Ideas on reaching 250hp-reliably

[jeffmsp]

hey everyone,

being new to the msp, i was wondering if i could get your opinions on how to reach the 250 hp mark reliably. It doesnt have to be the cheapest route (cheap doesnt tend to mix with reliable), but i would like your ideas/opinions. I have no experience with the FS motor (i prefer the b series personnally, not sure why they didnt use the 1.8bp in the mazdaspeed like they did in the miatamazdaspeed) But anyways, thanks for your time.

reliably? You're talking upgraded turbo- perhaps a gt28rs ('disco potato') pehaps with custom trim if you wanted to REALLY push it. Standalone, custom tuned computer mapping ($$$$$$$$), injectors, axels, maybe *some* tranny work, etc.

$6500 for that with reliability. not to mention everything else you'd want to upgrade if you had 250hp.

if all that were done wouldnt it allow u to go past the 250 mark?

 

[mazdaspeedpower]

ask discreetspeed, he knows all about the 250hp mark, as do several other people, he's just the only one I can think of right now.

Yes but by detuning it a bit to 250 it would be much more reliable than if you were pushing the limits at 250.

I'd think you would want to strengthen the engine internals first. They your typical bolt-ons, i.e. CAI, FMIC, MBC, FCD, DP, CAT-BACK, and set boost to like 12-15. You'd easily be up there, and it would be reliable... I think. Then again, I may read to many magazines! lol

First off, there's a lot of mis-information already. 250bhp doesn't take many mods, but it does take the proper ones.

SRI, FMIC, Turbo-back exhaust, Boost Control & EMS- BAM 250hp.

Reliability will be decided by which EMS you use. Checkout the tuning forum for options: MPI Tuner Piggyback, AEM PnP, Microtech, Haltech etc. We all have our preferences.

 

[changedman]

yes, you'd want forged internals. i figured the price of them in. you'd also need high octane gas.

mx3- he said he didnt want to take the "CHEAP" way

You can reach 250hp with the stock turbo.

Forged internals of course.

Go with the standard bolt ons: SRI, FMIC, full 2.5" or 3" turboback.
Get the AEM PnP EMS.
IC sprayer or water/alcohol injection.
ACT street clutch.
Tranny should be fine if you don't abuse it.
Up the boost until you reach 250whp...shouldn't really be that high (probably under 15psi)

Should easily make > 250whp. Plus with the AEM, and the water/alk injection, should be very reliable.

 

[low_psi]

yes, but forged internals and non-pump gas is ridiculous for a goal of a reliable 250bhp.

it can easily be achieved with basic boltons and proper tuning. if you want more than 240-250whp, that's when I'd consider internals.

oh, don't forget you'll need a clutch

Water/Alc injection is not needed for 250bhp or whp... The internals will NOT give out at 250bhp..

 

[jersey_emt]

He said he wanted reliability.

The stock internals *should* hold 250WHP with proper tuning, but to be on the safe side, I would want to be forged before I reach that level.

And water or alch injection cools things down significantly, increasing both power AND reliability.

jersey_emt lays the smack down!

I agree that 250whp calls for new internals rather quickly, but he's stated 250hp, so until he can clear up where he wants all those ponies I think its best to not potentially exaggerate the extensive-ness of the required modifications.

Water/Alc would be great, but its just not needed at only 250b/whp. Money would be better spent on a new radiator and fans IMO. 250b/whp is not some HUGE deal. Next people are going to reccomend dropping compression to 7.5:1

people are confused and misinformed here, most of them are driving around in stock cars while trying to give advice... 250bhp does NOT require internals. ES's msp dynoed at 250fwhp and almost 300tq with your simple bolts ons, fuel regulator and standalone. it can and has been done people, its all in the tuning. good luck

weeeeeeeeerd.

 

[BinaryRotary]

Heres what you need :

Hardpipes - $300
CAI - $150
FMIC or SMIC - $1000
Engine Management (Unichip, MPI, AEM) - $800
ACT, Exedy Clutch - $350
Electronic boost controller - $300
2.5" or 3.0" turbo back exhaust (Ion, Apex R1, Custom) - $1000
Pivot Water Injection control - $150

Grand total : $3150

In the performance world, theres no such thing as cheap and reliable.

I would also suggest adding to that list that most people has colder plugs, upgraded radiator, gauges for knowing what is going on in your engine, and better brake pads and tires, cuz you'll need them to handle those new power of yours

 

[BlueMP5Dave]

Standalone / piggyback, boost controller, Intake, Exhaust, Intercooler with hardpipes, Higher flow fuel pump, Wide-band O2 to ensure proper mix, Egt guage to watch temps, Lots of tuning.

Do forget Clutch when it dies you must upgrade!

Although I don't have my turbo project done, this is the route I am taking once the Turbo is installed. I have the research complete it is just putting it to use.

I think you have set a resonable goal. Do it right and take your time.
