You really think the stock b16 block can handle 15psi? Daily driven or just for a run down the 1320? I would assume about 8psi would be safe on a stock block, anything else is kinda pushing it IMO. Does head work help out a turbo motor that much? I know building the block will, but like 3angle valve job, cams, cam gears, etc... will that do much for a turbo motor as much as it would for an NA motor?

ARE YOU BOOSTING 10PSI DAILY DRIVEN LIKE MORE THEN 30 MILES A DAY?

If you want reliablity... run 8-9 psi. You want more speed... I have a friend that runs 12 psi daily- but he has a lower compression head gasket... and a block gaurd.
Be carefull with higher boost
Be carefull with higher boost
Here's the trick: you guys are really quick to think that just because someone says "I can safely run 15psi" means that as soon as they let the clutch out, they are spooling 15psi the entire time they are in the car. It's not like that. You can run 8psi daily on the street, and turn it up to 15psi to race someone...That's the beauty of turbocharging...changing the boost instantaneously...

Um yeah that's great... except... the car is not tuned when you just dial the boost up. Thats a great way to blow your motor. Trust me.... I speak from experience-MatT3T4 said:
Low boost *will* damage your motor. You might get a month, or a year or 5 years... but it will take it's toll.
High boost will damage it faster.
Untuned high boost.... you'd be lucky if you get down the street.

A well tuned engine that has a turbo will last just as long as the same engine without a turbo under the same conditions.How is a engine going to wear out faster if it is in perfect tune?Probably buy owner neglect or error.The engines that don't last are either not tuned very well,maintained like shit,or the driver gets dumb and cranks the boost up beyond the engines capabilities.I remember when i first got into building my car (5 years ago) everybody was saying "the engine won't last as long", "it will wear out faster" why because i had the basic i/h/e along with ignition upgrade and t/b.The car probably made 10-12 hp over stock so why would it wear out faster?Probably because some people drive their car like a bat out of hell 99% of the time and then don't maintain it properly (like oil changes,etc).Sure if you rev the engine to (and sometimes beyond) redline all the time it will take it's toll.
Well that engine that everybody said wouldn't last, well it lasted to 102,000 miles (thats 67k miles with bolt-ons) with all the bolt-ons and another 18,000 miles with a turbo.With a total of 120k well maintained hard driven miles.Every time (3k miles) i changed the oil it looked the same coming out as it did going in, nice and clean.That engine is now starting a new life under a friends hood and it will go for another 120k miles with no problems.
So the moral of my long story is it all comes down to how well the car was maintained,driven,and the state of tune it's in.
Now don't get me wrong i'm not saying since my engine held up that every other engine will, i'm just saying that you can't make a blank statement like *boost will damage your engine*.There are to many other factors that you have to take into consideration.

OK, here are a couple things to consder... and if you got these mastered, you should work for honda and devolp a turbo setup for all their cars.b16ahybrid said:
Turbos create heat. Heat wears engine componets faster. There are things you can do to cool it better (oil cooler, new radiator, exhaust wraping, ect) But that is not gonna completely stop the wear. A turbo can create heat in excess of 3000 degrees. I can light my ciggs off my manifold.
HP factor. Some engine componets are not meant to handle the kind of power a turbo can make. Honda has blessed us with good componets that can take quite a bit more hp than stock... but your reducing the safty factor honda had built into the motors, when something goes- its going to go hard.
Parts replaced often in turbo cars-
axles, cv boots, syncros, clutch, flywheel... or just follow the trend... the drivetrain.
Um... maybe you did not read my post. I said... you might get a month, or a year, or 5 years.
It's kinda like having AIDS or Cancer- you have it, its just a matter of time till it kills you. Or in this case, kills your car.
Changing oil, tuning, and driving sensible prolong the life of any car, turbo or not. But you are only prolonging the inevitable truth- one day it will die. A turbo will just speed up the process.
