First start - off to tuner next
 

I started it up for thw first time yesterday. Now it is off to the tuner to get it running right.

2004 lm7 motor out of 2wd chevy silverado. Stock 4l60e transmission. 80lb injectors. Turbo and intercooler from vs racing sloppy mechanic kit. Flipped truck manifolds and custome fabbed 2.5" hot side and 3" cold side. 3" down tube to a race venom exhaust. Boyd tank with in tank pump. Modern vintage systems provided an awesome cut down harness.

I am anxious to see how much power it produces on the dyno.

Nice!!

WOW!!! Have fun with that!

Re: First start - off to tuner next
 

So that is what you do with all of your spare truck exhaust manifolds !!

Nice build!

The stock 4L60E is not gonna last. They're just not up to the task when it comes to the brutal torque of a turbo.

As for the fuel system, how big is the pump and what type of fuel? That'll likely be your limiting factor. If its a typical walbro 255, I'd say 475ish to the tire on gasoline is about it. Watch those fuel pressures and duty cycles closely.

update???!!!

Re: First start - off to tuner next
 

No update yet, still waiting to get in to the tuner.

As for the pump, it is an In-Tank Aeromotive Stealth 340.

I used the truck manifolds flipped over to make the hot side.

I am guessing the trans will last until I put bigger tires in the back. I still have the skinnies on the back, so I wont be able to get much power to the ground.

So I changed direction a little. I just picked up a copy of HpTuners and I am going to do the base tune myself. Final tune will be done by a professional on a dyno.

First step I turned off the VATS and adjusted the fuel injector setting for the 80# injectors.

She runs!!!

sounds great...!!!

Nice turbo Setup. With an engine bay that big, room is still hard to find when fitting a turbo in the mix. Can you tell me what intercooler you used (the size) and did it fit behind the grill? I'm putting a turbo on my 1965 C-10 and not sure what way to go for the intercooler. Sounds Good. Again nice setup and have a good night.

I bought this kit. It is a 3" intercooler 31*12*3. I thought I had a ton of room until I started packing it all in. I have the intercooler infront of the front support, so I will have to trim about 3/4" off the grill. I am not happy having to cut the grill, but I do not think it will be noticeable.

Thanks for the info. Will be looking at your build for updates.:chevy:

Re: First start - off to tuner next
 

Making a bit more progress. The grill is back on with the intercooler tucked in nicely behind. I also got the 2 bar map sensor installed and mounted under thw vortec engine cover.

It is idleing good, so now I need to get it road ready to do some driving tuning.

Re: First start - off to tuner next
 

How was the fit with the grill and intercooler? Any pics of mods you had to make to get it to fit?

Re: First start - off to tuner next
 

I did not take any pics, but I did have to modify the grill. I cut 1.25 inches off the upper flange. No other mods were required. I will see if I can get a decent pic with it on the truck.
