I went with the AMS 3071

If I ever upgrade, it will be straight to the gt35r ...

l8r)

 

ill post my results as soon as my WR comes and gets installed since the tuning method thats done on my car is the piggyback way.but im currently looking into getting a water injection kit for it and the ecutek flash as soon as everything gets sorted. my set up is pretty much like a vishnu stage 1++ but w/o the cam gears and running 264 cams.

 

Cool, you tuned that thing yet? Let me know what kind of numbers you put down with your mods(not sure of what they are?????)

Ive been tossing up between those 2 30r turbos....and i just don't think the 3071 will make the power i need/want. Maybe you can change my feelings on that?

 

This is for sharing info only....
I had no intension of putting an aftermarket turbo on my car however, I did buy the WR. I have a UTEC with a Tanabe 2.75" dp that was base-tuned with a slipping stock clutch by TTR to 20.5 psi max and later changed out the clutch. The car has stock cams, fuel pump, injectors, using the stock airbox, cat, and catback exhaust.
I installed the WR with a Cusco intake pipe (stock airbox and paper filter) and Helix hard pipes. After taking a short drive and checking for leaks, the wife and I went for a ride. I was impressed by the way it reacted but said nothing. The wife turned to me and said "wow, there is a lot more power" at that point I had only taken it to about 3/4 throttle.
I jumped on the parkway and punched it, she turned to me and said "damn".
It has not been retuned for the WR and will have Tomei 260 procams, 660 Densos, and a 255 pump before it gets a flash, and alky before the UTEC gets the full tune and dyno.

 

Shot me a PM and I will dicuss this further. No need to go OT any more in the WR thread. BTW, the kit was from a big EVOM vendor and was tested with the two turbos.

 

if that was my wife she would be like"where's the cops when you need them" either that "ill go sleep now so wake me up when we get home"

but back on topic so are you still runnin 20.5 psi with the WR now with the same tune?

 

3071 turbo is far superior turbo than 3076 period. Call Garret and they will tell you the same thing they told me directly. Lets not bring ATP into the subject as this been covered 100 times and you just need to search. ATP has a great kit no questions. I went back to stocker to be a smooth as possible and knowing that I cant afford any lag (NONE) at the track. GT35 at the track will be total disaster. The fasts track I been to was Watkins Glen and I believe that its one of the fastest tracks in the US and I cant imagine a GT35 on it as it will lag and it wont be smooth at all. I say for drag race go and get the Gt35 and for track use stay with stocker and don’t even bother with any other turbo including the WR. I say 330~350WHP on pump is plenty for me on the track and when I see you there with your 3076 I promise you will see my tail light .

 

Ok, sounds like you got lots of seat time

First, i never said i wanted to dominate in either racing venue....i want to have a car that is a pretty fast drag car(what i do most) while not giving up TOO much on the road course(my favorite hobby, but it costs too much to do it 2 or 3 times a month).

I have seen waaay more good things from 3076 kits than 3071 kits as far as power goes. Ive been in a few 3076 cars and was impressed, can't say ive been in a 3071(other than 1 atp car) car but have read either so so things from people, or nothing at all....haven't noticed it to be the more popular 30r turbo. Id like to see some experienced posts from people who had the 3071 kit(not ATP, because it sucks *****).

 

please keep me posted guys or just create a new thread

 

I understand and I have had the same goals for quite some time. The comment of the cold air in reserve having to be a 35R is close to being solved or at least we are now offered a few choices. This has to do with choosing the proper pressure ratio turbo (one with its efficiency islands that are a best fit for the VE of the 4G63 and the limits of pump gas) So far we can max out pump gas with a 35R (345-360 CA 91 DD) with lag, a 3071 (335-355 DD CA 91)with some lag, and hopefully now this turbo. If it is able to follow the 3071 up top and peak HP between 315-335 DD CA 91 while keeping stocklike spool it will be the missing link.

To the guy that was asking how the 3071 outshines a 3037 on pumpgas its because of the pressure ratio of the turbo and the VE of the engine to get it there. Such as a 3071 is more efficient (blows denser colder air) at low PSI than the 3037/76 which suprisingly is less efficient than when its in the high 20s psi.

Thanks for the kudos Al, and if some of you are wondering about the past we have been on better terms for quite some time- so our friendliness is nothing too suprising for you troublemakers . Al looks like he might be the first major tuner to dyno one of these next week so we all will be awaiting his impressions.

3071 compressor map included, notice the highest efficiency islands at a low pressure ratio at the expense of outright flow at high pressure ratios

 

I have it on the stage 2. Its great on pumpgas 336 DD CA 91 on a plain Jane stage 1+ car, staggard cams stock FMIC thats thrashed. I have a feeling that the 3071 will be the goto turbo for guys that have upgraded turbokits and the fun has worn off running a racegas turbo on their daily drivers. The 30/35 is amazing for the event specific car but a lot of people realize that they "Thought they wanted a big turbo" while regretting the fun they used to have in their stock turbod cars. This is were the 3071 and hopefully the WR will come in.

 

I never said anything about outshining on pump gas.....if i wanted a pump gas only turbo, i would look no further than the WR(i am still considering it). I want one that can hold its own on pump gas but be deadly with alky or c16.

I don't want a laggy 35r because it doesn't suit me, i don't think the 3071 can push the power with alky or race gas that i want(but it might, idk). If i can see 475whp or more on the 3071 with pump and alky or race gas, then im sold(other than ATPs CRAP)....if not, i believe the 37/76 is for me.

who knows

 

Basically Dave, what i want is to be able to turn the juice up to shut someone up at the drag strip, while still being able to wax *** on the hwy where the zoh's seem to lurk. Oh, all the while having a trackable car on a road course.

I want it all, in one turbo(the stocker does't quite get the job done on the hwy or the strip). Maybe the 3071 is for me, but i haven't seen enough from it at the strip on high octane to pull me that way.

You dyno your on race fuel? 330 is nice on pump, but id rather see 350-360(DD numbers of course)

although im running alky, i want a 400whp capable pump gas turbo(dynojet). But, from what you say, the 3071 might can be there.... im also on stock intercooler and plan to stay that way.

 

i was looking for the same thing, it was a hard decision, but in the end i chose the 3076 over the 35r due to the fact the i will never run race gas and i live in an area that is 6000ft above sea level. never really considered the 3071 because i did not find any results on this forum that would make me choose it.

 

I bet the WR will get you to 400 whp on a DJ. It will be interesting to see some track times with these to see what they'll do on race gas. Tony and I are trying to go to the track in the next few weeks. He's running the usual upgrades plus alky and a WR. I've driven his car and I'll bet it will run 11.9 to 12.0 on pump before the alky tune. I'm wondering if he can hit 118-122 and maybe 11.3 or so with race gas and more boost. We'll keep everyone posted.
