GT3071R Bolt On Turbo Kit for Mazdaspeed 3

I dont know why everyone is getting their panties in a bunch over the ******* rods. Its this simple, rods will go through the block when you get detonation. These are DI, have a higher lean rate and there isnt one single problem the MS3 has experience that the MS6 has. So **** it, time to prove the naysayers wrong. If a Lightning can hold 500hp all day long at the wheels with a big ass Kenne Bell blower and tune with its sorry ass weak rods, this engine isnt going to have a problem. As long as you got that MRLILGUY fuel pump and keep this boost below 20 on that monster, you guys are going to hit 400hp with little effort. For those who are ultimately paranoid, add some methanol.

The drivetrain on the other hand, is going to be your weak point. Get a beefy clutch and go easy on the trans from gears 1-2 & 3. From what ive seen of the internals on this trans, the synchros look quite weak from 1-3, but get beefier from 4-6.

So if you run stock boost and have no adjustability in tuning (stock ECU)...race gas is useless...

Basically, the stock ECU will not take advantage of the higher octane gas...right?

Race gas isnt usless here! The higher octane will prevent the on-set of detonation. ***If you were to pick up knock
 
Sweet, another race gas discussion. And I'm not being sarcastic there, I really do like race gas discussions, lol. I dunno why. maybe the same reason I like red heads over blondes, and LOVE red heads over blondes.

Sans tuning, race gas won't do anything for you. Its too bad most people don't know that. I've run into people who claim with stock 15 second cars they've been able to run 13s on 110 octane, lol.

im not saying it will increase HP!

im saying it helps make for cooler combustion and less detonation which is always better IMO..... The HP comes from the ability to run more boost due to the higher octane.
 
I was always told by my tuner (Jorge from P&L) that running race gas ona pump gas map will not net you any more HP and it will take a toll on your bearings. He said something to the fact that race gas and pump gas burn at different rates and running race gas on a pump gas map will result in your bearing's getting pounded. I dont know how to explain it very well, but they way he explained it made sence.

Jorge is a pretty smart guy. I would listen to what he says, now on that note mixing race gas and regular together for a few runs down the track isn't going to do anything harmful to your engine. P&L is where we took Jason's car to tune it.

Race gas net's in HP due to the fact that your able to run higher boost due to the octane jump having some sense that detonation will hold off due to the cooler burn (not always ofcourse).

I know of only one MS3 with a bown motor and that was a manufacturing defect. It's funny how you make a statement like that on your First Post.

Oh, I'm sorry - I don't live on the boards, nor do I get all my info from THIS board. Christ the ************ crowd pulled the same s*** when I offer up info that doesn't jive with the popular opinion.

I've personally met 2 MS3 owners who've blown their motors from going to a larger turbo with improper tuning. One guy rebuilt his motor in Stamford CT and is still running the 30R but with stock-ish boost. You act like if you didn't see/read it here it hasn't happened...? Maybe you guys chat about it here but its actually happening "out there". And by blown, I mean high EGT, melt, not hole-in-block. Its a fueling/timing issue.

BTW, nice board ;)

Oh, I knew what you were saying. I was just saying that some people don't get it.

Jorge is pretty much that man! He tuned my STi like 5 times with 5 different setups (second)

He will be tuning my MS3 as well, if he decides to get the tuning software.

Or more directly if the ECU isn't pulling timing due to knock, it'l net some power.
