Hi everyone,

Ive tried search for this but nothing comes up, I just wanted to see what your views were on the above. Id like to put some 9.0 compresion pistons in there and run around 500whp. I Would have expected this wouold suit more na aplication, but im not to sure?

Any info would be appreciated...

 

and what is your question?

Can you do it? yes but if something goes wrong there is no room for rebuild

 

there be room for a rebuilt but for another turbo built probably not

 

I bored my sleeved B16 to 84mm, just in case anything happened. I had a boost controller problem at the track and melted the pistons a bit, requiring a rebuild and a bore to 84.5mm. I ran it at a bit over 400 WHP, which was as much as I wanted for a car that I mostly used on the street, but it could have made 500. I drove it for a few years until I sold it to somebody, last I heard he was still running it. Like others said, go a little smaller so you have a bit of room for error, you may need it.

 

i have one check my sig not tuned on dyno yet. im going in a couple of weeks. and i think i have plenty of room to go on my sleeves. you can still go to a 85.5 or a 86mm.
