GT3071R Bolt On Turbo Kit for Mazdaspeed 3

Has anyone successfully installed the new turbo yet, and if so what kind of gains are you seeing?

i should have mine this week, installed over the weekend, i'll be sure to let you know the butt dyno, but not really, because my new intercooler wont be here until the following week :(

will this work for the Speed 6 as well?

I don't see why it wouldnt, but I cant make you any guarantees.
 
When is your turbo supposed to arrive? This week? I never heard if they shipped or not.

Well Ive got to wait until the manifold gets here too, before I start ripping stuff off. I have 2 days scheduled at my shop the 10th and 11th to get this all on and tuned. Maybe you'll beat me to it.
 
with the current fueling available... i see mid to high 300's just slapping on a bigger turbo and manifold.

I agree as well but tunning has a big factor....depends on how agressive u tune the car....when i had my GTO i had two maps one was 385whp and the crazy agressive tune was 410whp.....The 410whp was race map only there was no way i would drive that car daily like that...idle was crazy and timing was advanced and that map was a gas hog....
 
criscecc something he put the turbo on and went out for a run and got maybe a block or 2 before it went zoom zoom boom on his ass then I built him a motor.
 
must be a MS6 ??? i never heard about it. did he have a fuel pump upgrade ??
i am a strong believer of "no tuning needed" on this car. its just boost. feed it fuel and all is good.

And here your saying put a larger turbo on and dont tune for it, hmmmm. (uhm)
 
yep i would. with a cdfp and intank pump. not without either one. why would just a new turbo require the ecu to be modded ? it is just creating boost right ? the engines sensors will see all the correct info right ? the will read the MAF and o2's and adjust as needed... just like it does on my car with
20psi. the issue arises when yo start maxing out your MAF or running out of fuel. i am willing to bet that member went lean and blew up. with a proper fuel system it would not have happened. ods are he held big boost up top and ran out of fuel. i'm sure it didnt happen at low-mid RPM. if anythin the car will run richer in the mid range beacuse the big turbo will spool up slower.

everything you know or think you know means nothing on this car. its not a WRX. this is by far the best ECU i have ever dealt with.
 
I see your view, and I have mine I guess. Thanks for not getting all pissy and start getting a sandy vagina like some would.
 
I've decided that I'm probably not going to run a bigger turbo in this car as I'm going to make this a daily driver. I am on the other hand looking for a weekender and have come across a balls to the wall clean S13 240 making about 410WHP. GT28, SR20DET with head work, bottom end, and a lot of other goodies. I just think with that type of power in a speed 3 it's going to be hard to get it to the ground. Also, the amount I'm going to have to spend on it will be close to what I'll pay for another car and I know I won't get nearly what I put into it down the road.

i have spoken to chris a while back, he did mention that he didnt even romp on it and it basically just blew in two blocks. i've done my datalogs, our injectors are sitting at 42-45% dutycycle so we have fuel. Fine tuning will help, but simple mechanics...with the fuel we have available this car WILL put 330+ on the ground without a tune(praying the ECU lets us). I've heard the term "pig rich" since ive been screwing with cars for 12yrs now but by far the MS3 takes the cake for the biggest fuel hog i've ever owned.

on a side note, Chris' car would be the sickest in the Speed community hands down! but this friggin ECU is a joke, i really hope some vendor like AEM, Haltec or nemesis takes a look at him and develops a full or inline standalone for his car.....too much work to go to waste. i'd love to have a 5-600awhp monster.

i was under the impression that ATP put a bigger spring rate wastegate on his turbo on accident

if you're driving a big turbo car around the block, not romping on it, you'd be out of boost, which means no pressure and next to no chance of blowing the block.

maybe he forgot to put oil in? i dont know, but i don't believe that he was just cruising down the street and "pop". no boost on a 3071/3076r vs no boost on a k04 = just that, no boost, no difference.

42-45% dutycycle is just about maxed out on a direct injection engine. You can only inject during intake and compression, so 50% is all you get. (freak)
