Wow is a understatement. very impressive. wonder if there is room for bigger valves? and who can custom cut a set of cams?

I love this little 4 popper, weight, size, etc.
But I don't love how hard speed parts are to find.

Excellent work on that head.
How much boost are you thinking of pushing?
Any idea how thin the port walls are now?
I know at some point a shop in Cali was making +1mm over sized intake and exhaust valves. When I called them they were out of business or change numbers.

I've also read on here that someone had a small batch of blank cams made up. They weren't cheap. I'm not sure they are even available anymore.

Ill post my numbers in a little while :naughty:

No idea on how thin the port walls are exactly. When I was in there it looked like I could go bigger if I really wanted to. There are a few posts about the bottom side of the exhaust runners sagging when a lot of power is thrown at it. People were drilling and taping the area with bolts to stiffen it up.

Here we go folks

So a while back I bought a turbo set up from vallejo8288 that was originally created by LLV.MA5. In all honesty it was a spur of the moment buy because I knew turbo kits are hard to find for this truck and I needed a place to start.

Since I had a engine in the garage I went about improving the set up I already had. I bolted the turbo, manifold and down pipe to the engine I had on the stand to see if I could add support for the turbo. You can see in one of the pictures behind the engine mount there is a steel plate. I welded up a support to the turbo flange from that location and it worked out perfect. (Ill have to get a better picture of it later)

Since I wanted a daily driver and had the manifold and down pipe in my hands I decided to add heat wrap. I soaked the heat wrap in water and applied it to the pipes. The down pipe was a piece of cake but the manifold took some patience. Once I had the wrap in place I secured it with metal zip ties and cooked it in the oven so that I could spray the silicone sealer on it sooner.

Installing the engine was trickier than I expected. I had to remove an engine mount to allow it to sit in properly. I also installed the transmission along with the engine which made everything a little tighter.

Plumbing the turbo was another big hurtle. LLV.MA5 had installed the intercooler behind the grill where the center bracket for the core support was. This made the grill and core support too flexible for my liking so I relocated it a little lower. With my SS bumper it looks like it belongs there.

Once the engine and turbo was in it was time for a test drive! As you would expect the truck didn't run quite right. As soon as it got into boost the truck would go into limp mode. It also ran so fat that I was shooting raw fuel out of the tail pipe lol (bigger injectors).

All that was left was to get it tuned.

It's good to see one of Jake's turbo kits getting use. An easy way to mount the core support is backwards and behind its bottom mount, and then you can mount the intercooler in front of it and it fits nicely. Then all you need is a longer bolt for the top. That's what I did at least.

That's exactly what I ended up doing. Much better that way.

It's looking really good I like how u put the intercooler in the bumper I want 2 do the same thing once I start working on mine
I would suggest a wider intercooler that the one I got because there is a lot of room and wind to be had down there. I plan on upgrading mine eventually

Are there any plans to take it to the track?
Yeah eventually. The truck has a long way to before it's ready for the track. I was thinking about trying autocross too.

@Sudol94 r u using ur stock fuel jump

I have a pic of it on my Instagram fuenteztom
Yeah the stock fuel pump is holding up just fine. I did replaced my original one because of rust. The fuel tank is a bad design because it holds any rain water on the pump it self.

Alright this I my third time trying to post this.

My hope for this truck as a daily driver was to hit 300hp and still have decent gas mileage (20+mpg)

I took my truck to The Performance Factory here in Concord NC. They put it on the dyno and did three pulls with the truck after working on the base tune. As the pictures show the torque comes in early and flat lines across the rpm range.

I boosted to 6.5psi and it came in about 2800 rpm.

Its best run hit 293 ft-lb and 294 Hp.

The day I got it tuned it was 90 degrees and high humidity. So on a cold day I could easily hit my desired #s.

The first tank of gas I got about 18 mpg because you can get a new toy with out playing with it :D
When I was commuting I would get about 24mpg

Good #'s
And that's just with ported and polishing
Port and polished with 6.5 psi of boost.

From factory these engines make 180hp at the crank. 100+hp gain on low boost was awesome

@Sudol94 I see what looks like some extra holes in the exhaust runners? Is that what those dark spots are? Did you end up filling them, leaving them alone, or what? How soon did they appear when you were cutting the exhaust ports?

How did I miss this thread!

Nice work! I wondered what happened to that turbo kit. That thing was a beast!

Looks like you guys got the IC mounting figured out. Flipping the core support bracket is the way to go.

I always wanted to do a little port work to mine but never got the chance. Glad to see it’s all working out for you.
