twin turbo set up

http://cgi.ebay.com/ebaymotors/CHEVY...VW#ht_4439wt_0

what does everyone think of this? 1600.00 seems a little to good to be true.

Thanks
Matt

they are all knock off parts. Theres a few people that have used the cheap turbos and work, but kind of keep in the back of your head that its very bottom of the barrel stuff that has a higher chance of the parts failing.

* Looking at the feedback...i'd steer clear.

i read most of their neg feedback

That seems a little too cheap if they used quality stuff. But , hey it might do good. My buddy thats an engine builder built a dual turbo water-after cooled , fuel injected 406 this summer and it was 40k for the whole thing.
They do have a few neg feedback, but , looks like they fixed the problem after they got blasted on E-bay.

For that price, it seems like a good starting point at a minimum for a cheap motor. Research over on theturboforums and see what people are saying with this stuff. One guy has two of those chinese turbos running on a 396 I think and has had good luck so far. Ive got a few chinese wastegates and bovs from ebay and they are real nice pieces, I dont know if they work long term though.

edit: Notice that kit is $1680. You can get the same kit but with internal wastegates for $1480. I'd rather have internal gates on small turbos like that anyway.

40k? I must question this because it seems really out of wack. Hes an engine builder (meaning he can do some stuff himself) and yet he dropped 40k? Is this like a 7 second car? Details? Pics? Im very interested in this.

Think about it for a minute. All the forged parts in the 406 bottom end to make live under boost, good heads and intake, custom headers and downpipes, AND dual air-to-water intercoolers, I can easily see that going to 40K for the whole drivetrain, trans/convertor and rear included.

And the thing with air-to-water intercoolers is you have a heat exchanger and pumps with lines for both... It all adds up. Not to mention the price of the turbos and all the little parts to make it all work...

I could find a pair of TA-49s for Jason's Nova and we could probably make the stock bottom end 355 live at 7psi for a long time in his car. It'd probably be $2K or so, most of that being in the headers and suck. Then we could do a DIY alchy setup as well...

I have thought about it...thats why I ask. Aftermarket block/heads, all forged parts...you could blow $10k on. And you probably could blow another $10k on a twin turbo setup. I dont see how you can blow $40k though. $20k on a engine and turbo setup you should be able to make 2000HP.

Think about it like this....How many B.S. crate motors are going for over $8000-$10,000??
Now think about how many engine shops are selling complete engines for $20k-$30k??
Now add the turbos and plumbing and hardware...
Remember, there's a pretty good handful of standard 23* heads out there that once you install an extra $1000-$1500 worth of Titanium valves and another $2000 for the custom big named port work will put you in the $5k range JUST IN THE HEADS!! Now add another $500-$750 for the port work on the intake (unless it's a sheetmetal )...

I can definitely see $40k for just the power-plant....
Why not..Some of the Outlaw boys I know have well over $60k in their nitrous snorting BBC combinations and that in NO WAY includes the Bruno's and Fab-9 rears, shifters, CO2 shifter systems, electronics, etc...

Most of my customers spend 10,000 to 15,000 on turbo, wastegates, electronics, efi, fuel system ect. Quality stuff isn't cheap. It is very easy to get 30000 to 40000 wrapped into a engine turbo combo.

some quality stuff is cheap. You must have a lot of customers with 7 sec cars.
