resently i bough a beater a 1990 integra ls for 800 $ it has 230k miles the motor still runing strongh no problems no smoke I havent done a compr test but i will soon my question is would u boost that motor to like around 5 to 8 psi ?

Here is what people will tell you:

1.) Do a compression test
2.) Do a leak down test
3.) If 1 & 2 turn out good, boost it.

Boost it. If shes too worn and blows then rebuild after that!

EK FLY

do u really think it would happen something at 8 lb ?

Boner_Ben

Anything can happen what are you going to tune the car with? 230k is alot of miles, but if the compression is alright then its irrelevent.

Think of it this way, if you knew a girl that had un-protected sex with over 300 men, and after those thoughts you still wanted to have sex with her, wouldnt you think about doing some tests before you just see what happens . JMO

zeroice

good example

yeh same exact situation lol

but seriously, just boost it, whats the worst that can happen....it'll lose compression faster and you'll need to buy a new motor, right?

well if the motor isn't good now, you'll either need to rebuild it first or buy another. So basically you can't lose, just do it!!

Regardless of mileage ^^^. I've boosted a few LS's w/ over 100K and one w/ over 200k. No issues except traction problems

Just do it. I just boosted my LS with 218,000 miles and she is running perfectly on Uberdata at 7 psi.

**** man, all I ever do is boost the **** out of old *** stock motors!!!Must be a long string of flukes for me huh?? haha

boostedcivicsir

if i try that stuff, i usually weld pistons to wrist pins.

I'd watch out for the rods letting go with that many miles on the motor.

redzcstandardhatch

it'll be fine well tuned, lower psi.

its been done...

any engine can let go any time though, once its pushed a bunch. sometimes there are weak links to an engine. not too common with honda's though...they are TOUGH for what they are.

a buddy of mine made 230 whp on a 200K d16z6 block.

beerbongskickass

The LS rods are different than the b16/gsr rods. The design of the big end puts all the pressure on the rod bolts.

blackeg

id boost it. tune it well, 5-7 psi, your fine. i boosted mine at about 205k, and it was still running perfectly at 215k when i took it out
