Depending on the goals/turbo sizing. A smaller turbo making more boost down low needs less compression.I'd run stock compression. 9.5CP is fine. you can get it lower through MMR for sure though.
Why not MMR, Ive seen a lot of good things from them on this forum. And for the price you cant really beat em. I spent the money on a Livernois block and it was nothing but problems. I could have bought 3 MMR blocks for the money I paid.Modmax or Excessive motorsports...dont go through MMR
good to know, thanks.1. Well they put normal gears when the customer asked for billet so that engine blew up.
2. Another guy had a longblock built by them built for 800rwhp and he had valve float at 5200rpms bc they put stock cam springs in the heads and not 125lbs springs.
3. They suggest moly rings for higher horserpower cars
there is more but I cant remember all of it
And they say 3 technicians sigh off on all of this?? please.
