He351cw help

[92cummins89]

I just pulled off my old snail last night and am lookin at puttin a he 351 cw in a few days
There anything I need to look out for or is it bolt up an go ??

Gonna have to drill out the ( i think its the top two) hole in the manifold a little bit in order to fit the 351 studs threw it, along with the 4in. downpipe, and most likely going to need to remake your intercooler piping to the turbo
Worth it in my opinion

[BILTIT]

You need the specific flange for the downpipe.

If i recall correctly the compressor outlet is 2.75" so you will need a reducer hose to fit your intercooler pipe. Also, a way to block off the solenoid port if you do not have the stock solenoid.

Other than that your golden.

im gonna order a new exhaust 4 inch with the flange
i have ic pipe from an 06 dodge so that isnt much of a problem

wat solenoid are you talkin bout

[BILTIT]

The "command valve" in this picture. If you do not have it then you need to plug the port as you can see in my picture above.

Wat did u use to block it off ??

[92cummins89]

Or wat do I need to connect my pig tail too cuz mine has a waste gate an the solonoid on mine already or do I just take it all off

I'm not sure how to post a pic of wat mine looks like

[BILTIT]

I bought this plug:

But if you have the solenoid than keep it. With no power connected the wastegate will open at 20psi and with 12v on the solenoid it will open at 40 psi.

[92cummins89]

Would I just wire the switch to the ignition ?

[BILTIT]

You could, then it would always be set for 40psi.

[92cummins89]

Y would u want to plug it an only b able to achieve 20 psi ?

Don't u want more boost I been lookin around seem lot of ppl plug them

[RCCUMMINS89]

I ran mine on a toggle switch......therefore the solenoid is not always activated when vehicle is running.

If you run that same toggle to some sort of valet switch......you have both the turbo and fueling working in unison.

[BILTIT]

Its an option, for unloaded running you wont need anymore than 20psi very often. As RCCUMMINS mentioned it would be a nice de-tuner with a valet & wastegate solenoid on a toggle for those not used to the power of a diesel (wife/kid/friend). Might also be good for a summer/winter setting.

I am interested in a working solenoid if you do not use it, it would make for a great summer/winter option for me.

[92cummins89]

Think ill keep it an run it to a switch
Gonna b my pulling / haulin truck

Gonna stick it on this evening

So when the the solenoid is on = 40psi
Off=20psi ? Correct

[RCCUMMINS89]

Correct.
