Whats up with the $900 twin turbo kits on ebay for 5.0s? how cheaply are they made and if i got one how long do u think the turbos would last? also once they went out couldn't i still buy two used quality turbos to replace them and still come out a lot cheaper than a really expensive twin turbo setup?
Also what other things would have to be done to my car to run turbos? After reading on a lot of sighs tonight even if i dont get that one i think i will piece together a turbo set up, it can be done pretty cheaply
They are junk. From what I've seen, when assembling them nothing goes together right. The turbo mounting flanges quite often need to be hacked off the headers and re-welded as they are misaligned from the get go. The quality and thickness of the steel is quite often of suspect quality and a bit on the thin side. Don't forget too that those $900 kit's won't include downpipes which you'll need to fabricate yourself. The also seem to include small intercoolers which won't be able to support the horsepower levels most people will want to get out of these kits. The turbo's themselves are typically of extreme cheap quality…and while they seem to work from the get go, they often fail in the long run. Unless your picking up used turbo's off of OEM vehicles from the junk yard…your going to be hard pressed finding cheap turbo's that are of any quality. In the end…if your looking for cheap, you'd be better off starting with a set of quality headers from the likes of B&G and building everything yourself.
You will need to spend more than $900 just for the tuning aspect of a twin turbo setup. You would need a bigger MAF, bigger injectors, a Tweecer or equal, a wideband air/fuel gauge, a bigger fuel pump, and some dyno time. The $900 would be the tip of the iceberg...
