Sup guys, I know i've read about this in threads before but i couldn't find any threads in the search for the few minutes that i looked. I was just wondering how much work is needed for a mazdaspeed turbo kit to work on a p5. Is it safe? How much power would it make if it worked? Can the engine management handle it?
Thanks!

you would basically need an entire wrecked MSP to make the swap work and even then it'll only ne as good as a stock MSP.... I suggest just buying an aftermarket turbo kit or waiting anothe rmonth or so and buying my supercharger kit.

.... and front clips of Mazdaspeed Proteges are not that easy to come by. Trust me, I know - I've looked!

There are several turbo kits on the market for the FS 2.0L. Wagner makes one that betters the Mazdaspeed output, as does Hi-Boost in the Toronto area. Both are designed to be easy bolt-ins, running with the stock compression ratio.

Keep an eye on the supercharger development going on in this forum as well... a lot of thought and hard work seems to be going into it. There has been a lot written on it, so check it out...

I know a lot about Rod's SC and all the other turbo kits, and i've had my eyes on the hiboost for a long time, but let's say i COULD get my hands on a MSP turbo kit. I would be down to get it because it would give me a nice boost over stock and it wouldnt cost $4000. Does the MSP have basicallly the same ECU as the p5? What are some other components that should be included in the kit aside from the turbo?

I'm in the process of doing this on my ES. It's a much cheaper solution and you can buy Mazdaspeed upgrades down the road to get the same output as a bolt-on kit. As far as fuel management goes all you'll need is the MSP ECU. There's also an issue with the oil supply and return lines - you'll have to tap the oil pan unless you can get ahold of the 'main bearing support plate' that comes on MSPs (under the engine block I believe) and has the oil lines built in. If you get the MSP side-mount intercooler you'll also need its radiator (or AWR's high-performance) since the P5's is too wide. Here's the parts list for what I'm putting in (you wouldn't need all for a stock MSP setup)-

-Manifold/turbo (Garrett T25)
-SMIC/hardpipes (stock MSP has plastic pipes)
-Radiator
-ECU
-HKS BOV
-Airbox/intake pipe
-Gauges (your choice)
-Clutchmasters stage I clutch
-JoeP FCD/FCP/MBC
-Custom exhaust

What's your total cost, Doodsmack? How much cheaper is a DIY vs. a kit?

from what i know, the msp has and 3rd gen RX-7 bov, one of the best sounding bovs IMO

For me it'll be about $3000 (and includes much more than a bolt-on kit). If you buy all stock MSP parts used from different people you can probably keep it under $2000.

I will be curious to know how it comes together. Keep us posted on your project, ok?

The trouble with a lot of DIY turbos is a lack of durability or driveability problems. But, since you are using Mazdaspeed components (and are changing to the turbo ECU for appropriate spark and fuel maps), it sounds like you've got a good plan - take what Mazda did for the Mazdaspeed car and improve on it.

That's pretty cool.

let's clarify something....as far as turbo systems go..the MSP system is crap...ANY aftermarket system out there will produce more power and do it reliably in comparison to the MSP system...the only good thing about the system is the T-25 which matches the engine pretty well...the manifold is cast(strong but horrible flow),the intercooler is just borrowed off the turbo diesel protege in europe, and is way too small...the tuning is crap..a bit of fuel and spark mods...downpipe is too small and restrictive...i see way too many guys blowing engines....most "stock" turbo systems are built much better, and include stronger internals,lower compression, better fuel compensation,and stronger drivetrains.....wanna do it right..talk to Matty about his supercharger, or go with a wagner turbo system, much more planning wen into both

Doodsmack

It seems the thread starter's main concern was cost, the main advantage of a DIY. Obviously a stock MSP setup will make less power than the other solutions, but with another ~$1500 you can make 200+ whp. Few aftermarket turbo systems include fuel management and other essentials, which requires more spending on top of the kit and labor. The supercharger will provide good bang for the buck, but many of us use air conditioning regularly.

macdaddyslomo

do you seriously think you can aquire ALL the stock MSP turbo kit peices used?? Mazda WILL NOT sell them... some peices you could possibly buy from a MSP owner that has upgraded,but most you cannot,and good luck getting them cheap. The manifold being the biggest obstacle... If you really want a cheap way to make a turbo kit...get a log style turbo manifold made,then buy a used T-25 off of Ebay, get a custom down pipe made, and buy some steel tubing off JC whitney for either straight charge piping(non intercooled,good for 5-6 psi) or more piping and a starion FMIC from a junkyard...use a BEGI RRFPR and you could probably peice a decent kit for $1100-$1200 and it will still make more power than a MSP.

Already have em.

This is a very interesting post, because I am thinking of upgrading my MSP; therefore, I'm getting rid of my turbo system. I was curious if I would be able to sell it to other protege drivers...........

DIY kits can be great or they can be crap.

i would think finding a tubular header would be more difficult than anything else. there are some good log headers out there, like whats on my SVO. it would be cheaper than tubular.

why use a T25? step up to a T3 with a .48 hot side. hell, the MSP doesn't get solid boost until close to 4000 rpm.

use an intercooler from a supercoupe thunderbird. they move alot of air, plentiful and cheap.

exhuast for the setup would be easy. a couple flanges, about 4 feet of 3" tubing, single aluminized 3" 90* and another 90* to section up for any other bends....
