    Got my truck kit from Boost District. Rosh at Boost District is a very knowledgeable guy. And super helpful. I've been pretty happy with the customer service. I haven't got too far into the install and progress will be slow. But the kit covers all the basic and big items and then there are a few little bits and pieces he does not include because of so many different variables.
    The big items in the kit:
    LSA blower
    ZL1 lid
    650cc/60lb injectors
    LSA fuel rails
    Intake manifold gaskets
    Olson Kustom Works Adapter plates and accessory relocation and necessary seals
    Heat exchanger pump and wiring kit
    Upgraded heat exchanger


    I ordered extra:
    Walboro 450
    Made my own crank pin kit, going with 2- 1/4"x3/4" dowel pins
    New crank bolt

    Biggest reason was price. But I also like the novelty of it being a factory gm option and I think the zl1 lid looks good.

    4K vs 6 or 7k can’t go wrong

    Just two crappy pics from this weekend. Got the OKW bracket on. The PS pump lines are a pretty tight fit, and I need to clean up the wires stuffed under the line. And the instructions for the bracket say to reuse you stock idler pulley, but when I mounted it up and put the additional idler pulley on and mocked up the belt around the crank, ps pump, alt, and the idlers I had a hard time getting it on since they were so close to each other and it sure seems like they could even rub so I think I will get another smaller dayco idler like the one included in the kit to give myself a little more clearance. Got the intake off and breaking apart the harness to separate the throttle body harness from the injectors so I won't need an extension harness. Found out I need adapter harnesses too to go from the delphi plugs for my injectors to the newer ev6 plug, but Rosh said those should ship this week. I am a little disappointed since I'm still waiting for the install kit for the walbro 450. Rosh said he was having a hard time getting them from his vendor.

    And I'm really considering the first thing I'll do once it's running is pull it outside and soak the engine with like 3 cans of engine bright degreaser lol

    Blower is on. Gen3 water pump just barley clears the bypass valve with the 1/2" adapter plates. Rosh got me the needed mini delphi to ev6 injector adapters and the fuel pump install kit. Next is get the lid on and clean up the wiring.

    No, the belt goes from the top idler on the right, blower, water pump, tensioner pulley if you traveled counter clockwise

    Lid is on and working on wiring. I had to use adapters to use the newer ev6 style injectors since my truck has the mini delphi plug. I tested the walbro 450 with the stock returnless system in the bucket. I drilled out the venturi jet to .200" and wanted to make sure everything would still work with the larger port.

    I used a ICT Billet throttle body adapter and it looks like I'll need to run my tb upside down. The motor on the side is too close to the blower pulley and the belt will hit.

    Got an AirRaid u build it kit and got the intake together. Gotta hook up some vaccuum lines and finish the wiring for the gauges and will try and turn it over.

    Still chipping away. Getting down to the final details. Glowshift gauges are in. Them seem decent quality. Although the pillar pod was only like $35 and it shows, but I'm not too worried about it. I got the heat exchanger mounted and am pretty happy with how that came out. I used some coupling nuts to make the mount bolt on to the core support pretty easy then the heat exchanger bolts on to there. and I will add some brackets to mount the trans cooler. I am kind of bummed, Rosh said that I needed a Walbro 450 and in reality I really didn't. I started it up and had 65psi fuel pressure and that was with modifying the venturi in the stock bucket. Like all other fuel pump threads on the 450 say, the stock in tank regulator cannot dump the fuel fast enough. I was left with the decision then to either add an afpr and run a return line into the tank, which I really considered, but then also noticed the 450 instructions say that a minimum of 14 ga wiring should be used for that pump and I'm pretty sure the stock wiring is 16 ga. So after pricing it out and seeing it would probably be another $200ish to have the 450 work properly, I instead ordered a 255 to drop in. So if anyone wants a 450 for cheap I have one, otherwise it will sit and maybe I will upgrade the fuel system later down the road if needed.

    Would a 225 have been enough?

    Justin at Blackbear said a 255 would be fine for my current set up. And walbro says they can support roughly 500hp. This is a very similar set up to if I would have got a tvs1900. I believe the 1900 kit for my truck includes a 255lph pump.

    Took it out for the first drive and was very happy with Blackbear's first tune. Sent a data log to Justin and waiting to see what he thinks. Builds 8 psi no problem. If anyone needs the QD connectors for the lid they are Dorman 800-919. Just be aware they are 5/8" barbs you if you are using 3/4" hose you will have to get a barb adapter, which most auto parts stores should have. These are the cheapest I've found for lid adapters. And I believe some people are even just reselling this same piece, but calling it a zl1 lid fitting and charging like double the price. I got mine for 9.99 each. I have a ton of clean up to do on the truck still but it runs and is drivable. Next will be redo the shock tower brace, clean up wiring and hoses. But in the meantime its time to drive it and enjoy it.
