Mod ideas, Best bang for Buck

[kbull38]

Thanks for the replies for my mod ideas, best bang for the buck thread. I am not new to moding cars, but this is my first experience with moding an import car so I am a litte slow on the technical lingo that I recieved from the thread. I have mechanical knowhow (my best time on changing the cylinder heads on my 1971 buick skylark was 90 minutes from draining the radiator to starting the engine after the change, heads ported and polished by my friend), but this is my first turbo car and it will take me some time to get up to speed (I am going buying mags to help me). I would like any pointers on making these changes as easy as possible and some estimates on HP gains I hope to expect, I want to get my new ms3 to run low 14's in the quarter. Thanks!

Doesn't the MS3 stock run mid to low 1/4 miles already? Below is from motortrend:

"At the track, the new Speed3's performance was not all that different from what it was the last time we tested it (that one was a 2009 model). This year, the hatch reached 60 mph in 5.6 seconds, which is exactly as quick as last year's model. It completed the quarter mile in 14.1 seconds at 99.9 mph (as opposed to last year's 14.1 at 100.6 mph), and braking in both cases was 112 feet."

It should, but at altitude you often see low 15's.

Ive got a tremendously helpful book for you...its called Ultimate Boost by Corky Bell. It goes in depth on building/tuning/testing/installing turbocharger systems. Gives some engineering background of turbochargers. It also will direct you in the proper direction of how to get the most power out of your turbocharger without doing anything to hurt your car.

In a sense, you'll achieve the most HP from reading that book.

But with a slew of bolt-on mods (ColdAirIntake/Turboback exhaust/Downpipe/engine mount/blowoff valve)

you could see anywhere from 20-40+whp gains...once you tune...and that's a modest number.

upgrading your turbo will yield the greatest HP gains of anything.

Turbochargers are easy (its a compressor and turbine that's forcing a charge of air into your cylinder producing a certain amount of PSI..I wont insult your intelligence by explaining them in detail...since I know you can read lol). engineering them is hard, haha. Rule of thumb is...the freer the airflow through your engine...the more power potential your turbocharger has.

If you want numbers...check out some of the Mazdaspeed owners on Cardomain who have dyno sheets up proving numbers for their mods.

Downpipe and you have no traction...

Why is That? ha stupid question...

Ho ho ho, the awd guy made a funny. I don't need traction from a 40 roll.

On topic though, my plans are intake, turbo inlet, downpipe, cobb AP and a tune, plus other miscellaneous things like a BPV, short shifter, rear motor mount. Not sure if I'll do the upgraded TMIC or not. The AP and tune are already going to be pretty expensive.

Those are bad launch runs though, right? My SRT-4 ran a 14.7 bone stock at PMI and I suck at launching FWD cars. I think that was with a 2.4 60'. My best run modded was 14.3 with a 2.39 60'. I'm sure a decent driver would have had it in the 13s. I know the MS3's strong point isn't the 1/4, but still, 15s is RSX territory and that makes me sad. :\
