I know the topic comes up time to time, but they always seem to turn into bitch fests or someone saying why would you..

I just want to know if anyone has actually completed a build on one of these..

I was thinking LQ4 that I have with a noticable rod knock + 4.8 crank and later floating pin 4.8 rods + forged pistons + turbo cam in my current setup would make for a fun screamer when you turn the boost up.. Just to hear it wrap to 8500 every now and then would be fun.

Yes I would have it all balanced and yes the machine work would be more than another JY engine.. Just curious..

Post up completed builds and power made / times.

Thanks,

Here is something for you to take a look at:

Unless you plan to spin it past 7500rpm and go solid roller I don't see any need to run a 4.8 stroke crank. A stock 3.622" crank can handle that rpm with quality hydraulic lifters. Hell I did it on ls7 lifters and routinely spun it to 7800rpm. The stock cast crank eventually failed after 15-20 1/4 mile passes, probably 100 freeway pulls, 30-40 1/2 mile ***** to the walls 1000-1200rwhp blasts.

Also to make power past 7000rpm and not hit an airflow wall (power flat lines) you need a serious intake manifold and properly spec'd turbo to support it.

Red Headed Screamer is the build I saw that made me want to do this.. I will start gathering parts slowly and just go ahead with my plan.. Just a dyno queen at the high HP levels.. It won't use half that much power on the street being a car/truck
