turbo help
 

I am looking to make 450hp with my 97 12 valve. It is a 215 pump here is what is done so far. AFC mod, 4k gsk with valve springs, 5x.014 sticks, #10 fuel plate, timing is set at 17 deg right now but will have to adjust when in truck, head studs. The truck is used off road but does see a good amount of highway time, will be pulling a 24' camper less then 5,000lbs but occasionally a heavy car trailer. I am trying to figure out what a good turbo set up would be, would like to do a single for now for money reasons. The truck is fairly light it is an 81 regular cab shortbed f-350 (shortened f-350 frame and one ton running gear) on 38's now.

for a single I would run a 64/68/14 wastegated

That's the size I was looking at any recomendations on where to buy? I really want twins but in the process of buying a clutch so money is tight. I have my original turbo and I can acquire a ht60 to do twins but am really looking for a simple bolt on and run for now.

get one from a vendor on here can't go wrong with them

62/65/14. did 426hp with 5x12's 960 tq with some room to grow. awsome all around single turbo.

Stock HX35's are tougher than most people think. I made 433rwhp with mine, with not much smoke.....

Do you think I will be able to run the stock turbo until I can put some more money togethor with the setup I have? Maybe with some de-tuning sorry not trying to be cheap i'm just poor! I also don't want to damage anything so if I have to wait to get her going it's not a big deal. My main concern with my turbo choosing is I dont want any lag espescially for off road purposes.

5x14's and a stock turbo will be VERY VERY hot! you can run them but it will be hot. and off road i think you will be over fueled aswell. why do you want so much fuel?

you can make power with the hx35 ... but its real sketchy due to the imminent shaft shearing that typically occure or the wheel that pops due to overclocking the wheels ... with the correct timing and a well tuned AFC .. its do able .... but not for a lobg period of time ...

If you were to to @ those loads and such ... you would kill the turbo , probably wouldnt take long ... I'm sure your EGT's on the dyno were 1400* or better .. even @ 20* timing ... do able .. for a short blast though , Knowing the limits is half the battle..:c:

That is what I was worried about. As for the injectors they are not in yet (sitting on the bench) I got them for almost nothing I can probably trade them for a set of 5x.012s
I really want to be around 450-500hp but I would rather be on the lower side if it's going to drastically reduce fuel mileage:argh:
