P5 Turbo Incoming

[HateSmokes]

I have a 2002 P5. I want to turbo it eventually, but I want to get the engine and fuel/spark systems ready to handle the boost first. Suggestions on where to start would be helpful. As far as I know, no mods apart from CAI and cat-back have been performed. Should I start with the spark? Engine internals?

Internals for sure. Price per horsepower on ignition systems are just stupid. You'll be spending so much money on AEM Smart coils and Twin Spark ignition modules and only see a few hp maybe. Get your engine and trans ready to receive boost first. I mean you could run a stock MSP turbo setup and be fine with 170hp... although stock MSP's have thrown rods before soo...I'd start with internals.

Hey thanks Brian_K.

@Twi7ch: Yeah, I don't want to buy anything that doesn't fit into the end goal if I can avoid it. So like a set of forged pistons and rings? Maybe rods, bearings, and a forged crank shaft? Or maybe valves, springs, etc.?

I know a few buddies that have experience building/maintaining race cars, just no street Mazdas of any kind. So while I'll have plenty of help with the hard work if/when I need it, no one felt comfortable giving advice on where to start with my particular motor. A couple people just reminded me to check forums so here I am. Thx guys.

Read the link Brian provided.

All protege engines and most other Mazda cranks are forged.

The connecting rod is the weak part, but you might as well get forged pistons too.

As a clarification, only 99 and up Mazda FS cranks are forged.

I would love to turbo my protege5. How safe would it be to just throw on a MSP turbo setup on a stock P5 engine/transmission?

 

[MrGiggles]

The MSP engine and Protege5 engine are identical.. The stock MSP only runs around 6 psi of boost, it would be perfectly safe as long as you don't run more boost than that. Aside from just the mechanical parts, you'll need to run a MSP ECU and the other required parts so you don't melt a piston. Can't just slap on a turbo and run with it, it goes deeper than that.

I believe the transmissions are the same as well, but the MSP has a factory LSD.

 

[AxelSheppard]

Any idea how much it could cost for all that if you did it yourself.

 

[MrGiggles]

If you're patient, a used turbo setup from a MSP can be found for around 1000 bucks.

 

[AxelSheppard]

That would be a dream. Maybe someday!

I know I am kinda necroing this thread, but I just wanted to say thanks to anyone who has or will post with helpful advice. I appreciate it.

Excellent info, that saves me some cash. I very much appreciate it!

@MrGiggles Also appreciate the clarification.
