What is the better route? What was your timing set at? What were your EGT's? What trans do you have? Was your boost levels with a load or unloaded? Do you have any comparison for before and after towing?

I would possibly be interested in the van parts once you get them sorted out.

 

mine will maybe make 10 lbs on a hill empty.
put 21,000 lbs trailer behind it and i will pin the boost gauge on the same hill.

 

10-12 ain't that bad for an untuned turbo setup. Tweek it a bit and you could get more. And like the others said, once it's loaded, it'll bump up a lot.

Also, unless you've done other mods (head studs, etc), you don't want to exceed 12psi anyway.

 

15 on a pure stock engine is fine. you need studs when you hit up around 20 PSI

 

I was happy with 7 with a 8 year old IP and stock injectors

 

One thing I didn't like is there's not a lot of room for a down pipe on my body style (85)
I tried denting the firewall with a 6' prybar but the whole thing just flexed, it's amazing I haven't had to do the clutch master cylinder plate yet, probably due to the fact that I have a smf not a dual.

I'd like something in the likes of 20-25 but I need studs and my motor already has too many miles plus she's starting to breathe a little. I just put an engine in it not too long ago I just went the cheap route until I have the time to actually build a motor.

I think some cowl massaging and a hx35w turbo would match up nicely. They bolt up to the banks pedestal too.

 

This. Also, while the early banks doesnt command the price of the sidewinder, imho there isnt a damn thing wrong with them. All the reading ive done shows they perform really well, and respond very well to a larger compressor wheel. Alot of it i think comes from people thinking a wastegate means a better turbo, where i fully disagree, it depends on the turbo and the engine. As for IDIs, with stockish fueling, i doubt you could tell a difference between an 093 and 088

 

Pull up the turbo and dyno threads and do some research. HX35 is way too small... ask me how i know. An H1C might work alright as it has the 17cm housing, but the turbine is still small and the compressor trim doesnt really suit the airflow needs of a 7.3. If you want to go on the cheap, look for an hx40, s362 or similar off a 7-9 liter engine and run a t3/t4 adapter if necessary, or get an 093 housing machined for a s300 series turbo from R&D
