im looking to upgrade my Turbo on my MSP and i was thinking of putting a GT28, but what all do i need? including upgrades to other parts to be combatible with the new bigger turbo (fuel systems, computer, tuning, etc)and everything!! thanks......
 
Well if your going gt28......you would defintely have the supporting mods:

TurboBack Exhaust
Motor Mounts
Upgraded Intercooler (side mount or front mount)
Fuel Management System and a good tune.
Hard Pipes
Upgraded Bypass valve or a Blow Off Valve
WIDEBAND GUAGE
Boost Gauge
1 Step Colder Spark Plugs


Those are bare nessecities.

You can also add:
Cold Air Intake
Aftermarket Intake mani....(i.e. 626 single runner mani, 505zoom mani)
Shifter Bushings.....
Welded LSD better yet Quaife LSD
Better Tranny Gears
Forged Motor
Better axles
AfterMarket Cams
Ported n Polished Head
Lightweight Pullies

I am probably Missing a few things but people will either chime in and add on or tell you to use the SEARCH Button. I am in a good mood today so I gave you a list.
 
get Gt3071R with t3 flange - spools just a bit later then gt28 from my calculation.

its good for all the power you can aim for , you'll never need another turbo to get more power thats why i'm suggesting this one.

Gt3071R is a great move, but depends on what power goals your aiming for. And what you wanna do with your car. I mean personally in my opinion going over
320hp in a front wheel drive car is pointless.
 
plenty of 500HP fwd cars on the streets.. use throttle modulation or an electronic boost controller that has different boost levels for each gear to help with traction.
 
Why are you upgrading your turbo? the stock turbo is more than enough to pop your block.

You should just buy all the supporting mods you can before you upgrade the turbo. You will see such a huge difference that. What is the point of blowing more warmer air into the engine?
 
Just because there are 'plenty' of 500 hp fwd cars on the road doesn't mean it's a good idea to have one. Most of those would be what we'd consider to be rice (hollowed-out civic with flames coming out of the exhaust comes to mind) and almost all of them would be on cars FAR better designed to handle this type of power (aformentioned, DSM twins, etc.)

So if you want to blow your engine (forged internals was mentioned as an afterthought) not to mention your wallet... go for it. You'll have a car that, once (if) it gains traction will be able to go REALLY fast... in a straight line. but go through the twisties and you'll be laying off the gas about as much as the blue haired lady that rings out out at wal mart. with all that torque steer (not to mention understeer) the car will be a sloppy mess in almost all conditions. Did I mention all this is gonna cost you a shitload of money? lol If you want a car with that much power... be smart and sell the MSP and get yourself a... I don't know... WRX or Mustang or Camaro or.... s***, there's probably 50 cars that are better choices for this. but good luck. we're all pullin for you.

If your turbo is fine def. go with what kamon said, but i was able to get some else to pay for mine cause i said it was going bad lol, so i went with the GT28RS cause if your not paying for it mine as well get the bigger one.
Also would you need a dif. mani if you went with the GT30, i thought the GT28RS was the biggest we could go with it being in the stock loaction??
 
^ Word. the stock turbo is a mean little fugger. with all supporting mods you can definitely get the car going. I sometimes miss the instant spool. :(

This is what i did when i got my GT28RS, this is the stuff i got when i placed my order.

I would really recomond getting atleast these.

Walbro fuel pump - highly recomend
Corksport DP since you will the turbo off.
I also got the Splitsecon AFC
AEM wideband
Motormount
New Studs for the stock mani
lots and lots of PB blaster

of course theres more but thats the what i had done to it and it was fine, i already had exhaust and a FMIC

But if your tubo is fine i would not worry about cause i lost power when i went with the GT28RS and all the s*** i added, my car is safer but not as fast. No internals means lower boost you can run, i was running 11 on the stocker and only 8 on the GT28.

the GT28 is not that badm, maybe a grand at the most later, atleast thats what i noticed.
 
the turbo speed 3.5 was talking about wont fit in the stock location it has a t3 flange vs the t2 flange that comes on the msp manifold. Now yes a couple months ago you would be correct that the 28rs is the biggest we could fit in the stock location, but now we have another option that will fit in the stock location. We can now fit a gt3071 in the stock location. Jdm sam has the turbo with the t2 flange and t2 5 bolt discharge housing. Also it has a custom smaller compressor housing so it can fit in the stock location. So yes now we have a bigger option

