New Turbocharger!!

[hello2000]

I am in the market for a new turbocharger. Help me pick from this list.
Thanks (uhm)

[KyRaceFan]

theres no list.
do you have a built motor, more fuel, and engine management?
Edit: The gt28rs is probably the best turbo there.. more power and same spool.
I hope you realize you alraedy have a gt25 on your MSP

Dont waste your money on a bigger turbo until youve got all of the above...
Also take in mind you may need a new manifold and downpipe..



edit 2: i voted gt25, because you dont need a bigger turbo.

[hello2000]

I have about $6,000 to spend on my MSP. I don't know much more about this stuff than the average person. My uncle owns his own shop and knows quite a bit about this stuff. He told me he was going to replace the ECU in my car for better fuel management.

Dont wanna be rude, but you dont need a fast car unless you can fix it and tune it yourself.


but anyways, with that kinda cash to throw at it

we have a regular t25 turbo with a upgraded bb center section..its not a gt25....this has been beatin like a dead horse and was finally put to rest....on topic.......i would upgrade ur stock turbo to a "big28" and have fun...easily over 300whp and cheap too :)

[jersey_emt]

The turbo should be the last thing on your list to modify. A lot can be done with this stock turbo. It can push out enough extra power to rip the stock rods to shreds even with good tuning.

I 2nd every part that was listed by KyRaceFan.

:rofl:

definately.
Then again, i hope he buys a boost gauge before he puts on a boost controller (dark)

t3/t04 all the way!!! the t28 is a great turbo for its price but t3/t04 spools up quicker and pound for pound gives way better gains. If you had a t3/t04 on a msp at all stock setting it would be about 40 horse more..

[Turbo Matty P]

true, but boost cut is boost cut. Doesn't matter what a guage tells you. If you can turn it up more without hitting boost cut why does it matter what the guage says?? We know that turbo doesn't put out massive power. I was driving my car for weeks without a boost guage and it ran fine....except rare occassions when it would be cold out or so. My problem happened when it got on the dyno nad threw the "random multiple misfires" CEL. That was the end of my msp.

UI swear all day by the T3/T4, but I've heard great things about that GT28R for 2.0L or less motors.

The car has enough stock fuel to be safe until 12psi, maybe 13 or 14 on race gas. The rods cant handle detonation. If you ran unlonwn boostpsi for a few weeks, your car was a timebomb waiting to explode, and then... voila, it did, and i bet those random misfires were massive detonation. It sparked, but didnt ignite anything since it was already burned.
I mean for all you know you were running 16-20psi. No way to tell.
But hey man, i was just teasing you. I hope you learned your lesson though about how unsafe it is to turn the boost up without a gauge.

just logged on. In reply to kyracefans comment. He said strengthen welds on differencial. Are mazdaspeeds known for weak diffs, because mine is split in half rollin stock. The reason I ask is mazda wont fix it.

[KyRaceFan]

gcottons diff cracked.. mazda didnt cover it because of his fmic and exhaust
But yea im thinking the diff isnt the strongest, as there are only 2 welds holding it together.

Once i buy exhaust, and new tires, im gonna get it strengthened by the same shop working on gcottons diff now...

[BillyJoeldwain]

That bull crap. My car is stock and only half way into warranty. Any one know any one I can talk to

[KyRaceFan]

mazda N/A

basically its a waiting game
if the car is stock, they shouldnt have any reason the weld broke other than faulty workmanship.

Did you just say a T3 spools faster than a T28(boom08) (nuts)

[BillyJoeldwain]

my cars been sitting for 6 months. what the real deal is , my tranny was replaced one time because the diff stopped grabbing, andwhen mom picked up the car she signed a peice of paper sayingany more abuse by owner wont be covered. then the diff split in half 3months later

[KyRaceFan]

Did you just say a T3 spools faster than a T28(boom08) (nuts)
yea i saw that, but decided not to mention it.....
A t3/t04e 40 trim will be at 8psi by about 3400 on this car, and the gt 28 would be about 3000.

Both would make about the same power....

[AutoBox]

unless ut goin for 400whp a t3/t4 is worthless...if u want useable wide powerband...get a gt28 or just upgrade ur t25 with t28 internals.....no point in payin so much for a whole new turbo when ur stck on is nice already......(chair)

[Notorious]

I say gt28rs. great all around turbo, t3/t4 spools faster than most of you think. I had it on my civic and it hit full boost at about 4000 rpm. Besides do you really want all that power down all at one time, all your gonna do is smoke the tires.

Thats a great list, cept, if it's gonna be street not track, I'd say just keep the rims you have, but change tire compounds, and spend the rim money on some good gauges, and an FMIC(obviously with hardpipes and CAI). This is much safer for you car, instead of swapping out your turbo, and you will still get some power out of these mods, plus make it safe for future turbo modification.

yea good gauges are also important, and a good boost controller too, like an profec b spec II.

If he wants to autocross the beast, or go for it on the street, then input falken azeni sports in 225/45/17 on his stock wheels.

Also might add a p5 radiator.
the list goes on and on with what you can/should mod.
Probably need a walbro 255 fuel pump or some sort of in line pump.

Bolting on a big turbo isnt the answer for more power.
I was sorta trying to scare him into realizing this isnt easy.

Uh, please know what you're talking about before saying anything. A T3/04 turbo is HUGE compared to our stock turbo. It spools up extremely slower than the T25 and "at all stock setting" will not give the gains you mentioned. OrangeMSP (do a search for that member name) had a T3/04e setup before some of you guys were around on his MSP and I beat him in my MSP. The answer is not to switch out turbos and expect to be speed racer, it's about tuning the car properly. This T25 (as debated MANY MANY MANY times) will be efficient for most, if not all, of the people here when it's tuned properly which no one has done yet. Quit assuming our turbo sucks and instead of dropping 6k to make a "problem" quite a bit larger than it would have been ever before, use some sense instead of your bank account and get the car properly tuned in stock trim. Then and only then if the car is not powerful enough for you and you still have money left over for when your tranny blows apart, please upgrade turbos but again, TUNE it.

Also, please search about turbo upgrades. I've lost count on how many times this has been discussed and it's always been proven tuning is the key thing with this car, not a heavy wallet.

ANd one more thing, you said yourself that you're not that incredibly knowledgable about this car. I'd HIGHLY suggest you become quite a bit more knowledgable before you even THINK about doing a turbo swap. We're not talking about adding overlays or changing settings on a radio.
