can my engine handle this

[zack420aspeeder]

i have a 95 eclipse rs it has about 130k on it and im wondering if i could run the 6-7psi on it wit out killin it or hurting it badly or should i just spent the money i was going to use to boost it to rebuild it

I think those questions are best answered by several tests, the first of which I would advise is a compression check to see how healthy the bottom end is.

The true answer to your question depends on how much wear your block truly has been through.

 

[zack420aspeeder]

well ik i have ran my car pertty hard since i have owned it but i think i will get that check

On a healthy stock 420a 10psi is the safe maximum I have seen personally. I have seen 12psi but it is pushing the limits.

 

[zack420aspeeder]

well im hopin i can just boost it and not have to worry about the internals that much

 

[mightymousestd]

do the compression test and pull the valve cover off to see how the top of the head looks...good stock internals can hold 8 easy...I used to have a 96 std that would run fine under 10lbs at the track, 5psi daily, put the turbo on at 136000 and ran fine til I got rid of it at 164000

i think i will take a look at it in the morrning i have to change the slave anyways today

I agree here, my motor is fully built and i run between 10lbs & 14lbs depending on the situation.

Don't do it, IMO. For example, my motor had approx. 65k when i installed boost. 3 months later i blew my piston rings. I was only running 6lbs of boost. WTF

Every engine is different. The best answer is to build an engine to handle it. But, some people are fine trying boost on the stock bottom end.

 

[zack420aspeeder]

well if the test are good im goin to do it or i can buy a talon for 800 and biuld its engine up for boost

 

[shawnmr]

130000 isnt much if you keep up on mant. ,u can tell usaaly how strong your motor is i would think it would hurt

hey man, I have a friend that has a 1g with 200K on the motor and he is running 17lbs on the stock bottom end daily driving!!!. Just make sure you run your tests. Im not sure what he has done to his heads, but I believe they are stock as well.

On a 420a motor ??

1G's didn't have 420A's in them. He's prob blatting on his friend's 4G63 which he didn't mentioned which 1G model it was.

 

[dsm-onster]

Can't be either, because he said "headS"! . . . Unless he doesn't know what he's done to his brain and other member. Yet, neither will make a car handle more cylinder pressure .

buy a gst and be done with it.

This answer always fustrates me. I understand the concept, as I have an RS that I'm debating constantly if it will be worth it or not, but I also know it is the spirit of tuning to take something for cheep and invest in its future.

If I could afford a GSX which wasn't in trash condition (or everyone for that matter) I don't think anyone would be driving a RS, GS, or GS-T.

so go to a 1G. they arent pricey if you look around and for the price you bought your car for you could have a nice lil street machine

well now im haveing problems wit the tranny i had thought the slave had went out but i changed it and it still is not getting presure to the peddle so can anyone helping me wit this problem now

 

[doober75]

Where there's a slave there is a master. Check the whole hydrolic system. . . Please don't fncking type "wit" anymore. H is right in between G and J on the keyboard.

This may be a dumb question but is easily overlooked, did you bleed the line??
