how much boost can a 2.0l oz lancer 03 take i was thinking 4-5 lbs max stock was also wanting to know what turbo kits would be the best to use:

 

T-25 on 6 lbs of boost non intercooled is probably the best bang for the buck. Road Race Motorsports sells all kinds of kits. Please Search as advised by others.

 

First volley of "search, noob!" responses deleted. I don't expect anymore... hint, hint.

It depends on the turbo, of course. On the kit that RRM sells, they recommend you start out at 7 or so. The number I generally associate with piston failure is 10 (from what I've read) and the rods are more like 14.

Welcome to the site. Please explore the different forums and try the search feature, as it will help you out.

EDIT - this will go in the turbo forum tomorrow. Just want to give the OP a chance to see it here, where he left it.

 

general psi for most kits is right about 7 psi. rrm kits are the cleanest nicest kits but they are a bit pricey. You can allways go custom. I plan to use a stock evo 16g6 turbo.

 

^Stock about 7 psi intercooled "safely"... Like mentioned already, that would be dependent on the turbos "size". RRM, A2, etc

 

depending on how custom you go (aka larger injectors), you could probably run higher, just make sure that the tune supports your higher boost... don't want to send too much air and too little fuel or vise versa into the engine

 

i'd like to add to his inquiry. how long you think the stock clutch will hold up on a basic turbo upgrade. say t-25 non intercooled.

 

I honestly think people need to get away from the non-intercooled turbo plans. Do you realize that the compression of the turbo'd air is heating the air up tremendously. This hot air is going straight into your engine and raising its temperature to the borderline of the heat causing the fuel to explode spontaneously (detnation). Mix in the unlucky situation of a super bad detnation and kiss your motor good-bye. Just intercool that flow to cool it down and your engine will love you for it. Plus, you then have the basics for an upgradable system to push more boost. Sure, it may be the "cost effective" way to say you have a turbo, but it's risky business. Consider that before you risk it is all I'm saying..

 

i know.... your right. especially since a t-25 spins so fast to make its boost[say250,000rpm] it really heats up the air. its just such a big jump $ goin intercooled of the bat. still how long will the stock clutch hold up with boost.

sorry to hijack. just figure one reading this may wonder the same.

 

It all depends on how you drive. If you dump the clutch constantly, not very long.

 

I had about 50,000 miles on my clutch when I got my supercharger. After about 1000 miles of FI (at about 180whp) my clutch started slipping. And I almost never dumped the clutch.

 

well i had to replace my clutch at around 52000 on the car, and the guy who did the clutch replacement for me said that the previous owner had already replaced the clutch... so if you plan on turbo, i'd plan on replacing the clutch soon after with a higher performance clutch because the stock one is just not going to do it for real long

 

I 2nd that, all that heat from the turbo raising on the engine will not only cause detonation, but every component and material is set to operate at a certain temperature. The metal in engines contract and expand with differences in heat, so to compensate for that, the engineers had to go with wmaterials that would be best at a certain temperatures. Normal operating temperature is the longest life for all of your engine, above that will cause significant loss of engine life.

 

Depends on how you do it. We have customers boosting from 5 to 18 psi. Need more answers before we can answer your questions.

so i gather,
one could get away with a stock clutch on boost considering they take it easy, but dont count on it.
non intercooled boost {may] cause detonation,and expanding of internals due to heat from the charged in coming air.

what if one used a different turbo. one that didnt spin at such a high rpm heating the incoming air so much.
really all in all an intercooler is neccesary. considering the cost. ah nevermind.
another thread another time for this. sorry so far off topic.
