From what I've gathered over the last two year s the kit works best with a GT3071R Turbo in a .63 config.

Anything bigger and it gets too laggy...

Some guys say teh 35R with the .82 housings don'y even spool..

.

 

uhhhhhhhh 35 r and have a good day.....



seriously, once you go 35 r you never look back.

 

Ok...great. but that is NOT for everyone. If someone is using the EVo as a daily driver and running on 91 octane (no meth), meaning that PSI should not be above 23 PSI with stock internals and probably an HKS 272 CAM update a 35R turbo would NOT be the right turbo for that setup. It WOULD be way to laggy for light to light racing and with only 23 PSI I dont think the thing would ever fully spool up... Correct me if I'm wrong.

 

You are correct. A 35R is a race gas turbo. It sucks on anything less than 100 octane. It's perfect for leaded gas, meth injection, e-85. It begins life over 25 psi.

A nice hybrid is the 3576 with race gas if you have a 2.0.

Pump gas turbos imo are FP's, 3071, 3076 for the Evo.

Pick the fuel, then pick the turbo.

 

wow.... i was just trying to put you in the wrong path.........



goood luck.



do what ever the HEll you wanna do.

*race light to light*

 

Some of those statements don't seem entirely accurate, maybe a little backwards.

It's true that 35R's do great on race gas, but they certainly don't perform poorly on pump, since they can move a lot of air without heating it up as much as a smaller turbo. Naturally, as you said, with this much air, race gas is still highly beneficial, but not as "necessary" to make good use of it, like with a Red or Green.

FP Green and Red don't do badly on pump either, but for the inverse of the reason I mentioned above, don't really wake up until they are on higher boost, and for this reason perform best with race gas, meth, E85.

For pump gas, what about a 50 trim? With the popularity of the Green, especially per dollar, the 50trim has become a bit forgotten, but there is a great reason this has been considered THE pump gas turbo long before the Green existed.

 

The 35 R makes maybe 25 whp more on pump but lags at least 500 rpm compared with 3076. I've run both of them back to back on pump and hated the 35R lag. IMO, you can't run it safely (on a road course) past 24 psi on pump, so you may as well take the quick spool of the smaller turbos.

I think you may have misunderstood what I said about the FP's. From what I've seen, they both do great on pump gas, but of course all of them, including the stock turbo, do better on race gas - more boost AND timing.

I'll take the low end torque of the smaller turbos any day on pump.

 

I think for spoolup and transient response theres no dispute - nothing beats the factory Twin Scroll TD05 Set-ups...

But the limitation is if you are chasing HP numbers then you need Racegas, Meth or E85 due to the performance window of the stock frame Turbo's, they do generate a lot of heat at the boost levels required for them to shine...

For similar power on pump gas at 22/23psi the 50trim, 3071 & 3076 are the turbo's of choice...

With the 3076 already being signifacantly more laggy than the 50Trim and 3071; so without a doubt if you want to steer clear of lag the 35R is not everyones cup of tea...

Id say an FP green is better then both a 3071 and 76 spools faster good power. The red is also a nice turbo flowing about 56-60lbs per minute making more power then a green. If your looking to big turbo it then do a hta35R dont even waste ur time with the 30R's

 

What power does a Green make at 22psi on 91 Oct pump gas?


Thanks

my buddys evo at 23psi 93 octane made about 365-370

 

thats really not all tht impresive if he's only making that much power AND he has an upgraded turbo, in fact, i would fire my tuner if i was only making 365-370 on a bigger turbo. (this is assuming he has full bolt ons)

 

If I had to choose between the 3071 and the 3076, I'd go with the 3076. I don't much like the 3071 as it really flows no more air than the better bolton turbos, such as the FP Green. However, both the 3071 and the 3076 are considerably laggier than the Green.

As far as bolton turbos, in addition to the Green, there are the relatively untested FP White and FP Red turbos. The Red flows more air than even the 3076, and is a bit laggier than the Green.

An HTA 3076 on pump/alky will most likely lay down better numbers than a Green on alky. However, the 3076 will be laggier, and if you're gonna induce more lag into the equation, then you may as well step up to an HTA 35.

In essence I agree with Flyin Evo 2 in post #38. The HTA 35 on straight pump will probably put down at least as much power as the 3076 on pump/alky, if not more. Buschur was running 28-30 PSI on 93 octane when testing the HTA 35. So, 26-27.5 PSI on 91 seems doable with a good tune.

So, either go Green on pump/alky or step up to the HTA 35 on straight pump.

3071 > Green on PUMP GAS with full boltons? (cams, intercooler, piping, injectors, fuel pump etc.)

I'm only interested in pump gas and besides the Green I'm curious about the 3071 - the 20Gs (mainly the FP White, Green and Red) seem to be the most popular first step up from the stock turbo in recent times but the 3071s used to be very highly spoken of.

APT were/are calling it a "450hp" kit; whatever that means, at least this would seem to indicate comparable power potential to a Green on pump gas.

Seeing as FP turbos seem to be really tricky to actually get a hold of just looking into options - curious if anyone's running a 3071 these days and has some pump gas numbers for it?

Anyone running a 3071 out there?

35=lag=one trick pony=no thanks. IMHO of course. If I wanted a drag car I'd have gone v8 domestic. I prefer cars that are more - ah - multidimensional that a straight line :-D

 

The 3071 cannot hold a candle to the Green on pumpgas. There is no ATP 3071 kit that'll put out 450hp on pump gas. A good 3071 kit may have a slight edge over a Green on race gas, but on the street the Green is a way better turbo than the 3071, especially on pump.

The Red is most definitely a way better turbo than the 3071. Only people who can't read, can't drive or are otherwise malinformed would buy a 3071 instead of a Red. The current street turbo choice is between the three FP boltons(Red, White, or Green). The 3071 is no longer a viable option.
