Whats the most boost that the stock

[speedfrk]

The fact is that with proper tuning and engine management these motors can handle 12 psi or more and I would say 200 -225 hp to the wheels . IF ITS DONE RIGHT. This is the answer to the orginal post

Don't be cheap, get forged internals - that was my mistake. Well that and not listening to everyone who told me to turn the boost down.

Thanks thats the point I was tryin to make.......

You guys cant even compare the t-3 setup. not to mention I was speaking of well tuned setups but yes your right . in a poorly tuned car with no engine managment or non msp car setup with a t-3 not properly tuned , or a car that has detonation problems you probably should not even add any boost . leave it at stock. your internals will fail .sorry Meant to qlarify that for you .

I do believe we have forged rods and crank shaft . I dont have any info on the pistons though . I think upgrading the rod bolts would be wise before pushing 10-12 psi . at a minimum thats after fuel & timing engine management.

every protege has a forged crank

the engine is, with minor exceptions like the oil cooler, the same as every 2.0 in every protege5, ES sedan and base model 626. no forged pistons, no forged rods.

Hey 14lbs does this mean you will be changing this to read.

I have pictures of stock rods next to the pauter rods . The stock rods are forged but not race quality rods . The weakest points are the pistons and rod bolts . but oh yeah I want some aftermarket forged rods and pistons Dont get me wrong.

What was it you said gave Out ???? I didnt hear that? oH yeah 14lbs did you say your what cracked? oh pistons and rod bolts ?

9 psi on a t3 is probaby roughly 11psi on a t25, which means too much without knowing what's going on in your engine, which is the important point.

Well that and not listening to everyone who told me to turn the boost down.

that is the key to this statement

and seriously that information that i said above is a bare minimum of what you should know about your system when messing with your engine. an autometer blinky light meter and a boost gauge are not the only things you need.

my speed is bone stock except for gas, oil, rear suspension bushing, my winter wheels and tires, the windshield that got cracked, and the ecu reflash.
i'm not in the race scene, i'm in the tuning scene. been there since before i could drive 5 years ago and have been learning ever since. racing doesn't really interest me that much, building motors does.

if you plan to up the boost, know what you're doing and be prepared to deal with the consequences, not cop out and claim it on warranty. our internals do what they were meant to do just fine. expecting to run almost double the boost they were intended to without taking the proper precautions is assanine and it's not the weak internals fault they broke, it's the weak user's fault.

so to answer the original question, the internals will outlast the fuel system. if you detonate, don't expect your internals to last long, as 14lbs proved. learn what is going on inside your engine and you will know how much you can turn up the boost. as a general guide, 8-9psi will probably be safe, but knowledge is the key

no i said piston cracked.....get it rite kid.........

 

[speedfrk]

Sorry that right the t-3 setup broke his rod bolts and you cracked your piston. And mine are still in one piece . just to clarify for everyone whats going on here. and trust me your the KID here.

I hope everyone doesnt take me too seriously here . just like to have fun and argue my opnion once in a while . dont take these remarks as personal attacks . All in good ol posting war fashion.

there's so much mis-information on just the first page, i'm not even going to attempt to clear anything up. my advice is quit being a pussy and figure out how much boost you can run on your own.

and the easiest way to find that out is to blow and engine, come on here and say 'MAZDA SUX ME BILDS SHITT ENGANS. WTF EVO8. "

 

[low_psi]

haha, so true.

hey i blew 1. didnt say it sucks .but people be bsn on this forum.

last time i told someone on this forum that I blew my engine I was accused of bs'n

yes, because thats something that never happened that you'd want to brag about
