Misc Turbo Sizes and Flows

Turbo flows and sizes information, random copy paste from the web. If you do have anything to be taken down, please do let me know.

Evo 8 TD05 Turbo - (360HP) Stock Evo 8 TD05-16G with 9.8 exhaust housing
Evo 8 TD05 Turbo - (380HP) TD05-16G with 10.5 exhaust housing
Evo 8 20G Turbo - (415HP) Upgraded TD05 with 20g compressor wheel and 10.5 exhaust housing
Evo 9 TD05 Turbo - (390HP) Stock Evo 9 TD05H-16G with 10.5 exhaust housing
Evo 9 20G Turbo - (425HP) Stock Evo 9 turbo with the 20G compressor wheel

Forced Performance have awsome Evo 9 based Turbos Available:

FP White (425HP) capable
Evo 9 based Turbo with:
Larger HTA 68mm Compressor Wheel

FP Green (475HP) capable
Larger FP 47lbs Compressor Wheel
Larger FP designed Turbine Wheel

FP RED (550HP) capable
Larger FP Red HTA Compressor Wheel
Larger FP designed Turbine Wheel

Also the 600HP+ FP Black and the new FP GREEN 73HTA Turbo (seems to be hot pick for a 500HP street turbo).

Also look at the BBK turbos, they seem quite popular.

nb. the stock turbo's need high boost and race fuel with suporting mods to make these kind of power figures... (But it is possible.)


GT3071R - (450HP) Boost is seen 700 - 1000 rpm earlier than the
GT3037S and only 200-300 later than stock. needs less boost than the FP Green to make the same power levels.

GT3076S - (525HP) This "benchmark" turbo, used my many a kitmaker, makes excellent power but spool-up does suffer about 1000rpm later than stock.

GT35R - (650HP) Most talked about Turbo - excellent race Turbo used by those that want big power an low ETs

and for 600HP+ = GT35R, PTE3562, PTE6262, GT4088R, etc...  




So I've owned a lot of T3-T4 Turbo's of different specs and from experiance I can tell you that depending on the combination of compressor and exhaust wheels on std frame T3/T4 with a T3 .63 Turbine housing and a T04E Compressor side they can hit peak poost anywhere between 3000 and 5000rpm for a non ball-bearing Turbo...

I have been curious to see where the mordern day variants of these T3-T4's spool on a 2.3L EVO with the .63 Exhaust housing:

GT3071R - AMS say 3300-3400rpm on a 2.3L Stroker, with around 3800rpm on the stock block 2L. [450HP capable Turbo]

GT3076R - Evo_M owners claim 3800rpm on a 2.3L Stroker with about 4000-4200rpm on the stock block 2L depending on supporting mods... [500HP capable Turbo]

GT35R - 4100-4300rpm on a 2.3L Stroker and on the stock block 2L depending on supporting mods as high as 4500-4900rpm... [600HP capable Turbo]



On the whole .63 vs .82 Hotside issue: 

from EVO M
The 50trim is larger that the 3071 and will flow 49lbs of air, the 71R a bit less than that.

The 76 will flow 52 pounds of air and the 35R 62 pounds.

The 50trim spools up around 4000 when no-ball bearing but about 200-400rpm sooner when dualbb,

Ive seen more say 400rpm sooner, RNR sells both and they claim a 400rpm quicker spool.

Also, RNR made 389hp at 21psi on 91 and 423hp on 93 without alcohol injection. So it seems it spools faster than the 3071 and makes more power...

it can make almost as much HP as the 3076 but with faster spoolup and for a pump gas turbo I think the 50trim is better,

if your going to run race gas all the time or alcohol then maybe the 3076 would work better for you.

One more thing, a TurboTrix customer, REZ90, made 480hp with the 50trim although I dont know the supporting mods.

Also, a 3037 is capable of about 520hp, the 50trim about 490hp(good tune, race gas) but faster spool and me running pump gas on a daily basis in my mind make the 50trim better.

If any of this is wrong, someone correct me, a turbo isnt cheap and I dont want to buy the wrong one.

Smogrunner, sorry, I never saw this post. Anyone who wants my attention in a post just send me a PM with a link and I'll be glad to stop by.

First, if you use the Tial or Garrett ported shroud compressor covers you will NOT experience any surging with the HTA35r.

Next, the .63 housing works very good with the 35r's. Depending on the build we are doing we will sometimes use the .82 housing. I have now tested a few different header designs and tested 4-5 different turbine housings with the HTA35r.

Overall I'd say the .63 housing works the best and a 2.5" outlet with a 2.5" 02 housing doesn't seem to hurt the power at all compared to the 3" stuff. The 3" does however make fabricating the housing, nicely, in one piece much easier.

It was said that most of the charts posted from us are on the .82 housing. That could seem true simpy because my car has a ton of charts posted BUT there are some kick ass charts posted with the .63 housing too. We've made 520 whp here on the .63 housing on 93 octane. Best ever was on Peter's car at 547 whp on the .82 but the car is also set up just like mine with nothing left out.

The .82 should make another 30-50 whp on a full tilt car than the .63. The difference in spool as dave said should be about 2-300 rpm sooner at lower boost levels, although I would venture a guess that the difference between spool times to make 30 psi would be more considerable in the 4-500 rpm range.
