I have a f13 with a 112 lsa 4*
Patriot 59cc heads

This is around 11.1:1 compression ratio.. i know this is bad for a turbo.. my question is can I get away with running the turbo on top of this for about 6months? I just want to make about 500rwhp until i get the money to forge the block. I will then get reverse dished pistons..


If not Im thinking about switching the heads out to maybe 64 cc or or 68... The problem is I want to run nitrous for about 2 months before the turbo gets here. then be able to put it on and play until i get money for a bottom end..



What about the cam itself... I was thinking 112 lsa was really bad but the turbo guy i talked to today told me it would be fine???? How much power will I lose off the turbo with thise cam if it blows through the exhaust?


About how many hp do you lose going from 11.1 to 10.1 on a natually aspirated and nitrous setup... all other being the same?


thanks

Im thinking i should probably trade in the heads for 10.1 comp and the cam for a 114 lsa.... Im sure I would make good power off that with a 150 shot for the next few montsh.. Then be ok with turbo for 6 months on low boost and then I could forge the bottom and go to about 650 being my end goal.... turbo would be a 76mm.. from mount..


thanks for the info.. sorry for being so sparadic..

thanks for the link. it helped a little. I was thinking I was right about the cam not sure why he told me different.. Like I said I know the compression ratio is bad... but Do you think I would be ok for a while with low low boost?

not ideal, just use the highest octane and take out alot timing

thanks... after thinking im going to be a little smarter about this and take a few weeks to read and go from there. Maybe I should just let the turbo sit here until I get things straight.

thanks

Sell those heads and sell the cam. Get some 6.0l heads, some good gaskets, with the extra money get a cam sized up for your future setup... and you should be set for awhile.. But that's just what I would do. Hope you get it figured out..
