Hey there....
It seems pretty obvious that turbos are the way to go if you want to go fast..
Would I get any good results using a turbo set up from a 5.9 cummins ?
Or if I have to go trough the whole 9 yards ?
I don't know much about turbo, that's why I'm here
I have 10.8 cr and Indy heads ported

The HX35 just isnt enough turbo for a healthy V8 gasser. Using a pair of them might get you some reasonable power though, there are just way better turboes out there better suited to a gasoline V8.
Mopar to the bone!!!

Didn't Cummins use several different size turbos on the 5.9 CTD? I agree on not using just one designed for a small C.I. low RPM diesel motor on a car motor on gasoline with a lot less heat in the fuel to drive the turbos. It is probably way better to have more boost than you really need

If you got the compression down to 9:1, you could easily achieve those numbers with a setup like I use. Magnum exhaust manifolds and a Borg Warner S475 ($650 turbo) would get you there easy. You MIGHT be able to do it with one of the cheaper Chinese knock offs, but there aren't a ton of them out there with large turbine (exhaust) sides for a motor as big as a 408". You might choke the motor on the turbo before you get where you want to go powerwise.
Poly... respectively... A 71/75 would not make 1000hp on that motor, and you can find something that would work for a lot less then $1600.
The 408" needs quite a bit more then a 75mm on the turbine side to make 1000hp, and the 71mm compressor side would be absolutely set on kill to feed a 408" to 1000hp.
If you wanted that much power, The S475 I suggested with the 75/88 would be a good choice, or if you wanted more the Borg S480 with the T6 can be had for about $850. This has a 80mm compressor, with an 88mm exducer also on the turbine... Much better match for a bigger motor looking for 1000+hp.
The borg stuff is slightly on the heavy/large size, but they are about the best bang for the buck out there, and they are about bullet proof as far as turbo's go.

About the cheapest turbo off a factory rig would be off a Detroit. Its a Garrett TV8101. The one I had was 82mm. They will get to the 1000 hp range. Would work well on 400-500".

I actually have one of those I got from one of my customers years ago, what a heavy piece. The one I have is in pretty bad shape but it was free so I snagged it.

Viren (VS racing) is obviously getting his stuff from overseas like other distributors, but I have to say working with him he's a very good/honest person. Not a guy I'd be afraid to buy from. His S480 knock offs are about $50-$100 cheaper then the real thing, BUT come with a billet wheel too. So it really depends how good the billet wheel is if you want to risk buying one. Really too new to tell how much better they are then a regular cast wheel S480.
I have considered selling my single and going with a set of twins from VS was looking at the billet 78s. But I am also considering starting over with a R5 so I don't know.. lol
