I wanna boost my bone stock Z6 at 8psi but its got 256,000 kms on it. You think that the high kms on the engine will push a failure? Should I not bother?

 

Use the search bro..


Compression and leakdown tests are required for higher mileage motors. Get those done, and go from there.


Or if you have a second mode of transportation, and don't give a **** about the motor in there, just boost it. If it blows it blows right? z6's are like $300

 

do the compression test, 10% between the 4 cylinders. if youve got that then boost away. andits a honda, you can run it for a million miles if you want if you take care of her. and like forty said, if she blows, drop a $300 z6 in it. someone you know has to have a spare car for a week

apparently i just learned that torque kills engines, so go with a big turbo that puts out lots of hp with not so lots of torque. if anything goes wrong its probably gonna be a snapped connecting rod. has the car been pounded on its whole life or been treated nicely. that makes a difference too, my buddies celica gsr through a rod and his motor is basically stock with only 90k on it,just cuz he beats the **** out of his car.

 

Ill run a comp check tonight.

The car has been driven nicely untill I got it a week ago, I drive her hard but have only got up to VTEC maybe 3 times, I shift at 4k rpm every time cause im scared of the high kms on it.

I was thinking of getting a T25 for now while its a stock plant.

But Im collecting parts to build up the engine, ARP's, Valves and springs, Gaksets, Pistons and rods, rings/bearings, hone, clearance checks and then Ill upgrade the turbo to a GT28RS. Of course ill upgrade the fuel system also, and maybe new axles and an LSD.

 

Cars are like people. A Person can die at 60 years old from being an alcoholic and a chain smoker. A person can live to be 90. it's all about how you treat your car. My brothers old cavvy pretty much crapped out at 150kms. get yourself a compression test and whatnot, and see if your cars eligable. i think it would be better to get another block, and build it up. FOr 300 you can't go wrong, and you can get one with alot less kms.

 

True, but the only way Id do that is if I find surface warpage. However, it would be nice to add things to a block on a stand and not have to stress about doing the whole project over a weekend, so we'll see.

 

Sov had a D16y8, and he kept it in his car and built a D16z6, it gave him enough time to do all the work, so you should look into it. But yea, You can't exactly expect things to all work out in a weekend, cause it could take weeks, if something doesn't exactly go as planned.

 

hey if it blows get it on camera id like to see

 

^Not gunna happen. Im not gunna just waste my engine like that.

 

I made an account for the sole purpose to reply to this, my D15 has 550,000 kms+ aswell with the original transmission and she barely burns oil and I'm revving past 4k rpm even to 6, and I beat on this motor day in and day out.. All my hondas are well pass 400,000km all with their original non rebuilt motors / transmissions.. I don't see why or how your worried about a low km motor.. Unless it's mistreated it shouldn't be going anytime near that low number.
