So another order from amazon and I should be all set.

If and when I have to change this valve, ill be going with a 1/8 npt valve.

Hey Choda, I’ve followed along with your progress. Looks like you’re getting it all together nicely.

BSP comes two ways. BSPP and BSPT. Last letter indicates P for parallel and T for tapered.

Comparing this NPT to BSPP the differences are thread angle, form and pitch. NPT in the 1/8” size is 60° angle with flats at the root and the crest of threads. NPT is 27 TPI.

BSPP in the 1/8” size is 55° angle with radius at the root and crest unless truncated. BSPP is 28 TPI.

We machine BSPP threads at my job because the radius is stronger than the flats of the NPT. Another purpose is BSPP will use a seal washer versus sealing on the threads of the tapered thread (NPT). BSPP is common in higher pressure applications.

Worked on the catch can and vac/boost dist block. I like where the block is and how the hoses will be run. I'm not 100% sold on the catch can and routing. I wanted it clean and functional. Also able to be drained easily from opening the hood, not using a remote drain. The hoses are a bit long this way but will tuck under the coil brackets nicely.

For mounting the vac block, I used two head bolt holes with some spacers. It holds the wires close to the engine and keeps short vac/boost hoses. The wiring for the mac valve and boost ref line will follow the harness up along the intake and into the fire wall. Should be clean.

The other way I was thinking was to switch the valve covers so the breathers are toward the front of the engine and the pass hose would run up along the rad and into the can. About 20 inches long. The driver side would be about 8 inches long. Id have to make a new bracket and buy one more -10 fitting. Who knows, maybe ill leave it maybe ill change it.

Mighty mouse quick connect fittings on the intake for Boost source and valley cover for catch can.

Looking good.

Saw upwards of 3psi drop with MBC when I was only running 7#.

With the EBC, once dialed in, i noticed about half the drop in the limited time I had with it. AEM doesn't have the rpm option on mine, so I didn't have the ability to counter the drop. Will see how it goes with new setup and fresh vacuum lines.

7psi down to 4psi at red line is nuts. I thought you were up around 15 psi and dropped down to ~13 psi.

lookin good...cool motion stuff. they have new valve covers and coil brackets now for LT.
I bought their manifold flanges for hotside log and exhaust flange for the single crossover from stock header.

i did look at their boost/vac block but cheaped out and went amazon for 28$.

still eagerly awaiting your drain setup evaluation...

are you using the truboost? old or new model?

I have the 80psi model lol...since they dont make the older one anymore.

I also looked at the amazon ones too but I like supporting the companies that put out good content, share knowledge and have good products. I spent some money with Motion Raceworks for this build. Reminds me, Doug wants pics of how I mounted the block to my head.

Well I'm a dummy and only ordered one exhaust gasket so I only got the passenger side manifold on. I did receive my fancy wires from Granatelli. So far they seem really nice. I had to order custom set because each wire is different length with angled or 90* boots, esp on the turbo side. I swapped out my factory exhaust manifold bolts for some arp bolts with washers. I'm not sure why I bought bolts instead of studs but oh well. I also used a very light coat of rtv orange on the gasket. My tuner used it on the previous engine so I figured to follow suit.

I swapped out my meth pump and cleaned up the wiring and hose. I noticed the hose end fitting is a bit small compared to the fittings and -6 ID. I was going to order up more fittings and hose ends but it worked fine before so I left it.

[Choda]

I did a bit of research and it turns out this meth hose is the one that comes with the kit from Alky control. So I cut it to proper length and reinstalled it. I am a bit surprised it doesn't use a true -6 feed hose into the pump.

Got a little time in the shop and put the turbo kit back on. I forgot how heavy this turbo is. The wrap really pulls away from the beauty of the kit but I'm more about function than looks. Vac block is just about done, I had to wait a week for one fitting only to decide it was ugly and not what I wanted to use. I also noticed that most people have switched to the push lock fittings and 1/4 black tubing. Put that on the "maybe one day ill change it" list.

I ohm tested the granatelli wires just because. Each one was either 0 or 01 resistance. Of course this is the only fing picture the loads right side up. I wrote down the ohm my old msd wires had with the length of them when I ordered the new ones.
Cyl msd Granatelli
1 84 01
2 69 00
3 113 01
4 broken 00
5 103 00
6 55 01
7 89 01
8 broken 00

I am working with a buddy of mine on something really cool that's going to shake up the world once its finalized. I don't want to give away anything but know its going to be amazing.

Choda why didn't you use a ported MSD instead of the GM intake?

[KingLT1]

So there is no chance of potential leaks since the MSD is a 2 piece intake manifold.

$$$ I would if I found one on the side of the thruway. For FI builds, i think the intake manifold would be one of the last updates needed.

Its Possible. I see a lot of blower guys use the msd manifolds. They look great and do make power but I'm not there yet. As you guys know this crap isnt cheap.

I'm using the Procharger intake mainly because it has port injection bungs, it was still almost $3000 though.

One of the major drawbacks on PI with a turbo imo. I heard about the MSD's blowing out and I'm wondering if a Holley Hi Ram (budget) would kill my low end and midrange torque with twins since I have room for it?
