Amg P400

[mikefairbanks]

I guess it's a good thing I've got a day job!

It took me 5 1/2 months, but the truck is back on the road with the P400 in it. Took it out of the shop under its own power for the first time yesterday. In my own defense, it did take 3 months to get the new long block to Alaska!

Thanks again JetBoater for going there first, and giving me the information for getting the oil pan rail. The oil pan turned out great, and holds 12 qts.

I did not end up installing the phazer gear drive at Bill Heath's recommendation. I'm running his new P400 cam, and he felt strongly that I should stick with the chain since that's what the cam was designed for. (anybody interested in a "new, never used" phazer gear drive)

I went ahead and did the DIY CAC too. On my test drive yesterday ambient temp was about +10F, and my IAT was +22F.

Only 50 miles on the new motor at this point... but it seems very smooth, and has tons of power right from the start. Haven't put my foot in it yet, or done any pulling. But am looking forward to camping season this summer.

Congratulations on re-powering your truck with the P400 Mike!

It has proven extremely reliable for me and I'm sure you'll find the same thing. Enjoy and keep us all posted.

What turbo are you using?

What turbo are you using?

It has the stock GM-4 turbo in it still with a turbo-master set at 15 psi max. I've looked at a lot of information on other turbos, but since this is my daily driver, as well as my camper hauler I'm hesitant to put a big turbo in it that would be great when towing, but not so great on a daily basis.

I've heard rumors on a new turbo being designed specifically for this motor that I am really looking forward to coming available.

I haven't towed anything with it yet, but I've got 1400+ miles on it already, and it pulls hard... much stronger than the old motor.

The GM8 turbocharger isn't as bad as everyone "thinks" it is. The numbers I pulled in my signature line were with a GM8.

Now, are there better units out there?

Heck yeah, the GM8 has design roots as far back as the early 90's. There's been lots of advancements since then.

Would I be using a Chinese knock off turbo or a Holset take off unit to replace it?

Nope....I'd buy a new one after some serious consultation with a manufacturer. Big bucks though, better get ready to pony up new unit prices plus a premium for going where no one has gone before.

I really like the BW EFR series. Not cheap by a good margin though....

GM8 does what it needs to on my 1993 K3500.
