I can't see the rpms to change because is too fast when accelerate !!! Next step is r888 and flyinmiata butterfly,xyz brakes 330cm 6pistons calipers, maybe and a better suspesion than kayaba, hotbits is very good but i am not sure. So if anyone poor 1.6 wants to taste a gt3071 is just cooooooool !!!! |
wasn't your dyno day yesterday?
I'm waiting to see what kind of numbers you crazy Greeks put up next. |

Greek>Dutch |
at 29 lbs im kinda disapointed but overall its not bad. I am sure you have a few horse left in that corral yet.

approvement of my hp. When we tune with heavy load to dyno we know that the result will be with less hp.If i measure to an other dyno here in Greece i will have more hp for sure.I already have too many examples from other cars of friends. The point is my spool and some guys told that a 1.6 with gt3071 will be the worst think ever.Last thing is that my maps are very safe, so some horses we lost them to save our pocket. :) :) :) |
Would it be possible to see your timing map?
