Mazdaspeed3/Mazdaspeed6 + MBC + ATP FCD = BOOMM.....
gt3076r runing as of 9-28-07

yes im a noob i have no idea what im talking about im sure your extensive bolt on experience is far beyond my experience. good job with your exhaust im sure it benefits longevity, reliability, and power better than a front mount or even a better top mount ever could, or a tune.

i didn't mean it as an insult, i toss that word around. and i will benefit from longevity, reliability, and power 
ha!

my point was and still is, people are going down the wrong modding path and paying for it, then everyone is crying wolf, "this guy threw a rod with a MBC and a TBE! THESE MOTORS SUCK!" That's what happens when you have a stock turbo as small as the k04 working over time with an inneficient intercooler. The motor is not the weak point here at all, people just need to start with safety mods, not do them later. that is my point and obviously it is not said enough around here because i still see people with boost controllers as their only mods.

i see your point, but not everyone here is going down this 'wrong path'. in fact only a few have compared to the number of speeds still safely running out there. but the motor is a weak point! i mean look at the thread your posting on..he had all this stuff you speak of..a tune and a FMIC. he still popped, it will just happen when you reach a certain power output on stock internals..always.

and before anything is said about his modding path being wrong! we don't really know the limit of these stock blocks, so i give props and thanks to mike for blowing his motor before i blew mine. now i know what mod path to go with, so i don't BOOm too. but the limits have to be pushed before ppl know where is a safe place to stop modding, without tearing your block apart for internals.

what kind of logic is this? So if you put an mbc and fcd and run the same boost as stock or 1 more psi your gonna see boom? I dont think so. Unless you turn the boost up alot.
Don't forget....... mike also had the gt3076r..... I'm willing to be even with a tune he was making slightly more power than he was with the stock turbo on it and wasn't turning up his boost yet. I think his boost was at 14 psi or something?
You know whom I haven't heard from in a while? I'm gonna have to go back over to the other mazda6 board........ p5freek. He has a sponsorship and has practically ALL the mods on the car, and I know he has the gt3076. I'm gonna see if that dude is still running strong.
^ + 1 I agree

I believe he is selling his car and wants to get an EVO or STI
Man I love the STi, I've got an 05. World Rally Blue with Gold Rims. One of my toys....meh heh
I guess my car is due to blow any moment
meh, 15K on this set up and fine
maybe use this revised formula....
MS3/MS6 + MBC + ATP F/C/D + know WTF you are doing = everything A-OK

Look....Im not trying to be a dick.....but.....Your on borrowed time my friend....but what do I know? I dont hang out at PG (all the damn time) or never talked to any other tuners about that so Ill just sit back and enjory the show.....(2thumbs)

I'm not trying to be a dick either but we can disagree - thats fine
so what is the difference between my running 15-16 psi (pre FMIC) with my set up vs.
running 15.5 but spiking to 19-20 on the factory boost control solenoid?
I'm sorry, it makes no sense
if some joe schmoe dip ship is throwing on a MBC/ATP just to crank up the boost to 20 or so thinking you'll have a rocket, well yeah....your formula for disaster is right on target
Mikey boy.......factory boost is set at 15.6 constant, it'll spike to 18 for maybe a second but doesn't stay there....... 18 psi constant on a bigger turbo is flowing more air than the factory turbo on 15.6 psi. Which is why I said I believe you were making more power with the gt3076 than you were with your stock turbo, and the internals couldn't handle that extra power.

good luck, the sti has a POS stock motor just like the speed 6 and the evo trannies are garbage. My fried has a 300whp evo and had to replace his stock trans with a $5000 shep trans and he was under 10,000 miles on the car. the shep trans just broke nd theres no warranty so now he's selling his evo.
something must be wrong, because they have evo's out there with 1000 whp...... hell I even have a magazine from import tuner with 3 evos doing 1000 or more to the wheels and boosting over 35 psi each (one is 38, one is 46 and the other is 50, they were basically doing a test to see which one would blow up first......)
the EVO motors are stout..... not sure about the trannies.....

All signs of failure are pointing to the darn mechanical fuel pump. It looks like the stock one runs out of flow at the upper RPM's (possibly why the throttle plate is closed at those RPM's by the stock ECU.)
The upgraded pumps now coming into the market are showing signs of letting even the stock ECU keep the throttle open, with everything else being stock. Imagine if you were showing good AFR's (if not quite a bit rich), but suddenly the stock mech. pump ran out of juice, and the change was nearly instant compared to the demands of 18psi+ at high RPM. If this "perfect storm of leanness" came about, I'd certainly see your engine having trouble. It is possible that the AFR's showed good, but in a near instant you went full lean due to the pump running out of flow.
Obviously I'm unable to prove this at the time, but I think this is out Achilles heel. If it is, then great improvement in durability and performance could be achieved just from a simple bolt-on swap of the pump. Time will tell if I'm right, but I have a strong hunch that this is some of the cause. After all, it is one of the best known bottlenecks of the MZR DISI 2.3 engine.
Thoughts?
