so i read all about how reliable a turbocharged honda/acura can be given the fact that it is built/tuned/ect properly.

but how do yall really think they are compared to say a turbo neon, evo, sti (any car that comes from the factory turbocharged)? (reliability-wise)

Tuned and installed properly, very very good, but not as good as factory turbo cars because they usually come with better built motors for boost.

ok, well, lets say we build a block....sleeves, pistons, rods...

for example...sti has 300 hp
say we get a built acura/honda at 300 hp as well...

would the factory turboed sti still be more reliable?

 

if u took a honda 1.6-2.2 liter motor and stuck a dinky lil T25 or 16G turbo on it, and limit boost, i'm sure it too will be reliable and last for awhile but also wont make much power.

even on factory turbo cars i've seen them blow up and when they try and make more power by upgrading turbos etc......they too become unreliable.

Take a stock lower compression honda motor, put a small turbo on it and boost moderately. and leave the boost hella low and i'm sure it'll last forever just any other factory turbo car.

but in all reality, it is not in "OUR" nature to put a turbo kit on for small boost and minimal power outputs. we strive to go faster and make more n more power, which is why we sometimes have to blow things up

That is true.

 

no, it will never be as reliable, because whenever you add more parts to something, you add more potential for malfunction.

 

I think this guy said it best:

good read and he has alot of good points. 18-24psi on a stock motor is crazy. kinda hard to believe.

but he also left out a few other very important variables like timing, compression, egt's, cylinder pressure etc....... also alot of dohc honda's are meant to be NA and therefore their compressions are pretty high for stock motors (10:1+).

but all in all good read. And i like the fact that he makes it a point that people shouldn't blame Drag for selling a shitty turbo kit when people run it pass its suggested boost levels.

 

so according to that article, it seems as if you limit yourslef to say...7 psi....and keep it like that, you should be as reliable as a car that comes turbo from the factory...

 

The instant you put 2PSI on your engine you will decrease it's life. The more power you push above stock the less reliable it is. These engines have been built for a specific Horsepower, powerband, and transmission even. Every single aspect was looked over and calulated to fit that specific engine output.

No car will be a reliable as stock once boosted. Realize let's say your oil line pops off or your return line pops off or anything else. Also the added stress will wear EVERYTHING out faster. It is very possible to have a boosted hondas run for a long long time say 75k miles, but it would have done 200,000 if it was stock so.....

Furthermore I actually didn't like that article because all he says is if you can run more fuel you can run more boost.... . Other factors like timing and especially stressing out key compnents like piston ringlands (weakest part IMO). At some point engines need to get built to take the added abuse, Even built engines don't last forever.

 

He did leave out a lot, but I think the main point he made was that people who boost their Hondas tend to turn up their boost until they blow their stuff up. I did it on my first Honda engine, around 11 PSI my FMU was no longer sufficient and I knocked the ring lands off of my pistons pretty quickly. The moral of the story is that a turbo kit can be designed to be reliable and make significant extra power if the owner doesn't mess with it and blow their stuff up. I don't see any problem using a well designed turbo kit to make 5-8 PSI on a stock Honda engine. It may shorten the life of the engine, but I think that with good maintenance it will last for many years.
