i have two questions..is a turbo 400 strong enough for a 91 5.9 cummins? also, is it dangerous to put a m5 fuel pin in my truck? i know i would have to run a pyrometer

 

What are you going to do with the truck?

 

its going to basically be drove around and it wont hhave very much hauling to do

 

Drove around at the dragstrip, a 1/4th mile at a time? Or, at the pulls, 300' at a time?

Or simply a daily-driver / play truck?


- There are a number of turbochargers based on the 400 frame.
- IMO, the M5 fuel pin is a smokey proposition. Go M3.

 

just a play truck

 

What is your power goal (how much money do you have to spend on the thing)?

- Spend your money wisely . . . . . once.



A reliable and cool (EGT wise) 400+ hp costs more than 350hp.

Does your truck have an intercooler?

 

no it doesnt have a intercooler. are egt's exhaust gas temperature? im not sure how much im going to spend on the motor because im putting it in a 84 chevy and have a lot of other stuff to pay for before i start buying parts for the motor

 

I dont have a answer for the fuel pin... but as for the trans yes it will hold up if its build... I did a 89 chevy suburban conv. i have the th400 i tow a 12000 lb toyhauler loaded and it holds up great. if the trans is stock it wont. i do my own trans work. i did 7 forward clutchs 7 direct and 4 interm. use 4l80 direct drum for the direct that way you can have the 34 elm. sprag. deep pan is a must. and a big cooler. patc trans parts has the kits to help you stack up more clutches! use a 4l80 band and anchor pin. dual feel the direct drum and your golden.....patc for parts and jakeshoes also has a write up on dual feeding a th400..