if you think MSP's sucks and WRX, Mustang's or Camaro's are better, why do you own an MSP then ? have you been in a High Powered Protg before ? , I've seen a few, CWILL, JOMO etc and been on SuperProtege , all i can tell you is that you really have no idea what these cars feels like, and what they can really do, based on my personal experience i love how the Msp's handles and any modded Protg feels in every aspect, how they look. i have no traction issues and much less is a mess in any condition. when you seek for high HP numbers you have to take care of lot's of details to take that power to the ground. Good Motor Mounts, Good Suspension, Wheels and Tires, Drive Axles, Better brake Pads and Rotors, good and better Brake Lines etc. there are lot's of Fast Daily driven FWD cars with big Horsepower that are kicking mayor butt to those cars you have mentioned above, i don't see a Mustang or a Camaro better than a Modded MSP Protege or Protege5, and much less a WRX. i respect your opinion but i don't share or agree with it. if you are looking for a fast daily driving car you need to spend s*** load of money anyways don't matter what car you choose to start with. and you really don't need to spend that much money to have a fun fast MSP, you could make your MSP a true Street killer, with Coilover Suspension, or Lowered Springs, some Stainless Steel Brake Lines, Cross Drilled and Slotted rotors and some nice brake pads, a nice 3" exhaust, a good intake system, a FMIC or a Methanol injection kit on your Stock SMIC, better spark plugs, better clutch like an ACT Heavy Duty Pressure plate and Performance Street Disk, it all depends what you are looking for to have, I'm pretty sure everything i have mentioned above can be done by your self to save money, except for the clutch which is a pain in the butt to do... it all depends of what you want to spend and what you are looking to have. you don't really need a 500HP car to have fun, and much less you need a WRX, a mustang or a Camaro to have fun.

sorry to break it to you miguel but the sti,mustang,and camaro are better enginered cars. Do i think they are better then my car ? depends on how you look at it. are they faster from a stock stand point yes. do they handle better from a stock stand point? no. Ill tell you now miguel you can go thru twisties like a normal modded msp would. a normal modded msp with a fast spooling gt25r would eat you up. One more thing you cant tell me you have traction in the top of 1st gear or second gear for that matter. Also yes there are alot of 500+ fwd hondas and ask them is that power is streetable. They will straight up tell you its not. Its too much power to put thru the front wheels and still try to keep traction. Thats why you will ALWAYS see more higher horsepower cars in RWD and AWD platforms. Actually no you dont need to spend alot of money to have a fast daily driver either. How much did that 400hp sti have in it that you raced the one night you had your car before you went back to spain 6k? that is not alot of money compaired to what you or my self have spent. Also ill say msp's SUCK for trying to go fast in a straight line UNLESS you spend alot of money on them.
 
whoa... easy killer. not sure you got the drift of what I was saying so I'll rephrase.

I only recommended those other cars because they are (without question) better platforms for someone who's looking to get the most (useable) hp for the least dough. While it's an irrelevant point, for the record... my lack of interest in owning any of them falls in line with my (relative) lack of interest for "going really fast in a straight line." (which is what, wrx aside) those cars are best at. Personally, I'll choose a car that handles well over one that goes really fast any day. But again... that's beside the point.

Getting back on track.. you, whether you realize it or not, made my point better than I could ever have. All the mods you listed... all the things you admit are needed in order to make a high-hp fwd car "work"... to me, that just reads 'time and money'. Maybe some people don't value their time (or money) as much as I... but the 3 most important letters the alphabet to me are ROI.

But whatever... we all have our oppinions and hell.. . who am I to tell someone else what to do with their money?

Thank you Ryan. Thats pretty much what I was getting at when I posted above. That couldn't have been better put. But I guess to each their own.

Well first he said WRX, not an STI, well about the twesties do you drive in twisty roads everyday ? are you in a track everyday i doubt it, a very fast spooling turbo is not a good idea to have, it all depends on your driving habits, I' am tired of seeing crazy and monster Honda's with 400whp all day long, my neighbor have a 2000 civic hatch with 490whp, and he drives his car everyday, go to work etc, because basically he don't have another car, i mean you can always lower your boost and use low boost for daily driving, he have everything done to his suspension and the car handles just like it were on rails. everything depends .. about RWD and AWD cars, they also have traction issues when they get to a certain amount of power. about the Sti i raced yes he had 6k on his car, but the main difference is that his car come from factory with 300 HP and cost around 36k new. yes i have spend lots of money on my car but my car were cheaper brand new i paid 19k for it. and i added the amount of money you already know. so at these point if you calculate the amount of Money he paid for his STI new, and the 6k he putted on it, we are almost even in the same about of money invested in our cars and i still were faster than him. so it all matter what you can afford, if you can afford to buy a 36k car and add another 6k to it for a total of 42k or you can buy a 19k car and build it from scratch to make it better and fast, i feel more proud to own a Mazdaspeed Protg with 25k on it, than get a more expensive and supposedly better and faster car and still be faster.. you get my point Ryan ? i know that is hard to spend that amount of money i did on my car but also is hard to buy a 36k car and then add another 6k to it... at the end we both have spended the same or close amount of money in our cars but like i said i was still faster than him coming from a weaker and cheaper platform car...

I mean it all depends of what you want, and can afford and the most important thing is what makes you happy... but i still think the Protgs in General are great looking Cars, they handle very good and they just look like no other. there are lot's of nice, very nice Protgs in these Forum that are not fast but they look just like no other, there is no need to have a 500 hp Car like you said, but if you like it and can afford it why not, why not make your own car better and faster. just my .02
