if i drop 6000 on an engine and race it every weekend ami going to be rebuilding this thing ever 3000k miles or what ? Nobody seems to mention how long differnt particular setups tend to last, any personnal stories would be great

 

imo, if the motor is built right and it has a GOOD tune on it will go for a while.

RLZ built a motor for one of my customers, that motor lasted about 15k miles making 375-400hp. he melted the pistons when he turned up the boost too much. keep the boost a normal level and tune it RIGHT and it will last. this guy beat the **** out of hte car on a daily basis too.

 

First, thanks for the responce when you say somone melted the pistons with to much boost , or when they say it blew it up is the entire engine shot or is it usually only one part that fails , which can be replaced? basicly im just looking for a basic turbo setup on a sohc or dual with 200 WHP , hell if i could match the sensation of 160hp si hatch 02' i drove(which is the fastest car i've ever driven lol!) id be a happy camper right now im running high 16's with my d16y8 96 2 door coupe , i want to run 13.9 thats is my goal (sorry for rambling)

 

man, if thats all you want, then stick a h22 in there with some boltons. you dont need a built motor for a 13 sec car.

 

It all depends on what the setup is and what its being used for.

HONESTLY, there is no set expected time frame on how long a motor should last.
We build many race blocks/engines that are being used for street cars making 400+hp. I'm sure they all dont boost that much everyday and they can last a very long time. Can even be as reliable as a regular stock motor. But then you have these same setups racing once a month that are boosting 30psi on race days. This obviously takes a toll on the motor and longevity is of course not going to be like a stock motor.

The way I think of it is: The motor will last as long as you want it to. If you beat up on it all the time and race it often, dont expect it to last a long time. If you want a reliable motor that you can use for everyday drivign for the next 3-5 years, dont build a 12.5:1 street motor or a turbo motor pumping out 400hp all the time.

With our full out race cars, we do a tear down as often as we can to check the condition of the motor. Since racing isnt our full time profession, we check them usually when there is a big break between events or at least every 2-3 events. They usually are good to go still, but its one of those preventive maintenance things you have to do so you are in top shape at the next race.

 

depends on what you are trying to do. i know of a 12sec n/a motor with 100k+ round here

 

buddy that can depend on alot of things.but like a couple of guys in this thread have told you.....if it is built right and you have a GOOD TUNER......you will have a nice strong motor that will make you very happy....


BUT IF YOU SHORT CUT YOUR MOTOR WILL KNOW..........
