200whp+ safely

[PlatinumMSP]

what would be the cost of labor and the time needed to swap pistons and rods?

 

[MyOrangeToy]

So you guys are saying a MSP will make 200 whp with turboback, boostcontroller, intake and some kind of ECU?

 

[PlatinumMSP]

Dude, if you only want 200 whp, you don't need a full exhaust. Get an Apex 2.5 incher. I got mine for $125 used about 1.5 years ago and it's still holding strong. You can keep the stock resonator and muffler too, keeps the sound quiet and stealthy. Or just go to a muffler shop and get a straight pipe made. Guys here in Dallas are doing it for $60 and seeing good gains. Just getting rid of the cats is all you need to do to the exhaust on a 200 whp car.

Get a new front motor mount and a rear one if you can afford it. The stock ones will definately rip. Those run about $80 each.

Upgrade your intake with a used injen - $125

Get a manual boost controller at 8-10 psi - $50
----
That's only about $450 there. Enough left over for an upgraded SMIC or a DSM AFC and you'd be over 200whp for under $1K.

i'd like to do it without blowing my engine and staying within emissions, yeah i know motor mounts are in my future, i'd like to stay away from the mbc though i think that has led to the death of many engines here on the forum, which apex 2.5 incher are you refering too? the catless dp? i think i can get a catted MAM midpipe for like $200 but from what i hear, i need to free up the whole exhaust to keep my engine alive before i up the boost any

its been done many times man, i'm just looking for the right route there, i'm considering saving up for a vibrant exaust, i want at least 2.5", the corksport just seems a little too cheap for some reason...

 

[MyOrangeToy]

wow... seems like i m not far from 200whp!

I have Injen CAI, Apex 2.5 DP(1 cat), custom cat back, FMIC and a HKS EVC

You don't need to free up the whole exhaust to get 200 whp. A 3" one is severe overkill for that power level. 2.5" will be plenty big enough for 250whp. A 3" exhaust on a 200whp car will just make your slow car sound loud and annoying.

The Apex exhaust I have is the 2.5" catless one. If you just replace the mid pipe then it's only 4 bolts to swap on the stock pipe for emmesions testing, and that's only if you are in a state that makes visual checks. If your state only reads the ODII port, you should pass as long as you don't have a CEL.

MBCs haven't led to the death of any cars, poor driving habits have. Boost smartly and you'll be fine. Stay out of boost in 5th gear (4th gets you over 100mph), Use high octane gas, and roll into the throttle to avoid large boost spikes and you'll be fine. Most blown engines have happened from excessive boost in low rpms due to driver error.

At 10psi you should be very close. With some EMS I'm sure you'd go over that. Time to hit the dyno and find out for sure. (thumb)

 

[mspeed101]

all you need is intake, fmic, 2.5inch downpipe, boost controoler @ 10psi, and afc to hit 200+whp

 

[DiscreetSpeed]

So this is my plan to get over 200whp with just two more mods to my current setup....

3" full exaust
Unichip at hi-boost

thats about all i want to do to my car, opinions? i'm an engineering student so i dont have time for a job, but i cant help but want to mod my msp, my funds pretty much come straight out of my student loans, so i want my mods to count and not blow my engine

what do you guys think?

good luck (thumb) sounds good

 

[Cusson]

To give you an idea, I'v done 193whp &198 ft/tq with FMIC Ion, CAI AEM, 9,5psi and the stock exhaust of my P5. So with a full exhaust and a AFC, you should do your 200whp.

Boosting in 5th

How exactly do you avoid boosting in 5th gear? newbie question but I haven't found the answer after doing a search. what would you need to do to have boost only running through the 1st 4 gears?

You don't need to free up the whole exhaust to get 200 whp. A 3" one is severe overkill for that power level. 2.5" will be plenty big enough for 250whp. A 3" exhaust on a 200whp car will just make your slow car sound loud and annoying.

After you give the car a certain amount of throttle you will leave vacuum and enter into boost. Basically when in 5th gear just keep a steady amount of gas while cruising and you easily stay out of boost. To be able to monitor it better you need a boost gauge so you know when you cross that line.

your throttle position creates pressure changes in the engine and that's where your vacuum and boost come in. at various throttle positions (how far you press the pedal down), you will generate a certain amount of vacuum or boost. alternately, you don't have to boost at all in any gear if you don't want to. when i'm cruising slowly in the morning to work, i usually don't go into boost at all. you can give it partial throttle and take your rpms in first gear all the way to redline if you want without going into boost.

Boosting in 5th

Ok great thanks guys, VERY clear answers...I really appreciate it (thumb)

 

[TX Speed Demon]

Yeah I just meant I don't push it in fifth gear. Fourth gear will take you over 100mph before readlining. Never had a need to push it any harder.

Install a boost gauge and you'll know for sure.

 

[Lil Freek]

meh.. i'll get to 200whp on 10psi.
figuring 10psi + 2.5" w/ hiflow cat + FMIC should do it nicely...

although i'm not going up to 10psi until my MPI is PROPERLY tuned - to ensure no-boom

 

[mazdaspeed75]

Ok forget 200 whp , Turn it to about 12 psi with mpi ,lots of timming pulled and 12 .2 a/f and get 230 whp maybe more. Its fun and i will see how long it last . (boom07) Of course with proper mods .

 

[Lil Freek]

hahahaha... i'm going to buy a second engine this summer... but that'll stay stored until i need it..
it'll either be a backup or a built engine... more likely a backup since i wanna see how i can buy an evo8

 

[rocketr2]

So you can never boost on 5th gear ? or KABOOM ! ???

 

[mazdaspeed75]

,

yea you can its just stressful espically at high boost . It puts stress on the rods.
