I wonder how long these blocks last with a decent amount of boost 10-15psi.

 

The same reason I want laskey cuz is in ca. I prefer inlinepro but more than likely, I will go wit laskey

 

My builder (very reputable and knowledgeable) recommended to break in my fully built long block that he built with Mahle 87.24mm 9.5cp pistons and a fully built head on the stock OEM ecu. I had Kpro, so that wasn't possible, but I just used the Kpro stock map. Granted I tuned the fueling on it but I left the ignition alone. Babied it, and when I took in for a tune after about 400 miles, my low comp F20C made more power than many stock F20s (212/146) on what was considered a 'normal' dyno for my area.

 

in CA, id check out mission critical performance

 

I ran a 9.5 compression 2.2 block with stock ecu for 3000 miles break in before boost. Seemed to be ok. Motor is still strong at 20~22psi 3 years in

 

A few tuners I spoke to said it was ok to just break in motor with stock ecu and not WOT the thing. It drives pretty good. Doesn't idle funny and starts right up. Im at 50 miles or so. I have an issue with my car dying out though. Don't think its an ecu issue. Im thinking its my alternator giving up. By the way how much hp are you running and what kit?

 

Made 503 on the dyno just to break 500 then backed down timing a bit for actual use and made about 475 on pump. Never did a race gas tune on this engine yet
