GT3071R Bolt On Turbo Kit for Mazdaspeed 3

[redrocketz]

my buddy ran 512whp on his stock engine SRT-4 for roughly 10K miles and had no trouble until he got greedy and cranked it up more. And you can make 500awhp on stock bottom end EVO's. AMS does it all the time by us.

 

[ericrapp]

So how about 365 whp, can we have that, on stock internals please!

 

[redrocketz]

with a really good tune possibly if we can get to 330 on a speed6 it isn't out of the realm of possibility.

Nobody ever lists the KA24DE...sigh. Supras can handle ungodly amounts of power on the stock block...

I'd really like to find the limits of our stock block...Who wants to give me money to find out?

30minutes before physics exam...

supra's automatic tran's can handle close to 700hp, lol.

1.8t vw's can handle about 350whp on stock internals.
2.0t fsi motors (JC's mainly) is at about 360whp on his stock block, and thats a 2.0l vs our 2.3l.

I'd like that. What kind of money are we talking about here.

 

[Sierra117]

Money to buy a brand new motor if/when mine blows up...

I really doubt your buddy made that kind of power on an srt4 stock motor for that long unless he stayed off the gas alot of the time or if that was a dyno queen number on nitrous and he was really making about 400 off the bottle. And stock bottom end is not the same as stock top end, and I would hardly say they do that "all the time".

That's because KA's top end cant handle that much power, the bottom end is pretty strong. Don't get me wrong, you can build a strong turbo ka for about 2k, but whats the point, its still not carb legal and an sr20det cost 1,000 and for that extra 1k can make 300whp. Plus, they rev ALOT higher, which is nice for both drifting and road courses in cars with turbo lag.


And the supra is a completely different animal, the most powerful I6 ever built, that and the rb, but it may actually be stronger than the RB.

Wanna make 500whp on a stock engine? get an LSx.

Neither is an SR20DET swap, LOL. And I know someone making 500whp on a stock internal KA24DE with a T04. And revving higher is an excuse for people who don't have torque.

Plenty of people are running their srt's to 500hp+ on the stock block. Those motors are stout man... Seems like they're a dime a dozen these days...

assume all you want but there was no laughing gas on his car just a big old 3076r. I saw the car on the dyno and off he beat the s*** out of that car too. 4 input shafts and 2 trannies before the motor popped.

Almost none of those engines you listed can handle 500hp on the stock block. I also have an sr20det, the most you should run on a stock block on that motor is 350ish whp, which is even sorta pushing it. ej20's can't come close to 500hp on the stock blocks. 4g63 is gonna have crank walk at that power level on a stock block. Hell, even the tt 300zx with its extremely strong 6 cylinder engine can't really handle 500whp, i think scc's blew up in the low 400's. Srt4's also can't handle 500hp on the stock block for a very long time. And that is crank horsepower, no way any of those cars can touch that with whp, like really, it would be a bad idea.

We also aren't talking about 80-100whp over stock, you can make that with bolt on's with this car. they are stating 450 chp, which is like 390whp, about 150whp more than stock. I would be shoked if the engine could handle that much power.

To tell you the truth, I think 400whp in this car is retarded, any fwd car for that matter, you end up with two completely useless gear and one pretty useless gears. But I know alot of people are really into dragging.

no disrespect but i dunno what planet you are from but people are doing 430-450awhp out of the ej20 and ej25(safely) for years, 4g63's have been doing 450-500whp on stock bottom end, talk to buschur and AMS. I've owned a gt30 SR20det GTi-R nissan pulsar 390awhp all day. i've also owned a SRT-4 417whp, current owner has been @ 482 for the past three years...breaking axles left and right and tearing up the 03' tranny but its still going. so as i was saying....all these motors are capable of 500hp and i think everyone else basically agreed with me.

We can do it, there are quite a few speed6's that are over 300+whp with a gt30, times that by 15-20% depending on the power you make and that should equate to somewhere around 330+whp for us. There should be no doubt that we're safe, all i want from this car is 330-360whp. s*** anything over 330 makes the car useless in the first three gears but having that kind of power is a reassurance.

i guess i can't escape the sr vs ka arguments, even on a damn mazda board :-\

there is always going to be a select few people who have ridiculous numbers, and even out of that group, there is a smaller few who have pretty good longevity at those high levels. i find it funny though, when most people just want to have stupid high numbers, when there are guys out there touching 10s with ~400whp. [coughdrivermodcough]

what i am interested in, is to learn more about DI and what it will take for it to sustain a respectable, but not excessive, amount of power. i think 350whp (with torque numbers hovering around 400ft-lbs) is more than enough to propel any MS3 to easy 11 second timeslips (with driver mod), and is perfect for a road course. (note: i like having about 20-30hp more than i need on a road course, allows for some throttle modulation)

+1. On our front driver with our gearing, I would be perfectly happy with around 350 wheel, and 400-410ftlbs. I wouldn't want any more unless I was building the tranny and running slicks to handle it all.

However...I also wouldn't mind going the AMS/Burschur Evo route. Big power numbers with good times.

I agree completely.

Yeah, my point was neither are carb legal, so I don't see the point of a boosted ka, but to each his own.

You have a link of an ej20 making 450 awp on the stock block? Never seen it on a stock block before, never even seen close to it, on a 100% stock block. And stock bottom end, again, is not stock block.

All I remember from a 500whp srt4 is the first video I saw on srtforums when the car went boom about 20 minutes after install. But who knows, I could be wrong,but just about every car with that kind of power has a built motor that I have seen on those forums. If your gonna spend money to go that big, might as well do it right.

worst. math. ever. 300/10 (10%) = 30hp. At 15/20%, that'd be 45-60hp.

350whp+

we'll see.

come here to michigan and i'll show you six or seven without flinching.

and as far as your carb thing too, not every state in the country has carb laws that are enforced. here i could no cats all day for the next ten years and not worry about emissions and i know that a lot of states have different rules and regulations that allow for newer cars to not get tested for 5 years. but anyway continue....i'm sure you had a point some where.
