I will eventually rebadge it, I just don't want to run around with ghost images on the door so I'll probably have it touched up by a body shop when I do...

And it does alright, its pretty much a dog when comparing 1/4 times. But in the real world it does fine. When I'm cruising at 1600 rpm I'm making around 265lbs of torque where the gasser made up to 330- BUT at literally over twice the rpm (3250).

"Horsepower may sell cars on the lot but torque is what wins races"

All joking aside, I'm satisfied

As seemingly simple as it went I'd be tempted to purchase a 4BT and it's mate and pay you to swap it for me!

Ha ha I would imagine any shop with a welder and a basic torch can pull the swap off. I relied pretty heavily on the world wide web for answers.

Heck here's how absolutely green I was before hand:
-never changed a ujoint
-understood how vacuum works
-changed power steering fluid or pump
-never wired (in a vehicle) anything more than a fuel pump or stereo
-never lifted a bed or taken a hood off
-never removed an engine, trans, or tcase
-never flushed a radiator
-no welding experience (had my buddy from work weld on my engine mounts after I measured them and drilled two holes in each to receive mounts)
-and I did 95% of the work alone and almost always with beer in hand
---the list goes on. Granted it took me much much longer due to the steep learning curve but I guess everyone starts somewhere




And as for the fuel, I can imagine I will only be tickled with the free fuel/timing adjustments and an intercooler to help the temps

I totally agree, I don't have much myself when it comes to performance or under the hood, so much impressed. treat yourself to a case. even though im highly positive you already have once or twice

So its been a while but I thought Id add in what Ive been up to. I just cant leave the truck alone! right around 1k on the highway still no vids or mpg lol!

I have a 3" mandrel bent downpipe, 3" over the back axle to a 4" black chrome tip sitting on the shop floor... I havent put it on yet but looks like the trans filler will be fine where its at... Intercooler in the works, finding a cheap setup that will hopefully bolt in easy-ish
Im having some EGT issues and lag, so Im going to swap the huge exhaust housing for a smaller 12cm housing.. Quicker spool and better cruising temps are what Im shooting for. My baby h1c should be fine on the inducer/compressor side. If not ill probably sell the baby and switch to a hx30w
So I have been really procrastinating on the down pipe seeing how I might be switching it up to a shorter ex housing anyway. Im getting a flexible braided pipe addded in so hopefully it will be somehwat adjustable
heres my current ex housing, going smaller and heres an example of the flex braid

Ended up swapping for a 3.5" tip since i could get it 18" long. I hate the look of fat and short tips. Looking to swap ex housings this weekend. tried a few 0-60 and Im still over 20 seconds lol. exhaust temps are still pretty low so Im looking forward to turning up the pump
