I know there is a company that makes a small twin setup utilizing the stock turbo maybe with an upgraded exhaust side? Whatever it be I was wondering what the smallest amount of fuel is that you guys with a small twin setup have ran and still had good daily driveability. I will be going from here- (soon) flux 1's, and a mild cam (new springs probably a little heavier), boost fooler, walbro pusher pump. I was wondering if I could just run maybe a pressure box to turn the turbos. Also what other benefits have you all gotten besides low egt's and power? Any boost in fuel mileage or at least not a drop in fuel mileage? I'm really thinking about doing this in the near future, or when I get enough money set aside, I'll be doing all of the work too.

yup nathan at MPI has very detailed beautiful looking piping , best looking setup I have seen.

I am really excited about my MPi twins nathan & I are installing on my truck next week HTT 62/71/13 ss S485 got your seat belt on ? LOL......

when we get done I will post some pics of my motor with the new turbos

You should be able run a small set with those *** 1s and a pressure box. I would recommend something like the Quad xzt that does a little pressure and a little timing. It's a very nice inexpensive box. But Nathan at MPI would be the one to answer your question.

thanks a lot fellas I'll give him a call, and come to think of it, I believe it was the MPI twins that I was thinking of but couldn't remember the name.

Yep, Nathan @ MPI is the man for twins.

I'm not sure you can use the smaller stock '03 turbo in a twins setup though. I'm sure you can, but not sure how long it will last since it's quite a bit smaller than the later '04.5+ turbos. Nathan would know for sure.

I've run my MPI stocker/S400 twins with all stock fueling (stock programming and stock injectors) and, while they weren't exactly quick to spool, I could drive it around like that just fine. The stocker/S400 setup does great with stock programming and the Flux 2's (100hp) though. I wouldn't worry about being underfueled with that setup.

Seems like I've seen quite a few stock turbos for sale in classifieds, $200 or $300. I don't remember if they are the HY9, but I bet they are out there.
I remember a stock turbo (assuming 4.5+) over a GT42, it was for towing had 2 wastegates, good for 550 hp or a little more (can't remember exactly).
X2 for Nathan at MPI, beautiful work, packaged great, complete package. Can't go wrong with Nathan!
