Hi fellas, I have been searching for info on stock stock sleeves and boost but I couldn't find anything about a high mileage motor with stock sleeves and boost.

I was just wondering what kind of power I will be able to hold with forged internals, low compression, and a good tune on a motor that has stock sleeves with approx. 140,000 miles on it.

Thanks.


p.s. I am sorry if this has been covered elsewhere. I did search before I posted.

SLEEVES arent really affected by mileage except for bore wearing smooth. REHONE IT and go!

Cool, I was planing on rehoneing it anyway.

Thaks.

Anyone else have some input.

you might need to bore it because sometimes the sleeves get egg shaped after that many miles. just have a machine shop check them for roundness.

we just turbod my brothers LS with 140k miles on it, stock, got it stoopid tuned and it put down 254whp @9psi on a conservative dyno(ultimate/machv performance).

my cousin has a b18a with a built head but stock bottom end with over 230,000 miles on it and he's boosting 7-10 psi.

As a daily driver I would keep the boost low (7-10 psi) but when I go to the track I would like to take it up to atleast 17.

Do you think that would be problem?

adseguy

why is 17 your exact number...why not 16.5 or 15 or 20......think.

TheAntiRice225

It's not. The # 17 was just to give you guys about the area where I wanted to be.

turbo will most likely be an sc61 btw.
