injector swap

i replaced the stock injectors in my 1997 Powerstroke with injectors out of a 1999-2003 powerstroke. those are the split shot type. i have now noticed that the EGT's are about 200-300 degrees hotter than before. what could i do to lower the EGT's that wont cost a fortune?

where can i buy a 3 inch stainless steel down pipe?

i also noticed that the trans is shifting much harder and the trans temp. gets hot quick. it wants to climb past 250 degrees. does anyone know what might cause this?

how much boost can you put out of the stock turbo on a 1997 Powerstroke?

i have heard that if you go over 42-44 PSI that you will lift the heads off of the motor. is this true?

A non stainless DP will be cheaper and will lower the EGT's. The site sponsors at the top of ht e page will have the DP you're lloking for.

YOu new found power in the engine is heating-up the tranny. Get a bigger tranny cooler at least. A custom chip will help the tranny too.

Yep, The turbo is capable of 40+ psi but a stock MAP sensor and PCM won't let you get that high but should'nt blow the heads off. There are a few guys on this site running higher boost #'s. Maybe they'll jump in here and fill you in.

if your tranny temps are getting that hot chances are your slipping it. You want to keep the boost below 35 psi or your turbo will go bye bye.

Dont you need custom programming to run the split shots properly.

That could be the reason for high egts. But your tranny is another problem.

higher egts are cause your dumpin more fuel into the motor. 90cc stock 97 130cc stock 00.

intercooler will help alot and the dp will also. i dont think anybody is making the stainless dp's for the obs rigs anymore. might try banks.

Didn't the 97 CA truck come with 130cc injectors? I would do some research on how ford set that truck up to handle the added fuel. (custom burn)...just a thought. Might be cheaper but maybe not as effective.

all the injectors fit the same. its the internals that are different.
40+ psi has been known to pop the head gaskets on a non studded motor.

the proper pcm code you need is MME6.
although you can run your current setup fine.

splits on single programming ok.
singles on splits programming runs bad.

it probably is not helping any that your exhaust is stock and probably your intake. (not an attack on you)
open those up and you will be good.

your tranny is not gonna last very long just to warn you. get a bigger cooler now!!!!


good luck.
