stock sleeves, you will need to find a really good tuner

i don't know much about the turbo, might flatten out?

good luck you might want to start looking for another block now

donkiman

is the turbo capable of 450hp? because if it is then yes you prolly will. how long will those sleeves hold up.... even with a very very good tune i cant see them lasting too long.

if you wanna make that much power why not just have it resleeved. open deck sleeves from darton are only $625 installed.

I used a 62-1 but on a T4 flange and made 627 at 28 psi,but the motor was sleeved.

mattcalica

i think he means the motor is sleeved, but retains the stock bore...not sure though...if the turbo is capable, you should be able to...just get a decent tuner.

62-1 is definitely capable of producing the numbers

You might look at a Dart block. Sleeving costs about a $1000, and the Dart block is $2250. You get an entirely new block with a closed deck, bigger water passages, and reinforced main seals. So all in all it costs more, but its a completely upgraded base to start from.
