I got questions regarding these 2 turbos that I have narrowed down to. On daily driving most of the time I am in traffic so will I notice a difference in the 3071 and GT35R if I were to keep the car under 4k most of the time? Boost is one thing once I punch it but what about significant differences between these two if it were below 4k rpm in daily traffic driving? How much more fuel will the 3071 consume compared to the GT35?

Thanks

 

I would say it wouldnt be much different, but that depends. The 30r will spool around 3800 rpm and the 35r more like 4300. I guess you could stay out of boost easier with the 35r, but you could probably do the same with the 30r. The 35r will give you another 50whp though on pump fuel.

Btw I have AMS's 35r in my car so I speak partially from experience.

 

Is your car a daily driver and how do you like and dislike about the GT35R?
How many whp are you making with your GT35R on pump gas? If you dont mind please also list your supporting mods, I am very interested in purchasing a turbo so I need to collect as much info as possible.

Thanks

 

Off boost the car will drive and consume fuel the same so long as they are tuned correctly. Even with the big 35R. I have a 35R on my car and I get 29 MPG on the highway thanks to Martin and O2Feedback on the AEM EMS system.

Have you guy's experimented with the injector phasing in the EMS to get a better MPG?

 

How much whp can you get with GT35 on pump gas with just simple mods like cam gears and cam shafts with safe boost? The gas we get in Taiwan is 98 octane but its about 93 octane in the US. This might be the choice of turbo for me if it really can be driven daily. Which would you recommend for daily driving?

 

Why don't you just get a turbo right inbetween the two (gt30r w/.63 backside) aka 3037

The 35r is perfectly streetable. Off boost it will accelerate like any other 4 banger and then above 3k rpm you will start gradually speeding up until just above 4k where you go into a much steeper power gain. I only have bigger intercooler, 660cc injectors, fuel pump, intake, turbo kit from AMS as well as their exhaust and IC pipes, avcr boost control and safc fuel control. Soon to have dynoflash.

I figure at least 400whp on 93 or 91 octane once it's dynoflashed. I will get more concrete numbers in a week from today.

 

ams correct me if I'm wrong but I read in a thread that you guys made 460-480whp on 93 oct. with the gt-35r

 

You can but you would be pushing the limits of knock. Too much compression at that point. you can fairly safely put down 450 though. I don't have cams, which is why I'm not sure what to expect. Oh and I had to custom route my wastegate dump into my downpipe, which I hope didn't hurt my power output too much. It made my car super quiet though. All the noise from the AMS exhaust was comming from that wastegate.

 

i jsut want to know the major differances between the GT3071R Kit and the GT3076R Kit.... ill be looking for around 400 whp and maybe maxing out at 460whp later on... what are the differances between the two????

 

kcevo, I have and it does make a difference. You should try it out, I am pretty sure you are running big injectors so it will help but try it so you can compair the differences. Start out at zero and ramp up to about 160 degrees at 7k. Be sure to log knock as well. I have never seen it provide negative results to knock only positive but rather safe than sorry.

 

I have seen your posts on the AEM forum and you have had great results. I am using 1000cc's and was going to experiment with it. I was thinking of mirroring the injector phasing that the Eclipse uses in it's startup calibration, have you looked at it?

 

Yes I have looked at the DSM maps and mine is very similar so that should at least get you started (Iam running 850cc injectors). The way I came up with my settings is by monitoring egt's and data logging all fuel knock and timing signals from the EMS, I did this for several days. I did notice that once I ramped up the inj Advance my egt's did increase back up to temps that were closer (but still lower) to what the stock ECU ran when I had it in the car. But the car did seem to handle timing and fuel transistions much better/smoother. Once everything felt good and the maps were sound and looked consistant I decided to keep my map. I have looked at several other maps on DSMs and they run the inj advance map ramped up in some sort of fashion just like the base map for the DSM's.

Hope this helps get you started.
