After months and months of trying to grasp my messed up thought process i finally figured out to ditch the idea of building a lq4 and stick with the 5.3 and go boosted. This is my first time dealing with a turboed chevy v-8 motor. I need some slight direction on what im going to need to do to try to obtain around 800 hp that can be used on the street and of course tracked. I still want to sunday cruise. I will be keeping my 3/4 lowering kit with the reast of the stock suspention. I need fuel system recommendations, as well with tearing down the bottem end and trying to figure out what compression to run, pistons rods, heads, I suppose i have to swap out my cam im using now. I take it i pretty much have to start from scratch. I guess this would be a personal question, but would most of you turboed guys go the homemade route and by a full kit. The kits seem kinda pricey for what a guy gets and it seems like the homemade route would be the way to go. I just need some solid information on where to start. Im not new at building motors, im new to building a turboed motor. Thanks guys im looking forward to here what you have to say.

 

Why build any motor. start with boosting what you have now.

 

I'm with this guy, boost what you got then go from there. I would call up Trick, Joe at Left Coast, or Nelson to find out what setup you would need to run to meet your needs.

 

If your gonna start from scratch anyhow why not do the 6.0. Do you have a block already. Either way if its gonna be built from scratch, a nice set of forged rods and pistons would be smart. Callies a site sponsor could set you up. I would PM Kyle on here he KBRacing for a decent turbo kit unless your a decent fabricator. Rick with Trickperformance.com site also does great work from what I have seen.

 

How much bost can a guy run with the lowest compression stock internal 5.3?
I suppose it would be wise to altleast run a boost cam of some sort, or doesnt it matter as much as a guy thinks. Im running a decent cam right now.

 

Looks like i have to make some calls.

 

A lot of people go over 10 PSI. Its all about the tune. Do some more reading of peoples sigs and you will see some impressive stuff on stock long blocks. And some really impressive stuff on Stock long blocks.

 

Thanks guys i will contact the people suggested and go from there.
