Custom front mount single turbo setup for sale

I’m seriously debating changing my turbo setup to twins so my front mount single setup is up for sale. I built the setup myself; all piping is .065” thick 304 stainless from Stainlessworks. The manifold flanges are from them as well and are 3/8” thick.

Asking $2499 obo Shipped in the Continental US
Open to reasonable offers :cheers:

***Does not come with cold side piping, intercooler or bov***
***If I didn't list it above, it does not come with the package***

I’m not sure how I would ship the downpipe as it is; I would probably have to cut it into two pieces, but should be easy to reassemble.

I’m fairly certain that this will fit on a fullsize truck and took a couple of pics with a measuring tape for reference. If you need any additional measurements or pictures, just let me know.

If you want to see what this size turbo is really capable of, do a search for CurtD on performancetrucks.net…he has one on his truck with a built 5.3L running 12.0 @ 120 mph, making 619 rwhp and 657 ftlb PerformanceTrucks.net Forums - Dynoed today

cool setup, wish it would fit a truck... very nice work

It probably would, if anyone needs some measurements to find out I'd be happy to take some. My buddy has a 2000 Chevy truck that I can measure against to make sure. The one thing that might need some tweaking would be the downpipe where it goes between the frame and the firewall, but that should be pretty easy.

do that man, I might be interested if there's clearance, the downpipe is no big deal I could fix that easy.

Took some measurements off my buddy's truck (2000 Chevy 2wd, 5.3L)

Obviously the fan shroud and clutch fan would have to be removed, but there would be:

3/4-1/2" clearance between the end of the wastegate and the radiator core

2 1/2" clearance between the down pipe and radiator core

1 7/8" clearance between the wastegate pipe and radiator core

On his truck I measured about 12" from the drivers side edge of the alt/ps bracket to the battery. My turbo setup sticks out about 5" from the edge of this bracket without the air filter. With the air filter it is about 12".

The downpipe might work with a little modification where it approaches the firewall, but some of the heater hoses would definitely have to be rerouted based on what I saw on his truck.

So overall I would say this should work on a NBS (99-06) GM fullsize truck with modification to the downpipe, heater and possibly a/c hoses and removing the stock fan setup. Additionally, his pcm was mounted next to the battery sort of above the frame rail. This might need to be moved a bit as well, but it depends on if you used the same airfilter or not.

Hope this helps.

I'll have to think about it, I'm not going to sell it separately just yet.
