How would you know if an old engine is still capable of handling the extra stress brought about by forced induction?  

hello po!
can a lancer pizza have a turbo even if it has an auto tranny?
tnx!

yes

Yes. I believe ERL Motorwerks has a turbo pizza.

 Yes pwede mo i turbo ang 4G15 or the 4G92 na both sohc found on Lancers ( PIZZA ) . Walang kinalaman ang tranny mo for hindering the installation of the turbo but as u know people prefer the stick shift / manual in modified vehicles specially cars .

 
I wouldnt know that but I will normally have a major tune up first and make sure no leaks and damaged gaskets then save enough money to cover the whole nine yards to bullet proof the internals to avoid future headaches then enjoy the turbo power !

yup it can be turboed.   my car is also lancer pizza A/T.  

sir gotboost,

any feedback? how was is it?

zero cfm,

ok naman kahit matic kaso invecs w/ sportmode yung tranny ko. hindi ko sure about sa A/T w/o sportmode kung may problem.

Do a compression test and know your stock engine's compression ratio.  Engines with over 10 to 1 compression ratio aren't the best candidates for a turbo.

A compression test is a good indication of your engine's integrity.  The cylinder with the highest compression shouldn't differ from the cylinder with the lowest compression by more than 15%.  If variation is more than 15%, I suggest that you first rebuild your engine before slapping on a turbo.

Only a cylinder leakage test will tell you where your engine is losing compression which can be at the intake or exhaust valves, head gasket or piston rings.

Though I know how to use one, I don't know who has a cylinder leakage tester here in the Philippines.

johnqpublic318,

Are you saying that if the result of the compression test is good meaning that the difference between the cylinders are not more than 15%, then slapping on a turbo is OK?

How about age and mileage of the engine? What's the oldest engine you know that was successfully turboed? Is there a certain guideline regarding this that can be considered rule of thumb?  

I had mine turbocharged without having a compression test done with a mileage of 75K on it.

So it does not necessarilly mean that a high mileage engine is not a good candidate for turbocharging.

Note: There was a car which was brand new, and was turbocharged using a T3-60 turbo, it did not last, but I don't know the whole story, my only point is, don't look at the mileage.

johnqpublic318 may be right, look at the engines health.

For instance, if you get 200psi with 1 cylinder then no other cylinder should have less than 170psi.  Many Engines will still run fine with up to 25% variation but since you want to install a turbo, I'd want a tighter engine.

But, this is not the only thing you need to look at.  A compression test is a good indication of an engine's internal condition but internal condition isn't the only thing that matters.

How good is your ignition system?  How much boost are you planning to run?  What's your stock compression ratio?  If planning to run high boost, does your engine have forged pistons?  There are many other factors...

i think honda shaw has a leakage tester but they won't do it in a boosted car and i don't know why.

I would suggest that you get a small turbo..the likes of T25, TD04-13G or TDO5H-14B. Those turbos spool up at lower rpm range thus providing stronger low end power to compensate for poor torque of an auto tranny.
