i just put a 92 cummins in last week in my ford with fuel mods.the turbo lags and has high egts.it has a fuel pin,370 marine injectors and i maxed out the pump.it also has gov. spring.i think the stock turbo is to small.what size shuld i go with?

 

The old school 370s are a 5X.012. That's a bit of extra fuel. That was the set up my 91.5 had when I bought it, 21 cm2 exhaust housing included. The EGTs, however were not much of a problem. When I switch to the 16cm2, then EGTs became a concern though the lag went away. You can upgrade your H1C, but there are other "cast offs" from newer trucks out there for the same price or cheaper.

 

I would go with a HE351 off a 3rd gen. The stock hc1 is to small for those mods.

 

before people go recommending away in the blind let me ask you a question

what do you want to do with the truck?

a street turbo wont be good for the track a track turbo wont be good for towing ect ect

so make up your mind on what you want to do and then we can get somewhere

 

You don't like us cummins forum guys to much do you?

 

has nothing to do with where your from it has everything to do with helping the guy get the right parts for the job

 

Well considering he put it in a ford I highly dought it's a race truck but your right I shoulda asked what he was going to use it for first.

 

Brice you and I aways seem to **** people off on here. LOL
