Turbo

[CodyScott]

What would be the best turbo for its price for a 2003 protege5 and what has to be done to the car first before you can turbo it...im like for like +15-18 boost

 

[ap123]

If you're looking to run that much boost:
Built forged engine
A good EMS like haltech, along with other goodies like fuel injectors, sensors, fuel pump....

 

[CodyScott]

How much boost can I run on an l4?

 

[azuelke]

The stock engine can handle 8 psi pretty well, anything more is pushing it, and your range will require forged parts.

You can run 12 to 14 fine with a really good tune. Still though u are more likely to snap a rod with the extra boost. Build the motor and u will have a good time

 

[CodyScott]

What should I build on? Forged pistons ect....

 

[kms1990]

what can a stock p5 motor handle without extra mods? i am skulking out a turbo and would like to know

 

[CodyScott]

From the looks of it people are saying 8 psi but I'm curious as to what engine internals I need to replace to be able to run a higher boost withiught breaking anything.... If anyone can help please do....

You have A LOT of learning to do sir. First off, try searching. There are endless amounts of topics about turbos and our cars. It would also help to learn about turbocharging in general. Just saying "I want to run 15-18psi" is very vague. Depending on the turbo that can produce many different power levels.

You need a clear cut power goal, and a crystal clear budget. If you are lucky, You can get a stock MSP setup for $1000-1500 providing you do all of the work. That's 7-8psi on a t25 turbo, topping out at ~180hp depending on bolt ons. If you want more power you are looking at lots of aftermarket parts, at least a piggyback ecu. Custom work, you name it. I would hazard a guess that if you wanted to run 15-18psi reliably and daily and provide good power numbers on a stock MSP turbo you'd be looking at minimum $3-4k if you are lucky. And by no means is that even remotely ideal.

I'm not trying to tell you not to do it, but you've got to know 100% what you are getting into beforehand.

Good luck.

Thank you a sound answer hahaha

Don't bother trying to boost anything on the stock protege

 

[CodyScott]

Are you saying to drop a new engine?

I'm saying take your time and think what you really want..if u want to put basic boltons and run a super safe 6-7psi of boost daily then kool.....if that's what you REALLY want. Now if u want to grow with your car then that's a totally different ball game,you might just save your $$ and get it properly done ONE time...do lots n lots of reading if you haven't yet. You need to understand the game...

He's right....

I know and I haven't done much reading I'm trying to fi d a good place to start

A good place to start would be a reputable tuner shop that's close to you. Go and speak to the head mechanic and tell him your plans, he should be able to tell you ( or possibly show you) what's involved and probably point you in the right direction, but that does not mean you don't have to read up on you own....good luck this game is highly addictive hehehehe

The GT25 is done at 15-16psi... I mean, it's absolutely worked to the max. I am forged running 15ish psi.

I blew 3 engines at 10-12psi, one boost spiked to about 16psi and grenade. Other than that one, the others were caused by oiling issues. The FS oiling system is garbage.

I have all the mods listed in my signature, and had I not gotten deals on the everything or been able to do all the work myself, the money I would've spent would be insane. I mean, it's insane as it is considering I'm praying to be at 300whp when I dyno. Or at least close. The Protg is just a "different" platform. It's not necessarily bad, just not as much support and options for us..
