Well I was reading another post about this but it did not go into much detail and I searched but no results. Ok can anyone give me an idea how long a 5th gen lude will last when being boosted on stock internals? Also I see alot of people talking about 7-8psi on their cars saying it will probably only last around a year. What will last around a year? The engine? The turbo? can anyone be more specific and get into some more details about boosting a stock engine. I'm sure there is plenty of people like me who are saving up their money to turbo up their prelude but havent thought about other things and pretty much are just too impatient to start from the ground up. Again this lasting a year thing are you guys talking about the engine? Wondering because im wondering if I should find a 5th gen that has had the **** driven out of it instead of investing in a 99 that has 75k miles. Dont want to blow engine after a year. Any feedback will be greatly appreciated.

search harder.

there are tons a threads addressing this issue/issues in great depth.


but, blowing the engine is what they are referring to. if not properly installed and tuned, you could blow your motor in seconds, literally. knowledge is the only thing that can help prevent the situation of something going wrong on a boosted engine- and eventually, something WILL go wrong.

 

it's the engine. the ringlands in particular. you should be able to find mountains of info on this. especially if you look on PreludeOnline.com (if you're a member). any luder who never plans to build the block relatively soon should not go with forced induction, unless you only boost like 4psi, which is pretty useless.

 

There are plenty of good threads here, on honda-tech
that apply to these situations.

The ringlands are one of the most common problems when turboing
h-series engines like said before.

I've never had a turbo honda myself but I can tell you this,
good engine management is one the most important factors
when it comes to the longevity of a motor.

haha, word.

 

Well thanks for the input but yet again still no answer. I want to know for the sake of knowing =0) does anyone have an estimate of how long a stock 5th gen with a turbo kit running 7-8 psi will last? Also .... what are ringlands?

i have a very good idea.........depending on what system you use to tune it, and how well it is tuned, you've got anywhere from 3 months to 2 years. i'm sure people have gone less than 3 months, and i'm sure people have gone more than 2 years. the question is too broad. there are way too many factors that affect how long the engine will last. how many miles is on the engine now? what are the compression readings now? what size and trim on the turbo? what boost? what's the fuel setup, and are you knocking any? do you get on it a lot?

see, there is no cut & dry answer for the question you asked, and that's why no one has answered it yet.

 

You can definately boost more than 4psi I think.
I've been boosted at 9psi for 2 years and my car is daily driven with no problems at all *knock on wood*. Doesn't blow any smoke or anything, and I made pretty decent power. Its all in the tuning. If you have a good tuner, reliability should not be an issue.

wow! that's reassuring to hear. do you have a stock block? what are you using to tune? your results are irregular, to have it last that long, especially at 9psi. congratulations. But i wouldn't expect mine to last that long even on 7psi.

the reason you're not getting a real answer is because you're not asking a real question - no offense - your question is way too broad. there are too many variables in determining how long an engine will last, there's many parts to the equation of finding out long an engine will last on boost - and you haven't given any of those variables - like what is the condition on the motor in question, the fact that it is a h22 isn't enough info - mileage, compression, leak-down, etc plays a role, then you a say a kit - which one - there are some kits out there are good and somewhat reliable, while others are not. nearly all the guys i know that are running boost, are custom set-ups, not kits, they include higher quality parts throughout, and if it doesn't lend itself to higher reliability, it at least lends itself to higher performance. the generic answer to a generic question - all things being equal, the two largest factors in lifespan of your motor on boost will be the knowledge of the installer - to make sure everything runs mechanically correctly, and then the knowledge of the tuner - to make sure everything runs safely and efficiently.


the more you search and read - which will yield the answer to your ringland question - you'll being to learn how long a turbo'd motor should last when considering all the variables on that specific motor.

good luck.

 

if you want an answer its not gonna last too long

Yah its a stock block.. I just go the car i dont know the compression ratio.. its a 99 hona prelude s, manual, with 75ks on the motor.. not mods at all.. 1 driver owned it and was an older guy in his 40s... in very good condition.. was just wondering for a guestimate.. thanx for pointing out the obvious about there being many different variables.. that i know.. what i dont is i dont have a clue about turbos and longevity of them being used let alone being used on a stock block.. i have never gone turbo but i enjoy the car alot and have been saving money hoping too.. was just looking for a guestimation of give a take o year or months.. nothing exact.. thanks anyways

It's most likely 10.0:1 compression.

anywhere between 5 seconds and 5 years. there's your answer, just a rough "guesstimation". you know, give or take a little.

like mentioned above, search this forum for info on how long a stock block will last under boost. its been covered. my guesstimate for you is that you are going to blow your motor... that's just based on this thread, its nothing exact, just a guess.
